Description

Technical Field

[0001] The invention relates to the field of hydraulic technology, in particular to a hydraulic station of oil production and drilling facilities. Background Art

[0002] The hydraulic station of oil drilling facilities is a key equipment used to provide power source and control system in the oil extraction process. It drives the operation of drilling equipment by converting mechanical energy into liquid pressure energy. The main function of the hydraulic station is to control the direction, pressure and flow of hydraulic oil flow to achieve precise control of various machines in drilling operations and ensure the efficient operation of drilling equipment.

[0003] The hydraulic station in the prior art usually includes basic components such as an oil pump, a control valve group, an oil cylinder, and an oil tank. The hydraulic oil pump is responsible for extracting the oil in the oil tank and sending it to the control valve group through a pipeline. The valve group controls the action of the hydraulic cylinder by adjusting the flow and pressure of the oil, thereby driving the drilling equipment to work. The oil tank is used to store hydraulic oil and maintain the supply of oil in the system. The oil flows through the pipeline system, and after being adjusted by the control valve group, it finally enters the hydraulic cylinder to achieve actions such as pushing or lifting the drilling tool.

[0004] However, some hydraulic stations in the prior art have some problems under high temperature, high load and long-term operation. First, the traditional temperature control system usually lacks efficient heat dissipation and refrigeration devices, which causes the hydraulic oil to be too hot after long-term operation, thereby affecting the stability of the hydraulic system and the life of the oil. Secondly, the existing filtration system cannot avoid impurities in the hydraulic oil. Especially in harsh working environments, impurities will enter the hydraulic system, causing component wear and system failure. In addition, the existing hydraulic station design lacks effective control of vibration and noise, which may have an adverse effect on the operating environment, affect the operator's work comfort, and cause long-term damage to the equipment.

[0005] Therefore, the present invention proposes a hydraulic station for oil production and drilling facilities to solve the deficiencies of the prior art. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a hydraulic station for oil production and drilling facilities, which solves the problem in the prior art that the hydraulic station has insufficient temperature control, filtration and vibration control, thereby affecting the stability and efficiency of the system.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A hydraulic station for oil drilling facilities, comprising an oil tank, a hydraulic oil pump and a control valve group are respectively installed on the top of the oil tank, a connection port is installed at one end of the control valve group, a filter mechanism is installed at the bottom of the control valve group, a temperature control mechanism is provided on the periphery of the oil tank, a bottom plate is slidably provided at the bottom of the oil tank, and a plurality of buffer mechanisms are provided inside the bottom plate; The temperature control mechanism includes a sleeve shell, which is sleeved on the outer circumference of the oil tank.

When the hydraulic oil passes through the filtering mechanism, it can effectively remove impurities in the oil, prevent impurities from entering the control valve group and the high-pressure pipeline, reduce the failure rate of the hydraulic system, and improve the overall performance and reliability of the hydraulic station.

[0028] Please refer to the attached Figure 8 The mounting assembly 7 includes an insert rod 702, which slides inside the mounting shell 601. A filter plate 705 slides inside the mounting shell 601. A pull block 701 is fixed to one end of the insert rod 702 close to the mounting shell 601. One end of the insert rod 702 away from the pull block 701 is slidably connected to the inside of the filter plate 705. The insert rod 702 is connected to the pull block 701. The insert rod 702 can be driven to move by pulling the pull block 701, and the other end of the insert rod 702 is connected to the filter plate 705. Therefore, the insert rod 702 will exert a limiting effect on the filter plate 705. A limiting plate 704 is fixed to the periphery of the insert rod 702. The limiting plate 704 is slidably connected to the inside of the mounting shell 601, and a compression spring 703 is fixed to the side of the limiting plate 704 close to the pull block 701, and the end of the compression spring 703 away from the limiting plate 704 is fixed to the inside of the mounting shell 601, and the limiting plate 704 is fixed to the outer periphery of the insertion rod 702. When the insertion rod 702 moves, the limiting plate 704 will move with the insertion rod 702, and the other end of the limiting plate 704 is connected to the compression spring 703. When the limiting plate 704 moves, a force will be applied to the compression spring 703, and the function of the compression spring 703 is to push the limiting plate 704 to move when the squeezing force of the limiting plate 704 is lost.

[0029] Working principle: Before the hydraulic station works, first check all parts of the hydraulic station, then install the installation shell 601 at the extraction port at the bottom of the control valve group 9, then flip the slide cover 603, pull the pull block 701 in the slide cover 603, so that the insertion rod 702 slides in the installation shell 601, so that the limit plate 704 moves accordingly in the installation shell 601, and in the process of the movement of the limit plate 704, it will also apply a force to the compression spring 703, so that the compression spring 703 contracts, and after the insertion rod 702 slides into the installation shell 601, The filter plate 705 can be installed in the installation shell 601, and then the pull block 701 can be loosened. At this time, the compression spring 703 loses the force of the limit plate 704, thereby generating a reset movement to push the limit plate 704 to move. When the limit plate 704 moves, the plug rod 702 will slide into the filter plate 705, thereby limiting the filter plate 705, so that the filter plate 705 is installed in the installation shell 601. At this time, the filter installation is completed, and then the pipeline is connected to the connection port 10 to ensure that the hydraulic oil can smoothly enter the drilling equipment; Then, the hydraulic oil pump 8 and the control valve group 9 are started to extract the hydraulic oil in the oil tank 1. When the hydraulic oil is extracted from the extraction port at the bottom of the control valve group 9, the hydraulic oil will first pass through the filtration of the filter plate 705 and enter the control valve group 9. When the hydraulic station is working, the oil temperature inside the oil tank 1 is monitored in real time through the monitoring probe 203. When the temperature inside the oil tank 1 is too high, the refrigerator 303 and the cooling fan 304 are started, and the refrigerator 303 drives the cooling pipe 301 to work, and cooperates with the refrigerator 303 to exchange heat with the oil tank 1 to reduce the oil temperature inside the oil tank 1. And when the oil tank 1 is working, the vibration generated will be transmitted to the connecting rod 401. When the connecting rod 401 receives the force transmitted by the vibration of the oil tank 1, it will drive the moving block 402 to move together. At this time, the moving block 402 exerts a force on the damping rod 403, and the wedge block 1 501 on the front and rear sides of the moving block 402 will also move along the wedge block 2 502, so that the wedge block 2 502 moves along the spring 504 and squeezes the sliding rod 503. Through the contraction of the sliding rod 503 and the damping rod 403 and the provision of reaction force, the vibration force transmitted by the oil tank 1 can be absorbed in multiple directions, thereby reducing the noise generated when the hydraulic station is working.
