How to choose the right aluminum shell motor for your machine?

First of all to understand what is the aluminum shell motor? 1. In general, we call MS series and ys series motors as aluminum shell motors, which are also popular three-phase asynchronous motors. How to choose the right aluminum shell motor for the machine? 1. Look at the seat number 2. Motor power is the number of HP and kW, commonly used in foreign countries and kW in China (1HP corresponds to 0.75KW, 2HP corresponds to 1.5KW, 3HP corresponds to 2.2kW, 4HP corresponds to 3KW) 3. Motor speed (2-stage motor speed 2800r / min, 4-stage motor speed 1400R / min is the most commonly used 6-stage motor 760r / min) 4. Shaft diameter of motor (d) 5. Motor installation mode: horizontal (B3), vertical (B5), vertical small flange (B14)  




How to choose annular high pressure fan

Release Time: 2020-08-08

With the progress and development of the times, annular high-pressure fan has become an important production machine. It is widely used in industry and agriculture, covering infrastructure, environmental protection industry, electroplating industry, aquaculture industry, industrial dust collection. However, how can we choose the quality and durable annular high-pressure fan in so many ring high-pressure fan brands? The following are some good purchasing methods! First of all, we need to know the principle of annular high-pressure fan, in order to better choose a better ring-shaped high-pressure fan. When the impeller rotates, due to the action of the separation force, the wind vane makes the gas move forward and outward, thus forming a series of spiral movements. The air between impeller blades rotates in a spiral manner and pushes the gas outside the pump body into the side groove (inhaled by the suction port). When it enters the side channel, the gas is compressed, and then returns to the impeller blade to accelerate the rotation again. When the air passes through the impeller and the side groove along a spiral track, the compression and acceleration degree of each impeller blade increases. With the rotation, the kinetic energy of the gas increases, which makes the gas pressure along the side channel further increase. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blade and silenced through the outlet. Brand selection: due to the wide use of high-pressure fan, and its selection is relatively complex; there are many fan brands in the domestic market, it is simple to understand the strength and scale of the supplier: registered capital, business scope, whether the company obtains the necessary certificate. Supplier's enterprise background, historical performance and growth: whether the company's actions are legal and standardized. Whether the product reliability, quality assurance and after-sales service are perfect: whether the product has passed CE certification, Rosh certification and SGS certification. Logistics is timely, payment methods and other options! Model selection: due to the wide use of high-pressure fan, its selection is relatively complex. Generally speaking, the following two steps need to be followed: 1. It is necessary to determine what function of the high-pressure fan is used on site, whether it is suction or blowing, and find out the pressure flow curve corresponding to the high-pressure fan; if the curve is misread, sometimes the selected products can not be used; 2; 2. According to the calculated pressure and flow, the working curve above the working point corresponding to the pressure and flow can be found on the curve chart; then the high pressure fan model is selected according to the working curve. The above is the IT Encyclopedia for you to summarize some of the principles and purchase direction of ring high pressure fan. There are many brands of annular high-pressure fans. I hope you can buy satisfactory products and you can buy the products you want carefully!
