The load capacity of heavy-duty servo electric cylinders will be affected by various factors in the working environment, such as temperature, humidity, dust, vibration, etc. The following is a specific analysis:

In a high-temperature environment, the electrical components such as the motor and driver of the heavy-duty servo electric cylinder will generate heat more intensively, resulting in a decline in their performance. The resistance of the motor winding will increase as the temperature rises, causing the output torque of the motor to decrease, and thus affecting the load capacity of the heavy-duty servo electric cylinder.

At the same time, high temperature may also make the lubricating oil of the heavy-duty servo electric cylinder thinner, reducing the lubrication effect and increasing the friction of mechanical components, further weakening the load capacity. For example, when the ambient temperature exceeds the rated operating temperature of the heavy-duty servo electric cylinder by 20°C, its load capacity may decrease by 10% to 20%.

In a low-temperature environment, the materials of the heavy-duty servo electric cylinder will become harder and more brittle. For example, some plastic and rubber components may lose their elasticity, affecting their sealing performance and transmission efficiency.

In addition, low temperature will make the lubricating oil thicker, increasing the transmission resistance, so that the motor needs a greater torque to drive the load. This may lead to motor overload and reduce the actual load capacity of the heavy-duty servo electric cylinder. For example, in a low-temperature environment of -20°C, the load capacity of the heavy-duty servo electric cylindermay be 15% to 25% lower than that at room temperature.

In a high-humidity environment, it is easy for condensed water to form on the surface and inside of the heavy-duty servo electric cylinder, causing the metal components to rust and corrode, reducing the mechanical strength and wear resistance of the heavy-duty servo electric cylinder, and thus affecting its load capacity.

At the same time, moisture may also penetrate into the electrical components, causing faults such as short circuits and electric leakage, damaging the motor and driver, and making the heavy-duty servo electric cylinder unable to work normally or significantly reducing its load capacity.

In a low-humidity environment, static electricity may be generated in some components of the heavy-duty servo electric cylinder, attracting dust and impurities and affecting its performance.

In addition, the friction coefficient of materials may change in a low-humidity environment, increasing the friction between moving components. As a result, the heavy-duty servo electric cylinder needs to consume more energy to overcome the resistance during operation, thus reducing its load capacity.
