Abstract
The utility model provides an oil pressure pulsation damper, includes casing, diaphragm etc. Its characterized in that: still include first spring, second spring, secondary spring, permanent magnet and pressure gauge, the inside air chamber of having offered of casing, the top of air chamber is provided with the fuel room, the air chamber passes through the diaphragm with the fuel room and is connected. The utility model discloses add the pressure gauge in fluid import with going out oil pipe department, audio -visual demonstration oil feed oil -fired oil pressure when producing oil, the user can audio -visually know the utility model discloses an operating condition conveniently carries out maintenance work when failure diagnosis keeps in repair, be provided with the permanent magnet, avoid the metal fillings to drop, mix the reliability of polluting fluid, damage engine, improve equipment use in the fuel, the adoption double acting spring be connected with the diaphragm, and the reliability of product use, the precision of buffering pressure regulating have been experienced soon, have been improved in the carrying capacity reinforcing of spring, pulsation, has prolonged the life of equipment simultaneously.
Description
Technical field
The utility model relates to oil-fired system equipment technical field, particularly relates to a kind of oil pressure pulsation damper.
Background technique
Oil pressure pulsation damper is a machine slowing down vehicle fuel pipeline pressure, when oil sprayer injected fuel, fuel pressure pulsation can be produced in conveyance conduit, fuel pressure pulsation damper makes fuel pressure attenuate pulsations, to weaken the pressure pulsation transmission in fuel delivery line, reduce noise.Fuel pressure, too conference of pulsing make oil pressure regulator operating time.The effect of oil pressure pulsation damper is exactly the pulsation and the microseismic noise that reduce oil pressure in fuel pipe, and can keep there is certain fixation pressure in oil circuit after engine stop, is beneficial to resetting of motor.Because housing is metal material, probably have the coat of metal or metal fillings to drop, be mixed in fuel oil and can pollute fluid in the process of working long hours, the metal fillings for filtering out in fluid also can flow to easy damaged motor in motor along with fluid; And user observes the working state understanding oil pressure pulsation damper intuitively, if motor breaks down, maintenance man must test one by one, investigate each several part part, comparatively bothers; Have the spring that to be connected with diaphragm in traditional oil pressure pulsation damper, pulsation feeling ability causes buffering pressure regulation accuracy not high more slowly.
Summary of the invention
According to above technical problem, the utility model provides a kind of oil pressure pulsation damper, comprise housing, diaphragm, spring seat, adjusting screw, air chamber, fuel oil room, filler opening, oil outlet, it is characterized in that: also comprise the first spring, second spring, secondary spring, permanent magnet and pressure meter, described enclosure interior offers air chamber, the top of described air chamber is provided with fuel oil room, described air chamber is connected by diaphragm with fuel oil room, the side of described fuel oil room offers filler opening, opposite side offers oil outlet, described filler opening and oil outlet are separately installed with pressure meter, described fuel oil chamber interior is provided with permanent magnet, described air chamber inside is provided with spring seat, described spring seat is provided with the first spring, the side of described first spring is provided with the second spring, described first spring is connected with one end of secondary spring respectively with the second spring, the other end of described secondary spring is connected with diaphragm, described spring seat is connected with housing by adjusting screw.
The beneficial effects of the utility model are: the utility model provides a kind of oil pressure pulsation damper, original oil pressure pulsation damper is improved, pressure meter is set up in fluid import and oil outlet tube place, show oil-feed intuitively and fuel-displaced time fuel oil oil pressure, user can get information about working state of the present utility model, conveniently carries out maintenance work when fault diagnosis is keeped in repair; The inside of housing is provided with permanent magnet, avoids the housing of metal material in the process of working long hours, have the coat of metal or metal fillings to drop or be mixed in metal fillings pollution fluid, the damage motor in fuel oil, improving the reliability of equipment use; Employing double-acting spring leads to, secondary spring is connected with diaphragm, and the reliability that the ability to bear of spring strengthens, product use is experienced soon, improve in pulsation, the precision of buffering pressure regulation, extend the working life of equipment simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, housing-1, diaphragm-2, air chamber-3, fuel oil room-4, filler opening-5, oil outlet-6, pressure meter-7, permanent magnet-8, spring seat-9, the first spring-10, the second spring-11, secondary spring-12, adjusting screw-13.
Embodiment 1
The utility model provides a kind of oil pressure pulsation damper, comprise housing 1, diaphragm 2, air chamber 3, fuel oil room 4, filler opening 5, oil outlet 6, pressure meter 7, permanent magnet 8, spring seat 9, first spring 10, second spring 11, secondary spring 12, adjusting screw 13, housing 1 inside offers air chamber 3, the top of air chamber 3 is provided with fuel oil room 4, air chamber 3 is connected by diaphragm 2 with fuel oil room 4, filler opening 5 is offered in the side of fuel oil room 4, opposite side sets out hydraulic fluid port 6, filler opening 5 and oil outlet 6 distinguish setting pressure meter 7, permanent magnet 8 is installed in inside, fuel oil room 4, air chamber 3 inside arranges spring seat 9, spring seat 9 is provided with the first spring 10, the second spring 11 is installed in the side of the first spring 10, first spring 10 is connected with one end of secondary spring 12 respectively with the second spring 11, the other end of secondary spring 12 is connected with diaphragm 2, spring seat 9 is connected with housing 1 by adjusting screw 13.
Embodiment 2
During use, fuel oil flows in the fuel oil room 4 of housing 1 inside by filler opening 5, if the excessive fuel oil of fuel pressure can apply downward power to diaphragm 2, the first spring 10 connected below diaphragm 2, second spring 11, this part pressure pulsation of secondary spring 12 meeting Passive intake, oil pressure is become steadily, discharged by oil outlet 6, permanent magnet 8 can adsorb the metal fillings in fluid in the process, avoid metal fillings with fluid flow impaired motor, and the pressure meter 7 by filler opening 5 and oil outlet 6 are arranged, make user can get information about the working state of equipment, the carrying out of convenient for maintaining work.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
