ISWB explosion-proof pipeline centrifugal pump
Product details
ISWB explosion-proof horizontal pipeline centrifugal pumpProduct Overview:
This ISWB explosion-proof horizontal pipeline centrifugal pump is equipped with an explosion-proof motor and a horizontal structure. It is a product developed based on the ISW pipeline pump and is suitable for underground coal mines, oil transportation, and chemical industries. Stainless steel material, cast steel material, etc. can be selected during the selection process. This model has outstanding performance and obvious advantages. Its product structure is scientific, its appearance is neat, and its service life exceeds that of previous pump styles. It was born as a leading level product in the industry.
ISWB explosion-proof horizontal pipeline centrifugal pumpPurpose:
1ISW type horizontal pipeline centrifugal pumpUsed for transporting clean water and other liquids with physical and chemical properties similar to clean water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment matching, with a temperature of t ≤ 80 ℃.
2ISWRHorizontal hot water pipeline pumpWidely applicable to boiler hot water pressurized circulation transportation and urban heating systems in metallurgy, chemical industry, textile, papermaking, hotels and restaurants, etc. The iswr type has an operating temperature of t ≤ 120 ℃.
3ISWH horizontalStainless steel pipeline centrifugal pumpIt is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for industries such as petroleum, chemical, metallurgical, power, papermaking, food and pharmaceuticals, and synthetic fibers. The operating temperature ranges from -20 ℃ to+120 ℃.
4ISWB Explosion proofISWFor transporting oil products such as gasoline, kerosene, diesel, or flammable and explosive liquids, the temperature of the transported medium is -20 to+120 ℃.
Features:
Stable operation: The positive concentricity of the pump shaft and excellent dynamic balance of the impeller ensure smooth operation without any oscillation.
Drip proof: The hard alloy seals made of different materials ensure that there is no leakage during the transportation of different media.
Low noise: The water pump supported by two low-noise bearings works smoothly, with no noise at all except for weak motor movement.
Low failure rate: The layout is simple and reasonable, and some use world-class quality; Matching, the whole machine's fault free working time is greatly improved.
Convenient repair: Replacing seals and bearings is easy and convenient.
More land saving: The exit can be arranged in three directions: left, right, and up, which is convenient for pipeline installation and saves space.

|
1. The centrifugal pump in the pipeline does not produce water
|
a、 The import and export valves are not open, the inlet and outlet pipelines are blocked, and the impeller of the flow channel is blocked.
b、 The motor is running in the wrong direction and has a slow speed due to phase loss. c、 The suction pipe is leaking air. d、 The pump is not filled with liquid and there is air inside the pump chamber. e、 Insufficient imported water supply, high suction, and leaking bottom valve. f、 Excessive pipeline resistance and improper pump selection. |
a、 Check and remove blockages.
b、 Adjust the direction of the motor and tighten the motor wiring. c、 Tighten all sealing surfaces and eliminate any air leaks. d、 Fill with liquid and open the exhaust valve to exhaust all air. e、 Shutdown of pipeline centrifugal pump, inspection and adjustment (this phenomenon is prone to occur when using grid connected water pipes or suction pumps). f、 Reduce pipeline bends and reselect pumps. |
|
2. Insufficient flow rate of pipeline centrifugal pump
|
a、 First, check the cause according to 1.
b、 The impeller part of the pipeline centrifugal pump flow channel is blocked, scale accumulates, and the valve opening is insufficient. c、 The voltage is too low. d、 Impeller wear. |
a、 First, press 1 to exclude.
b、 Remove the blockage and readjust the valve opening. c、 Stabilize voltage. d、 Replace the impeller. |
|
3. The current of the pipeline centrifugal pump is too high
|
a、 Exceeding the rated flow usage.
b、 The suction distance is too high. c、 The bearings of the centrifugal pump in the pipeline are worn. |
a、 Adjust the flow rate and turn down the outlet valve.
b、 Reduce. c、 Replace the bearings. |
|
4. Pipeline centrifugal pump noise and vibration
|
a、 The pipeline support is unstable.
b、 Liquid mixed with gas. c、 Generate cavitation. d、 The bearing is damaged. e、 The motor is running under overload and overheating. |
a、 Secure the pipeline.
b、 Increase the suction pressure and exhaust. c、 Reduce the vacuum level. d、 Replace the bearings. e、 Adjust according to 5. |
|
5. Heating of pipeline centrifugal pump motor
|
a、 Excessive traffic and overloaded operation.
b、 Rubbing. c、 The motor bearings are damaged. d、 Insufficient voltage. |
a、 Close the outlet valve.
b、 Check and eliminate. c、 Replace the bearings. d、 Stabilize voltage. |
|
6. Water pump leakage
|
a、 Mechanical seal wear.
b、 The pump body has sand holes or fractures. c、 The sealing surface is uneven. d、 Loosen the installation bolts. |
a、 Replace.
b、 Welding repair or replacement. c、 Repair. d、 Fastening. |
