Product Overview: S, SH-type in a single-stage double-suction centrifugal pump (referred to as: S, SH type in a pump), the Department is a new type of single-stage double suction horizontal split centrifugal pump products. The pump has a high efficiency, wide range of applications, the axial force balance, long life, the open structure, easy maintenance, and quick. S, SH-type in a single-stage double-suction centrifugal pump suitable for handling a variety of cleaning or neutral or weak corrosive liquid with micro-particles. In a pump suitable for waterworks, irrigation and drainage pumping stations, power plants, industrial water supply systems, air conditioning systems, fire systems, shipbuilding industry, oil refining industry is also suitable for general use. Features and application: S-type in a pump and other types of pumps, compared with a long life, high efficiency, reasonable structure, low operating cost, easy installation and maintenance features, is fire, air conditioning, chemical, water treatment and other industries ideal pump. The design pressure of 1.6MPa pump and 2. OMPa. To meet the different requirements of users worldwide, according to the corresponding pump outlet flange ANSI, PN and IS standards selection. Pump outlet flanges are located under the pump, so that the rotor can be removed without dismantling the system piping, and easy maintenance section pump uses dual channel design to reduce radial force, thus prolonging the mechanical seal and bearing lifetime. Impeller impeller hydraulic design using the most advanced CFD techniques, thereby improving the efficiency of S hydraulic pump. Balancing on the impeller to ensure the smooth operation of S pump. Shaft diameter thick, short pitch bearing, thus reducing the deflection of the shaft, mechanical seal and extending the bearing life. Bushings can use a variety of different materials, in order to prevent corrosion and wear of the shaft, the sleeve can be replaced. Between the pump and impeller wear ring using replaceable wear ring to prevent the pump and impeller wear, easy to replace, low maintenance costs, while ensuring the running clearance and higher efficiency. You can either use the filler can also use mechanical seals, seal can be replaced without disassembling the pump cover. Bearing bearing unique body design of the bearing can be grease or oil lubrication, bearing design life of more than 100,000 hours, can also use double row thrust bearings and sealed bearings. Materials based on the actual needs of the user, S-type in a pump material may be copper, cast iron, ductile iron, 316 stainless steel, 416; 7 stainless steel, two-way steel, Hastelloy, Monel, titanium and alloy on the 20th, etc. materials. Installation 'S-type pump, there are two ways to install a horizontal mounting and vertical installation, vertical installation can reduce the area. [S, SH-type in a single-stage double-suction centrifugal pump] causes and remedy faults: Failure to eliminate a method, does not absorb water pump, pressure gauge and vacuum gauge pointer severe beating. 1. The injected water is not enough; 2. pipeline leak or instrument. 1. Beyond pump water inside; 2. Tighten the jam at the leak. Second, the pump does not absorb water, vacuum table shows a high vacuum. 1, the bottom valve did not open or blockage; 2, suction pipe too much resistance; 3, water height is too high. 1, correction or replacement of the bottom valve; 2, clean or replace the suction line; 3, lower water absorption height. Third, no water pump pressure gauge shows. An outlet road too much resistance; 2, rotating in the wrong direction; 3, impeller blockage; 4, speed is not enough. 1, check or shorten outlet road; 2, correct direction of rotation of the motor; 3, cleaning impeller; 4, to improve speed. Fourth, inadequate flow or head too low. An impeller or Peng outlet obstructions; 2, double suction seal ring wear too much, or impeller damage; 3, the speed is lower than the specified value. 1. Clean the impeller or pipeline; 2, replace damaged other parts; 3, alignment to the rated speed. Fifth, the pump consumes too much power. 1, packing too tight; 2, double suction impeller and seal friction bad; 3, the amount of traffic. 1. Loosen the gland; 2, check the reason, eliminate mechanical friction; 3, adjust the water valve, so that within the limits prescribed operation. Six pumps internal sound unusual, no water pump. A suction pipe resistance is too large; 2, water height is too high: 3, water at the air inhaled; 4, the suction fluid temperature is too high; 5, the amount of traffic and the cavitation phenomenon. 1, clean up the suction pipe and bottom valve; 2, lower water absorption height; 3, check the bottom valve Yao; reduce suction lift, blocking air leakage; 5, reducing the temperature of the liquid; adjust the water valve, so that the performance of the operation within the specified range . Seven, the pump is not normal vibration. 1, the pump cavitation; 2. Impeller uneven punch; 3, shaft and motor shaft misalignment; 4, foot loose screws. 1, adjust the water valve, so that the performance of the operation within the specified range; 2, impeller static balance correction: 3, correction coaxial shaft and motor shaft; 4, tighten the screw foot. Eight, bearing overheating. 1, bearing no oil; 2, shaft and motor shaft is not in the same center line. 1. Check and groove bearing body wash, add oil; 2. Correcting two coaxial shafts so at the same center line.
