   功率的计算你可以提供一下答疑吗? 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?
   Technique: Generally speaking, the selection points are:
   1. Calculate the cooling power of the device accurately
   2. Calculate the return flow (the return flow is not equal to the flow of the pump). 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 the air cooler that meets the parameters 1 and 2 at the same time.
   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.
   Customer: I am the person in charge of the product of our company. It was originally selected by the technical department. Now I calculate it by myself. Trouble Lianggong provided some information.
   Technique: You can also check it out at eole71.com. Our official website. There are many materials and cases.
   Customer: We have a machine pump with a flow rate of 283ml / r, actually 410L / min.
   Technique: Yes, the oil cylinder is divided into a rod cavity and a rodless cavity. The speed is the same, so the return oil flow is different.
   Guest: The pressure to return oil is not great!
   Technology: Relative to the working pressure, it is small. But there are pulses in the hydraulic circuit. Sometimes the valve is stuck, or overloaded, or there is a problem with the electronic control. The peak value of the pulse is very large, and a pulse takes only 0.2-0.3 seconds.
   Technique: Mechanical pressure gauges cannot be measured.
   常见的爆烈原因吗? Guest: Is this a common cause of explosion in air coolers ?
   Technique: Of course.
   Guest: Why isn't water cooling easy to burst?
   Technique: The principle is different. Water-cooled is water that enters the copper tube, and oil is outside the copper tube.
   Guest: I see.
   Guest: I always feel that the air cooler is not as good as the water cooling effect.
   Technique: No. When the heating power of the device is equal to the cooling power of the cooler, the effect is the same. So the selection is very important.
   Guest: Thank you.
   Technique: You're welcome.
