How to Tell Oil Pump or Leaky Bearings?

In the use of construction machinery, understanding and timely judgment of oil pumps and bearings whether oil leakage is to ensure the normal operation of the equipment is the key. This article will introduce how to identify the oil pump and bearing oil leakage, in order to protect the stability and reliability of machinery.

 

How to tell if oil pump is leaking

1.Observe whether there are oil stains around the oil pump

One obvious sign of oil pump leakage is to find oil stains near the oil pump. Carefully check the surface of the oil pump and the surrounding area, if you find oil stains, it is likely that the oil pump has a leakage problem, which needs to be promptly investigated to prevent it from affecting other diesel engine parts.

 

2.Check the sealing parts of the oil pump

A diesel oil pump usually contains several sealing parts, such as shaft seals and joint seals. Check these seals for damage or deterioration to ensure they are working properly. Broken seals can lead to oil leakage from the pump.

 

3.Check the bottom of the pump

The bottom of the pump is another common leakage point. Check for oil stains on the bottom connections, especially after the machine has stopped, as this is when signs of leakage may be more noticeable.

 

4.Pay attention to the oil pressure gauge

An abnormal oil pressure gauge can be an indication of an oil pump leak. If the oil pressure gauge shows unstable pressure or a sudden drop in normal operation, then there may be a leak in the oil pump.

 

5.Listen to the sound of the oil pump

The oil pump should be smooth and quiet during normal operation. If you hear unusual noises, especially with squeaking or fluid surging, it may be a sign that the pump is leaking.

 

How to determine bearing leakage

1.Check for oil around the bearings

Similar to an oil pump, checking for oil around the bearings is the most intuitive way to tell. Bearing leaks can cause lubricant to build up at the bearing and form oil stains.

 

2.Check bearing seals

Bearings usually have seals to prevent lubricant leakage. Check to see if these seals are in good condition. If they are found to be broken or deteriorated, it may lead to oil leakage from the bearing.

 

3.Observe the appearance of the bearing

Check the appearance of the bearing for foreign objects or damage. Foreign objects may damage the seals and cause oil leakage. Also, damaged bearings may cause oil leakage problems.

 

4.Check the bottom of the bearing

The bottom of the bearing is also a common area for oil leakage. Carefully inspect the bearing joints for oil stains, especially after the equipment has stopped, and carefully maintain each component to prevent it from affecting the normal use of other equipment components such as the starter motor and alternator.

 

5.Judging by bearing temperature

Abnormally high bearing temperatures may be a sign of oil leakage. Use an infrared thermometer or other temperature checking tool to monitor whether the bearing temperature exceeds the normal range.

 

Regularly checking the oil pump and bearings for oil leaks is vital to the normal operation of construction machinery. By observing oil traces, checking sealing components, paying attention to oil pressure gauges, listening to sounds and meticulously inspecting bearings, you can effectively determine the exact cause of oil leaks. Regular maintenance and servicing will prolong the life of the equipment and ensure that construction machinery can run efficiently under various working conditions.
