Description

Technical Field

[0001] The utility model belongs to the field of automatic detection equipment and relates to a device which can simultaneously apply grease to a centrifugal pump ring groove and inject oil into a cylinder hole. Background Art

[0002] In the current industrial and mechanical maintenance field, the lubrication of the cylinder bore and ring groove of the slave pump is a crucial link, which directly affects the operating efficiency, durability and overall performance of mechanical equipment. Traditional lubrication methods, especially the grease injection treatment of the cylinder bore and ring groove of the slave pump, face a series of technical challenges and efficiency bottlenecks.

[0003] First of all, the commonly used grease injection method in the market is to separate the lubrication of the slave pump cylinder bore and the ring groove. This separate operation is not only time-consuming and labor-intensive, but may also lead to insufficient or uneven lubrication. The slave pump cylinder bore is a key component that carries the piston movement, and the uniformity of its internal lubrication is directly related to the smoothness of the piston movement and the sealing effect; and the ring groove is the interface between the piston ring and the cylinder wall, and its lubrication state is the key to affecting the sealing efficiency and reducing wear. Therefore, the separate grease injection method is likely to cause excessive lubrication in some areas while insufficient lubrication in other areas, affecting the overall performance and service life of the equipment.

[0004] Secondly, in the existing technology, the lubrication of the piston ring groove is mostly done by single-point application or simple circular application. This method is difficult to ensure that the inner surface of the ring groove is fully and evenly covered with grease, especially when the ring groove has a complex shape and variable size. A single application strategy is difficult to adapt to different geometric requirements, resulting in a significant reduction in the lubrication effect.

[0005] Furthermore, frequent replacement of tooling for slave pumps of different shapes and sizes is another problem that needs to be solved urgently. The traditional method not only requires the preparation of tooling tools of various specifications, but also increases the time cost for each replacement, which reduces production efficiency. In addition, due to the high degree of specificity of tooling and the lack of versatility and flexibility, once a slave pump of non-standard size or special design is encountered, a customized solution is often required, which undoubtedly further increases the maintenance cost.

[0006] In summary, the existing problems of grease injection technology for the cylinder bore and annular groove of the slave pump mainly include: uneven lubrication, frequent tooling replacement, high cost, poor versatility and flexibility, etc. These technical bottlenecks seriously limit the efficiency and quality of equipment maintenance. An innovative technical solution is urgently needed to overcome the above difficulties and realize an efficient, uniform, cost-effective and adaptable lubrication method for the cylinder bore and annular groove of the slave pump.
