How to get the actuator through the winter

As the weather gets colder and colder, in order to ensure that the implementation is still able to operate, we need to take appropriate warming measures on the electric actuator, the current instrumentation "anti-freezing" is still the main means to rely on instrumentation workers inspection, encountered freezing, coagulation and other circuits, the use of outside the steam belt blowing plus knocking the pipeline method to solve the problem. But these are currently the most effective anti-freezing measures, let's take a look at what feasible anti-freezing measures.

1.choosing A Right Actuator

Depending on the purpose of the actuator installation and the geographic location of the installation. Specify the insulated room owner requirements for the instrument and submit to the manufacturer for selection processing. For example, in the northern countries and regions where there is a large temperature difference between day and night, methods such as manual timed maintenance can be selected after weighing the specific costs.

2.the Instrument Insulation Measures

Insulation with thermal insulation materials, that is, with thermal insulation materials to the instrument is easy to freeze or afraid of freezing parts of the package up. When winter comes to check, always sewage, to prevent the packing of insulation material breakage.

3.using An Electrically Heated Belts

Can use single-phase constant power electric heat tape, constant heat per unit length, the output power is not affected by the ambient temperature, the installation can be arbitrarily cut but at least retain 2.5m heating section, the outer braided layer has heat transfer and dissipation of heat and anti-static grounding effect, mainly used for pipeline and instrumentation anti-freezing heat preservation, the highest maintenance temperature of 150 ℃, the temperature of strict control of the temperature of the liquid pipeline heat tracing needs to be equipped with temperature controllers. Instrumentation accompanying heat in the sampling pipeline and other aspects of the application, instrumentation maintenance work in the trunk line from the process trunk line points down, supply and return water steam should be added to monitor the instrumentation to reduce the instrumentation of freezing conditions, its in the pipeline, instrumentation related areas of accompanying heat, anti-freezing and thermal insulation and other aspects play an important role.

The best way is to check the actuator in schedule, and make an alarm setting to make sure that the actuator is not fressing or you can save the actuator in time to reduce your cost.
