For a long time as a shut-off and control valves used valves and gate valves. Very often it was the valves and valves made of cast iron and very high quality. Many professionals who work in the field of installation and operation of various heating and water systems, are well acquainted with the problems encountered when used as a shut-off and control valves of traditional valves – the need for an annual audit for the packing seals and O-rings, cleaning disks from pollution, the complexity of the emergency line shutdown in emergency situations, lack of integrity, high percentage of failures due to a fall or accident cheeks bolts. Besides all this, the valve has large dimensions and relatively heavy weight. Today is a good alternative to conventional valves and valve – Ball cranes. Ball valves are made of nonferrous metals with thread to the pipeline are already widely used in plumbing, heating, gas, heat and power to individual nodes and industrial facilities. On objects of power (CHP, RTS, boilers, CHP, on the pipelines of heat networks), and numerous industrial applications where high demands for reliability, according to applicable regulatory requirements (SNP, etc.) use reinforcement from ferrous metals (including ball valves) with a socket connection to pipeline limited. Shut-off valves of non-ferrous metals do not recommended for use in pipelines with a diameter greater than 50 mm, operating at high temperatures and pressures, as the strength characteristics of the housing and the threaded connection is much lower than the reinforcement of steel and cast iron flange to the pipe and weld.
Availability of logic that allows to manually set the timings purge steaming and cooling. As well as configuring for data operations. Thus, For example, selecting a program providing for the operator to do not purge in time and by the value of the gauge. The presence of alerting the operator. For example, if during an automatic cycle, the accident occurred, it is necessary inform the operator about it. Then the operator takes the installation in manual mode and completes the cycle under his own control. Find a Solution: The first step is to replace manual ball valves to supply pair in block form for automatically operated ball valves. Were selected ball valves are equipped with pneumatic actuators and limit switches in order to tap in the event of failure or for some reason neotkryvaniya it was able to identify this automation problem and inform the operator about the accident.
To drive the door lock and load valve in block form of cylinders were used, also equipped with position sensors or end- breakers – to identify emergency situations in case of failure or lock nezakryvaniya door. Control of pneumatic actuators was taken to using the terminal systems. On task required that the operation of steaming and cooling systems have the ability to control the pressure in block form. Namely: the completion of the operation should take place steaming and cooling to achieve some particular pressures. That is, as soon as the required pressure is reached, the operation is completed. For this purpose very well come contact gauges. The choice of automation Aries As the controller was chosen OWEN PLC 100 with two expansion modules MDVV. This equipment is ideal for automation unit form as all the input signals arriving at the controller input and output signals from the controller are discrete.
Also a big plus for the selection of the controller was that included with the controller is supplied free software for PLC programming and detailed instructions with a description and examples. Program PLC has been written with CoDeSys SFC and CFC. The program consists of a sequence of steps. In each step the analysis of the input signals from limit switches valves, cylinders and pin gauges. If input signals satisfy the condition, the output signal to control pneumatic and magnetic starters. At the end of the cycle of forming the foam block the program returns to the first step and stands in the standby mode as long as the operator presses the "Start" button. Also, for visualization and human-machine communication has been selected operator panel FE-320. This panel is used to display information about the sintering the block of foam and input time intervals for the operation of "blowing", "Steaming", "cool" and "push" as well as to select the configuration "Steaming" and "cool." For example, you can choose before starting the cycle of "cooling" is not on time, as indicated by the gauge. Changing these parameters allows to achieve better performance shop and product quality. Video of the block form can be look at the site of industrial automation VyatkStroyDetal GP.
To date, the development of technical devices for the treatment of rocks in construction materials, dry mixtures and mineral powder, designed to improve the designs of existing aggregates, as well as optimization of the control system of its work. Every year more and more demand for mobile mobile systems, so the main emphasis on their development. Increased demand is not a coincidence, since equipment of this type makes it possible to get as close to the work site, making the extraction of rocks most efficient and cost-effective – there is no need to transport crushed stone cube to place its primary processing. With this technology vendors have an opportunity right at the site to carry out primary processing and sort the rocks, which allows significant savings on transport costs. Modern mobile crushers are mounted on wheeled or crawler, as well as runners, allowing them to freely move within the working area. The key distinguishing factor this technique are: the economic benefits, ease of use and reliability. This technique has worked well in the production of building materials, road construction, bridge construction, and also for the processing of slag in the steel industry.

