Abstract
The utility model relates to a water pump lubricant supply device for a diesel engine water pump unit, which comprises a lubricant tank, an oil pump, an oil inlet pipe and an oil return pipe, wherein the oil pump is in transmission connection with a gear box driven by a diesel engine; an oil supply pipe is connected between the oil pump and the lubricant tank; the oil inlet pipe is connected between the oil pump and a water pump; and the oil return pipe is connected between the water pump and the lubricant tank. The lubricant supply device has the advantages that: the closed circulation is achieved, neither an external power supply nor other power sources are needed; and the lubricant supply device has a small volume, a simple structure and high reliability, is convenient to use, and is especially suitable for working under the working condition of loss of power.
Description
Technical field
The utility model relates to a kind of diesel pump unit water pump oil supply unit of lubricating oil, belongs to the machinery lubrication technical field.
Background technique
Existing common water pump is not because lift not high (lift generally is lower than 200m) needs oil supply unit of lubricating oil usually.(as: lift 1000～4000m) is according to the proportionality law of centrifugal pump: H and high-pressure water pump is owing to lift is too high

2, the high-pressure water pump rotating speed can be very high (rotating speed is general 〉=and 2950rpm), component such as water pump bearing need oil lubrication, so, the oil supplying device of water pump lubricant oil must be set.The fuel feeding of high-pressure water pump lubricant oil can realize by electric oil pump usually, but diesel-driven high-pressure water pump works under the dead electricity operating mode, and power supply can't be provided.
Summary of the invention
The purpose of this utility model is, overcome the difficulty of high-pressure water pump lubricant oil fuel feeding under the dead electricity operating mode, a kind of lubrication system proper functioning of guaranteeing high-pressure water pump is provided, thereby guarantees a kind of diesel pump unit water pump oil supply unit of lubricating oil of diesel pump unit functional reliability.
The technical solution of the utility model is:
A kind of diesel pump unit water pump oil supply unit of lubricating oil, it comprises lubricating oil tank and oil pump, also has oil inlet pipe, and return tube; Described oil pump be connected with diesel-driven gearbox drive; Be connected with fuel supply line between oil pump and the lubricating oil tank; Be connected with oil inlet pipe between oil pump and the water pump; Be connected with return tube between water pump and the lubricating oil tank.
Further technological scheme is:
It is that drivign belt connects that described diesel pump unit water pump oil supply unit of lubricating oil, its oil pump are connected with gearbox drive.
The utility model has the advantages that: described lubricant oil fuel feeding is a closed cycle, and the oil pump power source rotates from gear, does not need ABAP Adapter or other power; Also have, the utility model diesel pump unit water pump oil supply unit of lubricating oil volume is little, simple in structure, easy to use, reliability is high, is specially adapted to work under the dead electricity operating mode.
