Currently, gas lift valves are widely used in the gas industry to maintain pressure in wells. However, there are often problems with sealing valves, which leads to a loss of efficiency and increased energy consumption. Improving the operability of the sealing element of the gas lift valve will reduce the likelihood of gas leaks and increase the reliability and efficiency of the entire gas lift device. In addition, this will reduce the cost of repairing and replacing faulty sealing elements and improve the economic efficiency of gas production. The sealing element of the gas lift valve plays a key role in ensuring reliable and efficient operation of this device. A malfunction of the sealing element can lead to a gas leak, which will entail significant financial losses and risks to the safety of personnel and the environment. Therefore, the urgency of improving the operability of the sealing element of the gas lift valve is to ensure the safe and reliable operation of oil and gas equipment, improve the economic efficiency of production and reduce financial losses of companies engaged in gas production and transportation. The purpose of the work is to study the provision of a gas lift valve and a check valve with a flexible, sealing element and means to protect the element from deflection or destruction. Keywords: gas lift valve, Bellows type, Valve sealing, Composite materials, Fluoroplast-4, Carbon fiber, Socket for the sealing.

A hydraulic drive is a set of interacting hydraulic devices that is designed to be ghosted by means of a working fluid under pressure. The main element in hydraulic drives most machines is a power hydraulic cylinder. Hydraulic cylinder refers to volumetric hydraulic devices, since their operating mode is to fill the volume of the working chamber and empty it. The very principle of operation of the hydraulic cylinder is based on the movement of the worker organ (piston, membrane, plunger), under the influence of the energy of the flow fluid or the mechanical energy of external forces (gravity, spring).Depending on the principle of operation of hydraulic cylinders, it can be divided into two groups: one-way hydraulic cylinder, two-acting hydraulic cylinders. To ensure the operation of the hydraulic cylinder, a pump is required, the purpose of which is to convert mechanical energy into the energy of the flow fluid. Studying the stiffness of a hydraulic cylinder can help determine the optimal load that a hydraulic cylinder can withstand, as well as help in choosing the right size of hydraulic cylinder for a particular system. The stiffness of the hydraulic cylinder can be determined by measuring the movement of the hydraulic cylinder as the load increases in a given range. For example, a hydraulic press can be used to increase the load on a hydraulic cylinder to a certain value, and then a measuring tool can be used to determine the movement of the hydraulic cylinder. This data can be recorded on a computer, which can then be used to analyze and calculate the stiffness of the hydraulic cylinder. The stiffness of the hydraulic cylinder can be expressed in newtons per millimeter or other units depending on the specific measurement system. By using various materials (indicated in the literature), the results of studies aimed at determining the reduced volumetric stiffness of high-pressure hoses and the dependence of the reduced volumetric stiffness of the hydraulic cylinder on the change in the volumes of the working cavities in the process of moving its rod are given. Keywords: hydraulic system, volumetric stiffness, hydraulic cylinder, module, hydromechanical systems, hoses, pressure, rod, dynamics.

Crane parts work with non-stationary variable loads. The hypothesis of linear summation of fatigue damage during non-stationary cyclic tests is not confirmed. Under the influence of alternating stresses, a process of gradual accumulation of damage occurs, which leads to the formation of cracks of various nature, which gradually increase, forming macroscopic values. The work is devoted to the study of stress concentratıons leading to damage to crane parts. The results of the research revealed that the set of possible methods for non-stationary modes is not considered valid and was not fully justified from a physical point of view. From a physical point of view, the direction of the ongoing processes is determined by the method of lowering the curtain. However, this method itself requires further development and accuracy. The application of the Dahlgren method is a manner that inaccurately describes the process and its application is incorrect. When choosing materials that work for fatigue in non-stationary modes, along with other characteristics, it is necessary to take into account the criterion of sensitivity to loads.

