Tooth surface wear is a common problem that plagues users and manufacturers during the operation of gear pumps. During prolonged operation, conventional gear pumps experience relative sliding between tooth surfaces that inevitably causes scratches, wear, and even cracks. This not only reduces pumping efficiency but can also lead to complete pump failure, resulting in increased downtime and maintenance costs. However, the YCB series horizontal gear pumps fundamentally resolve the issue of tooth surface wear through specialized manufacturing processes and innovative tooth surface design.
The wear in traditional involute gear pumps stems from the inevitable relative sliding friction that occurs during meshing, compounded by factors such as uneven lubrication, fluid slugging, and contamination. These factors make the gears more susceptible to wear and spalling, which directly shortens the equipment’s service life and reduces pumping efficiency. YCB gear oil pump effectively addresses gear surface wear by employing a dual-arc sine curve composite tooth profile that fundamentally alters the tooth profile curve. This design ensures that, during operation, the speeds of the driving and driven gears at the meshing point are essentially consistent, eliminating pure rolling contact along the tooth profile and preventing relative sliding between the tooth surfaces, thereby cutting off friction at its source. This not only eliminates wear caused by sliding friction but also fundamentally eliminates the fluid entrapment phenomenon common in involute pumps, preventing additional damage to the tooth surfaces caused by fluid pressure surges.
The gears in this equipment are made from high-quality materials and undergo precision forging and surface heat treatment processes to achieve both sufficient toughness and high surface hardness. Meanwhile, high-precision machining ensures that the gear tooth profiles meet exacting standards, thereby preventing abnormal wear caused by tooth profile errors. The result is that the gears can effectively resist abrasive wear, adhesive wear, and fatigue wear even under high-load, high-speed operating conditions, thereby fundamentally extending both the service life of the gears and the overall equipment lifespan. YCB series circular arc gears are capable of self-lubrication using the conveyed medium, such as lubricating oil or fuel, to form a stable hydrodynamic oil film in the gear meshing zone, thereby isolating the metal surfaces of the gear teeth and further reducing the risk of wear. Furthermore, the shaft ends of this equipment utilize mechanical seals and other methods to effectively prevent external contaminants from entering the pump chamber, thereby avoiding damage to the gear surfaces caused by foreign abrasives. On the other hand, the equipment’s well-designed pump housing structure also reduces the likelihood of solid particles and impurities in the medium becoming trapped on the gear surfaces, thereby lowering the probability of abrasive wear. YCB gear oil pump addresses gear surface wear during operation through a combination of features, including a specialized gear-tooth design, precision heat treatment, and self-lubricating capabilities. This not only enhances the gears’ wear resistance to some extent but also fundamentally resolves the wear commonly associated with traditional gear surfaces. As a result, it effectively extends the service life of both the gears and the equipment, improves conveying efficiency and operational reliability, and serves as a more efficient and reliable solution.
