Corrosion resistant chemical centrifugal pump primary, secondary, tertiary maintenance method

Corrosion resistant chemical centrifugal pump is most used in the field of chemical centrifugal pump, in the process of the operation of the pump, there are a lot of influence the efficiency of the corrosion resistant chemical pump operation, and the corrosion resistant chemical pump maintenance is relation with using lifespan is very direct, so to strengthen the daily maintenance and maintenance of chemical pump is necessary.

a level, corrosion-resistant chemical centrifugal pump maintenance:

1) Chemical centrifugal pump in the water, it must be a good seal performance, so as to avoid leakage or leakage problems. In addition, the pump is not in the condition of cavitation work for a long time, because it is a big damage for pump.

      ( 2) Flow if the pump is running state, then for the motor, is no long-term super current operation.

      ( 3) For chemical centrifugal pump operation process, should have personal guard, so that once appear problem, can be processed in a timely manner to solve.

      ( 4) When chemical centrifugal pump run full after a certain time, for the bearing lubrication and maintenance, to ensure that its service life.

2, corrosion-resistant chemical centrifugal pump secondary maintenance:

for secondary pump maintenance, shall be carried out on the basis of the level of maintenance, so the work content is increased, the specific is as follows:

1) For chemical centrifugal pump mechanical seal lubrication, the main requirements, is for lubricating oil etc. Should be no solid particles.

      ( 2) When the long run, is likely to get bigger noise, then stop the engine should be, there is damage to the parts, to timely replacement.

3, corrosion-resistant chemical centrifugal pump of daily maintenance and maintenance:

1, the unit using chemical centrifugal pump equipment lubrication in strict accordance with the provisions of the proper use of oil.

2, equipment lubricating oil standard

1) Oil bath lubrication oil level should be kept in sight glass window 1/2 ~ 2/3 or the provisions of the gauge calibration.

      ( 2) Cycle, such as concentrated lubrication oil level should be kept in the calibration procedures regulations.

      ( 3) Grease lubrication

n > 3000 r/min, the fatliquoring quantity for a third of the bearing box volume;

n 3000 r/min or less, fatliquoring amount for 1/2 of the bearing box volume.

3, keep the equipment clean, dry, no oil, no leakage.

4, check the running status of centrifugal pump every day to deal with in time when problems found.

      ( 1) Daily check the centrifugal oil pump suspension indoor oil level is appropriate, must be kept in oil mark 1/2 and 2/3.

      ( 2) Check for leaks shaft seal and the jointing sealing surface;

      ( 3) Check the cooling system, sealed lubrication system was clear, pressure, temperature is in the reasonable scope;

      ( 4) Check whether there is running stability, vibration;

      ( 5) Check whether couplings, safety mask, frame bolts loose;

      ( 6) Check the bearing temperature, the highest temperature should not exceed 70 ℃ ~ 75 ℃ in general.

5, weekly check bearing box lubricating oil or grease oil level;

6, monthly check vibration condition, and judge the bearing wear, it is forbidden to centrifugal pump in time to work, because of the centrifugal pump in time not only work under the condition of vibration, but also will affect the life of the water pump, therefore, be sure to pay special attention to.

7, are strictly forbidden in the centrifugal pump into the metal objects and acquire the flexible material such as rubber, cotton yarn, plastic sheeting, so as not to damage the pump flow components and blocking impeller passage, make the pump can't work normally.

8, the first month of the centrifugal pump is running, running after 100 h. After changing suspension oil lubricating oil, indoor centrifugal pump operating 500 h, each change of a lubricating oil.

9, stop for a long time should be no net system of material, the temperature is lower check antifreeze anti coagulation;

10 2000 h operation, centrifugal pump should be periodic inspection, repair or replace damaged parts, often make the centrifugal pump is in good condition.

after 11, the new installation and maintenance of centrifugal water pump, we must first try after good motor steering, and then put on the coupling of the dowel pin.

the above for corrosion resistant chemical centrifugal water pump maintenance content description, hope everyone after learning, can firmly grasp, and well applied to practice, to prolong the service life of pump. Moreover, this work is also very necessary, otherwise, will affect the use of its performance and using effect.
