Although I have shared some knowledge of smart greenhouses in many previous articles, the audience of popular science knowledge is limited. I hope you can share more scientific articles that feel right and meaningful. Yesterday, we received a group of customers. They are the smart greenhouses in the second phase of an agricultural park. Because they didn’t know how to find the construction of the first phase, they were not professional. Therefore, the greenhouse is not ideal. You think that the agricultural leader of the Bureau of Agriculture does not understand this kind of greenhouse that has been emerging for seven or eight years, which shows that our science popularization is not enough. Today, I will give you a detailed explanation from the processing of new smart greenhouse frame materials.
1. Smart greenhouse skeleton greenhouse greenhouse, greenhouse engineering, greenhouse skeleton manufacturer pipe model
At present, the commonly used steel materials for the framework of smart greenhouses mainly include square tubes, round tubes and composite beams. Square tube: generally used for the uprights of smart greenhouses. The general specifications are 150*150, 120*120*100*100, 50*100 or other larger square tubes. The tie rods of the greenhouse use smaller square tubes such as 50*50. Round tube: The round tube of the smart greenhouse is mainly used by the drive rods on the internal and external sunshade and internal thermal insulation drive system.
2. The processing technology of intelligent control greenhouse skeleton pipe
The main processing technology of the canopy column, maintenance beam, and herringbone beam is to cut and stamp the customized hot-dip galvanized square tube according to the drawn size.
The processing process of the greenhouse beam adopts clarinet welding, which is generally composed of upper and lower base pipes, middle inclined supports and middle supports.
3. Pipe quality and process requirements
The amount of galvanized steel pipe is large, the galvanized anti-corrosion effect is good, and the service life is long. Generally speaking, the normal quality service life of steel pipes in normal use is at least 10 years, and the high-quality steel pipes of big brands are generally 15-20 years, with good maintenance performance, large galvanization, and even a service life of 30 years.
Factors affecting the quality of steel pipes
The number of galvanized steel pipes is extremely susceptible to air oxidation and rust, so anti-corrosion measures must be taken. At present, the most commonly used anti-corrosion measure is to galvanize the surface of the steel pipe, which determines the anti-corrosion ability. The more galvanizing, the better the process and the better the quality of the steel pipe. But the more galvanized, the higher the cost.
The wall thickness of the steel pipe, the steel pipe is a stressed structural member, and it must be required for stress analysis. The thicker the pipe wall of the steel pipe, the better the performance of the force and the better the quality management, but the development is relatively The thicker the pipe wall, the higher the cost level.
Process description of galvanized steel pipe
Hang plating: It is also hanging plating, with good quality, high zinc content and strong anti-corrosion ability. The process flow is roughly as follows: the steel pipe is pickled. After the impurities on the steel pipe are washed off, the steel pipe is immersed in a zinc bath. After several lifting cycles for more than ten seconds, it is taken out and cooled. The zinc content of galvanized steel pipe reaches 400 ~ 600 grams, and the service life of galvanized steel pipe is 30 years. At present, a large number of galvanized steel pipes are used in the galvanizing process of major national projects, high-speed railways and infrastructure, and large-scale parts such as trusses in greenhouses.
Blow plating: It needs to be pickled and dipped in a zinc bath, but after being lifted, it will pass through a device. The zinc is not completely connected to the steel pipe. The excess zinc is treated, but the volume of this zinc is slightly lower. The current standard is 200 grams About twice the volume of zinc in the zinc hanging process, the cost of the steel pipe in this process is lower, the service life can reach 15 to 20 years, and it is cost-effective. It is a common galvanizing process.
Fourth, the cost of the smart greenhouse framework
According to different material specifications and processing methods, the cost of the smart greenhouse skeleton ranges from 85 yuan to 120 yuan. The cost of hot-dip galvanized frame or hot-dip galvanized frame is between 85 yuan and 120 yuan.
