What are the composition and characteristics of the electrical system of engineering machinery

The specific composition of the mechanical system: power system: including the power machine and its supporting devices. It is the driving force for the work of the mechanical system. Such as internal combustion engines, steam turbines, water turbines and other power engines; there are machines that convert secondary energy (such as electrical energy, liquid energy, gas energy) into mechanical energy.

System composition The electrical system of a tractor is a general term for circuits composed of various electrical equipment and components. The electrical systems of most small tractors are relatively simple, generally only including generators, lights, switches and wires.

Compared with pure mechanical products, the technical performance and function of mechatronics systems are improved, which requiresThe mechanical body can adapt to it in terms of mechanical structure, materials, processing technology and geometric dimensions, and has the characteristics of high efficiency, multi-function, reliability and energy-saving, small size, light weight and beauty.

Industrial robots are composed of an electrical system and a robotic arm. The functions of each part are as follows: electrical system. The electrical system of industrial robots is divided into two parts: the control system and the drive system.

The main function is to store programs and data. The program is the basis for computer operation, and data is the object of computer operation. The memory is composed of a memory body, an address decoder, a read-write control circuit, an address bus and a data bus.

Hydraulic detection system of engineering machinery?

1. The site of hydraulic system failure of engineering machineryDetection and diagnosis: Characteristics of hydraulic system failure of engineering machinery The hydraulic transmission system is mainly composed of hydraulic pump, control valve, torque converter, transmission and power shift variable speed valve, etc. Its faults are usually manifested as weak walking or poor hydraulic clutch coupling.

2. At this time, the hydraulic system of engineering machinery needs to be tested by professionals for necessary adjustments and maintenance. According to practice, imported hydraulic pumps and hydraulic motors must be overhauled after working for 10,000 hours, otherwise the hydraulic pump and hydraulic motor may be damaged due to disrepair, which is fatal damage to the hydraulic system.

3. In terms of hydraulic transmission engineering machinery, the normal operation of the hydraulic system is a major sign of its good technical condition. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system, and correct maintenance is fundamental to the reliable operation of the hydraulic system.

4. This method is realized through comprehensive analysis and conditional judgment, that is, construction machinery maintenance personnel rely on work experience to judge the fault and the cause of failure through "seeing", "listening", "touching" and "smelling" and simple testing and understanding of the basic principles of the hydraulic system.

5. The working environment of tunnel construction machinery is poor, with more soot and dust, and high humidity. The full-load operation time of the hydraulic system of construction machinery is relatively long, and various faults will occur.
