School pumps, the school is the meaning of correction and repair. The task of a light and compact fuel pump is to provide an oil pump with a housing made of an aluminum-containing material and a movable mold part arranged in the housing, The movable molding being at least partially made of a sinterable material comprising an iron-based alloy containing at least one austenite, and wherein the molded part made of a sinterable material has a A thermal expansion coefficient of at least 60% of the thermal expansion coefficient of the housing. What is the school pump? 1. School oil pump, suitable for conveying all kinds of oil, such as heavy oil, diesel oil, lubricating oil, with copper gear can deliver low flash point liquid, such as gasoline, benzene, the unit also produces stainless steel gear pump can convey drinks and corrosion Sexual fluid. 2. The school oil pump, at the same time can be applied to hard particles or fibers, suitable for a variety of viscosity. The temperature can be as high as 300 ℃, if you need to transport high temperature liquid, please use the high temperature resistant gear pump to transport the liquid under 300 ℃. 3. School oil pump, a variety of pump-type structure is simple and compact, easy to use and maintain, with good self-suction, to help each pump without filling the liquid before. 4. Some pump lubrication is delivered by the liquid automatically reached, so the daily work without additional lubrication. 5. School oil pump using flexible coupling power transmission can compensate for the pump caused by installation of small deviations. In the pump work by the inevitable hydraulic impact, can play a better buffering effect. The above is the school oil pump related concepts.
