Energy-saving elevators have been more than 10 years old. Nowadays, the definition of energy-saving elevators has long been defined by various elevator companies and their customers, and it has also been highly valued by relevant laws and regulations. Then China Elevator Lifts Factory will share how to identify the level of energy-saving elevators. ?

The appraisal of energy-saving elevator records can be similar to the five-level system for electrical products, or the five-level system of 3A, AA, A, B, and C. If the communication and AC two-speed elevator is Class C, then the pressure relief valve vortex rod VVVF elevator can be Class B. The output power of the permanent magnet synchronous server is smaller than that of the pressure relief valve scroll server. Therefore, the VVVF elevator with permanent magnet synchronous server is selected. Able to be included in the A level.
1.3A: Permanent magnet synchronous server, VVVF control system, elevator electromagnetic energy generating capacity use more than 40-45%, not immediately impact power grid. This type of elevator is energy-saving and easy to use, and has no impact on the power grid. It is a three-generation energy-saving elevator in the true mature period.

2.AA: Permanent magnet synchronous server, VVVF operation, can use elevator power generation, such as electric energy feedback, but electric energy feedback must meet the standards of the State Grid access license, with electromagnetic energy rectifier for elevators and electromagnetic Can develop the technicality of sine wave smooth solution, but the wrong power network harms the impact. The feedback utilization rate of electric energy is more than 30-20%. This type of elevator enters the third-generation energy-saving elevator line, but it belongs to the third-type energy-saving elevator that enters the door.

3.A: Permanent magnet synchronous server, VVVF operation, large-scale application and promotion of this type of elevator has been in recent years, and the sales volume has gradually increased, the sales market share will increase over the years, the power consumption of the province, and the maintenance of the natural environment It is better than the pressure relief valve scroll elevator. It is the core component of today and will once again increase the market share. This type of elevator is the third generation of energy-saving elevators.

4.B: Pressure relief valve scroll server, operated by VVVF, this type of elevator motor has a higher rated power, but it is more energy-saving than the two-speed communication and communication. It is the second generation of energy-saving elevator technology, but the production is gradually reduced at this stage. There is another market sale on the sales market, which used to be the core component of elevators.

5.B-C: Communication and communication two-speed operation, pressure relief valve, scroll elevator server, plc or older operation method, the key to this type of elevator is the old elevator and the freight elevator.

The above content is organized and shared by China Passenger Elevator Factory, hoping to help those in need.
