Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps, in particular to an oil pump with a pressure relief valve assembly. Background Art

[0002] Engine oil is the lubricating oil of the engine, which can lubricate and reduce wear, assist in cooling and reducing temperature, seal and prevent leakage, prevent rust and corrosion, and reduce shock and buffer. It is known as the "blood" of mechanical equipment, and the function of the oil pump is to increase the engine oil to a certain pressure and then force it to the moving surfaces of various parts of the engine to deliver "blood" to the mechanical equipment. The oil pump has a simple structure and is easy to operate. It can work normally as long as the power supply or start handle is turned on as required. The operation process is simple and easy to use. In addition, the oil pump has a strong delivery capacity and can effectively transport high-viscosity fluids, high-temperature and high-pressure media, particulate matter and other media with large differences in viscosity and properties. It can meet the needs of different industries for liquid transportation. In order to adjust and control the oil pressure in the main oil channel of the oil pump, a pressure relief valve is usually installed on the oil pump. The pressure relief valve can automatically open or close when the oil pump reaches the upper limit of the safe working pressure of the system, thereby reducing the working pressure and ensuring the safety of the system.

[0003] Traditionally, the oil pump has a large mass. When the oil pump needs to be transferred or moved during use, the operation will be very laborious and inconvenient, and there will be high requirements on the operator's strength. It is also difficult to adjust the oil pump.

[0004] Therefore, it is necessary to provide a new oil pump with a pressure relief valve assembly to solve the above technical problems. Utility Model Content

[0022] In order to facilitate the fixation between the mounting plate 2 and the workbench 1, thereby ensuring the stability of the oil pump 3 on the workbench 1, four positioning blocks 16 are fixedly installed on the top of the workbench 1, and the four positioning blocks 16 are all U-shaped and distributed in a rectangular array. The four positioning blocks 16 are grouped in pairs and are respectively located on both sides of the mounting plate 2. Two fixing blocks 17 are fixedly installed on both sides of the mounting plate 2, and two threaded sleeves 18 are rotatably installed on the four fixing blocks 17. Two threaded sleeves 18 are each provided with two sections of internal threads with opposite rotation directions.

[0023] In order to limit the movement tendency of the two sliders 14 and the four connecting blocks 20 and increase the stability of the two sliders 14 and the four connecting blocks 20, two longitudinal rods are fixedly installed on the top of the two sliders 14, and strip plates are rotatably sleeved on the two screw rods 12.

Limiting blocks are fixedly installed on the ends of the four transverse rods away from the four connecting blocks 20.

[0024] The working principle of the oil pump with pressure relief valve assembly provided by the utility model is as follows:

[0025] During the use of the oil pump 3, when the oil pump 3 needs to be moved or transferred, the two threaded sleeves 18 can be rotated successively. During the rotation of the two threaded sleeves 18, the four screw rods 19 will gradually move outward in the two threaded sleeves 18 due to the restriction of the four transverse rods. The four screw rods 19 slide while driving the four connecting blocks 20 and the four transverse rods. The connection between the four connecting blocks 20 and the four positioning blocks 16 will be gradually released. At this time, the mounting plate 2 and the oil pump 3 are in an adjustable state.

[0026] Then, the two screw rods 12 are rotated successively. During the rotation of the two screw rods 12, they will come into rotational contact with the two circular blocks 13. Due to the restriction of the four longitudinal rods, the screw rods 12 will generate driving force on the two sliders 14, so that the two sliders 14 gradually move upward, and the two sliders 14 drive the four circular blocks 15 to gradually slide out of the corresponding four circular slots 7. At this time, the four circular blocks 6 will also be fixed. Then, the mounting plate 2 is lifted from the workbench 1 with the help of external force. After the mounting plate 2 is lifted to a suitable height, the two connecting arms 8 are rotated. Under the influence of the four connecting rods 10, the four The connecting arms 8 will move at the same time, and the four connecting arms 8 will be rotated and adjusted from the initial horizontal distribution to a longitudinal horizontal state. At this time, the other four circular slots 7 will be aligned with the four circular blocks 15, and then the two screws 12 will be rotated in the opposite direction to make the four circular blocks 15 re-insert into the corresponding four circular slots 7, so as to re-fix the four connecting arms 8. At this time, the four rollers 9 will be distributed vertically downward, and then the mounting plate 2 will be slowly lowered to support the ground with the four rollers 9, and then the oil pump 3 can be pushed to move freely, eliminating the step of carrying the oil pump 3, which is relatively more labor-saving.

[0027] Compared with the related art, the oil pump with a pressure relief valve assembly provided by the utility model has the following beneficial effects:

[0028] In the utility model, the workbench 1 and the mounting plate 2 are fixed by four positioning blocks 16 and four connecting blocks 20. The connection between the four positioning blocks 16 and the four connecting blocks 20 can be controlled as needed by controlling the rotation direction of the two threaded sleeves 18, which facilitates the disassembly and assembly of the mounting plate 2. The positions of the four rollers 9 and the four connecting arms 8 are fixed by four circular clamping blocks 15. By rotating two screw rods 12, the heights of the four blocks 15 can be adjusted, which is convenient for adjusting the positions of the four rolling paths 9 and ensuring the stability of the positions of the four rollers 9. With the use of the four rollers 9, the effort required for the oil pump 3 to move can be reduced, thereby enabling the oil pump 3 to be moved relatively effortlessly.
