The unique performance of the diaphragm pump and good versatility and interchangeability make it especially suitable for the chemical industry, light industry, food industry process pump update, lower operating costs, easy maintenance and operation, in order to improve economic efficiency. Common diaphragm pump propulsion liquid control system improvements are as follows: If the diaphragm pump propulsion liquid cavity too little fluid, the magnet will move to the trigger ZSL Department, the trigger output a pulse signal to the PLC control box. The PLC will output a signal to open the filler valve HV1, 2 or 3 and push the liquid into the pusher chamber. If the diaphragm pump to promote too much liquid in the liquid chamber, trigger ZSH also output a pulse signal to the PLC control box, this time the discharge valve HV5, 6 or 7 open, the propellant liquid will be discharged into the liquid chamber. If the diaphragm pump advancing liquid system is faulty, the charge or discharge valve continues to fire for more than 3 min, the PLC will output a fault signal. The injection of liquid above the discharge is automatic, but the diaphragm pump at run time occurred due to triggers, internals and other reasons that automatic liquid injection process out of control, to overhaul only parking, in order not to bring loss of production After careful consideration, the decision to use manual injection of oil, due to lack of experience, the first injection, the promotion of liquid chamber on the exhaust valve is not open, resulting in too much liquid filling, so that the diaphragm is damaged. On the basis of summing up the experience of failure, manually re-oiling, open the exhaust valve to promote the cavity discharge stroke pressure is stable as a sign of fullness.
