Steam boiler feed water regulation and regulation in the boiler production run is a very important aspect . Good control and regulation , can produce high quality steam , once the improper operation or adjustment is not timely , it will affect the quality and yield of steam .

Low pressure steam conditioning systems play in controlling the temperature of the boiler deaerator production, regulate steam balancing effect , therefore , a reliable control system in operation is particularly important. If the automatic adjustment of the system fails, it will bring a lot of inconvenience to the operator . And manually adjust the operating room operating distance farther , not only increase the workload of the operator, is also likely to cause the steam temperature fluctuations.

Currently , 4 # boiler supporting the installation of PSL actuator electric actuator , because the longer the brand 's production of electric actuators , use a longer time , some parts are aging , the original manufacturers produce such models are no longer actuator parts, once the actuator failure, maintenance is very difficult.

Not long ago, the electric actuator 4 # boiler problems, to not affect the production, instrumentation section chip package to the workshop personnel in a timely manner to reflect the situation , arrange workshops and technical personnel to the scene to assist in handling . After careful study found that the actuator can not be remotely controlled while the control failure , the hand wheel is also very effective for the switching valve , thereby adjusting the actuator judgment means is normal , that is, the valve is normally called the . Taking into account the need to get rid of a lot of overall amount of maintenance and repair costs , but also affect the production of the principle of conservation of innovation, electric meter workshop decided actuator valve actuator part of the reservation , use the alternate will be the new ABB electric actuators replacement of faulty adjustment mechanism down .

This approach may seem simple, but in the maintenance encountered a new problem, the higher the new ABB electric actuator bracket matching , and because there are pipes above the barrier , so " grafting" it is very difficult. Finally, we discuss and by actual measurement , processing a suitable bracket to replace the original bracket . Packages have used two pieces of scrap three Ф20 threaded flanges and welded steel processing , so that the electric actuator to put something right after the re-set check into use. After using a period of observation , this transformation method is successful and feasible , but also to find a solution to similar problems in the future .

Production, will always encounter a variety of problems , only learn to change ideas, innovative thinking and the spirit of the principles of conservation and consumption reduction can be produced in piecemeal reform plays into practice in order to better serve production .
