The impeller is static-balance calibrated, fixed with the m- uff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axle end. The pump shaft is supported by two single-column centripe- tal ball bearings, which are mounted inside of the bearing body on both ends of the pump and lubricated with grease. The dual- suction seal ring is used to reduce the leak at the impeller. Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle so it is unneccessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the clutch to it. The pump moving CCW can also be made, but it should be specially noted at order. The main parts of the pump are: pump casing(1), pump cover (2), impeller (3), shaft(4), dual-suction seal ring(5), muff(6), be- aring(15) etc.and all of them, except the axle which is made of quality carbon steel, are made of cast iron. The material may be replaced with others upon different media. S o 80 C Model S pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of water, the maximum temperature of which must not be over 80 , suitable for water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects. 150 S 78 A Outer diameter of impeller via first cut 78 Head: 78m Dual-suction centrifugal pump 150 Pump's inlet diameter:150mm ( ) (1) (2) (3) (4) (5) (6) (15) MODEL MEANING 13661725188 02 1 Check both pump and motor to see if any damages with th- em. 2 The installat ion height f the pump plus the hydraulic loss of the suck-in pipeline and its speed energy is just the NPSHa of the unit, which should bigger than NPSHr. The dimensions of the basis should be in line with those of in- stallation of the pump unit. 3. Installation sequences: The pump is driven directly by means of connecting to it via an elastic clutch. (Set up a stand additionally in case of a rubber band driving). The shaft seal is packing seal and, to cool and lubricate the seal cavity and prevent air from getting into the pump, there is a packing ring between the packing. A small volume of high- pressure water flows into the packing cavity via the tapered beard during the pump's working to act as a water seal. ASSEMBLY AND DISASSEMBLY 1 2 1. Assembly of the rotor's parts: in turn mount the impeller, muff, muff nut, packing sleeve, packing ring, packing gland, mechanical seal, mechanical seal bland, water retai ning r- i ng and bearing on the pump shaft, put on the dual-suction seal ring and then the clutch. 2. Check the outer circles of the impeller's seal and the muff on the rotor separately, the radial jumping of which should not be over the settings in the table below. Nominal diameter <50 50 120 120 250 250 500 500 800 800 1250 Jumping capacity 0.03 0.04 0.05 0.06 0.08 0.10 3 4 ( ) 3 Mount the rotor on the pump casing and adjust the impeller to have its axial position in the middle of the dual-suction seal ring in both sides and then fixed, then fix the gland of the b- earing's body with the fixing screws. 4 Put on the packing(in case of a packing seal), the paper pad on the middle opened face and the pump cover and tighten the threaded-tail conical pin first and then cover's nut. Mo- unt the packing gland, but do not press the packing too tig- htly, otherwise the muff may get heated to leave a bigger power consumption; while not too loose, or a big leak of liquid and reduced pump efficiency may re sult in . If me- chani cal seal is used, adjust the stud on the gland to ensure no leak with it. After a sse mbly, move the pump shaft with hand, it should be smooth and uniform without touch. Disassembly can be m- ade with the steps contrary to above ones. INSTALLATION 1 2 NPSHa NPSHa NPSHr 3 13661725188 03 1. Start and stop (1) Before starting, move the rotor of the pump, which should be felt light, smooth and uniform. (2) Close the water outlet valve, prime water into the pump (le- ad water by extracting with a vacuum pump in case of no foot valve). Ensure the pump full of water and no air ne- sted inside of it. (1) (2) (3) (4) 0.1 0.3 ( ) (5) 4 5 6 7 ( 20 ) (1) Place the pump on the concrete basis with built-in foot bolts, correct the levelness with the method adjusting the wedge cushi on block an d properly tighten the bolts to prevent them from displacement. (2) Grout concret e between the basis and the pump foot. (3) After the concrete gets solidified, tighten the foot bolts and check the pump's levelness again. (4) Correct the concentricity between the axles of both pump and motor to have them in a straight line. The allowed tol- erance of the non-concentricity of the outer circles of two clutches is 0.1mm and the one of the non-uniform end-face intervals along with the circumference is 0.3mm(another cor rection of which after both water inlet and outlet pipe- lines are connected and a trial movement, the above requ- irements should also be met with). (5) After finding out the rotating direction of the motor is ide- ntical to that of the pump, mount the link pin of the clutch. 4 Both water inlet and outlet pipelines should be supported by a separate stand and not by the pump body. 5 A good air tightness of the combined face between both p- ump and pipeline should be kept, especially the inlet pipel- ine, it must be guaranteed without air leak and without the poss ibility for air to be nested on the unit. 6 In general, a foot valve can be mounted if the pump is mo- unted above the water level of the water inlet so as to start the pump with priming, it can also use the way of vacuum pu- mp water leading. 7 In general gate valve and check valve are required to be m- ounted in the water outlet pipeline of the pump(unnecessary for those of a head less than 20m), with the check valve mounted after the gate valve. The above ways of installation mean the pump without a common foundation. For the pump with a common foundation, use the wedge- iron-pad between both foundation and concrete to correct the levelness of the unit, then grout concrete between them. The installation principle and requirements are the same as those for the pump without a common foundation. START STOP AND RUN (1) (2) ( ), S SERIES SINGLE-STAGE DOUBLE-SUCTION HORIZONTAL SPLIT CENTRIFUGAL PUMP 13661725188 04 (3) First close the plug of a vacuum or pressure meter, if so m- ounted on the pump, connected to the pump before starting the motor and then open it when the motor move in the nor- mal speed; next, gradually open the water outlet gate va- lve and make it smaller in case of a large flowrater or big- ger or bigger on the contrary. (4) Uniformly tighten the pressing nut on the packing gland to have liquid leak in drops and pay attention to the tempera- ture rise outside of the packing cavity. (5) When to stop the pump, first close the plug of the vacuum or pressure meter and the gate valve on the water outlet p- ipeline, then cut off the power of the motor. Open the squ- are screw plug on the lower side of the pump casing to let the residual water out to prevent frozen cracking in case of a lower ambient temperature. (6) In a long time stop, remove the pump and dry the parts and coat rust-proof grease on the processed surface. 2. Running (1) The maximum temperature of the pump's bearing must not be over 75 . (2) It is proper for the volume of the calcium-based grease lub- ricating the bearing to hold a space inside of the bearing body by 1/3 1/2. (3) Properly press the packing gland in case of a little bit we- ar and replace it in case of too much wear. (4) Take a periodic check of the elastic clutch and take care of the temperature rise with the motor's bearing. (5) During running, stop it at once when noise or other abnor- mal sound is heard to find the cause and settle it. (6) Do not raise the pump speed at will, but lowering it is all- owed. For instance, with this type of pump, the rated rotat- ing speed is n, flowrate is Q, head is H, axle power is N, lo- wered speed is n1, the flowrate, head and axle power after speed lowering are Q1, H1 and N1, respectively. Make c- onve rsion by means of the following formula. (3) (4) (5) (6) (1) 75 (2) 1/3 1/2 (3) (4) (5) (6) n Q H N n1 Q1 H1 N1 Q1=( )Q n1 n 2 H1=( ) H n1 n 3 N1=( ) N n1 n 13661725188 05 1.
