Precautions for the maintenance of Roots blowers
Release date:
2021-02-01
The Roots blower is a positive-displacement fan. Its key components include the impeller end faces and the front and rear end covers of the fan. The principle behind its operation is that two rotor blades, rotating in opposite directions within the cylinder, compress and convey gas. This type of blower features a simple structure and is easy to manufacture. It is widely used in applications such as oxygen enrichment in aquaculture, aeration in wastewater treatment, and cement conveying. It is particularly well-suited for gas transportation and pressurization systems operating at low pressures, and can also be used as a vacuum pump. Below, we’ll introduce some important maintenance considerations for Roots blowers.
Roots blower This is a positive-displacement fan, featuring impeller end faces and front and rear end covers of the fan. Its operating principle is based on a rotary compressor that uses two rotor blades with specific profiles to perform relative motion within a cylinder, thereby compressing and conveying gas. This type of blower boasts a simple structure and easy manufacturing process, making it widely used in applications such as oxygen enrichment in aquaculture, aeration in wastewater treatment, and cement transportation. It is particularly well-suited for gas delivery and pressurization systems in low-pressure environments and can also be employed as a vacuum pump, among other uses. Next, we’ll discuss the key maintenance considerations for Roots blowers.
1. The maintenance and servicing of Roots blowers should be based on specific operating conditions, with a reasonable maintenance system established, carried out on schedule, and properly documented. It is recommended to perform a major overhaul annually and replace bearings and other vulnerable components.
2. Before disassembling the machine, measure the mating dimensions of the Roots blower, make a record, and label the parts to ensure that the original mating requirements are maintained after reassembly.
3. Regularly check the tightness of all components of the Roots blower, as well as whether the locating pins are loose. Also, inspect the inside of the machine for oil leaks and ensure there is no scaling, rusting, or flaking.
4. Pay attention to whether lubrication and heat dissipation are functioning properly, monitor the quality of the lubricating oil, and constantly listen for unusual noises during the operation of the blower. Also, ensure that the equipment is not operating under unqualified conditions, and pay close attention to the regular grease lubrication.
5. Sometimes it doesn't appear immediately. Roots blower Overload may occur; therefore, pay attention to the trends in intake pressure, exhaust pressure, bearing temperature, and motor current to determine whether the machine is operating normally.
6. After major overhaul, the oil tank of the new machine or the Roots blower should be cleaned and operated according to the prescribed procedures. It is recommended to replace all lubricating oils after 8 hours of operation.
The safe operation and service life of Roots blowers are significantly influenced by various human factors. Proper maintenance and care can effectively extend their service life and reduce the failure rate.
The above is Roots blower Introduction to maintenance items.
