Abstract
A hydraulic drive air compressor comprises an oil pump, a fluid path reversing control valve, a compressor body, a piston, an air storage tank, etc. The compressor body is divided into two hydraulic oil cavities and four air cavities in bilateral symmetry through a compressor piston and a partition board; two piston control sections are arranged on two sides of a middle piston of the compressor body respectively; and two control cavities matched with the piston control sections are arranged on the partition board sides of the hydraulic oil cavities, for controlling automatic reversing. The working principle of the hydraulic drive air compressor is that: hydraulic oil generated by the oil pump enters into the left and right hydraulic oil cavities of the compressor alternately under the control of the fluid path reversing control valve, to push the piston to move to the left and to the right, so that the bulks of the two air cavities are reduced and the air in the air cavities is compressed and discharged into the air storage tank, at the same time, the bulks of the other two air cavities are increased and the air is intaken by an air intake filter and an air intake one-way valve. Since no lateral pressure exists between the piston and the compressor body, the friction loss is small, the piston stroke is greater than that of a common compressor, and the air leakage and compression clearance is small; and the hydraulic drive air compressor has higher efficiency compared with a traditional compressor.
Description
Technical field
The utility model belongs to the air compressor technical field.
Background technique
Now, piston type air compression quilt is the every field of applicable industry widely, in this compressor operating process, owing to produce bigger lateral force between piston and the cylinder wall, and the frictional loss that produces, and, cylinder wall, piston equitemperature are raise because of friction generates heat, the temperature rising makes suction again, and when gases are heated, they expand, further strengthened the efficient power consumption of compressor.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic driving air compressor, and this machine adopts oil hydraulic pump to produce power, promotes piston to gas compression by hydraulic oil; Eliminated the lateral force between piston and the cylinder wall theoretically, made that air compressor structure is simple more, efficient is higher.
Structure of the present utility model is made up of oil pump, fuel tank, liquid road reversing control valve, compressor body, gas holder etc.Compressor body wherein is separated into three sections with two dividing plates, and piston is made up of an intermediate piston (respectively there is a piston control section intermediate piston both sides) and two end pistons; Piston and dividing plate are divided into symmetrical six chambeies with compressor body, are two hydraulic fluid chambers, four air cavitys.Be shaped on two control chambers in the hydraulic fluid chamber bulkhead sides, cooperate, the road reversing control valve automatic reverse of control liquid with the piston control section; Control oil channel is established one-way valve and liquid road reversing control valve control valve, to guarantee liquid road reversing control valve two definite positions is arranged.
Working principle: when oil pump was started working, liquid road reversing control valve was in position, a left side under the effect of spring; The hydraulic oil that oil pump produces enters the hydraulic fluid chamber on the compressor body left side by liquid road reversing control valve, promotes piston and moves right, and the volume of two air cavitys is reduced, and gas wherein is compressed and enters in the gas holder.The volume of two other air cavity becomes big simultaneously, and air sucks through air intake filter, breather check valve.When right piston control section entered control chamber, control chamber pressure sharply increased; Hydraulic oil makes the reversing control valve commutation of liquid road by pilot line, is in right position; The hydraulic oil that oil pump produces enters the right hydraulic fluid chamber of compressor body by liquid road reversing control valve, promotes piston to left movement, and the volume of two air cavitys is reduced, and gas wherein is compressed; Pressurized air is entered in the gas holder.The volume of two other air cavity becomes big simultaneously, sucks air.When the left piston control section entered control chamber, hydraulic oil made liquid road reversing control valve control valve be in right position, and the control oil in the reversing control valve of liquid road flows back to fuel tank, and pressure disappears; Liquid road reversing control valve core is got back to position, a left side under the effect of spring, realize automatic reverse.Owing to do not have lateral pressure between piston and the compressor body, frictional loss is very little, have the efficient higher than traditional compressor.
