Along with the fast development of China railways traffic, the power of locomotive engine is increasing, and every indexs such as the efficient of motor, life-span have been had higher requirement.The fuel delivery pumping system is the important component part of locomotive engine, is bearing the task of carrying fuel oil.So the performance of fuel delivery pumping system is most important to the reliability that ensures locomotive engine and even whole locomotive.
The fuel delivery pumping system generally is to be become by oil hydraulic pump, motor, three groups of subsystems of electric machine control system, is the critical component of motor, directly affects power performance, fuel combustion efficient, toxic emission level and other multinomial important indicator of locomotive.
Oil hydraulic pump, motor and the electric machine control system of existing fuel transfer pump are relatively independent, so the fuel delivery pump volume is big, motor and automatically controlled components and parts can not well be cooled off, cause the flow of fuel transfer pump little, outlet pressure is low, motor and the heating of automatically controlled components and parts, working life is short, inefficiency.
Generally, the temperature of motor will be higher than the temperature at other position in the locomotive, influenced by it, and fuel transfer pump also can have higher temperature, and this can have a strong impact on the use of pump, shortens the life-span of pump.Use and the situation of keeping in repair from reality, the probability that fuel transfer pump breaks down is higher than other component, and engine power is big more, and the probability that fuel transfer pump breaks down is high more.
Therefore, press for the novel fuel drug delivery pump system and substitute existing fuel delivery pumping system, thereby realization reduces the temperature of fuel transfer pump, particularly reduces motor temperature, improve the engine operation reliability, prolong the motor purpose in working life.
Summary of the invention
Goal of the invention of the present invention: the temperature that realizes reducing fuel transfer pump, particularly reduce motor temperature, improve the engine operation reliability, prolong motor working life, be specifically under the prerequisite that does not increase any extra cooling unit, motor and control system to fuel transfer pump are cooled off, and the whole volume and weight that reduces the fuel delivery pumping system, improve the service behaviour of fuel delivery pumping system.
The present invention adopts following technological scheme to realize:
A kind of fuel delivery pumping system that has refrigerating function, comprise oil hydraulic pump, motor, control system and oil circuit, motor comprises motor shaft, motor coil, motor stator, control system comprises the Electric Machine Control plate, it is characterized in that oil hydraulic pump, motor, control system and oil circuit become one, oil hydraulic pump comprises the pump housing that is placed in the spill outside the motor stator, pump housing upper end connects the Electric Machine Control plate, the top and bottom of the pump housing are processed with circular groove respectively, upper end circular groove and lower end circular groove are communicated with, the lower end circular groove is provided with filler opening and oil outlet, the center portion surrounded in Electric Machine Control backboard portion and pump housing upper end and with space that the upper end circular groove is communicated with in intermeshing driving gear and driven gear are set, the rotating shaft of driving gear connects motor shaft, the rotating shaft of driving gear and driven gear is connected the Electric Machine Control plate respectively, and the lower end of the pump housing is provided with end cap.
Another preferred version of the present invention: upper end circular groove and lower end circular groove all comprise left side circular groove and right side circular groove, be communicated with by some honeycomb ducts between the left side circular groove of top and bottom, also be communicated with between the right side circular groove of top and bottom by some honeycomb ducts, the right side circular groove of lower end connects filler opening, the left side circular groove connects oil outlet, the left and right circular groove of upper end links to each other through the driving gear and the driven gear of gear pump, and the left and right circular groove of lower end does not directly link to each other.
Beneficial effect of the present invention: oil hydraulic pump, motor, control system, oil circuit etc. are carried out organic integration, and designed deflector, promptly on the pump housing, process circular groove, honeycomb duct, make fuel oil the flow through outside of motor stator and the back of control system, the low temperature fuel oil can be taken away the heat that motor produces, thereby realizes the cooling to motor and control system.Simultaneously, the low temperature fuel oil flows to motor again after preheating, can improve the combustion performance of fuel oil, thereby improves the service behaviour of motor.
