With the continuous development and progress of society, energy saving has become a topic of concern to people. All walks of life are taking active and effective energy-saving measures. Nak Electromechanical is committed to the energy-saving transformation of air compressors and the recovery of waste heat from air compressors. In terms of technical engineering, the following experience is shared with everyone:
1. Solve Air Compressor Leakage and Gas Use Mode
according to the authority to test, the air compressor consumes only 10% of the electricity into compressed air, the remaining 90% into heat, it can be seen that compressed air is ten times more expensive than electricity, but often we have ignored this point. In most factories, the sound of air leakage can be heard everywhere, but no one cares at all. If we solve the leakage problem, we will save a lot of energy. Therefore, when we hear the leakage, we should take corresponding measures in time.
There are also some factories in the gas way there is a big misunderstanding, such as circuit board manufacturers, most of the plating line to use vibration to increase the plating capacity of small holes, some manufacturers prefer to use gas vibration to achieve this purpose, as everyone knows, this way than the use of electric vibration to consume more than ten times the power.
Therefore, the energy saving of air compressor, in the timely treatment of air leakage problem, but also to avoid improper gas use.
energy-saving Transformation of 2. Air Compressor
there are two main ways to transform the energy saving of air compressor
1. Frequency conversion speed regulation mode
frequency conversion speed regulation is adopted to reduce the shaft power output of the air compressor motor. Before the transformation, when the pressure of the air compressor reaches the set pressure, it will automatically unload. After the transformation, the air compressor does not unload, but reduces the gas production of the compressor by reducing the speed to maintain the minimum pressure required by the gas network. There are two places where energy can be saved:
(1) Reduce the power consumption caused by the sudden change process of the compressor from the unloading state to the loading state.
(2) The operating frequency of the motor is reduced below the power frequency, so that the output power of the motor shaft is reduced.
The above two methods have reduced the energy consumption of the air compressor in the operation process to varying degrees, but the air compressor generates such a large amount of heat energy in the working process and let it dissipate into the air in vain, but it has not been paid attention to by users for a long time. This cannot be said to be a great regret.
2. Centralized control mode
centralized control mode shall be adopted for multiple air compressors. The number of air compressors running is automatically controlled according to the gas consumption. Before the transformation, the number of air compressors opened is fixed.
(1) If the gas consumption is further reduced, the air compressor with good performance will automatically stop. In the case of (1), the air compressor consumes electric power even when it is unloaded. After the transformation, the corresponding number of air compressors can be stopped, and the number of operating units is reduced, which undoubtedly saves electricity.
(2) When the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.
3. waste heat recovery
air compressor waste heat recovery is a very environmentally friendly energy-saving way. The waste heat recovery of the air compressor is to transfer the heat of the high temperature oil of the air compressor to the cold water through the heat exchange and other technical treatment, and the cold water is heated and flows into the heat preservation storage bucket, so that the purpose of heat recovery can be achieved.
Because 73% of the heat energy of the air compressor is in oil, and the technical treatment and heat exchange of the oil will produce a steady stream of hot water, that is, the air compressor can work at a constant temperature and meet the hot water needed by the factory or life, killing two birds with one stone, and the hot water generated by the waste heat recovery technology of the air compressor does not require any additional cost, which reduces the investment of the factory in manufacturing hot water.
Water lubricated single screw air compressor is an oil-free air compressor series, which uses water as the lubricating medium, which fundamentally solves the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has a simple and compact structure; low speed, vibration and noise
Different brands of low-pressure screw compressors have different prices. Take granklin air compressor as an example. A 7.5kw small oil-based air compressor is about 20,000. This belongs to the middle and high grade, and other brands are either high or low. Of course, there are smaller, 4kw, or piston machines below 7.5kw.
Features of water-lubricated oil-free screw air compressor: completely oil-free air quality water replaces oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality 100 oil-free air without pollution, discharging water without special treatment, and meeting environmental protection requirements.
All the time, is the quotation of high air compressor? Then how to effectively reduce the maintenance cost of air compressor? 1. Ensure the quality of equipment parts The quality of equipment parts can also determine the quality of air compressor, and can improve the performance of equipment.
Oil-free air compressor in the domestic products, with completely independent production capacity of the enterprise "Shanghai Grencklin Group". Localization in the field of oil-free air has improved the global market competitiveness of my country's air compressor products. A steady stream of "oil-free air" supplies domestic mid-to-high-end manufacturing and production gas to produce global commodities.
A good brand is managed by heart, and the screw air compressor depends on the after-sales ability of the manufacturer, and the supply of product accessories is long-term. The first choice for purchasing oil-free air compressors is to make some reputation in the industry, with as many cases as possible and perfect after-sales spare parts.
What are the functions and functions of the screw air compressor control panel (1) Basic operation buttons: 1) Start. Start the air compressor under normal working conditions. 2) Stop. Stop the air compressor under normal working conditions
In the field of air compressor, there are not many manufacturers that can use real frequency conversion motors. Shanghai Granklin Group produces water-lubricated variable frequency air compressors. Through the use of permanent magnet motors and variable frequency controllers, it has achieved the effect of energy saving and emission reduction. General frequency conversion means can suppress frequent loading and unloading of equipment, and can also save a lot of power, improve reliability and reduce noise. If the air compressor uses frequency conversion, it can also stabilize the system pressure.
Air compressor is one of the main mechanical power equipment of many enterprises, and it is very necessary to maintain the safe operation of air compressor. Strict implementation of the air compressor operating procedures will not only help extend the service life of the air compressor, but also ensure the safety of the air compressor operator.
The single screw water lubricated air compressor uses pure water for lubrication and cooling, and the internal parts combination of the body is made of special material medical grade stainless steel, which will never corrode. Dry oil-free air compressor still depends on lubricating oil to cool, the body will produce oil smell.
