Embodiment Construction
[0009] Such as figure 1 As shown in the figure, a kind of air tightness detection equipment of motor end cover, including end cover body 1, water tank 3, multi-stage centrifugal fan 2, U-shaped tube pressure gauge 4, U-shaped tube pressure gauge 4 and end cover are placed inside the water tank 3 The main body 1 and the multi-stage centrifugal sub-machine 2 are used to generate wind pressure and deliver it to the inside of the end cover main body 1 . The wind pressure generated by the multi-stage centrifugal fan 2 is delivered to the end cover body 1, and the air leakage of the end cover body 1 in the water of the water tank 3 is observed through the U-shaped tube pressure gauge 4 to judge whether the airtightness of the workpiece is qualified.
[0010] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention, and cannot be considered as limiting the implementation scope of the p...

The invention relates to the field of motor detection equipment, in particular to an airtightness detection unit for motor end covers. The airtightness detection unit comprises an end cover body, a water trough, a multistage centrifugal fan and a U-pipe pressure meter. The U-pipe pressure meter and the end cover body are disposed within the water trough. The multistage centrifugal fan is used for generating air pressure and delivering air into the end cover body. The airtightness detection unit has the advantages that the end cover is subjected to airtightness testing by the use of the special multistage centrifugal fan specially designed and the special test tool, the airtightness detection unit is simple in structure and convenient to operate, detection data are accurate, manufacturing cost is low, and cost is saved.
Description
technical field [0001] The invention relates to the field of motor testing equipment, in particular to an airtight testing equipment for a motor end cover. Background technique [0002] The motor end cover has requirements for air tightness, and the air tightness needs to be tested after the installation is completed. The existing testing equipment has complex structure, difficult operation, poor air tightness detection effect, and detection limitations. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of air tightness testing equipment for the motor end cover [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a kind of airtightness detection equipment of the motor end cover, including the end cover body, including a water tank, a multi-stage centrifugal fan, and a U-shaped tube pressure gauge, a...
