The air-to-air cooler is mainly used in various air, high-humidity air, mixed gas of various media, etc., and the air cooling method is adopted to cool the high-temperature air passing through the heat exchanger.
Applications:Construction machinery engines, automotive engines, air compressors, industrial spray equipment, new energy equipment, electrical equipment, marine equipment, wind power equipment, etc.

(1). Pump leaks.
(2) cartridge hole suction, appear mist: cleaning oil filter, check tubing, pumps.
(3) pump oil pollution: open the gas valve running 1-2 hours or longer, or new oil.
(4). Insufficient fuel, the oil level is too low: fuel.
(5). Oil temperature is too high: Increase the amount of water, reduce the ambient temperature and inhaled gas temperature, eliminate occlusion, poor lubrication.
(6). Exhaust valve damage: for the valve.
(7). Exhaust valve spring damaged: renewal.
(8) parts of the pump wear and tear, there are different sound, power abnormalities: dismantling inspection of the rotating parts.
2 oil spills:
Check the shaft seal, the sealing parts, adjustment or replacement.
3 noise: abnormal noise: check whether foreign objects fall into the pump chamber, bearings, pump drive without damage. Clear, trim, change new.
4 fuel injection: a large number of oil spouts: check the oil level is too high, such as too high, release; oil shield components, anti-injection components, etc. are intact.
5 Vibration: Vibration: Check the base is solid, fastening, the foundation is sufficient. Have bite, stuck in the early signs, adjust.
6 abnormal temperature pump bearing fever: a little loose belt, check whether the smooth flow of oil, cooling water enough. Fuel tank heat, exhaust valve overheating: reduce the inlet pressure, increase the amount of cooling water.
7 bite stuck: check whether foreign objects fall into, parts intact, lubrication is adequate, fuel, oil, pumps.
8 motor current is too large or fuse blown: check the current is too large reason, check the fuse capacity, adjust, change new.
Advantages: Strong corrosion resistance, compact structure, small footprint, and high degree of customization.various air-cooled drive modes, DC motor, AC motor, hydraulic motor, air motor, special explosion-proof motor, etc., better to choose the appropriate drive mode according to industrial environmental factors, without the help of external cooling medium, lower The hardware requirements can be used to cool the oil and ultimately ensure the benign operation of the equipment.
