Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of fuel pump, it can prevent fluid from entering between float and connecting rod, makes the measuring accuracy of oil level high, thus ensures the reliable working performance of fuel pump.
The technical solution of the utility model: a kind of fuel pump, include upper cover, the pump housing, oil inlet pipe, oil outlet tube, described oil inlet pipe one end is plugged in and covers, the other end extends in the pump housing, described oil outlet tube one end is plugged in and covers, the other end also extends in the pump housing, the fuel level sensor for detecting Height of oil is provided with in the described pump housing, fuel level sensor includes sensor body, the connecting rod be connected with sensor body, float, float is provided with the through hole passed for connecting rod, connecting rod is located in through hole, it is characterized in that: the two ends of described through hole are all inserted with elastic seal cartridge, described elastic seal cartridge is set on connecting rod, described float two ends are respectively equipped with inner position seat, outside fix seat, inner position seat, outside fix seat is fixedly connected with connecting rod.
Adopt technique scheme, the elastic seal cartridge of setting, can prevent fluid from entering between float and connecting rod well, make the measuring accuracy of oil level high, thus ensures the reliable working performance of fuel pump; The inner position seat arranged, outside fix seat can prevent float from producing position skew.
Further setting of the present utility model: described inner position seat, outside fix seat are all extended with annular boss in through hole, and described annular boss is pressed on elastic packing and puts.
Adopt above-mentioned further setting, elastic seal cartridge can be extruded by annular boss, stuffing box gland is produced and expands, thus make better tightness between stuffing box gland and connecting rod, through-hole wall.
Setting further more of the present utility model: the tapered setting of described elastic seal cartridge, the big opening end of elastic seal cartridge is arranged outward towards through hole.
Adopt and above-mentionedly to arrange further again, this elastic seal cartridge set-up mode, when being extruded by annular boss, it more easily produces expansion, and its sealing effect is better.
Of the present utility modelly further to arrange again: described inner position seat, between outside fix seat and the both ends of the surface of float, be provided with seal ring.
Adopt and above-mentionedly further to arrange again, the seal ring of setting, can prevent fluid from inner position seat, enter in float between outside fix seat and the both ends of the surface of float, better tightness.
Further setting more of the present utility model: described outside fix seat and connecting rod screw-thread fit, inner position seat and connecting rod are wholely set.
Adopt and above-mentionedly further to arrange again, inner position seat and connecting rod are wholely set, and can facilitate the processing of inner position seat, and, when installing float, only need float to be enclosed within connecting rod, then rotate outside fix seat and float can be fixed, install easily.
