Application of Hydraulic and Sealing Technology in Petroleum Machinery

Petroleum machinery has been operating under high pressure, high temperature and high speed for a long time, which has high requirements on the technology and quality of its seals, so it is particularly important to optimize hydraulic seals. The application of hydraulic pressure and sealing technology can not only effectively replace the sealing effect of conventional sealing rings, but also effectively solve the disadvantages and deficiencies in the operation stage of petroleum machinery, especially for problems such as excessive wear, excessive space restrictions, and excessive workload. . The hydraulic and sealing technology has the characteristics of applicability, extensiveness and relatively strong operability, which can greatly improve the operating efficiency of petroleum machinery.

mechanical steering

Most petroleum mechanical equipment is equipped with a steering cylinder to achieve effective control of the steering of the mechanical equipment. It has relatively good performance and functions, and can effectively improve the efficiency of mechanical steering. In petroleum machinery, the introduction of hydraulic technology can not only improve the flexibility and mobility of construction machinery, but also save energy and improve economic benefits.

mechanical brake

Most petroleum machinery is equipped with a hydraulic system, especially in the gearbox structure, which uses hydraulic technology to achieve effective operation of power, and then achieve the purpose of shifting gears. With the assistance of hydraulic power, the operator can complete the gear shifting operation with only a small force, which can not only reduce the working pressure of the operator, but also improve the gear shifting performance of the transmission. Hydraulic technology itself has the advantages of quick response, superior performance, stability and safety, so it has been widely used in mechanical braking, which can greatly improve the operating efficiency of petroleum machinery.

Construction machinery walking

Almost all petroleum machinery is equipped with hydraulic transmission devices, which can ensure the smooth start and high-efficiency operation of petroleum machinery under full load conditions, and greatly reduce the power loss during operation. Applying hydraulic technology to petroleum machinery can effectively improve the effect of advance and retreat control in walking operations. Therefore, hydraulic technology plays an irreplaceable role in the walking of petroleum machinery.

Construction Machinery Working Devices

During the operation of petroleum machinery, hydraulic technology has outstanding transmission performance, which can effectively improve the operation efficiency of petroleum machinery. Among the existing petroleum machinery and equipment, most of them are equipped with hydraulic transmission control equipment as required, which can not only ensure the smooth progress of daily work, but also effectively reduce the consumption of electric energy and improve the economic benefits of the enterprise. Compared with similar mechanical equipment, it can be found that the speed regulation performance and operating performance of petroleum machinery have been effectively improved, and these are the functions of hydraulic technology.

Application of Sealing Technology in Petroleum Machinery

In petroleum machinery, hydrodynamic pressure radial sealing technology has been widely used. It generally uses the principle of hydrodynamic pressure between the dynamic sealing surfaces to build a corresponding Inducing severe mechanical loss or overheating of the fuselage can effectively improve the service life of petroleum machinery while improving the operating efficiency of petroleum machinery.

Application in Spiral BOP

Nowadays, underbalanced drilling technology has been widely used in oil production, and the spiral blowout preventer is the key equipment in this technology, the most common one is the annular rubber core self-sealing spiral blowout preventer. The research shows that in the actual application process, the main factor affecting the underbalanced drilling technology is the service life of the drill pipe sealing structure and the subcontractor. At this time, relevant personnel need to take effective measures to improve the service life of the drill pipe sealing structure and the subcontractor. In this way, the advantages of underbalanced drilling technology can be better utilized. At present, most researchers pay more attention to the structure of drill pipe sealing technology, but they do not

Without paying attention to subcontracting, the effect of using this technology cannot be effectively brought into play. The hydrodynamic radial sealing technology can effectively solve the above problems, thereby effectively improving the application effect of the spiral blowout preventer and improving the operating efficiency of petroleum machinery.

Application in flushing pipe assembly

Usually, the sealing medium between the center pipe and the lower end of the flushing pipe is mainly drilling fluid, and the connection is realized by means of a dynamic seal, so that the damage resistance and high pressure resistance of the flushing pipe can be effectively exerted. In the faucet, the flushing pipe assembly is a relatively critical component, and its service life is particularly critical. In the sealing process, if you choose the traditional sealing technology, it will not only fail to improve its service life, but also cause its sealing quality to be greatly reduced. In the flushing pipe assembly, the application of sealing technology can solve the above problems in a timely and effective manner, and effectively improve the operating efficiency of the flushing pipe assembly while prolonging its service life.

Application in Progressive Cavity Pump Oil Production System

In petroleum machinery, the screw pump oil production system is driven by ground machinery that is widely used. The system mainly uses the rotation of the polished rod to drive the movement of the sucker rod, and then gives full play to the linkage effect of the screw pump oil production system to ensure the smooth progress of downhole operations. . In the specific implementation process, due to the influence of various factors, there are certain defects and deficiencies in the screw pump oil recovery system. For example, the sealing method selected by the polished rod dynamic seal is not complete, which will not only increase the difficulty of maintenance of the screw pump oil recovery system, but also Induce the pollution of the surrounding environment, which is not conducive to the development of the petroleum industry. In order to effectively solve the above problems, it is necessary for relevant personnel to reasonably select the sealing technology based on the operating conditions of the screw pump oil production system, and through the development of the polished rod seal combination suit, the bushing is installed on the polished rod sealing part with the help of the dynamic pressure sealing ring, so that the entire screw The versatility and lubricity of the pump oil production system are effectively improved.
