Anhui Wanfulong  valve is widely used in chemical industry, rare earth, pesticides, petroleum, electroplating, metallurgy, electronics and other fields, every year large quantities of products to replace imports, selling the 30 provinces and autonomous regions and exported to Southeast Asia, Europe and other countries and regions.

 

Cause Solution

Play no liquid

1. Inside air intake pipe 2. 3. suction pipe leak inside the liquid pump hypoperfusion

 

4. The suction line clogged with debris 5. 6. pump reverse pumping height is too high

 

1. refilled or emptied of liquid gas 2. Check the suction pipe 3. The liquid refill

 

4. Clear the blockage 5. Adjust the steering 6. Lower mounting height

 

1. insufficient flow impeller speed is not enough damage within 2. 3. pipeline debris clogging impeller 1. 2. Check the motor and replace the power supply line 3. Clear blockage

1. The power is too large proportion of the transmission medium is too large and the motor axis 2. The axis error is too large pump 3. 1. mechanical friction reducing the viscosity or increase perfusion pressure readjust 2. 3. Check where wear and tear, repair

1. The lack of transport within the medium lift air impeller damage 2. 3. 4. delivery speed is not enough proportion of the medium is too large

1. refilled or emptied of liquid gas 2. Replace the impeller 3. Check the motor and power lines

 

4. Reduce the viscosity or increase perfusion pressure

 

Axis vibration motor pump error pump axis 1. 2. excessive height of the suction generated cavitation mechanical friction 3. 1. 2. readjust where reduced installation height 3. Check the wear and tear, repair

Shaft seal leakage and leakage

1. shaft snap ring gap is too large, the snap ring 2. Suction height is too loose, resulting in cavitation

 

3. The mechanical seal dynamic static ring wear, small spring pressure 4. Mechanical seal dynamic static ring fit well

 

1. Adjust the snap ring screws reduce installation height 3. 2. Replace worn materials, adjusting spring

 

4. Adjust the static ring
