china gas fired industry steam boiler machine prices
To introduce china fired industry steam boiler machine prices pressure gauge and hydraulic press accumulator using steam boiler pressure gauge should pay attention to: 1, rated steam pressure is less than 2.45MPa steam boiler, the accuracy of pressure gauge must not be 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The diameter of the dial of the pressure gauge shall not be less than 100 mm to ensure that the operator can see clearly the surface pressure indicator value. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. Steam boiler pressure gauges should be installed in a place that is easy to observe and wash. 4. Steam boiler pressure gauges should be checked at least once every six months, and should be sealed with lead after calibration. 5. Steam boiler pressure gauges should not have leakage of water and steam leakage in the connecting tubes of the pressure gauges of steam boilers. (4) the steam boiler pressure gauges should be checked at least once every six months and sealed with lead. 5. Otherwise, the pressure indicator value will be reduced. 6. The measurement range of the steam boiler pressure gauge should be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have pressure gauge, the pressure gauge is damaged or the installation of pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following conditions: 1, broken surface glass or dial calibration mold There is no clear paste; 2, no lead seal, lead seal damage or beyond the calibration period; 3, without pressure, the pressure gauge of the finite pin can not be restored to the limit pin, the infinite position of the gauge pointer deviated from zero data beyond the allowable pressure clothing; 4, gas leakage or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge. Purpose of the accumulator: the accumulator is used in the hydraulic system of intermittent machinery, which stores the oil output of the hydraulic pump during intermittent or low-speed movement of the actuator, and when the rapid movement of the actuator requires a large flow rate, As an auxiliary energy source, together with the hydraulic pump, the oil pump is supplied to the system, thus the oil pump and the hydraulic pump are realized. The miniaturization of the whole hydraulic device absorbs the quick opening and closing of the impact hydraulic reversing valve and the sudden change of the load. The system will produce shock pressure, the darling will lead to vibration and noise, and even damage the machine. The accumulator can mitigate the impact pressure absorption pulsation of these fluids absorb and reduce the flow pulsation and pressure pulsation of various hydraulic pumps thus reducing the system noise and vibration. The damped accumulator acts as a gas spring and can be used to absorb the vibration between the fuselage and wheels of walking machinery such as vehicles. The balanced accumulator absorbs the gravitational potential energy of the vertical actuator (hydraulic cylinder) and its load as it falls. When the vertical actuator rises, the accumulator releases the original absorbed energy and supplies oil to the hydraulic cylinder together with the pump, thus realizing the balance and energy saving.
The importance of water supply equipment Gas supply equipment continuous china fired industry steam boiler machine prices steam boiler 1. The effect of gas boiler room in the boiler room of the water supply equipment is a very important device all the boiler system. It is responsible for steam boiler feed "raw material", it can be a need to use the normal production of steam. During the operation of the boiler, the water supply equipment necessary to support synchronous operation, in order to continue to supply feed water to the boiler, the boiler can get enough water supply in normal operation safely. 2. Classification feedwater steam boiler steam boiler water supply equipment, there are two methods of water supply, water supply and electric steam-driven water supply categories. Steam-driven water supply equipment mainly refers to water vapor and reciprocating pumps, spare typically acts on the boiler water supply equipment. Another method of comparison used is an electric water supply through an electric centrifugal pump for water supply and vortex. Steam boiler during operation usually needs water supply equipment with active control function, the choice of the water level drops to a certain position to take the initiative to open pump water to the boiler, the water to a certain position but also take the initiative to stop the pump "bit" type conditioning. Boiler feed water can also be (a) water conditioning or heating condition circulated. Therefore, the gas boiler are usually equipped with an electric centrifugal or vortex pump, not equipped with the movable steam supply equipment.
"Thalia T7" The launch will greatly resolve hotels, supermarkets, enterprises and other energy problems and low nitrogen integration, and promote clean heating reform, promote the development of clean heating industry, the posture of the strong start another wave.
3 macrotaxonomy china fired industry steam boiler machine prices steam boiler fuel can be divided in accordance with the electric steam boiler, steam boiler fuel, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small single, double return the vertical structure, large steam boilers and more horizontal structure of three return. Vertical fuel gas steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. Horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving and economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.
