Description

Technical Field

[0001] The utility model relates to the technical field of electric ultra-high pressure pump devices, and particularly relates to an electric ultra-high pressure pump. Background Technique

[0002] An electric ultra-high pressure pump is an important industrial device. It relies on the drive of an electric motor and accumulates pressure through specific mechanisms (such as plungers, pistons, etc.) inside the pump body to generate ultra-high pressure water flow or other fluids. The working principle of the electric ultra-high pressure pump is to convert the mechanical energy of the electric motor into the pressure energy of the liquid. Inside the pump body, the electric motor drives the piston or plunger to perform reciprocating motion. When the piston or plunger moves backward, the pump body sucks in the medium from the water inlet; when it moves forward, it compresses and pushes the medium towards the outlet, thus generating high-pressure water flow.

[0003] During the use of the electric ultra-high pressure pump, it has many advantages, such as high pressure output to meet high-pressure requirements; excellent pressure-holding ability and various variable modes to adapt to different working conditions; compact structure for easy installation and use, etc. However, it also has certain disadvantages, such as relatively high manufacturing cost, resulting in usually high market prices; it may generate relatively large noise and vibration under high-pressure operating conditions, which has a certain impact on the working environment, etc. Therefore, comprehensive consideration needs to be made according to specific application scenarios and requirements when selecting and using it.

[0004] Currently, when using the electric ultra-high pressure pump, it is necessary to first detect the equipment to ensure its normal use, then turn on the power switch, adjust parameters such as the required pressure and flow rate, and slowly open the output valve so that the medium starts to flow out, then the electric ultra-high pressure pump can be used.

[0005] However, after the use of the electric ultra-high pressure pump is completed, the situation where one end of the oil outlet pipe is disconnected from the external pipeline will occur, so that one end of the oil outlet pipe is in an open state, which will cause dust and the like to enter the inside of the oil outlet pipe, affecting the purity of the medium inside the equipment and reducing the service life of the parts inside the equipment. Content of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide an electric ultra-high pressure pump to solve the technical problem that after the use of the electric ultra-high pressure pump is completed, the situation where one end of the oil outlet pipe is disconnected from the external pipeline will occur, so that one end of the oil outlet pipe is in an open state, which will cause dust and the like to enter the inside of the oil outlet pipe, affecting the purity of the medium inside the equipment and reducing the service life of the parts inside the equipment.

[0007] To achieve the above object, the present utility model provides the following technical solution: An electric ultra-high pressure pump, including a high-pressure pump main body, one end of the high-pressure pump main body is provided with an oil outlet pipe, an internal thread is provided in the oil outlet pipe, and a pressure gauge is installed near the oil outlet pipe end of the high-pressure pump main body. It is characterized in that: a fixing ring is fixedly connected to the outer surface of the oil outlet pipe, a connecting pipe is slidably connected to the surface of the fixing ring, and the fixing ring and the connecting pipe are connected by a plurality of springs. One end of the connecting pipe is fixedly connected with two groups of connecting pieces, a rotating shaft is rotatably connected between each group of connecting pieces, a sealing plate is fixedly connected to the outer surface of each rotating shaft, and torsion springs are provided between both ends of each rotating shaft and the corresponding connecting pieces.

[0008] By adopting the above technical solution, when the equipment is in use, the connecting pipe can be driven to slide on the outer surface of the oil outlet pipe, so as to generate a squeezing force on the sealing plate through the outer wall of the oil outlet pipe, causing the sealing plate to rotate outwards until one end of the oil outlet pipe is opened and can be connected to an external pipeline for use. Then, the connecting pipe is released. At this time, the spring drives the connecting pipe to reset. And because one end of the oil outlet pipe is connected to the external pipeline, the sealing plate has no room for rotation and thus remains in place. At the same time, after use, the connecting pipe is driven to move again. After the external pipeline is separated from the oil outlet pipe, the connecting pipe is released to make it reset through the spring again. And because there is no connection object at one end of the oil outlet pipe at this time, the sealing plate can be driven to reset by the torsion spring until the sealing plate blocks one end of the oil outlet pipe, which can prevent external air, dust and other impurities from entering the interior of the oil outlet pipe, help ensure the purity of the medium, make its flow smoother, thereby improving work efficiency, and can reduce the blockage of internal parts by impurities, etc., and is convenient for extending the service life.

