The electric motor 51 drives the main hydraulic pump 53 and the auxiliary hydraulic pump 54, thereby controlling the centrifugal pump motor to rotate and draw water, controlling the hydraulic rotary valve 71 and the pump truck traveling device 11. The main pipeline is divided into two lines, one connecting to the main pipeline and the other connecting to the electric regulating valve 75 and returning to the water tank. By finely adjusting the opening of the electric regulating valve 75, the output flow and pressure changes can be controlled. The control box 33 and the remote operation box 34 in the system have display functions for inlet pressure, outlet pressure, outlet flow, motor temperature, electric regulating valve opening, etc.

[0044] It also has a fault indication and alarm function;

[0045] The chassis assembly 1 is mainly composed of a walking device 11, a track device 12, and a frame welded 13. The function of the chassis assembly 1 is to install various components of the pump truck. It can achieve a free walking speed of 20m / min and a climbing ability of ±20°.

[0046] The control panel 2 mainly consists of a load multi-way valve group 21, a control frame 22, a display pressure gauge 23, a flow meter box 24, and an emergency stop button 25. It can display the hydraulic oil pressure, including the main hydraulic pump, auxiliary hydraulic pump, and centrifugal motor oil pressure.

[0048] The radiator assembly 4 consists of a water-cooled radiator 42 and a bracket 41, which dissipates heat from the hydraulic oil. One channel at the top is a water channel, and the other is an oil channel. The water channel carries away the heat from the oil channel through the radiator, preventing the oil channel temperature from rising continuously.

[0049] The hydraulic pump station 5 consists of an electric motor 51, a first coupling 52, a main hydraulic pump 53, and an auxiliary hydraulic pump 54. The hydraulic pump station 5 is the power source of the pump truck, converting electrical energy into hydraulic energy (pressurized oil). The electric motor 51 drives the oil pump to rotate through the first coupling 52. The oil pump draws oil from the oil tank and outputs pressurized oil. The high-pressure oil output by the main hydraulic pump 53 powers the centrifugal pump motor to rotate, which in turn draws water from the inlet to power the high-pressure plunger pump 63, providing power to the traveling device 11 so that the equipment can move.

[0050] The main pump assembly 6 consists of a water-cooled motor 61, a second coupling 62, a high-pressure plunger pump 63, and a pump with a radiator 64. The water-cooled motor 61 drives the high-pressure plunger pump 63 to generate high-pressure liquid at the outlet, which can provide a maximum working flow rate of 340L / min and a maximum working pressure of 50MPa.

[0051] The pipeline assembly 7 is divided into high-pressure pipeline and low-pressure pipeline. The high-pressure pipeline mainly consists of a plug valve 71, a check valve 72, a pipeline 74, an electric regulating valve 75, and a flow transmitter 76. The high-pressure pipeline comes out of the high-pressure plunger pump 63, passes through the check valve 72 and splits into two paths. One path returns to the water tank through the electric regulating valve 75, and the other path leads to the end working area of ​​the equipment.

[0052] The low-pressure pipeline consists of low-pressure pipe 77 and low-pressure transmitter 73. Low-pressure pipe 77 is located on the inlet side of high-pressure plunger pump 63 and mainly consists of hydraulic motor, centrifugal pump, filter, low-pressure pump inlet pipeline, motor water-cooling pipeline, and low-pressure transmitter 73. After passing through the centrifugal pump, the inlet pipeline splits into two paths: one enters high-pressure plunger pump 63, and the other connects to low-pressure transmitter 73 and filter via a hose, and then enters the water-cooled motor via a hose to provide cooling for the motor.

[0053] During the operation of the pump truck, the hydraulic oil tank 8 converts the electrical energy of the motor into hydraulic energy (pressurized oil) and serves as a storage unit. The total volume of the oil tank is 224L. The integrated valve group 84 is used to control the oil pressure of the centrifugal pump hydraulic motor and the auxiliary hydraulic pump 54.

[0054] The working principle of the hydraulic fracturing pump truck provided by this utility model is as follows:

[0055] Power supply: The electric motor 51 in the hydraulic pump station 5 drives the main hydraulic pump 53 and the auxiliary hydraulic pump 54 through the first coupling 52, converting electrical energy into hydraulic energy and outputting pressurized oil; the high-pressure oil output by the main hydraulic pump 53 provides power to the centrifugal pump motor, making it rotate to draw water, and providing the water required for the high-pressure plunger pump 63 to work; at the same time, the high-pressure oil also provides power to the traveling device 11, realizing the movement of the pump truck; the water-cooled motor 61 drives the high-pressure plunger pump 63 to work, so that high-pressure liquid is generated at the pump truck outlet, which can provide a maximum working flow rate of 340L / min and a maximum working pressure of 50MPa;

[0056] Flow and pressure regulation: The main pipeline is divided into two branches. One branch connects directly to the main pipeline to the end working area of ​​the equipment, and the other branch connects to the electric regulating valve 75 and returns to the water tank. By finely adjusting the opening of the electric regulating valve 75, the output flow and pressure can be controlled. When it is necessary to increase the flow and pressure, the opening of the electric regulating valve 75 is reduced, which reduces the bypass flow to the water tank and increases the flow and pressure in the main pipeline. Conversely, the opening of the electric regulating valve 75 is increased, which reduces the flow and pressure in the main pipeline. This regulation method does not change the pump speed, which effectively reduces costs compared to the traditional method of using a frequency converter to change the pump speed.

