Safety operation rules for hydraulic press
  1. machines that do not understand the structure, performance, or operation procedures of a machine shall not operate the machines without authorization.
  2. during the working process, the machine should not be overhauled and adjusted.
  3., when the machine found serious oil spills or other anomalies (such as small action, reliability, noise, vibration, etc.), should stop, analyze the reasons, try to rule out, do not allow sick to put into production.
  4. shall not overload or exceed the maximum offset use.
  5., no more than the maximum use of the slider (the minimum closing height of the die shall not be less than 450MM)
  6. grounding of electrical equipment must be firm and reliable.
  Maintenance of hydraulic press
  1. 30# hydraulic oil is recommended for working oil. If you choose mechanical oil or turbine oil, depending on the temperature. At room temperature below 20 degrees, use 20# mechanical oil or 22# turbine oil. When room temperature is higher than 30 degrees, 30# or 40# mechanical oil can be used. The oil temperature should be in the range of 15 degrees -65 centigrade.
  2. oil should be strictly filtered before adding fuel tank. The oil in the tank must not be lower than the oil mark. Fill the tank and fill it up to the oil return.
  3. work fluid should be replaced every six months. For the first time, the replacement should not be more than 2 months.
  4. column and exposed piston surface often spray oil. Spray before each work
  5. under the nominal force 3150KN, the maximum load is concentrated, the maximum allowable eccentricity is 40MM, and the eccentric is too large, which is easy to cause the column to pull or appear other bad phenomena.
  6. check the pressure gauge once every half a year.
  7. when the machine asks for a long time, when it is disabled, the surface should be scrubbed and coated with antirust oil. According to the shift, regular (2-3 months) check the filling valve, fixed nut, shall not be loose.
