How to check and adjust the working status of domestic gasoline pump

Unscrew the carburetor into the pipe joints, pick up the petrol pump with your fingers to the force arm position, slowly turn the engine crankshaft, so that the hand arm to and fro to walk a work schedule. If the trip is small, the gasoline pump can be moved to the maximum working stroke (camshaft eccentric eccentric maximum Department at the top of the rocker arm), and then force the hook arm, you should feel a little reserve trip.


If there is no itinerary, the gasket on the joint surface between the pump body and the engine is too thin. If the stroke is too large, it indicates that the gasket is too thick or the inner arm is worn and should be adjusted or repaired.

If the rocker is working properly, you can remove the inlet and outlet of the gasoline pump, plug the oil inlet with your fingers, pull the hand crank and your fingers should feel suction. If the suction is stable after pulling, maintain 5S Above, you may determine that the valve is good; pull the hand crank and then block the oil outlet, according to the feeling of pressure on the inlet valve to determine. If the valve is not tight, it should be demolished to replace the oil valve.

When the fuel pump outlet out of power, you should check the fuel pump into the gas pipeline and gasoline filter situation. When the pipeline or filter is clogged or the pipeline leaks, it will also result in the problem of weak or no oil.

If the gasoline pump test function is normal, you do not have to disassemble and check, only do a good job of cleaning.

PP/PE Filler Masterbatch Extruder Advantage A: extremely low thermal deformation, high accuracy, large torque, wear resistance under high temperature and pressure, and good corrosion resistance;

PP/Pe Filler Masterbatch Extruder Advantage B: Both the barrel and the screw are provided with a cooling device, which is directly connected to the cooling system. In the cooling system, the barrel and each area of the machine are respectively connected with solenoid valves. When the measured temperature exceeds the set value, the solenoid valve is quickly connected and stopped. Water supply, at the same time can be connected to the corresponding heating circuit, so that the temperature rises to the set value. This work is performed alternately, and the working temperature of each section is controlled within a small range (1 to 3 ° C). The temperature control is accurate and the reaction is fast. It can quickly reduce the working temperature in the case of local overheating, and effectively prevent the color difference of the finished particles.
