Description
Technical field
This utility model relates to fuel system equipment technical field, particularly relates to a kind of novel high reliability hydro pulse and delays
Rush device.
Background technology
Oil pressure pulsation damper is a machine slowing down vehicle fuel pipeline pressure, when fuel injector injection fuel oil,
Can produce fuel pressure pulsation in conveyance conduit, fuel pressure pulsation damper is to make fuel pressure pulsation decay, to weaken combustion
Pressure fluctuation transmission in oil conveyance conduit, reduces noise.Fire existing oil pressure pulsation damper reduce noise result and pay no attention to
Think, and owing to housing is metal material, during working long hours, be likely to have metal fillings or particulate contaminant is mixed in fuel oil
In can pollute fluid, and easy damaged electromotor makes equipment dependability poor in flowing to electromotor along with fluid.
Summary of the invention
According to above technical problem, this utility model provides a kind of novel high reliability oil pressure pulsation damper, including shell
Body, diaphragm, spring base, regulation screw, air chamber, fuel oil room, oil-in, oil-out, it is characterised in that: also include permanent magnetism
Sheet, filter screen and waveform molar, described enclosure interior offers air chamber, described air chamber be provided above fuel oil room, described
Air chamber is connected by diaphragm with fuel oil room, and described diaphragm is connected with permanent magnetism sheet, and the side of described fuel oil room offers oil-in,
Opposite side offers oil-out, and the inwall of described oil-in and oil-out is respectively arranged with waveform molar, described oil-in
Side is provided with filter screen, and described air chamber is internally provided with spring base, and described spring base is provided with the first spring, and described first
Spring is connected with one end of secondary spring, and the other end of described secondary spring is connected with diaphragm, and described spring base is by regulation spiral shell
Nail is connected with housing.
The beneficial effects of the utility model are: this utility model provides a kind of novel high reliability oil pressure pulsation damper,
Original oil pressure pulsation damper is improved, the oil-in inwall with oil-out sets up waveform molar, can effectively buffer
Oil pressure at oil-in, oil-out, reduces the generation of noise；Filter screen is set up, it is to avoid metal fillings or be mixed in fuel oil at oil-in
In particulate contaminant pollute further fluid, damage electromotor, improve equipment use reliability；Set up permanent magnetism sheet, with film
Sheet connects, and permanent magnetism sheet can be driven to move down when diaphragm is moved down by hydraulic pressure, adds permanent magnetism sheet and fluid
Contact area, makes fluid be fully contacted with permanent magnetism sheet, further avoids the metal impurities being mixed in the fluid dirt to fluid
Dye, improves the reliability that product uses, extends the service life of equipment simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
According to Fig. 1, this utility model is further described:
Such as Fig. 1, housing-1, diaphragm-2, air chamber-3, fuel oil room-4, oil-in-5, oil-out-6, waveform molar-7, filter
Net-8, spring base-9, the first spring-10, permanent magnetism sheet-11, secondary spring-12, regulation screw-13.
Embodiment 1
This utility model provide a kind of novel high reliability oil pressure pulsation damper, including housing 1, diaphragm 2, air chamber 3,
Fuel oil room 4, oil-in 5, oil-out 6, waveform molar 7, filter screen 8, spring base the 9, first spring 10, permanent magnetism sheet 11, secondary spring
12, regulation screw 13, first offers air chamber 3 inside housing 1 during installation, is provided above fuel oil room 4 at air chamber 3, logical
Crossing diaphragm 2 to be connected with fuel oil room 4 by air chamber 3, diaphragm 2 is connected with permanent magnetism sheet 11, and oil-in 5 is offered in the side of fuel oil room 4, separately
Side sets out hydraulic fluid port 6, is respectively provided with waveform molar 7 on the inwall of oil-in 5 and oil-out 6, and in the side of oil-in 5
Filter screen 8 is installed, spring base 9 is set inside air chamber 3, spring base 9 is installed the first spring 10, the first spring 10 and auxiliary bullet
One end of spring 12 connects, and the other end of secondary spring 12 is connected with diaphragm 2, and spring base 9 is by regulation screw 13 with housing 1 even
Connect.
Embodiment 2
During use, fuel oil is flowed in the fuel oil room 4 within housing 1 by oil-in 5, if the excessive fuel oil of fuel pressure can be to film
Sheet 2 applies downward power, and the first spring 10, the secondary spring 12 that connect below diaphragm 2 can be pulsed by this partial pressure of Passive intake,
After making oil pressure become steadily, oil-out 6 discharging, this sets up waveform molar at oil-in 5 with oil-out 6 in the process,
Can effectively buffer oil pressure, reduce the generation of noise；At oil-in 5, set up filter screen 8, it is to avoid metal fillings or be mixed in fuel oil
Grain thing impurity pollutes fluid, damage electromotor further, improves the reliability that equipment uses；Set up permanent magnetism sheet 11, with diaphragm 2 even
Connect, permanent magnetism sheet 11 can be driven when diaphragm 2 is moved down by hydraulic pressure to move down, add permanent magnetism sheet 11 and fluid
Contact area, makes fluid be fully contacted with permanent magnetism sheet 11, further avoids the metal impurities being mixed in fluid to fluid
Pollute, improve the reliability that product uses, extend the service life of equipment simultaneously.
The above is only preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from this utility model principle, it is also possible to make some improvement, these improve also should
It is considered as protection domain of the present utility model.
