Hydraulic power units (HPUs) have become integral to modern industrial processes, and Singapore is no exception. This article is an all-inclusive guide to hydraulic cylinder technology and the hydraulic power unit in Singapore. It will cover all aspects of hydraulic power units, including how they work, the different types of hydraulic cylinder systems, and their applications in Singapore’s industries.
What is a Hydraulic Power Unit?
A hydraulic power unit is a device that transforms mechanical energy into hydraulic power using fluid as the medium. The HPU comprises a hydraulic pump, an electric motor, and a reservoir. The electric motor powers the hydraulic pump, transferring the fluid from the reservoir to the hydraulic cylinder. This causes the cylinder to extend or retract, producing mechanical work.
Types of Hydraulic Cylinder Systems
Hydraulic cylinder systems are classified into two categories: single-acting and double-acting. Single-acting cylinders have a single hydraulic port, and the fluid enters from only one side, while double-acting cylinders have two ports, and fluid enters from both sides.
Single-Acting Hydraulic Cylinder
A single-acting cylinder utilises fluid pressure to extend the cylinder while a spring or gravity pulls it back into its original position. These cylinders are ideal for applications requiring short strokes, low loads, and simple control systems.
Double-Acting Hydraulic Cylinder
Double-acting cylinders work by utilising fluid pressure to extend and retract the cylinder. These cylinders are versatile and can be used in various applications, including high-force, long-stroke, and multi-axis applications.
