Many people believe that the electric oil pump installed on the bracket relies on soaking in gasoline to cool it. After disassembling the heat transfer oil pump, the aluminum casing on the outside of the pump was opened and the oil pump was naturally divided into several large pieces. The cast steel housing was actually designed to hold these parts together and maintain them as a whole. The decomposed hot oil pump is divided into the following parts: The thermal oil pump is mainly composed of a pump body, a rotor, a bearing seal and the like, adopts a high-temperature-resistant packing seal structure, and has an additional temperature-resistant oil seal to function as an auxiliary seal. The pump and motor are connected using a three-jaw coupling.
In the lateral direction of the pump, the first one to be seen is the nozzle. The nozzle is provided with a nozzle and oil return one-way valve for connecting the oil pipe, and includes a bleeder valve for fuel pressure relief (spring-loaded Valve, similar in structure to vacuum fuel pressure regulator).
Look down the pump nozzle and see the inlet. The inlet is at the bottom of the pump. It is connected with the oil outlet by the aluminum shell, contains the above-mentioned pieces, and is connected with an interface that can be connected with the filter. If this structure uses immersion heat dissipation, then thick engineering plastics and rotors can not touch the outer wall, enough to make the oil pump burned out. In fact, when the oil pump is working, the rotor part is used to dissipate heat through the gasoline flowing through the rotor. In other words, as long as the oil pump can pump oil, there is no problem of heat dissipation. For some oil pumps, whether the oil return path is unimpeded is related to the life of the oil pump and the poor oil return path will cause the oil pump to work under high pressure for a long time and increase the load on the oil pump. The characteristics of the DC motor tell us that when the load is large and low, The current flowing through the rotor will increase sharply, and at this time, because the fuel flow rate drops, the heat dissipation effect is not good. For electronic oil pumps, it is worse. So, instead of superstitiously saying about 1/4 box, as long as your car can continue to supply oil, then you will not burn the oil pump. If you can't continuously supply oil and the car is breathing, you must be extremely careful. And do a good job of preparing the oil pump at any time.
The motor part of the oil pump occupies an important position. The standard DC motor structure, except that the bearing caps at both ends are replaced by the other two sides of the oil pump, and has a self-compensating carbon brush length similar to that of a generator carbon brush. The stator of the permanent magnet is affixed to the interior of the engineering plastic. The outer shell of the motor, the enameled wire coated by a special material is the most easily burned part in the rotor (or the oil pump).
