Description

Technical Field

[0001] The utility model relates to the field of fluid transportation, in particular to a vortex pump used for fluid transportation. Background Art

[0002] Currently, water plants have relatively little experience with sludge conveying, with most using cam pumps. Cam pumps are suitable for conveying sludge at relatively low concentrations, but become more difficult to convey as concentrations rise. Vortex pumps are now being used in various sludge conveying applications, improving the performance and reliability of fluid conveying systems. Vortex pumps offer advantages such as smooth operation, low noise, and high efficiency, effectively improving the efficiency and quality of fluid conveying.

[0003] The common problems of vortex pumps at this stage are: 1. The pump head of the vortex pump has a strong integrity, and it is not easy to disassemble when the impeller is damaged or the flow channel is blocked; 2. The screws used to lock the pump head are prone to loosening; 3. When the vortex pump runs for a long time, the heat dissipation of the pump shaft and the rear end of the pump head is poor. Based on the above-mentioned defects, the utility model proposes a vortex pump for fluid transportation. The pump head part of the vortex pump adopts a combined structure, which is convenient for disassembly and assembly. At the same time, the anti-slip bolts can connect the front cover of the pump head, the pump head body and the bracket as a whole. The anti-slip bolts can prevent the vortex pump from loosening during operation, and the bracket, the pump head body and the front cover of the pump head are enclosed to form a three-sided ventilated pump casing structure. The pump casing structure has strong ventilation and can improve the heat dissipation of the pump shaft and the rear end of the pump head. Utility Model Content
