Abstract
Disclosed is a punched stainless steel multistage pump which relates to the pump products. An inlet-outlet base is arranged at one side of a pump body and a liquid inlet and a liquid outlet are arranged on the inlet-outlet base; a pump body support is arranged at the other side of the pump body; the pump body is fixed by the pump body support and the inlet-outlet base; a main shaft arrange at the center of the pump body is connected with a motor; multistage of impellers are evenly distributed on the main shaft; the discharge ends of the impellers are respectively provided with a guide vane and a guide vane cover is arranged on the outside diameter of the guide vane; three-dimensional helical guide blades are evenly distributed from the suction ends of guide vane bodies of the guide vanes to the discharge ends along the outside diameter; therefore the liquid flows reasonably with little resistance, little impact force and quick flow speed under the action of the three-dimensional helical guide blades when being changed to flow in the axial direction instead of the radial direction through the guide vanes; and with low power consumption, high efficiency, little vibration force and low noise, the utility model is applicable to various punched stainless steel multistage pumps.
Description
Technical field the utility model relates to the pump class, says it is a kind of punching press stainless steel multistage pump in detail.
We know background technique, existing punching press stainless steel multistage pump, be to be provided with the import and export pedestal in the pump housing one side, import and export pedestal and be provided with liquid entering hole and liquid outlet, pump housing opposite side is provided with pump housing bearing, pump housing bearing and import and export pedestal be the pump housing fixedly, pump housing center is provided with main shaft, and main shaft connects motor, even cloth multi-stage impeller on the main shaft, the end that spues of each grade impeller is respectively equipped with stator, the stator external diameter is provided with the stator cover, and stator is at the guide vane of the even cloth arc of end that spues, during work, the motor drives main shaft, impeller is rotated, and liquid enters through liquid entering hole, and suction side and external diameter through stators at different levels under the drive of impellers at different levels enter the end that spues, discharge opening through stator covers at different levels spues, and enters liquid outlet and discharge between the stator cover and the pump housing.This punching press stainless steel multistage pump, because stator is just spared the guide vane of cloth arc at the end that spues of diffuser, the suction side of diffuser and the outside are smooth planes, the movement-oriented device of no tangent line on the suction side of stator and the external diameter, liquid is when radially transferring axial flow to, resistance is big, and impact force is big, and flow velocity is slow, cause the power consumption height, efficient is low, and vibration force is big, and noise is big.
The technical problem that summary of the invention the utility model solves is, the suction side and the outside that solve stator are smooth planes, the movement-oriented device of no tangent line on the suction side of stator and the external diameter, liquid are when radially transferring axial flow to, and resistance is big, impact force is big, flow velocity is slow, causes the power consumption height, and efficient is low, vibration force is big, the problem that noise is big.
The technical solution of the utility model is, the pump housing one side is provided with the import and export pedestal, import and export pedestal and be provided with liquid entering hole and liquid outlet, pump housing opposite side is provided with pump housing bearing, pump housing bearing and import and export pedestal be the pump housing fixedly, pump housing center is provided with main shaft, main shaft connects motor, even cloth multi-stage impeller on the main shaft, the end that spues of each grade impeller is respectively equipped with stator, and the stator external diameter is provided with the stator cover, and its main structure characteristics are, stator be suction side at diffuser through external diameter to the end that spues, the helical guide vane of even cloth space multistory.
The beneficial effects of the utility model are and since stator be suction side at diffuser through external diameter to the end that spues, spare the helical guide vane of cloth space multistory, flow of liquid through stator when radially transferring axial flow to, under the effect of the helical guide vane of space multistory, form Rational flow, resistance is little, impact force is little, flow velocity is fast, and is low in energy consumption, the efficient height, vibration force is little, and noise is little.The utility model is applicable to various punching press stainless steel multistage pumps.
