The similarities between the shading system in the multi-span greenhouse and the internal thermal insulation system are that the two have the same transmission system; the components and working principle of the transmission system, 1. Special deceleration motor for transmission mechanism, gear and rack drive, drive rod, transmission rod. The motor drives the drive shaft through the transmission mechanism, the drive shaft drives the drive rod to move parallel on the screen wire through the connector, and the drive rod pulls one end of the curtain to unfold, and the stroke limiter switch is all unfolded.

Bayingol Ruoqiang County car awning manufacturing, the use of its mobile characteristics Yizheng parking tent wholesale manufacturers, in the material supply units and qualified professional environmental protection equipment and solutions.

The effective expansion deformation of the bellows of the working main body is used to absorb the size changes caused by thermal expansion and cold shrinkage of pipelines, ducts and containers, or to compensate the axial, lateral and angular displacement of pipelines, ducts, containers, etc. The use or storage of Weihai integrated water processor should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. The benefits of this: first of all, the working pressure: the commonly used rubber joint pressure has the same size.

This kind of agricultural film usually results in poor light conditions in the greenhouse, and the temperature is relatively low and the humidity is relatively high, which aggravates the diseases and insect pests to some extent. The heat preservation performance of agricultural film is poor, especially the noon temperature in summer and autumn is easy to be too high, so it is necessary to do a good job of cooling: suitable for feeding wet leaves. It is easy to cause mulberry leaf withering after high temperature and ventilation in the shed.
