The troubleshooting method of LC Roots pump is the same as the cause of noise

Firstly, troubleshooting methods for Roots oil pumps: Whether it is a Roots oil pump or any other equipment, it is impossible for them to never fail. However, through some maintenance and repair methods, it is possible to reduce or even avoid equipment failure problems. At the same time, in case of equipment failure, timely handling is also necessary to reduce the adverse effects caused by the failure. So let's talk about how to deal with and respond to some malfunctions in the Roots oil pump

1. The Roots oil pump is overloaded

The power required for compressing gas in the Roots oil pump is directly proportional to the pressure difference. Once the gas pressure difference is too high, the Roots oil pump may experience overload, causing damage to the motor winding. To prevent the impact of Roots oil pump overload, three methods can be used: mechanical automatic pressure regulating bypass valve, hydraulic coupling, and vacuum electrical component control of pump inlet pressure

2. Wear of bearing position

During operation, Roots oil pumps are often affected by harsh environments such as high temperature, high pressure, strong corrosion, and cavitation erosion, resulting in wear, corrosion, leakage, and other phenomena. The wear of the transmission parts is a common problem in Roots oil pumps, with a large quantity and frequent damage. The contemporary new method is to use polymer composite materials, which have strong adhesion, excellent compressive strength, and comprehensive properties such as workability

So when the Roots oil pump encounters the above types of faults, timely maintenance and treatment should be carried out in the correct way to minimize the impact of the fault problem. After dealing with the fault problem, relevant maintenance work should be done to improve the treatment effect and avoid the recurrence of the fault problem

Secondly, the reasons for the noise of Roots pumps

Whether it is Roots pumps or other equipment, it is rare that there is no sound during operation.

. So it is normal for everyone to hear some noise coming from inside the device when operating it, but if the noise is too loud, it indicates that there is an abnormality inside and needs to be repaired in a timely manner. So what is the reason for the noise on this device

1. Motor noise

Currently, the quality of motors varies. Motor noise often masks the noise of Roots pumps. Firstly, fan noise is generally high, and according to analysis, it should be caused by deformation of plastic fans.

; The second is the bearing noise caused by the use of poor quality bearings

2. Internal component noise of Roots pump

1) Collision of rotor

It includes collision noise between rotor and rotor, rotor and pump body, and rotor and side cover.

. The main reasons for this are: insufficient stiffness of the shaft, radial displacement of the rotor and gear positioning on the shaft, excessive or insufficient gear clearance, and excessive axial clearance of the bearings

2) The gear of Roots pump

The factors that affect gear noise are not only the machining accuracy of the gear itself, but also the parallelism of the two rotor shafts where the gear is installed.

3) Bearings

In addition to the accuracy of the bearings themselves, inadequate design may also cause an increase in bearing noise, such as excessive interference in the installation of the inner and outer rings of the bearings, insufficient shaft stiffness, insufficient supply of lubricating oil, and contamination by dust, water, corrosive gases, and liquids.

Therefore, the noise emitted during operation is mainly caused by collisions, wear, and other internal components, and these components that are prone to making noise are also relatively prone to wear and tear. Therefore, when repairing and maintaining equipment, these components need to be maintained
