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 |
