Oil-free screw air compressor for sale | Henan Haijie Technology

Oil-free screw air compressor for sale | Henan Haijie Technology adjusts the value at the adjusting nut of the proportional valve on the unloading valve). , The internal pressure of the unit is positive. The internal pressure of the unit should be between .~. Correction method: This pressure value should be carried out when the unit is unloaded and running. The value should be adjusted on the adjusting nut of the minimum pressure valve. In order to facilitate reading of the set value, a 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 they do not have this function, 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. If the temperature is greater than this range, it means there is insufficient oil, the oil line is blocked, or the temperature control valve is not fully opened. This needs to be checked. Check whether the oil filter and temperature control valve are normal. If none of the above are found, 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 kinetic energy of the gas molecules is converted into the pressure energy of the gas, thereby increasing the pressure of the compressed air. At present, there are many types of air compressors in the domestic market. The more common ones include screw air compressors, centrifugal air compressors, etc. They are distinguished according to air output, power and other factors. The working principle of the centrifugal air compressor is to work on the gas through the impeller, and convert the mechanical energy into gas pressure energy by using the centrifugal boosting effect and the deceleration and pressure expansion effect in the flow channel of the impeller and diffuser. As we all know, high-quality centrifugal air compressor accessories are the basis for ensuring the normal operation of air compressor equipment. Can you tell whether the accessories selected by the service provider are genuine during after-sales maintenance of the centrifugal air compressor? For example, there are many purchase channels at present, but they are nothing more than two aspects. One is to import directly from abroad, and the other is to purchase air compressor parts from dealers. Air compressor parts are imported directly from foreign complete machine factories and parts supporting factories. The quality is guaranteed. If the air compressor parts are purchased from a dealer or re-exported from Hong Kong and Macao, they must be identified according to the above method. In addition, all air compressor parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. If you purchase air compressor parts from an imported company, you can ask them to show the above procedures. Otherwise, it can be judged as non-imported genuine products. In addition, when identifying the packaging of imported air compressor parts, you should also pay attention to the fact that engineering air compressors and air compressor manufacturers have their own professional supporting factory parts suppliers.
