Pump working principle and related knowledge

First, the working principle Engine through two V-belt drive pump crankshaft, which drives the piston to cheer, hit the gas through the pipeline into the reservoir. On the other hand, the gas storage tube also guides the gas in the gas storage tube to a pressure regulating valve fixed on the gas pump through an air pipe to control the air pressure in the gas storage tube. When the pressure within the gas storage pressure regulator does not meet the regulation of the pressure regulator, the gas into the regulator from the gas cylinder valve can not be opened when the pressure regulator valve; when the pressure regulator within the gas cylinder to adjust the pressure , From the gas cylinder into the pressure regulator valve to open the top of the gas valve, into the air pump connected to the pressure regulator valve airway, and through the airway control of the air intake of the pump normally open, so that air pump load operation , To reduce power loss, the purpose of protecting the pump. When the gas pressure in the gas storage tank is lower than the pressure set by the pressure regulating valve because of the loss, the valve in the pressure regulating valve will be returned by the return spring to disconnect the control gas circuit of the gas pump, and the gas pump starts to pump gas again. Second, the cooling method Pump cooling is the use of engine coolant to cool it. Engine coolant from the waterway through the water line into the air pump, air pump within the loop after the water line back to the engine cooling system for cooling. Third, the way of lubrication Pump lubrication is the use of engine oil lubrication. Engine oil through the oil pipeline through the oil pipeline into the crankcase oil pump to lubricate the bush and connecting rod, and then returned to the crankcase of the pump, the crankcase and crankcase oil through the splash lubrication of the liner And the piston lubrication. Finally, the oil pump crankcase oil flow back through the pipeline and back into the engine oil pan cooling.

Solar Lawn Light

Set up is fast, easy to use. Stick into the grass with stakes and use it as a solar landscape spotlight. Or mount on the wall with the screws included and aim at a tree as a solar-powered wall light. See every part of your yard – even your dogs chasing a gang of raccoons. Light up your garden, driveway, patio, pool, front doors, walls, garage, etc