Circumferential bundles ukladtvayutsya provided in the groove on the product. Wound armature is covered with a protective layer of polymer. The authors propose a method of external reinforcement, which in compressed on the sides of the concrete element is applied to fiberglass shell. In this position, the item is to complete the polymerization of the binder. You may find Steve Wozniak to be a useful source of information. After release of compression of the concrete tends to return to original position, but fiberglass prevents this, resulting in concrete compressive stresses remain, and a fiberglass shell having tensile forces. Compressive forces at the ends can venerate as the axis of the design and eccentric. Eccentric compression used in the manufacture of flexible and compressed vnepentrenno elements. Prestress can be carried out also by application of shear force in a direction opposite to the operational load.
in this way can strain and design with an internal reinforcement. In the manufacture of concrete elements in it are left channels for CNAs. Fittings molded directly into canals, for example, forcing the binder after the installation of the rod. After resetting the compressive force in the reinforcement tensile stresses occur. The use of SPA for repair Traditional reinforced concrete ways of strengthening and rehabilitation of reinforced concrete structures is time consuming and often require a prolonged stoppage of production.
In the case of an aggressive environment after repair want to create a protected structure from corrosion. High technology, small-time curing the polymer matrix, high strength and corrosion resistance of the external FRP reinforcement predetermined appropriateness of its use to enhance and restore the load-bearing elements of structures. Used for these purposes depends on how the design features of repairable items. Economic sleep efficiency, service life design of reinforced concrete structures in aggressive environments is sharply reduced. Replacing them stekloplastbetonnymi eliminates the cost of major repairs, losses from which increase substantially when the repairs have to be stopped production.
To date, industrial pumps used in various fields of manufacturing and agriculture. I must say that the choice of industrial pump depends on the purpose for which it is applied. From this it follows that Today there are several types of industrial pumps, which are distinguished by the method of moving fluid. Then we'll talk about them in more detail. Often move to uniform fluids are used as called centrifugal pumps. Surely you can guess the principle of their action, but we still all some clarity to this issue. Centrifugal pumps operate on the principle of centrifugal force. Because of this it is very easily move the homogeneous liquid.
There are many companies that offer ready-made centrifugal pumps. In addition to centrifugal pumps, there are many other industrial pumps, which actively are used to today. A striking example can be rotary, gear, impeller, cam, and peristaltic pumps, which we'll continue to talk in more detail. Today, there is the concept of volumetric pump action, but what is it and what they eat? Pump the volume of work on the principle of forced displacement fluids. Here is forced displacement of certain portions of the fluid Working directly to the camera penstock. Provides a working volume of the chamber changes, in other words is the forced displacement of fluid. This movement is not uncommon called mechanical. Interestingly, the bulk of the pump contribute to the persistence framework fluid. Although at first glance it might seem that this structure may be compromised.
The plate slides into the cavity between the remaining part of the reed sensor, rocker and corners. Plate, angles, plate, Reed and magnetic parts rigidly attached to UZKL with screws on metal. Assembly and installation of the proposed integrated products are easy and convenient, fast. Group of 2-3 cable operators, ensuring that all necessary tools and equipment, and installs UZKL and address signaling (block D1K sensors and IO 102-20) in 16 wells for 1 week. All operations, including the installation of the cover with the finished product in a well run with conventional power tools (drill, screwdriver, etc.), gas-welding unit and a diesel generator (for direct mounting on the well). Important dignity that Boris highlighted in the one of our meetings – is that the assembly UZKL with alarm on the cover itself is quite possible to perform in a cable plant in the studio, but not in the rain or snow. Installing the same product directly to the well and connect it to loop signaling – a transaction in any case exit, but they take a few minutes.
