Circulating water pump ISG single-stage clean water pump manufacturer pipeline pump

1ISG single-stage clean water pump manufacturer for circulating water pumpProduct Overview:

The ISG single-stage single suction vertical pipeline centrifugal pump is designed by Shanghai Bangpu Pump Industry Manufacturing Co., Ltd. and domestic water pump experts using an excellent hydraulic model, adopting the performance parameters of the IS centrifugal pump, and cleverly combining them on the basis of a general vertical pump. At the same time, suitable hot water, high temperature, and corrosive chemical pumps and oil pumps are dispatched based on the ISG type according to different operating temperatures, media, etc. This series of products has the advantages of high efficiency, energy saving, low noise, and reliable performance.

IIISG single-stage clean water pump manufacturer for circulating water pumpFeatures:

1. The pump is a vertical structure with the same inlet and outlet diameters and located on a unified centerline. It can be installed in pipelines like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors.

2. The impeller is directly mounted on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth pump operation and low vibration noise.

3. The shaft seal adopts mechanical seal or a combination of mechanical seals, using imported titanium alloy sealing rings, medium-sized high-temperature resistant mechanical seals, and hard alloy materials for wear-resistant seals, which can effectively increase the service life of mechanical seals.

4. Easy installation and maintenance, no need to disassemble the piping system, just remove the pump coupling nut to extract all rotor components.

5. Pumps can be operated in series or parallel according to the requirements of flow rate and head.

6. Vertical and horizontal installation of pumps can be adopted according to the requirements of pipeline layout.

IIIReasons for fixing obstacles and troubleshooting methods:

Pipeline pump malfunction phenomenon	Possible history of pipeline pumps	Troubleshooting methods for pipeline pumps
The pipeline pump is not producing water	The inlet and outlet valves of the pipeline pump are not open, the inlet and outlet pipelines are blocked, and the flow impeller is blocked	Check and remove blockages
	The direction of operation of the pipeline pump motor is incorrect, and the motor has a slow speed due to phase loss	Adjust the motor direction and strengthen the motor wiring
	Pipeline pump suction pipe leakage	Tighten all sealing surfaces and eliminate air
	The pipeline pump is not filled with liquid and there is air in the pump chamber	Open the pump cover or open the exhaust valve to exhaust all the air
	Insufficient water supply at the inlet and outlet of the pipeline pump, high suction stroke, and leakage of the bottom valve	Shutdown inspection and adjustment (this phenomenon is prone to occur when using grid connected water pipes and suction pumps).
	The pipeline resistance of the pipeline pump is too high, and the pump selection is improper	Reduce pipeline bends and reselect pumps
Insufficient flow of pipeline pump	First, check the reason according to 1	First, press 1. Exclude
	Pipeline pump pipeline, pump passage impeller partially blocked, scale deposition, insufficient valve opening	Remove the obstruction and readjust the valve opening
	Low voltage of pipeline pump	voltage stabilization
	Wear of pipeline pump impeller	Replace the impeller
Excessive current in pipeline pump	Pipeline pump used at rated flow rate	Adjust the flow rate and turn down the outlet valve
	The suction stroke of the pipeline pump is too high	Reduce suction distance
	Wear of pipeline pump bearings	replace the bearing
Pipeline pump noise and vibration	Unstable support of pipeline pump pipeline	Stable pipeline
	Pipeline pump liquid mixed with gas	Increase suction pressure and exhaust
	Pipeline pump generates cavitation	降低真空度
	Damaged pipeline pump bearings	replace the bearing
	Pipeline pump motor running under heat load	Adjust according to 5
Pipeline pump motor overheating	The flow rate of the pipeline pump is too high and it is running under load	Turn down the outlet valve
	Pipeline pump rubbing	Check and exclude
	The bearing of the pipeline pump motor is damaged	replace the bearing
	Insufficient voltage of pipeline pump	voltage stabilization
Pipeline pump leakage	Mechanical seal wear of pipeline pump	replace
	The pipeline pump body has sand holes or cracks	Welding repair or replacement
	The sealing surface of the pipeline pump is uneven	trim
	Loose installation bolts of pipeline pump	fasten

4、 Installation instructions for pipeline booster pump:

1. Before installation, it is necessary to check whether the fasteners of the unit are loose, and whether the flow channel of the pump body is abnormal or blocked, in order to prevent damage to the impeller and pump body during the operation of the water pump.

2. The weight of the pipeline should not be added to the water pump during installation to avoid deformation of the pump.

3. The foundation bolts must be tightened during installation to avoid the impact of vibration on pump performance during start-up.

4. For the convenience of maintenance and safety of use, a regulating valve is installed on each inlet and outlet pipeline of the pump, and a pressure gauge is installed on the pump outlet accessory to ensure that it operates within the rated head and flow range, ensuring the normal operation of the pump and increasing its service life.

5. After installation, pull out the pump shaft. The impeller should have no friction sound or jamming phenomenon, and the pump should be disassembled to check the cause.

6. There are two types of pump installation: rigid connection installation and flexible connection installation (see connection method).

5、 ISG vertical pipeline pumpWorking conditions:

1. The suction pressure is ≤ 1.0MPa, or the maximum working pressure of the pump system is ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head is ≤ 1.6MPa. The static pressure test pressure of the pump 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 is less than 0.1% of the unit volume, and the particle size is less than 0.2mm.

Note: If the medium used is with small particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.
