Tips for Maintenance of Diesel Engine Filters
The engines of tractors and agricultural transport vehicles are all equipped with an air filter, an oil filter and a diesel filter, commonly known as the “three filters”. The working condition of the three filters directly affects the operating performance and service life of the engi...Read more -
Causes of Diesel Engine Bearing Seizure
Failure to use lubricating oil according to seasons. Different grades of lubricating oil shall be used in different seasons. Some diesel engines suffer from bearing seizure simply because low-viscosity lubricating oil is used in summer, which fails to form an oil film on the contact surface of cr...Read more -
Analysis, Handling and Prevention of Common Vibration Faults in Aircraft Transmissions
The causes of vibration in a rotating machine usually fall into four categories: imbalance, resonance, misalignment, and mechanical failure. 1. Rotor imbalance It is a common cause of vibration. Factors such as poor rotor manufacturing, accumulation of foreign objects on rotor blades, and unbala...Read more -
Selection of Commonly Used Diesel Generators
Some diesel generators are required to operate continuously for a certain period of time or frequently as the main power supply for electrical loads. Such generators are called regular power generators. Regular power generators can be classified as either regular units or backup units. In areas s...Read more -
The combination of gear reduction motor modules
In the structural design of gear reduction motor modules, it is essential to take into account the design of joint connection elements. To ensure module interchangeability, joint connections shall serve the functions of positioning and coupling. Their shape, dimensions and fits should comply with...Read more -
Design of the gear reduction motor module
How to divide modules is a key issue in the modular design of gear reduction motors. Fewer module types, a higher degree of generalization, and larger production batches are conducive to cost reduction. However, from the perspective of system connotation and extension, a comprehensive analysis of...Read more -
Fault inspection of the motor(3)
When the motor is running, there is noise. The fault occurred in the mechanical and electromagnetic parts of the motor. Here is the professional English translation of the motor fault diagnosis text, in standard technical English: The method of differentiation is as follows: run the motor first ...Read more -
Fault inspection of the motor(2)
Fuse Blown or Thermal Relay Tripped During Startup Fault Inspection Steps Check if the fuse rating is appropriate. If it is too small, replace it with a suitable one and test again. If the fuse continues to blow, inspect whether the drive belt is too tight or the driven load is excessive, check ...Read more -
Fault inspection of the motor(1)
For the troubleshooting of motor faults, various materials present a wide range of methods. From the perspective of combining theory with practice, the following specific analysis is conducted. 1. The motor fails to start. 1) The motor does not rotate and there is no sound. The reason is that th...Read more -
Prohibited Operating Procedures for Using Diesel Generators in Winter
The temperature in winter is relatively low, and there are often some minor problems when starting diesel generators. Some people often adopt incorrect methods, which can damage the diesel engine. Here are six methods that are not advisable for starting diesel engines in winter at low temperature...Read more -
Operation regulations for the two-point grounding protection device of the excitation circuit
1. The two-point grounding protection device for the stator and rotor excitation circuits is used to monitor the situation where the rotor circuit of the running generator has a permanent metallic grounding. Once the second point of grounding occurs, a signal will be generated or the generator sw...Read more -
