Brief description of problems needing attention in long-term operation of hydraulic system of hydraulic cold press

Date of release:2019-04-28 Author: Click:

Cold press is divided into screw cold press and hydraulic cold press. During this period, the screw cold press has a turbine, which needs long-term maintenance and is vulnerable. Hydraulic cold press is not easy to leak oil and need not be maintained again and again. It has high working power. However, let's assume that if we want to ensure that the hydraulic system of hydraulic press can work reliably for a long time, we need to pay attention to some application problems in the process of application. Xiaobian shares the specific contents of what problems should be paid attention to in the long-term operation of hydraulic systems such as hydraulic cold press, woodworking cold press, etc. in the following sections. Come and see if you are interested.

1。 Avoid air mixing into the system and drain the air mixing into the system in time。

Air entering the hydraulic system of hydraulic press will cause harmful consequences such as noise and oil oxidative degeneration。 It is necessary to choose methods to avoid air mixing, and the air mixed into the system is often discharged。

Second, we should always adhere to the cleanliness of oil.

Mixed impurities in the oil will cause the slide valve to be stuck, plug and save the small holes or cracks, which will make the hydraulic components not work properly, and worsen the wear and tear of the relative moving parts. In addition to the selection of oil filters and various equipment to avoid foreign impurities mixed into the system, it is also necessary to clean the filters and replace the stale oil on time. When the hydraulic system of hydraulic press is installed, the hydraulic components and pipes should be cleaned. After commissioning, it is better to remove the components and pipes, and then install them after careful cleaning.

3. Prevent leakage.

Leakage is not allowed, internal leakage is inevitable, but its leakage can not exceed the allowable value, assuming that too much leakage, will not rise the pressure, the hydraulic engine can not reach the expected force (or moment). Moreover, the amount of oil leakage is related to the concave and convex pressure, which makes the movement of the working parts unstable. In addition, due to excessive leakage, volume loss increases and oil temperature increases. In order to avoid excessive leakage defects, it is necessary to make appropriate space between relative moving parts and install appropriate sealing equipment.

4. Prevent excessive oil temperature.

The oil temperature of hydraulic system of general hydraulic press should be 15-50 C. Excessive oil temperature will bring a series of adverse consequences.

The rise of oil temperature will dilute the oil, increase the leakage and decrease the power of the system. Oil operates at relatively high temperatures and briefly metamorphoses. In order to avoid excessive oil temperature, in addition to the method of avoiding oil heating (such as unloading of oil pump and volume speed regulation of high-power system) in the planning, it is also necessary to consider whether the tank has satisfactory heat dissipation. When required, additional cooling equipment can be installed.
