How much is a screw air compressor

2026-04-10Views:

Shanghai Granklin (Group) Co., Ltd. (abbreviation: Granklin) is located in Shanghai Baoshan District Robot Industrial Park, covering an area of 60 acres. It is a large-scale energy-saving oil-free screw machine production base in China. The products are widely used in military industry, Food, medicine, machinery and electronics, textile and other industries.

Anyone who has used an air compressor knows that a screw air compressor is a positive displacement gas compressor. It consists of two male and female rotors, a casing, and properly configured intake and exhaust ports at both ends to form a compressed gas working chamber. Then increase the gas pressure by reducing the gas volume and increasing the air density. At present, most factories use screw air compressors, and screw air compressors are becoming more and more common in industrial applications, so more and more people begin to pay attention to the maintenance and repair of screw air compressors in daily use, so the daily maintenance should pay attention to a few points:

granklin Group products are carefully debugged before delivery to customers to ensure the stability and durability of the products. At the same time, technical personnel provide professional technical training to ensure customer after-sales service. Has been to provide customers with screw air compressor machine sales and supporting after-sales service.

operating costs are reduced. The operating cost of a traditional compressor consists of three items: initial purchase cost, maintenance cost and energy cost. Energy costs account for about 77% of compressor operating costs. Through the energy cost is reduced by 43%, coupled with the impact on the equipment after the inverter is started, the maintenance and repair volume is also reduced, so the operating cost will be greatly reduced. Reduce the noise of the air compressor. According to the working conditions of the compressor, after the transformation of frequency conversion speed regulation, the motor running speed is obviously slowed down, so the noise of the air compressor is effectively reduced. Field measurements show that the noise is reduced by about 3 to 7 decibels compared with the original system.

The screw air compressor provided by granklin air compressor is mainly used in industries such as machinery manufacturing, food industry, cement manufacturing, chemical plant, hydropower plant, thermal power plant, forging workshop, foundry workshop, glass factory, steel factory, sheet metal workshop, mine, oil refinery, plastic industry, printing factory, quarry, rubber factory, textile factory and other industries. Granklin can also meet the needs of users in all regions of the country for air compressor accessories and the procurement needs of high-efficiency filters, air system post-processing, various valve maintenance kits and various brands of air compressor lubricants.

the maintenance cost of the permanent magnet variable frequency air compressor is reduced. Due to the energy-saving control system, the software start of the air compressor reduces the electrical impact on the electrical components of the motor, and the starting current is small, which extends the life of the motor contactor. The software start of the air compressor reduces the mechanical impact on the equipment, and the motor bearings, main engine bearings and gear boxes all extend the service life. The permanent magnet variable frequency air compressor reduces production losses. The permanent magnet variable frequency air compressor uses an energy-saving controller and monitors more than 20 parameters, current, voltage, speed, torque, and power consumption. The system has a high degree of intelligence.

Enterprise development spirit: we are never satisfied, strive for brand, improve ourselves and develop continuously. Operating in accordance with the law, scientific management, high-quality service, excellent quality, exquisite technology, and the courage to innovate.

Enterprise brand concept: we are a professional frequency conversion screw air compressor supplier, in line with the concept of "self-confidence, integrity, heart and innovation", as always, we will wholeheartedly provide new and old users with better products and better services to create value for customers. The company's promise is the same quality, our price is cheaper; the same price, our quality is better!

As a special type of air compressor, oil-free air compressor is widely used in laboratories, hospitals and other industries with high requirements for compressed air quality. For repair and maintenance, the oil-free air compressor also has some different requirements from other air compressors. Granklin air compressor summarizes the following suggestions for your reference: without the guidance of technical personnel, do not disassemble the air compressor, replace the air compressor accessories or change the parameters without permission, so as not to bring bad consequences. When the air compressor is not suitable for work, it is necessary to form a good habit of cutting off the power supply, so as to avoid the damage of the air compressor caused by unstable voltage or power failure and bring hidden dangers.

our aim: customer first, reputation to win, good quality, high quality service. Our goal: Our constant goal is to work hard to provide customers with better cost-effective products. As an industry company, we will cooperate with you with international quality standards, fast and efficient service and reasonable prices, and create a better future with you!

Permanent magnet variable frequency air compressor energy-saving effect, the advantage of permanent magnet variable frequency air compressor is energy saving, generally energy saving 20% ~ 45%, the amount of energy saving depends on the working conditions of the air compressor and the setting of the parameters of the inverter. One of the major factors is the working conditions of the air compressor. When the customer's gas consumption fluctuates greatly, the better the energy-saving effect will be. The direct data is the proportion of no-load time to all working hours. It makes the air system more stable and reliable, reduces downtime and reduces production losses.

The screw air compressor motor also needs proper maintenance. It is worth noting that after the addition is completed, the temperature of the bearing is better than 120 ℃. The site was subsequently restored. The specific amount to be added depends on the temperature of the motor bearing after filling. If the temperature of the motor bearing is still lower than 70 degrees after adding grease, it can be added. This is basically the maintenance of the motor of the screw air compressor. granklin air compressor warmly reminds us that after the motor of the screw air compressor fails, the first thing to find out is the source of the failure, whether it is caused by improper protection of the system or overload operation, etc.

    How to see whether the screw air compressor is frequency conversion type

    The simplest point is to see whether it contains a frequency converter, and the second is to see whether the motor changes its speed according to the actual working conditions during operation. There are many factors to look. Speed directly affects the oil pressure and high and low pressure. I can see whether there is frequency conversion in current or not. Literally understood, the speed of the variable frequency air compressor is almost the same as the fixed frequency under the working state. When the air compressor is not in the pumping state, the motor frequency will automatically drop and the input power will be reduced to achieve the effect of energy saving.