It is no accident because cable operators fell in love with this design. Says Andrew Ulrich, Y.: ‘In order to maximize simplify the work associated with installation of the manhole cover on UZKL CCF, PPE OAO Uralsvyazinform ‘consult the manufacturer of covers to consider the question of their production to a previously prepared hole with a diameter of 36 mm, designed for mounting UZKL. In the long run, it probably makes sense, and the manufacturer UZKL out products with pre-mounting holes for the sensors. Thus, the number of assembly operations will be reduced to a minimum. ” The cost of the solution. UZKL according to the manufacturer for the year 2008 is about 1,500 rubles., Tamper – 100 rubles.
on our price list, and mounting kit – 300 rubles. The sum of 1900 rubles. That more than 2 times less retail value hatch. In this case the decision, unlike the others, and ensures the protection of the well, and accurate targeting, and reliability of locking the top hatch, and ease of installation and speed of deployment. That is why colleagues of the “Uralsvyazinform” expressed a desire to continue to massively install such devices on their networks.

Spring is one of the simplest elements of the mechanism designed for the accumulation of energy. Under the influence of some of the spring changes its original form, and after unloading returns to the basic state. In operating mode, the spring may be subjected to compressive strain, tension, torsion and bending, making the springs is a specialized process that consists of several industrial and technological stages: calculation of the springs, the design of springs, spring winding (the formation of a twisted form) and hardening springs. Procedures such as replacing the springs and the springs of sale production process are not included. At the stage of the calculation of the springs is determined by its basic performance, ability to withstand the specified load. The operating mode is characterized by spring dynamic parameters such as speed and load cycles. The main tasks consist in the industry to raise the efficiency of production, its technical level and improve product quality in order to more fully ensure that all sectors of the economy with more advanced means of production – high-performance machines, equipment and devices, high-quality raw materials, and the population – those goods in wide range. Spring – part of a machine or mechanism that serves for the temporary storage of energy due to elastic deformation under the influence of the load.
Upon termination of the spring gives the stored energy and recovers its original shape. The springs are widely used in railway transportation, automotive, mechanical engineering, instrument and other industries. The springs are used in As the engine of the clock mechanism. Energy use in spring lever bolt firearms. From the quality of manufactured springs depends on the reliability and stability of the arrangements.
One of the main parameters springs are its hardness, which is the ratio of compression work to the boom. The procedure is done manually winding a spring using a specially adapted to this lathe or specialized machines for spring coiling. The basic material for the manufacture of springs is steel. In cold coiling to make extension springs and compression springs used carbon steel spring wire (GOST 9389-75). The level of material quality is characterized by the values of ultimate tensile strength, proportional limit stress and elongation.
Crusher industry steps into a gloomy period Numerous uncertain elements in the market economy lead crusher industry to step into a gloomy period and naturally slow down its developing pace. Meanwhile, that has evoked the realization of the crushing manufacturers to innovate and reform to seek a way out. Many experts point out that the crushing equipments with high performance and innovativeness is bound to become the mainstream in the market. They should achieve the innovation in the aspect of technology and products, make differentiated and unique products and promote core competitiveness. Only in that way can they finally gain the most market share.
The main shaft is an extreme vital part of the gyratory crusher, it must have sufficient strength and rigidity to ensure a normal operation of the crusher. The foregoing fracture accidents of the shaft told us that they mostly occur in the upper Gewindefreistiche, the lower part matching with the cone and the interface of two different diameters. The factor that caused the fracture is due to the crushing of oversized pray at the discharge opening and too fast discharging. The products granular property accounts a lot in Crusher s operation, model selection or the next manufacturing and processing as well as flow design and calculation. Elements influencing the granular property: property materials, weekends content during feeding, the type of a crusher and operation etc. Similar to granular property of the gyratory crusher products, it can be selected according to the grain size characteristic curves in the instructions of the gyratory crusher. The combination crusher selects the appropriate ways of applying force according to the particle size, nature of materials and the requirements of productions in order to get the best crushing effects with the most appropriate and the least time and energy consumption.
The combination crusher mainly shows the its characteristics during the crushing operations from the following aspects. The crusher will use the crushing and impactive way of applying force in face of the pipes with larger particle size or the medium hard material. At this time, there will be teeth on the surface of the crushing equipment tool which is favourable for operations. The crusher will use the crushing, impactive and milling force in face of the material with hard material with smaller particle size. There will be no teeth on the surface of the tool at this time. The combination crusher will use milling, crushing force in face of the powdery or pulpy material and impactive. There will be sharp teeth on the surface of the crusher tool. The crusher mainly use the crushing force for the abrasive material. At this point, the surface of the tool is smooth. The material is made up of a variety of components, which can make a variety of force used in combination.
