Roots fan in the process of selecting those issues that must cause everyone to pay attention to it? On this issue, Roots fan small make up to take you to understand. 1, the transportation medium Roots fan can not directly transport more particles, impurities more media, such as high concentrations of oil and gas media, usually used to transport clean air. Secondly, the strong erosion of toxic gases can not be transported, mainly due to the sealing of the Roots fan, although the Roots fan at a certain level may wish to do 0 leakage, but time can not guarantee 0 leakage, once the leakage occurs, the toxic gases, flammable and explosive gas collars will be quite dangerous, so, can not be transported with the Roots fan, but also need to look at the transport...

Roots fan is not emptied before use, then such an operation will bring those hazards to the Roots fan? On this issue Roots fan editorial take you to understand. ① motor! Motor voltage is unchanged, the speed is unchanged, the demand force is greater, do more work. Motor power increases, the current increases the current is too large, the protection system stop. No protection system motor burned out! ②Fan! Fan by the heat generated by the compressed gas, the heat can not be discharged in time! Fan heat, soften, brittle fan casing! Fan at the same time by two external forces 1, the motor on the fan spindle, bearings of the strong torsion. 2, the inner chamber of the air pressure on the fan casing of the outward push. Combined with heat and force, the fan cracked, or even exploded...

Roots blower in the use of the process of oil leakage, so what is the cause of it? How should it be solved? Roots blower editorial take you to understand.

Roots fan in the process of work out of the gas is hot, so what is the reason for this situation? Roots fan editorial take you to understand. 1、Forced gas transportation Roots blower in the delivery of gas, the need for forced compression of the fan, fan selection, there is a pressure parameter, such as 39Kpa, Roots blower in the compressed air, the maximum pressure can withstand 39Kpa, the pressure of the pipeline in front of the party reached 39Kpa, the fan can overcome the pressure of normal operation. Forced compressed air operation, will inevitably generate heat, so the Roots blower exhaust fan out is with a certain temperature. 2, the inlet temperature Conveying clean...

Roots fan in the use of the process of noise, so what is the solution to the noise of the Roots fan? Roots fan editorial take you to understand. 1, import and export silencer transformation Roots fan import and export silencer must be retrofitted, and to use good quality silencer, silencer pipe wall should be thicker, so as to ensure the noise reduction effect of the silencer. 2、Soundproof room Generally speaking, if you want to significantly reduce noise, it is the use of soundproof room, the fan is placed in a small room alone, so as to achieve the best results, the soundproof room can be customized individually, according to our experience, the effect of the soundproof room is very good. For...

Roots fan in the process of purchasing the first need to understand its type, so that you can choose a more suitable for their own Roots fan, about the type of Roots fan I take you to understand. 1, Roots fan in accordance with the different ways of working can be roughly divided into single-stage and double-stage points, of which there is only a compression stage of the blower, we call it a single-stage fan, and will be two single-stage fan in series, two consecutive compression of the gas fan we call it a double-stage fan. 2, according to the number of impeller head: two-leaf Roots fan and three-leaf Roots fan; 3, according to the use of points: kiln fan, gasification fan, aeration fan; 4、According to the type of medium: air...

Roots blower in the use of the process of oil change is unavoidable, then Roots blower in the process of changing the oil in those details need to be understood? Roots blower editorial take you to understand. 1, Roots blower lubricant volume assessment Roots blower oil amount of each model can always check the gear side of the oil mirror, in the shutdown to keep the oil level in the center line between. If the oil level is lower than the center position, you need to add lubricant in time, if the oil level is higher than the center position, oil leakage will occur. 2、Roots blower gear oil change order Clean out the gear oil first, inject new gear oil, start running for 300 hours, and then change the gear oil once every 1000 hours. 3、Roots blower...

Roots fan can not be separated from the fan in the process of use, so how much do you know about Roots fan related knowledge points? Roots fan small editor to take you to understand. 1, install frequency converter Installation of frequency converter, can adjust the motor speed, speed is an important factor affecting the fan air volume, frequency converter can adjust the motor speed, motor speed adjustment, fan air volume can be adjusted, generally in the case of fan without other failure problems, adjust the fan speed can change the air volume. 2, fan failure caused by the reduction of air volume, how to do?
