What details should be paid attention to when using metering pumps
Trouble is often encountered when removing the old diaphragm. Now provide some additional advice on how to remove the old diaphragm. After the pump head is loosened, before removing the pump head, adjust the stroke length to the 0% position. The metering pump can ensure that the solenoid shaft has a satisfactory pressure and keep its connection stable, so that the diaphragm can be unscrewed.
Pull the fluid end outward to disengage the screw from the socket. Grasp the liquid end and rotate it counterclockwise. With a little resistance, the diaphragm can be unscrewed. The metered chemicals may crystallize on the hydraulic end, causing the ball and seat of the check valve to fail to operate normally. There may be a gas leak on the suction side of the metering pump. The suction side connector of the fluid end may be missing an O-ring or the suction valve connection may be loose.
Check whether the motor of the metering pump is working. If it is not working, there is a problem with the motor or electrical control circuit. Clarification: Under normal circumstances, the circuit of the chlorine dioxide generator is equipped with an overload protection device, so that the motor does not work and the motor is not damaged. At this moment, you need to open the square control box inside the square controller inside the chlorine dioxide generator. panel.
Press the blue button (reset button) on the thermal relay on the right side of the bottom row, and the metering pump can work normally; if the metering pump is still not operating normally, a qualified electrician is required to comply with the chlorine dioxide supplied by the manufacturer See the related circuit for the generator circuit diagram. Check whether there are impurities in the medicine inlet pipe or the medicine pipe that are blocking the pipeline.
