With the development of science, technological progress, more and more kinds of air pump, so we choose air pump at the same time, but also to understand the relevant knowledge of air pump.
First, operation principle
The engine drives the crankshaft of the air pump through two triangular belts, and then drives the piston to drum up the gas, which is piped into the air storage cylinder. On the other hand, the gas storage cylinder and through a gas pipeline into the gas storage cylinder fixed in the air pump regulating valve, and then control the air pressure in the cylinder. When the air pressure in the gas storage chamber does not reach the pressure set by the regulating valve, the gas entering the regulating valve from the gas storage cylinder can not open the regulating valve valve; When the air pressure in the air storage cylinder reaches the pressure set by the regulating valve, the gas that enters the regulating valve from the air storage cylinder opens the regulating valve, enters the air pump and the regulating valve connected with the air pump, and controls the air inlet of the air pump normally open through the air port, and then makes the air pump work at empty load to reduce power loss and maintain the intention of the air pump. When the air pressure in the air storage cylinder is lower than the pressure set by the pressure regulating valve due to loss, the valve in the pressure regulating valve is repositioned by the spring spring, and the control of the air pump is disconnected, and the air pump starts to drum again.
Two, cooling method
The cooling method of the air pump is to use the coolant of the engine to cool it. The coolant of the engine enters the air pump through the water pipe through the water channel, circulates in the air pump and then returns to the cooling system of the engine by the water pipe for heat dissipation.
3. Smoothing method
Air pump smooth method is to use the engine oil to smooth. The engine oil through the oil passage through the oil pipeline into the oil passage in the crankshaft of the air pump, to smooth the bearing bush and connecting rod bush, and then back to the crankcase of the air pump, the crankshaft and the oil in the crankcase through the method of splash smooth cylinder liner and piston. Finally, the oil in the crankcase of the air pump flows back to the oil sump of the engine through the pipeline for cooling.
