Abstract
The utility model discloses a fuel filer. The fuel filter comprises a fuel coarse filter and a fuel fine filter, the fuel coarse filter and the fuel fine filter are installed on a same fuel filter base, the fuel filter base is provided with a fuel inlet, a fuel duct, a fuel outlet and a plunger type handlance, the fuel duct is communicated with the fuel coarse filter and the fuel fine filter, the plunger type handlance is located in rear of the fuel coarse filter, and a water drain valve is arranged at the bottom of a shell of the fuel coarse filter. Because the fuel coarse filter and the fuel fine filter are integrated, the fuel filter is compact in overall structure and more convenient to install and use; because the number of fuel pipelines is reduced, leakage faults are less likely to happen; because the plunger type handlance is used, the fuel pumping efficiency and the using reliability are improved; after the plunger type handlance is arranged on the fuel coarse filter, fuel entering the handlance can be filtered, and thus the fault rate of the handlance is reduced; water filtered out by the fuel coarse filter can be drained through the water drain valve.
Description
Technical field
The utility model relates to a kind of filter cleaner, relates in particular to a kind of fuel filter using on internal-combustion engine.
Background technique
If there is iron rust in fuel of internal combustion engine, silt, dust, the impurity such as wax crystal and water, the wearing and tearing of the parts such as precision pair of gear pump in fuel pump and oil sprayer will be caused, for the pollutant that fuel of internal combustion engine pump (comprising oil transfer pump and Injection Pump) and oil sprayer are subject to eases down to minimum limit, fuel filter is all installed in fuel of internal combustion engine system, fuel filter fuel preliminary filter and secondary fuel oil filter, there is following defect in fuel filter at present: 1. fuel preliminary filter and secondary fuel oil filter are arranged apart, intermediate demand has independent pipeline to connect, not attractive in appearance on the one hand, increased on the other hand leakage point,
2. fuel oil coarse filter element and fuel oil essence filter core adopt spinning filter core, and outside is metallic case, and inside is paper filter element, and the two connects together and can not be split, and manufacture cost is high, and environment is had to pollution, and user's maintaining cost is high;
3. the hand pump on fuel preliminary filter is diaphragm type, single pump oil mass is few, the negative pressure that elastomer diaphragm easily forms because of fuel flow when engine operation is moved and is caused rupture of diaphragm, in addition, existing hand pump is arranged in before fuel preliminary filter, because some granule foreigns that exist in oil-fired system stick on the one-way valve in hand pump, one-way valve cannot be closed and cause hand pump to lose efficacy.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of reasonable structural arrangement is provided, prevents the fuel filter of leakage of oil.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of fuel filter, comprise fuel preliminary filter and secondary fuel oil filter, described fuel preliminary filter comprises strainer housing and fuel oil coarse filter element, described secondary fuel oil filter comprises secondary filter housing and fuel oil essence filter core, described strainer housing and fuel oil coarse filter element removably connect, described secondary filter housing and fuel oil essence filter core removably connect, described strainer housing and described secondary filter housing are installed on same integral type fuel filter seat, described fuel filter seat is provided with filler opening, oil duct, oil outlet and plunger type hand pump, described filler opening is communicated with fuel preliminary filter, described oil duct is communicated with described fuel preliminary filter and secondary fuel oil filter, described oil outlet is communicated with secondary fuel oil filter, described plunger type hand pump is positioned at the rear of described fuel preliminary filter, the bottom of described strainer housing is provided with discharging valve.
As a kind of improvement, the bottom of described strainer housing is provided with level sensor, and described level sensor is connected with alarm.
As a kind of improvement, the bottom of described strainer housing is also provided with heater.
As a kind of improvement, described fuel oil coarse filter element and fuel oil essence filter core are paper filter element.
Owing to having adopted technique scheme, described strainer housing and fuel oil coarse filter element removably connect, described secondary filter housing and fuel oil essence filter core removably connect, compare the spinning filter core of current use, this structure can be separately renew cartridge more, thereby can reduce costs, by using same fuel filter seat, fuel preliminary filter and secondary fuel oil filter are integrated together, make compact overall structure, improve the convenience of installing and using, fuel preliminary filter and secondary fuel oil filter are communicated with by the oil duct in fuel filter seat, reduced fuel pipe quantity, reduced leakage failure, use plunger type hand pump, because its critical piece is metalwork, therefore reliability is high, and each pump oil mass is large, improved pump oil efficiency, plunger type hand pump is arranged in after fuel preliminary filter, some granule foreigns that can avoid existing in oil-fired system stick on the one-way valve in hand pump one-way valve cannot be closed, reduced the rate of fault of hand pump, the water that fuel preliminary filter can be filtered out by discharging valve emits.
Because the bottom of described strainer housing is provided with level sensor, described level sensor is connected with alarm, can monitor the amount of water accumulation in strainer housing, by level sensor when reaching the water level of appointment, alarm meeting alarm, discharges water thereby can open in time discharging valve.
Because fuel oil essence filter core and fuel oil coarse filter element all adopt paper filter element, recyclable processing, can be to environment, and paper filter element cost is low, has reduced user's cost of use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
