1. Select the switch to move to the manual position.
2. Open the exhaust valve of the compressor.
3, slide valve pointer in the "0" position, that is, 10% load position.
4, according to the electric heating button, the heat lamp is light, the oil temperature rose to 40 °C, press the heating stop button.
5. Press the water pump start button to supply water to the oil cooler.
6. Press the oil pump button to start the oil pump, and the oil return solenoid valve C will open automatically.
After 7, 5 seconds to 10 seconds, the pressure difference between oil pressure and exhaust pressure can reach 0.4 ~ 0.6Mpa, according to the host
Start button, compressor starts, bypass solenoid valve A will open automatically, return solenoid valve C
8. Observe the inspiratory pressure gauge and gradually open the inspiratory stop valve.
The compressor enters the running state, the A valve closes automatically, and the oil pressure regulating valve is adjusted to make the oil pressure (injection)
The difference between pressure and exhaust pressure is 0.15～0.3Mpa
9, After the compressor operation pressure and temperature difference are normal, check the sealing of each moving part, temperature measurement and pressure measurement point.
