Permanent magnet air compressor has significant advantages in power saving, and its core technical principles and energy efficiency are as follows:
efficient energy conversion:
permanent magnet air compressor used permanent magnet synchronous motor, Its rotor has built-in rare earth permanent magnets, which can generate a stable magnetic field without external excitation current. Compared to the traditional asynchronous motor, eliminating the excitation loss, power factor up to 0.95 or more the utilization rate of electric energy has been significantly improved.
intelligent frequency conversion control:
by frequency converter adjust the motor speed in real time to achieve accurate matching of compressed air output and gas demand. Avoid the traditional air compressor "frequent start and stop" or "constant power operation" caused by energy waste.
integrated design:
screw host and permanent magnet motor share a spindle, no belt, coupling and other transmission components, transmission efficiency of 100 percent further reduce energy loss.
full load operation:
compared with ordinary screw air compressor, permanent magnet frequency conversion model in about 30% power saving at full load.
(Case: After an auto parts factory is used, the monthly electricity bill is reduced by 20%)
partial load operation:
when the gas consumption fluctuates, the energy saving effect is more significant. For example:
Long-term cost-benefit:
although the initial investment is high 2-3 years to recover costs through electricity savings. When combined with government energy-saving subsidies, the payback cycle is shorter.
| Model | energy-saving principle | applicable Scenarios | energy saving effect |
|---|---|---|---|
| permanent magnet variable frequency air compressor | permanent magnet motor + frequency conversion control, output on demand | large fluctuation of gas consumption and long-term high load | 10%-50% (depending on working conditions) |
| ordinary frequency conversion air compressor | variable frequency control, but the motor efficiency is low | gas consumption fluctuates greatly and is sensitive to cost. | 5%-20% |
| power frequency air compressor | fixed speed, no adjustment capability | stable gas consumption, short-term use | no energy saving advantage |
permanent magnet air compressor through efficient energy conversion of permanent magnet synchronous motor and intelligent frequency conversion control it can be realized under most working conditions 10%-50% energy saving effect. It is especially suitable for industrial scenarios with large gas consumption fluctuations and long-term high load. If your business exists high energy consumption of air compressor and high pressure of electricity charge and other problems, upgrading the permanent magnet variable frequency model is the preferred scheme to reduce cost efficiency.
The pressure of the air compressor is normal, mainly depends on the type of air compressor and the specific application requirements. Generally speaking, the pressure range of air compressor can be classified as follows: ordinary air compressor: its output pressure is usually 0.7Mpa to 0.8Mpa
The first maintenance time of the new air compressor may vary according to different situations and manufacturer recommendations. However, in general, the new air compressor should be maintained for the first time after 500 hours of operation. This maintenance is relatively simple, mainly to replace the oil, oil filter and air
The difference between the traditional air compressor and the new air compressor is very big. The different lubrication methods have different requirements for the materials used in the air compressor. The traditional oil-free air compressor head material is lower than the new oil-free air compressor. Oil-free air compressor, especially water lubricated air compressor, must be made of stainless steel. If you encounter a process customization machine, the material requirements are higher. The material selection is determined according to customer needs.
As an important power supply equipment, air compressor has a wide range of applications, covering almost all industrial fields. The following are some of the main application industries: 1. Industrial production of steel, chemical, cement and other industries: These industries require a lot of compressed air
The motor power required for a 20 cubic air compressor is not fixed, it depends on a variety of factors, including working pressure, air compressor brand, model and design technology. Here are some specific reference information: Power range: 20 cubic air compressor power
The oil content of 0.01ppm means that there is only one part of oil in one million parts, that is, the oil content is very low and almost negligible. The ppm(parts per million) is a unit of concentration that expresses parts per million. This low oil content standard
General industrial use: For most industrial production fields, such as auto repair, wood processing, metal processing, etc., the output pressure of the air compressor is usually between 6 ~ 8bar(0.6~0.8MPa). The air flow in this air pressure range is large, which can meet the needs of different degrees of impact, cutting, clamping and so on.
The reason why the gas production of the screw air compressor suddenly fails to keep up may involve many aspects. The following are some possible reasons and corresponding solutions: the possible reason is that the gas consumption of the client is greater than the rated gas volume of the air compressor. The direct feedback from the user is insufficient pressure,
The general range of workshop air pressure is usually set between 0.7MPa and 1.0MPa, which is to ensure the normal operation of equipment and processes. For the machining workshop, the pressure requirement of air pressure is generally between 0.5 and 0.7 MPa (MPa), which can meet
When the air compressor is used in pressure reduction, the change of its flow rate is not a simple process of increase or decrease, but is affected by many factors. First of all, we want to make it clear that the flow of the air compressor usually refers to the air compressor unit time under a certain pressure.
