Product Details
Product name: Stainless steel vertical multistage pipeline centrifugal pump
Product use:
1. LISG single stage single suction vertical pipeline centrifugal pump, Applicable industry and city water supply and drainage, high-rise building pressurized water, garden irrigation, cooling tower water, long distance water, cold and hot water circulation pressurization and ancillary equipment, medium temperature below 80 degrees Celsius.
Working conditions
1, the suction pressure ≤ 1.0Mpa, or maximum working pump system pressure below 1.6Mpa, the pump outlet pressure and pump head, pump ≤ 1.6Mpa hydrostatic test pressure suction is 2.5Mpa, please specify when ordering the system working pressure.
2, the ambient temperature of <40 degrees Celsius, relative humidity <95%.
3, the volume fraction of solid particles in the medium of no more than 0.1% per unit volume, size <0.2mm
Note:
1. If using the medium with small particles, please indicate in order, so that the wear type mechanical seal.
2. The pump pressure greater than 1.6Mpa system should be put in order. In order to manufacture pump over-current components and the connection part of the cast steel.
The scope of performance parameter:
LISG single stage single suction vertical pipeline centrifugal pump, the hydraulic model, at the same time, according to the international standard related to the design and development to become the SG series pipeline pump replacement products. The technical standards, performance parameter, test methods are effective by IS type centrifugal pump of ISO international standard, performance parameters with IS type centrifugal pump is basically the same, the performance indexes meet the design requirements.
Its performance parameter scope is:
1. Traffic: 2.5 - 400 (m3/h)
2. Head: 5 - 125(m)
3. Shaft power: 0.55 - 132 (kW)
4. Suction diameter: 20 - 200 (mm)
5. Discharge diameter: 20 - 200 (mm)
6. Performance: Frequency
7. Use: Pipeline pump
8. Pump shaft position: Edge of the vertical
9. Impeller structure: Closed impeller
10. Inhalation: Single suction impeller
11. The structure principle: Jet pump
12. Material: Cast Iron
Advantage:
LISG, LISW type pump is made by cast iron casting, is characteristic of the motor and pump coaxial, end cover into a whole, so that the pump has the advantages of compact structure, small volume, light weight, stable running, convenient installation, can completely replace the IS type, BA type and other types of centrifugal pump.
| fault phenomenon | failure cause | elimination methods |
| 1.No power supply or one or two phase power supply is needed | Check all phases of power supply and restore power supply | |
| 2.Poor contact of ac contactor and burning of coil | Repair or replace contactors | |
| can not start | 3. The power switch is not closed, malfunction or damaged | Close the switch and replace it if the power indicator does not turn on |
| 4. Thermal relay trip or damage | Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started | |
| Water level is too low | Put water in the sink | |
| The motor burned | Repair or replace the motor | |
| 1.Line is loose | Check wiring and tighten connectors | |
| 2.Frequency converter malfunction | Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. | |
| The manual is normal | 3The frequency converter is damaged | Repair or replace |
| Automatic transmission failure | 4.Pressure switch damage | Repair or replace |
| 5The pressure transmitter is damaged | Repair or replace | |
| 6.Switch failure | Repair or replace | |
| Pump non - suction pressure gauge pointer to beat violently | Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument | Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
| The pump consumes too much power | Too much flow, impeller wear | Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
