Care and maintenance of small hydraulic presses

1. Maintenance and maintenance of small hydraulic presses:

It is recommended to use No. 32 and No. 46 anti-wear hydraulic oil for working oil, and the operating oil temperature should be within the range of 15 to 60 degrees Celsius.

2. The oil must be strictly filtered before being allowed to be added to the tank.

3． The working oil should be replaced once a year, and the first replacement should not exceed three months;

4. The slider should always be filled with lubricating oil, the outer surface of the column should always be kept clean, and engine oil should be sprayed before each work.

5. The maximum allowable eccentricity of the concentrated load under the nominal pressure of 500T is 40mm. Excessive eccentricity can easily cause strain on the column or other adverse phenomena.

6． Calibrate and check the pressure gauge every six months;

7. If the machine is out of service for a long time, the surface of each adding part should be scrubbed clean and coated with anti-rust oil.

2: Safe operation matters for small hydraulic presses

1. Those who do not understand the structure, performance or operating procedures of the machine should not start the machine without authorization;

2. Small hydraulic presses should not be repaired or adjusted during operation;

3. The grounding of electrical equipment must be firm and reliable:

4. Do not use it with overload or exceeding the maximum eccentricity:

5. It is strictly prohibited to exceed the maximum stroke of the slider.

6. When the machine finds serious oil leakage or other abnormalities (such as unreliable movement, loud noise, vibration, etc.), it should stop the machine to analyze the cause and try to eliminate it. It is not allowed to go into production while sick:

7. At the end of each day's work: put the slider of the small hydraulic press to the lowest position
