，工作压力250psi，流量只有25L/m。 Customer: Liang Gong, there is a customer who wants to find a hydraulic station cooler
with a working pressure of 250psi and a flow rate of only 25L / m. The original cooler was imported and the oil temperature was too high. I wanted to add one more in series to cool down.
Liang: How much is the electrical power of the host of the hydraulic station?
Customer: The factory is not very clear. I only sent a system oil map, and I forward it to you.
Liang: OK, you can check how much traffic he used?
Passenger : 30L / min
Beam: OK, the effect is not good with tandem, AH1012 is enough.
Guest: Liang Gong, does AH1012 have 380v? Is it available?
Customer: The installation effect picture taken by the customer, but the abnormal sound coming from the customer response core will be shown to you first. I'm still following up. You can see it.
Liang: Come and watch the video.
Liang: There is air coming in. The sound must be in the air.
Customer: Is it full of oil?
Liang: Yes, it takes a few more breaths.
Customer: How do we vent this situation?
Liang: Raise the oil return pipe of the air cooler and put more oil on it.
