Petrochemical pumps refer to pumps used in petrochemical industry. Because almost all the transporting liquid is flammable, and most of the temperature and pressure conditions are harsh, higher or highest level pumps are required.
Requirements for petrochemical pumps in petrochemical plants
a. For petrochemical pumps that transport flammable, explosive, toxic or precious media, shaft seals must be reliable or non-leak pumps such as canned motor pumps, magnetic drive pumps, pneumatic diaphragm pumps, etc.
b. For petrochemical pumps that transport corrosive media, it is required to use corrosion-resistant materials for the flow parts.
c. For petrochemical pumps transporting solid particulate media, it is required that the flow-through parts be made of wear-resistant materials, and if necessary, the shaft seals should be washed with clean liquid.
Must meet site installation requirements
a. For petrochemical pumps installed in the presence of corrosive gases, measures to prevent atmospheric corrosion are required.
b. For petrochemical pumps installed at an outdoor ambient temperature below 20 ° C, it is required to consider the cold brittleness of the pump and use low temperature resistant materials.
c. For petrochemical pumps installed in explosion areas, explosion-proof motors shall be used according to the explosion area grade.
d. For factories that require major maintenance once a year, the continuous operating cycle of the pump should generally not be less than 8000h. In order to meet the requirements of a three-year overhaul, API 610 (10th edition) stipulates that the continuous operation cycle of pumps for the petroleum, petrochemical and natural gas industries is at least 3 years.
e. The design life of petrochemical pumps is generally at least 10 years. API 610 (10th edition) stipulates that the design life of centrifugal pumps for the petroleum, petrochemical and natural gas industries is at least 20 years.
f. The design, manufacture and inspection of petrochemical pumps shall comply with the relevant standards and specifications.
g. The pump factory should guarantee the performance of the pump within the range of the power supply voltage and frequency. China's power supply voltage and frequency change range is: voltage 380V ± 10%, 6000V ± 10%; frequency 50Hz ± 1Hz.