[0009] The present utility model is further provided that: a group of chutes are provided on the inner wall of the connecting pipe, a slider that fits with the chute is slidably connected in each chute, and each slider is fixedly connected to the outer surface of the fixing ring. The slider is provided with a "T" - shaped structure.

[0010] By adopting the above technical solution, the connecting pipe can be limited, preventing it from falling off the oil outlet pipe and affecting the use of the equipment.

[0011] The present utility model is further provided that: sleeves are fixedly connected to the four corners of the bottom of the high-pressure pump main body, threaded rods are threadedly connected to the bottom of each sleeve, and fixing plates are fixedly connected to the bottom of each threaded rod.

[0012] By adopting the above technical solution, the threaded rod can move within the sleeve, thereby flexibly adjusting the position and height of the fixing plate, facilitating the better installation of the high-pressure pump main body. At the same time, through the sleeves, threaded rods and fixing plates at the four corners of its bottom, stable support can be provided for the high-pressure pump main body, ensuring the stability and safety of the equipment operation.

[0013] The present utility model is further configured such that an oil drain port is provided at one end of the high-pressure pump main body, and a sealing cover is movably connected to one end of the oil drain port. An oil level gauge is provided at one end of the high-pressure pump main body.

[0014] By adopting the above technical solution, the lubricating oil in the high-pressure pump main body can be discharged through the oil drain port, facilitating the regular replacement of new oil and reducing the accumulation of impurities in the high-pressure pump main body. At the same time, the oil level gauge can monitor the oil level in the high-pressure pump main body in real time, avoiding the dry grinding phenomenon of the pump body due to lack of oil and protecting the pump body components from damage.

[0015] The present utility model is further configured such that a protective frame is welded to the top of the high-pressure pump main body, and heat dissipation openings are provided on both sides of the high-pressure pump main body.

[0016] By adopting the above technical solution, the protective frame can play a certain protective role for the high-pressure pump main body, and the cross beam at the top of the protective frame can be lifted to change the position of the high-pressure pump main body. At the same time, the heat dissipation openings can timely discharge the heat in the high-pressure pump main body for effective heat dissipation, preventing the pump body from overheating due to heat accumulation and affecting the use.

[0017] The present utility model is further configured such that a rubber layer is provided on the outer surface of each sealing plate.

[0018] By adopting the above technical solution, due to the elasticity and sealing property of the rubber material, it can be made to fit with one end of the oil outlet. Therefore, when the high-pressure pump main body is not in use, it can prevent external dust and other impurities from entering the interior and affecting the use.

[0019] The present utility model is further configured such that positioning holes are provided at the four corners of each fixing plate.

[0020] By adopting the above technical solution, fixing parts such as bolts can be installed in the positioning holes to complete the fixation of the fixing plate, thereby realizing the fixation of the high-pressure pump main body and ensuring that the high-pressure pump main body will not shake or displace during operation, which helps to increase the stability and safety during the equipment operation.

[0021] In summary, the present utility model mainly has the following beneficial effects:

[0022] In the present utility model, an oil connection pipe is slidably connected to the surface of an oil outlet pipe, and one end of the connection pipe is rotatably connected to a set of sealing plates. Therefore, when the device is not in use, the sealing plates can block one end of the oil outlet pipe through a torsion spring, thus preventing impurities such as external air and dust from entering the interior of the device.

Detailed Embodiment

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] An electric ultra-high pressure pump, as Figures 1-5 shown, includes a high-pressure pump main body 1. An oil outlet pipe 8 is provided at one end of the high-pressure pump main body 1. An internal thread 9 is provided inside the oil outlet pipe 8, and the oil outlet pipe 8 can be connected to an external pipe through the internal thread 9 to use the device. A pressure gauge 7 is installed at the end of the high-pressure pump main body 1 close to the oil outlet pipe 8, so that the working pressure of the high-pressure pump main body 1 can be monitored in real time to ensure the safe operation of the device.

