Abstract
The utility model discloses a diesel engine fuel supply system for an emergency power station, which comprises a fuel tank. An outlet of the fuel tank is successively connected with a fuel coarse strainer, a fuel delivery pump, a first one-way valve and a fuel fine filter, an outlet of the fuel fine filter is connected with an inlet of a fuel mechanism of a diesel engine, the fuel tank is arranged above the fuel mechanism of the diesel engine, a bypass is disposed between the fuel coarse strainer and an inlet of the fuel fine filter, and a second one-way valve is arranged on the bypass. The diesel engine can also be started when in emergency conditions of power failure, as the installation position of the fuel tank is higher, fuel in the fuel tank can directly enter the fine filter under the action of gravity through the coarse strainer and the bypass via the second one-way valve and then is supplied to the fuel mechanism, so that the diesel engine can be started, after the diesel engine is started, a generator of the diesel engine can generate power which is supplied to a motor of the delivery pump to support running of the motor, and the fuel delivery pump can operate normally. Therefore, the diesel engine can be normally started when in the emergency state of power failure.
Description
Technical field
The utility model relates to a kind of fuel oil supply system, particularly a kind of emergency power station diesel engine fuel oil supply system.
Background technique
Existing emergency power station diesel engine fuel oil supply system comprises and draws together fuel tank that the outlet of fuel tank is Bunker of Redelivery strainer, fuel transfer pump, first one-way valve, secondary fuel oil filter successively, and the inlet of the fuel oil mechanism of the outlet of secondary fuel oil filter and diesel engine joins.During work, fuel transfer pump moves through driven by motor, and fuel from fuel tank is inhaled into transfer pump through strainer, is discharged by the exhaust port of transfer pump and enters secondary filter through first one-way valve, enters the fuel oil mechanism of diesel engine again by the fuel oil of secondary filter.The shortcoming of the fuel oil supply system of this structure is that fuel transfer pump can't be worked under the state that has a power failure, and causes diesel engine not start.
Summary of the invention
The purpose of this utility model provides a kind of emergency power station diesel engine fuel oil supply system that diesel engine can normally start under the emergency condition that has a power failure, and overcomes the deficiencies in the prior art.
Emergency power station of the present utility model diesel engine fuel oil supply system, comprise fuel tank, the outlet of fuel tank is Bunker of Redelivery strainer, fuel transfer pump, first one-way valve, secondary fuel oil filter successively, the inlet of the fuel oil mechanism of the outlet of secondary fuel oil filter and diesel engine joins, it is characterized in that: described fuel tank is located at the top of the fuel oil mechanism of described diesel engine, be provided with bypass between the inlet of described fuel preliminary filter and secondary fuel oil filter, and in bypass, be provided with second one-way valve.
Emergency power station of the present utility model diesel engine fuel oil supply system, case of emergency as power failure, also can start diesel engine, this is because the mounting point of fuel tank is higher, fuel oil in it can directly enter secondary filter by strainer and bypass through second one-way valve under the effect of gravity, to fuel oil mechanism fuel feeding, reach the purpose of diesel engine starting, the motor operation that the generator that starts the back diesel engine can generate electricity and supply with transfer pump, make the fuel transfer pump proper functioning, so the utility model can normally start diesel engine under the emergency condition that has a power failure.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 1 is fuel tank, and the outlet of fuel tank 1 is joined with strainer 2, fuel transfer pump 3, first one-way valve 5, secondary fuel oil filter 6 successively, and the filler opening of the fuel oil mechanism 7 of the outlet of secondary fuel oil filter 6 and diesel engine joins.Can fuel tank 1 be arranged on eminence by supporting frame during installation, promptly be higher than the fuel oil mechanism 7 of diesel engine, preferably fuel tank 1 is located at more than the filler opening of fuel oil mechanism 7 of diesel engine at least 2 meters position.Between the inlet of the outlet of strainer 2 and secondary filter 6, be provided with bypass, and in this bypass, add second one-way valve 4.
