maintenance of wilden pump

Wilden pump lubricant before use and use of the process do not need to add any.Reassembled after the demolition, it is necessary to add the appropriate grease between the central axis and copper cuff mounted diaphragm pressure plate can also be outside the platen inside of the coat of grease, so that both good positioning and easy sealing and demolition.
Demolition of the main valve spool valve sleeve must not contact with the hard and spool valve sleeve, the sophisticated spool valve Suite tie.
Loaded valve and pilot valve also need to add a small amount of grease to ensure good lubrication.
Before the valve is set into the valve housing coated with a small amount of grease on the outer O-ring in the valve housing, then unarmed pressure inside the can, do not beat.
Mounted pneumatic diaphragm pumps should the inside all accessories (intake part) Wash Sassafras dry, check all the seals are good seal (mainly refers to the axis of the U-shaped ring; thimble O-ring; guided check the O-rings ; diaphragm platen compaction seal inside and outside; the inner and outer cavity compaction seal; valve seal of the ball seat; pilot valve, air intake cover, the valve gasket seal), can also be side check edge grease side installation.
Note, pneumatic diaphragm valve gasket is positive and negative, can not pad wrong; want to confirm on the pilot valve in place to tighten the bolts, otherwise it will damage the thimble; 4 bolts on the valve, with particular attention to the principle of balance, and can not betoo tight, otherwise it will damage the valve housing.
