Detailed Product Description: | Hangzhou Xingda ventilation equipment to undertake all types of tin ventilation engineering, ventilation engineering tin Hangzhou, Shaoxing tin ventilation engineering, fume purification project in Hangzhou, Hangzhou, engineering, installation and design of ventilation, fire smoke hotel kitchen project, Hangzhou, central air-conditioning duct installation and other train service. The company has experienced professional and technical personnel, Jiande metal duct, which specializes in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection design and installation . Reduce ventilation noise source in noise control requirements of the occasion should be used in low-noise ventilation equipment. Different types of ventilation equipment, with the consent of wind, air pressure, centrifugal ventilation equipment airfoil blade noise, ventilation equipment centrifugal type blade forward version noisy. Appropriate to reduce the speed of ventilation equipment. Circumferential speed of the impeller rotation noise ventilation proportional to the square of 10, the circumferential velocity vortex noise impeller 6 th (or 5 th) proportional. Therefore, to reduce speed to reduce noise. Design of ventilation systems, should try to reduce the pressure loss of the system. When the total amount of losses and pressure ventilation system is large, it can be divided into small systems. Flow velocity in the pipe should not be too high, so as not to cause noise regeneration. Airflow velocity should be selected according to the different requirements of the relevant provisions within the established pipeline. Hangzhou Xingda ventilation equipment to undertake all types of tin ventilation engineering, Hangzhou tin ventilation engineering, metal duct price Hangzhou, Shaoxing and tin ventilation engineering, fume purification project in Hangzhou, Hangzhou ventilation engineering, installation and design, kitchen hotel fire smoke engineering, production metal duct, Hangzhou, central air-conditioning duct installation and other train services. The company has experienced professional and technical personnel, specialized in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. V-iron Category: Inspection V-iron, crossed V-iron, multi-port V-iron, single-port V-iron V-type iron purposes: for shaft inspection, calibration, marking, can be used to test the workpiece vertical the degree of parallelism. Detection precision shaft parts, dash, instrument and fixed clamping machining. v-shaped iron manufacturing standards: According to the National GB4972-85 standards for manufacturing cast iron V-frame press JB / T8047-95 standards for manufacturing, using HT200 material supply in pairs. V-iron material classification: cast iron V-shaped iron material can be divided into load requirements ductile iron and gray iron V-frame types: V-type frame carrying means V-shaped frame to withstand the weight per unit area after, V-shaped frame of the deflection. For ease of understanding, we can be seen V-shaped frame put away the workpiece, without affecting the normal use of the situation, V-shaped frame to withstand the pressure.
