1. The temperature of the material conveyed by the pneumatic diaphragm pump should be less than 100℃ to protect the normal use of the diaphragm.
2. After the pneumatic diaphragm pump is in good condition after the system is checked before starting up, the pump head is filled with the material to be transported so that the material can flow into the pump by itself.
3. Turn on the power, start the drag motor of the speed changer, and then adjust the fine-tuning knob of the slip clutch control device to make the crankshaft rotate.
4. Remove the upper cover of the control valve, and press the upper end of the oil supplement valve core several times by hand to remove the air in the hydraulic chamber until no bubbles appear. At this time, the hydraulic oil is filled with the hydraulic chamber and normal operation can begin.
5. When using the pneumatic diaphragm pump, the pressure of the control valve should be the same as the pressure of the nozzle, and there should be no excessive pressure difference before the diaphragm.
6. The temperature of the feed pump, the pressure of the feed liquid and the operation of the pump should be checked frequently during use of the pneumatic diaphragm pump.
7. When the pneumatic diaphragm pump stops, first turn the slip clutch control device to the ‘0’ position, and the crankshaft stops rotating.
8. If the pneumatic diaphragm pump is out of service for too long, the remaining material in the pump head needs to be drained to prevent the ball valve from blocking the inlet and outlet and rusting.
9. Pneumatic diaphragm pumps generally use 40# oil, and the original oil should be cleaned when changing the oil.
10. Always maintain the cleanliness of the air diaphragm pump and the good insulation of the motor, and make timely records of operation, shutdown, accidents, and maintenance.
