hydraulic tank pressure and oil flow rate control

Hydraulic pressure at work to keep the tank hydraulic oil tank air pressure, the pressure must be maintained at random within the scope of the provisions of the manual. Insufficient pressure too low pump oil damage; when the pressure is too high the hydraulic system oil leakage, easy to create the low pressure oil duct. Maintenance of construction machinery and after the oil change, air in the exhaust system to randomly check the oil level of the provisions of the manual States, construction equipment parked on a flat place, engine check the oil level again after 15min and, if necessary, be supplemented.
