Hydraulic piston pump additional features completed by the safety valve and check valve

Hydraulic piston pump additional features completed by the safety valve and check valve. When the pressure relief valve to avoid excessive increases fuel line blockage, caused by pipeline rupture or hydraulic piston pump damage occurred. The purpose of the one-way valve is set, when the fuel pump to stop working in the oil seal, so that the fuel system to maintain a certain residual pressure to the engine easier to start the next. Hydraulic piston pump is the main pump oil can be divided according electric petrol pump to their different structures and flat roller blade. The most common roller hydraulic piston pump. Hydraulic piston pump is installed in the vehicle fuel tank mounted on the outside and the fuel tank outside. There are a few models in the fuel tank, outside of the installation of an hydraulic piston pump, both series in oil on the road.In modern cars used in a variety of fuel injection system, fuel supply means they are different, but must be safe with an hydraulic piston pump. Its main task is to supply enough fuel system and there is a certain pressure fuel. Due to the mechanical petrol dispenser pump diaphragm by structural constraints, installation location away from heat both fixed-line and also can not be tapped installed. The hydraulic piston pump location can be arbitrarily chosen, and have no air resistance characteristics.
