Abstract
The utility model relates to a filter assembly unit, in particular to a filter assembly with a hand pump, which mainly solves the technical problems that the fuel oil is hard to enter the filter and the oil cannot be pumped since the check valve position of the existing filter assembly with the hand pump is adhered by impurities. The technical scheme adopted is that the filter assembly with the hand pump is connected in series with a fuel filter through a base with hand pump and is characterized in that the oil inlet of the hand pump is directly connected with the filter; and the oil outlet end of the port is connected with the check valve. The utility model can realize manual oil pumping, and achieve the aims of emptying the pipe air and transferring the fuel oil.
Description
Technical field:
The utility model relates to a kind of filter assembly device, and particularly a kind of band hand pump filter assembly can be realized hand pump oil, reaches emptying pipeline air, carries the purpose of fuel oil.
Background technique:
At present, use the filter assembly product of the band hand pump on commercial car to connect to form on the market by band hand pump base and fuel filter, as shown in Figure 1, be band hand pump base 1 and fuel filter serial connection, hand pump filler opening 4 is according to fuel direct, and fuel oil is earlier through the one-way valve 3 in the hand pump of base, after clear after filtration device filter, arrive center oil outlet 6 through interface 5, and then enter oil-fired system.But because domestic fuel oil quality differs and the user uses fuel oil that certain randomness is arranged, cause in the fuel oil fuel tank, occurring unpredictable big fuel particles impurity, when fuel flow, granule foreign can be attached on the band hand pump base in one-way valve 3 on, cause the base hand pump to lose efficacy, can't pump oil, cause whole assembly product failure easily.
The model utility content:
The purpose of this utility model provides a kind of band hand pump filter assembly, and the one-way valve place that mainly solves the filter assembly of existing band hand pump causes fuel oil to enter the filter cleaner difficulty because impurity adheres to, technical problem that can't pump oil.
The technological scheme that its technical problem that solves the utility model adopts is: band hand pump filter assembly, and by band hand pump base and fuel filter serial connection, it is characterized in that: the hand pump filler opening directly connects filter cleaner, and the interface oil outlet end connects one-way valve.
The beneficial effects of the utility model are, can in user's using process, need not too much to consider of the influence of the granule foreign of fuel oil, when hand pump work, avoid in the fuel oil impurity being with the harm of hand pump filter assembly to band hand pump filter assembly, simple in structure, convenient and practical.
Description of drawings:
Fig. 1 is existing band hand pump understructure schematic representation
Fig. 2 is the utility model general assembly drawing
Fig. 3 is the utility model band hand pump understructure schematic representation
Among the figure: 1-band hand pump base, 2-filter cleaner, 3-one-way valve, 4-hand pump filler opening, 5-interface, 6-center oil outlet
Embodiment:
With reference to Fig. 2,3, band hand pump filter assembly, by band hand pump base 1 and fuel filter 2 serial connections, hand pump filler opening 4 directly connects filter cleaner 2, and interface 5 oil outlet ends connect one-way valve 3, and described one-way valve 3 is a diaphragm type one-way valve.Fuel filter 2 is positioned at front end, and band hand pump base 1 is positioned at the rear end, uses intermediate fuel oil earlier by fuel filter 2, passes through hand pump internal check valve 3 again.When the priming pump of craft or motor is worked, fuel oil is filtered by high-precision fuel filter 2 earlier, and granule foreign is separated by the filter cleaner medium with moisture, and clean fuel oil continues to flow, arrive one-way valve 3 places of assembly hand pump, enter center oil outlet 6 then.Make one-way valve 3 avoid the chance that directly contacts with the fuel oil that pollutes, thereby greatly reduce the problem that band hand pump filter assembly lost efficacy.
Claims (2)
