When starting motor 22 once more, because pneumatic tube 26 gas inside pressure equal or are slightly larger than gas pressure in the air reservoir 28, and the gas pressure of this moment is still much larger than ambient atmos pressure, therefore pneumatic cylinder 21 when starting because of the effect of noninertia power, very difficult when starting, especially when the gas pressure in the air reservoir 28 is still very big, so should be earlier with the discharging earlier of the gas in the pneumatic tube 26.
In order to improve gas pressure (residual voltage) problem in the above-mentioned pneumatic tube 26, one solenoid valve can be connected in connecting tube 42 and the pressure switch 41, when air compressor shuts down, solenoid valve is in open mode and the gas in the connecting tube 42 is discharged, and therefore can in the lump the gas in the pneumatic tube 26 be discharged.
The purpose that the conventional air compressor is provided with connecting tube 42 is whether to reach the maximum high-voltage point that pressure switch 41 sets in order to make pressure switch 41 survey the air inlet gas pressure, if reach the residual gas of then closing in motor 22 and the eliminating pneumatic tube 26.
The tradition compress control method is undertaken by the air inlet gas pressure, rather than undertaken by air reservoir 28 gas inside pressure.Because the conventional air compressor can't be crossed at air reservoir 28 internal gas pressures and control starting motor 22 when hanging down.But the gas pressure of air inlet simultaneously is not definitely identical with air reservoir 28 gas inside pressure, still has certain error, therefore can't realize accurate control with the air inlet gas pressure.In addition owing to showing the maximum high-voltage value of being transferred on the pressure switch 41, so the user can't correctly set the maximum high-voltage point value.
The object of the present invention is to provide a kind of air compressor of accurately controlling motor or pneumatic cylinder running by the air reservoir internal gas pressure.
The object of the present invention is achieved like this, promptly adopt a kind of air compressor, it mainly comprises motor, pneumatic cylinder, pneumatic tube, outlet pipe, air inlet connecting head, exhaust connector, air reservoir, and pressure gauge, wherein: pneumatic cylinder can be connected with air reservoir by pneumatic tube and air inlet connecting head, and outlet pipe can be connected with air reservoir by exhaust connector;
Motor can drive the pneumatic cylinder motion, and pneumatic cylinder can be squeezed into the gas in the external world in the air reservoir by pneumatic tube, makes the gas pressure of the interior gas pressure of air reservoir greater than the external world;
There is an one-way cock air inlet connecting head inside, make ambient atmos can enter air reservoir inside through one-way cock, and the air reservoir gas inside can't be discharged through one-way cock;
Pressure gauge can show air reservoir gas inside force value;
It is characterized in that:
Above-mentioned air compressor comprises an electromagnetic valve switch, this solenoid valve keeps closed condition when motor or pneumatic cylinder running, the pneumatic tube internal gas can't be communicated with the external world, and when motor or pneumatic cylinder do not turn round, continue to open or a certain period when being open mode when this solenoid valve, the pneumatic tube internal gas just can keep communicating with the external world or a certain period communicates;
Above-mentioned pressure gauge is the pressure gauge of exportable control signal, and control signal can directly or indirectly be controlled the running of motor and solenoid valve.
