Embodiment
Simultaneously fuel filter seat, fuel filter are exemplarily explained to first embodiment shown in Figure 3, Fig. 4 to second embodiment shown in Figure 5 below in conjunction with Fig. 1.
As shown in Figure 1, fuel filter comprises fuel filter seat 1 and filter core 3.
As shown in Figure 2, fuel filter seat 1 has filler opening 30, and the fuel oil that is not filtered gets into from filler opening 30, and the fuel oil here possibly contain impurity such as iron oxide, dust, moisture.Fuel filter seat 1 also has pump oil suction chamber 32; Pump oil suction chamber 32 is that the counterbore by pipe joint 19, sealing seat 21 and filter cleaner seat 1 limits; Pipe joint 19 has outside thread, and passes through this counterbore that outside thread connects filter cleaner seat 1, and sealing seat 21 is threaded in the inside of pipe joint 19.Mobilizable spherical sealing element 20 is arranged in the pump oil suction chamber 32, and the external diameter of spherical sealing element 20 just seals up sealing seat 21 greater than the orifice diameter of the oilhole 210 of sealing seat 21 when spherical sealing element 20 is seated in the aperture of sealing seat 21.Pipe joint 19 also connects the center of the upper end cap of filter core 3 through its outside thread; Be provided with lip ring 2 between this upper end cap and the filter cleaner seat 1; The filler opening that the fuel oil that gets into from the filler opening of filter cleaner seat 1 30 can pass through the upper end cap of filter core 3 enters into filter core 3; And enter into pump oil suction chamber 32 through sealing seat 21 after the filtering material filtration via filter core 3, and therefore enter into the oil of the fuel oil of pump oil suction chamber 32 for cleaning, can not stop up hand pump 6.The housing bottom of filter core 3 has discharging valve 5 and seal ring 4.
Continuation is with reference to Fig. 2; Fuel filter seat 1 also has pump oil input channel 33; The cross section of pump oil input channel 33 can be circular or square or waist shape or arc or other shapes; No matter which kind of shape pump oil input channel 33 is, defines the spherical parts latus rectum of the diameter of this spherical parts under its situation that can allow that spherical parts passes through for this pump oil input channel.The shape of cross section of pump oil input channel 33 is elongated hole preferably, for example is arcuate socket.One end of pump oil input channel 33 connects pump oil suction chamber 32, one ends and connects oil pumping chamber 34.Spherical sealing element 20 receives that the promotion of oil pressure generally is to be suspended in the pump oil suction chamber 32; Generally can not touch pump oil input channel 33; But preferably the external diameter of spherical sealing element 20 is enough to make it can not pass pump oil input channel 33, also can not be stuck in the pump oil input channel 33, more can not enter into oil pumping chamber 34; Pump oil input channel 33 relative pump oil suction chambers 32 tilt, and 45 degree for example tilt.Fuel filter seat 1 also has the hydraulic fluid port of pumping 31, and oil pumping chamber 34 and pump one-way valve 15 is set between the hydraulic fluid port 31, the conducting direction of one-way valve 15 be like the arrow indicated direction among the figure, leads to from oil pumping chamber 34 and pumps hydraulic fluid port 31.In the embodiment shown in Figure 2, pump oil suction chamber 32 has only an oil circuit to pumping between the hydraulic fluid port 31, the oil circuit that promptly passes through pump oil suction chamber 32, pump oil input channel 33, oil pumping chamber 34 and pump hydraulic fluid port 31 successively.
