Abstract
The utility model relates to a novel vertical self suction pump. The periphery of an impeller is provided with a blade type pressure magnifying device. An air and water separating device which is composed of an isolating sleeve and an isolating plate is arranged above the pressure magnifying device. One side of a water inlet is provided with a vacuum damage valve. The closing and opening of the valve is synchronous with the start and the stop of a motor. The utility model has the advantages of simplified structure, small volume, light weight, short self suction time, large self suction height, high reliability, and small hydraulic loss. The utility model is suitable for pumping and conveying clear liquid and sewage with larger granules. The utility model has a substantial improvement compared with existing self suction pumps which adopt a vortex casing type water pressing chamber and a water return preventing and stopping valve.
Description
The utility model relates to a kind of novel vertical self-priming pump, belongs to pump series products technical field.
Self-priming pump is fit to pump the sewage and the clean liquid of band particle, and need not to pour water to pump chamber during starting, can across-the-line starting, thereby be used widely.Existing self-priming pump adopts the voluted type pumping chamber, and this voluted type pumping chamber is used for vertical pump, and complex structure increases the volume and weight of pump.Still contain liquid for guaranteeing to shut down in the pump chamber of back, existing self-priming pump is equipped with the check valve of various types in inlet.Resistance is big first to adopt check valve, and hydraulic loss is also big, influences self-priming time and self-priming height, and is difficult to by bigger particle; Second poor reliability, when being not closed completely, liquid just because siphonage flows in the priming reservoir gradually, when pump is started once more, still need be poured water in the pump.Simultaneously, when existing self-priming pump started, the air-water separation weak effect had prolonged self-priming time, generally needs 100～120 seconds, could proper functioning.
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of designs simplification, volume little, in light weight, and self-priming time is short, the reliability height, and hydraulic loss is little, can pump the novel vertical self-priming pump that contains larger particles liquid.
The technical solution of the utility model is: the novel vertical self-priming pump is mainly by the pump housing, pump bracket, motor, impeller, Diffuser, axle envelope with prevent to shut down that liquid reflux device constitutes in the pump of back.Improvements are: described Diffuser is the blade diffuser that is arranged on the impeller periphery, and this Diffuser top is provided with the moisture trap of being made up of dividing plate, spacer; Above-mentioned anti-liquid reflux device is a vacuum breaker valve, the closing of this valve, opens and the opening, stop synchronously of motor.
As further improvement of the utility model, the solenoid valve that described vacuum breaker valve adopts guide line to link to each other with connection box for motor.
Adopt blade diffuser structure greatly to be simplified, thereby reduced the volume and weight of pump than employing voluted type pumping chamber.Because the Diffuser top is provided with the moisture trap of being made up of dividing plate, spacer, during starting, gas-liquid mixture enters pump chamber through Diffuser, bump spacer outer leafs, speed slows down, air is separated rapidly, and water falls in the dividing plate, returns impeller from backwater hole, so circulation, very fast air in the pump suction pipe is drained, the pump proper functioning, self-priming time shortens half than existing self-priming pump.When pump was shut down, vacuum breaker valve was opened simultaneously, and pump inlet/outlet place all communicates with atmosphere, and full water is still stored up in pressure balance in the pump chamber, when guaranteeing to start shooting once more, and starting smoothly.Adopt solenoid valve, the reliability height reduces hydraulic loss, and does not influence passing through of larger particles.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Motor 1 is fixed on the pump bracket 2, and the pump housing 9 links with pump bracket, and its both sides are provided with water intake 12, water outlet 6.Impeller 10 links to each other with motor by pump shaft 3, and the binding site of pump shaft and pump bracket is provided with axle envelope 11.Impeller outer is arranged with blade diffuser 7, and the Diffuser top is provided with spacer 5, dividing plate 4, and backwater hole 8 is arranged on the dividing plate.The water intake top is provided with solenoid valve 13, and the guide line of this solenoid valve links to each other with the terminal box of motor.
