Booster pump installation, GDL vertical multistage high-pressure booster pump installation and maintenance

GDL multistage high-pressure pump used in the installation process need not regular maintenance and maintenance, if not done in accordance with its operating mode, is likely to appear all sorts of problem, in order to guarantee the normal operation of the high pressure booster pumps, not because a small problem caused big failure, the user needs regular maintenance, to prevent the generation of pump failure.

type GDL vertical multistage high-pressure pump installation instructions:

1, line weight, no, no, when installation should bear on the pump, or vulnerable ring pumps;

2, the structure of the pump and motor as a whole, the factory has correction by manufacturer, so no adjustment when installation, so when installation is very convenient.

3, before the installation of GDL type high pressure booster pump should be carefully check the pump flow with or without affecting the operation of the pump hard, ( Such as stones, iron ore, etc. ) In order to avoid the pump run time loss and flow components;

4, installation must tighten the anchor bolts, the fact and each interval time line to pump inspection to prevent the loose, lest they occur when the pump starts violent vibration and impact performance;

5, for the sake of convenient maintenance and use of safety, in the import and export pipeline installation a regulating valve of the pump and the pump to install a pressure gauge, near the import and export for high head, in order to prevent water hammer, should also be to install a check valve in front of the exit gate valve power to cope with sudden loss of power, such as accident, to ensure the pump running under the optimum condition, increase service life of the pump;

6, pump used for suction capacity, should be equipped with a bottom valve, and import pipeline should not have too many corners, at the same time can not have water leakage, leakage phenomenon, so as not to affect the pump inhalation can;

7, to not make the impurities into the pump and plug flow impact performance, filters should be installed in front of the pump inlet;

8, installation of pipe before rotating pump rotor parts, should be no friction or jammed phenomenon, otherwise the pump should be disassemble to reason.

type GDL vertical multistage high-pressure pump start-up and shutdown:

before starting to prepare

1, with the hand turn coupling, the impeller should be no card grinding phenomenon, flexible rotation;

2, open the inlet valve and open the vent valve to make liquid fills the water pump cavity, then close vent mouth;

3, such as conveying hot liquid, should be preheated before starting, speed of 50 ℃ / h, the preheating of the pump is made by conveying liquid cycle to achieve, so that each part is heated evenly;

4, should first hand disk dynamic GDL booster pump several times to make mechanical seal face lubrication water into;

5, inching motor, steering is correct.

starting and running

1, the full import valve, closing out pipe gate;

2 and, turning on the power supply when the pump at normal speed, gradually open the valves on the discharge pipe, and adjust to the required conditions;

3, observe the meter reading, check the shaft seal leakage, normal time mechanical seal leakage 3 / leakage points, check the motor, bearing temperature at 70 ℃ or less, if found abnormal situation, should be timely treatment. Parking

1, close out pipeline valve gradually; 2, close the import valve;

3, such as environmental temperature is below 0 ℃. Should put all the liquid in the pump to avoid frost crack water pump;

4, such as stopping for a long time, pump should be disassembled to clean and packaging.

GDL multistage high-pressure pump repair and maintenance:

run in the preventive maintenance and

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

2, prohibition of GDL type high pressure booster pump cavitation condition in the long run;

3, prohibition of GDL type high pressure booster pump in the big traffic operation, 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 vertical pump should be in the running modes, so as to avoid accidents;

6, GDL vertical booster pump for every 500 hours running for bearing oil;

7, GDL vertical booster pump after a long run, 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.

the 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 GDL booster pump ( Motor) Sudden starting in several times, in order to avoid damage the mechanical seal is broken.
