Original title: What factors affect the selection of Roots blower, and what are the precautions for the selection of Roots blower
The selection of Roots blower is generally based on the air volume and pressure requirements used and the product parameter table of each manufacturer, and the model and power can be determined.
If these two parameters cannot be provided, the process requirements and uses, such as the size and quantity of the pool, can be provided. For example, for sewage treatment, the fan pressure can be determined according to the pool depth. A fan of 39.2KPA or more is required for a water depth of 4m. The air volume of the fan is calculated according to the cubic number of water.
When purchasing Roots blower, we need to face the problem of selecting the model of Roots blower, that is, determining the parameters of Roots blower. When the model parameters of the blower are selected, the fan manufacturer can conduct production and manufacturing. Therefore, our sales and technical customer service will encounter various questions about fan selection, such as: how to select Roots fan? The water depth of the sewage aeration tank is 6 meters. What is the appropriate model of Roots blower? How much is a Roots blower? And so on.
According to the different questions raised by customers, we can roughly know the customer's situation, which can be divided into four types. For example, professional customers are familiar with the parameters of Roots blower, and can easily and smoothly select the model, just report the parameters; There are also non professional customers who have a little understanding of the parameters of Roots blower, such as flow or pressure or one or several diameters, but do not know how to select the model. They need to further communicate with the technology to confirm the parameters of the blower, so that it can be easier to select the model; The third is the end user, who can tell the working condition information of Roots blower and some data required to the manufacturer, and the manufacturer can recommend the type selection; There are also Xiaobai customers. During general communication, they will first ask about the price of Roots blower, but cannot determine the selection parameters. At this time, the manufacturer needs patient guidance, prepare working condition information parameters and other data, and the manufacturer will help with the selection. Therefore, when meeting different customers, the sales technical customer service will choose different ways to solve the problem. In fact, even for highly professional personnel, it is recommended to select according to the manufacturer's guidance. Because there are certain differences in the fan models of different Roots blower manufacturers, it is recommended to follow the manufacturer's recommendations.
Roots blowers have different uses, different working conditions, different use scenarios, and hundreds of specifications and models. Therefore, in the face of so many uncertainties, it is necessary to know more about the factors that affect the selection of Roots blowers when selecting the appropriate and determined Roots blower model. Then, what factors affect the selection of Roots blower, and what precautions do you have for the selection of Roots blower. Follow Xiao Bian to understand.
Roots blower pressure refers to the pressure at the outlet of Roots blower. Roots blower itself does not produce pressure, but it refers to the ability of the blower to overcome the pressure of the pipeline, which depends on the air outlet pipeline and atmospheric pressure. Note that when selecting Roots blower, the blower within the pressure value must be selected. If the actual pressure exceeds the rated pressure value, the blower will be overpressure, which may lead to burning of the motor. If the pressure is insufficient, the required effect will not be achieved. The pressure unit of Roots blower is generally kgf/cm2 or kpa.
The flow of Roots blower is the volume of medium conveyed by Roots blower in a fixed unit time. When using Roots blower, it is generally necessary to use it to serve production or life to achieve a certain purpose or effect. The air volume is an important factor in the selection of Roots blower. The air volume is determined by demand, and some industries need more or less air volume. For example, if 200 cubic meters of sewage is aerated every hour, the value of 200 cubic meters of sewage is reflected in the flow of Roots blower, which needs to be converted into the appropriate fan flow. The unit of fan flow is generally m3/min or m3/h, but too large or too small the air volume will affect the aeration effect of the aeration tank.
The rotation speed of Roots blower determines the flow of the blower when the casing volume is the same. The higher the rotation speed, the greater the flow of the blower. The rotating speed also affects the service life of the fan. Because the rotor and casing of Roots blower will be slightly worn, the higher the rotating speed of Roots blower with the same parameters will be more worn than the lower, and the service life will be affected. Therefore, when selecting Roots blower, it is necessary to determine the rotation speed of Roots blower to meet the working condition requirements. The rotating speed unit of Roots blower is rpm/min. There are many factors that affect the selection of Roots blower, such as the condition of conveying medium, the use environment of blower, etc. With the change and increase of working conditions, more challenges and problems are encountered in the actual selection of Roots blower. Therefore, when selecting the actual model, it is more necessary to carefully consider the factors and precautions that affect the selection of Roots blower. By selecting the correct and appropriate model, the Roots blower can not only meet the demand, operate stably and well, but also save costs, achieve the effect of saving power resources, and save unnecessary capital waste and unnecessary maintenance costs, To achieve better goals and effects.
