You know what is electromagnetic diaphragm metering pump accessories, mechanical diaphragm metering pump manufacturers division building to introduce ~ in fact, the working principle of electromagnetic diaphragm metering pump is electromagnetic push rod drives the gap in the pump head reciprocating motion, the pump head chamber cavity volume and pressure change, the change of the pressure in suction fluid valve and drain valve open and closed, complete liquid quantitative suction and discharge.

Standard accessories for electromagnetic diaphragm type metering pump:

1. One-way valve for the metering pump injection valve - connect pipe, and the backpressure of 1BAR to avoid liquid countercurrent may siphon.

2. Metering pump bottom valve - metering pump suction side with filter one-way valve, avoid liquid backflow and pump stop after the stop and no liquid air.

3. Metering pump suction side PVC hoses - usually the electromagnetic barrier metering pump standard with 2 meters of PVC suction pipe, the bright color contrast soft. It is not advocated that the suction process is too high. It is usually advocated for 2 meters of suction, which can be used at 4 meters height if used properly. (the cautious person takes the 2-meter course.)

4, metering pump drainage side PE pipe is usually the standard 3 m should be PE, white contrast hard without losing the flow rate of the fluid outlet (if with a hose PVC suction fluid metering pump flow will become smaller, because the PVC hose scalability compared easily swell) resistant to acid and alkali liquid usually.

Electromagnetic diaphragm type metering pump optional:

1. Multi-function valve for metering pump - usually multi-function valve, four-function valve, five-function valve, usually include: exhaust valve, relief valve, relief valve, back pressure valve, etc. The accuracy of the electromagnetic metering pump can be affected by the export pressure, especially between 0-10 bar. In addition, the backpressure of the drug to avoid the siphon phenomenon. The metering pump operates under the back pressure condition. It needs to avoid excessive pressure, and then the metering pump or system may be damaged. The utility valve is designed to deal with the above series of problems. The multi-function valve body product is small, with the electromagnetic metering pump matching device is brief and convenient.

2. The metering pump with back pressure valve - back pressure valve is used to insist that the metering pump outlet has a constant pressure to invent the excellent working environment for the metering pump and improve the operation function of the metering pump.

3. The safety valve of the metering pump is designed to ensure that the metering pump does not damage the metering pump due to the over-pressure of the pipe, and the relief valve will take the active relief when the pressure of the pipe is too high.
