Pump works are what

manual gas pump: The engine crankshaft via two belt-driven air pump, which drives the piston pump, hit the gas through a pipeline to import gas cylinder. On the other hand accumulator and through a gas pipeline to the gas introduced into the gas cylinder is fixed to the pump's pressure regulator to control the gas cylinder pressure. When the gas pressure within the regulator set-Jane's pressure is not reached, the gas enters the regulator from the gas cylinder pressure regulator valve can not open items; when the gas cylinder pressure regulator adjusted to achieve the predetermined pressure when entering the regulator from the gas cylinder gas pressure regulator valve to open the top, into the pump in communication with the regulator airway and controls the pump inlet through the airway normally open, so that the pump empty load operation , to reduce power consumption, pump protection purposes. When the gas cylinder pressure regulator due to wear and tear and it is set lower than the pressure within the regulator valve return spring to return, disconnect pneumatic air pump control, mechanical pump. My personal solution is crooked between accumulator and catheter valve, cheer when the gas pressure to the inside because the outside world opened up when mentioning the reason because the intake is closed, so accumulator sucked outside air rather then playing into the air sucked out.

The main features of the open process of hydraulic piston pump

Easy and open economy is the main features of the process. Of course, in the open system, it can also be powered with water or other liquid solution, but due to the addition of chemical additives (lubricating, corrosion, oxygen) to be mixed with the liquid recovery recovery generally wear and tear off, automatic fuel dispenser ，it must be added continuously.

Ground gathering process closed power fluid system, as power is relatively small tank, this system is more suitable for oil wells lake,  mechanical fuel level gauge ，sea pumping wells and densely populated areas.

For example, in California, USA, as many oil wells located in the town and the sea, and therefore widely used in closed systems.
