Both polyurethane buffer and hydraulic buffer are used in vertical transportation systems such as elevators, but there are some differences in their working principles, characteristics and application scenarios. The following is a comparison between polyurethane buffer and hydraulic buffer:
Working principle:
Polyurethane buffer: polyurethane buffer absorbs and disperses impact energy through the elasticity of the material itself. When impact occurs, polyurethane material is compressed and deformed, which converts mechanical energy into heat energy and deformation energy, and transfers the impact force to the whole buffer.
Hydraulic buffer: hydraulic buffer uses internal oil and piston to realize energy absorption and impact mitigation. When impact occurs, the oil generates resistance on the piston through hydraulic damping, which absorbs and dissipates the impact force.
Features:
Polyurethane buffer: it has the characteristics of high elasticity, abrasion resistance and good energy absorption effect. Small volume, light weight, convenient installation and maintenance. It is not affected by ambient temperature and humidity and has good stability.
Hydraulic buffer: It has adjustable damping characteristics and can adjust buffer force and motion speed as needed. Applicable to high-load and high-speed scenarios. However, more complex installation and maintenance are required.
Applicable scenarios:
Polyurethane buffer: suitable for elevator systems with small load, low speed operation, compact space or limited shaft size.
Hydraulic buffer: it is suitable for elevator systems with high speed operation, heavy load and long journey, such as high-rise buildings or heavy industrial equipment.
Generally speaking, polyurethane buffer is commonly used in small elevators or house hold elevators, with the characteristics of small volume, simple installation and good energy absorption. Hydraulic buffer is more suitable for large high-speed elevators or high-load industrial elevators, with adjustable damping characteristics. When selecting, the most suitable buffer type should be determined according to the specific elevator requirements and installation conditions.
Recording and maintenance: After the installation is completed, record the relevant information of the buffer, including the manufacturer, model, installation date, etc. Regularly check and maintain the buffer to ensure its performance and safety.
It should be noted that in the installation process of elevator polyurethane buffer, relevant safety specifications and manufacturer's guidance should be followed. If there is no necessary experience and technical knowledge, it is best to install it by professional elevator technicians. This ensures security and correctness during installation.
