Kungong filter press teach you how to choose the frame filter filter diaphragm pump
Gap pump flow:
According to the volume of the plate-and-frame filter room, the moisture content of the dehydrated mud, and the concentration of the sludge before the plate frame, the amount of mud required for each dewatering operation of the plate frame is calculated. Then, make sure that you have a reasonable amount of time, such as 2-3 hours. Calculate traffic. Frame filter press manufacturers
Spacer pump material:
For ordinary biological sludge, the use of ordinary polypropylene material is more economical. Other special sludges should be based on the detailed sludge status and use the material of the diaphragm.
Things to watch for in the plan:
1. The pressure reducing valve and ball valve are installed on the intake line to facilitate viewing and conditioning of the flow and pressure of the diaphragm pump;
2. At the beginning of dehydration, the atmospheric pressure should be controlled at 2-3 bar. When the flow rate of water is increased, the surface air pressure will be raised and better dewatering results will be obtained.
3, the quality of sludge conditioning results play a decisive role; plate frame filter press manufacturers
Admit the fault of the diaphragm pump:
1, the pressure can not be improved, is limited by the pressure of the air source, 7bar to the lower limit;
2, music and pipe vibration, in the amount of Daewoo, a special distinction;
3, coherent in the screw pump, diaphragm life is short, easy to damage;
4, because the diaphragm pump flow is usually not too large, a small number of small pieces used;
Advantages of Receiving Gap Pumps:
1, the investment is low, the screw pump can be installed on demand conditioning flow, variable frequency or pressure adjustment valve, but also the need for supporting pressure sensors;
2. The task is reliable and complex. You can actively balance traffic with the addition of filtering resistance.
3, accounting for small air, installation is very easy. Frame filter press manufacturers
4, low cost, economical
