This series of products are developed using advanced aerodynamic and acoustic technology. Through careful calculation of aerodynamics and acoustics and extensive testing, the total pressure efficiency of the fan reaches 89%. Higher static pressure to overcome the loss of pipeline resistance, and the use of special diversion runners and low-pressure large-flow impellers suitable for full ventilation. Compared with similar products, the new model consumes less power at the same flow rate. It has achieved the goal of comprehensive energy conservation. In terms of product structure, the product mainly consists of a cover plate and a simplified air inlet. Under the specified number of revolutions, it has the advantages of stable performance, good operation, low noise and vibration, reasonable structure, convenient disassembly and assembly, etc., and its louver damper automatically opens when it starts. 4-75x2E series ventilation and air conditioning double suction centrifugal fan is a fan for air conditioning ventilation unit. This series of fans is a low pressure and large flow back bend double suction centrifugal fan. It is made up of impeller with advanced gas dynamic and acoustic characteristics. The logarithmic spiral casing consists of Nos, 6.3, 7.1, 8, 10, 12, and 14 machine numbers. Compared with the same type of fan series, the 4-75 series fan has the characteristics of high parameters, good matching, compact structure, light weight, low noise, stable operation and convenient installation and maintenance. At the same machine number, the same speed, and the same power, there is a high wind pressure or air volume, and the wind pressure and air volume characteristics are hard, that is, when the system resistance changes greatly, the influence on the change of the fan is small, so it is widely used. General ventilation and air conditioning purification unit supporting. The application is mainly for indoor ventilation and ventilation of general factories and buildings. It can be used for blasting or exhausting, and can be used as a blower or return blower when it is matched with an air-conditioning purification unit. The type of gas to be transported is: air or other gases that are not self-igniting, non-corrosive to the machine, and harmless to the human body. No viscous substances are allowed in the gas. The dust content does not exceed 1501119/resistant, and the gas temperature does not exceed 80 °C. The product passed the title of the first-class product of Heilongjiang Province and the city's scientific and technological achievements award, and filled the gap in the province. The series of fire-fighting high-temperature exhaust fan products are approved by the Provincial Public Security Department Fire Bureau, developed after the project is established, and passed the Tianjin National Fixed Fire Extinguishing System and Fireproof Component Quality Supervision and Inspection Center. The fan is developed according to the design requirements of GBS Yiling 5:95 "Fire Code for High-Rise Civil Building Design". This type of fan is mainly used for fire prevention and exhaust of various high-rise buildings, and also used for underground construction projects and non-explosion-proof mines. Ventilation in the tunnel, in the case of ambient temperature does not exceed 280 ° C, in the case of the temperature of the transport medium does not exceed 10 ° C, can run continuously for 20 hours. The fan is an axial flow fan, and the fan main cylinder is connected to the fire exhaust passage of the high-rise building, and the driven motor has independent cooling passages, so that the fan can be prevented from being burnt due to excessive temperature rise of the motor during high-temperature exhaust operation. The motor will not affect the fan performance index when operating at room temperature. When the fan is used, the fans are not connected in parallel or in series. When it is unavoidable, the same type and same distance fan should be used. This machine is designed to provide disaster relief when there is a fire, and it can be used for ventilation.
Laser cleaning equipment is a new generation of surface cleaning high-tech products. It is very easy to install, manipulate and achieve automate. Easy operation, you only turn on the power and open the device, machine will be cleaned with no chemical reagents, no media, no dust and no water. With the advantage of manual adjustment of the focus, fit curved surface cleaning, good surface cleanliness and so on . Laser Cleaning Machine can clean the resin of subject surface, oil stains, stains, dirt, rust, coating, coating, paint.
Advantage of Laser cleaning
