Classification accuracy of gas steam boiler and hydraulic machines with precision introduce gas steam boiler and hydraulic classification of a gas steam boiler By Type 1, an industrial gas steam boiler: heating and for industrial production and so on. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, fired normal pressure hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.
Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
Put your ear to the copper pipe that supplies water to the boiler to see if you can hear water. Normal pressure should be between 12 and 15 psi. Boiler (oil) with a tankless hot water systemOnline chat
A water pressure gauge is important to understand. If the pressure is too low, you won't get any heat. If it's too high, you risk a dangerous explosion.
