Multi-stage pump vapor recovery pump, vapor recovery pump, the pump has been certified Waugh

Multi-stage pump disassembly sequence: a, lemon under spit spit segment connecting bolts and nuts, stuffing body, bearing body in three parts on the side of the bearing between the gland to remove the bearing member B: b, unscrew the shaft round nuts, followed by removing the sheath, the bearing inner ring (bearing), a hole bearing gland, after retaining ring, remove the filler (including packing gland, packing ring and filler): c, followed by removing the shaft O-ring on the sleeve, after the balance disc and key, remove the discharge section (including the last stage vanes, gimbals, balance sets, etc.); d, removing the last stage impeller and key, remove the middle ( including vanes): in the same way at all levels in order to remove the rest of the impeller, the middle and guide vanes, until removing the first stage impeller so far: After e, unscrew the nuts and bearing bolted gland suction section and the bearing body on Remove the bearing assembly A (which should be preceded in the pump coupling Removing); f, the shaft is removed from the intake section, unscrew the shaft lock nut, turn the bearing inner ring, O-ring , bushings and gear sets, and so removed. At this point the demolition work completed, but in the above demolition process, there are some parts are connected together, under normal circumstances can be removed after unscrewing the bolts or nuts. How to repair the water pump in the winter and maintenance 1, the pump is disabled, try to put the water pump and water left inside the pipeline, and the external dirt clean, so as not to freeze water ice on the pump and pipes bursting. 2, the pump, the bottom valve, pipe and other iron castings, should the rust with a wire brush brushing, then be coated with rust before painting and then into the room to be dried or storage chamber ventilated, dry place Save. 3, with belt drive, hang to dry after washing with warm water to remove the belt in a dry place away from direct sunlight, and do not be stored in a oil, corrosion and cigarette smoke. In any case, do not make belt stained with oil, diesel or gasoline and other oils, not painted rosin and other sticky substances. 4, check the ball, as inner ring and outer wear, Kuang move, the ball wear or surface spots must be replaced. Available on the need to replace gasoline or kerosene to clean the bearing, butter, reassemble. 5. Check the pump impeller for cracks or holes, impeller retaining nut is loose, if any damage should be repaired or replaced. If impeller wear too much or has broken, the general should be replaced with a new impeller. Local damage can be welding, you can also use epoxy mortar for an impeller repair should be carried out after the general static balance test. Check the impeller clearance by grinding annulus, if more than a predetermined value, should be repaired or replaced. 6, shaft bent or badly worn, it should be repaired or replaced, otherwise it will cause wear of the rotor unbalance and related components. 7. Remove the screws come soaked in diesel fuel was clean with a wire brush, and coated with oil or butter, reinstall it with plastic wrap or put away (also soaked in diesel saved), so as not to rust or missing. Hebei Wo large industrial pump main flow single-stage double-suction centrifugal pumps, Francis pumps, wearable slurry pump, power plant desulfurization pumps, mining multistage centrifugal pump, filter feed pumps, pipes direct the pump , stainless steel chemical centrifugal pump, pump mechanical seal, diesel pump units and other products, and contract non-standard pumps and accessories design, production and processing, water treatment engineering design. Reputation first, quality assurance, prompt delivery. Welcome friends to negotiate business. DF pump is corrosion resistant stainless steel horizontal multistage centrifugal pump, suitable for conveying corrosive media, its volume of solid insoluble not exceeding 0.1% unit volume, size ≤2mm; DF type pumps are horizontal installation, the suction port level, discharge outlet vertical. Suction section of the pump, the middle section is discharged with tension bolt coupling into one. Pump by the pump, impeller, shaft, guide vanes, guide vanes sets and balance disc and other major component parts. The axial force of the rotor by the balance disc balance. Rolling bearing with grease lubrication. Seal mechanical seals and packing. In the packing of the stuffing box pass into a certain pressure of water from the water seal effect. Direction from the drive end, the pump is clockwise.
