The selection of air compressor equipment requires high-efficiency compressors. In view of the gas consumption in enterprise production, the use of gas during peak and trough periods needs to be considered. Variable working conditions can be adopted and permanent magnet frequency conversion screw air compressor can be adopted, which is beneficial to energy saving.
At present, the permanent magnet motor of the domestic permanent magnet frequency conversion screw air compressor is more than 10% energy-saving than the general motor, has the advantages of constant pressure air, does not cause waste of pressure difference, uses how much air to blow, does not need to add and unload, etc. More than 30% energy saving than ordinary air compressor. Frequency conversion production gas is especially suitable for modern production and manufacturing. Centrifuge units can also be used for units with large gas consumption, so that large flow can alleviate the problem of insufficient peak gas consumption.
Screw air compressor
the main rotor diameter is large, and the auxiliary rotor diameter is small. The teeth form a spiral and the two mesh with each other. The two ends of the main and auxiliary rotors are respectively supported and positioned by bearings. When working, the motor directly takes the main rotor through the coupling (or belt). Because the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together. The coolant is directly sprayed into the meshing part of the rotor from the nozzle at the lower part of the compressor casing, and mixed with air to take away the heat generated by compression to achieve the cooling effect. At the same time, a liquid film is formed to prevent direct contact between metal and metal between rotors and to close the gap between rotors and housings. The injected coolant can also reduce the noise generated by high-speed compression.
Since users want to save money, we should persuade them along the way of saving money. Everyone does not know whether to pay attention to overcurrent when maintaining the machine. Generally, the current difference before and after maintenance will be 5 ~ 15%(7 ~ 10% is the mainstream). This means that the electricity wasted by delaying maintenance for 500 hours is enough for one maintenance, and the longer the delay, the greater the difference in current. This is because the air compressor has been operated after a round of maintenance cycle, and a lot of dust and carbon deposits have been adsorbed on the oil surface. If the maintenance is postponed, the dust and carbon deposits on the oil surface will increase. In addition, after a round of maintenance cycle operation, the aging speed of lubricating oil will be accelerated, and the speed of carbon deposition will be geometrically doubled. In addition, if the air filter is not replaced in time after a round of maintenance cycle operation, the suction resistance will become larger and larger, which will also reduce the energy efficiency of the air compressor.
The soft start and frequency conversion start of screw air compressor are two different starting methods, and there are significant differences in the starting principle, functional characteristics and application effect. The following is a detailed comparison of these two start methods: 1. start principle Soft start principle:
In scientific experiments and research, stable and reliable air compressor is one of the indispensable equipment. As a leader in the air compressor industry, Shanghai Granklin Group provides a variety of efficient and safe products for the laboratory with its excellent product quality and advanced technology.
The inspection cycle of the air compressor needs to be considered according to various factors such as equipment type, frequency of use, working environment and manufacturer's recommendations. The following is some detailed information about the air compressor inspection cycle: 1. comprehensive inspection cycle according to industry standards
Compressed air pressure and flow requirements of pharmaceutical industry and adaptability of water-lubricated single screw air compressor 1. Compressed air pressure requirements of pharmaceutical industry The demand for compressed air pressure of pharmaceutical production varies from process to process, and the adaptation range should be selected according to the actual scene: often
The comparison of the durability of oil-free air compressors and oil-free air compressors is a complex issue because it is affected by many factors, including equipment quality, maintenance, and use environment. In general, there is no clear distinction between the two in terms of durability, but rather each.
There are significant differences between oil-free and oil-injection machines in many aspects: Operating principle: oil-free oil-free lubrication technology uses oil-free lubrication technology and will not inject oil into the air when compressing air. The fuel injection machine will inject fuel into the air during the compression process to achieve gas cooling of the rotor,
Whether the air compressor needs water depends on its cooling method, which is mainly divided into the following two categories: 1. water-cooled air compressor needs water source, and the compressor is cooled by water circulation, which is suitable for the following scenarios: large factories: large gas production, stable cooling is required. High temperature environment: such as metallurgy, steel line
The oil content standard of compressed air usually varies according to different industries and applications. The following are some common standards and situations: 1. to the international standard ISO 8573-1 Part 2: ISO 8573 standard divides the oil in compressed air into multiple parts, etc.
The role of explosion-proof screw air compressor is to supply air normally in dangerous environment while ensuring that it will not become the fuse of explosion. Water-lubricated air compressor is born without the flammable factor of oil, which is more reassuring than traditional oil-lubricated machines in explosion-proof scenes, and daily maintenance is simpler.
In the air separation (air separation) system, the air compressor is one of the core equipment, which is used to compress the air to the required high pressure for subsequent cooling, purification and separation processes. There are various types of air compressors used in air separation, according to the working principle, structural characteristics and application requirements.
