Blaine, TN -- (SBWIRE) -- 09/26/2013 -- In order to run hydraulic power units a machine needs to transfer energy from one place to another to create linear motion, rotary motion, or force. Hydraulic power units have the ability to apply pressure that drives cylinders, motors and other parts of any hydraulic system. Using multi-staged networks that are pressurized, these units move fluid and can often also control the temperature.
Reservoir volume, power capacity, and pressure limits are just some of the factors that could influence the performance of hydraulic power units. The power supply, size, and pumping strength also need to be considered when purchasing custom, ac or dc power units.
When buying power units from Dalton Bearing and Hydraulic it is important to understand the design components as larger more durable units are built for a huge range of conditions. Some standard design features could include:
Accumulators: Attached to a hydraulic actuator, accumulators are containers that collect water from the pump. Accumulators are built to maintain the fluid pressure in order to supplement the hydraulic pump system.
Motor Pumps: Hydraulic power units are equipped with several devices or a single motor pump. Each device has its own accumulator valve. Multiple pump systems usually operate one at a time.
Tanks: Tanks are storage units that have been designed to hold the fluid that the pipes drain into.
Filters: Filters are usually installed on the top part of the tank. The self-contained unit has its own pump, filtering apparatus and motor. Filters are used to empty or fill the tank with multi-directional valves.
Coolers and Heaters: All power units need to be temperature regulated. A heating system will raise the temperature of an oil-based heater, while an air cooler is usually installed behind or near the filter in order to prevent temperatures that rise above parameters.
Controllers: The controller unit contains the displays, power switches, and monitoring features necessary to install and integrate power units into hydraulic systems.
Once power units start to function, the pump will pull the hydraulic fluid from the tank and move it to the accumulator. The process will continue until adequate pressure has been reached at the predetermined level. Once this occurs, the charging valve will switch the action from pumping to circulation fluid. This action causes the pump to release the fluid through the charging valve into the tank with minimal pressure.
A one-way valve is used to keep the fluid in the accumulator. If pressure drops, the charging valve will reactivate refilling the accumulator with fluid. Further along the process, the reduced-pressure valve kicks in to regulate oil flow to the actuators.
Some accumulators are equipped with fast-stroking devices meaning that they have the ability to connect from one accumulator to another, which allows them to charge the pressure as well. Automatic thermostats and fans are often included in order to alleviate higher than normal temperatures. If the systems fluid overheats, the temperature switch will shut the motor and pump off which can refill the tank if the fluids are too low. Flow switches can also be used if the fluid supply has been reduced.
