Pump bearing can be effected by what reason

  1. 图片1The effect of vibration on centrifugal multistage water pump bearing

    In ordinary use, vibration is quite sensitive to centrifugal multistage water pump bearing damage, spalling, indentation, corrosion, crack, wear and so on will be reflected in the bearing vibration measurement.Therefore, the size of vibration can be measured by using a special bearing vibration meter (frequency analyzer, etc.), and the specific situation of abnormal cannot be inferred from the frequency of centrifugal multistage water pump.The measured value varies with the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine before determining the judgment standard.

 

 

二、The effect of temperature on centrifugal multistage water pump bearing

High temperature is often used to indicate that the bearing has been in abnormal condition.High temperatures are also harmful to bearing lubricants.Sometimes bearing overheating can be attributed to the bearing lubricant.If the bearing in excess of 125 ° C for a long period of continuous transfer to reduce the bearing life.Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants.Contains impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seal, etc.

It is easy for the temperature to rise in the process of using the bearing.When the bearing temperature rises, first judge whether there is a misoperation. If the bearing temperature does rise, it should be handled as follows:

1. Check whether the centrifugal multistage water pump water pressure, water flow and pipeline system are normal.If the water is low, the filter may be blocked and cannot be treated in time, the filter can be shut down for treatment. When it is confirmed that it can work, it can be put into use again.

2. Check the oil pressure of the governor. If the oil pressure is low, it may cause the cooling water hydraulic valve to close.

3. Check whether the centrifugal multistage water pump bearing has abnormal sound, and detect whether the bearing pendulum is abnormal.

4. Take oil samples to observe whether there is any change in oil color, and test them to see whether they are deteriorated.If the deterioration is confirmed, the machine should be shut down and replaced with new oil.

5. Check whether the oil level is normal. If not, check whether the oil drain valve of the oil groove is closed and tight.If it has been shut down, oil should be added. If it is a sealant pad, oil should be stopped for processing.

Vibration on the bearing damage can be said to be quite sensitive, spalling, indentation, corrosion, crack, wear and so on will be reflected in the bearing vibration measurement.Therefore, the size of vibration can be measured by using a special bearing vibration meter (frequency analyzer, etc.), and the specific situation of abnormal cannot be inferred from the frequency.The measured value varies with the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine before determining the judgment standard.

We then look at the impact of temperature on the bearing, with high temperature often indicated that the bearing has been in an abnormal situation.High temperatures are also harmful to bearing lubricants.Sometimes bearing overheating can be attributed to the bearing lubricant.If the temperature exceeds 125℃ for a long time, the bearing life will be reduced.Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants.Contains impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seal, etc.

Therefore, continuous monitoring of bearing temperature is necessary, whether measuring the bearing itself or other important parts.If the operating conditions are unchanged, any change in temperature may indicate a failure.

Periodic measurements of bearing temperatures can be made using thermometers, such as digital thermometers, which measure the bearing temperature accurately and display it in units of ℃ or Fahrenheit.The importance of bearings means that when they are damaged, the equipment will be shut down, so this type of bearing is the best for centrifugal multistage water pump .
