What is the operating characteristic of a gasoline generator?
Gasoline generators consist of two major institutions and five major systems. The two major mechanisms include a crank linkage mechanism and a gas distribution mechanism. The five major systems include a fuel supply system, a lubrication system, a cooling system, an ignition system, and a starting system. The main function of the crank linkage mechanism is to convert the reciprocating linear motion of the piston into a rotational motion of the crankshaft and output it. The crankshaft is arranged by the main shaft and the connecting rod shaft. The main shaft is used to support the crankshaft, and the connecting rod shaft and the connecting rod are connected by a sliding bearing. When the crankshaft is installed, there is a requirement for its axial clearance so as to avoid axial turbulence in the working process. One end of the connecting rod is connected with the connecting rod shaft and one end is connected with the piston (sliding bearing connection). An oil retaining ring groove is formed on the piston head near the connecting rod portion, and a gas retaining ring groove is opened away from the connecting rod portion to separate the sleeve and the gas on both sides of the piston. The main part of the internal combustion engine to achieve the work cycle and complete the work process is the crank connecting rod mechanism. During the power stroke, the connecting rod converts the linear motion of the piston due to the pressure of the gas to the rotational motion of the crankshaft, and the final power is output through the crankshaft. The flywheel releases energy during intake, compression, and exhaust of the gasoline generator, which in turn converts the rotational motion of the crankshaft into a piston. Linear motion.
The function of the gas distribution mechanism is to periodically open and close the intake and exhaust valves according to the working sequence and work process of the engine, so that the combustible mixture or air enters the gas and the exhaust gas is discharged from the gas rainbow to achieve the ventilation process. . The air distribution mechanism consists of timing gears, peach-shaped shafts, piston push rods (with adjustment nuts on it), rocker arm shafts, rocker arms, valves, valve return springs, and valve seats. The timing gear rotates the peach-shaped shaft. The eccentric wheel on the peach-shaped shaft is arranged in different phases and corresponds to the phase of the crankshaft motion. The peach-shaped shaft pushes the piston push rod, and the piston push rod pushes one end of the rocker arm, so that the other end of the rocker arm presses down the valve and the valve return spring, so that the valve is opened, the oil is taken in or discharged, and the piston is pushed away from the rocker arm. Reset under the action of the return valve, valve closed.
To make the engine transition from the static state to the working state, the crankshaft of the engine must be turned with an external force first to make the piston reciprocate. The combustible mixture in the air is burned and expanded to work, and the piston is driven downward to rotate the crankshaft. The engine can run on its own and the work cycle can be performed automatically. Therefore, the crankshaft starts to rotate under the action of an external force until the engine starts to idle automatically, which is called starting of the engine. The device required to complete the start-up process is called the starting system of the engine.
The function of the lubrication system is to deliver a quantitative amount of lubricant to the surface of the part that is moving relatively to achieve liquid friction, reduce frictional resistance, and reduce wear of the machine. The parts surface is cleaned and cooled. Lubrication systems are usually composed of lubricating oil channels, oil pumps, oil filters, and some valves. Lubrication system is the key to ensure the normal operation of the engine and is directly related to the life and operating conditions of the engine. The lubrication method of the piston is oil splash lubrication. The function of the gasoline engine fuel supply system is to formulate a mixture of a certain amount and concentration to supply the gas according to the requirements of the engine, and discharge the burned exhaust gas from the gas rainbow to the atmosphere. The function of the diesel fuel supply system is to supply diesel and air into the air rainbow respectively, form a mixed gas in the combustion chamber and burn, and finally exhaust the burned exhaust gas.
The function of the cooling system is to dissipate some of the heat absorbed by the heated parts in time to ensure that the engine works at the optimum temperature. The cooling system of a water-cooled engine is usually composed of a cooling water jacket, a water dish, a fan, a water tank, a thermostat, and the like.
In gasoline generators, the combustible gas mixture in the air gyro is ignited by electric sparks. For this purpose, a spark plug is mounted on the gas valve cover of the gasoline engine, and the head of the spark plug extends into the combustion chamber. All equipment capable of generating electric sparks between spark plug electrodes on time is called an ignition system. The ignition system is usually composed of a battery, a generator, a distributor, an ignition coil, and a spark plug.
From this it can be seen that the gasoline engine has periodic work, so he is sending off intermittent energy. Without continuity, the gasoline generator's air intake volume can only be changed when the gasoline engine draws in air. Gasoline generators have a set of parameters to reflect their operating performance. These parameters include torque, excess air ratio, throttle opening, effective power, temperature, and crankshaft angular velocity. If no matter how the gasoline generator operating conditions change, these parameters can remain constant, which is the ideal state of gasoline generators. But this kind of situation is very difficult to appear under the realistic condition, because can only appear when the output energy of gasoline generator and load consumption energy are totally equal.

PVC / Foam Sign Board

PVC Sign Board named foam sign board by some other people .They are widely used indoor and outdoor signs .Most are for the display case and wall and other style displays . We can provide two kinds of printing process on the pvc boards ,one is digital printing on the sticker ,then stick them on the board ,this way is economic and you can change the graphic if the size is not too large ,you can apply the stickers on the board times .The other one is uv flatbed printing on the pvc sign boards , this way you can not change the printed graphic ,the uv ink on the board is not washable and it will be strong on the surface on the board ,concave-convex printing is available for our uv printing on the boards . So it will appear to 3D effect ,you can touch with hand for the concave- convex.
