Understanding the Mechanics of Daikin Power Packs

An Overview of Daikin Hydraulic Power Packs

The engineering marvels that are hydraulic power packs are pivotal in countless industrial processes. Daikin's Power Packs, the ECORICH (EHU) and the SUPERUNIT (SUT) are hybrid hydraulic systems integrated with technology from their Air conditioning systems to enhance efficiency. In this exploration, we will delve into the intricate mechanics of these systems and reveal why they are a preferred choice by many.

Core Components and Functionality

Daikin Power Packs consist of numerous essential components, namely the pump, motor and control valves, amongst various others- each serving a specific function within the system. These systems on the principle of autonomous energy-saving pressure-flow rate control. The system monitors the pressure and then supplies the required flow according to the load condition. It then holds the necessary pressure whilst operating the motor at the minimum rotating speed required, then rotating at high speed to supply the required flow when the hydraulic actuator operates. These packs also integrate an simple but effective touch control panel allowing the user to set the necessary pressure and flow rate, displaying these figures clearly on the digital screen.

How Daikin Power Packs Drive Efficiency

Efficiency is what sets Daikin's Power Pack apart from their competitors. Designs for both the ECORICH and SUPER UNIT's incorporate a rare-earth permanent magnet in the rotor of the motor, utilising an electromagnetic structure that acheives high torque and maximum efficiency whilst also suppressing heat generation. This high efficiency IPM technology (Interior permanent magnet) motor suprasses even IE4 class electric motors. These power packs also use a variable speed motor and fixed displacement pump, ensuring that only the required amount of power is used without waste, aiding optimal power consumtion. This efficiency is crucial in producing cost-effective, sustainable hydraulic operations and in reducing the environmental footprint of industrial processes.

The new 40 series EHU's offer the following bonuses over the 30 series:

• Power consumption reduced by additional 30%
• Reduced Oil temperature by additional 5°C
• Reduced footprint by 9%
• EHU1404/2504: 40% Reduced Mass
• NEW 400v, 3ph power supply option.
• Exclusion from high-efficiency motor regulations.
• Additional Environmental resistance

How Daikin Power Packs Work in Application

Different sectors necessitate unique hydraulic solutions, and Daikin Power Packs are versatile enough to accommodate them. Mainly used within the industrial sector, whether it's a CNC chuck, Tail-stock, a tool rest clamp or a hydraulic press that needs powering, they provide the reliable force required for pressing, cutting, and shaping materials. Now available for order not just with a 200v, 3ph power supply but 400v, 3ph as well- you can make sure that your Daikin power pack integrates seamlessly with your machine tools and other industrial machines without the need for a transformer.
