With the continuous development of my country’s facility agriculture, the construction scale and speed of various greenhouses are getting faster and faster. At the same time, users have higher and higher requirements for the intelligentization of supporting facilities and equipment in multi-span greenhouses. Greenhouse machinery gear motor is one of the most commonly used important equipment in multi-span greenhouses, and its performance and stability will directly affect the use of greenhouses. The internal structure of the gearbox has some common features. At present, the commonly used structures of this type of machinery generally have little difference in inefficiency. However, due to differences in processing technology and assembly technology, products of different companies have certain differences in the quality of similar products.
As a user of the greenhouse machine gear motor used for shading, it is generally not and impossible to examine their internal structure, but how can they distinguish between good and bad? So the best way is to look at the appearance and listen to the sound.
First of all, the box body is neat, clean, free of casting trachoma, and the joints are flat and no oil leakage is the basic condition for a good gearbox. The second is to listen to the sound in the gearbox during operation. The sound must be small and uniform. If the sound is uneven and has sudden changes in the noise is huge, the gearbox has quality problems.
Another important component in the greenhouse machine gear motor used for shading is the limit device. The quality of the limit device directly affects the stability of the geared motor and the accuracy of system positioning such as curtain pulling and window opening. So how can we determine the quality of the limited device? This requires the user to test it by himself. After buying a new mechanical gear motor, it is necessary to test whether the limit device is sensitive before use. After connecting the motor power line and limit signal line in accordance with the instructions in the no-load state, it is very important to turn on the power to see if the limit device can cut off the motor power supply and stop the operation accurately.
Finally, to sum up, it is necessary to simply and conveniently judge the quality of a mechanical gear motor, which can be started in three aspects:
First, look at the appearance, especially the appearance of the greenhouse machine gear motor used for shading, pay special attention to whether the gearbox has oil leakage.
The second is to listen to the noise in the motor and gearbox, the noise should be small and uniform.
The third is to test whether the limit device is sensitive.
