Horizontal condensing pressure lowest price 0 7 mw hot water boiler with best quality Precautions: 1. boiler control system to be used according to the instructions for correct operation. 2. boiler outfall road, drainage pipe must be connected to a sewage ditch. 3. The furnace room layout is reasonable, boiler room should always be kept dry and clean to prevent moisture control system. 4. types of fuel: natural gas, city gas, liquefied petroleum gas, light oil, heavy oil. The temperature should be in accordance with local diesel, heavy oil should be previously heated to 40 ~ 60oC. 6. Power Requirements: rated voltage AC.380V, 50Hz. Voltage fluctuations within the rated voltage range of ± 5%. Boiler installation should the installation protective earth wire. 7. Non placed around the boiler oil, gas and other flammable materials. Tank, the gas tank and the boiler room external wall footing line pitch should be more than 15 meters. When there is a specific reason to shorten the distance fire, it should be the local fire department and the relevant authorities; if using underground arrangement, the cover layer should be more than 0.5m, around the need to increase the firewall; underground, pumping anchor bolts must be tightened or other measures adopted to prevent the displacement of fritters. 8. Horizontal condensing pressure hot water boiler pipe PRECAUTIONS:

Boiler ignition How hard? Preparatory work must be done in place! We see, out of sight, the boiler provides a steady stream of power, supporting all aspects of our daily life and industrial production needs, making great contributions to urban development and social progress of civilization. When you buy the right to their own businesses boiler equipment, how to properly operate the boiler operation becomes very important. In order to ensure the normal operation of the boiler, before ignition must be strictly checked and fully prepared; to do the following seven steps before you can begin to start the ignition. A, check and adjust the water level in the boiler water level adjusting on the display of digital boiler water gauge, when the boiler water level below the normal level required, when the water level above the normal water level will have to open the drain valve timing drainage, the water level reaches a predetermined. The water level should not exceed the normal water line when the boiler for the first time (cold oven) Sheung Shui. This is because the boiler ignition, water boiler thermal expansion is likely to exceed safe water line. Once this happens, the water level should be adjusted by sewage. If the water table level and table column is connected, to check whether the valve opening meter column connected tube. If the water table glass contamination, poor resolution, and must be cleaned or replaced with new equipment. Second, the former boiler blowdown test run, the test should be done on the sewage discharge valve, the valve is fully closed after confirming good, be careful not to have leakage. Third, check the pressure gauge to check the position of the pressure gauge; boiler no pressure gauge pointer should be limited stop limiting, the staple of the staple, the pointer value from zero gauge should not exceed the predetermined allowable error. When the gauge does not meet the requirements should be promptly replaced. Note that the header gauge cock in the open position. Fourth, check the water supply system of water storage tank to check the adequacy of whether the water supply piping and valves open. Manual and automatic water supply for the test, to confirm its good performance, the correct action. Fifth, check the furnace flue damper open ventilation will begin ventilation, have induced draft fan should start induced draft fan for ventilation. If the natural ventilation flue long and winding, ventilation time is generally less than 10 minutes; the wind if mechanical ventilation, generally less than 5 minutes. Six, ventilation equipment inspection and inspection of all fuel grate transmission section condition, to remain intact, normal rotation job. Reserves the liquid fuel tank should be checked, the gas fuel check gas reserves, and while confirming the oil pressure is normal. Fuel lines, filters, fuel pumps, the valve opening and closing the pipeline should be checked to ensure that no exception. Start oil heater, oil maintaining an appropriate temperature. Check the opening and closing of the control valve to meet the requirements. Confirm alarms work properly. Check flame monitor light-receiving surface and protects the lens is clear and transparent. Restrict the chain system is normal. Seven check automatic control device close the power switch, the power indicator confirmed by the control panel is turned on. Check the medium (air) and the fuel line for each valve opening and closing state of the pipeline, which confirmed that no leakage, no abnormal. Check the water level detection device, the specified maximum and minimum water level at the limit, the ability to correctly stop the pump and start pumping. Check the opening and closing of the control valve to meet the requirements. Low water level alarm can confirm correct operation. Check flame monitor light-receiving surface and protects the lens is clear and transparent

Here's how to conserve water pump.

1, gas boiler feedwater pump failure prevention routine maintenance must be for the purpose of curing system and establish a scientific system to guide routine maintenance work to the pump.

2, the establishment of feed pump failure and replacement parts records, detailed grasp the parts damaged time so late in the component to be replaced before the life, avoid parts (such as: bearings, etc.) that is not timely after damage caused by damage to the unit .

3 occur, to strengthen the maintenance and regular checks amount of lubricating oil pump lubrication system, lubricating components in a timely manner, to avoid "dry grinding" and other conditions.

4, prior to the addition of the lubricating oil to be attention to check the quality and cleanliness of the oil addition port, to avoid the process of adding impurities into the bearing damage. Also note that in the conservation of the inspection and maintenance of the system piping to the pump, in a timely manner at plugging leaks, rust-proof coating the outside of the pipeline should always be checked for spray coating peeling off promptly at, in order to ensure that the tube corrosion path. Maintenance also need to pay attention to the inspection and maintenance of pump water treatment system.

According to instructions, "Neijiang City in 2017 and phase out coal-fired boiler desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.

We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.
