column information in the field of hydraulic machinery, relying on friends [20 years] industry deep plowing experience, focus on the output of hydraulic technology innovation, market trends, application cases and other high value content. With the aim of "professional, timely and deep", we provide one-stop information service for engineers, purchasing decision makers and industry researchers, helping users to accurately grasp the pulse of hydraulic technology development.
The hydraulic oil of the stretching hydraulic press is used under high temperature and high pressure. With the passage of time, it will gradually age and deteriorate, and the following phenomena will appear: 1. The state of the oil changes. This refers to oil aging, such as oil color, gas sensitivity and appearance changes. 2, mechanical impurities increase...

The first method relies on the experience of the operator and the field technician of the single-arm hydraulic press. By seeing, sniffing, touching, shaking, etc., it is stipulated that when the oil turns black, it becomes dirty. It becomes cloudy to some extent and is replaced. The second method is to make...

① Set up metal mesh, install a metal inclined mesh at the bottom of the fuel tank, and use 60 mesh mesh to defoam, the best effect. ② Set up a partition to separate the oil return area from the oil suction area of the pump. The oil return is deflected by the partition, and the flow rate is slowed down, which is conducive to bubble separation and oil overflow, but this...
