Problems solved by technology

[0005] The object of the present invention is to provide a leak detection device and leak detection equipment for a pump body. By installing and sealing the pump body on the leak detection table, inflating the cavity of the pump body, and using an air tightness detector to check the leakage in the cavity. The air pressure is detected to judge whether the pump body is leaking, and the original leak detection method is time-consuming and laborious, and the detection is inaccurate, which seriously affects the pass rate of the pump body in the factory.

Embodiment 1

[0085] Such as figure 1 As shown, a leak detection device includes a body 1 on which two sets of pump body leak detection devices are installed, which can work simultaneously to perform leak detection operations on two pump bodies 4 . .

[0086] Such as figure 2 with image 3 As shown, the leak detection device 6 includes a frame 5, a pressing mechanism 100, a sealing mechanism 7, an inflation detection mechanism 400 and an adjustment mechanism 1 600; the inflation detection mechanism 400 includes an air tightness detector 500.

[0087] The sealing mechanism 7 includes a sealing assembly 1 200 and a sealing assembly 2 300

[0088] The ports of the pump body 4 mainly include port one 41, port two 42, port three 43, port four 44, and port five 45, and the ports are on different sides.

[0089] The frame 5 is installed on the body 1, the bottom of the frame 5 is a leak detection platform, a positioning die 3 is installed on the leak detection table 2 by screws, and the press...

Embodiment 2

[0115] The technical scheme of this embodiment is substantially the same as that of Embodiment 1, because the models of the pump body are different, and the pump body 4 of this embodiment is as Figure 8 shown.

[0116] Therefore, a new sealing assembly 2300 is designed for this pump body model, and the specific scheme is as follows.

[0117] Such as Figure 9-Figure 12 As shown, the sealing assembly 2 300 includes a tooling plate 305 , a positioning mandrel 306 , a balancing mandrel 307 , an adjustment plate 308 , several springs 309 and a lock ring 310 that cooperates with the spring 309 .

[0118] The tooling plate 305 is fastened on the detection table by bayonet pins, which is convenient for removal or installation. The positioning die 3 is installed on the tooling plate 305, and the structure of the positioning die 3 is slightly changed due to the difference of the pump body. Compared with the embodiment 1, the positioning die 3 has increased the overall height.

Abstract

The invention relates to the technical field of detection equipment, in particular to a leak detection device for a pump body and leak detection equipment. The leak detection device for the pump body comprises a leak detection table top, a positioning die, a pressing mechanism, a sealing mechanism, and an inflation detection mechanism; the positioning die is used for mounting the pump body and sealing a first port in the lower side of the pump body; the pressing mechanism is used for abutting against the upper end face of the pump body; the sealing mechanism comprises a plurality of sealing assemblies which are used for sealing ports in all the side faces of the pump body correspondingly; and the inflation detection mechanism is used for abutting against one port of the sealed pump body, inflating a cavity in the pump body and detecting the air pressure of the cavity in the pump body; wherein the first sealing assembly facing one side of the second connected port in the pump body comprises a first driving part, an arm plate and an elastic sealing plate, the arm plate is installed at the output end of the first driving part, the elastic sealing plate is installed on the arm plate, and the first driving part drives the arm plate to move, so that the elastic sealing plate abuts against and seals the second connected port of the pump body. According to the leak detection device for the pump body and the leak detection equipment, the problems that an original leak detection method wastes time and labor, detection is inaccurate, and the percent of pass of factory pumps is seriously affected are solved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a leak detection device and leak detection equipment for a pump body. Background technique [0002] A pump is a machine that moves or pressurizes a fluid. Pumps can be divided into many types, such as water pumps, oil pumps and mud pumps, etc., but no matter what kind of pump, the pump body itself must be complete without cracks or other holes, so as to ensure the airtightness of the pump body. [0003] However, in the daily production process, due to the influence of factors such as production equipment or production technology, the pump body itself may have cracks or holes. In order to eliminate such pump bodies and ensure the pass rate of the pump body, it is necessary to prevent the pump body Leak detection. [0004] The existing leak-proof detection is to seal the sealing surface of the pump casing and the holes, then inflate, put the inflated pump casing into ...
