Inserted sheet passes rear end cap, and the pump housing, which has, is provided with impeller in water inlet pipe and water inlet pipe, pump chamber, impeller is connected to the output shaft of motor
On.Because the water that the nozzle of current windshield sprays scatters shape, thus it is very high, it is necessary to pump to the performance requirement of pump
Operating pressure it is big, and operating current is small.
The content of the invention
The purpose of this utility model is, work good there is provided a kind of performance for the above-mentioned problems in the prior art
The big automobile cleaning pump of hydraulic pressure.
The purpose of this utility model can be realized by following technical proposal：A kind of automobile cleaning pump, including water inlet pipe, go out
Motor is installed in water pipe, pump cover, pump case and the end cap for being fixed on pump case upper end, described pump case, the motor it is defeated
Impeller is fixed with shaft, it is characterised in that described pump cover is removably fixed under the bottom of pump case, the pump case
End is structure as a whole with pump case, and pump chamber is formed between the bottom of the pump case and pump cover, and described impeller is located in pump chamber,
The outer surface of the bottom of the pump case is spill cambered surface, and the back side of the impeller is the spill cambered surface phase with pump case bottom
The arc surfaced matched somebody with somebody, described water inlet pipe is arranged at the sidepiece of pump case, and with being connected inside pump chamber, described outlet pipe is arranged at
On the side wall of pump cover, and it is connected with the inside of pump chamber.
Have in a kind of above-mentioned automobile cleaning pump, inside described pump case can limiting motor position spacing walls, institute
Seal is provided between the spacing walls and the output shaft of motor stated.This structure not only can limiting motor position, and also rise
To sealing function.
In a kind of above-mentioned automobile cleaning pump, pressure releasing chamber is left between described spacing walls and pump case.Pressure releasing chamber is set
Put the inside that can balance the automobile cleaning pump and outside pressure balance.
Compared with prior art, the pump case of this automobile cleaning pump employs split-type structural with pump cover, and outlet pipe is arranged on
On the side wall of pump cover, current can spray from the outlet pipe of the pump cover nearest from impeller, reduce the energy consumption of pump, while under pump case
End can produce vortex when rotating, add hydraulic pressure so that its service behaviour is more with impeller formation spill globoidal structure, impeller
It is good.
