1. When the compressor works at low speed, it can be seen that the heat exchange of the cylinder cooling water basically increases slightly with the increase of the cooling water flow, but the change is not large. The specific power basically decreases gradually with the increase of cooling water flow, indicating that the efficiency of the compressor is gradually increasing in this process.
2. When the compressor is working at medium speed, it is obvious that the excessive cooling water volume causes the heat exchange to decrease, and the specific power gradually increases slightly with the increase of the cooling water flow rate, indicating that the cooling water exceeds the optimal flow rate. The power consumption of the compressor is gradually increasing, and the specific power gradually increases with the increase of the cooling water flow.
3. When the compressor works at a relatively high speed, the heat exchange of the cooling water is relatively large at a small flow rate, but after the optimal flow rate is exceeded, the heat exchange amount decreases significantly. The specific power increases steadily as the cooling water flow increases.

1. The air valve is the heart of the air compressor. The air valve adopts a combined air valve. Features high efficiency and long life
2. There is a shock-resistant pressure gauge and a safety valve device between the unit stages. Once the overpressure is automatically discharged, the safety is ensured.
3. The large and small heads of the main rod adopt special bearings, which have super load capacity, low friction power consumption and long service life.
4. The oil level of the main engine adopts a low oil level switch system, which detects the oil level in time, and stops immediately for protection if there is a shortage of oil.
5. The unit adopts a modular design, which is convenient to form multiple units, which doubles the gas production and is convenient for users to choose.
