Background technique
The control that has traditional air compressor now is the control mode that adopts pressure regulator valve (being called gas control) or pressure switch (being called automatically controlled) according to its concrete operating mode, the former can open when the air container internal air pressure reaches certain value and make the air compressor off-load being provided with one on the air container of air compressor, and can automatically reset pressure regulator valve when pressure drops to certain value, when pressure regulator valve is in open mode, air compressor (motor) is in the no-load running state, and after pressure regulator valve resetted (cutting out), air compressor (motor) was in the working state of heavy duty once more; The pressure switch that the latter adopted then is when air pressure reaches certain value, and motor power is cut off in the pressure switch action, and air compressor is shut down, and pressure drops to one when in fact being worth, and pressure switch resets and makes air compressor (motor) recover running.In actual use because the variation of various sector applications field difference and operating mode, often bring energy waste or burn motor because of the frequent starting of motor because of the long no-load running of air compressor, for overcoming above-mentioned deficiency, people are constantly adopting a kind of gas in the practice---automatically controlled compound mode, promptly on an air compressor, pressure regulator valve and pressure switch are housed simultaneously, one manual switching valve is set between the two, if air compressor no-load running overlong time, just switch to automatically controlled mode, if it is too frequent that air compressor starts, just switch to the gas control mode, but this method because of bothering, the difficult to calculate and frequent manual switching of applying working condition is difficult to be widely used.
Summary of the invention
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of and can judge operating mode and corresponding conversion blowing model automatically, integrated degree is high and assemble the automatic controller of air compressor easily.
The technical solution of the utility model is: a kind of automatic controller of air compressor, be characterized in comprising that the two-bit triplet solenoid valve, the relief arrangement that are connected with air compressor gas holder gas circuit reach the magnetic switch that is conducted with motor, between two-bit triplet solenoid valve, relief arrangement and magnetic switch, be provided with the pressure control device that the may command air compressor enters the operating mode that adapts with load behavior automatically.
The further technological scheme of the utility model is: above-mentioned pressure control device is made up of pressure switch and control circuit, wherein: above-mentioned pressure switch is made up of diaphragm, spring, pressure adjusting screw and a pair of circuit contact, described diaphragm arrangement in suction port that gas holder links to each other near, described circuit contact and control circuit are conducted; Above-mentioned control circuit is made up of power supply module, CPU control computing and output, wherein has two outputs to be connected with two-bit triplet solenoid valve, magnetic switch respectively; Above-mentioned control circuit can be judged the action of load state and output signal control two-bit triplet solenoid valve or magnetic switch according to the signal of pressure switch output.
The utility model is owing to adopted the two-bit triplet solenoid valve that is provided with on the air compressor gas circuit, relief arrangement and the magnetic switch that is conducted with motor, particularly at the two-bit triplet solenoid valve, the may command air compressor that is provided with between relief arrangement and the magnetic switch enters the pressure control device of the operating mode that adapts with load behavior automatically, make air compressor when work, can regulate its operating mode automatically according to different operating modes, so not only can cut down the consumption of energy greatly, and can reduce the ordinary knee-action of relief arrangement and the loss that causes, improved the utilization efficiency and the quality of air compressor.
The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment
The utility model as shown in Figure 1 and Figure 2, a kind of automatic controller of air compressor, be characterized in comprising that the two-bit triplet solenoid valve 1, the relief arrangement 2 that are connected with air compressor gas holder 7 gas circuits reach the magnetic switch 4 that is conducted with motor 3, between two-bit triplet solenoid valve 1, relief arrangement 2 and magnetic switch 4, be provided with the pressure control device that the may command air compressor enters the operating mode that adapts with load behavior automatically.Above-mentioned pressure control device is made up of pressure switch 5 and control circuit 6, wherein: above-mentioned pressure switch 5 is made up of diaphragm 51, spring 52, pressure adjusting screw 53 and a pair of circuit contact 54, described diaphragm 5 is arranged near the suction port that links to each other with gas holder 7, and described circuit contact 54 is conducted with control circuit 6; Above-mentioned control circuit 6 is made up of power supply module, CPU control computing and output, wherein has two outputs to be connected with two-bit triplet solenoid valve 1, magnetic switch 4 respectively; Above-mentioned control circuit 6 can be judged the action of load state and output signal control two-bit triplet solenoid valve 1 or magnetic switch 4 according to the signal of pressure switch 5 outputs.Above-mentioned pressure switch 5 and control circuit 6 are arranged in the same housing, and described two-bit triplet solenoid valve 1 is arranged at the outside of housing.Above-mentioned two-bit triplet solenoid valve 1 is the two-bit triplet normal closed type, and wherein the main passage of two-bit triplet solenoid valve 1 is connected between gas holder 7 and the relief arrangement 2, and subaisle is connected between relief arrangement 2 and the atmosphere.Above-mentioned relief arrangement 2 is one can make gas drain into the safety valve of atmosphere when superpressure automatically.
Entire work process of the present utility model (as shown in Figure 3) is achieved in that connects the power supply start, if the air demand of air engine is less than the demand of gas equipment, then air compressor heavy duty running always, if the air demand of air compressor is greater than the demand of gas equipment, then gas holder 7 internal air pressures can rise, when pressure in the air compressor air storage tank 7 rises to the CLV ceiling limit value of pressure switch 5 settings, its circuit contact 54 disconnects, this switching signal arrives two-bit triplet solenoid valve 1 after control circuit 6 is handled, two-bit triplet solenoid valve 1 gets electric A---and P connects, pressurized air reaches relief arrangement 2 in the gas holder 7, relief arrangement 2 actions, air compressor enters no-load running, control circuit 6 picks up counting simultaneously, as passing through a certain set time as 5 minutes, pressure does not drop to the lower limit of pressure switch 5 resets in the air compressor air storage tank 7, then control circuit 6 sends signal cut magnetic switch 4 coil circuits air compressor is shut down, also cut off simultaneously two-bit triplet solenoid valve 1 coil current, A---P disconnects, A---R conducting with the gas release in the relief arrangement 2 to atmosphere in order to light-load starting air compressor next time, prolong 2 working lifes of relief arrangement.Turn round under heavy duty (automatically controlled pattern) pattern that realized promptly that air compressor is in heavy duty---shutdown---; For example in 5 minutes in the air compressor air storage tank 7 pressure drop to the lower limit of pressure switch 5 resets, then pressure switch 5 its circuit contact 54 conductings that reset, this switching signal arrives two-bit triplet solenoid valve 1 after control circuit 6 is handled, two-bit triplet solenoid valve 1 dead electricity A---P disconnects, A---R conducting with the gas release in the relief arrangement 2 to atmosphere, relief arrangement 2 gases out of hand, air compressor recovers the heavy duty running, so move in circles, the energy waste that long-time no-load running (gas control) is caused when both having avoided without gas, avoided again continuous during with gas (automatically controlled) the too frequent startup of air compressor burn motor.
