Why choose Zero Air Consumption Drainer?
During the working process of the compressed air system, condensed water will be precipitated, and the condensed water contains oil and particulate impurities. If the condensed water cannot be discharged in time, it will seriously affect the quality of the gas. There are many ways to discharge condensed water, such as installing a manual ball valve, an electric ball valve, an electronic drain valve, etc. However, the amount of condensed water discharged is not constant, but fluctuates with various factors such as temperature, humidity, and compressor full load rate.
If you choose a manual ball valve, an electric ball valve, and an electronic drain valve, a certain degree of compressed air loss will occur, so we recommend that you choose a zero-gas drainer produced by Nanjing Daoshida to avoid unnecessary compressed air loss.
How much money can you save by choosing a [zero-gas drainer]?
The following figure shows the cost structure of a compressed air system for ten years:
As a secondary energy source, compressed air is a very expensive power source. Take a 75KW air compressor, which is used 300 days a year as an example. The electricity cost alone can be as high as 75kwx 7200hr = 540000kw.h. In addition, there are other costs such as valuable machine depreciation, maintenance and repair, and purchase and maintenance of post-processing equipment. The unit cost of compressed air per cubic meter exceeds 0.12 yuan.
Example 1: Current air storage cylinder drainage status: 1/2” ball valve is always in a slightly open state for drainage. Calculated with a 3mm exhaust aperture, when the system pressure is 7bar, the amount of air leaked from the manual drain valve is 0.64m3/min. Estimated to be used 300 days a year, the total cost of compressed air lost each year is:
0.64m3/min × 60min/hr × 7200hr × 0.12 yuan/m3 = 33178 yuan/year
Example 2: The current refrigerated dryer is equipped with an electronic timed automatic drainer, the drainage state is 5 seconds every 2 minutes, the drainage aperture is 6mm, when the system pressure is 7bar, the leakage at the drainer is 2.56m3/min, then the annual air leakage is: 2.56m3/min x 2.5min/hr x 7200hr/year = 46080m3/year, according to the average effective drainage rate of 40%, the annual emptying loss is: 46080m 3/year×(1-40%)×0.12 yuan/m3=3318 yuan/year
Long-term use of gas-consuming drainers not only causes energy waste, but also leads to a series of problems such as increased energy costs, fluctuations in system pressure, reduced air compressor life, and increased maintenance costs. It is completely necessary to choose a zero-gas-consumption drainer.
What are the advantages of zero-gas-consumption drainers produced by Nanjing Daoshida compared with other manufacturers?
Special advantages of Niancheng Smart Drainers:
◆ Daoshida Niancheng Smart Drain adopts an innovative modular structure design to replace the traditional old structure. The old-fashioned adhesion structure requires complex internal terminal wiring, cannot be powered off during work, and the disassembly and assembly of sensors and discharge valves is very complicated. The modular structure of Smart Drain overcomes this series of disadvantages and is more convenient to use and maintain.
◆ The design of Dostar Niancheng Smart Drain has fast discharge speed, high action frequency and strong overload capacity.
◆ Dostar Niancheng Smart Drain is equipped with direct-acting solenoid valve, which has simple structure, stable performance and long service life.
◆ Dostar Niancheng Smart Drain has complete specifications and provides users with a wide range of choices in terms of drainage volume, working pressure, applicable voltage and product materials.
◆ Fault alarm function: When the drainer fails and the water level is too high, the sensor senses in real time, automatically enters the self-cleaning drainage mode, and can remotely output fault signals
◆ Dostar Niancheng Smart Drain can choose a translucent composite material shell to observe the changes in condensed water, which is very user-friendly.
◆ Dostar Niancheng Smart Drain has been finalized after six tests including pressure test, flow test, impurity test, electromagnetic interference test, water spray test and life test, ensuring long life and high reliability.
Unique advantages of Niancheng pneumatic drainer:
◆ Dostar Niancheng Mag-drain is a pneumatic zero-gas consumption drainer, which can effectively discharge according to the actual amount of condensed water produced, only draining water, not exhausting air, and avoiding compressed air loss.
◆ Dostar Niancheng Mag-drain adopts a specially designed float, which is pneumatically controlled according to the change of liquid level, and realizes automatic drainage through the pneumatic drain main valve without external air source.
◆ Dostar Niancheng Mag-drain drain valve has a large aperture (the aperture of the non-powered drainer on the market is generally about 1-2mm, which is easy to clog), and the drainage is smooth without fear of clogging.
◆ Dostar Niancheng Mag-drain adopts a translucent composite material shell, which can observe the changes of condensed water, which is very user-friendly.
◆ When used only for compressed air drainage, Mag-drain pneumatic drains can be used in flammable, explosive and other hazardous environments.
◆ Dosda Niancheng Mag-drain can provide special products for large water discharge, providing users with a wide range of choices.
◆ Dosda Niancheng Mag-drain series pneumatic drains are finalized after four major tests: pressure test, flow test, impurity test and life test, ensuring long life and high reliability.
