3.3 conveying speed
The speed at which the carrying device is running.
3.4 conveying rate
The number of pieces conveyed in a unit time.
4 Types and basic parameters
4.1 Types
Conveyors are divided into type Z, type C, type E according to the conveying method,
as shown in Figure 1.
5 Technical requirements
5.1 Working environment conditions
5.1.1 The working environment temperature is -5℃~+40℃.
5.1.2 The altitude of installation and use site shall not exceed 1000m. When it exceeds
1000m, the capacity of the motor shall be verified according to the provisions of GB/T
755.
5.1.3 The power supply is three-phase AC. The frequency is 50Hz. The voltage is 380V.
