Description
Technical field
The utility model relates to the auxiliary starting system of diesel generator, especially a kind of diesel generator comperssed air starting system.
Background technique
Diesel generator utilizes diesel engine drives generator to produce the equipment of electric energy, has and start rapidly, invest less, the advantages such as operation and maintenance is convenient, be widely used in communication, dig up mine, build the road, forest zone, field irrigation, the field such as field construction.
For large-sized diesel generator, traditional start up system is difficult to ensure that its startup system under cryogenic can, therefore, need by auxiliary starting systems such as air startings, at dust storm comparatively large and the poor area of other air qualities uses time, the impurity such as gravel, oil, water easily enter in unit by air starting system, damage the devices such as solenoid valve, affect the normal Start-up and operating performance of generator set.
Model utility content
In view of this, the utility model provides a kind of diesel generator comperssed air starting system, can ensure the startability under diesel generator cryogenic conditions, meanwhile, prevents impurity to be mixed in unit.
Its technological scheme is as follows:
A kind of diesel generator comperssed air starting system, comprise black starting-up small generation set, air compressor, gas holder and pressure regulator valve, wherein, black starting-up small generation set is used for powering for air compressor, air compressor is communicated with gas holder, and pressure regulator valve is arranged on gas holder rear end, and is connected with pneumatic motor by pipeline, describedly be connected with oil and water seperator between this air compressor and gas holder, pressure regulator valve rear end is provided with y-type filter.
Adopt above structure, utilize comperssed air starting, ensure that diesel generator startability under cryogenic, pressurized air stores with gas holder after oil and water seperator preliminary purification, secondary filter is carried out by y-type filter before inflow pneumatic motor, compressed-air actuated cleanliness when ensure that startup, can avoid impurity to enter in unit with pressurized air.
Further, for convenience of maintenance, between described gas holder and pressure regulator valve, stop valve is connected with.
Further, for ensureing start up system safe operation, overpressure damage equipment is prevented, pressure gauge is connected with between described pressure regulator valve and y-type filter, be provided with safety valve between this pressure gauge and y-type filter, described safety valve be provided with AB Air Bleed pipe, this AB Air Bleed pipe is communicated with air.
Further, there is metal-air flexible pipe described y-type filter rear end by Flange joint, this metal-air flexible pipe is communicated with air motor, pressurized air sends into pneumatic motor through metal-air flexible pipe, pneumatic motor can be prevented when running up, the vibrations produced have an impact to start up system, ensure that the stability of comperssed air starting system.
Further, described air compressor is provided with protective housing in its belt pulley side, to form effective isolation, prevents accident.
Beneficial effect: diesel generator comperssed air starting system of the present utility model, ensure that diesel generator startability under cryogenic, simultaneously, compressed-air actuated cleanliness is high, impurity can be avoided to enter in unit, and the stability of a system is good, security of operation.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of diesel generator comperssed air starting system, comprise black starting-up small generation set 1, air compressor 2, oil and water filters 3, gas holder 4, stop valve 5 and pressure regulator valve 6, wherein, black starting-up small generation set 1 is for powering for air compressor 2, oil and water filters 3 is arranged between air compressor 2 and gas holder 4, and be communicated with gas holder 4 with air compressor 2 respectively by pipeline, pressure regulator valve 6 is arranged on gas holder 4 rear end, stop valve 5 is arranged between pressure regulator valve 6 and gas holder 4, and by pipeline communication, pressure regulator valve 6 rear end is provided with y-type filter 10.
Be connected with pressure gauge 7 between pressure regulator valve 6 and y-type filter 10, be provided with safety valve 8 between this pressure gauge 7 and y-type filter 10, described safety valve 8 is provided with AB Air Bleed pipe 9, this AB Air Bleed pipe 9 extends straight up and is communicated with air.
Described y-type filter 10 rear end is provided with metal-air flexible pipe 11, y-type filter 10 two ends are fixed respectively by flange and safety valve 8 rear end pipeline and metal-air flexible pipe 11, and this metal-air flexible pipe 11 rear end is communicated with air motor (not shown).
Be it can also be seen that by Fig. 1, described air compressor 2 is provided with the protective housing 12 of frame structure in its belt pulley side, to cover the rotary component that it exposes.
Working principle of the present utility model is as follows:
First open black starting-up small generation set 1, for air compressor 2 is powered, the pressurized air that air compressor 2 produces is after oil and water filters 3 purifies, be stored in gas holder, due to compressed air pressure higher (about 3Mpa), need to be adjusted to (0.7 ~ 0.8Mpa) in the range of working pressure of pneumatic motor through pressure regulator valve 6, pressurized air is after y-type filter 10 secondary filter, the starter receiver promoting pneumatic motor drives diesel engine flywheel to rotate, to start diesel generator.
