1 Subject content and scope of application
HG2263-92
1.1 This standard specifies the type and basic parameters of the YLJ single-stage cantilever double-acting liquid ring chlorine pump (hereinafter referred to as liquid ring pump). 1.2 This standard is applicable to liquid ring pumps for chlorine with a purity of not less than 90%, a water content of not more than 0.6%, and an inlet temperature of not more than 40°C. The circulating liquid is 98% concentrated sulfuric acid with a pump temperature of not more than 30°C. 2. Reference standards
HG2101 Single-stage cantilever double-acting liquid ring chlorine pump test and parameter measurement method 3 Liquid ring pump performance requirements and performance range 3.1. Performance requirements
The performance parameter values ​​of liquid ring pumps are greatly affected by the medium and other working conditions. The performance parameters measured during production and testing must be converted to the same benchmark, which is the specified conditions for the performance of the liquid ring pump. 3.1.1 Medium conditions
Air is the specified gas medium, and clean water is the specified circulating liquid. 3.1.2 Inlet conditions
a. Inlet pressure
0.101MPa (absolute pressure);
b. Inlet temperature
c. Relative humidity
3.1.3 Inlet water temperature
3.1.4 The speed should comply with the provisions of Table 1,
3.2 Performance range
Rated gas volume 150~750m/h;
Rated pressure 0.15MPa.
4 Type
4.1 The liquid ring pump is a cantilever diameter Double-acting structure for air intake and exhaust. 4.2 The liquid ring pump is connected to the drive motor through an elastic coupling. 4.3 From the pump end, the impeller rotates counterclockwise. 5 Mark
5.1 YLJ: indicates the type code of the liquid ring pump. Approved by the Ministry of Chemical Industry of the People's Republic of China on January 8, 1992. 10
