Technical field
This utility model relates to technical field of hydraulic pressure, especially relates to a kind of prepressing type pneumatic pump.
Background technology
In hydraulic technique industry, pneumatic pump mainly uses air pressure to be that power produces pressure to fluid, enters one simultaneously
Step compression fluid makes it produce high pressure, and exports hydraulic oil for equipment use.Existing pneumatic pump is typically direct press type
Structure, it is in use, it is impossible to carry out supercharging in advance, directly gives big pressure, uses equipment in the process of use
In due to pressure increase too fast, it is easy to cause equipment occur leakage, damage equipment, due to pressure increase too fast, also make to set
Standby service life reduces, thus adds the maintenance cost of equipment.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and can carry out precompressed and ensure equipment safety and increase
Add the prepressing type pneumatic pump in service life.
This utility model solves its technical problem and be the technical scheme is that a kind of prepressing type pneumatic pump, including storage
Oil tank, is provided with cylinder on described oil storage tank, is provided with hydraulic oil outlet and air inlet, its feature on described oil storage tank
It is, is provided with oil-out bottom described oil storage tank and passes through the first pipeline and hydraulic oil outlet, in described oil storage tank
Portion is provided with high-voltage tube, and the axostylus axostyle of described cylinder inserts high-voltage tube and provides hydraulic oil, is provided with first single on described high-voltage tube
To valve and the second check valve, high-voltage tube is connected by the first described check valve with in oil storage tank, and the second described check valve is by height
Pressure pipe, by second pipe and hydraulic oil outlet, is provided with Unidirectional solenoid valve and the 3rd unidirectional on described second pipe
Valve, is provided with the bottom of pneumatic operated valve connection cylinder on described cylinder.
The most concrete, it is provided with unloading port bottom described oil storage tank.
The most concrete, described oil storage tank is provided with oil level pipe.
The beneficial effects of the utility model are: after have employed said structure, by by the way of using precompressed before supercharging,
Make pressure increase present gradient type, it is possible to well protection use equipment, do not have leakage and damage, improve use and set
In standby service life, reduce the maintenance cost of use equipment.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is explained in detail.
A kind of prepressing type pneumatic pump, including oil storage tank 1, is provided with cylinder 2 on described oil storage tank 1 as shown in Figure 1,
Described oil storage tank 1 is provided with hydraulic oil outlet 3 and air inlet 4, is provided with oil-out 5 by the bottom described oil storage tank 1
One pipeline 6 connects with hydraulic oil outlet 3, is provided with high-voltage tube 7 inside described oil storage tank 1, and the axostylus axostyle of described cylinder 2 inserts
High-voltage tube 7 provides hydraulic oil, is provided with the first check valve 8 and the second check valve 9 on described high-voltage tube 7, and described first is single
Being connected in oil storage tank 1 by high-voltage tube 7 to valve 8, high-voltage tube 7 is passed through second pipe 10 and high pressure by the second described check valve 9
Oil export 3 connects, and is provided with Unidirectional solenoid valve 11 and the 3rd check valve 12 on described second pipe 9, at described cylinder 2
It is provided with pneumatic operated valve 13 and connects the bottom of cylinder 2；Unloading port 14 it is provided with bottom described oil storage tank 1, convenient in oil storage tank 1
Hydraulic oil is replaced；Described oil storage tank 1 is provided with oil level pipe 15, conveniently the position of the hydraulic oil in observation oil storage tank 1, with
Just continue and add.
The operation principle of prepressing type pneumatic pump: first air inlet air inlet, the hydraulic oil in oil storage tank 1 is through oil-out
5, the first pipeline 6 and hydraulic oil outlet 3 supply use equipment, complete pre-pressing stage, uses equipment contact workpiece.Afterwards, gas
Dynamic valve 13 air inlet, when cylinder 2 makees drawback movement, sucks the hydraulic oil in oil storage tank 1 in high-voltage tube 7 from the first check valve 8
(now the second check valve 9 is closed)；The axle of exhaust hood 2 stretch out, the first check valve 8 is closed, and the hydraulic oil in high-voltage tube 7 is from
Two check valves 9 flow in the second oil pipe 10, then are not powered on through Unidirectional solenoid valve 11(, and hydraulic oil will not reflux in oil storage tank 1),
3rd check valve 12 is in hydraulic oil outlet 3 inflow use equipment, and produces high pressure.When needing release, pneumatic operated valve 13 closes holds one's breath
Source, Unidirectional solenoid valve 11 is energized, and the 3rd check valve 12 only does precompressed starting state, so when using equipment backhaul, hydraulic oil
Through the 3rd check valve 12, Unidirectional solenoid valve 11(is energized) it is back in oil storage tank 1, complete reseting stage.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any in form
Restriction, any simple modification, equivalent variations and the modification that above example is made by every technical spirit according to the present invention,
All still fall within the range of technical solution of the present invention.
