In the industrial field, screw compressors, as the core air source equipment, are widely used in machinery manufacturing, chemical industry, food processing and many other industries. However, there are many different types of screw compressors on the market, and there are significant differences in the performance of different products, which often confuses enterprises in the selection of ZAKF
Screw Air Compressor suppliers, as a professional manufacturer of fluid machinery industry for many years, will provide you with an in-depth analysis of the performance differences between different screw compressors, and provide a scientific selection guide, to help enterprises choose the right equipment to improve production efficiency.
Analysis of the performance differences between different screw compressors
Compression efficiency and energy consumption
Compression efficiency is a key indicator of the performance of screw compressors. Oil-injected
Screw Compressor through the injection of lubricating oil to achieve sealing, cooling and lubrication, can effectively reduce the heat and friction in the compression process, compression efficiency is high, and stable operation, suitable for gas supply continuity and stability of high demand occasions, but its energy consumption is relatively high. The oil free screw compressor does not use lubricating oil, to avoid the problem of oil pollution, compressed air purity, but due to the lack of lubricating oil assistance, its compression process heat and friction is larger, compression efficiency is slightly lower than the oil injected screw compressor, energy consumption is also relatively high.
ZAKF screw air compressor supplier produces
oil-injected screw compressors, the use of advanced asymmetric rotor technology, compared with the traditional models, compression efficiency increased by 15 percent. ZAKF's oil-injected screw compressors use advanced asymmetric tooth rotor technology to increase compression efficiency by 15%-20% compared to traditional models, and are equipped with energy efficient motors to ensure efficient air supply while reducing energy consumption;
oil-less screw compressors use an innovative cooling system and optimized rotor design to increase compression efficiency and reduce energy consumption as much as possible.
Discharge Pressure and Flow Rate Ranges
The discharge pressure and flow rate ranges of different screw compressors vary. Generally speaking, small screw compressors with low discharge pressures and low flow rates are suitable for laboratories, small processing workshops and other scenarios with low air demand. Medium and large screw compressors with high discharge pressures and high flow rates are able to meet the high compressed air demand and pressure requirements of large factories, mines and other production environments. For example, ZAKF has launched a variety of specifications of screw compressor products for different industry needs. Its low pressure screw compressor discharge pressure is usually 0.4-0.7MPa, suitable for textile, electronics and other industries that do not require high pressure but need a stable air supply; medium and high pressure screw compressor discharge pressure up to 1.0-3.0MPa, widely used in chemical industry, machinery manufacturing and other fields, to meet the needs of high-pressure air tools, high-pressure blowing and other air needs.
Noise and Vibration Level
Noise and vibration during operation not only affect the working environment, but also reflect the performance and quality of the equipment. Screw compressor noise and vibration mainly comes from the operation of the rotor, motor operation and airflow pulsation. Due to the poor design and manufacturing process, some screw compressors have high noise and vibration during operation, which may affect the health of the operators and disturb the normal operation of the surrounding precision equipment.ZAKF screw air compressor suppliers pay attention to the detailed design of the products, and optimize the dynamic balance of the rotor, adopt the acoustic enclosure and vibration damping device, etc, to reduce the noise and vibration of the equipment during operation. For example, ZAKF's silent screw compressors can be operated at less than 65 decibels, which will not cause significant interference even when used in crowded workplaces.
Maintenance costs and service life
The maintenance costs and service life of screw compressors are closely related to the quality of the components, the design and the routine maintenance. Some low-priced screw compressors use low-quality parts, although the initial purchase cost is low, but in long-term operation, the parts wear and tear fast, high failure rate, frequent maintenance, high maintenance costs and short service life. zakf screw air compressor suppliers use high-quality raw materials and advanced manufacturing process to ensure the reliability and durability of the equipment's core components. For example, the screw rotor is made of special alloy material, which is precisely processed and heat-treated to ensure strong wear resistance and a long service life of more than 100,000 hours. Meanwhile, the equipment is designed to be easy to maintain, and the key components are easy to be replaced, which effectively reduces the maintenance cost and downtime of the enterprise.
The key points of scientific selection
Clarify the actual demand for air
Enterprises in the selection of screw compressors, first of all, we must accurately assess their own actual demand for air, including the required discharge pressure, flow rate, air continuity, etc. For example, for the spraying industry, which requires pure compressed air and high pressure stability, oil-free screw compressors can be prioritized. For example, for the spraying industry, the need for pure compressed air, and high pressure stability requirements, can give priority to the oil-free screw compressor; for the mining industry, due to the need for high-pressure, high-flow compressed air to drive rock drills and other equipment, you should choose a high-pressure, high-flow screw compressor. zakf screw air compressor suppliers to provide professional consulting services for the selection of technical team will be in-depth production of the enterprise site, to understand the air-using links and needs. Our technical team will go into the production site of the enterprise to understand the air consumption and demand, and recommend the most suitable model for the enterprise.
Consider the cost-effectiveness of the equipment
In addition to the performance parameters of the equipment, the enterprise should also consider the cost-effectiveness of the screw compressor, including the purchase cost, energy cost, maintenance cost and service life of the equipment, etc. Although the price of high-performance screw compressor is relatively high, it is not easy to find the most suitable model. Although the price of high-performance screw compressors is relatively high, in the long run, its energy-saving effect and low maintenance cost can save a lot of money for enterprises. zakf screw air compressors ensure high performance, and at the same time, through the optimization of the production process and supply chain management, to reduce the cost of the product, to provide cost-effective equipment for the enterprise to choose. For example, ZAKF's permanent magnet inverter screw compressor can save up to 30%-40% energy compared to traditional fixed frequency compressors. Although the initial investment is a little higher, after 1-2 years of use, the savings in electricity cost can cover the difference in equipment price.
Emphasis on after-sales service protection
Good after-sales service is an important guarantee for the stable operation of the screw compressor. Enterprises should choose a supplier with a perfect after-sales service system, including timely repair, regular maintenance, supply of spare parts, etc. ZAKF screw air compressor supplier has a professional after-sales service team, with service outlets in many places around the world, promising to respond to customer needs within 24 hours, within 48 hours to arrive at the scene of the maintenance, to provide a full range of after-sales support for the enterprise, so that enterprises to use the equipment without worries. We provide all-round after-sales support for enterprises, so that they can use the equipment without any worries.
