Abstract
The utility model discloses a kind of oil pump with safety protection device; comprise oil pump; described oil pump is provided with the mounting hole of safety protection device; coordinate in described mounting hole and safety protection device is installed; described safety protection device comprises safety valve, safety valve spring, adjustment pad and valve plug, and described safety protection device is that the relief hole be provided with by oil pump carries out pressure release.The utility model provides a kind of oil pump with safety protection device, has structure simple, and processing, cost of production are low, assemble simple, easy to maintenance.Effectively can protect oil pump, maintain the balance of oil pressure in the pump housing.Avoid occurring that in the pump housing, oil pressure is excessive, cause oil pump to be damaged, shorten the phenomenon in oil pump working life.
Description
Technical field
The utility model relates to parts and components of diesel engine field, is specifically related to a kind of oil pump with safety protection device.
Background technique
When oil pump oil pressure in diesel engine unusual service condition or body oil duct crosses relative superiority or inferiority work, there will be oil pressure in the oil pump pump housing excessive, cause oil pump to be damaged, shorten the working life of oil pump, therefore need to increase safety protection device in oil pump.
Model utility content
The utility model object is exactly the defect in order to make up prior art; a kind of oil pump with safety protection device is provided; the utility model can pressure release when oil pressure is excessive in the oil pump pump housing; automatically pressure release is stopped when pressure arrives design standard value; maintain the balance of oil pressure in the pump housing, thus effectively protect oil pump.
In order to realize above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved by the following scheme:
A kind of oil pump with safety protection device; comprise oil pump; it is characterized in that: described oil pump is provided with the mounting hole of safety protection device; coordinate in described mounting hole and safety protection device is installed; described safety protection device comprises safety valve, safety valve spring, adjustment pad and valve plug, and described safety protection device is that the relief hole be provided with by oil pump carries out pressure release.
Described safety valve is connected with safety valve spring, and described safety valve spring is connected with adjustment pad, and described adjustment pad is connected with valve plug.
The adjustment of described vent pressure is completed by adjustment pad.
Compared with prior art, the beneficial effects of the utility model are:
The utility model provides a kind of oil pump with safety protection device, has structure simple, and processing, cost of production are low, assemble simple, easy to maintenance.Effectively can protect oil pump, maintain the balance of oil pressure in the pump housing.Avoid occurring that in the pump housing, oil pressure is excessive, cause oil pump to be damaged, shorten the phenomenon in oil pump working life.
Embodiment
Fig. 1 is the utility model overall structure schematic diagram.
In figure, 1. oil pump, 2. mounting hole, 3. protective gear, 4. safety valve, 5. safety valve spring, 6. adjust pad, 7. valve plug, 8. relief hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1; oil pump 1 is provided with the mounting hole 2 of safety protection device; coordinate in described mounting hole 2 and safety protection device 3 is installed; described safety protection device 3 is made up of safety valve 4, safety valve spring 5, adjustment pad 6 and valve plug 7, and described safety protection device 3 is that the relief hole 8 be provided with by oil pump 1 carries out pressure release.When pressure is excessive time, oil pressure withstands the valve body of safety valve 4, when the pressure of oil pressure is greater than the pressure of safety valve spring 5, will releasing pressure automatically, when the pressure after pressure release is less than the pressure of safety valve spring 5, automatically withstand under the force of a spring, when needs regulate vent pressure size, adjustment can be completed by the quantity of adjustment adjustment pad 6.
Claims (2)
