Swash plate is installed, adds end cap installation plunger the most again, cause the assembling trouble of entirety.Also some enterprises are had to incite somebody to action
Cylinder body is set to the tubbiness that upper end closed, lower end are uncovered, and offers plunger hole and oilhole at top, make swash plate from
Lower end is installed.But, owing to cylinder head is connected to the end face of cylinder body, oilhole is completely obscured, need during oiling
Cylinder head is dismantled, uses and inconvenient；Further, the hole at this cylinder body top is more, is unfavorable for cylinder body top
Structural strength.Moreover, existing cylinder head water inlet flow channel and outlet passage are the hole of diameter 6mm, and it is clear
Wash pressure unsatisfactory.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to use, height that structural strength is high
Pressure injection penetrates multipurpose water pump.
The technical solution of the utility model is as follows: a kind of high-pressure injection multipurpose water pump, including cylinder body with fixing
At the cylinder head of cylinder body upper end, in described cylinder body, swash plate is installed, described cylinder head is provided with water inlet flow channel,
Outlet passage is also provided with three vertical plungers, and these three plungers are uniform along the central shaft circumference of swash plate, and
And the lower end of described plunger stretch into cylinder body in match with swash plate, described cylinder body is that upper end closed, lower end are uncovered
Tubbiness, have at the top of described cylinder body three with plunger plunger hole one to one, under described plunger
End stretches in cylinder body along corresponding plunger hole, and the sidewall at described cylinder body has oilhole, pacifies on described oilhole
Equipped with plug.
Using said structure, the sidewall at described cylinder body offers oilhole, need not dismantle cylinder head, make during oiling
With convenient；Further, the perforate at cylinder body top reduces, the beneficially raising of cylinder body top structure intensity,
Be conducive to integrally-built reinforcement.
Described cylinder body top down convexes to form three uniform ribs of circumference, described rib and plunger hole
Interval is arranged, has the most uncovered screwed hole on each rib, and described cylinder head is by wearing from top to bottom
Cross cylinder head and insert being bolted on cylinder body in screwed hole.So it is threaded hole and makes fixing more of cylinder head
Add firmly, and, rib further increases the structural strength at cylinder body top, beneficially service life
Extend.
Just position to plunger hole week side, described cylinder body top is downwardly extending the reinforcement guide part of tubulose.Add
It is strongly guided portion on the one hand can the installation of plunger be guided；On the other hand improve the structure at cylinder body top
Intensity.
The lower end outward flanging of described cylinder body forms ring flange, has four groups of circumferences uniform on described ring flange
Via, each group of via is provided with two the most side by side.
It is connected between the lateral wall of described cylinder body and ring flange and has vertical reinforcement.Be conducive to improving flange
Bonding strength between dish and cylinder body, and the structural strength of cylinder body self is strengthened further.
The aperture of described water inlet flow channel and outlet passage is 8mm.By strengthening the runner in cylinder head, effectively carry
High cleaning hydraulic pressure.
Beneficial effect: this utility model, by offering oilhole at the sidewall of cylinder body, need not during oiling dismantle cylinder
Head, uses convenient；Further, the perforate minimizing at cylinder body top, beneficially cylinder body top structure intensity
Improve, thus provide a kind of easy to use, high-pressure injection multipurpose water pump that intensity is high, there is design skilful
The features such as wonderful, transformation is easily and improvement cost is low.
