Chengdu Roots Blower Factory: Causes and Solutions of Roots Blower Vibration

　　Chengdu Roots Blower FactoryIntroducing the Causes and Solutions of Roots Blower Vibration

Roots blower in use, due to various reasons, vibration increased, after the destruction, more serious when it will cause serious equipment accidents. The following are some fault phenomena of Roots blower vibration.

(1) Design scheme: Roots blower design is generally customized according to the use scene, ambient temperature, exhaust air volume, air pressure, material and other aspects of the fan, but some enterprises have not completely selected according to various factors, resulting in unreasonable fan design scheme, poor dynamic performance, unscientific vibration structure in operation, and incorrect calculation of thermal deformation in the area where the stress design operation speed ratio is close to or falls into the critical speed, poor thermal condition.

(2) Installation and maintenance: Roots blower installation precision plays a very important role in the operation of the fan. If the assembly precision can not meet the installation specifications, it will damage the operation of Roots blower. In the fan setting process, the setting of mechanical equipment is unreasonable, the parts are displaced, the shaft system with larger preload is unreasonable for the long-term placement of the motor rotor with poor mechanical equipment assembly clearance, excess capacity and incorrect adjustment of positional relationship, the dynamic balance accuracy changes, and the safety inspection is not carried out as required, thus destroying the original matching nature and precision of mechanical equipment.
 

(3) the actual operation of the reason: in the use of roots blower, the centrifugal fan maintenance, maintenance is good or bad, the running quality of roots blower plays a key role. For example, the deviation of the allowable value of the process index and the abnormal operating condition of the equipment; The equipment operates under over-speed ratio and overload, which affects the working characteristics of the equipment. Runnerization or poor refrigeration; Partial damage and fouling of the motor rotor; Operation error in the whole process of starting and shutting down or adjusting speed, uneven thermal deformation or long stay in the critical area.

(4) equipment deterioration reasons: general machinery and equipment in the use of the process has a certain period of time, to reach a certain period of time equipment will be malignant change. The same is true for Roots blower. During long-term operation, the deflection value of the motor rotor will increase or the dynamic balance will deteriorate, the motor rotor will partially destroy, fall off or crack, parts will be damaged, crevice corrosion or rust, etc., and the bearing force of the mutual matching surface will deteriorate, resulting in clearance matching, too loose, etc., destroying the precision of mutual matching performance, uneven settlement of the foundation of the sound card frame, and shell deformation.

chengdu roots blower factory:Application of Roots Blower in Wastewater Treatment

Chengdu Roots Blower Factory: The municipal sewage project is what we usually talk about in a wide range of sewage treatment stations. The main purpose of Roots Blower is to produce oxygen from explosive gas. The main purpose is to give the hydrolytic acidification tank to reflect the oxygen production and fluidity of bacteria, to ensure the stable survival of bacteria, so as to remove harmful and easily reflected chemicals from domestic sewage according to bacteria, and to provide a good environment for the next step of deposition and other solutions.

This kind of Roots blower generally supplies dozens or even hundreds of pools according to the supervisor, so it generally requires more flow and long service time, which gives very strict application regulations for the operation of Roots blower itself.
