Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump unit with a motor position adjustment structure. Background Art

[0002] A conventional water pump unit includes a water pump, a motor, and a base. The water pump and the motor are installed on the base. The pump coupling and the electric coupling are installed on the shaft extensions of the water pump and the motor respectively. The pump coupling and the electric coupling are connected to each other by pins and nuts. When the water pump coupling and the motor coupling are connected to each other, their concentricity is the most basic and important link in the installation of the equipment. If the concentricity of the water pump shaft and the motor shaft deviates too much, it will seriously affect the stability of the unit operation.

[0003] The fine-tuning of the concentricity of the water pump unit is generally carried out on the project site. The upper and lower heights of the motor are adjusted by gaskets during installation, and the front, rear, left and right positions are adjusted by a crane. However, the concentricity requirements between the water pump and the motor are relatively high, and it is difficult to fine-tune the concentricity purely by a crane. At present, the common adjustment method is to vertically weld adjustment blocks around the motor end of the base, connect screws to the adjustment blocks, and use the screws to extend and extend the support of the motor to adjust the concentricity of the unit. However, the vertically welded adjustment blocks protrude from the surface of the base. During maintenance, the motor cannot be withdrawn backwards from the tail of the base and then removed, so that when repairing the water pump, the motor can only be lifted away by a crane, which is very inconvenient.

[0021] In this embodiment, the fixed block 5 and the adjusting block 6 are made of cast steel and are precision cast. Eight fixed blocks 5 are evenly distributed around the motor mounting platform 3, with two fixed blocks 5 on each side. The fixed blocks 5 are fixed to the motor mounting platform 3 by welding, and the surface of the fixed blocks 5 is 2 to 3 mm lower than the surface of the motor mounting platform 3.
