- Product Introduction
Products Description
About Bollards
Pneumatic - driven: Pneumatic - driven lifting columns operate using compressed air. A compressor generates the compressed air, which is then directed to push the column. The most significant advantage of pneumatic - driven columns is their extremely fast response speed. They can be deployed in areas where quick access control is required, such as emergency vehicle entrances at hospitals. In case of an incoming ambulance, the columns can be lowered rapidly to allow unhindered passage.
Electric - driven: Electric - driven columns utilize electric motors. These motors can drive screws or chains to achieve the vertical movement of the column. They are relatively energy - efficient compared to hydraulic - driven ones, as they do not require the continuous operation of a high - power pump. They are also easy to maintain, with fewer complex mechanical parts compared to hydraulic systems. This makes them a popular choice for locations where energy conservation and easy maintenance are key factors, like some modern office buildings.
Working Principle
Hydraulic - driven: As mentioned before, a hydraulic pump is the heart of the system. When activated, the pump forces hydraulic oil into a cylinder. The pressure of the oil against the piston inside the cylinder creates a force that moves the piston rod. As the piston rod extends or retracts, the lifting column attached to it rises or falls. The rate of oil flow can be adjusted to control the speed of the column's movement, and valves are used to regulate the pressure and direction of the oil flow.
Pneumatic - driven: Compressed air is stored in a reservoir. When the system is triggered, a solenoid valve opens, allowing the compressed air to enter the cylinder. The air pressure acts on a piston, which is connected to the lifting column. As the piston moves, the column is either raised or lowered. The speed of the column's movement can be adjusted by controlling the flow rate of the compressed air, usually through a flow - control valve.
Electric - driven: Electric motors are connected to a reduction gearbox to increase the torque. The output shaft of the gearbox is connected to a screw or a chain mechanism. In a screw - driven system, as the motor rotates the screw, a nut on the screw moves along its length. The nut is attached to the column, causing it to rise or fall. In a chain - driven system, the motor rotates a sprocket, which in turn moves a chain. The chain is connected to the column, and as the chain moves, the column is lifted or lowered.
