The importance of compressed air quality in the SMT industry

Compressed air is  the second largest power source after electricity , which  has been widely used in the SMT industry, such as: chip mounter of automatic multi-function, printing machine  of high precision solder paste , automatic wave soldering machine   pneumatic   equipment  etc. while many enterprises   take  configuration  of SMT production line , equipment selection, and subsequent installation and use  into consideration , which often only pay attention to the main equipment s election, ignoring the dryness and cleanliness  of compressed air as a air source , it leave a long-term risks   to the production assembly line .   The compressed air  is used  in the SMT assembly line is not only required to provide stable and sufficient  air pressure and flow, but also it  must be dry and clean. t he air contains impurities particle   such as water, oil, dust and so on. they enter the air compressor to compress  a fter a simple filter ing , these solid particles and compressed air

Technology Description of Biteman High Efficiency Precision Filter

In the Design norm for Compressed Air Stations-2002 , the filter is clearly defined: configuring filter of the appropriate accuracy in the before and after the air drying device when the user has quality requirements of compressed air , the compressed air should take effective measures to remove oil before entering the drying device when the compressed air needs to dry etc,. So high-precision filter is very vital in the compressed air purification system. Efficient precision filter is to remove oil mist, water, dust and rust and other impurities in compressed air. Working principle analysis of biteman high precision filter Filter cartridge adopts through&open design, which makes filtered impurities directly through the reservoir chamber, there is no need to penetrate via filter and discharge by automatic drainage valve; central filter using high-quality polymer filter material, it have a certain adsorption capacity to fully guarantee the filter effect for oil mist and other i

Hazard for the muffler breakdown of Absorption dryer

A silencer is a device that allows airflow pass through to reduce noise, reducing aerodynamic noise in the airflow path. According to the relevant provisions, it is necessary to take measures when the exhaust noise reach more than 75 dB. this noise will cause harsh working environment, damage to human health, reduce work efficiency. While it will reach up to 80 ~ 100 dB when the fast exhaust velocity arise strong exhaust noise of gas vibration due to a certain pressure of regeneration exhaust gas(when muffler breakdown, some impacts will occur above). Muffler is the terminal component of the adsorption dryer, and it is a delicate part because it has bad working conditions , leave a lot of dust and water vapor of the regeneration exhaust, and it is easy to produce muffler blockage when the temperature is appropriate there will be accumulation of condensate . It will bring great trouble to air dryer for normal operation once Muffler failure. the muffler go through the regeneration o

Advantage and disadvantage of Diffuser and Diffuser Plate for air Dryer

"Diffuser" and "diffuser plate" came into being to improve the adsorbent of gas direct impact and uneven distribution of gas and fluid during operation. Diffuse Orifice: just like "Shower head", to a certain extent, Diffusion orifice improve the phenomenon of uneven distribution of air flow , while closely orifice plate will increase the pressure drop of compressed air, and too thin orifice design, it’s very limited to uniform distribute air flow and eliminate dead ends, finally compressed air will form a "ditch short-circuit" phenomenon and the new "tunnel." Diffuser: just like "silencer", it play a role in dispersion buffer for air into absorption dryer, but can not solve the problem of uneven distribution of air flow. At the same time, it increase the resistance of compressed air to form pressure drop, then hinder regeneration via rapidly drain because of the existence of the diffuser (diffuser orifice).

Application of Pressure Dew Point in Compressed Air System

Air compressor make air’s volume reduced and pressure increased via doing mechanical movement, which is called compressed air. Compressed air is an important power source, it is widely used in many industrial fields, such as machinery, metallurgy, electronics, electric power, medicine, packaging, chemical industry, food, mining, textile and transportation etc. But the compressed air contains water, oil mist, impurities and solid particles, so it must be treatment trough filtered purification, after that resulting in dry, clean, oil-free compressed air. Filters can eliminate oil, dust , while air dryer can handle water. Dew point temperature (Td) It Refers to temperature of the water vapor saturated in the air at the beginning of the condensation, that is condensation temperature. At 100% relative humidity, the ambient temperature is equal to the dew point temperature. The smaller the dew point temperature much than , the smaller the dew point, which means the air much more dry. The d

Shenzhen Jinjia Group Co., Ltd. was founded in Oct 14th, 1996, which was listed on the SME board in China’s A-stock on Dec 5th ,2007(referred to as "JinJia stock",code: 002191), after that it become SME’s sample stocks in May 2008 . It is China's leading cigarette packaging company, and forward into the international famous brand packaging business. In early 2013, they decided to move production base to Jinjia Color Printing Industrial Park , Songgang, Baoan district, shenzhen, and upgraded the compressed air purification system to meet the business needs of the Group's rapid growth and strict requirement of Germany import’s fully automated printing assembly line for compressed air quality. Upgrading program of compressed air quality is that latest modular desiccant dryer from Shenzhen Biteman technology will replace traditional twin tower adsorption dryer, which will solve those problem, such as exhaust gas consumption, poor dehydration effect, instability
