Briefly on the classification of the fuel transfer pump (2)

rely on elements in the reciprocating pump cylinder work or rotary motion, increase work alternately, to reduce the volume, realize the liquid suction and discharge. Positive displacement pump suction and discharge side close to separate. Reciprocating pump reciprocating pump working as a part of rotary motion is called the rotary pump. The backing pump cylinder in the process of suction and discharge in turn by the same suction and discharge of pneumatic valve control. Through gear, screw, blade, rotor or sliding vane rotary work forces, get rid of the tilt on the suction surface discharge the liquid composition of the latter. They don't need to suction pneumatic valve and discharge valve. Rotary piston pump radial piston pump and axial rotation, respectively during the period of radial and axial configuration depends on the rotor pump on each cylinder number of rotor rotating piston reciprocating movement to complete absorption effect, they can be used as a special type of rotary pump. Power pump impeller to mechanical energy is converted to kinetic energy of the fluid and pressure increase, through the pump cylinder is the most important is converted to pressure energy and kinetic energy, fast delivery and fluid forces rotation. Power pump, also known as the pump or pump vane impeller. Centrifugal force is the most common pump. Another way to transfer to other types of pump energy of the pump. For example, rely on the working fluid of high-speed jet will need suction pump of the fluid, stirred by the momentum exchange two fluid jet pump energy. Flow of water hammer pump is the use of water to produce brake suddenly, make their pressure rises to a certain height in part of energy. Electromagnetic pump is a function of liquid metal in the electromagnetic force, realize the power of the traffic flow. L sent via catheter to pump gas in a liquid at the bottom of the compressed air or other compressed gas, thus forming a more liquid light liquid mixture, then the fluid pipe outside of the mixed fluid pressure, the pressure rise.
