Electric actuator
The electric actuator is suitable for the control of valves used in low temperature environment. Based on its ordinary type, the electric actuator takes corresponding measures on the material of the main box and other force parts, the material of electric control devices and wires, the material of seals, the grease, the performance and power selection of the motor to achieve the low temperature performance that the product should have. Based on the test methods and procedures of the introduced technical documents, the low temperature test was carried out on the typical seat prototype, which achieved the ideal effect and reached the The test requirements were met and the actual conditions of use were met.
Applicable temperature range
Low temperature I type temperature range -25℃~-40℃
Low temperature Ⅱ temperature range -40℃~-55℃
Note: The maximum ambient temperature of low-temperature Ⅱ type electric device shall not exceed 40℃ test process
The method is to put the electric device (with test bench) in the low-temperature freezer, and long time insulation in -55 ℃ ultra-low temperature environment, and then the relevant performance experiments, to achieve normal operation and good performance.
