Description
Technical field
This utility model relates to a kind of diesel-driven generator oil supply system, and concrete exempts from air-discharging for a kind of diesel generating set
Oil supply system.
Background technology
Air in oil pipe and diesel fuel filter must be discharged, not so after stopping working because of oil starvation by current diesel-driven generator
Diesel-driven generator cannot work, and the method for currently employed air-discharging has following three kinds.
1, after fuel tank fills it up with oil, the oil pipe entering injection pump is pulled out, after allowing the oil of oil pipe flow out, again install oil pipe.
The method has the disadvantage in that 1) need instrument to carry out manual operation；2) fuel oil can flow out, and produces environmental pollution, although also
With a container, the fuel oil flowed out can be collected, but still the problem that existence can increase work burden；3) skin of people can connect
Touch diesel oil, or suck diesel oil, the health of the mankind is produced impact.
2, installing a threeway between fuel tank and injection pump additional, 2 outlets of threeway, 1 connects injection pump, and other 1 connects
Oil pipe returns to fuel tank.The Chinese patent of Publication No. CN 202768194U discloses one to be had and exempts from air-discharging formula diesel oil fuel feeding
The electromotor of system, it is characterised in that including: the filter element, the entrance that are connected with the oil-out of diesel oil tank are fuel-displaced with this filter element
Mouthful threeway being connected, the oil pump being connected with the first of this threeway the outlet, the atomizer that is connected with this oil delivery side of pump；This threeway
Second outlet is connected with the oil return opening of described fuel tank.The defect that the method exists is as follows:
1) threeway is installed between fuel tank and injection pump additional, then between threeway and injection pump, still there is a bit of oil
Pipe, and this oil pipe has air；
2) injection pump is in the process of oil suction, as long as in the import department of pump, is likely to be sucked into, owing to there is threeway,
Threeway couples fuel tank, and fuel tank communicates with air and (if be not communicated with, then fuel oil does not just flow out, causes unit to open
Dynamic), so can there is a problem in that injection pump is possible to air inspiration oil pump in the process of oil suction, and in oil spout
Journey, arises that oil spout is discontinuous, and oil spout is erratic, and (when running into spray air, rotating speed can decline, and and then injection pump can add
Big distributive value improves the rotating speed of diesel engine) can cause that machine rotational speed is unstable, discharge frequency changes greatly, noise, diesel combustion
Incomplete pellets etc. pollute；And make unit parts frosted strengthen, affect unit reliability, shorten making of machine
Use the life-span.
3, directly utilize startup driven by motor bent axle rotation to empty.Its shortcoming existed is as follows:
1) often there is air in oil pipe, air can enter oil pump；
2) it extends the machine startup time, shortens the service life starting motor；
3) on startup, the air in oil pipe is easily caused diesel oil and chokes oil nozzle to death；
4) the machine startup time extended, it is easily caused accumulator because power shortage problem occurs in long-time startup.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of diesel generating set to exempt from air-discharging oil supply system, energy
Enough avoid air in the oil supply system of the process entrance diesel engine of injection pump oil suction, it is ensured that unit operation is steady, and promoting unit can
By property, promote the economy of unit, reduce noise and the pollution of inhalable particles.
For reaching above-mentioned purpose, this utility model following technical scheme of offer:
A kind of diesel generating set exempts from air-discharging oil supply system, including the fuel oil filter being connected with fuel tank oil-out, band
There is the injection pump of evacuation port and for being atomized the fuel injector of hydraulic oil, the oil-out of described fuel oil filter and described injection pump
It is provided with main oil pipe between oil-in to be connected, is provided with the first oil return pipe between the evacuation port of described injection pump with described fuel tank and is connected,
The hydraulic oil outlet of described injection pump be provided with high-pressure oil pipe between described fuel injector and be connected, described first oil return pipe is provided with list
To valve, or described first oil return pipe is provided with the first oil circuit breaker.
Further, described fuel oil filter is arranged in described fuel tank and is arranged on described fuel tank oil-out, and described
The second oil circuit breaker it is provided with at fuel tank oil-out.
Further, described fuel tank oil-out being connected with flowline, described fuel oil filter is connected with described flowline.
Further, the second oil return pipe it is provided with between described fuel injector and described fuel tank.
The beneficial effects of the utility model are:
Diesel generating set of the present utility model exempts from air-discharging oil supply system, by using the injection pump of band evacuation port, and
Check valve or the first oil circuit breaker are set on the first oil return pipe between injection pump evacuation port and fuel tank, it is possible to effectively guarantee oil pipe
In air discharged by evacuation port and the first oil return pipe, and check valve or the first oil circuit breaker effect under be prevented from sky
Gas enters, even if because oil starvation stops working, and also can horse back starter-generator group；I.e. it can be avoided that air is in the process of injection pump oil suction
Enter the oil supply system of diesel engine, it is ensured that operating steadily of unit, promote unit reliability, promote the economy of unit, reduce
Noise and the pollution of inhalable particles.
