Electronic pump working principle: is the circular motion of the motor, through the mechanical device so that the diaphragm inside the pump do reciprocating motion, so as to compress and stretch the pump cavity (fixed volume) in the air, under the action of the one-way valve, the formation of positive pressure at the outlet. Vacuum is formed at the pumping mouth, resulting in a pressure difference with the outside atmosphere. Under the action of pressure difference, the water pressure is put into the inlet and then discharged from the drain. Under the action of the kinetic energy transferred by the motor, the water continues to be inhaled and discharged, forming a stable flow rate.

The main function of the working principle of the electronic water pump is to force cooling of the oil at the turboshaft after flameout. Turbine work turboshaft external lubrication and cooling system is photocleavable, due to the oil inlet than oil outlet, so the oil pressure in the turbine shaft and shell under the action of established between oil film is used for lubrication turboshaft, and take away a part of the turbine heat, oil heat away eventually escaping through the oil pan and oil cooler); The outside of the turbine shell that is in contact with the oil is wrapped with cooling water. Also, because the inlet is much larger than the outlet, there is a certain pressure in the cooling water between the shells, but the pressure is mainly to ensure that the cooling water keeps good contact with the shell and ensures sufficient cooling effect.

Cooling vortex reason: due to the rotation of the turbine blade is depend on the emissions of the engine working after impact, in addition to the quantity of heat of exhaust gas, waste gas in the process of the impact of the turbine blade part of the kinetic energy will be transformed into heat energy, thus turbine becomes very hot (extreme cases can be more than 700 ℃, at this time of turbine brick red, like a red-hot coal.

Under normal circumstances, if you have just finished running on the highway, pull into the dark immediately, you can see that the turbine is reddish.) , if cannot receive timely cooling turboshaft, thin oil will be due to the high temperature are abnormal, unable to build enough lubrication oil film to ensure turbine shaft, and due to the effect of high temperature, engine oil to the oxidation (after the serious deterioration of the oil as it is in hands of melted chocolate), resulting in the engine lubrication system vicious consequences of failure.
