Description

Technical Field

[0001] The utility model belongs to the technical field of pump body installation, in particular to a welding base for a double-suction pump. Background Art

[0002] The double-suction pump is a centrifugal pump introduced from abroad. It has been developed and evolved in China for decades. Due to its characteristics of high head and large flow, it is more common in large-scale water supply, drainage and irrigation projects. As we all know, the double-suction pump is mainly composed of two parts: the pump head and the motor, which are connected by a coupling in the middle. The pump head and the motor are fixed on the same base, installed in the factory, and then transported to the site for assembly as a whole, which is convenient and fast.

[0003] The welding base currently on the market usually uses a whole thick steel plate as a support at the motor mounting end, and then fixes two motor fixing plates on the thick steel plate. Four round holes are opened on the motor fixing plate to fix the motor. However, such a structure has some problems. Since the support uses a whole thick steel plate, the entire welding base is too bulky and inconvenient to lift and move. The motor is fixed by four round holes on the motor fixing plate, which has poor versatility and cannot be applied to motors with different fixed spacings in the same motor frame number. In addition, the position accuracy of the motor is required to be high, and the actual assembly process is time-consuming and labor-intensive. Utility Model Content

[0004] The main purpose of the utility model is to propose a welding base for a double-suction pump, which can effectively solve the problems in the background technology.
