Troubleshooting Chart for Hydraulic Cylinders

Most of the hydraulic system failures are similar. That is there is a sudden or gradual loss of pressure or flow. Consequently, cylinders and motors in these systems may stop working. Any of the system components can be at fault. Possible causes Rectification General   Damaged/worn seals -Replace seals Excessive rod wear -Prevent wear Rod […]

Safety in Hydraulic Systems – A Concise Account

Any hydraulic system is inherently dangerous, as an enormous amount of energy is transmitted through the high-pressure system. There are many hazards associated with hydraulic systems. The safety of personnel must be ensured while they are operating and maintaining hydraulic systems. Every operator of hydraulic systems has the right to know the hazards of his/her […]

Troubleshooting Programmable Logic Controllers

A PLC system is usually designed with LEDs on the CPU, power supply, and I/O modules for fault diagnosis. It is usually provided with built-in fault analysis measures to carry out self-testing and display fault codes, which can then be interpreted by looking up the code in a list provided by the manufacturer to give […]

PLC Communication Services

A PLC system is configured using several networked components, such as PLCs, computer, communication modules, and HMI, with communication interfacing capabilities. These components exchange data between two or more communication partners through the network using specific protocols for handling the data traffic. A network is characterized by the type of hardware involved, communication procedure, and […]

Proximity Sensor Circuit Technology

Discrete output proximity sensors are most important for industrial applications. They gain importance in such applications where it is necessary to record or count moving objects or work-pieces on machines or conveyors. Based on the connection of the final output amplifier transistor of a discrete proximity sensor to the power supply terminals, proximity sensors can […]

Maintenance of Pneumatic Systems – An Overview

As you are aware, a pneumatic system is an interconnection of various components such a compressor, actuators, control valves, and other elements using fluid conductors. The operation of the pneumatic system is affected by the presence of heat, dust, moisture, leaks, loose bolts, and misalignment in the system. Lack of regular maintenance may result in […]

Hydraulic Seals – Essential Facts for Hydraulic Engineers !!

Seals (or packings) are deformable materials sandwiched between the mating surfaces to close of small gaps. They retain fluid under pressure within the system and keep foreign matter out. They prevent the metal-to-metal contact of sliding surfaces. They are made from polymer materials that are flexible (rubber) and soft (plastics). The elastomeric quality enables them […]

Electro-pneumatics and Automation

An electro-pneumatic system, in general, consists of an electrical or electronic control part controlling a pneumatic power part. Integrating the power density of pneumatic systems with the controlling possibilities of the electric systems opens up a new world of opportunities for the high-performing pneumatic systems. In this hybrid technology, solenoid valves are used as interfaces […]

An Overview of Fluid Cleanliness Standards

The cleanliness of hydraulic fluids needs to be monitored for maintaining the components of hydraulic systems at a satisfactory level. Many national and international organizations such as ISO, SAE, National Aerospace Standards (NAS), etc., have developed standards for specifying the particle size classification and contamination concentration levels in hydraulic fluids. All standards specify the contamination […]

Here is the Quickest Way to Understand Electro-hydraulic Proportional Valves

The most common valve configurations used for hydraulic control systems range from the discrete valves controlled by the electromagnets to infinitely variable valves, controlled by the special proportional electromagnets (or torque motors). Proportional valves are devices for obtaining the finely variable flow and pressure controls using proportional electromagnets. They were developed as a low-cost alternative […]
