domestic cast iron boilers
Why domestic cast iron boilers always pay? Phenomenon: the pressure gauge shows the value of frequent falling, falling. Normal water pressure of the boiler must be greater than 0.8bar, replenishment cycle in 3-6 months or more. The boiler is connected to the cooling system in the room together to form the heating system. Pressure gauge is displayed on the boiler pressure value of the entire heating system, so that the replenishment is the replenishment of the entire heating system. Therefore, in most cases often pay a heating system problems that may arise, not the problem of the boiler. One reason: in the pre-commissioning of the new system heating system commissioning new air heating system more automatic exhaust valve release system results in reduced pressure, requiring multiple replenishment. Two reasons: heating system for leaks out pipe heating system or ground heat sealing leakage may occur at the interface and the leaks little leakage, since the heating boiler is in the state of the whole system is hot, so the leakage the rapid evaporation of the water is difficult to find the leak by the naked eye. If the pressure off the boiler and can not appear to find the leak, we recommend that you check the boiler leaks. Inspection method: After stopping the boiler operation, close the bottom of the heating boiler supply and return valves (the valve can ensure shutting), disconnected from the system directly to the boiler, the boiler supply water to an integer value, a period of observation to see if there are fluctuations in pressure gauge . This method may be simply determined to be a problem after the boiler or heating system piping valve leakage problem. Reason Three: The expansion tank expansion tank failures would result in failure of the boiler heating system pressure exceeds 3bar the boiler drain valve protection. Contact your dealer for a replacement. Four reasons: replenishment valve closed lax if replenishment valve closed lax and low pressure water pipe network, the system will fall in pressure when using hot water. Solution: If frequent replenishment of the situation, need to contact the service provider, check the heating system as soon as possible to avoid long-term damage to the boiler caused by replenishment.
The party hot water domestic cast iron boilers output fast enough to provide high efficiency, give us save a lot of fuel costs, and exhaust gas discharged tested in full compliance with environmental regulations on emissions of air pollutants in Henan Province. Fast boiler responsible attitude also left us with a deep impression, overhaul maintenance problems for a number of aspects of boiler operation and post, sent a very professional technical staff and our butt, fireman guide our people, for the quick sale of party, we are also very satisfied. --customer feedback
Circulation flow: domestic cast iron boilers water flow is more important to ensure the safe and stable operation of the boiler index. Circulation flow rate is too low, easily lead to heating boiler stopped working at too high a temperature, even within the riser section will have serious steam. However, if the circulation flow is too large, resistance heating boiler will increase, thereby increasing the energy consumption of the circulating pump. Therefore, when the overload operation, the actual flow of the heating boiler circulation should ensure that from 1.2 to 1.4 times the design flow rate.
Before starting the hot water domestic cast iron boilers, pay attention to things
Hot water boiler is common in our daily lives heating equipment, especially in the northern region of very wide application in our country, in the installation only to ensure strict compliance with the relevant rules of measures installed to be able to install the effect of better. The correct use of a series of hot water boiler can avoid unnecessary harm them, to ensure the safe operation of the boiler and physical safety personnel.
