Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1 and Fig. 2, the Novel diesel engine oil pump that the utility model provides, comprise the pump housing 1, pump cover 2 and the fuel filter 3 that screw 4 is fixed together that pass through from top to bottom.The pump housing 1 is up-small and down-big step type hollow circuit cylinder, in the pump housing 1, be provided with transmitting assemblies, transmitting assemblies comprises the transmission shaft 11 that runs through the pump housing 1, is located at the internal rotor 12 of transmission shaft 11 lower ends and can rotates along with internal rotor 12 external rotor 13 of corresponding rotation by pin 15 fixed covers.The length of external rotor 13 and internal rotor 12 is increased to 35mm by original 30mm, thereby has increased the volume of the oil pocket 16 between external rotor 13 and internal rotor 12, and then has increased the oil extraction flow of oil pump.Transmission shaft 11 upper ends are threaded end, and transmission shaft 11 upper ends are stretched out outside the pump housing 1 and are connected to driving gear 14 by pin 15 fixed covers.Pump cover 2 upper ends and the pump housing 1 fit tightly by gasket seal 5, pump cover 2 lower ends are provided with the filler opening 20 of a perforation pump cover 2, on pump cover 2, a side is provided with the oil outlet 21 stretched out, on pump cover 2, a side also is provided with the safety pressure unloading port 22 of stretching out vertical with oil outlet 21, filler opening 20, oil outlet 21, safety pressure unloading port 22 all with external rotor 13 and internal rotor 12 between oil pocket 16 be communicated with.Fuel filter 3 is installed in pump cover 2 lower end filler opening 20 places sealings, fuel filter 3 comprises the fuel filter pipeline 31 that tilts to stretch out and the oil suction dish 32 that is placed in the bowl structure of fuel filter pipeline 31 front ends, oil suction dish 32 front edges draw in to center and form a circle groove, in groove, be provided with circular filter screen 33, filter screen 33 rear ends are fixing by cross 34 thereafter.Fuel filter 3 plays the effect of filtering the solid impurity in machine oil, thereby prevents that oil pump is contaminated, by gasket seal 5, seals between fuel filter 3 and pump cover 2.
Referring to Fig. 3, in safety pressure unloading port 22, be provided with safety installations, safety installations comprises steel ball 23, limiting valve spring 24, spring housing 25, pad 26 from inside to outside and sells 27, and the thickness adjustable safety pressure unloading port 22 by regulating pad 26 goes out oil pressure.
During use, driving gear 14 and the gear shaft gear on diesel engine are meshed, by gear shaft gear driven driving gear 14, rotate, thereby drive transmission shaft 11 and internal rotor 12 rotations, internal rotor 12 drives external rotor 13 and does corresponding rotation, oil pocket 16 between internal rotor 12 and external rotor 13 constantly forms high-voltage oil cavity and low pressure oil pocket, machine oil sucks from the oil suction dish 32 of fuel filter 3 front ends, by fuel filter pipeline 31, enter the filler opening 20 on pump cover 2, in low pressure oil pocket by filler opening 20 inhalation machine oil pumps, running by inner and outer rotors, thereby the low pressure oil pocket becomes high-voltage oil cavity produces pressure, by oil outlet 21, discharge again, oil outlet 21 is connected with the machine oil pipeline in diesel engine, by the machine oil pipeline by oil delivery in the oil leab in diesel engine, thereby play the purpose of lubricated parts and components of diesel engine.And the safety installations in the safety pressure unloading port 22 of pump cover 2 one sides plays safety effect; when the pressure of the inner machine oil of oil pump is excessive; thereby the steel ball 23 in safety pressure unloading port 22 just can compress limiting valve spring 24 this safety pressure unloading port 22 is opened; machine oil just can be from flowing out the safety pressure unloading port 22 on pump cover 2; reduce the chamber pressure of oil pump, thereby oil pump itself is played a protective role.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
