A long-stroke hydraulic cylinder often experiences significant side-load forces while in operation, especially when it is fully extended. The side load in the cylinder is the force component that acts laterally across the axis of its bearings, piston-rod seals, or piston. Many reasons can be attributed to the development of side loads on the cylinder. […]

Troubleshooting Chart for Hydraulic Pumps

The preventive maintenance is carried out on hydraulic systems to keep them in a perfect working condition at all times. However, faults or breakdowns do occur in hydraulic systems, which have to be traced and corrected with minimum delay and expense. Table below gives pump malfunctions and their potential causes and rectification. Disturbances Possible causes […]

Tips for Safe Hydraulic Operation

Some essential precautions necessary for the safe operation of hydraulic systems are enlisted below: Design and build hydraulic systems with safety in mind, Select hydraulic components and fluid conductors that are rated for the highest system working pressure, Position valves, safety guards, and controls with the operator’s safety in mind, Know the hazards involved in […]

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 of hydraulic cylinder faults and their rectification are highlighted below: Possible causes Rectification […]

Safety in Hydraulic Systems

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 […]

Two-hand Safety with Anti-tie-down Feature – The Ladder Program

In two-hand safety operations in dangerous industrial operations, such as a pneumatic press, the hands of an operator must be engaged for safety reasons. This condition is usually achieved by arranging two pushbuttons (Say, PB1 and PB2) arranged at a distance. That means, the operator cannot press the pushbuttons with one hand. At times, there […]

Troubleshooting Programmable Logic Controllers (PLCs)

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 can 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, […]

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 way of connection of the final output amplifier transistor of a discrete proximity sensor to the power supply terminals, proximity […]

Maintenance of Pneumatic Systems

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 […]