A hydraulic cylinder is a volumetric hydraulic motor that converts the energy of the fluid flow into various types of movement of the output link. The use of volumetric hydraulic drives with a hydraulic cylinder working element in all possible fields of industry does not require high capacities. One of the advantages is the ease of operation and overload protection. There are also disadvantages. For example, the hydraulic cylinder depends on the working fluid and in case of contamination it may fail, and therefore the reliability of the hydraulic cylinder decreases. In order to protect hydraulic cylinders from moisture and dirt entering them, as well as to increase their reliability, seals with dirt-removing rings are provided. When assembling or disassembling hydraulic cylinders, important conditions must be taken into account, since failure to comply with these conditions can lead to a defect. Considerable efforts have been made to the parts, so some manual operations are excluded when assembling and disassembling hydraulic cylinders. The reliability of the hydraulic cylinder and, consequently, its reliability are the main topic of the study. Hydraulic cylinders can be of translational action and rotary action. Translational ones include: piston, plunger, telescopic. Reciprocating, in turn, can be one-sided and two-sided. If it is required to create an effort in only one direction, a one-way hydraulic cylinder is designed. At the beginning of the work, a diagram of a volumetric hydraulic drive and its principle of operation is presented. Special attention is paid to assessing the reliability of the hydraulic cylinder. In conclusion, the results of the analyses and the conclusions of the calculations are given. The change in the reliability of the hydraulic cylinder over time was also indicated and the reasons for this change were named. Keywords: Reliability, hydraulic cylinder, hydraulic drive, failure, reliability assessment, pipeline, pump, valve, operating time, hydraulic distributor.

The state of light industry in the world is still difficult. The downward trend in the production of the most important types of textile products in physical terms continues. An inevitable consequence of the decline in light industry output is a low level of capacity utilization. The situation in the light industry is further complicated by the fact that most of the existing fixed assets cannot be used in the future without appropriate reconstruction, since the technical and economic parameters of the main part of the equipment do not meet modern requirements and do not ensure the production of competitive products. The international experience of recent years shows that machine building for the textile and light industries has good prospects for overcoming the crisis and further development. Intensive improvement of technology for these industries is carried out in the following main areas: • improving equipment performance; • equipping machines with the most modern microprocessor control and monitoring systems for the technological process; • robotization of labor-intensive operations for machine maintenance; • universalization of equipment for various processed raw materials. Based on the concept of development of textile engineering and the current economic situation in the textile industry, the main areas for improving production are: • modernization (improvement) of mastered production and mass-produced equipment in the direction of increasing the productivity of machines, increasing the degree of their automation, reliability, ergonomics and workmanship, as well as saving raw materials; • modernization of equipment operating at textile industry enterprises by replacing individual units, modules, equipping machines and units with automation and instrument control. To meet the needs of the population for the product of the textile and light industry, it is required to increase the production of fabrics of various assortments. The quality of manufactured fabrics depends on the construction of the mechanisms of looms. One of the mechanisms that affect the quality of the fabric produced on weaving machines is the fabric removal mechanism. This mechanism consists of three devices, a pulling roller (valiance), a commodity regulator and a winding device. Keywords: Light industry, fabric removal mechanism, winding device, valiance, coefficient of friction.

In the presented article, the analysis of the effect of the dynamic load falling on the polished rod of the sucker rod pump unit on the normal function of the operating unit during the oil extraction process was carried out. The general formula for the damage caused by the impact of the pump's wellhead packing seal has been derived. The dependence graph of damaged work on the length of the packing seal and the Poisson's ratio of the material was made. Due to the dynamics of the frictional force generated in the packing seal of the stuffing box appropriately located below the suspension point of the rods, its forced cyclic movement occurs as a result of the impact transmitted to the system which consists of an incompressible fluid column, and the elastic rods. This requires the investigation of the dynamics of the rod pump associated with the probability of unpleasant situations such as the possible resonance occurrence in the specified system, the time between repairs, and the reduction of the working coefficient of the pump, in this regard. At the same time, the questions such as the coefficient of friction depending on the selection of the material of the packing seal, the reduction of the dynamic accumulation of the load on the system, and the saving of electric energy are also important. It needs to be considered that the operation process is accompanied by a certain energy loss. It should be taken into account that even a small reduction in energy loss can manifest great economic benefits. It should be noted that some issues encountered in the process of operation of oil wells through the rod pump and depending on certain arguments affecting this process were also resolved by those experts.

