The stainless steel gear pump has adopted the necessary structure and function in the design, so you must respect the necessary use methods and principles in the occupation, so that you can use it to the best effect. Of course, you need to pay attention to some things in the process of use. The whole is as follows: SS gear pump assembly position: There are two main types of assembly positions for stainless steel pumps, which can be assembled in the fuel supply pipeline and assembled in the gasoline tank.
However, the use of the latter is outstanding and common. Electric gasoline pumps are usually suspended vertically in the fuel tank with a fuel pump bracket that does not change on the fuel tank. Two-stage stainless steel gear pumps need to pay attention to some things and tricks in the use. In view of the extremely volatile gasoline, add When the pump is working, the temperature rises and a one-sided vacuum is formed when the oil is sucked, which causes the vaporization of gasoline and the reduction of the pump oil volume, which causes the input oil pressure to shake.
In contemporary automobiles, two-stage electric gasoline pumps are commonly used, and the two electric gasoline pumps can be connected to improve the fuel supply talent. When the oil pipeline is blocked or the gasoline filter is blocked, the gasoline pressure exceeds the specified value, and the pressure limiting valve Turn it over, and the gasoline flows back to the oil inlet side. After the engine is turned off, the one-way valve is closed to prevent the gasoline in the oil pipeline from flowing back, and there is still the necessary residual pressure in the oil circuit to facilitate the engine restart.
Stainless steel gear pump composition: The stainless steel pump is mainly composed of a pump body, a permanent magnet DC motor and a shell. In addition, it is also equipped with a safety valve and a one-way valve. The safety valve is also called a pressure limiting valve (or overflow valve). ), which is mainly composed of valve seats, sealing steel balls and springs. The one-way valve is assembled at the oil outlet of the stainless steel gear pump. The pump body is the main body of the electric gasoline pump. According to the difference in its structure, it can be divided into: roller Type, turbine type, gear type, etc.
