Wilden pump demolition and re-assembly guide
5/7/2012 7:23:58 PMWilden pump demolition and re-assembly guide:
Warning: repair wilden pump, need to first air source piping removal of wilden pump, and air pressure in wilden pump discharged. Removal of all connections the import and export of wilden pump, pipelines, and pump the fluid discharged into a suitable container. A protective cap, glasses, gloves.
First.Wilden pump action or operation is very slow:
(a) check the air inlet side of the filter or air filter impurities.(b) Check the air valve is stuck with cleaning fluid to clean the air valve.
(c) check whether the air valve wear, if necessary, replacement of the parts.
(d) The seal parts of the body status of the examination center, if badly worn, you can not achieve the sealing effect, and the air will drain from the air outlet side. Due to its special structure, only use GLYD ring.
(e) check the air valve piston is normal.
Second.Wilden pump severe vibration
May be electric rotor imbalance, or poor coupling combination, curved bearing wear; rotate some of the parts may also be loose, broken; perhaps piping bracket firm. Can be taken to adjust, repair, reinforcement, replacement and other ways to deal with.
Third. Wilden pump pipeline leaks or leak
May be installed nut screw failed to exercise stringent. If the leakage is not serious, in place of the leak or leaks smearing cement or asphalt oil mixing grout. Temporary repairs can be coated with wet mud or soft soap. If leaks in the joints, you can hand tighten the nut. Severe water must be re-disassembly.
Mostly due to packing too tight, cooling water into the less packing or shaft surface damage. The fillers can be taken to relax the appropriate measures to clean up a sealed tube blockage. Packing wear and tear must be replaced with new. Soaked in the oil before installation, load-by-turn, the incision should be staggered, so that can reduce the leakage. Last lap filler installed, to install the gland operation to adjust the tightness.
Fourth.Wilden pump do not absorb water or undrained
Causes of death for the end of the valve card, the treatment part of the blockage, suction height is too high or absorbent leak may also be due to the steering does not, the impeller is not clogged. Were taken one by one to check the bottom valve repair, and clear the blockage and corrective steering, cleaning the impeller and other measures to deal with.
