How to deal with abnormalities in the hydraulic system of a hydraulic press

During the daily use of a hydraulic press, abnormalities in the hydraulic system may cause hydraulic equipment failure or reduced work efficiency. Now, let's learn about how to deal with abnormalities in the hydraulic system of a hydraulic press.

The following content is sorted out and presented by hydraulic experts from Dongguan Jianlong Hydraulic Machinery Co., Ltd., a Chinese intelligent hydraulic equipment manufacturer, for reference:

1. Hydraulic oil leakage

1.1 Cause: aging of the seal ring, loose or damaged pipe connections.

1.2 Treatment method: Check and replace damaged seals. Tighten loose joints and replace damaged pipes if necessary.

2. Hydraulic oil temperature is too high

2.1 Cause: hydraulic oil pump overload, cooling system failure or oil contamination.

2.2 Treatment method: Check whether the oil pump is working properly and ensure that it operates within the specified load range. Check whether the cooling system is operating normally, such as whether the cooler is blocked. Replace or clean the contaminated hydraulic oil to keep the oil clean.

3. Unstable pressure

3.1 Cause: hydraulic valve failure, pipe blockage or poor hydraulic oil quality

3.2 Treatment: Check and clean or replace the faulty hydraulic valve. Check the pipeline to ensure that there is no blockage, and clean the pipeline if necessary. Replace the hydraulic oil to ensure that the oil that meets the requirements is used.

4. Slow action or no response

4.1 Cause: Insufficient hydraulic oil, bubbles entering the hydraulic system or hydraulic pump failure.

4.2 Treatment: Check the oil level and add hydraulic oil to the normal range. Eliminate bubbles in the hydraulic system to ensure that the system is well sealed. Check whether the hydraulic pump is working properly and repair or replace it if necessary.

5. Abnormal noise

5.1 Cause: Hydraulic oil contamination, hydraulic pump wear or bubbles.

5.2 Treatment: Check the cleanliness of the hydraulic oil and replace the oil if necessary. Check the operating condition of the hydraulic pump. If severe wear is found, it needs to be repaired or replaced.

6. Inaccurate control

6.1 Cause: Improper adjustment of the hydraulic valve or sensor failure.

6.1 Treatment: Check the setting of the hydraulic valve to ensure that it meets the working requirements. Check the sensor and electrical control system and calibrate or replace the faulty parts if necessary.

7. Vibration or abnormal movement

7.1 Cause: Cavitation or failure inside the hydraulic system.

7.2 Treatment: Check the hydraulic system to ensure that the oil is clean and free of bubbles. Check the connection and tightening of all parts to ensure that there is no looseness.
