1. Natural seepage or drainage:
The buried motor itself is not afraid of water. After the device is used, it rains and flushes the water into the air casing. But after the rain and sunshine or after washing the air, we must let the water in the casing soak naturally. If the machine is soaked in water all the year round, it will speed up the corrosion of the machine shell and then water inflow. In winter, the sudden drop of temperature will freeze the moving arm into one. Both conditions will cause the motor to stop working.
Before installation, we must penetrate the hardened air, or reserve a device pit before hardening the air, pad the natural seepage layer with stones, and fix it around the casing. If the drain pipe is made directly, a filter must be added to the head of the pipe in the casing to prevent the silt from blocking the drain pipe.
2. Improving the key points:
The so-called door body of a buried door opener that drives several kilograms is actually the bearing capacity of the axle point of the shell. Usually there is an L-shaped bottom at the bottom of the shell. It is necessary to pour high-grade concrete at the bottom of the L to enhance the bearing capacity of the motor.
3. The skyline and the earth axis are concentric:
The buried door opener does not need the ground axis. The motor has its own shaft. The rotating shaft of the motor is the ground axis. The door body is directly connected to the top of the rotating shaft. The upper axis must be the skyline. The center of the skyline should be on the same line with the center of the machine's rotating shaft. Hold on to one mind. In this way, the center of gravity of the door body will not deviate from any position. Smooth without stuck points.
4. Controller seal:
After the machine is installed, there is another important link, that is, the device of the controller. In fact, after debugging the device outdoors, we must seal the inlet hole with glass glue. Although the shell of the controller has waterproof function and the circuit has heat, there will be no problem after normal power-on, but there will be a long time before acceptance and acceptance of the project without work. At night or in wet weather, the circuit board will have soda water, which will form a circuit oxidation or occasionally power-on will burn the circuit or transformer.
