The size selection of the screw air compressor depends on two parameters. The first is the working pressure of the product air; the second is the air volume required per minute for the product air. Knowing these two parameters, you can basically determine the model of the screw compressor.
In the
Oil Free Rotary Screw Air Compressors Factory, in addition to considering the gas consumption and pressure, the size should also be selected according to the use occasion and the design and planning diagram of the machine room site, so as to avoid the small site, large equipment that cannot be placed or barely put down, but subsequent maintenance is inconvenient The problem.
1. Gas planning
1. Properly select the capacity of the air compressor, if it is too large, it will easily cause no-load waste.
2. The number of filters should also be selected according to the gas consumption requirements of the enterprise. Excessive pressure loss will also increase and waste will be high.
2. Power frequency and frequency conversion selection
Although the frequency conversion screw machine has good performance and power saving, it is not absolute. When the customer's gas consumption is more stable throughout the day, the power consumption of the power frequency screw machine and the frequency conversion screw machine is not much different. Frequency conversion machines are much more expensive than industrial frequency machines. In this case, you can choose a power frequency motor to reduce the purchase cost.
3. System control and management
1. Regularly maintain the unit to avoid late maintenance or no maintenance. Because unscheduled maintenance will lead to an increase in equipment failure rate, thereby shortening the service life of the unit.
2. Pay attention to the maintenance and replacement of pipeline precision filters. The filter is easily damaged and clogged after long-term use, resulting in large pressure loss and large waste.
3. Regular maintenance to prolong the service life of the unit.
4. Keep the machine room clean and ventilated, and check all parts of the air compressor regularly to avoid air leakage.
PRODUCT FEATURES
UItra-low frequency speed control technology far surpasses standard VSD compressor systems.Capable of lower than 15Hz operation，this system is truly capable of constant variable pressure operation and significant energy saving.
USoft-start feature allows for little or no impact on the power supply system and marginalises mechanical wear and tear up on start-up.
Leakage is always present in any air system.At full pressure a good system can loose 0.2Mpa.Zerlion VSD machines can reduce that loss by up to 25%simply by supplying the air pressure that is required.
