Hydraulic press pressure is insufficient? Common faults and solutions master!

Ⅰ.The common causes of insufficient hydraulic pressure

Insufficient hydraulic press pressure is a common fault problem in many industrial production, which directly affects production efficiency and processing quality. When the hydraulic press cannot reach the required pressure, it may cause the equipment to fail to work normally, and even cause production to stall. Understanding the common failure causes of insufficient hydraulic press pressure is the first step to solve the problem.

The following are common reasons for insufficient hydraulic press pressure:

1. Insufficient hydraulic oil or oil quality problems

Insufficient hydraulic oil or oil quality is a common cause of insufficient hydraulic press pressure. Hydraulic oil plays an important role in the hydraulic system, which not only transmits pressure, but also plays the role of lubrication and cooling. When the quantity of hydraulic oil is insufficient or the quality is not up to standard, the pressure of the system will be affected.

2. The oil pump is faulty

Hydraulic oil pump is one of the core components of hydraulic system, which is responsible for pressurizing hydraulic oil into the system. If the oil pump fails, such as internal leakage, wear, stuck, etc., it may cause the hydraulic press to fail to reach the required pressure.

3. The hydraulic valve is faulty

Hydraulic valves are used to control the direction, pressure and flow of oil flow. If the hydraulic valve fails, such as the spool stuck, the seal is not strict or the adjustment is improper, it may lead to the pressure of the hydraulic press is unstable or insufficient.

4. Pipe leaks

If the pipeline in the hydraulic system leaks, the hydraulic oil will not be able to effectively transfer pressure, resulting in a drop in system pressure. Pipe leakage may be caused by loose pipe joints, aging or damaged seals.

5. System pollution

Pollutants in the hydraulic system, such as metal chips, dirt, air, etc., can lead to the blockage or wear of the hydraulic pump and valve, which affects the transfer of pressure and the normal operation of the system.

Ⅱ.the solution of insufficient hydraulic pressure

For the problem of insufficient pressure of hydraulic press, it can be investigated and repaired by the following methods:

1. Check and replace the hydraulic oil

Checking the liquid level and quality of hydraulic oil regularly is the basic measure to ensure the normal operation of hydraulic system. If it is found that the hydraulic oil is insufficient or the oil quality is poor, the hydraulic oil should be supplemented or replaced in time. In addition, the hydraulic oil that meets the requirements of the equipment should be selected, and the oil should be clean to avoid pollutants entering the system.

2. Repair the oil pump

The failure of oil pump is one of the important reasons for the insufficient pressure of hydraulic press. Check the working status of the oil pump regularly to ensure the tightness and flow of the oil pump. If it is found that there is leakage or wear inside the oil pump, it should be replaced or repaired in time.

3. Clean and adjust the hydraulic valve

Hydraulic valve failure is also a common cause of insufficient pressure. Check the cleanliness and working status of the spool regularly. If it is found that the valve is stuck or sealed poorly, the valve should be cleaned or replaced. At the same time, adjust the pressure setting value of the valve according to the actual work needs to ensure the normal pressure of the system.

4. Repair pipe leaks

Check the lines of the hydraulic system, especially the connection points and pipe joints, to ensure that there are no leaks. If leaks are found, repair or replace damaged pipes and seals in a timely manner. Check the integrity of the pipeline regularly to avoid pressure drop due to aging or damage of the pipeline.

5. Clean the system of contaminants

Contaminants in the hydraulic system can lead to equipment failure and reduced efficiency. Therefore, clean the hydraulic tank and filter regularly to ensure that there are no foreign objects and contaminants in the system. If necessary, the system can be fully cleaned to restore its normal working state.

Ⅲ.How to prevent insufficient pressure of hydraulic press?

In addition to the repair of common faults, regular maintenance and maintenance is an important means to prevent insufficient pressure of hydraulic press. The following are some suggestions for hydraulic press maintenance:

1. Check and replace hydraulic oil regularly

Periodically check the oil level and oil quality of the hydraulic oil to ensure that it meets the requirements. The replacement cycle of hydraulic oil is generally provided by the equipment manufacturer, and the replacement of hydraulic oil on time can extend the service life of the hydraulic system.

2. Check oil pumps and valves regularly

Check the operation status of the oil pump and hydraulic valve regularly to ensure that they are working normally. Especially for the tightness of the oil pump and the adjustment of the valve, timely detection of problems and treatment.

3. Clean the filter and fuel tank

The filters and fuel tanks in the hydraulic system need to be cleaned regularly to remove impurities and contaminants from them. You can use a special cleaning solution for cleaning and check if the filter needs to be replaced.

4. Check pipe connections

Check the lines and connection points of the hydraulic system regularly to ensure that there are no leaks and looseness. Check the status of the seals and replace the aging seals in time to avoid hydraulic oil leakage.

The problem of insufficient hydraulic pressure can be caused by a variety of factors, including insufficient hydraulic oil, oil pump failure, hydraulic valve failure, pipeline leakage and system contamination. Through regular maintenance and investigation, timely discovery and solution of these problems can effectively prevent the occurrence of insufficient pressure and improve the work efficiency and service life of the hydraulic press.

If your hydraulic press has insufficient pressure, do not ignore it, immediately troubleshoot and repair it to ensure the normal operation of the equipment and avoid affecting the production schedule.
