Abstract
The invention relates to a diesel engine water pump improved device which comprises a pump body. The diesel engine water pump improved device is mainly characterized in that a through hole is formed in the middle of the pump body, a driving shaft is inserted in the through hole, the driving shaft and the pump body are located through a bearing, an oil seal is mounted on an outside shell at the outer end of the bearing, a water seal seat is mounted on the outside shell at the inner end of the bearing, a belt pulley is fixed to the outside top end of the driving shaft, an impeller is mounted on the inside of the driving shaft, an oil feed hole for filling lubricating oil and an oil return hole are further formed in the pump body, a reducing valve is arranged in the oil feed hole, the oil feed hole is communicated with an oil pressure pipeline of an engine through a pipeline, and the oil return hole is communicated with an oil sump of the engine through a pipeline.
Description
Technical field
The present invention relates to the engine water pump on a kind of diesel engine, especially relate to a kind of diesel pump improved device.
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 present invention well solves existingly exists technical problem.
Summary of the invention
The invention provides a kind of diesel pump improved device, 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.
The invention discloses a kind of diesel pump improved device, comprise a pump housing, be primarily characterized in that and be provided with through hole in the middle part of the described pump housing, live axle is fitted with in described through hole, described live axle is located mutually by bearing and the pump housing, the outside housing of described bearing outer end is provided with oil sealing, the outside housing of its bearing the inner is provided with water seal seat, described live axle outer tip end is fixed with belt pulley, the inner side of described live axle is provided with impeller, the described pump 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 invention provides a kind of diesel pump improved device, 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, lubricate for a long time owing to using the machine oil of engine interior, water pump can not be damaged because of not lubricating.
