About the method of adjusting the sound of Roots blower

I 'd like to explain to you the method of adjusting the sound of Roots blower and the solution of current overload. The correct method of adjusting the air volume of Roots blower: 1. Adjust the speed of the motor. As we all know, the higher the blower speed, the greater the air volume, and the more air compressed by the Roots blower per unit time, the greater the air volume.

What are the factors affecting the price of roots blower?

Generally, users who buy Roots blowers will ask about the price of Roots blowers: how much is a Roots blower, or how much is a kilowatt Roots blower. Faced with such a question, it is really difficult to answer directly. Because the price of Roots blower is affected by many factors, we need to understand these factors that affect the price of Roots blower in order to get an accurate blower quotation. 1, The influence of fan parameters on the price of Roots blower Let's put aside other factors and only target the same type of Roots blower. Because the parameters of the blower are different, the price of the Roots blower is often different, such as the pressure value, flow value, motor specification, motor model, motor power, etc. of the Roots blower. Will affect the price of the fan.

Do you know the adjustment method of noise and clearance of Roots blower?

Do you know some methods of adjusting the noise and clearance of Roots blower Methods of noise resolution and clearance adjustment when using Roots blowers Roots blower motor overload reasons: 1. The pressure difference is larger than the specified pressure, that is, the back pressure or the inlet pressure is large; 2. Compared with the flow required by the equipment, the pressure becomes larger due to the excessive flow of the fan; 3. Inlet filter blockage, outlet pipeline failure or blockage;

Roots vacuum pump how refrigeration?

How to cool roots vacuum pump? 1. Internal cooling of the rotor: In order to make the Roots vacuum pump work under a higher pressure difference, a cooling method can be adopted, that is, the rotor is cooled by circulating oil, and the oil holes and oil passages are driven into the shaft at both ends of the pump shaft. Head, and then discharged from the other end through the inner wall of the rotor. In addition to cooling the rotor, the cooling oil also lubricates the gears and bearings. This cooling effect is very good. When the pump is running, the rotor temperature is lower than the casing temperature. This method is usually used for large pumps. For example, when working under a pressure difference of 80 Torr, the rotor temperature of the Roots vacuum pump is 78 degrees lower than that of the housing. Simultaneously

The difference between roots blower and centrifugal fan

The difference between roots blower and centrifugal fan Roots fan is a positive displacement fan. The delivered air volume is proportional to the number of revolutions. A small gap is always maintained between the end face of the impeller and the front and rear end covers of the fan and between the fan impeller. Driven by the synchronous gear, the downwind is transported from the air inlet of the fan along the inner wall of the shell to the discharge side. Centrifugal fan is to rely on the input of mechanical energy, improve the gas pressure side by side to send gas machinery, it is a kind of driven fluid machinery. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings ventilation, dust and cooling; boilers and industrial furnaces ventilation and

The principle of Roots vacuum pump air cooling

Roots vacuum pump for air cooling. Roots vacuum pumps generate heat by conveying and compressing gas, which needs to be transferred from the rotor to the housing. However, at low pressure, the heat conduction and convection performance of the gas is very poor, so the heat absorbed by the rotor is not easy to dissipate, resulting in the rotor temperature is always higher than the shell temperature Due to the thermal expansion of the rotor, the gap between the rotor and the rotor and between the rotor and the pump casing is reduced, especially when the pressure difference is also high, which can even cause the rotor to seize and damage the pump. In order to make the Roots pump work under high differential pressure, expand the scope of use, and improve the reliability of the pump, we need to try to dissipate the heat generated by the rotor.

Selection Skills of Roots Blower

At present, most of the roots blowers on the market are three leaf type. The three-leaf Roots blower adopts two sets of three-leaf impellers, and each revolution completes 3 suction and exhaust. Belongs to the volumetric fan, is a constant volume rotation of the pneumatic machine. Simple structure and stable performance. Selection Skills of Roots Blower 1, the choice When selecting Roots blowers for sewage treatment plants, product samples from Roots blower manufacturers show performance parameters under standard intake conditions. However, the Roots blower is not in a standard state in actual use. When the environmental conditions of Roots blower such as temperature,

Requirements for the use of Roots blower

Roots blower is a positive displacement blower. At present, most of the roots blowers on the market are three leaf type. Each rotation of the three-leaf Roots blower is completed by two groups of three-leaf impellers for three times of suction and exhaust. The cylinder is contained by a shell and walls at both ends. A pair of impellers "block" (because there is a gap, the two impellers are not in direct contact) separates the air inlet from the air outlet, and a pair of impellers are synchronized. With the rotation of the gear, the two impellers rotate at a constant speed in the cylinder. During the rotation process, the gas at the air inlet is continuously pushed to the exhaust port by the impeller, so as to achieve the purpose of forced exhaust. Simple structure and stable performance. The input gas consists of two

How to debug roots blower?

Because the Roots blower is a high-speed running machine, it will cause vibration. The pulse of the internal air will make the vibration of the Roots blower larger, so it should be fixed on the ground when installing the Roots blower. According to the blower model, dig a 150*150mm square 300mm deep square pit from this position, dig out the bottom bolts, connect the fan with bolts and nuts, and finally fill the square pit with cement concrete. If the concrete is fixed, then Tighten the nut.
