Shanghai granklin two-stage compression air compressor, our two-stage compression air compressor adopts water-lubricated air compressor head, while saving energy and electricity, we make the whole machine oil-free, gas oil-free, make the gas pure and oil-free, can be applied to medical breathing grade compressed gas.
Permanent magnet frequency conversion + two-stage compression is superior to ordinary power frequency single-stage in energy saving efficiency.
Isothermal graded compression, much more efficient than single-stage compression), permanent magnet motor, permanent magnet variable frequency control
(The motor efficiency is higher than that of asynchronous motor, no no-load power consumption, no over-voltage power consumption, saving energy consumption at startup
save control pressure bandwidth waste energy using constant voltage output)
under certain working conditions, the comprehensive energy saving is as high as 59% compared with ordinary power frequency machine.
Saving energy and money is making money.
Two-stage compressor head efficiency is 17% higher than single-stage compression
using permanent magnet motor, the efficiency is 5-7% higher.
Reduce no-load consumption (saving about 30% on average).
Eliminate excess pressure waste, saving 7-8% efficiency
high reliability, low noise
the two-stage compression screw head reduces the compression ratio, reduces the load of the bearing, improves the life of the head, and is durable.
The permanent magnet synchronous motor has high heat-resistant temperature, does not lose magnetism at high temperature, and has a longer service life.
There is no leakage point in the internal connection of the whole machine. The air filter has a large filtering area and uniform air intake.
The combined water filter element and air filter element are adopted, and the filtering effect is good. Silent box design, the use of composite sound absorption material, low noise.
Quality assurance layer by layer quality inspection, strict quality control
select brand suppliers to control quality from the source.
Total quality management, implementation of lean production
to provide users with suitable high-performance products and services is our aim
1. The possibility of the screw air compressor failing to start the air compressor failing to start causes this problem is much more likely than price, but experienced engineers generally consider the problem from the following aspects: First, whether the fuse is burned out, this is a common question.
Those engaged in the installation, transformation and maintenance of pipelines such as gas storage tanks and other pressure vessel equipment must obtain the corresponding qualification license. Units engaged in installation must have installation qualifications, install in accordance with relevant safety specifications and requirements, and be responsible for the safety and quality of pressure vessels, and strictly implement national safety standards and technical standards.
Single screw air compressor in the selection process is often in order to purchase oil-free air compressor, so in Shanghai to do single screw compressor and oil-free air compressor industry to do better is which? "Shanghai Granklin Group" in the water lubrication oil-free air compressor research and development, production, sales, is a comprehensive production of air compressor enterprises.
View detailsGenerally, the service life of carbon steel itself is not long. In addition to the process of making gas storage tanks, the service life of gas storage tanks is about 10 years, which was generally 7 years before. If it is a simple pressure vessel, it must be replaced after 10 years. If it is fixed
The competitiveness of domestic air compressors in the global market has become stronger and stronger in recent years, thanks to the upgrading of the entire domestic industry. In the past like to buy imported air compressor, different times more and more enterprises began to choose to buy domestic air compressor.
Air compressor is one of the indispensable gas equipment in the production activities of enterprises, which plays a boosting role in the production process. When selecting oil-free screw air compressors, we all want to choose brand and good quality machines, so how can we purchase good quality machines?
Air compressor as the power equipment of production-oriented enterprises, buy the air compressor is not appropriate, the loss is too big, not only the money to buy the air compressor, but also the huge electricity costs, as well as high maintenance costs, more important.
The choice of oil-free series compressor is to choose a clean, reliable and economical gas source, which can greatly promote your business development and ensure your profitability! In many applications, air cleanliness is critical, because even a small drop of oil
Air compressor safety management measures 1, air compressor must have a pressure gauge and safety valve. The pressure gauge must be calibrated regularly. The safety valve and pressure regulator must act reliably, and the operating pressure of the safety valve shall not exceed 1.1 times of the rated pressure. Use of oil
If the permanent magnet air compressor condensate is not discharged for a long time, it will cause rust inside the unit, reduce the effect of lubricating oil, and affect the operation of the air compressor. In summer, it will even cause the air compressor to start and stop constantly. So what is the basic principle of this air compressor?
