Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
Being used in the present embodiment driving inventive drive means is motor, can use electricity in other any embodiments
Machine, it would however also be possible to employ can mate and can meet any driving means driving requirement with the present invention, such as: motor, diesel oil
Machine, gasoline engine etc., owing to driving means is the most thinkable prior aries of those of ordinary skill in the art, be not detailed at this.
Shown in accompanying drawing 1-2, a kind of piston type high pressure water pump, including housing 1, cylinder body 2 and actuating device, described transmission
Device two ends connect the first piston 3 and the second piston 13 being arranged in described cylinder body 2 respectively, connect in the middle part of described actuating device
There are power shaft 9, described cylinder body 2 to be provided with water inlet 19 and outlet 16, described water inlet 19 be provided with water feeding one-way valve 18,
Being provided with out water one-way valve 12 in outlet 16, described water inlet 19 and outlet 16 are positioned on the same circumference on cylinder body 2.
Operation principle:
Driving power shaft 9 by motor, power shaft 9 drives actuating device, described actuator drives to be connected to described transmission dress
First piston 3 and the second piston 13 of putting two ends do linear reciprocating motion the most in opposite directions in cylinder body 2 simultaneously, thus due to close
Close the linear reciprocating motion in opposite directions in space and can cause increase and the change of reduction of pressure generating period in cylinder body 2, when
During described first piston 3 and the second piston 13 move toward one another, when along with between described first piston 3 and the second piston 13
Distance is increasingly nearer, and the spatial dimension in cylinder body 2 is squeezed and tapers into, and does not have compressibility, therefore cylinder due to water
Pressure in body 2 will steeply rise, thus get rid of by going out water one-way valve 12, form high-pressure fluid；In like manner, when along with described
Distance between one piston 3 and the second piston 13 is more and more remote, and the spatial dimension in cylinder body 2 becomes larger because of expansion, cylinder body 2
Interior pressure will drastically decline, thus be sucked by water feeding one-way valve 18, and form the motion being iteratively repeated as procedure described above
In the cycle, along with the continuous increase of motor speed, the discontinuity of output water constantly weakens, after motor reaches specified stabilized (steady-state) speed,
Output hydraulic pressure region is steady, meets normal high voltage demands.
