Second-hand centrifugal air compressor in stock | Henan Haijie Air Compressor

If the temperature is greater than this range, it means that the oil flow is insufficient, the oil line is blocked, or the temperature control valve is not fully opened. Please check the oil filter. When using an alternative oil filter, consider whether the flow is insufficient. If there is a pre-filter, please check. Some models have oil flow adjustment, please adjust it to the maximum first, check whether the temperature control valve is normal, you can remove the valve core, close one end of the temperature control valve, and force all the oil to pass through the cooler. If the above method fails to solve the problem, you must Consider whether the oil line is blocked by foreign matter. If the temperature difference is smaller than the normal range, it indicates poor heat dissipation. For water-cooled machines, please check whether the incoming water volume is insufficient, whether the incoming water temperature is too high, whether the cooler is scaled, whether there is grease in the cooling system, and for air-cooling, please check whether the radiator is too dirty or not. The cooling fan is abnormal, the air volume is insufficient, if there is an air duct, whether the air duct is blocked, whether the air duct is too long, a relay fan is not added, the relay fan is not turned on, or the relay fan is faulty. Is there grease in the radiator? If the temperature difference is within the normal range but the machine is still high, it means that the calorific value of the machine head exceeds the normal range. You should check whether there is overpressure operation, whether the oil quality is wrong, whether the oil quality is aging, whether there is a problem with the machine head bearing or even end friction. In addition, if there is an oil cut-off valve, check whether the screw air compressor is faulty. If the oil cut-off valve fails, it will usually jump when the machine is turned on and the temperature will rise linearly. Since then, centrifugal air compressors have been successfully developed into the above models, and their good performance in the market has gradually become the mainstream of the market. Currently, the more developed models still have good performance in terms of efficiency. It completely reverses the early concept that centrifugal air compressors are only suitable for large air volumes. Centrifugal air compressors also have some inherent flaws. Its advantage is that it covers a very wide range of air volume, ranging from 1/2 to thousands/, and can be borne by a single machine. The larger the air volume of a single unit, the more the investment cost per unit air volume is low. . Sturdy and durable, the failure rate in long-term continuous operation is extremely low. . The structure is simple, with only a few gears, bearings and blades forming the main compression part. There are very few consumable parts and easy maintenance.
