NL drilling mud / dredging mud pump / submersible slurry pump / Shanghai mud pump DGmac

Product Description: NL Vertical sewage mud pump is single-stage single-suction vertical centrifugal pumps, the main components volute, impeller, pump base, pump casing, the support cylinder, motor base, motor and other components. The volute pump seat, motor base, impeller nut is cast iron, good corrosion resistance and easy processing. Impeller for three a single park chord bending leaves, optional semi-closed impeller and malleable iron, high strength, corrosion-resistant; easy to process, through the good, high efficiency. In order to reduce weight and reduce the amount of turning the pump shaft manufacturing quality carbon steel, cold-drawn steel round bar. Pump seat equipped with four skeleton oil seal and bushings prevent shaft wear and prolong the life of the shaft. NL Vertical sewage mud pump can be vertical or inclined to use, small footprint, volute to be buried in a working medium, easy to start, without diversion, the rotation from the direction of the motor tail to see the work in a clockwise direction. The Switchboard length available in various specifications according to the application in order to use the unit chosen according to local conditions. NL Vertical sewage mud pump disassembly install: demolition: 1, disassemble the motor or fixed plate, outlet pipe. 2, disassemble volute and impeller nut, light pry the impeller on the back, the dissolution of the key impeller. 3, demolition driven coupling half, before removing the key, then the motor base removal, separation of the support cylinder. 4, demolition the pump seat with the support cylinder bolts to separate them. 5, remove the sleeve and the bearing from the shaft. Second, the installation: 1, check if there are defects on all parts, pad of paper on both sides should be coated with a layer of workbooks butter, plus two-thirds of the butter in the bearing. , Skeleton oil filling must be filled butter into the pump seat, and then mounted on the bearing. 3 O-ring on the sleeve interior butter. 4, for installing the seat in the motor, put a pad of paper, oil deflector mounted on the shaft support cylinder with screws. 5, placed on a pad of paper, mounted on bearings, bushings, keys, pump base and impeller, tighten the impeller nut hand rotation of the impeller, convey dynamic and flexible and can be. , Put a pad of paper mounted on the pump casing with screws and mounted on the filter. Then hand Stubbs impeller rotation flexibility can. 7, the pump shaft installed on the keys and driven coupling on the motor shaft fitted key initiative couplings, motor and motor housing and then bolted. Asked installed and active couplings and driven coupling between the axial clearance should be 1 to 1.5 mm.
