When there is large-area steam leakage at the mating surface of an Italian Camozzi cylinder, with a gap of approximately 0.50mm, a coating process can be used to reduce the amount of scraping work. Using the cylinder as the anode and the coating tool as the cathode, an electrolytic solution is repeatedly applied to the cylinder mating surface. The thickness of the coating depends on the size of the gap between the cylinder mating surfaces, and the type of coating depends on the cylinder material and the scraping process. Spraying involves heating metal powder to a molten or plastic state using a specialized high-temperature flame spray gun and then spraying it onto the treated cylinder surface to form a coating with the desired properties. Its advantages include simple equipment, convenient operation, strong coating, and the cylinder temperature after spraying is only 70℃-80℃, preventing cylinder deformation. It also provides a heat-resistant, wear-resistant, and corrosion-resistant coating. It is important to note that the cylinder surface must be sanded, degreased, and roughened before coating and spraying. After coating and spraying, the coating layer must be scraped to ensure a tight seal.

Common Faults of Italian Camozzi Cylinders

Problems with Italian Camozzi Cylinders

Italian Camozzi cylinders are cast. After leaving the factory, the cylinders undergo aging treatment to eliminate the internal stress generated during the casting process. If the aging time is too short, the finished cylinder will deform during subsequent operation.

The cylinder is subjected to complex forces during operation. In addition to static loads such as the pressure difference between the inside and outside of the cylinder and the weight of the components inside, it must also withstand the reaction force of steam flowing out of the stationary vanes on the stationary parts, as well as the forces exerted on the cylinder by various connecting pipes under hot and cold conditions. Under the interaction of these forces, the cylinder is prone to plastic deformation, resulting in leakage.

Stress generated during the machining process or after welding repair, if not eliminated by tempering, results in significant residual stress in the Italian Camozzi cylinder, leading to deformation during operation.

During installation or maintenance, due to inadequate maintenance processes and techniques, the expansion clearances of the inner cylinder, cylinder diaphragm, diaphragm sleeve, and steam seal sleeve may be unsuitable, or the expansion clearance of the lug pressure plate may also be unsuitable. This can lead to significant expansion forces after operation, causing cylinder deformation.

The cylinder sealant used may be of poor quality, contain excessive impurities, or be of the wrong type. Hard impurity particles in the cylinder sealant can prevent a tight seal.

Insufficient tightening of the Italian Camozzi cylinder bolts or substandard bolt material. The tightness of the cylinder mating surfaces depends primarily on the bolt tightening force. Thermal stress and high temperatures generated during unit start-up, shutdown, or load adjustments can cause bolt stress relaxation. If the stress is insufficient, the bolt preload will gradually decrease. If the cylinder bolts are of poor quality, they may stretch under thermal stress and cylinder expansion forces during prolonged operation, resulting in plastic deformation or fracture, leading to insufficient tightening and cylinder leakage.

Incorrect tightening sequence of the Italian Camozzi cylinder bolts. When tightening cylinder bolts, they are typically tightened from the center outwards simultaneously, starting from the point of greatest sag or deformation. This shifts the clearance from the point of greatest deformation towards the free ends of the cylinder, gradually eliminating the gap. If tightened from the sides towards the center, the clearance concentrates in the middle, creating an arc-shaped gap at the cylinder mating surface, leading to steam leakage.

Camozzi History

It was in 1964 that three brothers, Attilio, Luigi, and Geromino, began manufacturing industrial automation components in Lumezzañe, a small village in the Lombardy region of northern Italy.

Today, the Cornwallis family continues its history with respect for tradition. Their values ​​and principles are the most important legacy guiding their descendants.

Over 40 years of commitment, dedication, and passion have built a solid foundation for future development and innovation. The Cornwallis story has never lacked passion.
