Stainless steel gear pump from the shell, cylindrical roller and rotor and other components. Five rollers in the rotor slot radial slide, the rotor and the housing there is a certain eccentricity. Rotor in the DC motor driven by the rotation, under the action of centrifugal force, the roller pressed against the inner surface of the pump body to form five relatively independent sealed chamber. Rotation, the volume of each sealed chamber constantly changing, in the inlet, the volume increases, the formation of a certain vacuum, will be filtered into the pump of gasoline. At the oil outlet, the volume becomes smaller and the pressure rises, the gasoline passes through the DC motor and opens the one-way valve. Stainless steel gear pump in the specific use of an important performance, in the design of a certain structure and performance, in accordance with certain methods of use and the principle of work and use of liquid transport can play a good advantage of features and performance, Here to introduce the structure and performance of stainless steel gear pump installation operation in use should pay attention to matters: 1, composition: stainless steel pump is mainly composed of pump, permanent magnet DC motor and the shell of three parts. Also equipped with safety valve and check valve. Safety valve, also known as pressure limiting valve (or relief valve), is mainly composed of a valve seat, sealed steel ball and spring. Check valve installed in the stainless steel gear pump outlet. Pump body is the main electric gasoline pump, according to the different structures can be divided into: roller, turbo, gear and so on. 2, the installation location: There are two main stainless steel pump installation location, that is installed in the fuel supply pipeline and installed in the fuel tank. However, the latter is widely used. The electric gasoline pump is usually suspended vertically in the fuel tank by a fuel pump bracket fixed on the fuel tank. Two-stage stainless steel gear pump need to pay attention to some issues and methods of use, due to the highly volatile gasoline, coupled with the pump when the temperature rise and suction when the local vacuum, so that the vaporization of gasoline, pump oil reduction, leading to output pressure fluctuation. Hyundai Motor in the widely used two-stage electric gasoline pump, that is, two electric gasoline pumps in series, so that oil supply capacity. When the pipeline is blocked or the fuel filter is clogged, the pressure of the gasoline exceeds the specified value, the pressure limiting valve opens and the gasoline flows back into the oil side. After the engine is turned off, the one-way valve is closed to prevent the reverse flow of gasoline in the oil pipeline and to maintain a certain residual pressure in the oil pipeline so as to restart the engine. 3, the role of stainless steel gear pump: the gas sucked out of the tank, the fuel supply system to provide sufficient pressure of gasoline. Electronic gasoline injection system pressure is generally: multi-point injection: 0.25 ~ 0.35Mpa; single point injection: 0.1Mpa. Turbine stainless steel gear pump mainly by the turbine, shell and pump cover and other components. Turbine driven by the motor, the role of centrifugal force, the turbine close to the shell, the gasoline through a narrow gap from the oil side of the drive to the oil side and thus pressurized, the fuel through the motor to play the role of internal cooling motor.
Galvanized Roller Shutter Door
Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.
Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.
