Pneumatic diaphragm pump removal instructions
Pneumatic diaphragm pump after a long time there will be a failure, the need to disassemble the device in the process of troubleshooting, the wrong way to disassemble may cause irreparable damage to the device, thereby affecting all aspects of the work . Xiaobian following a brief introduction to the pneumatic diaphragm pump disassembly order it. 1, before removing the pneumatic diaphragm pump, the left and right sides of the gas chamber and liquid chamber were marked to facilitate subsequent reassembly action. 2. Use a wrench to loosen the small clamp connecting the outlet pipe to the liquid chamber. Remove the outlet pipe to see the ball and valve seat. Remove the ball and seat and check for other wear and tear on the pump. Chemical corrosion, cracks, etc. phenomenon. 3, use a wrench to separate the liquid chamber and the pump intermediate, remove the liquid chamber to see the diaphragm and membrane splint. 4, using tools or wrenches fixed diaphragm left and right edges of the outer plate, the diaphragm device and the intermediate body separately. Then turn clockwise to loosen the diaphragm assembly. After removing the diaphragm from the clamp, remove the shaft from the intermediate body. 5, using the clamp (padded wood) the shaft and the diaphragm device separate, check the shaft, plywood, diaphragm damage and corrosion. 6, the installation from step 5 to step 1 after the assembly problems here Xiaobian also mentioned by the way. Pneumatic diaphragm pump action, but the flow is small or no liquid out: 1. Check the cavitation of the pump to reduce the speed of the pump to allow liquid to enter the chamber. 2. Check if the valve ball is stuck. If the operating fluid is incompatible with the pump elastomer, the elastomer will swell. Please replace the appropriate material elastomer. 3. Check the pump inlet connector is completely tight leak, especially near the entrance of the valve ball to be locked. Pump air valve freeze: Check the compressed air moisture content is too high, the installation of air drying equipment Pump outlet bubble generation: Check the diaphragm is broken, check the clamp is locked, especially the inlet pipe clamp. Product outflow from the air outlet: Check the diaphragm is broken, check the diaphragm and the internal and external clamp on the shaft whether the valve cling to rattle: increase the export or inlet lift. Finally, before the pneumatic diaphragm pump is repaired, remove the air source tubing from the pneumatic diaphragm pump and vent the air pressure in the pneumatic diaphragm pump. Remove all tubing connecting the inlet and outlet of the pneumatic diaphragm pump and drain the fluid in the pump into a suitable container. Wear protective caps, eyeglasses and gloves to protect it.
