Abstract
The utility model discloses a kind of machine oil refrigerating module housing that can weaken vortex phenomenon, the housing is provided with rotor of engine oil pump chamber, drain path, oil inlet passage, a boss is provided with the oil inlet passage, oil inlet passage is divided into two by the boss, form the first oil inlet passage and the second oil inlet passage, the drain path port of export communicates with the first oil inlet passage, the first oil inlet passage port of export communicates with the second oil inlet passage, and the second oil inlet passage port of export communicates with rotor of engine oil pump chamber.The housing of this structure can reduce impact of the drain path hydraulic oil to oil inlet passage low pressure oil, and also ensure that hydraulic oil is sufficiently mixed with low pressure oil before rotor chamber is entered.
Description
Technical field
It the utility model is related to a kind of machine oil refrigerating module housing.
Background technology
The pressure release mode generally use internal drainage type of machine oil pump discharge, the i.e. outlet when lubricating oil pump in traditional machine oil refrigerating module
When pressure exceedes pressure limiting valve opening pressure, pressure limiting valve is opened, and machine oil pump discharge is connected by drain path with oil inlet passage, high pressure
Oil returns to oil inlet passage by drain path, and hydraulic oil together enters rotor chamber after fully mixed with low pressure oil（See Fig. 1）.
But because machine oil cooling module structure limits, to save space, drain path is typically only capable to positioned opposite, draining with oil inlet passage
The low pressure oil of hydraulic oil and oil inlet passage in passage is directly liquidated, and the larger and strong whirlpool of area can be so produced in porch
Stream, lubricating oil pump oil suction difficulty, instability of flow, rotor is caused to produce a series of phenomenons for endangering product operation such as cavitation erosion.Therefore,
A kind of rational structure is needed to ensure product reliability of operation and stability.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems of the prior art, there is provided one kind can weaken vortex
The machine oil refrigerating module housing of phenomenon, the housing can reduce impact of the drain path hydraulic oil to oil inlet passage low pressure oil, from
And weaken the generation of vortex phenomenon.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：One kind can weaken vortex phenomenon
Machine oil refrigerating module housing, the housing be provided with rotor of engine oil pump chamber, drain path, oil inlet passage, the oil inlet passage
In be provided with a boss, oil inlet passage is divided into two by the boss, forms the first oil inlet passage and the second oil inlet passage, described to let out
Oily channel outlet communicates with the first oil inlet passage, and the first oil inlet passage port of export communicates with the second oil inlet passage, described
The second oil inlet passage port of export communicates with rotor of engine oil pump chamber.
Preferably, the drain path intersects with the first oil inlet passage in " people " font.
Preferably, the width of the drain path port of export is less than the width of the first oil inlet passage port of export.
Preferably, the width of the first oil inlet passage port of export is less than the width of the second oil inlet passage port of export.
Preferably, the width in the drain path stage casing is more than the width of the port of export.
The beneficial effects of the utility model are：The utility model in oil inlet passage by setting a boss, the boss
Oil inlet passage is divided into two, the machine oil of oil inlet is divided into two bursts of tributaries, enters respectively from two passages, drain path machine oil
Only liquidated with the machine oil in the first oil inlet passage, and on the machine oil in the second oil inlet passage without influence, due to the space that liquidates
Reduction, the intensity that liquidates substantially weakens, and caused vortex phenomenon accordingly also weakens.Entering by mixed machine oil for the first time
Further mixed with the machine oil in the second oil inlet passage before rotor chamber, vortes interference further reduces, so as to avoid lubricating oil pump
Oil suction difficulty, instability of flow, rotor produce the generation for phenomena such as cavitating.
