Product Overview: ISW horizontal pipeline centrifugal pump is designed with reference to the performance parameters of the Company under the ISO2858 international and national standards JB / T6878.2-93, combined with the company for many years experience in the production of the second generation of energy efficient products is an alternative SG ideal type pipeline pump, IS-type centrifugal pump, D-type multi-stage centrifugal pumps and other conventional. Series Flow range 1.5 ~ 1600m3 / h, head range 5 ~ 125m, basic type, shunt type, cut type, and other specifications. According to different media and different temperatures, material and structural changes in the flow part of the design and manufacture of the same parameters of the IRG-type heat pumps, IHG-type chemical pump pipeline, YG-type pipeline pump, so that the series gained popularity, can replace conventional centrifugal pumps used in all cases. Characteristics and uses: 1, ISG vertical centrifugal pumps, other liquids used for the transport of water and physical properties similar to water, the use of medium temperature does not exceed 80 ℃, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation , fire booster, long-distance water, heating, bathrooms and other warm and cold pressurized water cycle and other ancillary equipment. 2, IRG vertical hot water circulating pump for energy, metallurgy, wood processing, chemicals, textiles, paper and restaurants, bathrooms, hotels and other boilers, circulation of urban heating system circulating pump does not use medium temperature超过 120 ℃. 3, IHG vertical chemical pumps for textile, petroleum, chemical, pharmaceutical, health, food, oil refineries and other industrial chemical transport corrosive liquid medium temperature of -20 ℃ ~ + 120 ℃. 4, YG vertical pipeline pump is used to transport gasoline, kerosene, diesel and other petroleum products are transported medium temperature of -20 ℃ ~ + 120 ℃. First, the main purposes: 1, ISW horizontal water pump for conveying water and the physical and chemical properties similar to water or other liquids for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance transmission, HVAC refrigeration cycle, bathroom, heating and water circulation and equipment for pressurized, temperature T≤80 ℃. 2, ISWR horizontal heat pumps widely used in: metallurgy, chemical, textile, paper, as well as hotels and restaurants and other boilers, circulation of urban heating system, ISWR type temperature T≤120 ℃. 3, lSWH horizontal chemical pump for conveying solid granule, corrosive, liquid viscosity similar to water for petroleum, chemical, metallurgy, power, paper, food and pharmaceutical and synthetic fiber and other departments, the use of temperature -20 ~ C ~ + 120 ℃. 4, lSWB horizontal pipeline oil transport gasoline, kerosene, diesel and other oil products or use flammable, explosive liquid, is transported medium temperature of a 20 ~ C ~ + 120 ℃. Second, the horizontal pipeline pump working conditions: 1, the suction pressure ≤1.6MPa, or maximum working pressure pump system ≤1.6MPa, ie pump suction pressure + pump head ≤1.6MPa, hydrostatic test pump pressure of 2. 5MPa, please specify when ordering system work pressure. 1.6MPa working pressure pump system should be greater than in the order presented separately, in order to manufacture the pump flow section and a coupling portion using steel materials. 2, ambient temperature <40 ℃, relative humidity <95%. 3, the transmission medium volume fraction of solid particles of not more than 0.1% per unit volume, particle size <0.2mm. Note: If using the medium with small particles, please specify when ordering, so that manufacturers use wearable mechanical seal. Three horizontal pipeline pump Features: smooth operation: absolute concentricity and impeller excellent static and dynamic balance shaft to ensure smooth operation, no vibration. Leak: carbide seals of different materials to ensure the transportation of different media leaks. Low noise: two low-noise pump bearings under stable operation, in addition to the motor sounds weak, almost no noise. Failure rate: The structure is simple and reasonable, a key part of a world-class quality; supporting, the whole time between failures is greatly improved. Easy maintenance: Replace the seals, bearings, simple and convenient. More space: exit to the left, right, up three directions for easy piping installation, save space. Fourth, horizontal pipeline pump start and stop before starting to prepare: 1, the test motor rotation is correct, from the top of the motor to rotate clockwise as viewed pump, test time should be short, so as not to dry mechanical seal wear. 2, playing 幵 exhaust ^ liquid fills the pump, to be filled exhaust valves closed. 3, check all parts are normal. 4, hand plate moving pump lubricating fluid into the mechanical seal faces Peng. 5, the high temperature should be preheated Peng, a heating rate of 50 ℃ / h, in order to ensure uniform heating departments. Start: 1, full inlet valve. 2, close spit pipeline valves. 3, the starter motor, to observe whether the pump is running positive Jue. 4, adjusting the outlet valve 幵 degrees required conditions, such as a user in the pump outlet is equipped with flow meter or spirit gauge, should be made by adjusting the pump outlet valve of the operation on the maxillary 幵 point performance parameters listed in the table, such as Users equipped with a flow meter or a pressure gauge at the pump outlet, the whole family should exit door by adjusting the degree 幵 measured 璗 pump motor current, the motor runs at rated current, otherwise it will cause overcrowding charge pump operation (ie, high-current operation) to the motor burned out. Just adjust the outlet valve Jian Kai 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 ≦ 70 ℃. Parking: 1, the first high-temperature cooling, the cooling rate of <10 ℃ / min, the temperature was lowered to below 80 ℃, in order to stop. 2, close spit pipeline valves. 3, stop the motor. 4, close the inlet valve. 5, such as long-term parking, should the pump liquid exhausted. Fifth, the maintenance of a horizontal pipeline pump, running maintenance: (2) the inlet pipe must be filled with liquid, in a long-running ban pump cavitation state. (2) Regularly check the motor current Zhi, shall not exceed the fixed jaw motor current. (3) the pump for long-term operation, due to mechanical wear, noise and vibration increases the unit, you should stop and check, if necessary, replacement of wearing parts and bearings, overhaul period is generally one year. 2, the mechanical seal maintenance: (1) mechanical seal lubrication should be clean and free of solid particles. (2) non-mechanical seals work in the case of dry grinding. (3) Starting preceded plate moving pump (motor) a few times, so as not to cause a sudden start graphite ring fracture damage. (4) seal leakage allowance 3 drops / min. Otherwise it should be checked.
