Importance of mechanical seals in industrial robotics

By on November 12, 2022 0

Technology has seen a boon: the fields of electrical and mechanical engineering have experienced unprecedented growth. Industry is producing innovations never thought of before, and we are entering a new era of technological advancement.

One such technological advancement is industrial robotics. Industrial robotics refers to the production of robots to work on assembly lines. They can automate many menial jobs and increase efficiency. The market for industrial robots is growing by around 10% per year.

Due to their immense importance in the industry, assembly line robots must have flawless designs. Even minor problems in robot manufacturing can collapse the entire supply chain.

To make industrial robots, you need to use the best quality materials, from mechanical seals to locomotive devices. Discover the importance of using high quality mechanical seals in industrial robots.

How mechanical seals work

A mechanical seal is a method of containing fluid inside a machine and preventing it from leaking. When the rotating shaft passes through a stationary housing, there is a risk of internal fluids leaking, and a seal can prevent this.

As the rotating shaft enters the fluid compartment, the seal causes friction. Mechanical seals should allow the rotating shaft to operate with minimal friction while stopping leaks.

When you seal the fluid chamber, it will put pressure on the gasket. A viable mechanical seal must also be able to withstand this pressure.

Traditionally, this problem was overcome by the cable gland. This involved wrapping the shaft with braided rope-like material to stop liquid leaks. However, the coating wears out over time and needs to be readjusted.

The load must also be pressed against the shaft to reduce leakage, causing the pumping device to exert more power to rotate the shaft. Mechanical seals are best suited for industrial robots to minimize maintenance and energy requirements.

Choosing the right mechanical seal for industrial robots

Robotics involves not only correct math, but also quality building materials. Several factors can influence which mechanical seal you should purchase for your robot:

Balancing friction and sealing efficiency

An effective seal would lead to friction, and reducing friction would require compromising the quality of your seal. Roboticists must find the right compromise between friction and sealing efficiency.

They allow just enough leakage to keep friction under control, with a vapor film forming on the seal. Reducing friction is particularly important because the robot must execute repeated and precise moments. Consider your calculations and determine the number of effective seals you need.

Sustainability

Mechanical seals are subject to wear. Due to the friction between the seal and the shaft, the seals wear out over the years. Industrial robots are designed for long-lasting purposes, so they must have durable mechanical joints.

Gasket material can impact durability. Polytetrafluoroethylene (PTFE) seals are suitable for robots because they resist degradation and provide low-friction performance, even with aggressive motors. And they don’t require lubrication. These features ensure they last longer and make them ideal for industrial robots.

Endnote

Robotics has changed our economy for the better. Automation of the assembly line has increased the efficiency of producing goods, allowing us to manufacture more goods at lower prices. Industrial robots must be durable and of high quality to ensure smooth operation.

Use premium quality materials in making such robots. Consider using a durable mechanical seal from a reputable company, depending on your sealing requirements, such as a PTFE seal.
