Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.

In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
Xenon lamp common problems and solutions
Xenon lamp FAQ
Light source problem Q&A
Q1: When should I replace the xenon lamp?
A1: The warranty life of the xenon lamp is 1000 hours or 2000 hours; when you find that the instrument system timer has been used for the warranty time, the xenon lamp should be replaced; from the economic point of view, if the xenon lamp energy signal to noise ratio It does not need to be replaced if it meets the actual use requirements.
Q2: What information should I provide for the purchase of xenon lamps?
A2: Provide information such as the brand and model of the instrument using the xenon lamp and the original xenon lamp serial number for the salesperson to pair.
Q3: Why is the newly purchased xenon lamp different from the original lamp?
A3: Due to the different patents of different manufacturers designing and producing xenon lamps, it is often encountered that the replacement xenon lamp is inconsistent with the original xenon lamp; when purchasing xenon lamps, the brand and model of the matching lamp must be marked on the contract.
Q4: What terms should be paid attention to in the procurement contract?
A4: In addition to indicating the matching instrument model, the warranty clause should be paid; most manufacturers have the original xenon lamp as a consumable item without any warranty, but Heraeus provides 1000 hours or 2000 hours of use and half year storage period quality assurance.
Q6: How should the xenon lamp be installed?
A6: The instruction manual for the replacement of the xenon lamp will be used in the instruction manual of the instrument. Please read it carefully. At the same time, it should be noted that the glass case of the xenon lamp cannot be directly touched by hand. Please wear gloves and install it.
Q7: Why does the newly installed xenon lamp show off?
A7: The current instrument design is often that the user cannot directly distinguish whether the xenon lamp is lit by the naked eye, but only judged by the energy value displayed by the instrument software; firstly, the fault caused by the instrument signal line and the power source should be excluded, and then the 应该 should be excluded. Lamp power board failure.
Q8: Is the newly purchased xenon lamp a bad stability?
A8: New xenon lamps often need to be used for 16 hours to obtain the best stability and energy; if it does not affect the effect, please use 16 hours later to judge. At the same time, the interference caused by the column should also be excluded.
Q9: Is the newly purchased xenon lamp enough?
A9: The principle is the same as A8.
Q10: Why does the xenon lamp suddenly go out in use?
A10: Due to some old instruments, power supply design defects or power supply electrical performance aging over time, the xenon lamp suddenly extinguishes during use. The mains voltage should be excluded from over-limit or drastic changes, and the UPS should be configured as appropriate.
Q11: Why is the decline in xenon lamp energy different?
A11: The energy distribution of xenon lamp is uneven. The energy of 200nm is about 2.5 times of the energy of 254nm, and the energy of 200nm wavelength is about 40% after 2000 hours of use. At this time, the energy of 254nm wavelength only drops by 25% (Longlife d2lamp).
