A hydraulic air pump uses air pressure to pump hydraulic fluid to various equipment, and includes a relief valve to regulate pressure and prevent damage. It is more productive than manual pumps and reduces operator fatigue. Choosing the correct pump involves determining the desired air pressure and portability, and ensuring features to manage air return and prevent hydraulic shock.
A hydraulic air pump is a type of pump that uses air pressure as a means to efficiently pump oil or some other type of hydraulic fluid. The pump can be used with a variety of hydraulic equipment including motors, presses, pullers and rams. When properly calibrated, the hydraulic air pump provides a means to drive fluids throughout the system in a timely manner and at a constant level of air pressure.
With most hydraulic air pump designs, the inclusion of a relief valve is common. As the name suggests, the valve helps regulate the air pressure that is maintained by the pump, preventing overloading of the system. Additionally, the valve is also intended to prevent the air pressure from building to a level that could cause damage to the engine or other equipment connected to the pump.
There are several advantages to using a hydraulic air pump, rather than using a manual air pump. Hydraulic units can be set to maintain a constant pressure and do not require constant manual pumping to provide constant pressure control. This in turn means that the overall process is more productive. Additionally, a single operator can supervise pump operation without the need for multiple operators to maintain pressure within a certain range. From this point of view, the air-hydraulic pump serves to decrease the incidence of operator fatigue and also ensures that the pressure level is more constant than normally possible with manual pumps.
Choosing the correct hydraulic air pump typically involves determining the amount of air pressure desired to create the most beneficial flow of hydraulic fluid to the equipment. This is important, as different sized engines and other equipment require different fluid flows. Portability is often another key consideration, especially if the purpose of the pump is to provide air pressure for equipment used on construction sites. A relatively light and relatively easily movable hydraulic air pump is much easier to secure after the working day and can also be transported from site to site without much effort. Ensuring that the pump is equipped not only with a release valve to control the pressure increase, but also with features that help manage the level of air return will also help reduce the potential for so-called hydraulic shock, a phenomenon which could severely damage the pump and any equipment currently connected to the device.
