NPF AViS About company news Press about us Product Catalog Metalworking Equipment Contacts news 02/15/12 At the age of 65, the deputy director of LLC NPF "AViS" 07/13/11 Improved driving directions to OOO NPF "AViS" Our contacts: Izhevsk, st. Telegin, 30. tel .: (3412) 609-765 tel./fax : (3412) 609-567 Research and production firm "AViS" Our company was founded in 1993. We began to work under the name of OOO NPF "AViS" in 2005 as a result of the reorganization of a previously existing enterprise for the production of parts for cars of the automotive industry. Since 2005, the main activity of the company " AViS " is the production of high-quality equipment for the oil industry of mechanical engineering. Over the past time, we have been able to concentrate intellectual and production potential, which has led to mobility in performing complex technical tasks in a short time. Oil equipment from the company " AViS " is a high-quality component, contributing to the most rational process of oil production. Research and production firm " AViS"also glad to offer you metalworking services .

The check valve is used to give the working medium the desired direction, and this direction is the only one, which excludes the possibility of reverse movement of the working medium. There is a swing check valve and a lift check valve. The check valve comes with a mesh, used for oil and water intake devices. Such a valve is called a suction valve. Check valvealways set in a single direction. In order to increase the sensitivity of the check valve to a change in the direction of flow, the disc is equipped with a spring or a weight, but this is fraught with a loss of head and, of course, the consumption of energy spent on moving the working medium. There are cases where the check valve must allow the natural circulation of the coolant. In such check valves, full shut-off is carried out with a reverse flow higher than the calculated one, but even in this situation, circulation does not stop, since there is a small hole in the check valve disc, which is responsible for the necessary circulation of the working medium. Check valvecan also be used as a non-return shut-off valve. To realize this possibility, the check valve is equipped with a spindle or some other device that will allow the disc to be pressed against the seat, fixing it. By their design, lift check valves are simpler than rotary ones, but, nevertheless, they are not inferior to them in reliable tightness. The disadvantage of a lift check valve is that the valve plug may become seized when working in dirty media. Therefore, lift check valves are used for relatively clean media and small bore diameters. In other cases, it is more advisable to use a rotary check valve. View check valve in the product catalog What is metalworking? Metalworking is a set of measures to give products a given shape. We use only the most modern high-precision equipment capable of performing the most complex metalworking tasks for any product. Metalworking has long been widespread in many branches of mechanical engineering. With the development of the economic potential of our country, the need for high-quality metalworking of products only increases. This entails the development of metalworking equipment, the need for highly qualified personnel, the creation of a special service for metrological control of the products being created, etc. Metalworking is divided into many operations, each of which contains its own nuances and is the subject of special study. There are simple cutting, gas plasma cutting, plasma cutting and laser cutting of metal. Simple cutting, as one of the varieties of metalworking, optimizes transport. Unlike gas-plasma cutting and laser cutting, metalworking allows you to obtain parts of specified dimensions with a high degree of accuracy and maximum mobility, which is undeniably a big plus for mass production. In addition, metalworking allows you to get any configuration of parts, in contrast to cutting. Therefore, for the processing of parts of various shapes, the AViS enterprise specializes in metalworking equipment. Further, metal processing (for example, for welding) necessarily contains the processing of metal edges using abrasive wheels. The manufacture of certain products from blanks of a corner, reinforcement, a beam, a channel is often necessary in construction operations, which, of course, are easier to put on the shoulders of professionals than to organize a special section on our own territory. In general, it can be noted that the maintenance of its own fleet of equipment, as well as all the accompanying materials, is very expensive for any kind of organization's activities. Optimize your business - entrust metalworking to professionals! When are valve pairs used? Valve pairs are typically used in pump designs for the production of viscous oil. The use of valves of this type is always economically advantageous. This is achieved by extending the turnaround period, and, often, at the expense of additional oil produced. The valve pairs are available in both standard and special designs. View valve pairs in the product catalog What are ESPs for? ESPs are electric centrifugal pumps. ESPs are designed to pump out formation fluid with a capacity corresponding to each pump model. The ESP is supplied in the configuration that will be of interest to a specific consumer. This makes it possible to have equipment that will fit any well. ESP(Installation of an electric centrifugal pump) can be used to pump out liquids that contain sand, gas, as well as corrosive elements, mechanical impurities. During the operation of the ESP, if the concentration of impurities in the pumped out medium exceeds 0.1 gram / liter, the pump may become clogged. Because of this, water can get into the SEM, vibration increases, the engine overheats, as a result of which the ESP stops working. Therefore, for each well, the correct selection of ESP is required. Why are sludge traps used? Sludge traps are used to trap and remove metal scrap from the bottom of the hole that occurs during the drilling process. Sludge traps can be operated with a turbine drilling method, as well as with a rotary one. To bring the sludge traps into working condition, they are installed in the assembly of the lower part of the drill string above the bit. The liquid stream lifts the scrap particles, which, in turn, enter the inner part of the trap and are extracted along the left-hand tape thread into the lower part. Fastening of sludge traps, as well as their release, is carried out with machine keys when the rotor is stopped. View sludge traps in the catalog What is a drain valve for? The drain valve is designed to drain fluid from the tubing stub. This creates a predetermined pressure in order for the drain valve to come into operation; the break of the neck of the tear-off rod is carried out, then the valve piston is extracted from the cylinder, thereby opening the passage of liquid through the holes in the valve. To use the drain valve again, you need a new rod calibrated to the specified pressure, which is supplied to the spare parts. View drain valve in the catalog © 2008-2016 " NPF" AViS ".
