china electric industry hot water boiler

Steam china electric industry hot water boiler pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa steam boilers, pressure gauge accuracy of not less than 2.5; equal to the rated boiler steam pressure 2.45MPa, the pressure shall not be less than 1.5. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Dial gauge diameter of not less than 100 mm, to ensure that the operator can clearly see the surface pressure indication. 2. On the dial gauge steam boiler should draw a red line to indicate the maximum allowable working pressure. 3. The steam boiler pressure gauge should be installed in place to facilitate the observation and purged, and should prevent high temperature, vibration and icing. 4. The steam boiler pressure gauge should be checked at least once every six months, to be sealed lead-sealed after calibration. 5. The steam boiler gauge connection tube not leak water and steam, otherwise it will reduce the pressure instruction value. 6. A steam boiler pressure gauge measuring range should be compatible with the operating pressure of the device under test, the working pressure is generally 1.53 times, preferably 2 times the working pressure. Steam boiler no pressure gauge, pressure gauge or pressure gauge damage does not meet the requirements. When the steam boiler pressure gauge of the following circumstances, should stop using: 1. The surface of the glass or the dial pins; Lead seal, lead seal is broken or exceeds the calibration period; when no pressure gauge pointer position is limited to the limit staple nail can not be restored, and the rank unlimited gauge pointer movement from zero data is out of range pressure layer. Poor; leak or pointer jitter in the meter; other defects affect the accuracy of the pressure gauge. The use of the accumulator: the accumulator for a hydraulic system of the machine intermittently. It may be a low speed motion or intermittent motion of the actuator, the oil reservoir of the hydraulic pump, when rapid movement of the actuator requires a large flow rate, as an auxiliary energy supply to the system together with the hydraulic pump, enabling the pump and the entire hydraulic system miniaturization, to achieve energy saving. Hydraulic shock absorber valve and the opening and closing of rapid mutation load, the system generates a pressure shock, loved one causes vibration and noise and even damage the machine. The accumulator can relax and absorb the impact pressure of the liquid. Accumulators absorb and reduce the pressure pulsation flow pulsation and various hydraulic pumps, thus reducing noise and vibration system. The function of the gas spring having a damper, the vibration can be used to walk between the car body and the wheel and other mechanical absorption. The accumulator may be balance gravity vertical actuator (hydraulic cylinder) and the potential energy absorbing load drop into hydraulic energy storage, while producing speed resistance. When the rising vertical actuator, the accumulator absorbs energy of the original release, and together with the oil pump to the hydraulic cylinders, so as to achieve balance and energy.

Horizontal pressure steam china electric industry hot water boiler protection 1. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. When the boiler pressure exceeds the vapor pressure protection rating, it is necessary to protect the chain: the furnace is shut down and stop working combustion system; it can change the nozzle, a single stage or two stage combustion, the amount of oil can be adjusted, thereby reducing the pressure, ensure the safe operation of the boiler. 2. Protection of the same pressure level of oil (gas) steam boilers, the use of multiple protection: a pressure controller typically uses two pressure controllers, electromechanical conversion device pressure signal into an electric signal. Its function is different from the high and low signal to the electrical switch, for automatically controlling an external circuit or interlock protection. Common electrical contact manometer and pressure controller can issue an alarm overpressure vapor pressure combustor and cut off, the pressure controller adjusts single or double fire burning fire based on the actual pressure, the pressure controller may overpressure the steam pressure alarm limit is reached close the burner when the limit is reached. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. 2 safety valve safety valve last line of defense to protect the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, exhaust pressure to ensure the normal operation of the boiler.

July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam china electric industry hot water boiler contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.

Preparation (1) of the electric steam china electric industry hot water boiler before use, the operator must understand how this boiler, location, performance and working methods of the various accessories. (2), check the oil combustion, and each nozzle connection, power supply and the burner, the pump, the boiler installation accessory. (3), a clear main steam valve open, after closing the normal close it. (4), water level gauge inspection, confirmation flexible water level, normal position. (5), the pressure regulator is properly tuned, regulate combustion damper.
