Send positive work using the principle of positive pressure blower fan indoor smoke can not reach the stairs, to create the conditions for people to escape. Positive pressure blower usually installed on top of buildings, and the layers of the positive pressure valve linkage. General polluted air from the bathroom, toilet and kitchen exhaust, and fresh air from the living room into the bedroom and other areas. Initial fire damper is open, positive pressure blower starts, so the stairwell, elevator hall positive pressure state, generally dirty air from the bathroom, toilet and kitchen, and fresh air from the living room into the bedroom and other areas. Off mains power failure is that we usually use electricity. However, fire-fighting equipment fire electricity are connected. It is impossible to fire a fire-fighting equipment outages. That is to chase off responsibilities. There is positive pressure fan exhaust fan and blower. Exhaust fan is to indoor smoke discharged. Entrance is equipped with exhaust flue smoke damper, when the pipe temperature reaches 280 will automatically shut down. The positive pressure fan was sent to the outside breeze elevator room (elevator room fan), where the fire exits (fire exits fan) to play and let the front room where the fire exits positive pressure to prevent the formation of smoke into the front room and fire exits in come, there is room to ensure that the fire exits and former staff can breathe normally. Fire exits in the design of the fan pressure than the large front room. This a positive pressure air blower running gear sets and innocent tone institutions radial thrust axis (32 double row angular contact ball bearing) damage to positive pressure blower, causing the blades can not contain a fixed bit Ge, dip under the gas leaves full blockade, furnace pressure across -pa, boiler ft fire. Bearing 4-wear hydraulic oil bath lubrication. Oil system settings such as the right of furnishings and equipment: between 2 × 1000mw using ultra-supercritical unit blower fan and motor coupling and motor rigid-flex couplings, rigid-flex coupling is a truly balanced coupling, When able to install and run equilibrium error (shaft deflection and axial deformation positive pressure blower models, it is not the same as the coupling assembly and other difficulties, such as to fit the requirements of the life of it, it is necessary to correct the correction .4 outage After Francis under positive pressure blower, confirming that no run-down or reverse the situation, the oil temperature falls below 40 ° c, the hydraulic pump can run .9 curb public system (collecting compressed air systems, closed water system) into operation, etc. Mounting inlet, according to the inlet of the impeller clearance requirements, adjust the position of the positive pressure air inlet blower installed, then simultaneously fixed inlet. boilers with the biggest load duration (ie bmcr work) for the design. As shown, by the action blades, hub, petioles, thrust bearings, guide bearings, sliders, etc. .7 balance blocks bearing temperature> 100 ℃. dark fracture coverage layer of oxidation products of corrosion products, light. In addition to four storage tanks, pumps, outside the heat exchange unit, 0 water piping and insulation reincarnation are subject to the initial costs. positive pressure blower price, Watson air conditioning (certified), positive pressure blower is provided by air-conditioning plant in Texas Watson. Watson Texas air-conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs In Watson conditioning leadership with the staff warmly welcome all inquiries negotiations to create Watson conditioned a better future can also be accessed (www.wchuaxin.com/supply_details_46486070.html), for more information about the company.
