For screw compressor design: 1. rational design of the intake and exhaust pipes, dhl reduce pressure loss and leakage inside the tubes; 2. frequency control to achieve capacity adjustment, compared with the conventional type air compressor intake throttle dhl machine, inverter compressor energy savings of up to 30% to 40%; 3. Using direct-coupled motor, reducing mechanical transmission losses, while using dhl efficient permanent magnet synchronous motor. 4. Qin Wei microcomputer control air compressor, reduce the magnitude of the load and unload dhl, dhl minimum guarantee under pressure conditions with gas equipment, reduce exhaust pressure dhl set; 5. Multi-unit control, according to the actual use of air dhl the amount necessary to automatically select the number of units of the machine dhl dhl, thus avoiding unnecessary waste of dhl dhl huge multiple machines at the same time due to the operation. For screw compressors, its shortcomings are the following three points: 1. The high cost: screw compressor rotor tooth surface is a curved space, the need to use a special tool Xianyang compressor, be processed on expensive special equipment. In addition, the screw compressor cylinder machining accuracy also have higher requirements. 2. Not suitable for high pressure applications: Due to the limitations of the rotor and the bearing stiffness and other aspects of life, can only be applied to the screw air compressor and low pressure range, the exhaust pressure is generally not more than 3.0Mpa. 3. Can not be made miniature: screw compressors rely clearance seal gas volume flow is greater than the current general only 0.2m3 / min, screw compressor that has the superior performance. How to avoid the summer heat air compressor air compressor caused the accident in the summer time because there are a lot of accidents caused by high temperatures, but the cause of these failures are almost always hot and operational errors, of which a large part is due to compressor failure did not receive timely treatment caused. Hot summer for the operation of the air compressor is concerned has been a big challenge, so we have been emphasizing the user must create a good working environment ventilation for air compressor system, and when the ambient temperature is too high (over 40 ℃) shutdown rest. In addition, for the operation of the air compressor air compressor price, once found work immediately stop processing abnormalities. After all anomalies must be resolved before they have a reasonable start running again. The most important thing is the need for regular maintenance and check compressor case. In short, you want air compressor stable, long service life, the quality of the equipment itself is a part of everyday use, and reasonable operation is more important part. No matter what brand of air compressor, how good quality, how frequent maintenance to do, if they find fault should be processed immediately, which is responsible for the equipment, but also responsible for business property, it is responsible for the safety of workers, please be sure to keep in mind. Originally summer temperature is high, we recommend you use the air compressor process must pay attention to grasp the temperature, the compressor work place do not put some flammable items.
