1、 ISWH Horizontal Stainless Steel Centrifugal Pump Product Overview:
ISWH horizontal stainless steel centrifugal pump is a corrosion-resistant chemical pump based on ISW. This series of pumps has excellent performance, high reliability, long service life, reasonable structure, and beautiful appearance, which is at the industry level.
2、 ISWH horizontal stainless steel centrifugal pump usage:
ISWH horizontal stainless steel centrifugal pump 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 pharmaceutical, and synthetic fiber. The operating temperature ranges from -20 ℃ to+105 ℃.
3、 Working conditions of ISWH horizontal stainless steel centrifugal pump:
1. The suction pressure is ≤ 1.6MPa, or the maximum working pressure of the pump system is ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head is ≤ 1.6MPa, and the pump static pressure test pressure is 2.5MPa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately stated when ordering, so that the overcurrent and connection parts of the pump can be made of cast steel materials during manufacturing.
2. Environmental temperature<40 ℃, relative humidity<95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm.
Note: If the medium used is with small particles, please indicate it when ordering so that the manufacturer can use wear-resistant mechanical seals.
4、 Horizontal stainless steel centrifugal pump product features:
Smooth operation: The absolute concentricity of the pump shaft and excellent dynamic and static balance of the impeller ensure smooth operation without any vibration.
Drip proof: 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 runs smoothly, with almost no noise except for weak motor noise.
Low failure rate: The structure is simple and reasonable, and the key parts are of international quality; Matching, the whole machine's fault free working time is greatly improved.
Easy maintenance: Replacing seals and bearings is simple and convenient.
More land saving: The exit can be arranged in three directions: left, right, and up, which is convenient for pipeline layout and installation, saving space.

7Preparation before starting the horizontal stainless steel centrifugal pump:

1. Test whether the motor rotation is correct. When viewed from the top of the motor towards the pump, it rotates clockwise. The test time should be short to avoid causing mechanical tightness
Seal and wear.
2. Open the exhaust valve to fill the entire pump body with liquid, and then close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Manually rotate the pump to allow lubricant to enter the mechanical seal end face.
5. High temperature type should be preheated first, with a heating rate of 50 ℃/hour to ensure uniform heating of all parts.
start:
1. Fully open the inlet valve.
2. Close the valve of the discharge pipeline.
3. Start the motor and observe if the pump is running correctly.
4. Adjust the opening of the outlet valve to the desired operating conditions. If the user has a flow meter or pressure gauge installed at the pump outlet, the outlet should be adjusted by adjusting it
The valve opening allows the pump to operate at the rated point listed in the performance parameter table. If the user has a flow or pressure gauge installed at the pump outlet, it should
By adjusting the opening of the outlet valve and measuring the motor current of the pump, the motor can operate within the rated current, otherwise it will cause the pump to overload
Run (i.e. high current operation) until the motor burns out. The opening size of the outlet valve that is adjusted correctly is related to the working conditions of the pipeline.
5. Check the leakage of the shaft seal. Normally, the mechanical seal leakage should be less than 3 drops per minute.
6. Check that the temperature rise at the motor and bearings is ≤ 70 ℃.
parking:
1. The high-temperature type should first cool down, with a cooling rate of less than 10 ℃/minute, and then lower the temperature to below 80 ℃ before parking.
2. Close the valve of the discharge pipeline.
3. Stop the motor.
4. Close the inlet valve.
5. If parking for a long time, the liquid in the pump should be drained completely.