A hydraulic device that is used to suck up liquid, move it under pressure or pump it, is called a pump. As a rule, any movement of a liquid by similar aggregates is carried out due to the transfer of potential or kinetic energy to it. Depending on the technical indicators, different types of pumps are used. At the same time, they differ in efficiency, power, volumes of fluid pumped per unit time, maximum head and resulting pressure. The most used group of pumps are vane pumps. Their distinctive feature is the impeller rotating in a fixed housing, equipped with blades. Depending on the warehouse of the impeller and the conditions for moving fluid through it, vane pumps are divided into centrifugal and vortex. With a centrifugal pump, liquid is supplied due to the centrifugal force that appears when the impeller rotates. She is carried away by the blades and, under the action of centrifugal force, moves from the middle of the wheel to the edges along the blades. The blades of the impellers are bent in the direction of rotation backwards. The number of blades is usually from 6 to 8 pieces. But special pumps for impure liquids, in order to increase the cross section of the channels in the wheel, are installed with a smaller number of blades from 2 to 4 pieces. Centrifugal pumps are usually installed above the liquid level in the receiving tank, so they must be filled before use. The pump is filled with a check valve on the suction line through the filling funnel until the gas is completely expelled from the suction pipeline and the pump housing. In the absence of a check valve, for filling, air is forced out of the pump housing with the valve closed by a special vacuum pump. The same is done when filling large pumps. Centrifugal pumps are characterized by a rather high efficiency, compactness and durability of use. Based on the numerical modeling of hydrodynamic processes, a substantiation of adjustment of the design of the working wheels of centrifugal pumps is given. Mathematical modeling of the fluid flow in the running part of the centrifugal pump is performed. The results of the CFD calculation are analyzed, after which an experimental work wheel is created, and its tests are carried out. There is a process of comparing a serial and experimental pump. Keywords: Centrifugal pumps, numerical modeling, mathematical model, energy characteristics, hydrodynamic processes, dynamic characteristics, power engineering, working wheel, working fluid, working wheel vanes.

In recent years, the oil and gas and other industries have been increasingly used turbo-gas compressors (TGC). Prospects for use of TGC at compression stations (CS) is associated with their large motor resource, energy consumption and autonomy that do not require additional energy supply. The present paper is devoted to the creation of booster compressor stations with high reliability to ensure uninterrupted operation that meets high standards. In this connection, the collection of associated low-pressure petroleum gas for compressing and transporting it to the shore was the most urgent task in the acute shortage of natural gas. The performed analysis of the literature published showed that a significant number of works were devoted to the problem of ensuring a high level of reliability of compressor units. At the same time, there are no statistical data on failures necessary for deep analysis, the reasons causing certain equipment failures have not been sufficiently studied. This does not allow to provide the necessary level of reliability when upgrading the existing and designing new compressor units. It also requires the solution of a number of other problems related to ensuring reliability at the stages of design and manufacture of units. When developing and creating a new generation of TGC at the design stage it is necessary to carry out appropriate calculations to ensure the future safe operation of CS. To carry out these calculations, it is necessary to develop new scientific approaches and mathematical models on the basis of which it is possible to obtain more reliable results about the behavior of TGC in future operation. Similar calculations should be carried out for both existing and operating TGC in order to assess their suitability for work and to predict the life of the main working elements of TGC and CS in general. Keywords: reliability, boost compressor stations (BCS), gas turbines, compressor units, operating time, failure.
