Maintenance of pump pneumatic valve after stalling should pay attention to matters

we it is necessary to analyze the main reason for the downtime, so you can avoid unnecessary machine after damage. Downtime is mainly caused by the failure of mechanical seal. Failure of performance are mostly leakage, leakage reason has the following kinds: (1) message ring sealing surface leakage, the reason mainly has: face flatness, coarse degree not meet the requirements, or surface scratch; End face between particulate matter, two end can't also run; Installation does not reach the designated position, not accurate. Briefly pneumatic valve pump maintenance should pay attention to matters after stalling gear pump belongs to quality in all of the gear pump somewhat nice and have some special application scope. But stainless steel pump at work will flush some unexpected failure, such as downtime. We it is necessary to analyze the main reason for the downtime, so you can avoid unnecessary machine after damage. Our main products are: pneumatic pneumatic valves, pneumatic ball valves, pneumatic butterfly valve, pneumatic actuators, http://www. /。 Downtime is mainly caused by the failure of mechanical seal.

Failure of performance are mostly leakage, leakage reason has the following kinds: (1) message ring sealing surface leakage, the reason mainly has: face flatness, coarse degree not meet the requirements, or surface scratch; End face between particulate matter, two end can't also run; Installation does not reach the designated position, not accurate. (2) compensation ring seal leak, the reason mainly has: gland deformation, no pretightening average; Installation is not accurate; Sealing ring is not in conformity with the quality scale; Seal selection divergence errors.

Special note: all comments do not represent the home station article reprinted on view, such as the need of related products, please contact the site, all peer originator. (2) heat pump parking should be in accordance with the equipment technical documents defined, should be every min partial plate after parking car half a circle, until the pump body temperature drop to ℃. (3) when parking the cryogenic pump, when no special requirements, the pump should always be full of liquid; Suction pneumatic valve and discharge valve should be kept normally open state; Adopt double mechanical seal of pump in low temperature, liquid level controller and sealing liquid pump seal cavity pump grouting pressure shall be maintained. Pneumatic pneumatic valve co. , LTD. (4) centrifugal oil pump stop running should be closed after the population of the pneumatic valve, pump to pump closed in turn attached again after cooling system of pneumatic valve. Discharge pump inside the backlog of liquid, prevent rust and frost crack. Pneumatic complete sets of pneumatic valve co. , LTD. , http://www. /。
