There are various types of glass tempering furnaces and their structures are becoming increasingly complex. However, from the perspective of implementing system functions, they mainly include the following subsystems: power system, transmission system, execution system, control system, and control system.
1. Power system of glass tempering furnace
It includes a power machine and its supporting devices, and is the power source of the mechanical system. According to the different properties of energy conversion, it can be divided into primary power machines and secondary power machines. A primary power machine is a machine that converts natural energy (primary energy) into mechanical energy, such as internal combustion engines, steam turbines, water turbines, etc. A secondary power machine is a machine that converts secondary energy sources (such as electrical, hydraulic, and pneumatic) into mechanical energy, such as electric motors, hydraulic motors, and pneumatic motors. The glass tempering furnace uses a secondary power machine, which is the power system of the electric motor.
2. Glass tempering furnace execution system
It includes an executing mechanism and executing components. It is a device that uses mechanical energy to change the nature, state, shape, and position of the work object, or to detect and measure the work. In short, it is used for production or to meet other predetermined requirements. The execution system is usually at the end of the mechanical system, directly in contact with the work object, and its output is also the main output of the mechanical system. Therefore, the performance of the execution system directly affects the performance of the entire system.
3. Transmission system of glass tempering furnace
The transmission system is an intermediate device that transmits the power and motion of a power machine to the execution system. The transmission system has the following main functions: deceleration or acceleration movement, reducing or increasing the speed of the power machine to meet the needs of executing system work. Continuously variable speed movement refers to the force or torque required when continuously variable speed cannot meet the requirements or is not economical. If the working performance of the power machine fully meets the requirements of the execution system, the transmission system can be omitted and the power machine can be directly connected to the execution system.
4. Glass tempering furnace operation and control system
Manipulation and control systems are devices that coordinate the operation of power, transmission, and execution systems and accurately complete the functions of the entire machine. The main difference between the two is that the control system mostly refers to devices that achieve the above requirements through manual operation, including starting, clutch, braking, transmission, reversing, and other devices. A control system refers to a device, such as a servo mechanism or automatic control device, that changes the working parameters or operating status of the control object through manual operation or signals obtained from measuring components, and is controlled by a controller. A good control system can keep the mechanical system in the optimal operating state, improve stability and reliability, and have good economy.
