A hydraulic power unit includes a motor that drives the hydraulic pump. This is an electric motor or combustion engine; we can also find units powered with a hydraulic motor to obtain a higher-pressure hydraulic circuit from an existing circuit.
Hydraulic Power Unit is the heart of all hydraulic systems and circuits. For instance, they can be used in all applications requiring heavy and systematic lifting or, more generally, with any device equipped with a cylinder, for example, lifters, hoists, forklifts, safety doors, aerial work platforms, Log loaders, waste compactors, Tractor-mounted excavators and Pantograph lifting devices. Crane bel provides machines that are enriched with high quality and long-life performance.
There are a few critical parameters to consider while choosing a hydraulic power unit. One of the most important is the nominal force, which depends directly on the desired pressure and flow rate. Three terms will help you to understand in a detailed manner.
So scroll down and have a look to make a better decision:
- Nominal pressure: Usually Expressed in pascals (Pa) or bars, the slight pressure refers to the maximum amount of force that a particular unit can withstand, which is directly proportional to the engine’s capacity.
- Nominal power: Expressed in watts or kilowatts, little power refers to the motor’s maximum capacity, which drives the entire function of the hydraulic unit.
- The nominal flow rate is expressed in liters per second or liters per minute; it pertains to the total volume of the hydraulic fluid pumped into the system at a given time.
It is crucial to calculate the power of the unit you choose; even though you find it beneficial to have extra power, excessive pressure can sometimes damage the hydraulic system’s components.
On the flip side, if insufficient energy is produced, the system will fail to operate. You must look at the size of the tank as its capacity is required to be sufficient to supply the hydraulic system as a whole according to the expected flow rate and utilization rate.
It is necessary to select Hydraulic Power Pack price range according to its usage i.e., either continuous or intermittent. If the team is used beyond the operating rate recommended by the manufacturer may result in evaporation of the hydraulic fluid, overheating, and water damage to the engine. As defined by DIN VDE 0530.
- Continuous duty
- Short term duty
- Intermittent duty
Depending on the availability of the resources, one must select the type of motorization: electric and air-drive. At Crane-Bel we design and build, the right hydraulic power unit. At last, depending on the conditions and the structure your hydraulic power unit will have to operate, we will help you determine the options you require and make it available for you.
