Lifting column, also known as lifting ground column, lifting road pile, anti-collision road pile, hydraulic lifting column, isolation pile, etc. It is also relatively common in our present life, especially in places such as schools, communities, and in front of government and enterprise units. After years of application and development, lifting columns have now expanded into various styles. Its main categories are:
1. Pneumatic full-automatic lifting column: Air is used as the driving medium, and the external pneumatic power unit drives the column to rise and fall.
2. Hydraulic automatic lifting column: hydraulic oil is used as the driving medium. There are two control methods, namely, the external hydraulic power unit (the driving part is separated from the cylinder) or the internal hydraulic unit power unit (the driving part is placed in the cylinder) to drive the cylinder up and down.
3. Electromechanical fully automatic lifting: the lifting of the cylinder is driven by the built-in motor of the cylinder.
Semi-automatic lifting column: The ascending process is driven by the built-in power unit of the column, and it is completed by human power when descending.
4. Lifting type lifting column: the lifting process requires manual lifting to complete, and it depends on the weight of the column body when descending.
5. Movable lifting column: the column and the base are separated, and the column can be retracted when it does not need to control.
6. Fixed column: The column is directly fixed to the road surface.
Different types of lifting columns have different adaptation places. For example, some places with high security levels, such as military bases, need to use anti-terrorism level lifting columns. The thickness of the column generally needs to be more than 12mm. The general civilian-level lifting column is 3-6mm, which is suitable for vehicle access control places with large traffic flow and medium safety requirements. Widely used in banks, government agencies, research and development centers, power stations, highways, industrial parks, villas, office buildings, boutiques, pedestrian streets and other places.
In addition to the classification according to the working principle of the lifting column, it can also be classified according to the application method of the lifting column!
1. Automatic lifting column
Lifting and lowering of lifting columns can be done automatically through legally authorized information. Full-automatic door lifting columns are also the main equipment of various manufacturers of lifting column products. Generally, they are used in places where there are frequent takeoffs and landings, and there are certain security forces around them.
2. Semi-automatic lifting column
Use the manual key to lock or release the lifting column. When the device is in the raised state, the artificial foot will be stepped down after the key is released, and it will be automatically locked when it is in place, and will automatically be raised after the key is released again. In places that rarely need to take off and land. Or there is no place with security forces around. The main reason is that the semi-automatic saving construction cost is low, and the second is because the semi-automatic lifting column does not have a control board or a control cabinet and has high anti-theft security. For example, pedestrian streets, squares and other places can be selected. In addition, some wide entrances and exits can be used with automatic lifting columns.
3. Fixed road pile
The part on the road surface has the same appearance and materials as the fully automatic / semi-automatic lifting column, but it cannot move. Mainly used with fully automatic / semi-automatic lifting columns.
Hydrofluoroether is a general term for an ether compound containing a hetero atom such as an oxygen atom in the molecule. It has a promising compound with zero ozone digestion value (ODP), low global greenhouse potential (GWP), and atmospheric retention. The short time is considered a new type of ideal chlorofluorocarbon (CFC) alternative. In addition to excellent environmental properties, hydrofluoroethers are also characterized by low toxicity, non-corrosive, non-combustible, no fumes, easy to store and transport, and have unparalleled advantages over other alternatives.
