GB/T 14794-2002 in English

《GB/T 14794-2002蒸汽往复泵》由TC211（全国泵标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了一般蒸汽往复泵、蒸汽往复热油泵的型式与基本参数、技术要求、试验方法和检验规则、标志、包装与贮存。本标准适用于输送温度不高于110℃、运动黏度不超过850mm2/s的清水和石油化学性质类似的其他液体的一般蒸汽往复泵。本标准适用于输送温度不高于400℃的石油制品的蒸汽往复热油泵。输送温度不低于-40℃的液化气泵可参照使用本标准。

Scope

This standard specifies the type and basic parameters, technical requirements, test methods and inspection rules, signs, packaging and storage of general steam reciprocating pumps and steam reciprocating thermal oil pumps. This standard applies to general steam reciprocating pumps for conveying clean water with a temperature not higher than 110°C and a kinematic viscosity not exceeding 850 mm2/s and other liquids with similar petrochemical properties. This standard is applicable to steam reciprocating thermal oil pumps for conveying petroleum products whose temperature is not higher than 40°C. The liquefied gas pump whose delivery temperature is not lower than -40U can refer to this standard. Note: The abbreviation "pump" in the text of this standard refers to the joint abbreviation of general steam reciprocating pump, steam reciprocating thermal oil pump and liquefied gas pump.
