Technical field
The utility model relates to a kind of diesel engine fuel-firing hand pump, especially refers to the plunger type fuel oil hand pump in the diesel engine.
Background technique
In the oil for diesel engine fuel system, the diesel oil of fuel tank is extracted out through oil transfer pump, be transported to high pressure oil pump with certain pressure and flow through the filter cleaner filtration, high pressure oil pump nebulizes fuel injection at regular time and quantity with higher pressure, spray in the diesel engine cylinder, produce power with the air mixing burning, promote engine running.
Because the diesel engine high pressure oil pump is a plunger type, fuel tank is apart from the engine oil pipe range, resistance is big, there is air in the pipeline, during engine start, oil transfer pump can not arrive the high pressure oil pump front end with fuel delivery within a short period of time, also just can not guarantee the necessary pressure diesel oil of high pressure oil pump, cause starting difficulty, even fail to start.Usually, on the oil-fired system oil transfer pump, utilize inner two the single-phase safety check of oil transfer pump, hand pump is connected on the oil transfer pump,, makes to be full of fuel oil in the oil-fired system with hand pressing hand pump, exhausting air, guarantee the motor normal starting, hand pump can also be formed independent parts with two single-phase safety check, and serial or parallel connection is in diesel fuel system, air in its system is discharged, so hand pump uses comparatively extensive in diesel engine.
At present, a kind of existing hand pump, as shown in Figure 1, must unscrew handle 1 earlier in use, connect core bar 5, between handle 1 and hand pump body 4, Returnning spring 3 is set again with its pin 2, this Returnning spring 3 will move on the piston 6 by core bar 5, and after use, must tighten handle 1, and make and start the function normal starting, obviously operate cumbersome.
Another kind of existing hand pump, as shown in Figure 2, it is by hand pump body 1, outer spring 2, outer spring seat 3, valve block 4, inner spring 5, lip seal circle 6, only enclose 7, following 8 of hand pump, clip 9 and inner spring seat 10 constitute; Though avoid operating the forward and backward trouble that will unscrew respectively, tighten handle, because hand pump body 1 is to be become one with hot pressing by ectosome and push rod, poor impact resistance, also easily aging, distortion are so working life is short; In addition, in hand pump body 1 lower end is conical surface hook groove, place and only enclose 7 and be resisted against on the inverted cone surface of following 8 of hand pump, under the effect of outer spring 2 and the distortion of hand pump 1 and following 8 (metal manufacturing) collision of hand pump, easily make and only enclose 7 and get loose, produce the use inefficacy.
Summary of the invention
The purpose of this utility model provides a kind of diesel engine fuel-firing hand pump, the hand pump body of push rod and ectosome split composition, on the following outer cylinder of hand pump, overlap a matrix spring seat admittedly, outer spring is arranged between following of this hand pump body and the hand pump, and inner spring is arranged in the endoporus of following of hand pump, also embed embedded piece, be embedded in one at ectosome lower end dovetail groove again and end circle in following upper end of hand pump.
The utility model provides a kind of diesel engine fuel-firing hand pump, by the hand pump body, outer spring, the outer spring seat, valve block, inner spring, the lip seal circle, end circle, following of hand pump, clip and inner spring seat constitute, wherein the hand pump body is nested with versatilely outside the following outer rim of hand pump, outer spring is arranged between following of this hand pump body and the hand pump, and inner spring is arranged in the endoporus of following of hand pump, the hand pump body is made up of push rod and ectosome split, outer spring is arranged between the push rod and following outer outer spring seat of hand pump of this hand pump body, this ectosome lower end dovetail groove is embedded in the above-mentioned circle that ends, and this only encloses internal surface and go up on corresponding cylndrical surface and the end face thereof against following of hand pump respectively a part of upper-end surface, also embeds the embedded piece of a matrix in the inside groove of following upper end of hand pump.
The utility model provides a kind of diesel engine fuel-firing hand pump, should end the trapezoidal circle that circle is made for nylon.
The utility model provides a kind of diesel engine fuel-firing hand pump, and this embedded piece is the round metal packing ring.
The utility model provides a kind of diesel engine fuel-firing hand pump, and this ectosome is a metallic stamping pieces.
The utility model not only the hand pump manufacturing simple, easy to process, reduce cost and good airproof performance, and safe and reliable to operation greatly.

A kind of embodiment's of Fig. 3 the utility model sectional view.
Embodiment
A kind of embodiment is by hand pump body 1, outer spring 2, outer spring seat 3, valve block 4, inner spring 5, lip seal circle 6, only enclose 7, following 8 of hand pump, clip 9, inner spring seat 10 and embedded piece 13 constitute; As shown in Figure 3, wherein:
Hand pump body 1 is made up of push rod 11 and ectosome 12 splits, this hand pump body 1 is nested with versatilely in following 8 peripheries of hand pump, wherein ectosome 12 is by the moulding of metal cold-rolling steel-plate punch, and through sandblast blackout or plastic-blasting processing, both guaranteed the impact resistance height, and can as the ectosome of plastics, not have defective such as easily aging, distortion, therefore, prolong working life, and these ectosome 12 lower ends also offer dovetail groove 121; Push rod 11 makes these push rod 11 end faces be resisted against the interior top of ectosome 12 for being arranged on the plastics T type bar in the ectosome 12.
Also overlap lip seal circle 6 admittedly on following 8 outer cylinder of hand pump, and be provided with inner spring seat 10 in following 8 endoporus lower end of this hand pump, the shoulder of a clip 9 is supported and against inner spring seat 10 upper-end surfaces in these inner spring 5 lower ends, and a valve block 4 lower end surfaces are supported in these inner spring 5 upper ends, when inner spring 5 relaxes, these valve block 4 upper-end surfaces are against push rod 11 lower ends, and when inner spring 5 compressions, these valve block 4 upper-end surfaces abut to the level and smooth bottom surface of embedded piece 13, to guarantee higher sealing, this embedded piece 13 is the round metal packing rings that embed in following 8 upper end inside groove of hand pump, because this embedded piece 13 is simple in structure, be convenient to the grinding high precision plane, and avoided the difficulty of following 8 upper end grinding internal surfaces of hand pump.
Only enclose the 7 ladder type circles of making for nylon, it embeds in the ladder-type trough 121 of ectosome 12 lower ends and is embedded on the ectosome 12, and this only encloses 7 internal surface and a part of upper-end surface and is resisted against on following 8 of the hand pump on corresponding cylndrical surface and the end face thereof, in case ejecting under outer spring 2 effects, hand pump body 1 lost efficacy, so, can guarantee hand pump body 1 metalwork directly and following 8 metalworks of hand pump rub and deface mutually.
Operation of the present utility model and working principle:
Directly with the ectosome 12 of hand pressing hand pump body 1, hand pump body 1 moves down when using, and this hand pump body 1 reduces with the cavity volume that lip seal circle 6 is formed, and the push rod 11 of hand pump body 1 backs down valve block 4, with air or fuel oil extrusion;
When unclamping hand, move on the hand pump body 1, hand pump body 1 cavity volume increases, air or fuel oil are entered in the inner chamber of hand pump body 1, until valve block 4 upper-end surfaces till embedded piece 13 lower end surfaces, prepare for pressing hand pump body 1 again, constantly repeat above pressing hand pump body 1, just constantly fuel oil is charged into oil-piping, reach the air in the emptying pipeline, and behind the operator press pump 1, valve block 4 is under inner spring 5 effects, automatically block the suction port of following 8 lower ends of hand pump, just stop air to enter in the oil-piping, thereby guarantee motor normal starting within a short period of time and operation.
