Problems solved by technology
[0002] In the process of transporting liquid media with high solubility such as pulp and bamboo pulp and domestic sewage, the center of the guide vane of the existing pump is generally set in the center of the flow channel of the pump body, and the guide vane is closed or semi-open. , fully open, in the process of transportation, the pump has high requirements on the conveying medium, and problems such as pump blockage and guide vane winding are prone to occur. The maintenance rate of the pump is high, which affects the work efficiency and also affects the quality of the product. impact, therefore, the existing technology is flawed and needs to be further improved and perfected

Embodiment Construction
[0024] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0025] The invention will be described in detail below with reference to the accompanying drawings and examples.
[0026] A permanent magnet drainage pump has a pump body 1 with a discharge port 10 and a water inlet 13; the pump body 1 is connected to a permanent magnet motor through a conversion shaft 2 and a motor main shaft 3;
[0027] The body has a casing 30, a top cover 31, a side wall 33, a spacer 35, and a base 36. The base 36 is provided with a main pump shaft 40, and the main pump shaft 40 is connected with a rear main gland 41. The gland 41 forms a sealed chamber 11 through the mechanical seal 42, the auxiliary seal 43 and the base 36. The mechanical seal 42 is accommodated on the casing 30, and the auxiliary seal 43 is accommodated on the base 36. The side of the casing 30 part is connected with...

The invention provides a permanent magnet type water draining pump. The permanent magnet type water draining pump comprises a pump body which is provided with a draining outlet and water inlets. The pump body is connected with a permanent magnet motor through a reverse shaft and a motor main shaft. The pump body is provided with a machine shell, a top cover sleeve, a side wall, a distance piece and a base. The base is provided with a main pump shaft. The main pump shaft is connected with a rear main press cover. A sealed cavity is formed by the rear main press cover and the base through mechanical sealing and auxiliary sealing. The periphery of the base is surrounded by at least two water inlets. Small impellers are arranged in the water inlets. Shafts of the small impellers rotate freely through ball bearings. The small impellers are driven by a driving motor to rotate. According to the water draining pump, the water inlet mode is optimized through the water inlets. Big impurities in liquid can be pre-filtered, so that the problems of blocking and winding due to the fact that the impurities entering the pump body are avoided.
Description
technical field [0001] The invention belongs to the technical field of pump structures, and in particular relates to a permanent magnet drainage pump. Background technique [0002] In the process of transporting liquid media with high solubility such as pulp and bamboo pulp and domestic sewage, the center of the guide vane of the existing pump is generally set in the center of the flow channel of the pump body, and the guide vane is closed or semi-open. , fully open, in the process of transportation, the pump has high requirements on the conveying medium, and problems such as pump blockage and guide vane winding are prone to occur. The maintenance rate of the pump is high, which affects the work efficiency and also affects the quality of the product. Influence, therefore, there are defects in the existing technology, need to further improve and perfect. Contents of the invention [0003] In view of this, the present invention aims to propose a permanent magnet drainage pu...
