Abstract
The invention provides an oil pressure pulsation damper which comprises a shell, a membrane and the like. The oil pressure pulsation damper is characterized in that the pulsation damper further comprises a first spring, a second spring, an auxiliary spring, a permanent magnet and pressure gages; an air chamber is formed in the shell; a fuel oil chamber is arranged above the air chamber; and the air chamber and the fuel oil chamber are connected through the membrane. By means of the oil pressure pulsation damper, the pressure gages are additionally arranged at the positions of an oil inlet and an oil outlet pipe, fuel oil pressure can be visually displayed in times of oil feeding and oil discharging, users can know the working state of the oil pressure pulsation damper visually, and thus maintenance work is facilitated during fault diagnosis and maintenance. Due to arrangement of the permanent magnet, the phenomena that metal chips fall off and are mixed into fuel oil, and accordingly the oil can be polluted and an engine can be damaged are avoided, and the using reliability of equipment is improved; the double-acting springs are connected with the membrane, bearing capacity of the springs is enhanced, the pulsation sensing speed is high, and the using reliability and pressure regulating buffering precision of products are improved; and meanwhile, the service life of the equipment is prolonged.
Description
Technical field
The present invention relates to fuel system equipment technical field, more particularly to a kind of oil pressure pulsation damper.
Background technology
Oil pressure pulsation damper is a machine for slowing down vehicle fuel pipeline pressure, when fuel injector sprays fuel oil, fuel pressure pulsation can be produced in conveyance conduit, fuel pressure pulsation damper is to make fuel pressure pulsation decay, pressure fluctuation transmission in weaken fuel delivery line, reduces noise.Fuel pressure, pulsation too conference make oil pressure regulator operating time.The effect of oil pressure pulsation damper is exactly to reduce the pulsation of oil pressure and microseismic noise in fuel pipe, and can after engine stop keep having certain fixation pressure in oil circuit, is beneficial to resetting for electromotor.Because housing is metal material, the coat of metal is likely to have during working long hours or metal fillings drops, being mixed in fuel oil can pollute fluid, the metal fillings in fluid to filter out also can flow to easy damaged electromotor in electromotor with fluid；And user intuitively observes the working condition for understanding oil pressure pulsation damper, if electromotor breaks down, maintainer must one by one be tested, investigate each several part part, more be bothered；Having in traditional oil pressure pulsation damper be connected a spring with diaphragm, and pulsation feeling ability causes more slowly buffering pressure regulation accuracy not high.
The content of the invention
According to above technical problem, the present invention provides a kind of oil pressure pulsation damper, including housing, diaphragm, spring base, adjusting screw, air chamber, fuel oil room, oil-in, oil-out, it is characterised in that：Also include the first spring, second spring, secondary spring, permanent magnet and piezometer, the enclosure interior offers air chamber, fuel oil room is provided with above the air chamber, the air chamber is connected with fuel oil room by diaphragm, the side of the fuel oil room offers oil-in, opposite side offers oil-out, piezometer is separately installed with the oil-in and oil-out, the fuel oil chamber interior is provided with permanent magnet, the air chamber is internally provided with spring base, first spring is installed on the spring base, the side of first spring is provided with second spring, first spring and second spring are connected respectively with one end of secondary spring, the other end of the secondary spring is connected with diaphragm, the spring base is connected by adjusting screw with housing.
Beneficial effects of the present invention are：The present invention provides a kind of oil pressure pulsation damper, original oil pressure pulsation damper is improved, piezometer is set up at fluid import and flowline, intuitively show oil-feed with it is fuel-displaced when fuel oil oil pressure, user can get information about the working condition of the present invention, and maintenance work is conveniently carried out when fault diagnosis is keeped in repair；Permanent magnet is internally provided with housing, it is to avoid the housing of metal material has metal fillings pollution fluid, the damage electromotor that the coat of metal or metal fillings drop or be mixed in fuel oil, the reliability that raising equipment is used during working long hours；Using double-acting spring is logical, secondary spring and diaphragm connection, the ability to bear of spring strengthens, the reliability that pulsation impression is fast, improve product uses, the precision of buffering pressure regulation, while extending the service life of equipment.
Description of the drawings
Fig. 1 is the structural representation of the present invention.

Embodiment 2
When using, fuel oil is flowed in the fuel oil room 4 inside housing 1 by oil-in 5, if the excessive fuel oil of fuel pressure can apply downward power to diaphragm 2, first spring 10 of the lower section of diaphragm 2 connection, second spring 11, secondary spring 12 can Passive intake this partial pressure pulsation, after making oil pressure become steady, discharged by oil-out 6, in the process permanent magnet 8 can adsorb the metal fillings in fluid, metal fillings is avoided with fluid flow impaired electromotor, and the piezometer 7 by arranging on oil-in 5 and oil-out 6, user is allowd to get information about the working condition of equipment, facilitate the carrying out of maintenance work.
