Abstract. To improve the automation degree in special working environment which contains explosive gas. We develop a new type of temperature control hydraulic sensor basically on theory and lots of experiments. As the temperature reaches about 85°C，the motion part of the inductor will stretch to a certain length, and then it will push the adjusting rod. Simultaneously，the adjusting rod will overcome the elastic force of the spring and compel the spool valve to deform, and finally the control valve port will be open, it allows the control oil of the hydraulic system to pass. At last it reaches our destination that we can make the control of hydraulic circuit be realized.

Actuator Control

Because ordinary hydraulic system exists multiple fault, power waste and hard controlling in actuators due to the complexity of actuators and variability of load. A new hydraulic system based on the load sensing technology is designed for the new type steel arch installing machine. The results of the simulation for forearm loop based on AMESim show that the designed hydraulic system is energy-efficient and load sensing function is effectively achieved, the actuator control performance is well.

Startup Performance

This paper introduces the structural principle of a new offset radial type motor. Through analyzing the kinematic characteristics of the motor piston theory, the result shows that the motor has characteristics of good startup performance at low speed, good sliding performance with sliding boots, smooth operation, low noise and so on, so the performance is superior to the general motor of low speed and high torque. Besides, comparing with other types of hydraulic motor, its lifetime increases and it is also easier to produce and repair. Moreover, beside the use of common hydraulic system, it can also be used in pure water hydraulic system under certain conditions.
