ISW horizontal centrifugal pump Product Overview: ISW horizontal single-stage single-suction centrifugal pump performance parameters IS single-stage single-suction centrifugal pump and horizontal pumps a unique combination of design structure, easy to loose coupling to solve the drawbacks, product performance and stability. Products in strict accordance with international iso2858 design and manufacturing, the product seal selection carbide mechanical seal, with no leakage, stable operation, low noise characteristics. ISW horizontal centrifugal pump main features: 1. Stable operation: absolute concentricity excellent shaft and impeller static and dynamic balance, to ensure smooth operation without vibration. 2, leak: different materials carbide seal, to ensure the transportation of different media leak. 3, low noise: two low-noise pump bearings under running smoothly, except motor weak sound, almost no noise. 4, low failure rate: The structure is simple and reasonable, the key part of supporting world-class quality, the whole time between failures increased substantially. 5, easy maintenance: replacement of seals, bearings, convenient and easy. ISW horizontal centrifugal pump main purposes: 1, ISW horizontal centrifugal pump other liquids used for the transport of water and physical and chemical properties similar to water, for industrial and urban water supply and drainage, high-rise building pressurized water, fire booster , long-distance transport, HVAC refrigeration cycle, bathrooms and other warm and cold pressurized water cycle, temperature not higher than 80 ℃. 2, ISWR horizontal heat pumps widely used in: chemicals, textiles, paper, and hotels and restaurants and other boilers, circulation of urban heating system, iswr type temperature no higher than 120 ℃. 3, ISWH chemical centrifugal pump for conveying solid particles, corrosive, liquid viscosity similar to water, used in chemical, metallurgical, power, paper, food, pharmaceutical and synthetic fiber and other departments, the use of a temperature of -20 ℃ ~ + 120 ℃. 4, ISWB horizontal pipeline oil transport gasoline, kerosene, diesel and other oil products, or flammable, explosive liquid, is transported medium temperature of -20 ~ + 120 ℃. ISW horizontal centrifugal ready before starting: 1, the test motor rotation is correct, from the top of the pump motor to see the clockwise rotation, test time is shorter, so as to prevent mechanical seal dry wear. 2, open the exhaust valve so that the liquid fills the pump, to be filled close the exhaust valve. 3, check all parts are normal. 4, hand plate moving pump lubricating fluid into the mechanical seal face. 5, the high temperature should be preheated heating rate of 50 ℃ / h, in order to ensure uniform heating ministries. Starter: 1, fully open the inlet valve. 2. Close the discharge pipe valve. 3, the starter motor, observe the pump is running correctly. 4, adjusting the outlet valve opening to the required conditions, such as the user is equipped with a flow meter or pressure gauge at the pump outlet should be made by adjusting the pump outlet valve opening operation at the rated point performance parameters listed in the table, such as a user fitted flow meter or pressure gauge at the pump outlet, the outlet should be by adjusting the valve opening, measuring the pump motor current, the motor runs at the rated current, otherwise it will cause pump overload (ie high current operation) to the motor burn. Outlet valve opening tune just big and small and plumbers related conditions. 5. Check the seal leaks, mechanical seal leakage should be less than 3 drops / minute of normal time. 6, check the motor, the bearing temperature rise ≤70 ℃. Parking: 1, the first high-temperature cooling, cooling rate <10 ℃ / min, the temperature drop below 80 ℃, in order to stop. 2. Close the discharge pipe valve. 3, stop the motor. 4, close the inlet valve. 5, such as long-term parking should pump liquid exhausted. ISW horizontal centrifugal Causes and Solutions: Fault Causes to Remedy a centrifugal pump no water inlet and outlet valves are not opened, and out of line blocking, blocking the flow channel impeller inspection, removal of obstructions b motor running in the wrong direction. very slow speed motor phase motor direction adjustment, the fastening electrical wiring c. Tighten the suction tube leak sealing surface, remove the air d. Pump not filled with liquid, pump cavity pump cover open air or open the exhaust valve, drain air e. insufficient import water, suction is too high, the bottom valve leakage down to check and adjust (and network water pipe and with the use of suction prone to this phenomenon) f. line resistance is too large, improper pump selection for less pipe Road bend, re-election horizontal centrifugal flow pump less a. press 1. Cause 1. Check the press excluded b. pipeline, channel impeller pumps partially blocked, scale deposition, the valve opening insufficient to remove the blockage, re-adjust valve opening c. low voltage regulator d. impeller replace worn impeller attack rate is too large a. Use regulate the flow exceeds the rated flow off a small outlet valve b. suction lift too high Reduce c. Pump Bearing replacement of worn bearing noise vibration a. pipeline propping solid line b. liquid mixed with gas suction pressure of the exhaust c. cavitation reduce the degree of vacuum d. Bearing defective Replace bearing e. motor overload fever Operation Adjustment Press 5. motor heat a. the amount of traffic Overload run off a small outlet valve b. grazing excluded the c. motor bearing damaged Replace bearings d. Voltage Regulator insufficient centrifugal leaking a. mechanical seal wear replace b. the pump has sand hole or rupture welding or replacement c. sealing surface is not flat trim d mounting bolt tightening lax ISW horizontal centrifugal Special Note:. 7.5KW The following pumps can be equipped with isolation pad mounted directly on the basis of. When more than 7.5KW, can be installed directly with the casting base, we can use coupling plate with my unit IS isolator is installed, the installation method of isolation with isolation ISG pump matching the size, with the same size pump ISG series Isolated same dimensions. ISW horizontal centrifugal Installation instructions: 1, the unit should be checked before installation without loosening fasteners, pump runner Have blockage, to avoid damage to the pump impeller and the pump is running. 2, the installation of the pipeline should not be added to the weight of the pump, so as not to pump deformation. 3. When you install anchor bolts must be tightened, so as not to affect performance at the start of the vibration of the pump. 4, in order to facilitate the maintenance and use of safety in the import and export pipeline pump and the installation of a valve near the pump outlet to install a pressure gauge to ensure that run within the rated head and flow, ensure the normal operation of the pump, increase The service life of the pump. 5. Turn the shaft after installation, the impeller should be no friction sound or stuck phenomenon, or should check the pump apart cause. 6, pump sub rigid coupling installation and installation of two flexible coupling (see connection mode). ISW horizontal centrifugal pump working conditions: 1, the suction pressure ≤1.0MPa, or maximum working pressure pump system ≤1.6MPa, pump suction pressure + pump head ≤1.6MPa, hydrostatic test pump pressure 2.5MPa, please when ordering specify the system working pressure. Greater than 1.6MPa working pressure pump system should be presented separately in the order. In order to manufacture the pump flow portion and a coupling portion using steel materials. 2, ambient temperature <40 ℃, relative humidity <95%. 3, the transmission medium Guben particle volume content not exceeding 0.1% unit volume, particle size <0.2mm. Note: If using the medium with small particles, please specify when ordering to using wearable mechanical seal manufacturers.
