Problems solved by technology

The existing practice is to test air tightness on special air tightness testing equipment. For small batch production, the cost of introducing air tightness testing equipment is high, which is not conducive to controlling production costs. In addition, through air tightness The efficiency of testing equipment to detect the airtightness of the pump cover is low, which is not conducive to improving production efficiency. Therefore, it is necessary to design a simple and efficient airtightness detection device to solve the above problems

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0015] a kind of like Figure 1-2 The pump cover air tightness testing device shown is used for pump cover air tightness testing. It mainly includes a pump cover sealing structure, and the pump cover sealing structure includes a bottom plate 1 . A sealing base 2 is arranged on the bottom plate 1, and the top surface of the sealing base 2 is a plane. Two positioning pins for positioning the pump cover are also arranged on the top surface of the sealing base 2 . The connecting end surface of the lower part of the pump cover is close to the top surface of the sealing base 2, and usually seals are used on the contact surface between the pump cover and the sealing base 2. In this embodiment, the connecting end surface of the pump cover itself has an annular sealing groove, and A sealing ring is provided in the sealing groove; in other embod...

Abstract

The invention discloses a pump cover air tightness detection device which is characterized by comprising a pump cover sealing structure; wherein the pump cover sealing structure comprises a bottom plate, a sealing base is arranged on the bottom plate, a connecting end face of the lower portion of a pump cover is tightly attached to the top face of the sealing base, and a sealing ring is arranged on the connecting end face of the pump cover; a pressing mechanism is arranged on the bottom plate; a plugging head is arranged at a pump outlet of the pump cover, and a supporting column is further arranged in the direction right opposite to the plugging head. A gas receiving end cover is arranged at a port of the top face of the pump cover, an annular sealing ring is arranged between the gas receiving end cover and the contact face of the pump cover, a bolt is arranged on the gas receiving end cover and matched with a threaded hole in the sealing base so that the gas receiving end cover can be tensioned, and a gas nozzle used for being connected with a gas pipe is further arranged on the gas receiving end cover. The air leakage detection device has the advantages of being simple in structure, low in manufacturing cost, good in sealing effect, high in detection efficiency and suitable for air leakage detection of small-scale machining.

Description

technical field [0001] The invention relates to the field of pump cover leak detection structure, in particular to a pump cover air tightness detection device. Background technique [0002] The water pump pump cover is an important part of the water pump, so the water pump is required to withstand pressure and not leak. Therefore, after the pump cover is machined, it is necessary to test the air tightness. The air tightness test is mainly to detect whether there are trachoma on the pump cover, so as to reflect whether the water leaks during the later use of the pump. The existing practice is to test air tightness on special air tightness testing equipment. For small batch production, the cost of introducing air tightness testing equipment is high, which is not conducive to controlling production costs. In addition, through air tightness The efficiency of testing equipment to detect the airtightness of the pump cover is low, which is not conducive to improving production eff...
