How to replace the oil seal of the four-column hydraulic equipment?

When replacing the oil seal of the four-column hydraulic press machine, be sure to keep the inner lip of the stable oil seal from damage; 7 steps are given below. If you still do not understand, you can consult the hydraulic press machine manufacturer in time.

The oil seal in the four-column hydraulic equipment is a mechanical element used to seal the oil between the lubricating part and the output part to prevent leakage. It is a double lip oil seal with a rubber covered self tightening spring. The wearing parts need to be replaced regularly, so how to replace the oil seal of the four-column hydraulic equipment?

Four-column hydraulic press machine plunger oil seal replacement steps:

1. Press the start button to raise the working platform; use four equal-height wooden sticks to firmly support the working platform;

2. Remove the bolt between the plunger and the bottom of the platform;

3. Use a smooth flat-blade screwdriver to pry out the oil seal, and put the new oil seal into the oil seal groove as it is (the lip of the stable oil seal faces down);

4. Pull the operating rod by hand to separate the plunger from the platform, so that the plunger drops to the bottom of the oil seal;

5. Use the jog method to push the plunger tip to the lip of the oil seal, and use a smooth flat-blade screwdriver to press the inner lip of the oil seal to the periphery of the plunger

6. After confirming that the inner lip of the oil seal is completely pressed around the plunger, press the start button to raise the plunger;

7. Connect the bolts between the plunger and the platform, and take out the four supporting sticks

Interference of hydraulic system to hydraulic press machine

The circuit pressure is easy to fall down instantaneously, the main reason is that the valve inlet pressure is disturbed by the system pressure fluctuation,

As the core component of the hydraulic press machine, the hydraulic system is the key to the normal operation of the hydraulic press machine. The importance of the hydraulic system to the hydraulic press machine is self-evident, so what factors will the hydraulic system cause interference to the hydraulic press machine? The influence of the hydraulic system on the work of the hydraulic press machine.

The hydraulic system of the combined machine tool and the metallurgical machine usually has multiple cylinders working at the same time. The load of each cylinder is different, and the required pressure is also different. If the same oil source is used, it will definitely cause mutual pressure interference. Bringing an oil source will make the hydraulic system too complicated. The basic idea of ​​dealing with such problems is to isolate the hydraulic circuit that does not meet the working pressure through appropriate methods, so as to reduce the interference of the hydraulic system pressure on the performance of the hydraulic machine.

Because the one-way valve can maintain the high pressure of the hydraulic circuit without being disturbed by other factors, we usually use the one-way valve to isolate the hydraulic circuit. Setting a one-way valve can eliminate the fault. The pressure drop caused by the internal leakage keeps the circuit pressure stable all the time. With such analysis steps and proper improvement of the hydraulic system, the pressure disturbance caused by the hydraulic system should be greatly reduced, and the performance of the hydraulic press machine will also be improved to a certain extent.

How long does it take to replace the filter element of a 1200-ton four-column hydraulic press machine?

There are many parts of the 1200-ton four-column hydraulic press machine, which occupies a large proportion in the electrical industry. Today I want to share a special part filter. Any part has a lifespan, and the filter is no exception. The following analysis filters How often to replace? It will not affect the normal working efficiency of the 1200-ton four-column hydraulic press machine.

About how long the filter in the 1200-ton four-column hydraulic press machine needs to be replaced, the specific time should be judged according to the core device filter element in the filter. Under the long-term production operation of the hydraulic press machine, a large amount of pollutants will accumulate on the surface of the filter element, and these pollutants will cause the filter element to lose its original color. If the original color can be restored after cleaning, the filter can still be used. If the original color cannot be restored after cleaning, the filter needs to be replaced again.

In addition, the pollutants generated by the hydraulic press machine equipment during the filtration process will be reduced after long-term use, affecting the normal operation of the hydraulic press machine equipment. Then it also indicated the need to replace with a new screen.

Where is the best place to install the filter of the 1200-ton four-column hydraulic press machine? This issue is also of concern to users. You must know that the filter is mainly responsible for the filtering function of the hydraulic system, and is usually installed in the pressure oil circuit and return oil circuit of the hydraulic system, so as to have a better filtering effect. At the same time, the filter in the hydraulic press machine has a more important auxiliary role, that is, through the analysis of the types of residual pollutants on the filter, it helps us find the location of wear, analyze the root cause of hidden dangers as soon as possible, and solve the problem as soon as possible.
