The maintenance of the hydraulic system of the Double Layer Roll Forming Machine

 

1. Liquid level of the oil box should be above the oil’s mark center, avoid through the air cleaner remove the impurity when oil pump do air suction and refueling.


2. Can’t raise the pressure randomly

3. The working liquid in the oil box of the Double Layer Roll Forming Machine is No.20 anti-wear hydraulic oil. When the environment temperature is below 10 degree, use No.10 anti-wear hydraulic oil. When the environment temperature is higher than 40 degree, can use No.68 anti-wear hydraulic oil. Can’t use other oil instead.


4. The normal work oil temperature is 20-50 degree. When the oil temperature is too high, should adopt cooling methods (add cooling water or use electric fan blow) or stop the pump. Until the oil fully cooled, can re-use. When the oil temperature is too low, can’t use it directly, need to adopt heating methods. Can raise the temperature from outer heating.  


5. Keep the hydraulic oil clean, no impurity and water. If use frequently, need to wash the oil filter on time every month, wash oil box on time every six months and change the new oil.

6. When turn on the motor of the Double Layer Roll Forming Machine, need to set the selector valve to the middle part, to prevent the motor overload.


7. When use the hose, should avoid the hose to fold and bend. Can’t too close to the hose, to prevent suddenly broken and hurt people.


8. When the hose anti-pressure is 1.25 times lower than the rated pressure, or leaking, aging, we must stop use the hose, and change the new hose.


9.Overhauling once a year. Use the light diesel or kerosene to clean the accessories of the Double layer Roll Forming Machine, and notice the protection of the panels.
