The advantages and disadvantages of pneumatic transmission 1. The advantages and disadvantages of hydraulic transmission 1.4 Features of Hydraulic and Pneumatic Transmission Advantages: 1) The hydraulic equipment system has smaller volume, light, high power consistency and compact configuration at a given power. 2) It has good working stability. 3) It has a wide range of speed regulation. 4) The hydraulic transmission can be easily realized automation. 5) It can prevent from over-load. 6) The hydraulic system is easier in design, fabrication and application. 7) The hydraulic system is easier than machine equipment in doing line motion. Disadvantages: 1) Inevitable Oil leaks; 2) High working temperature; 3) High cost; 4) It is difficult to find the reasons of fault. Advantages: 1)The air can be obtained from and expelled to the atmosphere. 2) It is of low viscosity and lower pressure loss in pipes. 3) It is of low working pressure. 4) The pneumatic transmission needs easy servicing. 5) Safety Disadvantages: 1) The working stabilities are poorer than those of hydraulic transmission system. 2) The push force of pneumatic transmission is not strong enough. 3) Transmission inefficiency.
