The tunnel washer system consists of a loading conveyor, tunnel washer, press, shuttle conveyor, and dryer, forming a complete system. It is a primary production tool for many medium- and large-scale laundry factories. The stability of the entire system is crucial for the timely completion of production and ensuring washing quality. To determine if this system can support long-term, high-intensity operation, we need to evaluate the stability of each individual component.
Evaluating the Stability of Tunnel Washers
Today, let’s explore how to assess the stability of tunnel washers.
Structural Design and Gravity Support
Taking the CLM 60 kg 16-compartment tunnel washer as an example, the equipment length is nearly 14 meters, and the total weight during washing exceeds 10 tons. The swing frequency during washing is 10–11 times per minute, with a swing angle of 220-230 degrees. The drum bears significant load and torque, with the maximum stress point in the middle of the inner drum.
To ensure even force distribution within the inner drum, CLM's tunnel washers with 14 or more compartments use a three-point support design. Each end of the inner drum has a set of support wheels, with an additional set of auxiliary support wheels in the middle, ensuring even force distribution. This three-point support design also prevents deformation during transportation and relocation.
Structurally, the CLM 16-compartment tunnel washer features a heavy-duty design. The main frame is made of H-shaped steel. The transmission system is located at the front end of the inner drum, with the main motor fixed on the base, driving the inner drum to rotate left and right through a chain, requiring a high-strength base frame. This design ensures the high stability of the entire equipment.
In contrast, most tunnel washers of the same specification on the market use a lightweight structure with a two-point support design. Lightweight mainframes typically use square tubes or channel steel, and the inner drum is only supported at both ends, with the middle suspended. This structure is prone to deformation, water seal leakage, or even drum fracture under long-term heavy-load operation, making maintenance very challenging.
Heavy-Duty Design vs. Lightweight Design
The choice between a heavy-duty and a lightweight design impacts the stability and longevity of the tunnel washer. Heavy-duty designs, like those used by CLM, offer better support and stability, reducing the risk of deformation and breakdown. The use of H-shaped steel in the main frame enhances durability and provides a solid foundation for the transmission system. This is crucial for maintaining the integrity of the washer under high-stress conditions.
Conversely, lightweight designs, often found in other tunnel washers, may use materials like square tubes or channel steel, which do not offer the same level of support. The two-point support system can lead to uneven force distribution, increasing the likelihood of structural issues over time. This can result in higher maintenance costs and potential downtime, affecting overall productivity.
Future Considerations for Tunnel Washers
The stability of a tunnel washer depends on various factors, including the quality of materials used for the inner drum and anti-corrosion technology. Future articles will delve into these aspects to provide a comprehensive understanding of how to ensure long-term stability and efficiency in tunnel washing systems.
Conclusion
Ensuring the stability of each component in a tunnel washer system is essential for maintaining high-efficiency laundry operations. By carefully evaluating the structural design, material quality, and performance features of each machine, laundry factories can ensure long-term stability and efficiency, reducing downtime and enhancing overall productivity.
