Description

Technical Field

[0001] This utility model is a high-pressure pump testing device for an automobile engine cleaning machine, belonging to the field of high-pressure pump technology. Background Technology

[0002] High-pressure pumps are devices that provide high-pressure power for high-pressure jet grouting cement slurry. They are used for foundation reinforcement in buildings, highways, and other applications. They can also be used for high-pressure water jet-assisted rock breaking and coal extraction, fluid supply for underground hydraulic supports, pumping high-pressure water for anchored hydraulic expansion metal anchors, and dredging and cleaning of large underground pipelines.

[0003] However, in the existing high-pressure pump assembly, when changing the water inlet for different models, the water pipe needs to be replaced, which increases the difficulty of replacement and easily leads to water leakage at the water inlet. During the testing of the high-pressure pump of the cleaning machine, external mud and sand can easily enter the pump body through the water inlet, thus affecting the use of the high-pressure pump of the cleaning machine. There is an urgent need for a high-pressure pump testing device for car engine cleaning machines to solve the above problems. Utility Model Content

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] Please see Figures 1-14 This utility model provides a technical solution: a high-pressure pump testing device for an automotive engine cleaning machine, comprising a high-pressure pump assembly 1 and a crankcase 2. A connecting pad 3 is fixedly connected to the upper end of the high-pressure pump assembly 1. A mating plate 5 is fixedly connected to both the front and rear ends of the crankcase 2. Two second structural positioning holes 6 are provided at the front and rear ends of both mating plates 5. A mounting plate 12 is provided at the front end of one of the mating plates 5, and a connecting pipe 11 is fixedly connected to the front end of the mounting plate 12. Four first bolt rods 7 are fixedly connected to the front end of one of the mating plates 5 through threaded holes. Three cylinder holes 8 are provided at both the upper and lower ends of the crankcase 2. Two third structural positioning holes 10 are provided at the lower end of the crankcase 2, and eight second... A mounting ring 15 is fixedly connected to the inner circumference of the bolt rod 9 and the connecting pipe 11. A filter screen 14 is installed inside the mounting ring 15. Two sets of fixing components are provided between the filter screen 14 and the mounting ring 15. One set of fixing components includes a first slot 19, a second slot 21, a mounting seat 17, and a rotating head 18. The first slot 19 is opened in the docking plate 5, the second slot 21 is opened at the lower end of the filter screen 14, the mounting seat 17 is rotatably connected to the second slot 21 and the first slot 19, and the rotating head 18 is fixedly connected to the upper end of the mounting seat 17. This design solves the problem that when the high-pressure pump assembly 1 of the original device is used, it is necessary to replace the water pipe when changing the water inlet for different models, which increases the difficulty of replacement and easily leads to water leakage at the water inlet.

[0032] As the first embodiment of this utility model: The upper end of the crankcase 2 is provided with multiple first structural positioning holes 4. These first structural positioning holes 4 on the crankcase 2 allow the crankcase 2 to be fixed to the high-pressure pump assembly 1 by bolts. The two docking discs 5 are concentric. By connecting open pipes of different structures to the docking discs 5 and then blocking one of them, the position of the crankcase 2 can be directly changed when connecting to different types of water inlets. The lower end of the filter screen 14 is fixedly connected to two positioning rods 16. The upper end of the docking disc 5 is provided with two positioning grooves 20. The two positioning rods 16 are slidably connected to the two positioning grooves 20 respectively. The positioning rods 16 installed at the bottom of the filter screen 14, by sliding into the positioning grooves 20, assist the fixing assembly in positioning the filter screen 14 within the docking disc 5. A sealing ring 13 is provided between the mounting plate 12 and one of the mating plates 5. The sealing ring 13 between the mounting plate 12 and the mating plate 5 can increase the sealing performance between the mating plate 5 and the connecting pipe 11, and prevent water leakage at the connection between the mounting plate 12 and the mating plate 5 when water is introduced into the crankcase 2. The mounting plate 12 is connected to two of the second structural positioning holes 6. By connecting with the second structural positioning holes 6, the mounting plate 12 can be positioned and installed on the surface of the mating plate 5.

[0033] As a second embodiment of this utility model: When using the crankcase 2, firstly, fix one end of the connecting plate 5 with the connecting pipe 11 using the first bolt rod 7, connect the connecting pipe 11 to the water inlet, and then control the high-pressure pump assembly 1 to discharge water. This is used to determine whether the speed, pressure, flow rate, and sealing of the motor in the high-pressure pump assembly 1 are up to standard. When the crankcase 2 is connected to different water inlets, it can be removed and rotated 180° to be installed on the high-pressure pump assembly 1, so that the crankcase 2 can be adapted to different types of water inlets, and at the same time, the ease of installation is increased. After a long time, the filter screen 14 will accumulate in the connecting pipe 11. Excessive sediment accumulation can affect the filtration effect of the connecting pipe 11. To fix the filter screen 14 in the mounting ring 15, the connecting pipe 11 can be removed, and the rotating head 18 can be rotated to loosen the first slot 19 and the second slot 21 of the retainer 17. Then, the rotating head 18 can be pulled to separate the filter screen 14 from the mounting ring 15. When replacing the filter screen 14, the positioning rod 16 can be slid into the positioning groove 20, and the first slot 19 and the second slot 21 can be aligned. Then, the retainer 17 can be inserted into the first slot 19 and the second slot 21, and the rotating head 18 can be rotated to lock the retainer 17 into the first slot 19 and the second slot 21.
