Description

Anti-reversing fastening device of slurry pump
Technical Field
The utility model relates to a sediment stuff pump prevents reversing fastener belongs to power equipment technical field.
Background
The blast furnace front slag slurry pump is positioned in a pit with the depth of 6 meters, granulated slag flushing water is seriously corroded, more particles exist, the water temperature is high, a check valve in front of the water pump is corroded, the sealing surface of the check valve is not tight, and water in the check valve reversely flows, so that the water pump is reversed; meanwhile, the position of the check valve is far away from the outlet of the pump, and a certain residual pressure is generated from the outlet of the pump to the pipeline of the check valve section, so that the possibility of reverse rotation of the pump is increased. At present, a slurry pump is locked and anti-loose at the driving end of a main shaft of a water pump by using a single round nut, and can meet the self-locking condition under the action of static load. However, when the water pump is impacted, vibrated or subjected to variable load, the connection can be automatically loosened, and the anti-loosening effect is poor, so that the water pump is reversed. In addition, due to the production process, the slurry pump needs to be started and stopped frequently, the water pump can be reversed due to the action of inertia when the water pump is stopped, the round nut is not firmly fastened, and the power and the space of the movement of the main shaft are multiplied. When the reverse rotation occurs and the middle impeller moves forward, the impeller and the shell are scraped and collided, the impeller is fixed at a certain position, but the shaft still rotates at a high speed, and the power during the reverse rotation is higher than the power during the forward rotation, so that the hub of the impeller is finally broken, parts such as bearings and the like are damaged, the main shaft is damaged, even related facilities such as process pipelines and valves are damaged, and the safe operation of a pump station is seriously influenced. Therefore, the slurry pump reverse rotation prevention fastening device needs to be designed, when the water pump is powered off or in an accident situation, the water pump can be effectively braked to reverse, and the disassembly and the assembly are convenient, so that the occurrence of reverse rotation accidents of the water pump is reduced, and the use efficiency and the safety of the water pump are improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a sediment stuff pump prevents to reverse fastener is provided, can effectively brake the water pump when water pump outage or unexpected condition and reverse, it is all more convenient to dismantle the installation to reduce the emergence that the water pump reversed the accident, improve the availability factor and the security of water pump.
The technical scheme of the utility model is that:
