Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas refinery steam boiler (WNS10-1.25-Y.Q).
Steam boiler pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa refinery 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.
Nowadays, advanced electric atmospheric pressure boilers need to be used in industrial production as well as in daily life. However, the electric atmospheric pressure boiler is a highly operational mechatronics equipment, such as customer inspection, maintenance is not timely will result in equipment line aging, equipment oil circuit and oil pump wear and so on. Therefore, users need to pay attention to the maintenance of equipment when running boilers, then, what problems should users pay attention to in the maintenance of electric pressure boilers with good performance?
1, pay attention to stop furnace detection electric atmospheric pressure boiler in the maintenance, users should let the equipment according to the normal shutdown procedure operation to achieve slow cooling, at the same time, Users should use pot water circulation and furnace ventilation to gradually reduce the temperature in the pot and furnace. It is worth noting that when opening the door hole of the equipment, users need to pay attention to preventing the burning of steam, hot water and flue gas in the boiler.
2, note that when users maintain the insulation, the combustor and flue of the detected atmospheric pressure boiler should be separated from the total flue or the other running boiler flue. The test results are as follows: (1) the combustor and flue of the tested atmospheric pressure boiler should be separated from the main flue or other running boiler. And the flue gate should be closed tightly, and in the partition after ventilation. In addition, the blind plate used in equipment partition should have sufficient strength and hardness to avoid being bulged by high pressure medium in the operation of electric normal pressure boiler, and the partition position should be clearly indicated to avoid confusion.
3, note that the user must completely cut off the connection pipe between the vessel and the gas equipment, especially to the combustible and toxic medium equipment before the inspection of the atmospheric pressure vessel is carried out by the user of the equipment container. In addition, the equipment container not only needs to close the equipment valve, but also needs to use the blind plate of the equipment to close the valve so as to prevent the gas leakage into the container and cause the fire explosion or poisoning accident of the valve so as to cause the combustible or toxic gas to leak into the container.
Multiple protection devices take you through the oil refinery steam boiler oil steam boiler water level protection, boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. Steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection, having imported burner flame protection means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.Free Chat