[0057] Equipment Control and Monitoring: The soft starter 31 and electromagnetic starter 32 in the control system 3 are used to start the equipment; the operator can remotely control the equipment to start, stop and other operations through the remote operation box 34; the control box 33 and the remote operation box 34 have display functions such as inlet pressure, outlet pressure, outlet flow, motor temperature, and electric regulating valve opening, and can also issue prompts and alarms when the equipment malfunctions, so that the operator can keep abreast of the equipment operating status and ensure the safe and stable operation of the equipment;

[0058] Heat dissipation and cooling: The water-cooled radiator 42 of radiator assembly 4 dissipates heat from the hydraulic oil. During the heat dissipation process, water and oil flow through the water-cooled radiator 42 respectively. The water carries away the heat from the oil, preventing the hydraulic oil temperature from becoming too high and ensuring the normal operation of the hydraulic system. A portion of the water in the low-pressure pipe 77 enters the water-cooled motor 61 to provide cooling and ensure stable motor operation.

[0059] Hydraulic oil storage and management: The hydraulic oil tank 8 stores hydraulic oil during the operation of the pump truck, with a total tank volume of 224L; the integrated valve group 84 is used to control the oil pressure of the centrifugal pump hydraulic motor and the auxiliary hydraulic pump 54 to ensure the normal operation of related components; the return oil filter 83 filters the return oil to maintain the cleanliness of the hydraulic oil.

[0060] Compared with related technologies, the hydraulic fracturing pump truck provided by this utility model has the following beneficial effects:

[0061] The hydraulic pump station 5, main pump assembly 6, and pipeline assembly 7 work together to change the outlet flow rate and pressure by adjusting the bypass opening during operation, without changing the pump speed. Compared with the traditional method of using a frequency converter to change the pump speed, this effectively reduces costs. Furthermore, the electric regulating valve 75 in the pipeline assembly 7 can control the output flow rate and pressure changes. Different openings of the electric regulating valve 75 result in different output pressures, enabling continuous output of multiple pressures to meet the pressure requirements of different operations.

[0062] The tracked layout of the chassis assembly 1, combined with the walking device 11 and track device 12, can adapt to different roadway construction environments in coal mines. Furthermore, operators can remotely operate the system via the remote control box 34, eliminating the need for on-site human intervention during fracturing, thus reducing the number of personnel on-site and lowering labor intensity. Meanwhile, the control box 33 and remote control box 34 in the control system 3 have display functions for inlet pressure, outlet pressure, outlet flow, motor temperature, and the opening degree of the electric regulating valve 75, and also have fault indication and alarm functions, improving the safety of on-site operations.

[0065] Specifically, the second embodiment of this application provides a hydraulic fracturing pump truck that differs in that the hydraulic fracturing pump truck further includes two sliding frames 9 and a protective plate 91. The two sliding frames 9 are slidably connected to both sides of the protective plate 91, and both sliding frames 9 are fixedly installed on the side of the oil tank body 86. The protective plate 91 is provided with the side of the liquid level thermometer 87, and a counterweight block 92 is fixedly installed at the bottom of the side of the protective plate 91. An observation window 93 is fixedly installed inside the protective plate 91.

[0066] When in use, the user can also observe the value on the liquid level thermometer 87 through the observation window 93, which is made of acrylic sheet.

[0067] The working principle of the hydraulic fracturing pump truck provided by this utility model is as follows:

[0068] When in use, when the user needs to observe the value on the liquid level thermometer 87, the user can hold the counterweight 92 and move it upward, so that the protective plate 91 slides on the inner side of the slide frame 9. Then the user can observe the setting on the liquid level thermometer 87 located on one side of the protective plate 91.

[0069] After the observation is completed, the user releases the counterweight 92. At this time, the counterweight 92 will move the protective plate 91 downward, so that the protective plate 91 is on the side of the liquid level thermometer 87, thereby blocking and protecting the liquid level thermometer 87.

[0070] Compared with related technologies, the hydraulic fracturing pump truck provided by this utility model has the following beneficial effects:

[0071] The sliding frame 9, protective plate 91, counterweight 92 and observation window 93 work together to ensure that the protective plate 91 is positioned on the side of the liquid level thermometer 87 during use, thus protecting the liquid level thermometer 87.
