CBN series heavy oil pump gear oil transfer pump electric motor connection 380v 220v 415v
1.Introduction
CBN series heavy oil pump composes of pump body, cover ,gear, and shaft-end seal parts and so on. Using transmission of bridge type exterior pulley and direct connection of motors with low speed and noise, high suction characters. On the other hand, sealing using 2 types mechanical sealing structures due to the transfer liquids.
The series can all adopt stainless anti-acid and anti-corrosion material to make, suitable for food industry,pharmacy and daily chemical industry.
Proper medium temperature:below 230C
Proper medium viscosity:below 2000mm2/S
2.Transfer medium
1).Paint,rosin,paraffin wax,soap,sludge,asphalt,high viscosity oil, etc.
2).Butter,syrup,sauce,grease,toothpaste,etc.

Troubles and Solutions
Troubles | Productive Reason |
Solutions |
Discharging oil or discharging little oil | 1.Revolving direction reversed | 1.Change in to right direction 2.Open valve |
No pressure or pressure not rising | 1.The button of the pressure meter is still in OFF position 2.The pressure of the safety valve is too low3.Side tube valve is on 4.High temperature,low viscosity o foil and small resistance of the tube 5.Air leakage in the tube | 1.Press the button ON of the pressure meter2.Readjust the safety valve pressure 3.Close the side tube valve 4.Reduce oil temperature 5. Check out absorption tube |
Oil leakage in mechanical seal | 1.Shaft seal has not been adjusted properly 2.O-seal ring wear 3.The defects caused by wearing of stationary and rotating rings of mechanical seal4.Spring flabby | 1.Adjust it 2.Change O-seal 3.Change stationary and rotating rings or polish the magain4.Change spring |
Noise and vibration | 1.Improper assembling 2.The in concentricity of pump shaft and motor shaft 3.Absorption tube or filter stopped up 4.Absorption tube dimension is too small and long.It could not pump in,for resistance is too big 5.Oil exhaustion tube’s resistance is too big6.Air leakage 7.Fastener is relaxed 8.Gears and bearings stand sides show serious wear and tear or gripped | 1.Check out and maintain 2.adjust it 3.Clear dirt things in the absorption tube or filter 4.Read just it 5.Check up whether exhaustion tube or valve are stopped up6.Check up and maintain7.Check up and tighten it 8.Disassemble and maintain or change them |
Safely valve unworkable | 1.Wrong position2.Pressure too high 3.Safety valve chip gripped | 1.Reassembling it2.Lower the pressure 3.Disassembling,wash and adjust |
