Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection equipment, in particular to a vacuum degree detection system for an oil well pump. Background Art

[0002] One of the main functions of automobile engine oil is to lubricate the engine to reduce friction and wear between parts. Failure to change the engine oil for a long time will cause it to deteriorate and fail, which will greatly reduce the lubricating effect of the engine oil. This will directly affect the performance and life of the engine and increase the degree of wear of the engine. When changing the automobile engine oil, an oil pump is needed to extract the oil in the chassis;

[0003] An oil pump is usually composed of an air pump and an oil pot. The air pump is tightly combined with the oil pot. The gas in the oil pot is discharged by pumping the air pump, so that a negative pressure is formed in the oil pot, and the automobile oil that needs to be replaced is sucked into the oil pot through the oil suction port, thereby completing the purpose of replacing the automobile oil. If the air tightness of the oil pump does not meet the standard, the oil replacement efficiency will be reduced, and even oil leakage will be caused. In order to ensure that the air tightness of the oil pump meets the standard, we propose an oil pump vacuum detection system to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a vacuum degree detection system for an oil well pump, so as to solve the problem of whether the air tightness of the oil well pump reaches the standard.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vacuum degree detection system for an oil well pump, comprising a detection platform, a vacuum gauge and a gas tank, the detection platform is used to place the oil well pump, the vacuum gauge is arranged at the oil suction port of the oil well pump, the gas tank is arranged on the table top of the detection platform, a mounting frame is arranged at the upper end of the detection platform, and a plurality of groups of detection equipment are arranged at the end of the mounting frame away from the detection platform, each group of detection equipment comprises a cylinder, a mounting block and a hook, the cylinder is arranged at the end of the mounting frame away from the table top of the detection platform, and the output end of the cylinder passes through the mounting frame, the mounting block is arranged at the end of the output end, the hook is symmetrically arranged at the end of the mounting block close to the table top of the detection platform, and the hook is clamped with the handle of the oil well pump, and the table top of the detection platform is provided with a fixing component corresponding to each group of detection equipment.

[0006] The beneficial effects of this program are:

[0007] 1. Fix the bottom of the oil pump through the fixing assembly, and then use the cylinder to reciprocate the suction cylinder of the oil pump to discharge the air in the oil pump, so that a certain vacuum environment is formed inside the oil pump. When the cylinder stops working, the air pressure in the oil pump tends to be stable. At this time, the vacuum gauge located at the oil suction port of the oil pump detects the air pressure change in the oil pot. If the index of the vacuum gauge is stable, it means that the air tightness of the oil pump meets the standard, otherwise it means that the air tightness of the oil pump does not meet the standard.

[0017] Preferably, as an improvement, the solenoid valve is electrically connected to an electric control box.

[0018] The beneficial effect is that the electric control box can program and control the action of the solenoid valve, thereby controlling the reciprocating times of the cylinder output end according to actual conditions.

[0019] Preferably, as an improvement, the surface of the testing platform is symmetrically provided with positioning rings, and each positioning ring is configured as an arc-shaped ring matching the bottom of the oil well pump.

[0020] The beneficial effect is that the positioning ring allows the staff to quickly place the oil pump to the test position, thereby increasing the detection efficiency.

The oil pump 2 comprises an air pump and an oil pot. The upper end of the oil pot is tightly combined with the air pump. The bottom of the oil pot is in a truncated cone shape. A handle is connected to the upper end of the air pump. An oil suction port is opened on the outer side of the oil pot. The vacuum gauge 4 is detachably mounted at the oil suction port of the oil pump 2. An air outlet pipe 10 and two air return pipes 11 are connected to the upper end of the air tank 3. A mounting frame 5 is fixedly mounted on the upper end of the detection platform 1. Two groups of detection equipment are symmetrically fixedly mounted on the upper end of the mounting frame 5. Each group of detection equipment comprises a cylinder 6, a mounting block 7 and a hook 8. The cylinder 6 is fixedly mounted on the upper end of the mounting frame 5, and the output end of the cylinder 6 slides through the mounting frame 5. The first air port and the second air port are respectively provided on the lower two sides, and the first air ports are connected with a first bifurcated pipe 12, and the second air ports are connected with a second bifurcated pipe 13. A solenoid valve 9 is fixedly installed in the middle of the upper end of the mounting frame 5. The solenoid valve 9 uses a two-position five-way solenoid valve 9. The solenoid valve 9 is electrically connected to an electric control box, and the action of the solenoid valve 9 is programmed and controlled by the electric control box. Of course, the lifting and lowering of the two cylinders 6 can also be controlled separately. The air outlet pipe 10, the first bifurcated pipe 12, the second bifurcated pipe 13 and the two return air pipes 11 are all connected to the solenoid valve 9. The upper end of the mounting block 7 is rotatably connected with a nut 18, and the nut 18 is fixedly connected to the output end of the cylinder 6 by a thread. Of course, the output end of the cylinder 6 can also be fixedly connected to the upper end of the mounting block 7 by welding. The lower end of the mounting block 7 is symmetrically fixedly installed with a hook 8, such as Figure 3 As shown, a stopper 20 is fixedly installed in the hook 8 near the mounting frame 5 by spot welding, and a fixing assembly corresponding to the two sets of detection equipment is fixedly installed on the upper end of the detection platform 1, and the fixing assembly includes a fixing block 14 symmetrically fixedly installed on the upper end of the detection platform 1, and the opposite ends of the two fixing blocks 14 are set as an inclined surface abutting against the bottom truncated cone of the oil well pump 2, and a positioning ring 19 is symmetrically fixedly installed on the upper end of the detection platform 1, and each positioning ring 19 is set as an arc ring matching the bottom truncated cone of the oil well pump 2;

[0030] The lower end of the mounting frame 5 is equipped with sliding components located on both sides of the two groups of test equipment.

Then, the two oil pumps 2 are pushed to the positioning block ring, and the round table at the bottom of the oil pump 2 is clamped between the two fixing blocks 14. At this time, the handle of the oil pump 2 is clamped on the hook 8. The staff activates the solenoid valve 9 to transport the gas in the gas tank 3 to the upper end of each cylinder 6 through the first bifurcated pipe 12, so that the output end of each cylinder 6 drives the mounting block 7 to move downward along the slide 16. At this time, the gas at the lower end of each cylinder 6 passes through the second bifurcated pipe 13. It flows through the solenoid valve 9 and returns to the gas tank 3. When the output end of the cylinder 6 extends to a certain length, the solenoid valve 9 controls the gas to be transported to the inside of each cylinder 6 through the second bifurcated pipe 13, so that the output end of each cylinder 6 contracts, and the gas in each cylinder 6 flows through the solenoid valve 9 through the first bifurcated pipe 12 and returns to the gas tank 3. This is repeated so that the output end of each cylinder 6 drives the mounting block 7 to perform reciprocating motion, thereby pulling the vacuum cylinder of the oil pump 2 through the hook 8 to discharge the internal air, making the internal part of the oil pump 2 in a negative pressure state, and then judging whether the air tightness of the oil pump 2 meets the standard through the reading of the vacuum gauge 4.
