Symptoms
the reason
Approach
Motor can not be started
â‘ no power supply
â‘¡ power one phase or two phase power
â‘ Check the power supply situation
â‘¡ Check the fuse contact point is good
Do not drain or drain enough
â‘ Suction tube blocked or suction line valve is not open
â‘¡ suction pipe is too long, sharp turn too much
â‘¢ suction pipe leakage
â‘£ Suction valve or discharge valve sealing surface damage
⑤ diaphragm pump residual air
â‘¥ fill valve group or diaphragm cavity leaks, oil spills
⑦ safety valve , compensation valve does not operate properly
⑧ plunger packing leaks seriously
⑨ motor speed is not enough or unstable
â‘© suction liquid level is too low
â‘ Check suction tube and filter, open the valve
â‘¡ bold suction pipe to reduce sharp turn
â‘¢ will leak parts sealed
â‘£ check the valve seal, if necessary, replace the valve
⑤ re-filling oil, exhaust air
â‘¥ identify leaks and eliminate parts
⑦ readjustment
⑧ adjust the packing gland or update the packing
⑨ stable motor speed
â‘© adjust the level of inhalation liquid
Pump pressure can not reach the performance parameters
â‘ inhalation, discharge valve damage
â‘¡ plunger packing leaks seriously
â‘¢ diaphragm or discharge pipe joints lax
â‘ update the valve
â‘¡ adjust the packing gland or replace the new packing
â‘¢ find the location of air leaks and eliminate
Reduced measurement accuracy
â‘ And "no drainage or lack of drainage" in â‘£ ~ â‘© the same
â‘¡ plunger zero offset
â‘ and "no drainage or lack of drainage" â‘£ ~ â‘© the same
â‘¡ readjust the plunger zero
Parts overheated
â‘ transmission tank too much or insufficient fuel, oil impurities
â‘¡ poor lubrication of the Deputy Sports
â‘¢ packing pressed too tight
â‘ replace the new oil, and the amount of oil
â‘¡ check and clean the hole
â‘¢ adjust the packing gland
Impact sound inside the pump
â‘ serious wear and tear of sports teams
â‘¡ valve lift is too high
â‘ adjust or replace parts
â‘¡ adjust the height of the lift to avoid valve lag
