Two Stages High Pressure Pneumatic Conveying Blower More Stable BKD -2000

About BKD
BK Roots Blower is a kind of product designed and manufactured according to the national standards and by the techniques introduced from American TUTHILL Co. This type blower is featured with simple structure and high cubage efficiency.
BKD series is a dual stage roots blower, which has two BKWblowers in series, can achieve higher pressure comparing with single one, also there is a middle cooling system between the first and the second stage, it ensures the standard temperature of the airflow to the second blower.

Working Principle

Roots blower is a cubage blower, and it discharges a fixed amount of air in proportion to its rotation speed. Every rotation, there is two lobes to finish three times absorbing and dischargeing air. Compared with two lobes blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.

Two paraller shafts have three lobes each, all the lobes keep small clearance with each other and housing inside. Every lobes rotatiomn, a certain air will be absorbed at inlet and transfeered form the housing inside surface to blower's diacharge port.

Two shafts will be turned by the timing gears, no any touching between lobes, so it can be turned at high speed without any lubrication inside. It has the following chaaracteristics: simply configuration; running smoothly;good performance stabilization. It has been widely applied in various industries.

Exihibition

B-Tohin Machine (Jiangsu) Co., Ltd. is a foreign invested enterprise established in 1994. It is located at Yixing Industrial Park for Environmental Science & Technology, one of State High-Technology Development Zones. With total registered capital of RMB 120 million and total investment of RMB 160 million B-Tohin is engaged in production and sales of HC blower, BK and YU Roots blowers,air compressor blower,screw blower, anti-corrosion and anti-explosion stainless steel Roots blowers, gear speed-up centrifugal blower, multi-stage centrifugal blowers and in the sales of other supporting products for water treatment in environmental protection, such as water pump (YU, WQ submersible pump, YYOW split case pump), mixer, dewatering machine, etc. By the purchase of a new building of 26000 m2 area in Yixing Economic Development Zone in 2015, the expansion of production scale is supported.

B-Tohin’s products have been widely used in various industries, including water treatment, construction material and cement manufacture, chemical industry, electricity, petroleum, steel, metallurgy, mine, food convey lines, etc., enjoying a good reputation among customers both in the overseas and domestic market.

In the company’s Research and Development Center, a technical innovation team composed of professor level Senior Engineers, Doctors, Masters and many undergraduates, is aiming at the service for environmental protection by tracing and developing the products of high level.

B-Tohin has made great investment in introducing CNC, full-automatic digital control lathes, CMM and other advanced equipment to ensure good quality. A complete set of advanced horizontal OKUMA CNC was introduced specially for the fine finish machining of blower cylinders and end-covers; a NC machine was imported for the processing of blower parts; a Taiwan Dahlih-made CNC was equipped for machining the parts of middle and large size blowers; and several back-forth curve machining planers were introduced for solving the problem of shapers’ precision problem. This kind of planer ranks among the advanced level in China which is specially designed for curve machining of blower rotors. In the beginning of 2015, we cooperated with Testing Laboratory of Shenyang Blower Research Institute (Quality Supervision & Inspection Center for Blowers of China Machinery Industry), and a whole set of blower performance test system was designed for us according to the Roots Blower Industry Standard by the Laboratory.

Passed the certification of ISO9001 & ISO 14001:2400, the company has been nominated as “High & New-tech Enterprises of Jiangsu Province” and “Pneumatic Technology Research Center of Jiangsu Province”. In successive seven years, B-Tohin has been honored as “Favorite Brand of Users in Water Treatment Industry” and “Main Enterprise in Chinese Roots Blower Industry” in 2014, it has been awarded the title of “2014 Top 10 Brands in Chinese Water Industry” on website.

Being a member of National Commission for Pneumatic Conveying and National Technical Committee of Standardization of Blower, and one of the sponsors of National Union of Environmental Protection Equipment Brands, B-Tohin Machine has been an excellent and famous enterprise in environmental protection blower industry.

B-Tohin’s tenet of “Eternal pursuit of improving, eternal promise of satisfying customers” and spirit of “Together with Heat” are always kept in every employee’s mind and in every step of company management. All the honors belong to the past only, people of B-Tohin will make every endeavor to design and manufacture more perfect products for contributing more to the related industries both at home and abroad and to our domestic machinery industry.
