Whether the installation of the hot coil spring correctly affects the performance and life of the spring
Spring is one of the important components on construction machinery. Poor installation will affect its use and even cause failure of construction machinery.
If foreign matter such as iron filings, burrs, dust, etc. enters the hot coil spring, it will cause noise and vibration during the operation of the spring, and may even damage the raceway and the rolling elements. Therefore, before installing the hot coil spring, it is necessary to ensure the cleaning of the mounting surface and the installation environment.
Lubrication has a very important influence on the operation and life of the spring. Grease is made from base oils, thickeners and additives. The performance of the grease is primarily determined by the base oil. Generally low viscosity base oil is suitable for low temperature and high speed; high viscosity is suitable for high temperature and high load.
The thickener is also related to the lubricating properties, and the water resistance of the thickener determines the water resistance of the grease. In principle, the different greases of the brand cannot be mixed, and even the grease of the same thickener may have a bad influence on each other due to the different additives. The surface of the hot coil spring is coated with anti-rust oil, which must be carefully cleaned with clean gasoline or kerosene, and then cleaned with high quality or high temperature high temperature grease for installation. Fully enclosed springs do not need to be cleaned and refueled.
After the hot coil spring is installed, alignment may cause the spring to experience additional loads, friction and vibration if not carefully aligned. These may accelerate fatigue and reduce the life of the hot coil spring and may damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure.
During use, the basic external conditions of the spring operation are often monitored, such as temperature, vibration and noise measurements. These regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.
During operation, the hot coil spring requires proper relubrication to perfect its performance. The method of hot coil spring lubrication is divided into grease lubrication and oil lubrication. In order to make the hot coil spring function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the spring.
The most important component of the hydraulic pump spring piston pump is the spring. Reducing the negative pressure in the hot coil spring is the basic requirement to prevent water from entering. The load calculation of the angular contact spring. The oil supply maintenance of the locomotive spring is very important.
