The Evacuation-Proof Protection Device for PCP studied by Dongying Orientsun Electric Company Ltd., is installed on the tubing, it will stop the motor when no fluid is tested for 30 seconds. This device has thoroughly solved the problems of PCP burnout due to the evacuation and large gas rate.
1. Adopt stainless steel, refraining from the corrosion of the fluid.
2. Separate the fluid in the tubing from the testing parts, be used for the tubing under 10MPa.
3. Separate from the air with no part damaged.
1. Ambient temperature: -30℃～+50℃（it should adopt heating and holding treatment when the temperature is less than zero degree.）
2. Air humidity: less than 95%（+25℃）
3. Protection level: IP34.
4. Altitude: less than 2000m.
1.working voltage: 5-36VDC
1.controlling current: 0.5A
3.flow range: 0-300m3 /day
It should adopt heating and holding treatment when the temperature is less than zero degree, avoiding damaged due to the frozen circumstance.
