A steam boiler is an industrial boiler that heats water to a certain parameter and generates high-temperature steam. Water is heated into steam in the drum, and the furnace gives out heat, which is the principle of a steam boiler. Steam boiler belongs to special equipment. Boiler design, processing, manufacture, installation and use must be supervised by the technical supervision department. The user can only use the steam boiler by obtaining a certificate of use of the boiler. According to fuel (electricity, oil, gas), steam boiler can be divided into three types: electric steam boiler, fuel steam boiler and gas steam boiler. According to the structure, vertical steam boiler and horizontal steam boiler can be divided into small and medium steam boilers. Double-return vertical structure and large-scale steam boiler are mostly three-cycle horizontal structure. Steam boiler scale inhibitor is a composite product composed of organic phosphonic acid and polycarboxylic acid, which has high corrosion inhibition and scale inhibition. After washing the gas steam boiler, the water distribution tank becomes the water wall bottom box and the temperature resistance is very good, which can be effectively applied to the water treatment of the low pressure boiler. Gas-fired steam boilers are suitable for corrosion and scale inhibitors, as well as for seawater desalination, distillation and automobile water tanks. The use of scale inhibitors in steam boilers can effectively suppress copper tubes and carbon steel composite components in the process; anti-F E3, Cu 2 accelerates corrosion resistance. The scale inhibitor used in gas-fired steam boiler is the guarantee of the safety of the equipment, it can be easily removed completely and at the same time reduce, the operation is simple, safe and reliable. The scale inhibitor used in gas-fired steam boiler is simple, can be discharged after neutralization, safe and environmentally friendly. It can reduce the use of scale inhibitors to maintain the performance of gas-fired steam boilers, which is conducive to the direct use of users and regular cleaning and maintenance of gas-fired steam boilers, saving equipment maintenance costs. According to the specific operation conditions of gas-fired steam boiler, descaling is simplified and easy to install and operate.

To introduce steam boiler 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.
