Abstract
The utility model relates to a vehicle loaded pump. The output pressure of a common vane pump is comparatively low, and the vane pump can not suitable for the tilting operating requirement of the spray irrigation vehicle. The vehicle loaded pump comprises a pump body 3 with a water inlet 1 and a water outlet 2. A working chamber 4 of the pump body 3 is provided with an impeller 5; the pump body 3 is provided with a pump cover 6 which is provided with a stop block 7 for controlling a work clearance of the impeller 5. The product is used as a vehicle loaded output water pump on the spray irrigation vehicle.
Description
The utility model relates to a kind of blade-type pump that uses on motor-driven sprinkling truck.
Common blade-type pump delivery pressure is lower, and can not adapt to the tilting job requirement of sprinkling truck.
The purpose of this utility model is to provide a kind of Vehicle loaded pump, and the delivery pressure height can tiltingly be installed.
The purpose of this utility model is achieved in that
Vehicle loaded pump, its composition comprises: have the pump housing of water inlet and water outlet, the impeller that in pump housing epitrochoidal chamber, is equipped with, the armored pump lid is equipped with the locating part of the working clearance of adjusting impeller on the pump housing on the pump cover.
Above-mentioned Vehicle loaded pump, the area of water inlet are greater than the area of water outlet, and its diameter is than being (1.8-2.2): 1.
Above-mentioned Vehicle loaded pump adopts mechanical seal between the described impeller wheel shaft and the described pump housing.
Advantage of the present utility model is:
1. by adjusting the relative position of the pump cover and the pump housing, can adjust blade and pump cover particularly blade and the gap of the pump housing in pump chamber, reach the purpose of the delivery pressure of adjusting pump thus.
Since the area of water inlet greater than the area of water outlet, capacity of water supply is good, the diameter ratio of the intake-outlet of common blade pump was less than 1.5: 1, can not adapt to the requirement of flow after delivery pressure is big, the diameter of intake-outlet is than being (1.8-2.2) in this product: 1, can satisfy need of work through check.
3. adopt mechanical seal structure between the impeller wheel shaft and the pump housing, strengthened the stability of axle mode of operation, strengthened the location of axle, therefore can tilting installation on sprinkling truck, after testing and test, can satisfy job requirement fully.
Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is left views of accompanying drawing 1.
Be further described below in conjunction with accompanying drawing:
Embodiment 1:
Vehicle loaded pump, its composition comprises: have the pump housing 3 of water inlet 1 and water outlet 2, the impeller 5 that in the pump housing 3 epitrochoidal chambers 4, is equipped with, armored pump lid 6 is equipped with the locating part 7 of the working clearance of adjusting impeller 5 on the pump housing 3 on the pump cover 6.
Embodiment 2:
Vehicle loaded pump, the area of described water inlet 1 are greater than the area of water outlet 2, and water inlet is (1.8-2.2) with the diameter ratio of water outlet: 1.The rear end of wheel shaft 8 has the positioning supports bearing.
Embodiment 3:
Above-mentioned Vehicle loaded pump adopts mechanical seal 9 to seal between the wheel shaft 8 of impeller 5 and the pump housing 3.
Claims (3)
1. Vehicle loaded pump, its composition comprises: the pump housing that has water inlet and water outlet, the impeller that is equipped with in described pump housing epitrochoidal chamber is characterized in that: armored pump lid on the described pump housing, be equipped with the locating part of the working clearance of adjusting described impeller on the described pump cover.
2. Vehicle loaded pump according to claim 1 is characterized in that: the area of described water inlet is greater than the area of water outlet, and its diameter is than being (1.8-2.2): 1.
3. Vehicle loaded pump according to claim 1 and 2 is characterized in that: adopt mechanical seal between the described impeller wheel shaft and the described pump housing.
