Description

A kind of oil-free twin-tub air compressor machine
Technical field
The invention belongs to air compressor machine technical field, it is related to a kind of air compressor machine for improving compression ratio, refers in particular to a kind of oil-free twin-tub Air compressor machine.
Background technology
The operation principle of air compressor machine generally directly drives compressor by motor, bent axle is produced rotary motion, drives Connecting rod makes piston produce reciprocating motion, causes volume of cylinder to change.Due to the change of inner pressure of air cylinder, air is made by intake valve Enter cylinder by air cleaner (silencer), in compression travel, due to the diminution of volume of cylinder, compressed air is by row The effect of air valve, through blast pipe, check valve (check-valves) enters air accumulator, when pressure at expulsion reaches rated pressure 0.7MPa by Pressure switch is controlled and autostop.When reservoir pressure is down to 0.5--0.6MPa, pressure switch couples startup automatically.
Conventional air compressor machine, produces maximum pressure probably in 8.6Kg/cm in the market2, if it is desired to improve pressure Value is, it is necessary to improve compression ratio, and pressure rise can allow the density of gas to become big, and intermolecular distance also just diminishes, and temperature also can Rise, easily makes cylinder burst, in order to avoid the generation of accident, generally using two-stage compression by the way of improve pressure, have Body mode of operation is that gas enters in the first cylinder, after compression, into the second cylinder, passes through secondary further pressure The pressure value of gas is improved after contracting, then the gas after compression is passed through in air accumulator, the shortcoming of which is every grade of stream Amount is less than normal, reaches specified pressure value duration, efficiency is low.
The content of the invention
It is an object of the invention to provide it is a kind of by one stage of compression with regard to the oil-free twin-tub air compressor machine of pressure value can be improved.
The object of the present invention is achieved like this:A kind of oil-free twin-tub air compressor machine, including air accumulator and compression cylinder component, pressure Contracting cylinder component is made up of dual-axle motor and two cylinders, and two air cylinder structures are identical, and connected between two cylinders by connecting tube, Wherein, connecting rod is provided with the cylinder, the drive shaft connection of connecting rod one end and dual-axle motor, the other end is provided with piston, institute State and guide ring is provided between the end of connecting rod and piston, connecting rod reciprocating effect in cylinder can be improved by guide ring Rate, reduces abrasion, and the cylinder upper end is provided with valve plate, and the lower surface of the valve plate is provided with air-intake valve plate, and upper surface is set Have and limited block is provided with above outlet valve block, the outlet valve block, the stroke of the outlet valve block is less than the row of air-intake valve plate Journey, gas outlet when outlet valve block is opened, which is less than on the outside of air inlet when air-intake valve plate is opened, the cylinder body of the cylinder, to be provided with Radiating ribs.
Fan and crank are provided with order to accelerate to be provided with outside the radiating of cylinder, the cylinder in casing, the casing, The drive shaft of the dual-axle motor is connected with fan and crank, and the crank is connected with the connecting rod.
The piston can produce noise during acting, so being provided with noise reduction on the air inlet of the casing Device, air enters cylinder by muffler.
For security consideration, pressure control device is provided with the air accumulator, both are connected by off-load pipe, the pressure Force control device includes pressure gauge, pressure switch, safety valve and vent valve, and the safety valve and vent valve are arranged on the pressure In switch.When pressure at expulsion reaches rated pressure by pressure switch control and autostop, pressed when reservoir pressure is down to The automatic connection of power switch starts.
After air is compressed, intermolecular distance can diminish, and the aqueous vapor in air can also be condensed into liquid because of compression, described The bottom of the air accumulator is provided with draining valve, can periodically by air accumulator water discharge, it is ensured that air accumulator safety with And more useful spaces.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that:In the effective stroke of piston, due to outlet Gas outlet when valve block is opened is less than air inlet when air-intake valve plate is opened, and the gas flow into air accumulator diminishes, and is pressed The gas unit quantity of contracting is identical, so that the pressure that gas enters air accumulator increases, has reached the purpose for improving pressure value, and lead to The radiating of cylinder itself is crossed, effectively prevent and burst because cylinder block temperature is too high, improve security, and extends and makes Use the life-span.
