Vulnerable brush faults can be specifically divided into three types: brush sparking, brush chatter, and uneven brush wear. The reasons for these three problems are as follows.The main causes of sparking of electric brushes are as follows: problems with the adjustment of the additional pole of the c

Whether diesel generator sets are used as backup power generation equipment or as the main power generation equipment in engineering buildings, strict adherence to rules and regulations is required from installation to use to avoid various faults and accidents caused by human factors. If there is an

1、 Sound insulation and noise reduction methods for generatorsIn order to effectively solve these noise problems, we have summarized the specific methods for generator sound insulation and noise reduction as follows:1. Install sound insulation walls between the generator and the roomThe use of this

1、 PurposeStandardize the operation and management of diesel generators to ensure their good operation.2、 Applicable scopeApplicable to the operation and management of diesel generators within the property jurisdiction.3、 Responsibilities1. The supervisor of the engineering department is responsi

Due to the use of pressure seals in multiple parts of the diesel generator engine, such as between the cylinder liner, piston, and piston ring, and between the turbocharger and the turbocharger rotor shaft, this type of seal is generally only fully functional when the engine has about one-third of t

For generators, everyone is familiar with them, but their working principle is not very clear. We all know that generators are bulky machines when not in use, and they are very useful when needed. Below, let me popularize the relevant knowledge of diesel generators. What are the components that dies
