Evaluating the Stability of Tunnel Washer Systems: The Hydraulic System, Oil Cylinder, and Water Extraction Basket's Effects on Water Extraction Press

The water extraction press is the core equipment of the tunnel washer system, and its stability affects the entire system's operation. Let's explore the influence of the hydraulic system, oil cylinder, and water extraction basket on the stability of the water extraction press.

The Hydraulic System

The hydraulic system is the heart of the water extraction press. The stability of the press's pressure is reflected in the hydraulic system. The stroke of the press cylinder, each pressing action, the response speed of the main cylinder, and the accuracy of pressure control are all determined by the hydraulic system. An unstable system not only has a high failure rate but also increases the linen damage rate.

The Brand and Diameter of the Oil Cylinder

The pressure of the water bag is related to two factors: the diameter of the oil cylinder and the pressure of the hydraulic system. When the hydraulic system output pressure is the same, a larger cylinder diameter results in higher pressure during water extraction, while a smaller diameter results in lower pressure. Similarly, when the water bag pressure is the same, a smaller cylinder diameter requires higher pressure from the hydraulic system, demanding more from it.

CLM's heavy-duty water extraction press features a large cylinder diameter of 410 mm and high-quality cylinders and seals, increasing the water bag pressure while reducing the hydraulic system's operational intensity.

The Water Extraction Basket

The quality of the water extraction basket affects the linen damage rate and the water bag's lifespan. When wet linen falls from the tunnel washer into the basket from over one meter high, the impact is significant. If the basket's strength is insufficient, it may deform slightly over time. This deformation misaligns the water bag and the basket, increasing friction and causing damage to the water bag, which is expensive to replace. Misalignment also traps linen between the bag and the basket, increasing damage rates. Additionally, improper design of the gap between the basket and the water bag or misalignment of the oil cylinder and the basket can also cause linen damage.

CLM's water extraction basket is made from 30-mm-thick stainless steel, welded after rolling, heat-treated, ground, and mirror-polished to 26 mm, ensuring it does not deform, eliminating gaps, and preventing linen damage.

CLM's water extraction press features a heavy-duty structure, stable hydraulic system, high-quality oil cylinders, and precisely manufactured water extraction baskets, achieving a 50% dewatering rate for towels and a linen damage rate below 0.03%, creating greater value for laundry factories.
