I. product overview

 

The spray system is mainly composed of pneumatic piston lubrication pump, pneumatic pressure reducing valve (with filter), two three-way pneumatic directional valve, two two-way solenoid valve, liquid level alarm switch, oil filter, flexible nozzle and so on. Pneumatic piston lubrication pump, using compressed air as the power source; Pneumatic pressure reducing valve (with filter) to remove impurities and moisture from the air source and adjust the pressure. The pulse controller controls the opening and closing of the two three-way directional valve to complete the reciprocating movement of the piston. Adjust the frequency of the piston by adjusting the knob on the controller to achieve the best spray effect. Pump built-in low oil level alarm switch.

 

Ii. Working principle

 

The pulse controller controls the switch of the two three-way solenoid valve. The opening and closing of the air circuit makes the piston in the cylinder body reciprocate. Meanwhile, the gas enters the cylinder, and the piston moves down and is filled with oil. The air circuit is disconnected, and the piston is reset under the action of the spring force to absorb oil. The pressure oil merges with the compressed air at the nozzle and sprays out the mist.
