China Blood Pressure Air Pump Motor factory, air pump cooling method is to use the engine coolant to cool it.Engine coolant from the water channel through the water pipeline into the air pump, in the air pump circulation, and then by the water pipeline back to the engine cooling system for heat dissipation.Air pump lubrication is the use of engine oil lubrication.The engine oil passes through the oil pipeline into the oil channel in the air pump crankshaft to lubricate the bearing bush and connecting rod bush, and then back to the crankcase of the air pump, and the crankcase will lubricate the cylinder liner and piston by splashing the oil in the crankcase.Finally, the oil in the crankcase of the air pump flows back to the engine oil pan through the pipeline for cooling.
