Classification
Gasoline pump driven by the different ways, can be divided into mechanical drive diaphragm and electric drive two.
Diaphragm type petrol pump
Membrane petrol pump is a representative of the mechanical petrol pump, used for carburetor engine, generally rely on the camshaft on the eccentric wheel drive, its work is:
① suction camshaft rotation, when the eccentric wheel top drive rocker, pull down the pump rod, the pump down, resulting in suction, the gasoline will be sucked out from the tank, and through the tubing, gasoline filter, into the petrol pump oil room.
② pump oil When the eccentric wheel through a certain angle is no longer the top of the rocker, the pump membrane spring stretch, the top of the pump membrane rise, the gasoline from the oil valve to the carburetor chamber.
The diaphragm petrol pump is characterized by a simple structure, but due to the thermal effects of the engine, special attention should be paid to ensuring the performance of the pump oil at high temperatures, as well as the durability of the rubber material diaphragm for heat and oil.
General gasoline pump maximum fuel consumption than gasoline engine maximum fuel consumption of 2.5 to 3.5 times. When the pump oil is greater than the fuel consumption and the carburetor float chamber needle valve is closed, the oil pump in the oil pipeline pressure increases, the reaction to the pump, the diaphragm stroke to shorten or stop working.
Electric petrol pump
Electric petrol pump, do not rely on camshaft drive, and rely on electromagnetic force repeatedly suction pump film. This electric pump, free to choose the installation location, and to prevent air resistance phenomenon.
The main mounting type of the electric petrol pump for the gasoline jet engine is either installed in the oil supply line or in the fuel tank. The former layout of a larger range, do not need to specifically design gasoline tank, easy installation and disassembly. But the oil pump oil absorption section is long, easy to produce air resistance, work noise is also large, in addition to the oil pump must not be disclosed, the current new vehicles have been less use of this type. The latter fuel pipeline is simple, low noise, more fuel leakage is not high, is the main trend.
At work, the petrol pump flow in addition to providing the necessary operation of the engine consumption, but also to ensure adequate return oil flow to ensure that the fuel system pressure and adequate cooling.
