Model utility content
In view of this, technical problem to be solved in the utility model is: provide a kind of low-specific-speed high-efficiency centrifugal pump that significantly can promote working efficiency.
In order to achieve the above object, the utility model adopts following technological scheme to realize:
A kind of low-specific-speed high-efficiency centrifugal pump, comprise and there is spiral case, water inlet coupling plate, the centrifugal pump body of impeller and pump shaft, described water inlet coupling plate has water intake and export mouth, described spiral case has introducing port and water outlet, the export mouth of described water inlet coupling plate is connected with the introducing port of described spiral case, described impeller is positioned at described spiral case and is provided with blade in the wheel face in the face of described water inlet coupling plate, described spiral case has axis hole in correspondence described impeller core wheel position, described pump shaft is set in described axis hole and with the core wheel transmission of described impeller and is connected, wherein, the diameter D1 of described impeller is 200-220mm, Inlet cone angle α is 15-27 °, exit angle β is 30-38 °, the thickness δ 1 that described blade is positioned at described impeller eye end is 4-6mm, the thickness δ 2 being positioned at described impeller outlet end is 8-12mm, described blade comprises linear leaf and is located at the short blade between adjacent described linear leaf between two parties, the position diameter D2 of described short blade is 0.4-0.6 times of described impeller diameter D1.
As preferably, the core wheel place of described impeller wears and hangs with bolt, and described bolt spiral shell is solidly connected on described pump shaft, and between the core wheel of described impeller and described pump shaft, cover is connected with connecting key, and described impeller and pump shaft drive key to connect by described connecting key.
As preferably, between the export mouth of described water inlet coupling plate and the introducing port of described spiral case, chuck has seal ring.
As preferably, the water intake of described water inlet coupling plate is provided with water filling plug.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is by adopting spatial warping deviated splitter vane and making it can significantly improve working efficiency, highly effective to the setting of the specifications parameter that it relates to.In view of the hydraulic loss of water pump is mainly because water inevitably there will be whirlpool in flow process, this patent have employed the design method of deviated splitter vane, and optimizes the molded line of blade, controls the whirlpool loss in impeller channel, reduce the hydraulic loss of water pump, working efficiency improves 10% ~ 15%.Its working principle is as follows: start before by the water filling plug on water inlet coupling plate to water filling in water pump, then the outer power-driven pump axle running of transmission, pump shaft is connected with impeller by connecting key, thus drives impeller rotates, water enters impeller by water inlet coupling plate water intake, and impeller is by rotation forces water flow, and swiftly flowing water enters in volute by impeller outlet, be the potential energy of water by the kinetic transformation of water in volute, finally flow out from water outlet.
