A two-stage worm gearbox, has a "manual", "electric" switching device. Note: electric, you must remove the rocker arm. 2.3 WALL HANGING SYSTEM ACCESS AND SUPPORT: Then sealed wall soot blower frame structure connected to the frame seal welded to the furnace wall of prefabricated steel in the furnace wall or fixed with four bolts (M20 40). Sealing frame fitted with sealed box, sealed packing (see figure III). After the lance tube flange and threaded connections, on-site installation adjusts sweep direction, and then a round nut. Lance tube furnace by a plurality of pallet support care to avoid bending the lance tube has Φ60 5, Φ50 5, Φ38 4 three sizes for users to choose. Electrical control mechanism by the junction box, switch box, limit switch and other components. 3. WORKING PRINCIPLE: - The working principle Soot blower start, the end of the drive gear rotates together with the lance tube and eccentric rotation after a certain point of view, even the roller arm recess by the eccentric rose to ledge at the stem under the pressure, open the valve, soot blowing Start. (If equipped with a check valve, when the pressure is higher than the air pressure soot blowing medium, the check valve closes automatically stop the compressed air input) When the lance tube and then turn a certain angle, even the roller arm falls eccentric recess, the valve closes, soot blowing is stopped. (If equipped with a check valve, the check valve automatically open at this time, the compressed air to re-enter the soot blower valve) When soot blower operation fixed on a touch eccentric screw limit switch control system, power cut, to complete a soot blower soot blowing process. 4. INSTALLATION 4.1 INSTALLATION PREPARATION: All parts and components inventory and inspection; According to the instructions (Figure 3) provides mounting dimensions, check whether the furnace is consistent with the actual situation. Application of compressed air blowing lance tube and check whether the lance tube bending, bending should be checked if straightening.

5 4.2 INSTALLATION: According to the selected point of soot blowing, welding furnace pallets. Must ensure that all pallets hole centered on the same axis (in general, the furnace from the furnace wall to the inner wall of the pallet when welding: Φ60 lance tube is approximately 600mm, Φ50 lance tube is approximately 500mm, Φ38 lance tube about 400mm). (The original boiler manufacturing boiler has been installed pallet, this step can be omitted) The lance tube inserted into the furnace of the pallet. According to the position of the lance tube shown will pick wallboard welded seal frame on the wall of the furnace or four pre-engineered steel connecting bolts (M20 40) fixed to the furnace wall, so that the axis of the lance tube in a sealed box hole center. The soot blower intake valve flange and soot blowing steam (air) pipe connection (connection dimensions see figure II), gas (gas) pipeline should be able to shrink and swell with the furnace. Purge all the soot blowing pipe, welding slag removal debris. Soot blowers body in place by the top screw rings hanging below the valve fla nge and steam (air) pipe connections. The lance tube flange and hollow shaft flange hole with the lance tube screwed into the inner flange, according to the valve opening and closing position adjustment eccentric purge good position, and then the nuts securing the lance tube and put a mark on the flange and the lance tube, note the position of the nozzle. Into the gasket, the two flange connection (Note: the lance tube is screwed into the hollow shaft with the need to ensure effective to compres s the gasket (see figure III) within the flange. When used on pressurized boiler, a one-way valve, connected to compressed air. Air source can be from a compressed air or blower, as long as the positive pressure slightly above the furnace can be positive. When used in a negative pressure boiler, time to install check valves, or installed will not receive ventilation source. Power and control lines.
