How do bubbles come into being in a hydraulic system?

There are a variety of hazards and effect of hydraulic system is used in the process, including external pollution, internal infection, aging, oil bubble belongs to the hydraulic system of the internal infection, about a possible bubble pollution everyone knows less, then the bubble in oil is produced, what is the harm to the hydraulic system?

Bubble generation

The production of bubbles is related to the invasion of air. The hydraulic oil is produced, stored and transported and the system operates under atmospheric pressure. Therefore, it is unavoidable to contain air in the oil. The air in general oil is called mixed air. It is suspended in oil with a very small spherical bubble. It is mainly formed in two ways:

Mainly through the suction pipe mixed with oil tank and pump, such as tank oil level is too low, the pump suction pipe for a half dew on the oil surface or deep submergence is very shallow, the air can be inhaled; if the oil pipeline leak into the pump, then a lot of air will be inhaled; if the oil return pipe is higher than that of the tank system the oil surface, roll with air into the oil back to the oil system of the high speed jet, again through the oil pump into the system.

Practice has proved that the air dissolved in the oil has no direct influence on the physical properties of oil. But a certain amount of air dissolved in saturated oil flows through the throttle or pump entrance, when the absolute pressure drop to the air separation of oil pressure, oil saturation of the air will be precipitated, micro bubble was dissolved in oil accumulation in bubble appear larger in the system integration.

The production of hydraulic bubbles will cause fatal harm to the system, even endanger the life of the hand and equipment, we need to observe carefully in the usual use process, do a good job of routine maintenance and maintenance of equipment. Since 2003, the construction machinery house has rich experience in the maintenance and repair of machinery and equipment, the accessories are complete and the quality is guaranteed. If there are technical or product problems, please consult Mr. Zhang: 13705210834.

Wonderful recommendation:

Mechanical engineering at Handa steel cooperation will be discussed in Xu
