Centrifugal air compressor sealing package | Shandong Atlas oil-free screw compressor calibration method: The pressure value should be performed when the unit is unloaded and running. The value is adjusted on the adjusting nut of the minimum pressure valve for easy reading. To set the value, the pressure detection point should be taken before the minimum pressure valve and a pressure gauge should be installed (some microcomputer controllers have an internal pressure parameter display function, if not, a pressure gauge should be installed before the minimum pressure valve). The temperature in the north is gradually rising, entering the period of spring and summer. Before the Qingming Festival, centrifugal air compressor users are actively preparing for machinery cleaning, adding lubricating oil, etc., in order to avoid accidents caused by high temperatures in summer. Because the high temperature of the centrifugal air compressor will continue to increase as the room temperature increases, so how to solve the problem of high temperature alarm of the air compressor? The centrifugal air compressor can generate a lot of heat when it is working. If the temperature of the machine room is within the specified range and the oil level is normal, then first determine whether the temperature measuring element of the machine is normal. The check method is to use another temperature measurement Calibrate the instrument. If there is no problem, check the outlet temperature difference of the oil cooler. Normally, it is between d. If the temperature is greater than this range, it means there is insufficient oil, the oil line is clogged, or the temperature control valve is not fully opened. This is required. Check whether the oil filter and the temperature control valve are normal. If neither of the above is the case, consider whether there is any foreign matter blocking the oil line. Another point is that if the temperature difference is smaller than the normal range, it may be poor heat dissipation. Check whether the water inlet of the water cooler is insufficient, whether the inlet water temperature is too high, whether there is grease inside the cooler, and whether the radiator is too dirty. If the temperature difference is normal, but the machine head is still high, it means that the heat generated by the machine head exceeds the normal range, and you should check whether the machine is operating under overpressure. The last thing you need to pay attention to is to check whether the oil cut-off valve is faulty. The failure of the oil cut-off valve usually manifests itself as jumping when the machine is turned on and the temperature rises linearly. For manufacturers who are choosing centrifugal air compressor after-sales for the first time, how to ensure that after-sales service is in place and avoid secondary consumption, the most important point is to consider whether the cooperative unit has authorization or, in other words, whether it has practical experience, so that it can Inspecting the machine goes directly to the core problem. Here, the editor would like to emphasize the most important point. Whether it is centrifugal air compressor accessories or lubricating oil replacement, whether the operation process is standardized is also a selection criterion.
