Petrochemical pump type and significance

At present domestic manufacturer production of petrochemical pump mainly include: stainless steel flexible, dby electric diaphragm pump, pump HKZB sliding vane pump, IH stainless steel petrochemical pump, IHF fluorine plastic chemical pump, the FSB fluorine plastic petrochemical pump, CQB chemical magnetic pump, IMD, FZB chemical self-priming pump magnetic pump and so on. These petrochemical pump is widely used in chemical industry, metallurgy, pharmacy, to foil etc, all have important applications.

For example: IH50-32-160

IH - international standard single-stage single-suction chemical centrifugal pump

50 - suction diameter (mm)

32 - outlet diameter (mm)

160 - the name of the impeller diameter (mm)

Chemical pump needed to meet the requirements

(1) must satisfy the capacity and head, pressure, temperature, process parameters such as NPSH requirements.

(2) must meet the requirements of dielectric properties:

1 to carry flammable, explosive, toxic or valuable medium pump, require no leakage of pump shaft sealing is reliable or adopted, such as shielding pumps, magnetic drive pumps, diaphragm pumps, etc.

2 for the pump for the transmission of corrosive media, request flow components with corrosion resistant materials.

Three pairs of conveying pump containing solid medium, the required flow components adopt wear-resisting material, shaft seal should use clean liquid washing when necessary.

(3) must meet the requirements of on-site installation.

1 the use of pump installed in the presence of corrosive gas, atmospheric corrosion prevention measures.

Of installed in the outdoor environment temperature is lower than 2 ~ 20 ℃ below the pump, to consider pump cold short phenomenon, low temperature resistant materials.

3 for the pump installed in explosive area, should be based on regional level, and explosive use explosion-proof motor.

(4) for annual overhaul of the factory, the continuous operation of the pump cycle generally should not be less than 8000 hours. To adapt to the requirement of three years a major overhaul, APl (version 8) regulations 610 oil, heavy chemical and industrial gas pump cycle for at least 3 years in a row.

(5) of the pump design life is generally at least for 10 years. APl (version 8) regulations 610 oil, heavy chemical and industrial gas centrifugal pump design life of 20 years at least.

(6) of the pump design, fabrication, inspection should comply with the relevant standards, norms,.

(7) to determine the pump model and manufacturing plants, should be comprehensive consideration of pump performance, power consumption, reliability, price, and manufacturing specifications and other factors.
