traders water tube steam boiler

But because of water quality problems, so can easily result in a fine diameter pipe scaling, or even blocked. And because of its parallel manner (e.g., by way of serial interfaces, interfaces intermediate too, the inner surface is not smooth, easier scale, and need to consider the expansion, leakage and other issues), wherein a particularly likely to cause the occurrence of scaling phenomenon unit then the cells are more prone to fouling the scaling, fouling the more easy to scale, all impurities are in many cycles in this cell block. And because the other three units in the unit after blocked, water can still walk normally, all fouling of the cell it is not easy to be found, the boiler will not prompt alarm. Until the unit due to the long dry leaking, causing the failure, the user will know, but it was too late to repair, must be completely replaced.

(4) low water level alarm

If the boiler water level is lower than the limit or over water, low water level alarm can alarm to alert the operator to process, prevention-related abnormalities occur.

Fault boiler long, short sootblower: sootblowers is essential for an important part of a boiler, its role is to purge the ash heating surface, heating surface remains clean, in order to improve the heat transfer effect, to ensure that the thermal efficiency of the boiler, to prevent the heating surface of the coking device. It points both long and short, then, the next will come to tell you what it's common faults and solutions: 1, long soot blower common failure symptoms: (1) failed to start and soot blower soot blower is not from the back. (2) leakage into the boiler soot blowers. (3) at the inner tube was sealed severely sootblower steam leakage, water leakage poppet valve lifting rod. (4) steam inlet flange sootblower steam leakage. Analysis: (1) the control part of the fault. (2) motor failure. (3) firing barrel deformation or Jam. (4) damage to the valve body and the valve seat surface binding. (4) sootblower boiler tubes, damage to the poppet valve packing. (5) an inlet flange sootblower graphite spiral wound gasket failure damaged. Treatment: (1) an electric contact personnel check and control system of the expansion power supply line La on whether the device. (2) an outer barrel furnace boiler sootblower bending portion rapidly burn local manual hand-crank or exit from the barrel as the slide bearing support readjust and corrected barrel, the barrel as serious deformation should be replaced with new of. (3) isolated after the individual valve lift system maintenance, disassembly of the poppet valve and the valve seat and the valve body is polished with a special tool maintenance, such as severe damage to the valve seat or the valve body and replaced. (4) the inner tube packing isolated after replacement of individual systems, note moderate tightening gland studs. (5) to replace the gasket flange. Preventive measures: (1) strict inspection process. (2) to strengthen the inspection, to detect problems in time.

"Fangkuai" boiler relies on its own products and technical advantages in industrial boilers and automatic control, and uses advanced Internet of Things technology, mobile internet technology, cloud computing technology, big data technology and intelligent control technology with heat sources, heat networks, and thermal users. It is highly centralized to form an intelligent cloud management and control center, which truly realizes the intelligentization of industrial boilers. "Fangkuai" remote monitoring system for boilers has improved boiler operation efficiency; "Fangkuai" boiler cloud service platform allows boilers to learn to think; "Fangkuai" boiler big data allows boiler cloud service platform to have "super brain"; " The real-time monitoring of the “Fangkuai” boiler makes the boiler problem nowhere to hide; the “Fangkuai” boiler 400 service system makes the service more convenient and faster.
