vertical water pump with tubular bag

Abstract

This utility model discloses a vertical water pump for cylindrical bags, including a coupling. A pump shaft body is fixedly installed at the bottom of the coupling, and a bearing chamber bracket is rotatably connected to the outer wall of the pump shaft body. When lubricating oil is added to the bearing chamber of the vertical water pump for cylindrical bags, the rotating pump shaft body and coupling may entangle clothing and cause injury. If lubrication is not added in time, it can easily damage the equipment. To prevent accidental start-up of the rotating equipment and injury, it is necessary to shut off the power to the water pump, close the relevant high-pressure side valves, and install forced braking measures on the valve drive device. These measures are complex, difficult to implement, and take a long time to withdraw the equipment, which seriously affects work efficiency. In this case, the extension pipe for lubrication is inserted into the lubrication pipe body, and the first bolt is rotated to connect the lubrication pipe body and the extension pipe for lubrication. At this time, with the help of the extended lubrication pipe, the plug of the lubrication port can be opened to add lubricating oil to the bearing chamber of the water pump, avoiding close contact between the operator and the pump shaft body and the coupling.