[0032] Meanwhile, a protective frame 2 is welded and connected to the top of the high-pressure pump main body 1. The protective frame 2 can play a certain protective role for the high-pressure pump main body 1. At the same time, the cross beam at the top of the protective frame 2 can be used as a handle, and the high-pressure pump main body 1 can be lifted by it to change its position. Heat dissipation openings 3 are arranged on both sides of the high-pressure pump main body 1, which can timely discharge the heat in the high-pressure pump main body 1 for effective heat dissipation, preventing heat accumulation from causing the pump body to overheat and affecting its use. And an oil drain port 4 is arranged at one end of the high-pressure pump main body 1, and a sealing cover 5 is movably connected to one end of the oil drain port 4. The lubricating oil in the high-pressure pump main body 1 is discharged through the oil drain port 4, so as to achieve the function of regularly replacing the new oil. An oil level gauge 6 is arranged at one end of the high-pressure pump main body 1 to realize real-time monitoring of the oil level in the high-pressure pump main body 1, avoiding dry grinding caused by lack of oil and protecting the components of the high-pressure pump main body 1 from damage.

[0033] Subsequently, a fixing ring 10 is fixedly connected to the outer surface of the outlet pipe 8. A connecting pipe 11 is slidably connected to the surface of the fixing ring 10. The fixing ring 10 and the connecting pipe 11 are connected by a plurality of springs 18. When driving the connecting pipe 11 to slide, the springs 18 will be compressed. Therefore, after the driving force disappears, the connecting pipe 11 can be driven to reset by the springs 18. Two groups of connecting pieces 14 are fixedly connected to one end of the connecting pipe 11. A rotating shaft 15 is rotatably connected in the middle of each group of connecting pieces 14. A sealing plate 16 is fixedly connected to the outer surface of each rotating shaft 15, so that the sealing plate 16 can rotate through the rotating shaft 15. And a rubber layer is arranged on the outer surface of each sealing plate 16. Due to the elasticity and sealing property of the rubber material, it is made to fit with one end of the outlet pipe 8. A torsion spring 17 is arranged between both ends of each rotating shaft 15 and the corresponding connecting piece 14. Therefore, after the sealing plate 16 is rotated and opened by an external force, it can return to its original state when the external force disappears through the torsion spring 17, thereby blocking one end of the outlet pipe 8. Then, external air, dust and other impurities can be prevented from entering the equipment interior, which helps to ensure the purity of the medium, makes its flow smoother, thereby improving the working efficiency, and can reduce the blockage of internal parts by impurities, etc., facilitating the extension of the service life.

[0034] Wherein, a group of sliding grooves 12 are arranged on the inner wall of the connecting pipe 11. A slider 13 that fits with the sliding grooves 12 is slidably connected in each sliding groove 12. Each slider 13 is fixedly connected to the outer surface of the fixing ring 10. Then, when the connecting pipe 11 slides on the outer surface of the outlet pipe 8, the slider 13 can slide in the sliding groove 12, thereby playing a limiting role on the connecting pipe 11. The slider 13 is set in a "T" shape structure, which can increase the stability during sliding.

[0035] Furthermore, sleeves 19 are fixedly connected to the four corners of the bottom of the high-pressure pump main body 1. A threaded rod 20 is threadedly connected to the bottom of each sleeve 19, and a fixing plate 21 is fixedly connected to the bottom of each threaded rod 20. Thus, the high-pressure pump main body 1 can be provided with stable support through the sleeves 19, threaded rods 20 and fixing plates 21, enhancing the stability and safety of the equipment during operation. At the same time, the position of the fixing plate 21 can be flexibly adjusted to facilitate the installation of the high-pressure pump main body 1. Positioning holes 22 are provided at the four corners of each fixing plate 21. The high-pressure pump main body 1 can be fixed by installing fixing parts, such as bolts, in the positioning holes 22, which helps to increase the stability and safety of the equipment during operation.
