Structural features of the pump shaft and bearing and stuffing box of YCB arc gear oil pump

YCB arc gear oil pump pump shaft, pump shaft is the energy transfer component, made of high quality carbon steel. The pump shaft of the large YCB arc gear pump is hollow. The shaft hole is used to operate the oil pipe of the blade adjustment mechanism or the pump shaft of the YCB arc gear pump and the structural characteristics of the stuffing box. YCB arc gear pump The shaft and pump shaft are the parts that transfer energy and are made of high quality carbon steel. The pump shaft of the large YCB arc gear oil pump is hollow. The shaft hole is used to install the operation oil pipe of the blade adjustment mechanism or the bearing of the YCB arc gear oil pump. There are two types of bearings for the YCB arc gear oil pump: Bearings, the other type is thrust bearings. The role of the guide bearing is to position radially while receiving the radial force of the rotating portion. Medium and small axial flow rafts generally use rubber guide bearings, which are oil-lubricated plain bearings. The thrust bearing is mainly used to bear the weight of the rotating part of the oil pump and the axial oil pressure exerted on the blade by the oil flow, and transmit the force to the motor beam through the motor seat. It consists of a bearing housing and a rubber bushing. The inner surface of the rubber bushing is provided with a plurality of longitudinal grooves, which are or made of polygons for lubrication and cooling. The guide bearing is divided into upper and lower two, and the lower guide bearing is installed in the vane hub.
The upper guide bearing passes through the upper part of the oil-bending pipe of the pump shaft and is higher than the oil level of the oil inlet. The oil pump must be cleaned and lubricated before starting the oil pump. After the oil pump is started, the oil can be stopped. After the rubber bearing wears, it should be repaired or replaced in time. Be careful not to touch oily substances during use.
The stuffing box of the YCB arc gear oil pump is provided with a stuffing box at the oil elbow of the YCB arc gear oil pump, which is similar in form to the stuffing box of the centrifugal pump. Generally consists of packing box, packing and gland. There is no oil sealing tube and oil sealing ring. The high pressure oil flowing through the elbow directly infiltrates the packing to cool and lubricate.
