Description
Technical field
The present invention relates to diesel driven screw air compressor field, and in particular to a kind of diesel driven air screw
Compressor control screen.
Background technology
In the wild where no mains-supplied, need to use portable air compressor, it is larger in construction duty ratio
Rock drilling, the occasion such as open a mine, open a way, are usually used the portable air compressor of diesel driven.
According to the difference of air compressor internal structure, air compressor in the market is broadly divided into air screw
Compressor, piston type air compressor, centrifugal air compressor etc..It is non-that centrifugal air compressor is mainly used in gas consumption
Often big occasion, general enterprises application are little.Piston type air compressor equipment investment is low, and many past enterprise all adopts, but
It is that gas producing efficiency is poor, is just progressively replaced by screw air compressor.
For mobile screw formula air compressor, when air compressor starts, atmospheric control makes air inlet valve position
In the state opened, duty ratio when this means that compressor start is larger, and this requires to send out from diesel oil than larger
The power input of motivation.And at this moment Diesel engine is to be slowly increased to rated speed from zero velocity, in Diesel engine also not
When reaching rated speed, larger moment of torsion is easy to so that engine misses.The Diesel engine that this defect is matched in equipment
So good startability or embodiment can not protruded under the more disappointing operating mode of low-temperature startup performance, so as to affect equipment
Normal operation.And at present domestic mobile screw formula air compressor is for this problem, one kind is with apolegamy diesel oil
Reserve more surpluses to solve during engine, this mode not only increases development cost, wastes resource.For starting
It is that intake valve open in usual is modified to normally closed type that the difficulty in starting problem of machine also has a kind of way, but this needs atmospheric control
Control realization, this change can cause Diesel engine oil consumption to raise, and are equally unfavorable for economizing on resources and improve product quality.
As above, in prior art, be by the atmospheric control of air compressor come drive Diesel engine speed governing, with
And air inlet valve regulation aperture is driven, so as to realize the control of air compressor output pressure and tolerance.Specifically, pressure all the way
Gas enters the speed governing cylinder of Diesel engine, controls the output speed of Diesel engine, and pressure all the way by speed governing cylinder
Gas then enters intake valve master cylinder, carries out aperture control by intake valve master cylinder to intake valve.Atmospheric control is controlled
There are problems that governing speed is slow, control accuracy is low.

Send rotating speed control instruction to the ECU to improve rotary speed of diesel engine, while electric controller is supervised by the baroceptor
Air pressure in the gas tank is surveyed, when air pressure reaches air pressure setting value, makes Diesel engine stop speed-raising；
When normally continuously using gas, gas consumption is little when big when possible, and now electric controller adjusts Diesel engine turn by the ECU
Speed adjusting air pressure in the gas tank so that in gas tank stable gas pressure in air pressure setting value, now screw air compressor
Outlet and gas equipment reach balance with gas, the equilibrium of supply and demand can more energy-conservation, in stable gas tank air pressure can also protect with
The tank connected gas equipment of gas is without prejudice, it is normal continuous with gas when make the intake valve standard-sized sheet；
During interruption gas, when in gas tank, air pressure exceedes air pressure setting value, electric controller preferentially declines diesel engine by the ECU
Reducing air pressure in gas tank, rotary speed of diesel engine can go straight down to idling to machine rotating speed, if air pressure in gas tank during idling
Still above air pressure setting value, then electric controller passes through intake valve driving plate reduces the aperture of the intake valve, until gas in gas tank
Pressure reaches air pressure setting value, and it is zero that the aperture of intake valve can drop to aperture according to need.
