When the cone crusher is working at the thin oil station, the oil of the cone crusher is sucked out from the fuel tank by the gear oil pump, and is directly sent to the lubrication point of the equipment through the check valve, the double-tube type oil filter and the plate oil cooler. The maximum working pressure of the petrol station is 0.4Mpa and the minimum working pressure is 0.1Mpa. The service pressure is determined by adjusting the safety valve according to the requirements of the lubrication point. When the working pressure of the oil station exceeds the set pressure of the safety valve, the safety valve will automatically open and the excess oil will flow back to the tank. The structure of the cone crusher thin oil station has the following characteristics: (1) The cone crusher thin oil station is equipped with a spare oil pump The cone crusher thin oil station has two oil pumps, one for work and one for standby. During the working of the cone crusher oil station, when the system pressure is lower than the set value of the pressure controller, the standby oil pump automatically starts to work, thus ensuring the lubrication demand of the cone crusher. (2) Double-tube mesh oil filter is set before the plate oil cooler The ability of the cone crusher oil station to pass through the oil filter is related to its viscosity. When the temperature of the oil is high, the viscosity is low, the passing ability is good, and the filtration effect is also good. Therefore, it is quite advantageous to filter and then cool. (3) Adopting a double-barrel type oil filter The double-barrel type oil filter has two sets of filter elements. A set of filter cartridges is working, and a set of filter cartridges is used. When the oil pressure difference of the cone crusher exceeds 0.05 MPa, the switching valve is manually opened to make the spare filter element work, and the original working filter element can be taken out for cleaning and replacement without stopping the machine. The oil filter has a compact structure, simple connection, no bypass, and convenient replacement. (4) Using a plate oil cooler (5) Magnetic filter device is installed at the oil return port (6) equipped with instrument and electric control box All the display instruments of the cone crusher thin oil station are installed on the instrument panel, showing clear and easy to observe. Two ordinary pressure gauge used to directly observe the pump, a pressure filtration; two pressure controller controls the hydraulic oil outlet, the oil pressure to achieve controlled; otherwise a bi-metal thermometer, an electrical contact to observe and control the oil tank. The cone crushing electrical control box is automatically controlled with the working system of the oil station. When working normally, the oil pump works and one spare. Sometimes when the fuel consumption of the equipment needs to increase for some reason, the oil pressure in the system drops. When the oil pressure drops to the set value, it is controlled by the upper limit point of a pressure controller, and the standby oil pump is automatically turned on to work with the working oil pump. The spare cone crusher oil pump automatically stops working until the oil pressure returns to normal. If the oil pressure continues to drop and falls to another pressure controller setting, the lower limit contact is turned on, an accident alarm is issued, and the host is interlocked. An electric contact bimetal thermometer is connected to the oil tank of the cone crusher oil station. According to the fuel supply temperature requirements, the highest and lowest limits can be adjusted. When the oil temperature drops to the lowest point, the heater is turned on manually, and when the oil temperature rises to the highest point, the heater automatically stops.
