First, I HDSR series clover Roots blower. Flow exceeds 80m3 / min at the fan bearings are installed thermocouple can always monitor the tank temperature, prevent overheating produce blasting machine phenomenon. Second, the negative pressure blower, special gas blower (piston ring seal, 0 leakage) and our production level of the world's leading wind turbine mechanical twin tank design to avoid frequent contamination of butter. III. High blower assembly requirements, the error is 5-10 wire. All the fan assembly by the company's own production plus a fourth, fans purchased parts used in all well-known international or domestic manufacturers of accessories. Such as: NSK bearings imported from Japan or Sweden, SKF Bearings; (based on sample sizes less than 300 fans are NSK) and also greater than the general domestic manufacturers to adopt little bearing type. Japan's imports of seal TTO oil seal; good sealing effect, wear-resistant and durable. The United States imports Gaici Pi belt belt; good heat dissipation, and more durable. Gears domestic Zhuzhou Gear; gears 20CrMnTi (20 Cr, Mn, Ti) tooth grinding, precision five fifth, our drive shaft is 40Cr (40 Cr) material. Impeller and shaft are the overall thermal loading, can effectively avoid the fan is running out of sync between the impeller and the drive shaft, to ensure the stability of the fan running. (Now the impeller and shaft mounting technology is the most advanced thermal loading technology. Fission technology has gradually been eliminated, its stability and durability are weak) Sixth, I produced the Roots blower uses in and out of the outlet the spiral shape of the technology, to ensure the fan does not affect performance on the basis of effectively reducing fan noise. Seventh, in particular for the delivery of gas, I study the way the use of a piston ring seal, which can effectively control the special gas leak, the full realization 0 leak. Eighth, the company has more quality, production management system, to achieve a mutual exchange of parts, low production cost, short-term delivery targets. Under normal circumstances the fans, have adequate inventory can be achieved immediately available. ?? Contact:? 15,628,816,302 Manager Zhou QQ:???? 2850867350 ?????????
