[0002] A hydraulic station is a special power output device dedicated to the opening and plugging operations on long-distance oil and gas pipelines. It is connected to the corresponding opening machine or plugging device through hydraulic hoses to achieve the feeding and cutting of the opening machine or the feeding of the plugging device. It can also be connected to a clamping valve that uses a hydraulic cylinder to control the opening and closing of the gate of the clamping valve to achieve the opening and closing of the valve, thus completing the opening and plugging operations. It is an essential equipment for pipeline maintenance, repair and emergency operations.

[0003] In the past, most hydraulic stations used an electric motor to drive the hydraulic pump to operate the entire system. Since pipeline maintenance, repair and emergency operations are mostly carried out in the wild, this method requires a separate generator to supply power to the hydraulic station, which causes difficulties in the implementation of on-site operations. Moreover, it requires the site placement, hoisting operations and electrical wiring of two pieces of equipment, and the operation is complex.

[0004] In the maintenance, repair and emergency operations of oil and gas pipelines, in order to meet the increasingly required rapid emergency response, the integrity, integration and high adaptability to field working conditions of the equipment have become the key technical requirements of the equipment. The existing supporting hydraulic stations can no longer meet the usage requirements, so improvements need to be made to it. Content of the Utility Model

[0022] A shock-resistant pressure gauge 26 is provided on the side surface of the hoisting frame assembly 21 to display the pressures of the main system and the balance system.

[0023] The shock absorption device 22 includes a threaded cylinder 2204 fixedly connected to the lower end of the base 20. A screw rod 2203 is threadedly connected to the lower end of the threaded cylinder 2204. A protective shell 2202 is fixedly connected to the lower end of the screw rod 2203.

[0024] A plurality of shock absorption devices 22 are provided.

[0025] The working principle of the present utility model is as follows: The device is moved to a fixed position through the sling seats on the hoisting frame assembly 21, and the screw rod 2203 is rotated to move it up and down, driving the protective shell 2202 and the shock pad 2201 to move up and down, so as to enable the plurality of shock absorption devices 22 to reach different heights, and further facilitate placing the device on the pitted terrain.

[0026] Connect the pipeline. When driving the hole opener, the hydraulic hose is connected to the hole opener oil inlet, the hole opener oil return, and the hole opener oil drain ports on the present utility model. If connecting the clamping plate valve or the plugging cylinder, only the two oil pipes of the hole opener oil inlet and the hole opener oil return need to be connected.

[0027] Open the four operation doors of the diesel engine, turn on the battery switch. Before starting, the hydraulic system pressure needs to be adjusted to zero to achieve a light-load start of the diesel engine. Zero adjustment can be achieved by opening the plate ball valve 15 on the valve block 11 or adjusting the relief valve 16 in two ways.

[0028] Adjust the hydraulic system. The hydraulic adjustment mainly includes the adjustment of the main system pressure and the balance system pressure. After the diesel engine 4 starts successfully, close the plate ball valve 15 and the external output. Slowly rotate the handle of the main system relief valve 16 clockwise, and observe the main system pressure at all times. When the system pressure rises to the required pressure, the adjustment is completed, and tighten the locknut of the relief valve 16 handle. The balance system is the same. When the balance circuit is not used, open the balance ball valve 29 to unload the balance circuit. It is recommended to use the plate ball valve 15 to control the external output of the system. When the system does not have an external output, open the plate ball valve 15 to unload. When an external output is required, close the plate ball valve 15, and the oil can be externally output. The hydraulic oil is transported to the valve block 11 through the double gear pump 5. The relief valve 16 on the valve block 11 is used as a safety valve and to adjust the pressure of the main system. The hydraulic oil can directly return to the hydraulic oil tank housing 1 from the valve block 11 through the control of the relief valve 16. The plate ball valve 15 and the balance ball valve 29 mainly control the pressure output of the main system and the balance system. When the plate ball valve 15 is opened, the hydraulic oil directly returns to the tank through the plate ball valve 15. After the plate ball valve 15 is closed, the hydraulic oil will supply oil to the main system and the balance system through the valve block 11, drive the controlled equipment, and return oil through the return oil filter 12. At this time, after the relief valve 16 is adjusted for the first time, it does not need to be adjusted again.

[0029] Cool the hydraulic oil temperature. After the hydraulic station runs for a long time, the temperature of the hydraulic oil may be too high. At this time, it is necessary to turn on the cooling system to cool the oil temperature. Press the cooling start button, and the DC brushless fan 18 starts. Strong wind blows through the cooling oil pipe to reduce the oil temperature. The DC brushless fan 18 needs to be turned on when the diesel engine 4 is running. When the diesel engine 4 is in the stopped state, it can only be started for a short time to avoid exhausting the battery power and causing the diesel engine 4 to fail to start.

[0030] Speed regulation of the diesel engine 4. Increasing the speed of the diesel engine 4 can increase the output flow rate, making the hole opener have a faster speed. When connecting the clamp valve or the plugging cylinder, a smaller flow rate is required. At this time, the speed of the diesel engine 4 can be adjusted downward. Adjusting the speed of the diesel engine 4 mainly involves adjusting the diesel engine throttle.
