First of all, we simply understand the oil-free scroll air compressor
scroll air compressor is the latest type of air compressor developed in the past two decades. Compared with traditional air compressors, it has novel structure, small size, light weight, low noise, long life, stable and continuous gas transmission, A series of excellent technical performance such as easy operation and low maintenance cost. It is praised by the industry as a new revolutionary air compressor without maintenance.
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.
With the same power, the advantage of water lubricated screw machine is larger than the air volume of scroll machine. The disadvantage is that the requirements for water quality are high, and it is difficult for the hospital to meet the water quality requirements during use, which is easy to cause equipment damage and shutdown. At the same time, the machine needs to be used and equipped. The advantage of scroll machine is multi-head PLC intelligent control, self-adjusting the main machine to work according to the actual gas consumption, without spare machine, the disadvantage is that the operating cost of electricity is higher than that of screw machine.
Comprehensive advantages and disadvantages, more and more on the scale of the oral hospital in the compressed air equipment on the choice of water-lubricated air compressor
Industrial compressed air oil content standards vary according to application fields and industries. The following are industrial compressed air oil content standards based on different standards and specific applications: International Standard ISO 8573: Level 1: Oil content less than 0.01 mg/m & sup3;, Filtration
Oil-free air compressors are widely used in industries with high air quality requirements because of their high purity and cleanliness of the exhaust gas. The following are some of the main application areas of oil-free air compressors: Medical industry: In the medical field, oil-free air compressors are often used in ventilators, anesthesia
Granklin water-lubricated oil-free air compressor-efficient, environmentally friendly, and future choices With the rapid progress of science and technology, production equipment in all walks of life is gradually being upgraded to meet the growing demand for efficiency and environmental protection. In the air compressor market
To judge whether the air compressor is oil-containing or oil-free, you can consider the following aspects: First, you can refer to the product manual or technical specification sheet of the air compressor. These data are usually clearly marked whether the air compressor is oil-containing or oil-free. by reading carefully
The main differences between the suction dryer and the cold dryer are as follows: Working principle: The suction dryer: The moisture in the compressed air is adsorbed by the adsorbent (such as silica gel, activated alumina, etc.) to achieve the drying effect. When the adsorbent is saturated, it needs to be regenerated.
Dry oil-free screw air compressor 1. In terms of reliability, the application of dry oil-free screw air compressor has a long history and the technical scheme is very mature. At present, the internationally renowned compressor manufacturers are using dry screw technology to produce pure oil-free compressed air.
1ppm oil content is a key indicator of compressed air quality control, the specific meaning is as follows: definition analysis ppm(parts per million): means the concentration per million parts, that is, the mass of oil particles contained in the air per million unit volume. 1ppm: equivalent to every cubic meter of air
The power of the air compressor in the workshop varies depending on the specific needs of the workshop, the scale of production, the type of equipment and the frequency of use. Generally speaking, the power range of air compressors for workshops can range from a few kilowatts to hundreds of kilowatts. Below is the car.
Screw air compressor can be divided into frequency conversion and fixed frequency according to whether the frequency of its drive motor is variable. The following is the specific distinction between these two types of air compressors: Variable frequency screw air compressor: Motor frequency is variable: During operation, the motor frequency can be compressed
The oil content at the outlet of the screw air compressor is a key indicator to measure its performance and compressed air quality. The following from the standard range, influencing factors and control methods of three aspects of detailed answers: 1. screw air compressor export oil content of the standard range according to industry standards and systems.
