Why is the hydraulic oil pump not oiled

Why hydraulic oil pumps don't have oil: Cause analysis and solutions

Hydraulic oil pump is a core component in the hydraulic system, and its normal operation directly affects the operating efficiency of the entire system. Recently, many users have reported that the hydraulic oil pump has not been oiled, which has caused the equipment to not operate normally. This article will analyze the reasons why hydraulic oil pumps are not oiled and provide solutions based on the hot topics and hot contents of the entire network for the past 10 days.

1. Common reasons why hydraulic oil pumps do not have oil

According to recent user feedback and industry experts' analysis, the reasons why hydraulic oil pumps are not oiled are mainly concentrated in the following aspects:

2. Analysis of specific causes and solutions

1. Oil problem

Oil problems are the most common cause of hydraulic oil pumps not being oiled. Too high oil viscosity can lead to difficulty in pumping oil, and too low viscosity can lead to increased internal leakage. In addition, oil contamination or insufficient liquid can directly affect the normal operation of the pump.

Solution:

• Check whether the oil viscosity meets the pump's usage requirements.
• Change the oil regularly to avoid contamination.
• Make sure the oil level of the tank is within the normal range.

2. Pump body failure

Wearing inside the pump body or damage to the seal will cause the pump to lose oil suction capacity. If the bearing is stuck, it may cause the pump to be completely inoperable.

Solution:

• Regularly check the internal wear of the pump and replace the worn parts in time.
• Replace damaged seals.
• Check the bearing status and replace it if necessary.

3. Oil suction pipeline problem

A blockage or leak in the oil suction pipeline will directly affect the oil suction effect of the pump. Excessive oil suction height may also cause the pump to not absorb oil normally.

Solution:

• Check whether the oil suction pipeline is unobstructed and clean up blockages.
• Check whether the pipe connection is leaking, tighten or replace the seal.
• Ensure that the oil suction height is within the design range of the pump.

4. System design issues

Improper pump selection or unreasonable fuel tank design may cause the pump to fail to meet system requirements.

Solution:

• Re-evaluate the pump selection to ensure that its parameters meet system requirements.
• Optimize the fuel tank design to ensure sufficient oil supply.

5. Other reasons

Motor reversal or filter clogging may also cause the pump to not be oiled.

Solution:

• Check that the motor is steering correctly.
• Clean or replace clogged filters.

3. Preventive measures

In order to avoid the problem of the hydraulic oil pump not being oiled, users can take the following precautions:

4. Summary

The lack of oil on hydraulic oil pumps is a common but complex problem and can be caused by a variety of reasons. Through the analysis and solutions of this article, users can quickly locate problems and take corresponding measures. Regular maintenance and specification of operations are key to avoiding such problems.

If you encounter the problem that the hydraulic oil pump is not oiled, it is recommended to follow the above steps to check one by one, and contact professional maintenance personnel to deal with it if necessary.
