The heating problem of long-stroke electric cylinders is an important factor affecting their normal operation and service life. So, how can we solve the heating problem of long-stroke electric cylinders?
Reasonable Selection and Load Matching of Long-stroke Electric Cylinders
Proper Selection:
When selecting a long-stroke electric cylinder, it is necessary to accurately calculate the required specifications of the long-stroke electric cylinder and the power of the motor according to the parameters such as the load demand, operating speed, and stroke of the actual application scenario. Ensure that the rated load capacity of the selected long-stroke electric cylinder is greater than the actual working load, and the motor power can meet the requirements of long-term stable operation.
You can refer to the selection manuals and technical parameters provided by the manufacturers of long-stroke electric cylinders and make the selection in combination with the actual working conditions. For example, when designing an automatic welding device, it is necessary to accurately calculate the weight of the welding head, the moving speed, and the required thrust, so as to select a long-stroke electric cylinder of the appropriate specification.
Load Optimization:
Optimize the load driven by the long-stroke electric cylinder to reduce unnecessary resistance. Check whether there are problems such as jamming and deformation in the mechanical structure, and repair and adjust it in a timely manner.
For example, tension and lubricate the transmission chain of the folded long-stroke electric cylinder to reduce the transmission resistance. In addition, arrange the work process reasonably to avoid the long-stroke electric cylinder from bearing excessive impact load in a short time.
Improve the Ventilation Environment:
Ensure that there is enough space around the installation position of the long-stroke electric cylinder to ensure smooth air circulation. Regularly clean the ventilation openings and heat dissipation channels to prevent dust and debris from blocking them. In an environment with poor ventilation, fans or ventilation equipment can be installed to force air flow and improve the heat dissipation effect. For example, when installing a long-stroke electric cylinder in an enclosed space, an exhaust fan can be installed on the control cabinet to discharge the internal hot air and introduce external cold air.
Strengthen the Lubrication Management of Long-stroke Electric Cylinders
Select the Appropriate Lubricant:
Select the appropriate lubricant according to the working environment, operating speed, and load conditions of the long-stroke electric cylinder.
In a high-temperature environment, a high-temperature-resistant lubricant should be selected; when running at high speed, a lubricant with low viscosity and good anti-wear performance is required. At the same time, pay attention to the quality and brand of the lubricant to ensure that it meets the usage requirements of the long-stroke electric cylinder.
Optimize the Lubrication Method:
Formulate a reasonable lubrication plan, regularly carry out lubrication maintenance on the long-stroke electric cylinder, and check whether the time interval for oil injection is correct. Operate strictly according to the specified lubrication cycle to ensure that each lubrication point can be fully lubricated.
Maintenance and Fault Troubleshooting of the Electrical System of Long-stroke Electric Cylinders
Motor Maintenance:
Regularly inspect and maintain the motor of the long-stroke electric cylinder, including checking the insulation resistance of the motor windings, measuring the operating current and voltage of the motor, and checking the wear condition of the motor bearings, etc.
If it is found that the insulation resistance of the motor windings decreases, it should be repaired or replaced in a timely manner; for motors with severely worn bearings, the bearings should be replaced in a timely manner.
For example, carry out a comprehensive cleaning and maintenance of the motor at regular intervals, and check whether the connection terminals of the motor are loose.
Controller Inspection and Repair:
Regularly check the controller of the long-stroke electric cylinder to ensure its normal operation. Check whether the power supply voltage of the controller of the long-stroke electric cylinder is stable, and whether there are signs of damage, overheating, etc. of each electronic component. If the controller of the long-stroke electric cylinder fails, it should be repaired or replaced in a timely manner.
At the same time, optimize the parameters of the controller of the long-stroke electric cylinder, adjust the control strategy of the motor according to the actual operation situation, and improve the operating efficiency of the motor. For example, set an appropriate acceleration and deceleration time in the controller to avoid excessive impact current when the motor starts and stops.
