DSJH Petrochemical Process Pump

DSJH Petrochemical Process Pump

Details

Overview:

GSJH Petrochemical Process used for oil refining, petrochemical and chemical industries and other transporting petroleum and its products, which fully complies with the American Petroleum Institute AP1610 standards. GSJH Petrochemical Process Pump with high reliability, long life, high generalization and high efficiency.

Performance Range:

Flow value Q = 7.5 ~280m3. / h

Head H= 80 ~330m

temperature t = -45 ~ +450℃(-196℃can be reached if special requirement)

Model Specification:

Example: GSJH1 1/2*3*10 1/2 L-D

GSJH: double-stage single-suction end-supporting process pump

1 1/2: diameter of output port (inch)

3:diameter of intake port(inch)

10 1/2: max diameter of impeller(inch)

L: number of impeller

D: cutting times of impeller, means the forth cutting.

Structure Features:

GSJH pump is two-stage suction point supporting centrifugal process pump, by the radial split of casing structure, it is especially suitable for high temperature and pressure as well as transportation of flammable or toxic liquid. In order to decrease the displacement caused by heat-expansion cold-contraction. Pumps with outlet diameter 4 inches and 4 inches above ,then it would be designed dual vortex chamber to balance the radial force pump. All the transition from first stage output to second stage suction flow uses inner channel overall casting, and two-way symmetric distribution.

Liquid flow through a pressure pump can exhaust themselves, but the upper and lower pump volute are left umbilical son, when the user needs to put the exhaust and fluid, you can open ZG3 / 4 screw holes at the job site with the API plugs screw on.


[GSJH Petrochemical Process Pump works]: gear pump failure and possible solutions: 1, the internal gear pump wear parts. 2, the pump casing wear 3, wear the gear pump seal, rubber seals of aging. 4, less than the amount of oil pump oil or no oil pressure. The model described above does not mean that the pump works, please understand. For more information, please visit Xi shield Pump Home view. Thank you! [GSJH Petrochemical Process Pump Selection (model)]: runtime does not flow metering pump which causes and solutions: 1, suction side piping valves closed or blocked pipes. Open pipe valve, do not clear when work. 2, the inlet pressure is too low. Metering pump installation height adjustment can be solved. 3, one-way valve damage. The need for repair or replacement of metering pump supporting one-way valve. Metering pump to reduce the measurement accuracy of the reasons for which, how to solve? 1, the metering pump pump speed too fast, relatively large impact on the pipeline so. Metering pump to adjust pump speed. 2, one-way valve sealing performance. Replace seals or replace check valve. 3, the metering pump speed instability, faster or slower. Identify the causes and stable pump speed. Model Description: GSJH4 × 6 × 14H-AGSJH-two single-suction centrifugal process pump bearing ends 4-- pump outlet diameter (inches) 6 - the pump suction diameter (inches) 14 - impeller diameter (inches) Code H-type impeller impeller cutting the number of A-to A, B, C ... that
