Description
Technical field
The present invention relates to the technical field of cleaning machine high-pressure pump, more particularly, to a kind of high-pressure swash-plate pump of washing machine.
Background technology
Jetting machine, it is high-pressure plunger pump is produced water under high pressure to rinse the machine of body surface by power set,
It can peel off dirt, wash away, and reach the purpose on cleaning of objects surface.Cleaning machine high-pressure swash-plate pump traditional at present, including
Pump case, pump cover and pump head, pump case is interior to be provided with by driving shaft-driven swash plate, and swash plate is provided with plane bearing, and pump case passes through pump
Lid is fixedly connected with pump head, is provided with three plunger holes in pump head, is respectively equipped with through pump cover and is extended in pump case in three plunger holes
To the plunger on plane bearing, the side on three plungers respectively close to its end in pump case is provided with spring base, spring on top
Back-moving spring is respectively equipped with three plungers between seat and pump cover, pump head is provided with inlet pipeline, circulating water line and water outlet
Pipeline, inlet pipeline are provided with water inlet and delivery port, and delivery port is provided with temperature-sensing valve, divided in inlet pipeline and circulating water line
The limbers that She You do not connected with three plunger holes, circulating water line is interior to be provided with the intercommunicating pore connected with outlet pipeline, outlet pipe
Road is provided with high pressure faucet, and the water side of circulating water line connects with the inlet pipeline close to water inlet.When High Pressure Gun is in
Overflow valve is opened when closing rifle, in pump forms low pressure water circulation in pump, and water constantly rubs in circulatory flow with runner to be made in pump
Produce the temperature-sensing valve that high temperature is arranged on when water temperature reaches 48-60 degrees Celsius in pump on inlet pipeline and open discharge hot water, rely on
Tap water pressure injects need not go to close power set when cold water closes rifle so as to realize.
This high-pressure swash-plate pump in above-mentioned in the environment of pump water, then can not normally be made simple using plunger pump
With such as when either bucket or water tank do not possess the water source of hydraulic pressure to the water in using pond, the product enters from inlet pipeline
In the mouth of a river intake, then water is pumped into circulating water line from plunger hole by the plunger of plunger pump, then from outlet pipeline it is defeated
Go out, when High Pressure Gun, which is in, closes rifle, overflow valve is opened and low pressure water circulation is formed in pump in pump, water in circulatory flow with runner
Constantly friction makes to produce in pump high temperature when water temperature reaches 48-60 degrees Celsius in pump, be arranged on temperature-sensing valve on inlet pipeline because
For when self-priming works on inlet pipeline without hydraulic pressure thus temperature-sensing valve open after can not discharge hot water, ultimately result in temperature-sensing valve and be in
Open mode, vacuum, which reduces, in pump can not use self-suction function, and term is run can cause pump inner seal liner and other zero
Part damages.
