Malfunction description |
Reason |
Solution |
Pump is working, but no fluid is discharged or low outlet pressure, few fluid is discharged. |
Due to serious damage of check valve(ball & seat), so that it is not able to seal properly |
Dismantle both upper and bottom seat, if a huge gap between ball and seat, ball can be changed, seat can be continued using flip. |
Main valve serious damage, air leakage |
Change spool valve & valve bush of main valve |
|
Fluid inlet or pipe are unsealed |
Checkif fluid inlet and pipe are sealed properly |
|
Exceed pump's performance |
Adjust installation position of pump, as closer to fluid as possible. 泵的安装位置越靠近流体越好 |
|
"O"ring of pilot valve damages |
Check pilot valve 检查导向阀 |
|
Damage of internal spring or " "O"" ring of quick adapter which is connected to the pump.进气快接头内的弹簧或 O 型 圈损坏 |
Dismantle quick adapter, check if it works after connect to the air source |
|
Unsealing due to loosen bolts 螺 栓松 |
Tightening all bolts 紧 固所有螺栓 |
|
Outlet is blocked |
Check outlet and valve opening |
|
Ball is not able to fully return by its own weight and seal due to high viscosity of fluid |
Change a heavier ball or stainless steel ball 更 |
|
Unsealing due to damage of " U" ring of shaft, " O" ring of thimble or gasket of pilot |
Check all rings, gaskets, change if damaged |
|
Fluid leaks out form muffler due to damage of diaphragm or washer. |
Change diaphragm, tightening washer |
|
Insufficient air pressure or air flow |
Increase air pressure or air flow |
|
Flow limit due to inflation of ball |
Check chemical compatibility of ball material and fluid 检查阀球与流体的化学适应性 |
|
Pump is not working |
Main valve is stuck, unmovable by hand serious damage of spool valve of main valve, huge gap causes air leakage |
Change spool valve & valve bush |
Pores of pilot valve are blocked, glyd ring of valve bush damages seriously, air leakage |
Clean up valve casing, change Spool assembly |
|
Valves of inlet and outlet stay shut |
Release valves |
|
Muffler is blocked, air suffocate |
Change muffler |
|
Damage of thimble sealing, thimble socket;bend of thimble and other issue |
Change thimble and socket |
|
Himble falls into mid chamber |
Change mid chamber |
|
Excessive lubrication |
Decrease lubricating oil volume in oil-water separator 降低油水分离器润滑油流量 |
|
Air leakage due to " U" ring of shaft damages seriously |
Change " U" ring |
|
Air valve stays shut |
Solenoid valve fails or air source is shut |
|
Mid chamber occurs pores due to corrosion |
Change mid chamber |
|
Air valve, pilot valve, air inlet gasket damage |
Change damaged parts |
|
Material solidified in cjamber |
Dismantle chamber and clean up |
|
Pump is working after outlet valve is shut |
Outlet valve is not totally sealed |
Shut outlet valve totally or change it |
Check valve(ball & seat) is not totally sealed, sundries might be stuck between |
Change check valve(ball & seat) of clean sundries |
|
After a period of time works normally, the pump fails to work, then it back to normal again after a few hours in winter time |
Pump is frozen |
Keep air sorce dry and moisture percentage of air source as less as possible. release water in air compressor, air container air pipes on time |
Change surrounding environment, keep warm in order to avoid freezing |
||
Slow down working frequency, so that avoid freezing 放慢工作频率,以免结冰 |
||
Add a few lubricating oil, lower the freezing point 加 入少量润滑油,降低冰点 |
||
Noise or abnormal sound |
Sound due to ball in the pump shell |
无需维修,不影响正常使用 |
Mid chamber occurs a loud noise when release air 中 间体排气时发出很大的声音 |
Change muffler |
|
Outlet occurs bubble |
Inlet or inlet pipes are not sealed properly |
Check if fluid inlet and pipe are sealed properly |
Air leakage due to damage of diaphragm or looseness of washer |
Change diaphragm, tightening washer |
|
Fluid leaks from chamber |
Leakage occurs around bolt |
Retightening bolt |
Leakage occurs around muffler |
Check diaphragm and washer |