Hand pump 6 has pump pressure lid 11, pump Returnning spring 12, pump guide holder 13 and pump fastening cover 16; Pump fastening cover 16 is fixedly connected filter cleaner seat 1 through bolt 17; Pump guide holder 13 is by pump fastening cover 16 and filter cleaner seat 1 fixed clamp; Pump pressure lid 11 is enclosed within on the pump guide holder 13 movably; Pump fastening cover 16 provides and pump pressure lid is carried out spacing limited part covers 11 landings to prevent pump pressure, limits oil pumping chamber 32 between pump guide holder 13, pump pressure lid 11 and the filter cleaner seat 1, places pump Returnning springs 12 in the oil pumping chamber 32; One end of pump Returnning spring 12 is against on the pump pressure lid 11 and the other end is against on the filter cleaner seat 1; The outer side wall of pump guide holder 13 is embedded with the U-shaped or the Y shape lip-type seal circle 14 of paired setting, the opening of U-shaped or Y shape lip-type seal circle 14 along pump guide holder 13 axially outwards, U-shaped or Y shape lip-type seal circle 14 seal up the gap between the outer side wall of madial wall and pump guide holder 13 of pump pressure lid 11.Between pump guide holder 13 and the filter cleaner seat 1 seal ring 18 is arranged, to prevent fuel leakage.
As shown in Figures 2 and 3, when hand pump gland 11 was pressed down, oil pumping chamber 34 produced malleation; This moment, one-way valve 15 was opened under the effect of malleation, and spherical sealing element 20 contacts with sealing seat 21 in the bottom; Under the effect of malleation, spherical sealing element 20 and sealing seat 21 compacted sealings; This moment, oil pumping chamber 34 interior gases can only flow to oil outlet 31 from one-way valve 15, were discharged from through the relief opening on the oil outlet 30.When unclamping hand pump gland 11; Under the effect of pump Returnning spring 12, oil pumping chamber 34 produces negative pressure, and this moment is under action of negative pressure; One-way valve 15 closures; Spherical sealing element 20 is picked up, is broken away from sealing seat 21, the interior corresponding suction pump oil pocket 34 of air quilt of fuel oil fitering element this moment, and fuel oil also is inhaled into fuel oil fitering element 3 from filler opening 30 accordingly.Cycling so repeatedly all is full of fuel oil in final fuel oil fitering element 3 and the oil pumping chamber 34.
When engine start, hand oil pump 6 is idle.Fuel oil is inhaled into fuel oil fitering element 3 from filler opening 30, and clean product after filtering gets into pump oil suction chamber 32, gets into oil pumping chamber 34 through pump oil input channel 33 again through ball valve 11, finally gets into oil outlet 31 through one-way valve 15 and gets in the oil-fired system.
Aforesaid embodiment has advantage easy to use; After hand pump and the integrated design of filter cleaner seat, when in the user finds filter cleaner or in the fuel pipe gas being arranged, open the relief opening on fuel filter seat oil outlet top; Push hand pump then, can very easily these gases be discharged.
Aforesaid embodiment also has advantage easy to maintenance.If leakage of oil appears in hand pump, when pushing fault such as motionless, the user can turn on fixing screw, ressembles after the part in the hand pump is cleaned, and can solve fault.
Aforesaid embodiment also has the low advantage of cost of production.Assembling this hand oil pump does not need different equipment, and U-shaped or Y shape lip-type seal circle also are the standard seal parts on the hydraulic pressure, is easy to buying.
Aforesaid embodiment adopts the hand pump of U-shaped or Y shape lip-type seal coil structures; Have and to bear the high advantage of pressure; Through test; Its highest pressure that bears can reach 0.7MPa even higher under the condition of working long hours, and the fuel filter of traditional integrating manual oil pump, its highest pressure that bears is about 0.2MPa under the condition of working long hours.
Aforesaid embodiment adopts a spherical sealing element and a conventional one-way valve, therefore also has the little advantage of flow resistance.If adopt two conventional one-way valves, through test, obviously big many of its resistance.
As: when adopting a spherical sealing with a conventional one-way valve, under flow 300L/h, resistance is 6kPa.
When adopting two conventional one-way valves, under flow 300L/h, resistance is 9kPa.
In like Fig. 4 and embodiment shown in Figure 5, different with first embodiment is, the said counterbore of pipe joint and filter cleaner seat is an one.
