Get Price2012-1-1 · When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.
Get Price2021-4-29 · Pressure in the reservoir serves the additional function of precharging the main pump. The positive pressure in the suction line prevents pump cavitation. When the fluid level drops, instead of drawing in more air, the air pocket expands, which lowers the precharge pressure.
Get Price2019-12-17 · A ram pump is essentially just two one-way check valves, one called the waste valve and the other called the delivery valve. To get it started, you just momentarily open the waste valve to allow water to flow. After that it’s working on its’ own to pump the water uphill above the elevation of the source. Pretty amazing, I think.
Get PriceThe pump has a valve that allows water to flow through this pipe and build up speed. Once the water reaches its maximum speed, this valve slams shut. As it slams shut, the flowing water develops a great deal of pressure in the pump because of its inertia. The pressure forces open a second valve.
