Most of the newly purchased four-wheelers in rural areas are battery-operated. Once farmers fail in the fields, they are in no help. Several troubleshooting methods are: First, if the car motor does not turn after the vehicle is closed, but there are squeaks, nine out of eight is caused by poor contact with the battery pole poles. As long as the electric bottle can be cleaned up, in particular, the iron line should be re-installed once. It is best to receive the line from the body. Do not attempt to receive the cover. Second, if the four-wheeler is not charging, it may be that the regulator is broken. Just put the two regulators together, such as charging, to temporarily use them, and then replace them when they return home. Third, if the driving lights suddenly go off at night, it is a bad connection or the switch insurance is broken. It is safe to get home by temporarily connecting the positive electrode to the bulb to make it light up. Fourth, the battery to determine the simple fault: Use a charger to charge the battery, open the battery cover for half an hour to observe, if there are bubbles in each bubble of the same bubble that proves that the battery does not lose power. If one or two hours each battery does not bubble battery is depleted, you need to charge to the bubble for two hours. If the battery is charged in a format or two bubbles are present, it is a bad sign. If the battery is charged with a gas bubble and other cells have bubbles, then this cell has a short circuit, the battery can not get off. (mountain sea)
PC Board Venlo Greenhouse
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.
