摘要： A gear type grease pump includes a motor fixed on the top surface of a base plate, a gear type pump fixed on the bottom surface of the base plate, the pump having a pair of gears engaged with each other and rotationally driven by the motor for rotating, a housing body and a bottom cover for accommodating the two gears, and a grease inlet and a grease outlet opposite to the grease inlet both provided on the housing body. A grease sweeping blade is located below the bottom cover and driven by the pump. A sealing ring is fixed along the bottom surface periphery of the base plate. A perforated mesh hood is located within the sealing ring and encloses the gear type pump and the grease sweeping blade. And a grease path is provided inside the base plate to communicate with the grease outlet path when the pump is fixed on the base plate, and the outlet of the grease path is connected with a conventional grease gun. Since the entire grease pump is loaded with grease, the grease having the tendency to flow into the grease inlet is fed into the pump, and the pump steadily squeezes out the grease.

摘要： A power grease pump having a rotary disk fixed on a base plate and rotating by a power device, and a rotary axis eccentrically mounted thereon. The pump unit includes a cylinder body with both ends being sealed and a piston assembly accommodated therein. One end of the cylinder body is pivotally mounted on a hollow column fixed on the base plate, near to the other end a plurality of longitudinal slotted holes are provided to penetrate the cylinder wall, and another longitudinally long slotted hole in which the rotary axis on the rotary disk passes and is connected with the piston assembly. A grease discharge hole located near the bottom dead center of the inner piston in corresponding piston assembly is provided on the cylinder body to penetrate the cylinder wall. A set of grease paths are provided in the piston assembly, cylinder body and hollow column, and are interconnected with one another. Thus, by rotating the rotary disk the pump assembly can be made to swing around the hollow column and sweep the grease of a grease barrel into the cylinder body while the piston assembly can be moved back and forth to squeeze out the grease in the cylinder body through the grease paths by high pressure.

摘要翻译： 一种电动润滑脂泵，其具有固定在基板上并由动力装置旋转的旋转盘和偏心地安装在其上的旋转轴。 泵单元包括两端密封的气缸体和容纳在其中的活塞组件。 圆筒体的一端可枢转地安装在固定在基板上的中空柱上，靠近另一端，设有多个纵向开槽孔以穿透气缸壁，另一个纵向长的开槽孔中旋转轴线 旋转盘通过并与活塞组件连接。 在缸体上设置有位于相应活塞组件内部活塞下死点附近的润滑脂排出孔，以便穿透气缸壁。 在活塞组件，缸体和空心柱中设置有一组油路，并且彼此相互连接。 因此，通过旋转旋转盘，可以使泵组件围绕中空柱摆动并将油脂筒的油脂吹扫到缸体中，同时活塞组件可前后移动以挤出缸体中的油脂 通过高压油路。
