Description
Technical field
The utility model is related to a kind of air pressure feed flow fuel tank of auxiliary hydraulic pump self-priming, especially a kind of hydrostatic forging machine liquid
The auxiliary self-priming fuel tank of press pump, fuel tank more particularly to a kind of closed and with certain pressure belongs to Gas fluid pressure transmission technology neck
Domain.
Background technology
The hydraulic power system of hydraulic press, not only needs to meet at a relatively high operating pressure, in addition it is also necessary to meet big flow
Working condition requirement.Usual people's selection work pressure is high and remains to keep the axial plunger pump of volumetric efficiency high under high pressure as liquid
The hydraulic pump of press, but because the self-priming performance of axial plunger pump is bad, and liquid has certain viscosity resistance, to oil suction stream
Amount has a certain impact, it is therefore necessary to increases auxiliary inlet port fuel feeding of the solution feed pump to hydraulic pump, could meet the suction of hydraulic pump
Oil is required.By taking 63MN hydrostatic forging machines as an example, it is commonly equipped with two auxiliary solution feed pumps of 110kw and is supplied to the inlet port of hydraulic pump
Oil, and the fuel system of auxiliary solution feed pump is uninterrupted fuel system.Supplied to hydraulic pump inlet port above by auxiliary solution feed pump
There is following drawback in the mode of oil：1st, need to be equipped with auxiliary solution feed pump, equipment investment is big, electric power installed capacity increases；2nd, between not
Disconnected work, power consumption is big, fault rate increase, poor reliability, operating cost are high；3rd, floor space is big.Accordingly it is desirable to have
A kind of innovative auxiliary feed liquid way, in applying to the fueller of hydraulic press hydraulic pump.
The content of the invention
The purpose of this utility model is the air pressure feed flow fuel tank for providing a kind of auxiliary hydraulic pump self-priming, realizes big flow
Hydraulic pump does not have the air pressure auxiliary self-priming of exterior power.
The utility model is implemented by the following technical programs：A kind of air pressure feed flow fuel tank of auxiliary hydraulic pump self-priming, including
Hydraulic pump, fuel tank, described hydraulic pump provide pressure oil to the hydraulic cylinder of hydraulic press；Described fuel tank provides hydraulic pressure to hydraulic pump
Oil；Oil return in the hydraulic cylinder flows into fuel tank, it is characterised in that：
Described fuel tank is closed container；
The fuel tank inner chamber top is set to air chamber, and bottom is set to liquid room；
Compressed air suits in the air chamber；
The inlet port of the hydraulic pump is arranged in the liquid room of the fuel tank inner chamber.
The compression pressure is more than 0.1Mpa.
Preferably, the compressed gas are nitrogen.
Preferably, the compressed gas are air.
The oil return opening is arranged in the liquid room of the fuel tank inner chamber.
The utility model uses air pressure fuel tank as the feed flow fuel tank of hydraulic press hydraulic pump, and filled with pressure in feed flow fuel tank
Strength body, making the oil of feed flow fuel tank has pressure and increases flow, so as to meet the big flow oil suction requirement of hydraulic pump, plays auxiliary
Help the effect of hydraulic pump self-priming.Fuel tank, hydraulic pump, the oily circulation loop of hydraulic cylinder closure are formd simultaneously, are not only reduced auxiliary
Equipment investment is helped, electric energy has been saved, has been reduced operating cost, also achieve hydraulic recovery utilization.
Brief description of the drawings
Accompanying drawing 1 is operation principle of the present utility model and structure diagram.
In fig. 1：1 is fuel tank, 2 is hydraulic pump, 3 is solenoid directional control valve, 4 is main hydraulic cylinder, 5 is backhaul hydraulic cylinder.
Specific embodiment
Explanation is further explained to the utility model below in conjunction with accompanying drawing：
As shown in Figure 1, the suction hydraulic oil from fuel tank 1 of hydraulic pump 2, to the main hydraulic cylinder 4 of hydrostatic forging machine and backhaul
Hydraulic cylinder 5 provides hydraulic oil；Oil return in main hydraulic cylinder 4 and backhaul hydraulic cylinder 5 flows into fuel tank 1, and fuel tank 1 is closed container, its
Top is set to air chamber, and bottom is set to liquid room；Compressed air suits in air chamber；The inlet port of hydraulic pump 2 is arranged in fuel tank 1
In the liquid room in chamber；Compression pressure is more than 0.1Mpa；Compressed gas are air or nitrogen；Main hydraulic cylinder 4 and backhaul hydraulic cylinder 5
Oil return opening be arranged in the liquid room of the inner chamber of fuel tank 1.
During utility model works, liquid room is formed to the hydraulic oil that about 2/3 cavity volume is injected in fuel tank 1 first, so
The air or nitrogen more than 0.1Mpa are filled with backward fuel tank 1, the air chamber on hydraulic pressure pasta top is formed；Start hydraulic pump 2, electromagnetism
The left of reversal valve 3 or right wing are powered, and the inlet port of hydraulic pump 2 obtains the air pressure feed flow of auxiliary oil suction from fuel tank 1, so as to master
Hydraulic cylinder 4 or backhaul hydraulic cylinder 5 provide the hydraulic oil of big flow, and fast drop is realized to meet main hydraulic cylinder 4, and backhaul hydraulic cylinder 5 is real
The need of work of existing quick return.
Also be recycled to the high pressure oil return in main hydraulic cylinder 4 or backhaul hydraulic cylinder 5 in fuel tank 1 by the utility model, forms oil
Case, hydraulic pump, the oily circulation loop of hydraulic cylinder closure, while realizing the effect that hydraulic recovery is utilized.
