Characteristics of vacuum hot water boiler and atmospheric hot water boiler

The vacuum degree of the vacuum hot water boiler is an indicator of stable operation. Whether the control part of the vacuum hot water boiler fails, and the failure of the controller and the negative pressure and pressure controllers during operation is also unavoidable, such as the failure rate of the domestic controller. Higher. Whether the vacuum pump and the three-way solenoid valve work normally, because the vacuum pump and the three-way solenoid valve are not always operated, the original imported one is also prone to jam and malfunction during operation. The load can not be abrupt, the boiler load change is normal for the boiler, and the general boiler can meet the load regulation of 30%-100%. There are no leak points in the boiler body and valves and meters. At present, imported valves and instruments cannot guarantee that there will be no leakage within 3 years. These faults will cause the boiler vacuum to change. If a similar fault occurs, we should check the airtightness of the boiler, whether the control part is abnormal, whether the three-way solenoid valve is normal, check the load change, and if it is normal, check the negative pressure and pressure controller. The setting, everything is normal after the vacuum recovery, the boiler can still be used normally, otherwise it is necessary to stop the furnace for comprehensive inspection. The fault repair rate of the vacuum boiler in actual operation is higher than that of the pressurized steam boiler, and the control requirement is higher than that of the steam boiler.
The atmospheric hot water boiler only has the basic time, temperature and water level control of the boiler, and the hot water boiler controller is imported, and the failure rate is relatively low. There is no need to maintain the vacuum control equipment, no complicated control equipment, the personnel operation requirements are simpler than the vacuum boiler, the probability of shutdown maintenance is less, and the actual operation of the hot water boiler is much more stable.
