Causes of water ingress in gear pumps and preventive measures

Publish: Browse:
In the daily use of gear pumps, water often appears in the pump body. No problems can be found when inspecting the pipelines and pumps, and some people come back and ask if our pumps have such problems In fact, there is no problem with the pump itself. Today we have summarized the following reasons for your reference:
First, the reason for water ingress
1. The water tank is condensed due to the alternation of cold and heat on the fuel tank cap, and drops of water fall into the oil.
2. The water-cooled cooler in the transmission pipeline leaked into the oil due to seal damage or cooling pipe rupture.
3. Moisture, rain water, human sweat, water cooling liquid splash (such as grinder) in the oil barrel leaked into the oil.
Measures to prevent moisture from entering and rusting
1. The transportation and storage of oil products must be protected from rainwater. Oil drums filled with hydraulic oil must not be placed in the open air. The rubber seal of the oil drum cover must be reliable. The oil container should be placed in a dry and sheltered place.
2. Water leakage and water leakage of water-cooled oil cooler must be checked and eliminated frequently. When this failure occurs, the oil is white and turbid. At this time, check the seal for damage and the cooling water pipe for damage, disassembly, repair or replacement.
3. Indoor equipment should prevent house leaks and rain water from flowing in through windows. Oil change of outdoor equipment (such as walking machinery) must be performed on sunny days. Gear pumps must be used to avoid rainy days. The fuel tank must be tightly sealed to prevent rainwater from leaking into the oil
4. Use oil with good oil-water separation performance. There are oil filters in foreign countries that can filter the water in the oil. It is better to install it.
5. For light-load equipment under normal conditions, the moisture content should not be greater than 0. 2%; equipment and precision equipment with long intermittent time, the mixed water should be less than O. 05%.
