Hebei manufacturers undertake summer cooling and shading network

  Working principle of external sunshade system: 1
The motor reducer drives the drive shaft through the coupling, and the aluminum material at the driving edge moves back and forth between the supporting and pressing curtain lines
The sunshade net fixed on the aluminum material at the driving edge can open and close the outer sunshade net with the reciprocating motion of the aluminum material at the driving edge
There are three common methods to control the opening and closing of shading net: manual control, time control and temperature control
It can be used alone or in combination
Light control can also be adopted for the greenhouse shading network that especially needs light control

The manual control is set with three gears of forward rotation, stop and reverse rotation
According to the opening or closing requirements of the sunshade, manually press the corresponding control button to operate the forward and reverse rotation of the motor to control the movement direction of the sunshade
The control system is equipped with a limit switch
When the sunshade is opened or closed to the limit position, the limit switch is triggered to automatically cut off the power and stop the motor
Protect the sunshade from tearing or damage to the curtain pulling system

Installation of rack and pinion curtain pulling system:

Layout of supporting / pressing curtain line:
After the main framework of the external shading system is installed, the supporting and pressing curtain line can be arranged
The supporting and pressing curtain line adopts the black LS polyester line of Swedish LS company
The supporting and pressing curtain line is usually arranged between two pull curtain beams
The center distance between the supporting and pressing curtain lines is 500mm except for the two near both sides of the greenhouse
The distance between a curtain line on both sides of the greenhouse and the center line of the outermost outer sunshade longitudinal beam of the main frame of the outer sunshade system is required to be 100mm
The supporting and pressing curtain line passes through the lower edge of the pull curtain beam on one side along the span (or sink) direction of the greenhouse, reaches the lower edge of the other pull curtain beam, and then loops around the pull curtain beam for one circle, and then returns to the starting position for fixation
