There may be many reasons for the lack of pressure in the hydraulic press. The following are some common reasons and solutions:

  1. Insufficient hydraulic fluid in the hydraulic system or hydraulic fluid contamination causes insufficient pressure. At this time, it is necessary to check whether the amount of hydraulic oil is sufficient, clean or replace the hydraulic oil, and keep the hydraulic oil clean.

  2. The hydraulic pump is damaged. At this time, it is necessary to check the working status of the hydraulic pump, such as the need to replace the hydraulic pump.

  3. The oil circuit in the hydraulic system is blocked, such as oil pipes, oil circuits, valves, etc. At this time, it is necessary to check whether the oil circuit is unobstructed, and clean or replace the blocked parts in time.

  4. Infusion of oil and gas in the hydraulic system results in insufficient pressure. At this time, it is necessary to exhaust and remove the gas in the hydraulic system.

  5. Some parts of the hydraulic system are damaged or fail, such as valves, seals, cylinders, etc. At this time, it is necessary to check and replace or repair the relevant parts.

In short, to solve the problem that the hydraulic press has no pressure, it is necessary to investigate the possible causes one by one and take corresponding solutions. In daily use, it is also necessary to maintain the hydraulic press regularly to ensure the normal operation of the hydraulic system.
