Abstract
The utility model comprises a diesel engine pump seat, a pump chamber and an impeller, wherein, the pump chamber is combined with the pump seat to be directly combined with the diesel engine by using a combined disk of the pump seat to form an integral water pump. The pump seat is provided with a central hole; an output shaft of the diesel engine penetrates through the central hole to be communicated with the inside of the pump chamber; a sealing ring is arranged between the output shaft and the central hole; the impeller is arranged on the shaft of the diesel engine. The utility model has advantages of elimination of a chassis, a shaft coupling and bearings, reduced volume and weight, greatly reduced cost, convenient transportation and easy maintenance.
Description
The utility model belongs to the pump technology field.
Agricultural diesel pump all is split type at present, comprises chassis, diesel engine, the pump housing and coupling.The diesel engine and the pump housing are contained on the chassis, connect with coupling therebetween.This kind water pump volume is big, weight is big, and its chassis weight is about more than 1/4th of complete machine, has increased cost of production, and transportation and use are all required great effort very much.And, improper if coupling is installed, can produce bigger vibration and noise in the work.
The purpose of this utility model is to provide a kind of integral type diesel pump that does not have coupling, no chassis, no bearing.
The purpose of this utility model is achieved in that a kind of integral type diesel pump, comprises diesel engine, pump seat, pump chamber, seal ring and impeller.Pump chamber and pump seat combine, and directly combine with diesel engine with the conjoint disk of pump seat, constitute an integral type water pump.One center hole is arranged on the pump seat, and the output shaft of diesel engine passes this center hole and feeds in the pump chamber, between output shaft and the center hole seal ring is housed.Impeller directly is contained on the output shaft, rotates in pump chamber with output shaft the water supercharging is discharged.
The utility model has the advantages that, because being directly installed on, pump chamber and pump seat constitute integrated water pump on the diesel engine, save chassis, coupling and bearing, but can significantly reduce volume, weight reduction, for the weight reduction of constant power water pump more than 1/4, and because member reduces, structure is simpler, cost can reduce in a large number, convenient transportation, more easy-maintaining has distinct economic.
Fig. 1 is a structural drawing of the present utility model.Fig. 1 is described as follows: 1 is pump seat, and 2 is pump chamber, and 3 is impeller, and 4 is the pump seat center hole, and 5 is diesel engine, and 6 is the diesel engine output shaft, and 7 is seal ring.
An embodiment of the present utility model 1 is described below in conjunction with the accompanying drawings: pump chamber 2 combines with pump seat 1, directly combines with diesel engine with the conjoint disk of pump seat 1.Pump seat center hole 4 is arranged on the pump seat 1, and diesel engine output shaft 6 passes pump seat center hole 4 and feeds in the pump chamber 2.Between diesel engine output shaft 6 and the pump seat center hole 4 seal ring 7 is housed, impeller 3 directly is contained on the diesel engine output shaft 6 and rotates with output shaft.
