Maintenance measures for some safety accessories of industrial boilers

Time : 2021-06-16

(1) Safety valve

The safety valve can ensure that the boiler runs within the specified pressure range. If the steam pressure of the boiler exceeds the standard, the safety valve will issue an alarm to remind the operator to take corresponding measures.Another function is to decompress and reduce pressure to the boiler to ensure the normal operation of the boiler.

The abnormal safety valve is generally caused by leakage, internal foreign bodies resulting in non-sealing and other situations, usually can be adjusted and tested to ensure the normal operation of the safety valve.

 

(2) pressure gauge

The pressure gauge reflects the size of the steam boiler steam pressure, the operator can according to the numerical pressure gauge to adjust the boiler steam pressure, so as to ensure that the boiler in the specified range of working pressure operation.

The pressure gauge must have a special unit of measurement for regular testing, and in the process of use, the pressure gauge should be anti-freezing and anti-high temperature treatment, can not be suddenly impacted, in order to ensure the normal work of the pressure gauge.

 

(3) water level gauge

Through the water level gauge can check the height of the internal water surface of the steam boiler, the stoker can by observing the water level gauge, avoid the occurrence of abnormal boiler water too much or water shortage, to ensure the safe operation of the boiler.

Generally, it is necessary to observe the shape of the water level table, not to distort, the surface contact is smooth, easy to check the water level, and there can be no leakage and other phenomena, otherwise it is necessary to clean up in time.Daily also to do a good job of water table cleaning work.

 

(4) High and low water level alarm

If the boiler water level is below or above the limit water level, the high and low water level alarm can issue an alarm to remind the operator to deal with it and prevent the occurrence of related anomalies.

The water level alarm needs to be kept clean and has a good sealing effect. If it is not qualified, it cannot play a normal water level warning function.

 

Boiler shutdown maintenance

Generally, after the boiler is stopped, the interval is longer.After the boiler has been shut down, the soda system still carries moisture, and there will be a part of the water, over time, will cause the metal to react.Therefore, after the boiler is stopped in use, it is necessary to maintain the boiler, so that the boiler can operate more safely and increase the service life of the boiler.

There are 4 kinds of general furnace maintenance: pressure maintenance, wet maintenance, dry maintenance, pneumatic maintenance.Dry maintenance is more suitable for a long time to stop the furnace, can put some desiccant in the boiler, inside the furnace and other places, so you can keep the dry state, and put the internal water clean, remove scale, etc., close the relevant pipes and valves, put desiccant in the need, close the manhole, hand hole and so on.The desiccant should be confirmed once every two weeks. If the desiccant has lost its effect, it should be renewed.

General desiccant has calcium oxide, anhydrous calcium chloride, it is each square meter placed 2 kilograms or 3 kilograms can be.
