Out the oil in the hydraulic oil pump pu from inside the cylinder, through a one-way valve is divided into two road, one after three to switch into the hydraulic cylinder, the valve is closed under normal doesn't work, it is as another three to the standby switch. Another oil through a three-way switch, when the location of the switch on the left side of oil can be through the valve. The detailed information on hydraulic system of rotary kiln is as follows: On the right position when the oil will return to the cylinder.The location of the middle oil.At the entrance of the three-way switch and even the oil pressure gauge, at the entrance of the three-way switch and return pipe string, there is a pressure relief valve used for overload protection. Whether pressure feed back or oil will have to make the oil filter. On three to switch back to oil pipeline is also equipped with one-way valve, and then through the check valve, filter, and oil, oil into the cylinder before filtering, the check valve is the filter resistance is larger or jams will be used.
After the hydraulic oil out of the filter, the oil after a manual and electric two-way switch valve can enter into the hydraulic cylinder, on the edge of the manual valve with a manual switch, manual switch in the leakage of the oil drain valve will be used. Hydraulic oil into the hydraulic cylinder of the line and also have two
