Common faults and troubleshooting methods of hydraulic gate shears and maintenance of their systems

by:WORLD     2022-08-07

With the development of society, hydraulic guillotine shears have become the mainstream of manufacturers in various countries. All hydraulic guillotine shears will inevitably have some failures after a long time. So how do we solve the problems? Later What kind of maintenance is needed to avoid such problems? Next, the world press machine will be introduced to you.

Common faults and troubleshooting methods of hydraulic gate shears:

1. Check the gas pressure of the accumulator:

The gas pressure of the accumulator needs to be checked frequently. Use the nitrogen charging tool of the accumulator attached to the machine. If the nitrogen charging pressure is less than 4.5Mpa, it should be supplemented.

2. The accumulator is filled with oil during the use of the machine

If the accumulator is found to have insufficient oil filling pressure, it should be filled in time.

3. Sharpening and replacement of blades:

The blade must be sharpened on a regular basis, and if it is not sharpened for a long time, it seems to be easy, but it will actually cause a lot of waste. If the blade is cut bluntly and continues to cut, the outer grain structure of the blade will be damaged due to excessive pressure, which will damage the equipment and cannot obtain good cutting quality.

After the blade is sharpened, the damaged crystalline outer layer will be eliminated. Therefore, a complete blade sharpening schedule should be formulated according to the specific production situation. It is best to have a set of sharpened blades for spare, so as not to affect production. .

Maintenance of the hydraulic system:

1. Hydraulic circuit:

Regularly check the oil level of the fuel tank. If the oil level is lower than the center line of the oil mark, refuel to the center line of the oil mark immediately. After installation and test run, the first oil change must be carried out after working for one month, and it must be carried out every 2000 hours thereafter. Change the oil.

The hydraulic oil used must meet the requirements, its viscosity is 27~33 centistokes, and the oil tank must be thoroughly cleaned every time the oil is changed.

2. Oil filter:

Regularly clean the oil filter installed at the end of the oil inlet of the oil pump, and clean it with gasoline or trichloroethylene solution. If the oil filter component is seriously damaged, it must be replaced in time.

3. Air filter:

The air filter is installed on the fuel tank; the machine tool should be cleaned for the first time after being put into use for 500 hours, and should be washed with gasoline, vinyl chloride and other solutions. After 1000 hours, it must be cleaned once.

4. Inspection of mechanical parts:

All fasteners must be checked once a week for looseness and for lubrication and wear of the friction pair of the guide gauge. If any abnormal situation is found, it must be corrected immediately before it can be used.

5. Adjustment of safety relief valve:

In order to ensure the normal production of the shearing machine, the adjustment of the safety relief valve is very important, and it should be adjusted according to the maximum allowable working pressure.

The above is the relevant content of the common faults and troubleshooting methods of hydraulic gate shears and the maintenance of the system compiled by world press machine. I hope it will be helpful to you.
