Abstract

The invention discloses a hydraulic operated gas compressor, which comprises a hydraulic pump, a liquid filter, a cylinder, a check valve, a gasholder, an electromagnetic valve, a liquid level switch, a gas-liquid separator and a liquid storage tank, wherein the liquid storage tank is capable of being omitted under special circumstances, the cylinder is a closed container, the upper portion of the cylinder is equipped with an air inlet check valve, an air outlet check valve and the liquid level switch, and the lower portion is equipped with a liquid inlet electromagnetic valve and a fluid discharge electromagnetic valve. When the hydraulic operated gas compressor begins to operate, liquid which is driven by the hydraulic pump enters into the cylinder from the lower portion, gas is upward compressed, when the liquid level in the cylinder lifts to a triggering position of the liquid level switch, and a triggering system reverses. The cylinder discharges the liquid and intakes, and at the same time other cylinder begins to compress the gas until the triggering system of the liquid level switch reverses against. The compressing of the gas is achieved by repeat movement of the liquid lever in the cylinder. Mechanical friction, oil pollution and big noise do not exist during the system works, the compression efficiency is high, and the gas flow is large.

Description

Hydraulic gas compressor
Technical field
The present invention relates to a kind of hydraulic gas compressor.
Background technique
Used gas compressor generally is by the reciprocating pressurized gas that obtains of the device of piston in the motor drives cylinder or similar piston.Because between piston and cylinder body mechanical friction is arranged, noise is big at work, efficient is low for compressor, and need to dispose the lubrication system that makes compressor easily and be infected with greasy dirt on every side.
Summary of the invention
The objective of the invention is for overcoming a kind of hydraulic gas compressor that above-mentioned deficiency is made.Moving up and down in cylinder with liquid level replaces reciprocating motion of the pistons to obtain pressurized gas, and it is little to have a noise, efficient height, the advantage that flow is big.
The objective of the invention is to be achieved through the following technical solutions:
A kind of hydraulic gas compressor comprises oil hydraulic pump, liquid filter, cylinder, check valve, gas holder, solenoid valve, liquid-level switch, gas-liquid separator and liquid storage pool.The quantity of cylinder is at least one; Cylinder is a seal container, and the lower end of cylinder is provided with into, draining solenoid valve; The upper end of cylinder is provided with inlet and outlet check valve and liquid-level switch; The cylinder upper end is communicated with through pipeline with gas holder; Oil hydraulic pump is connected through pipeline with liquid inlet electromagnetic valve, and draining solenoid valve is communicated with through pipeline with liquid storage pool.During the system entry into service, the highly pressurised liquid of being sent here by oil hydraulic pump enters make progress gas in the compression cylinder of left cylinder bottom through liquid inlet electromagnetic valve, and compressed gas enters gas holder through exhaust check valve and gas-liquid separator; When liquid level is raised to the liquid-level switch position, the liquid-level switch action, actuating signal is closed liquid inlet electromagnetic valve and is opened the draining solenoid valve discharge opeing simultaneously; Gas sucks cylinder through the air inlet check valve.Aforementioned in addition liquid-level switch actuating signal is also closed right inblock cylinder liquid electromagnetic valve simultaneously and is opened right cylinder liquid inlet electromagnetic valve feed liquor; Like this, system just is inverted to that right cylinder begins pressurized gas, left cylinder begins discharge opeing, and this process lasts till that always liquid level rises to right cylindrical liquid bit switch and is triggered, and system reverses and gets back to original state.So utilizing in the cylinder liquid level to pump compresses gas.
When liquid was ordinary water, liquid storage pool can be the pond, also can be to be used as liquid storage pool to reservoir, rivers and lakes, ocean greatly.
Liquid storage pool in the technique scheme can be simplified.Be an improvement project of no liquid storage pool below:
This improvement project comprises oil hydraulic pump, cylinder, check valve, gas holder, solenoid valve, liquid-level switch, gas-liquid separator, liquid filter; The quantity of cylinder is that even number is provided with in pairs so that alternation; Cylinder is a seal container, and the lower end of each cylinder is provided with into, draining solenoid valve; The upper end of cylinder is provided with inlet and outlet check valve and liquid-level switch.The cylinder upper end is communicated with through pipeline with gas holder; Oil hydraulic pump with advance accordingly, draining solenoid valve is connected through pipeline.Describedly advance, draining solenoid valve can be divided into two groups of working staties: first group of working state, with first cylinder draining solenoid valve that links to each other and the liquid inlet electromagnetic valve unlatching that links to each other with second cylinder in the cylinder, other advance, draining solenoid valve are closed, liquid flows to second cylinder when second group of working state by first cylinder through oil hydraulic pump, the liquid inlet electromagnetic valve that links to each other with first cylinder is opened with the draining solenoid valve that links to each other with second cylinder, other advance, draining solenoid valve are closed, and liquid flows to first cylinder by second cylinder through oil hydraulic pump; By the horizontal liquid level in the cylinder gas is upwards compressed; Compressed gas enters gas holder through exhaust check valve and gas-liquid separator; When liquid level in the cylinder was raised to the liquid-level switch position, liquid-level switch triggered, and two groups of solenoid valves are reversed simultaneously, like this, make each to cylinder and advance accordingly, the draining solenoid valve alternation.
Further, can link to each other with cylinder by a common pipeline with the solenoid valve that same cylinder bottom directly links to each other, thereby reach the purpose of simplifying pipeline.
The electronic control system that is used for the liquid level alternation can be made up of relay, perhaps by programmable device or computer control.
Technique effect of the present invention is: hydraulic gas compressor is to utilize liquid level alternate replacement reciprocating motion of the pistons in the cylinder, realizes the compression to gas; The alternate of the liquid level in the cylinder is by hydraulic pump drive, and the automatic control cylinder working in reciprocating mode of electron inversion system is arranged; So do not have mechanical friction whole system noise minimum in the course of the work, and sealing is fabulous between liquid level and cylinder, does not have any gas leakage gap; The cylinder working in reciprocating mode can be continuous the pressurized gas that big flow is provided, in the working efficiency that has improved gas compressor aspect the thermal loss that reduces sliding friction, hydraulic gas compressor does not have components of machine such as piston, belt pulley, crank, so lubrication system need be set, make gas compressor and surrounding environment avoid the oily consumption and the pollution of lubricated greasy dirt.
Because the cross-section area of liquid level is exactly the horizontal cross-sectional area of a seal container in the present patent application, it can be accomplished easily than long-pending big many orders of magnitude of high accuracy mechanical piston cross-section, so this hydraulic gas compressor can be made the gas compressor of super-flow.
