First of all, we simply understand the oil-free scroll air compressor
the rotary air compressor is the latest type of air compressor developed in the past two decades. Compared with the traditional air compressor, it has a novel structure, small size, light weight, low noise, long life, stable and continuous gas transmission, A series of excellent technical performances such as easy operation and low maintenance cost are praised as air compressors without maintenance and new revolutionary air compressors in the industry.
Principle
the scroll air compressor is composed of two moving and static scroll plates meshing with each other. In the process of suction, compression and exhaust, the static disc is fixed on the frame, and the moving disc is driven by the eccentric shaft and restricted by the anti-rotation mechanism, and rotates on a plane with a small radius around the center of the static disc base circle. The gas is sucked into the periphery of the static disc through the air filter element. As the eccentric shaft rotates, the gas is combined into several crescent-shaped compression chambers under the engagement of the static and dynamic discs, and is gradually compressed, and then continuously discharged from the axial hole of the central part of the static disc.
Comparison of oil-free scroll air compressor with piston machine and oil-free screw machine:
1. Comparison of piston machine and scroll machine
the power of a single scroll air compressor is 1.5kW, 2.2kW and 3.7kW respectively, which probably corresponds to the piston machine dragging three, six and ten. Through the data analysis after actual operation, it is concluded that the scroll machine has significantly improved the quality (oil, particulate matter), operation life, vibration, noise and other aspects compared with the piston machine, so as to meet the national medical gas standard. Mainly applicable to oral clinics, outpatient department.
2. Comparison of water lubricated screw machine and scroll machine
the water-lubricated screw machine and the multi-head scroll machine are mainly compared with 11kW-30Kw models. This kind of equipment is mainly suitable for oral and Junior College hospitals of a certain scale (the number of dental chairs is more than 30, and some scales are about 200). Most of them use imported water-lubricated screw machines or imported scroll machines, and a small number use frame-type multi-head piston machines.
The price difference between frequency and frequency conversion machines mainly depends on their respective technical characteristics, manufacturing costs and market demand. In general, the frequency converter is more expensive than the power frequency. The following is a detailed analysis of this phenomenon: technical characteristics and manufacturing
Compressed air is widely used in the semiconductor industry, mainly in the following aspects: Cleaning and cooling equipment: Since the tiny particles and moisture in compressed air have been removed, it is very suitable for cleaning the surface and internal of semiconductor equipment
When comparing the price of screw and vortex (also known as vortex or scroll) equipment, it is not possible to generalize which is more expensive, because the price will be affected by many factors. These factors include, but are not limited to, the make, model, power, performance, and city of the device.
As a widely used industrial equipment, air compressor is used by many enterprises. Its main function is to provide compressed air to power various pneumatic tools and machinery. The following are some typical enterprises that need to use air compressors: industrial manufacturing enterprises: in
The oil content of compressed air can be divided according to different standards, including international standard ISO8573, European standard DINISO8573 and other application-specific standards. The following are the oil content levels of compressed air according to these standards:
The standard of compressed air for industrial use mainly relates to the content of solid particles, water vapor and oil in compressed air, as well as other related parameters such as gaseous and microbial requirements. The following is a specific summary of industrial compressed air standards: 1. solid particle content
Professional description of the application scenario of variable frequency screw air compressor in wool spinning enterprises With its advantages of high efficiency and energy saving, stable gas supply and intelligent adjustment, variable frequency screw air compressor has become the key setting for wool spinning enterprises to optimize production process and reduce operating costs.
The role of oil-free air compressors in the chemical industry is mainly reflected in the following aspects: 1. ensure the purity of gas and improve the quality of chemical products. The chemical industry has strict requirements on the purity of compressed air. Oil-free air compressors do not use lubricating oil during operation, avoiding
As the key equipment in industrial production, the reliability and stability of air compressor are very important to ensure the continuity of production process and product quality. Regular maintenance of air compressors is to ensure long-term stable operation, prolong service life, improve energy efficiency and avoid sudden
The maintenance of screw air compressor should follow the "three-level maintenance system" (daily, monthly and annual), and make a plan in combination with the use time, environmental parameters and sensor data. The following are detailed requirements: 1. daily maintenance (daily/per shift) oil level inspection
