GDL vertical multistage pipeline centrifugal pump maintenance

GDL vertical multistage pipeline centrifugal pump is good pump type in abroad on the basis of combining the use of user requirements and fire related standards, and according to JB/TQ6435 - 92 standard design and manufacture of a new generation of products, coat with 1 cr18ni9ti stainless steel, the quality of the shaft sealing with wear-resistant mechanical seal, pump suction and discharge pipe in the same line. By of rotor shaft, impeller, the impeller block set, shaft sleeve and other parts, water, middle, water paragraphs with tighten bolt connection. Shaft sealing adopts mechanical seal, with the balance chamber pressure lubrication and cooling water. Is the major industry of hot and cold water or liquids such as physical and chemical properties similar to water is the best pump for the transmission.

GDL type vertical multistage pipeline centrifugal pump maintenance:

type GDL vertical multistage pipeline centrifugal pump running preventive maintenance and

1, the inlet pipe road must be sealed, can't water and air;

2, ban GDL multistage pipeline pump cavitation condition in the long run;

3, ban GDL multistage pipeline pump running in the big traffic conditions, the motor current long running;

4, regularly check the pump running motor current value, try to make the pump in design conditions within the scope of operation;

5, GDL multistage pipeline pump should be modes in the running, so as to avoid accidents;

6, GDL multistage pipeline water pump for every 500 hours running for bearing oil;

7, GDL multistage pipeline pump after running for a long time, due to mechanical wear, increase the noise and vibration of generating unit, should stop check, can change into the necessary quick-wear part and bearing, the outage period is usually one year.

type GDL vertical multistage pipeline centrifugal pump mechanical seal maintenance

1, the mechanical seal lubricants should be clean without solid particles;

2, it is strictly prohibited to mechanical seal under the condition of dry grinding work;

3, should be set before starting dynamic multistage pump pipe ( Motor) Sudden starting in several times, in order to avoid damage the mechanical seal is broken.
