The stable rising and landing of the hydraulic lifting platform is due to the effectiveness of the frequency converter. Its infinite control of the motor and diesel engine speed of the hydraulic lifting platform ensures stability and comfort throughout the entire lifting process. But this is not the benefit of using frequency converters for hydraulic lifting platforms.
1、 Introduction:
The DC frequency converter (Variable frequency Drive) is equipped with a unique hydraulic lifting platform system software, integrating it with contemporary lifting systems. This system software includes a mechanical equipment braking system control with a unique design scheme for the hydraulic lifting platform. It is necessary for the hydraulic lifting platform to maintain smooth operation. In different situations, the brake system control can be set to on/off to consider the different regulations of the motor and control system software. This system software can be used for motor control of CX and NX series products in open-loop or closed-loop control. CX series products must be equipped with CX107OPT card during closed-loop control, while NX series products must be equipped with NXOPTA4 or NXOPTA5 card.
Frequency converters are beneficial for user applications, as users only need to input speed and instantaneous speed, while other values are calculated by the frequency converter. Unlike other frequency converters, it can automatically calculate the speed ratio and has a large load working capacity. Due to the ability of small and medium-sized frequency converters to solve long-term loads in a short period of time, it can prevent excessive capacity of the frequency converter.
The core concept of new product development is particularly important for all new technology enterprises. High quality is also closely related to the two. In terms of achieving success, the key is to provide users with practical solutions that are relevant to their actual situation. Users and requirements are important for elevator manufacturers.
The key to providing users with practical solutions depends on the FC11313 engineering project using specialized tools for programming. It complies with the IEC11313 standard and can be used to customize the control logic and main parameters of frequency converters.
2、 Advantages
1. Ensure the safe operation of the hydraulic lifting platform
Hydraulic lifting platforms include various types of electrical equipment that are not easily noticed by passengers, but are also crucial for their function. Sometimes this type of machinery and equipment may experience common malfunctions, but even in the event of a power outage, it is not easy to terminate the operation. If the built-in rechargeable battery is powered by a frequency converter system, it can prevent the elevator from stopping between two buildings, making it less likely for passengers to be locked in the elevator and safely reaching nearby buildings.
Another key aspect is to allow the elevator to stop at a level with the building every time, which makes it very easy and safe for disabled wheelchairs, strollers, elderly people with disabilities and their canes to enter and exit the elevator.
2. The application of CXR on hydraulic lifting platforms effectively saves electricity and energy
Applying a frequency converter on an elevator can save resources as it can control the elevator's lift speed. CXR is particularly suitable for elevators, as it has developed a trend particularly in elevators that require the replacement of braking systems in accordance with regulations. CXR can feed back electromagnetic energy without pulse current to the power grid. After the frequency converter replaces the braking system, the rate of all system software can be significantly improved.
Conclusion: The use of DC frequency converters is gradually becoming more common, and the application of frequency converters on lifting platforms has improved the overall characteristics of machinery and equipment, promoting the widespread use of high-tech combined with practical applications.
