Simple installation, different lamps can be equipped, and the number of lamps can be increased or decreased freely. When there is no limit to the number of lamps installed on the track, it can theoretically not exceed the wattage of the transformer power supply.

Rotor pump drive form
Due to its unique working principle, the rotor pump, as a positive displacement rotary pump, is widely used across various industries and can handle a wide range of materials. Whether it's clear water, wastewater, chemical substances, beverages, dairy products, confectionery, or cosmetics, the rotor pump proves to be a versatile solution. As long as the material is in liquid form—whether it's water, viscous fluids, or difficult-to-pump colloids—it can be efficiently transported by a rotor pump, making it a true universal pump.
Although rotor pumps offer excellent delivery performance, their efficiency heavily depends on proper power matching. If the power system isn't well-suited for the application, the pump’s advantages cannot be fully utilized. Therefore, during the selection process, understanding the material properties and power requirements is crucial. This step plays a central role in ensuring optimal performance.
Currently, there are several common power configurations for rotor pumps:
1. **Manual Speed Control Type**: This type features a planetary friction wheel speed control system, allowing for a wide range of speed adjustments and easy operation. However, it has some limitations—such as a relatively high minimum speed and difficulty in reducing speed further. The torque output is also limited, making it more suitable for low-viscosity materials. However, when paired with a gear box, the output torque can be significantly increased, enabling the transport of higher viscosity liquids.
2. **VVVF Type**: This configuration uses a fixed-speed hardened gear transmission combined with an inverter motor that adjusts speed by changing frequency. It allows for smooth, automatic flow control through the frequency converter. Its main advantages include high automation, strong torque output, and flexibility in application. However, it requires an additional drive system, which may increase costs. Despite this, the growing stability and affordability of domestic inverters make this configuration highly appealing. It is often considered the ideal power setup for rotor pumps.
3. **Constant Speed Output Type**: This configuration is commonly used in applications where precise process control is not required. It typically involves a fixed-speed gearbox and standard motor, or a belt-driven deceleration system. The main benefits are its simple structure, ease of use, and minimal maintenance. In certain processes, this setup remains a reliable and cost-effective choice.
In addition to these three, other configurations exist based on specific environmental needs, such as DC electromagnetic speed control, pneumatic transmission, or explosion-proof motor setups. However, the first three are the most commonly used.
Among them, the VVVF type is highly recommended due to its high level of automation, broad applicability, and strong torque output, offering the best value for money. Choosing the right configuration ensures that the rotor pump performs at its best, meeting both operational and economic goals.
