The biggest feature of permanent magnet variable frequency air compressor is energy saving. General energy saving effect of 8% and above. It mainly depends on the working conditions and the parameters of the inverter. When the customer's gas pressure is unstable and fluctuates greatly, the energy saving effect is better.
2. Air pressure is stable. As the variable frequency screw air compressor uses the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter, and it can quickly adjust the response when the gas consumption fluctuates greatly.
3, the host and motor integrated shaft transmission efficiency of 100, no coupling, no gear, no belt drive. Permanent magnet motors do not require bearings, maintenance, or lubricant addition, eliminating fault points and reducing maintenance costs. Ordinary asynchronous motors often have faults such as bearing wear and coil burning, and maintenance costs are high.
4. The inverter itself covers the function of soft start. The maximum starting current is within 2 times of the rated current, and the starting impact is very small. Power frequency start is generally more than 6 times the rated current, when the factory power grid capacity is limited, it will cause the air compressor switch trip. Not only the impact on the power grid, but also the impact on the entire mechanical system is greatly reduced.
5, variable flow control ordinary power frequency air compressor can only work in a displacement, and permanent magnet variable frequency air compressor can work in a relatively wide range of displacement. According to the actual gas consumption, the motor speed is automatically adjusted in real time to control the displacement. How much gas is used to produce how much gas, and when the gas consumption is low, the air compressor can be automatically dormant, greatly reducing the loss of energy.
The discharge oil content of screw compressors is usually expressed in ppm(parts per million, parts per million). This is a concentration unit used to describe the proportion of oil in the gas discharged from the compressor. The smaller the ppm value, the oil content in the gas
Air compressor blowing out of the gas with water is a normal phenomenon. The following is a detailed explanation of this phenomenon: The cause of 1. moisture Humidity in the air: The air in its natural state always contains a certain amount of moisture, the so-called humidity. When the air is compressed, this water
It is a relatively common problem for air compressors to spray out water, which is usually caused by the condensation of water vapor in the air into liquid water during the compression process. The following are the possible causes and solutions: possible causes: high ambient humidity: wet
The air compressor of the fermenter shall be equipped with the fermentation process requirements, air compressor performance parameters, system matching and safety and environmental protection requirements. The following are the specific configuration points: 1., the gas consumption required for the fermentation process shall be calculated according to the volume and stirring power of the fermenter.
When the air compressor has serious coking phenomenon, the following measures can be taken to deal with it: 1. replacement of the oil and filter element First, the oil and filter element in the air compressor should be replaced immediately. As the coking substance may have seriously polluted the oil and filter element, it is necessary to replace the new oil and filter element
Analysis of Main Characteristics of Power Frequency Air Compressor As a traditional compressed air equipment, the power frequency air compressor drives the motor through a fixed frequency power supply, and its technical characteristics and application scenarios have significant industry representation. The following from the working principle, core characteristics and frequency conversion machine
The displacement of the 22kw air compressor is not a fixed value, it will be affected by many factors, including the working pressure, speed and design characteristics of the air compressor. Generally speaking, the displacement of the air compressor will decrease with the increase of the working pressure. For example
During the operation of the air compressor, if it is shown to exhaust every few minutes, this behavior is usually called "intermittent exhaust" or "periodic exhaust". This exhaust mode is not the continuous exhaust of the air compressor.
The tin room can be used as an air compressor room under certain conditions, but many factors need to be considered to ensure its applicability, safety and efficiency. First of all, the feasibility of the iron room as an air compressor room depends on whether its design and structure meet the operating requirements of the air compressor.
To choose an air compressor that can meet the demand for 20 cubic meters (or 20 cubic meters) of gas, it is first necessary to clarify whether the 20 cubic meters are required per minute, per hour or other time units. Generally, the air compressor gas production in cubic meters per minute (m & sup3;/min)
