Description
Technical field
The utility model relates to the engine water pump on a kind of diesel engine, especially relates to a kind of engine water pump.
Background technique
The engine water pump water pump be mounted on bavin motor is used to a kind of device of the cooling liquid driving engine interior, its structure is in water pump cover, arrange water pump shaft impeller and driven wheel, water pump spindle is arranged on water pump cover inside by bearing, it in the course of the work, it is the working state of the high load of high speed rotating due to water pump, must with the bearing charging-up lubricant oil of grease gun feed water pump inside within the regular hour, once forget oiling, bearing will damage, water pump is made to damage the heat radiation affecting motor, the utility model well solves existingly exists technical problem.
Summary of the invention
The utility model provides a kind of engine water pump, it mainly solves the working state that available engine water pump is the high load of high speed rotating, must with the bearing charging-up lubricant oil of grease gun feed water pump inside within the regular hour, once forget oiling, bearing will damage, and makes water pump damage the shortcoming affecting the heat radiation of motor.
Engine water pump of the present utility model, comprise a housing, be primarily characterized in that described housing central section is provided with through hole, live axle is fitted with in described through hole, described live axle is located mutually by bearing and housing, the outside housing outside housing of described bearing outer end being provided with its bearing the inner of oil sealing is provided with water seal, described live axle outer tip end is fixed with belt pulley, the inner side of described live axle is provided with impeller, described housing is also equipped with lubricant oil oil inlet hole and spill port, reduction valve is provided with in described oil inlet hole, described oil inlet hole is connected with the engine oil pressure pipeline of motor by pipeline, described spill port is connected with the oil sump of motor by pipeline.
The utility model provides engine water pump, ato unit, driven by engine water pump rotates together, the oil pump of engine interior also operates and makes motor produce oil pressure simultaneously, the machine oil with pressure is by the pipeline that is connected on water pump and after the decompression of reduction valve, enter water pump inside lubricate bearing, when the machine oil of water pump inside is too much, machine oil flows back in engine sump tank by the oil returning tube be connected on water pump cover, owing to using the machine oil of engine interior to lubricate for a long time, water pump can not be damaged because of not lubricating.
