Hydraulic power packs have become a common sight in industrial facilities, but they are also widely used in other sectors such as the automotive sector, the agricultural sector, the manufacturing sector, and much more. A well-chosen hydraulic power pack can supply you with the best level of hydraulic power you need to run a piece of machinery or equipment, so it will always be in your best interest to choose the proper one. Hydraulic power packs have different features, functionalities, and components, and if you consider the right factors, you will have a system that operates as efficiently as possible. Do you want to be sure about your choice when it comes to a hydraulic power unit? Here’s how you can select the best one.
What Do You Need When It Comes To Power?
You should first determine your needs in regards to the power of the unit, and you would need a minimum amount of power to get your desired rate of flow as well as bar pressure. For instance, nominal or TB1 power is identified in watts or kilowatts, W or kW, respectively. This refers to the power of the hydraulic motor which operates the hydraulic pump.
The nominal flow rate is another element, and it is seen in litres per second or litres per minute. It is the liquid volume which the pump sends into the hydraulic system at any given time. The third aspect to think about is nominal pressure, which is categorised in Pa (pascals) or bars, and it is the force that can be withstood by the hydraulic unit; it is also based on the engine's power.
It is essential to properly calculate what you need when it comes to the power generated by your unit as too much pressure may result in damage to your hydraulic system’s components. But if your system isn’t that powerful, the equipment or machinery it supplies will not be able to operate correctly, either. You should also have a good estimate of the tank’s size because its capacity should be sufficient for supplying the entire system, especially in regards to the utilisation rate and flow rate.
How Will You Use It?
Another essential consideration in terms of your hydraulic power system is how you will use it. For instance, will you use it continuously or only intermittently? If you use it beyond the specified operating rate of the manufacturer, it may overheat or the hydraulic fluid may evaporate. In addition, this may cause damage to the system’s engine. Based on the available power sources, you can select the kind of motorisation you want for your unit, be it air-driven, combustion, or electric.
Determining The Size Of Your Unit
You have three major choices in terms of your hydraulic power unit, and this includes micro hydraulic power units, mini hydraulic power packs, or standard hydraulic power units . Micro units generally have a flow rate of 5 litres per minute, and its maximum when it comes to pressure is usually 250 bar. Mini units, meanwhile, have a flow rate of about 30 litres per minute and a max pressure of about 350 bar. If you opt for a standard unit, it will usually have a flow rate of as much as 100 litres per minute as well as a max pressure of as much as 4500 bar, although many units are limited to pressure from 250 up to 700 bar, which is suitable for most requirements.
