About: What are the applications of automatic lifting columns in the vehicle access management system? Below, please ask the technical staff of Foshan City Shield Standard Lifting Road Barrier Company to introduce to you, I hope that our introduction can help you better.
1. The cylinder is lowered: after the legal authorization is verified, after the control unit receives the switch signal, the lifting column is driven down, parallel to the road surface, and the vehicle is released. The authorization method can be various methods such as buttons and access control.
2. Cylinder rise: After the legal vehicle passes, the control unit receives the switch signal and drives the lifting column to fully rise. The signal can be given in various ways such as a remote controller, a button, and an access control.
3. Protection: When there is a vehicle staying above the lifting column, the column does not rise. The priority of the protection mode is higher than the priority of the rising command; however, the protection of the passing vehicle cannot be achieved through the protection system such as infrared and ground sensing.
4. Power-off release: After power-off, the channel can be released by lowering the lift column by remote control. The whole system can control the entry and exit of vehicles with normal width passages, and is more suitable for the control of vehicles entering and leaving the wide gate passage. At present, if there is more than 6 meters of passage, there is no good product for the control of vehicle access and entry, and the buried coil type long-distance card reading system is very suitable for wide-channel vehicle access management. When it is not controlled, it is flush with the ground, there is no blockage, there is no plug-in reading head, no camera, and only the lifting column is blocked during the control, which is suitable for strict control.
5. The cost of the automatic lifting column is much higher than that of the gate. In particular, the imported columns are in the form of ten thousand yuan. They are mainly used to control the passage of road vehicles. They are specially designed to prevent non-permitted vehicles from entering the sensitive areas. High practicality, reliability and safety. It is much faster than the telescopic door, and it is much wider than the channel controlled by the gate. The effect can be said to have its unique performance advantage.
A Cylinder Block is the structure which contains the cylinder , plus any cylinder sleeves and coolant passages. In the earliest decades of internal combustion engine development, cylinders were usually cast individually, so cylinder blocks were usually produced individually for each cylinder .
A Cylinder Head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber. This page covers the main function and various designs of cylinder heads, and their causes and symptoms of failure.
The passages in the cylinder head allow air and fuel to flow inside the cylinder while permitting the exhaust gases to flow out of it. The passages are otherwise called ports or tracts. The cylinder head also channels the coolant into the engine block, thereby cooling down the engine components. The cylinder head uses a gasket that aids in preventing water or oil from leaking into the combustion chambers.
