Back with a cold coolant (water, oil, etc.) directly from the back of the stationary ring ring static cooling cooling mode, the cooling effect is good, can be directly cooled rapidly on the back of the stationary ring, called quenching, it is usually combined with the use of flushing .
Pneumatic diaphragm pump failure and remove, but also helps to prolong life:
A pump in operation, but the flow is too low how else
1. Check whether the pump free of plaque like, adjust the inlet pressure of compressed air. Reduce the operating speed of the pump to adjust the viscosity and concentration of large liquid.
2. Check valve ball is stuck. If the delivery of the liquid with the valve ball materials do not coincide. The ball will swell. Replace the appropriate material ball valve and valve seat.
3. Check whether the inlet pipe is blocked.
Second, the pneumatic diaphragm pump can not start or slow approach
1. Check the filter, regulator and lubricator and the air inlet filter if clogged.
2. Check whether the valve was stuck impurities, please remove and clean the valve, piston valve inside view of whether there are scratch marks. If the piston surface bright and not pure black, indicating the need to replace worn piston and "O" ring. Injury marks. Please replace the new
3. Check the spindle and the "O" rings if there are signs of scratches, wear and flattened, replace if damaged.
Fourth, the export contains a large number of bubbles in the liquid off where inspection
1. Check for diaphragm rupture.
2. Check the pump and piping for leaks.
Third, the liquid leaking from the gas chamber discharge outlet how to deal with
1. Check for diaphragm rupture.
2. Inspect the diaphragm is correctly installed and locked.
