With the continuous progress of the society and the development of science, energy conservation has become more and more concerned about the topic, all industries in all countries are taking active and effective measures to save energy. This article will tell you about the energy saving method of air compressor.
1. Solutions to air compressor leakage and gas use
According to the authority inspection, the electric energy consumed by the air compressor is only 10% into the compressed air, and the remaining 90% is converted into heat energy. Thus, the compressed air is ten times more expensive than the electricity fee, but we often ignore this point. In most factories, the sound of air leakage can be heard everywhere, but there is no one at all. If we solve the problem of leakage, we can save a lot of energy. Therefore, when we hear the leakage, we should take appropriate measures in time. Some factories have great misunderstandings in the way of using gas. For example, in line plate manufacturers, most electroplating lines should use vibration to increase the ability to electroplating on small holes. Some manufacturers prefer to use gas vibration to achieve this purpose.
Therefore, the energy saving of air compressors should avoid improper gas consumption while dealing with the problem of leakage in time.
Two. Energy saving retrofit air compressor
There are mainly three ways to save energy for air compressor, 1. frequency conversion and speed regulation.
The frequency conversion speed regulation method is adopted to reduce the shaft power output of the air compressor motor. Before the transformation, the pressure of the air compressor reached the set pressure, that is, it will automatically unload; after the transformation, the air compressor does not discharge, but by reducing the speed to reduce the gas production in the compressor, and maintain the minimum pressure needed in the gas network. There are two places to save energy:
(1) reduce the power consumption caused by the sudden change of the compressor from unloading state to loading state.
(2) the running frequency of the motor is reduced to below the power frequency, so that the output power of the motor shaft is reduced. The above two ways all reduce the energy consumption of the air compressor in the operation process, but the air compressor produces so much heat in the working process to let it distribute white to the air, but it has not received the universal attention of the user for a long time, which can not be said to be a great regret.
2. centralized control mode
The centralized control mode is adopted for multiple air compressor. According to the air condition, the number of operating units of the air compressor is automatically controlled. Before the transformation, the number of the opening of the air compressor is fixed.
(1) if the volume of gas is further reduced, the air compressor with good performance will stop automatically. In the case of (1), air compressors consume energy even under unloading conditions. After transformation, the air compressor with the corresponding number of units can be stopped, and the number of operating units is reduced.
(2) when the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.
Heat recovery of 3. air compressor
Air compressor heat recovery is a very environmentally friendly way to save energy.
Working principle of heat recovery unit
The high temperature oil of the air compressor passes the heat to the cooling water through the superheat exchanger, and the cooling water is heated to the heat preservation bucket, which can achieve the purpose of heat recovery.
