液压站解决方案
AH, HD series design pressure ≤ 2.0Mp. In the low-power hydraulic station, when using circuit cooling (not recommended), a bypass circuit must be installed to prevent the air cooler from bursting due to high pressure pulses when the system returns abnormally. The design pressure of the AF series is ≤1.0Mp, and it is not resistant to vibration and shock. It is only suitable for the drain cooling of variable vane pumps. [View]

There is a scholar: For a long time, laymen have said that his level is high, but laymen often do not agree (annotation: there is an air cooler manufacturer claiming that my product test pressure is high and high, the oil return pulse will not burst ). The camps on both sides are obvious. Why is there such a clear difference? In my opinion, the reason is that his point of view is often "right" logically, but "wrong" in practice, and the logic and practice deviate.

Guest: Can you provide a question and answer about the calculation of the power of the air cooler? For example, how do we choose an air-cooled model? Is there literature? Technique: Yes, in fact, there are related pages in our manual. Guest: How to calculate the cooling power of the air cooler? Technology: Generally speaking, the selection points are: 1. Calculate the cooling power of the equipment accurately 2. Calculate the return flow (the return flow is not equal to the flow of the pump). Then according to the design manual recommendation, multiply by 2-3 times the flow safety factor. The flow selection of the air cooler is the same as that of the external filter, which is 2 to 3 times the safety factor. 3. Select an air cooler that satisfies both parameters 1 and 2. 4. Air-cooled cooling target oil temperature has the greatest correlation with ambient temperature. The best temperature that can be achieved is: about 10 ° C higher than the ambient temperature.
