Problems solved by technology

[0003] After the canned pump is produced, it is necessary to test the airtightness of the pump body. The structure of the device for testing the airtightness of the canned pump in the prior art is relatively simple, and the connection with the pump body is relatively low, which makes the detection data error larger , especially in the environment where the temperature difference changes greatly, because the change of temperature will easily cause the change of gas volume, which is not conducive to the reasonable detection of the air tightness of the pump body

Abstract

The invention discloses an air tightness testing device for a shielded centrifugal pump, which comprises an inner tank, a casing and a pump body. The interior of the housing is divided into a detection slot and an installation slot. There is an opening at the position corresponding to the detection slot on the top of the housing, and a sealing cover is provided on the top of the opening. One side of the sealing cover is movably connected with the housing through a hinge, and the other side of the sealing cover is The lifting device is fixed inside the detection tank, the pump body is placed on the output end of the lifting device, one end of the pump body is provided with an air inlet, and the outer side of the inner tank is provided with a temperature control device. The control device includes an installation shell, a heating pipe, a blower device, a temperature sensor and a control panel. The installation shell is located on the outside of the inner tank. This shielded centrifugal pump air tightness test device can perform constant temperature testing on the air tightness of the pump body, and The sealing performance of the connection between the pump body and the detection device is better, and the error of the air tightness detection of the pump body is reduced.

Description

Technical field[0001]The present invention relates to a mask centrifugal pump airtight test technology, and is specifically a shielded centrifugal pump airtight test device.Background technique[0002]The driving of the ordinary centrifugal pump is to connect the impeller shaft of the pump to the electric axis through the coupling to rotate the impeller and the motor, and the shielding pump is a non-distained pump, the pump and the drive motor are sealed in one In the pumping medium full of pressure vessels, this pressure vessel only seals, and is provided by a wire group to provide a rotating magnetic field and drive the rotor. This structure cancels the rotating shaft sealing device having a conventional centrifugal pump, so it can do completely without leakage.[0003]After the production is completed, the mask is required to detect the airtightness of the pump body. The prior art is simple in the device structure of the mask pump, and the connection is low, which makes the detection...
