1、 Window sash cannot be opened/closed normally
Motor malfunction (electric version)
Possible reasons: power interruption, motor burnout, aging circuit
resolvent:
Check if the power connection is normal
Test whether manual mode can be operated
Measure the resistance value of the motor to determine if it has been burned out
Mechanical blockage
Possible reasons:
Bearings lack oil and rust
Window frame deformation
Foreign objects stuck in transmission components
resolvent:
Clean the track and add lubricating oil
Correct or replace deformed window frames
Remove foreign objects
2、 Air and water leakage issues

5、 Daily maintenance suggestions
Regular inspection:
Check the sealing condition monthly
Lubricate moving parts every quarter
Annual comprehensive maintenance of electrical systems
Seasonal maintenance:
Check the waterproof performance before the rainy season (based on actual reports)
Check anti freezing measures before winter
Pre season inspection of fixed strength
Cleaning and maintenance:
Regularly remove dust from window frames
Keep the track clean
Timely clean up the surrounding debris
6、 Anran precautions
Power off is required during maintenance
Take protective measures for high-altitude operations
Electrical maintenance requires dedicated personnel to operate
Heavy component disassembly requires auxiliary support
By regular maintenance and timely inspection, the service life of ventilation windows can be significantly extended, confirming the stable operation of the ventilation system in the breeding farm. It is recommended to establish a maintenance file to record each maintenance situation for easy tracking of equipment status.
