The hydraulic cylinder is small in size and light in weight, so the inertial force is small. When suddenly overloaded or parked, no big impact will occur. It can automatically adjust the traction speed smoothly within a given range, and can complete the speed regulation. The commutation is simple, and the conversion between the rotation of the working mechanism and the linear reciprocating motion can be completed more conveniently without changing the rotation direction of the motor. The hydraulic pump and the hydraulic motor are connected by oil pipes, and they are not severely restricted by each other in spatial arrangement. Because the oil is selected as the working medium, the relative moving surfaces of the components can be lubricated by themselves, with small wear and long service life. Check the hydraulic system once every day. Including check the motor operation, hydraulic pump operation, each solenoid valve is sensitive, etc. If there is an anomaly, deal with it immediately. Otherwise, it shall not operate. Regarding the determination of the output speed of the electric equipment, when the valve has no strict requirements for its opening and closing time, the slower speed should be selected as far as possible.
Because of the unnecessary faster speed, the motor power will be required under the same torque, which will not only waste energy, improve the project cost, but also make the volume of electric equipment waste in many aspects. At present, the electric equipment developed by ourselves in China has a small number of motor specifications (generally 2-3 specifications) designed and equipped in each frame number, and the speed ratio range of gear pair and worm gear pair in the main transmission is limited, so the torque and speed sub-gears of each frame number are not many. If the axial force of the valve is borne by the electric equipment (I. e. the valve stem nut is in the electric equipment), the thrust value of the electric equipment is not allowed to exceed the promised value of the electric equipment.
According to the principle diagram of the hydraulic system to analyze the problems of the hydraulic transmission system, find out the parts and causes of the problems, and put forward the way to eliminate the problems. The hydraulic system diagram analysis method is a super-common method used by engineers and technicians at present. It requires people to have a certain foundation of hydraulic knowledge and be able to understand the hydraulic system diagram and grasp the name, function, principle, structure and performance of the components represented by various graphic symbols. With such a foundation, it is very simple to compare and analyze and judge the faults in combination with the action cycle table. Therefore, carefully studying the basic knowledge of hydraulic pressure and grasping the hydraulic schematic diagram are super powerful helpers for fault diagnosis and removal, and are also the foundation of other fault analysis methods. Demand carefully grasped.
