Description

Pump case frock

Technical Field

Background

As shown in fig. 1 and 2, the pump casing of the existing magnetic suspension centrifugal pump is mostly a volute type pump casing, which includes a lower casing 104 having a liquid outlet pipe bottom 103 and a top cover 105 having a liquid outlet pipe top 102, and a liquid inlet pipe 101 is vertically disposed at the top center of the top cover 105. The bottom 103 of the liquid outlet pipe and the lower shell 104 are integrally formed; effluent pipe top 102, liquid inlet pipe 101, and top cover 105 are integrally formed. When the top cover 105 covers the lower shell 104, a rotor accommodating cavity is formed between the top cover 105 and the lower shell 104, a liquid outlet channel is formed between the liquid outlet pipe bottom 103 and the liquid outlet pipe top 102, and the liquid outlet channel is arranged around the rotor accommodating cavity.

The magnetic suspension centrifugal pump is usually made of plastic, and in the design experiment stage, the top cover 105 and the lower shell 104 are connected in a bonding mode for saving cost.

If the top cover 105 and the lower shell 104 are connected in a bonding mode, after the top cover 105 and the lower shell 104 are glued, a certain time is needed to press the top cover 105 and the lower shell 104, so that the top cover 105 and the lower shell 104 are kept in a tightly-fitted state, the adhesive is solidified, and the problem that the top cover 105 and the lower shell 104 are not firmly bonded is avoided.

The existing volute type pump shell has the defects that the shape of the whole pump shell is irregular due to the radian of the top cover 105 and the spiral liquid outlet pipe. Therefore, there is no special tool to press the top cover 105 and the lower housing 104.
