Diaphragm pump dosing machine manufacturer introduces the repair of pneumatic diaphragm pump

Before disassembling the stainless steel diaphragm pump, mark the brake air chamber and fluid chamber on the display side to facilitate subsequent assembly and operation.

Use objects or wrenches to fix the outer straightening plate of the pulse damper to set the boundary to separate the diaphragm device from the device. Then loosen the diaphragm device by turning it clockwise. After removing the outer straightening plate of the pulse damper, remove The shaft is removed from the machine.

Use a quick clamp (raised wooden board) to separate the shaft from the pulse damper equipment, and check whether the shaft, straightening splint, and pulse damper are damaged or corroded.

The equipment is running from process 6 to process 1, but the flow rate is small or no liquid is discharged at all:

Check whether the inlet joint of the stainless steel diaphragm pump is completely tight and leak-proof, especially the clamp joint adjacent to the inlet end valve ball needs to be tightened;

The air valve of the stainless steel diaphragm pump of the diaphragm pump dosing machine is frozen: check whether the air moisture content is too high and whether there are bubbles at the inlet and outlet of the equipment gas drying equipment pump;

Check whether the pulse damper is broken and whether the clamp joints are tight, especially the imported pipe clamp joints;

The product is discharged from the air sewage outlet: check whether the pulse damper is broken, check whether the pulse damper and the straightening plate in the table hold the valve on the shaft and make a rattling sound, and increase the pump lift at the outlet or inlet.

Guide to disassembling and reassembling the stainless steel diaphragm pump: Warning: Before repairing the stainless steel diaphragm pump, first unplug the gas source pipeline from the stainless steel diaphragm pump, and discharge the air pressure in the stainless steel diaphragm pump. Unplug all docking stainless steel diaphragm pumps The inlet and outlet pipes are then used to discharge the liquid in the stainless steel diaphragm pump into an appropriate container.

Wear a protective hat, myopia glasses, and rubber gloves if the stainless steel diaphragm pump does not run at all or runs slowly:

Check whether there is any residue on the air filter or air purification equipment at the air inlet.

Check the condition of the sealing parts of the central body. If damage is not allowed, the sealing effect will not be achieved, and the gas will be discharged from the gas inlet and outlet. Due to its special structure, please only use the GLYD ring.

Check whether the movement in the air valve of the diaphragm pump dosing machine is normal.
