What are the advantages and disadvantages of custom hydraulic systems
1) Advantages of customized hydraulic system
Light weight per unit of electricity. According to statistics, the unit power weight of hydraulic pumps and hydraulic motors is only 1/10 of that of generators and motors, and hydraulic pumps and hydraulic motors can be as small as o. oo25N/ W, but generators and motors of the same power are about 0.03N /W. In terms of size, the former is about 12%-13% of the latter. Regarding the output force, the pump is easy to obtain a very high pressure hydraulic oil, and the hydraulic oil will produce a larger force when it is delivered to the hydraulic cylinder. Therefore, hydraulic technology has the outstanding characteristics of light weight, small size and large output power, which is conducive to the miniaturization and miniaturization of mechanical equipment and its control system for high-power work.
Flexible and convenient layout. The configuration of hydraulic equipment is not limited to the strict spatial position, according to the needs of the equipment, it is easy to connect the various parts of the system through the pipe, and has great flexibility in the layout and installation, and can form complex systems that are difficult to form by other methods.
Wide speed range. Through the control valve, the hydraulic transmission device can achieve a wide range of stepless speed regulation in operation, and the speed regulation range can reach 2000e
Work smoothly and quickly. The oil is elastic and can absorb impact, so the transmission movement of the hydraulic transmission is uniform and smooth; Easy to achieve fast start, braking and frequent direction changes. The commutation frequency of reciprocating rotary motion is up to 500 times/minute, and the commutation frequency of reciprocating linear motion is up to 1000 times/minute.
Easy to operate and control to achieve overload protection. The hydraulic system is easy to operate and control, easy to realize automatic control, remote control, overload protection, and self-lubricating during operation, which is conducive to heat dissipation and long life.
Easy automation and electromechanical hydraulic integration. Hydraulic technology is easy to integrate with electrical and electronic control technology to form a composite system of electromechanical and hydraulic integration to achieve automatic working cycle.
Easy to achieve linear movement. It is easier to achieve linear motion by hydraulic transmission than by mechanical transmission.
Custom hydraulic system design, manufacture, easy to use and maintain. Hydraulic components are the basic parts of the machinery industry, to achieve standardization, serialization, generalization, easy to design, manufacture, use and maintenance of the hydraulic system, is conducive to shorten the design and manufacturing cycle of equipment components and reduce manufacturing costs.
2) Disadvantages of customized hydraulic system
Custom hydraulic systems cannot guarantee constant ratio transmission. Due to the influence of compressibility and leakage of liquid, hydraulic technology can not strictly guarantee the constant ratio transmission.
Low transmission efficiency. The transmission process needs to be converted twice, and there is a lot of energy loss, so the transmission efficiency is very low.
The working stability is easily affected by temperature. The performance of the hydraulic system is very sensitive to temperature and does not work well at high or low temperatures. In addition, when using petroleum hydraulic oil as transmission medium, it is also necessary to pay attention to fire prevention. The cost is high. Since the manufacturing accuracy of hydraulic components is required to prevent and reduce leakage, the cost is high.
Fault diagnosis is difficult. Hydraulic components and systems are prone to system failure due to liquid contamination of hydraulic oil and other reasons, and even if failure occurs, it is difficult to diagnose.
