1： BeijingHorizontal pipeline centrifugal pumpTechnical parameters：

Flow rate: 6.3-1600m3/h
Lift: 5-150m
Speed: 980-2900r/min
Caliber: Φ 15- Φ 500
Temperature range: 0~120 ℃
2： BeijingISWmain points:

1) Low noise and energy-saving water pumps should be selected, and it is strictly prohibited to choose obsolete products.

2) The requirements for flow rate and head must be met, which means that the operating point of the pump must be kept in the high-efficiency range.
3) The selection of pumps should meet the following requirements: reliable power supply; The speed range should be within 0.75-1.0; The device has a water level control function.

Three:Shanghai horizontal pipeline centrifugal pumpThe principle:

1) When installing a pipeline centrifugal pump, the weight of the pipeline should not be added to the pump, and there should be separate supports to avoid deformation of the pump.
2) Before installation, carefully check whether there are any hard objects in the pump flow channel that may affect the operation of the pump to avoid damaging the impeller and pump body during pump operation.
3) For the convenience of maintenance and safety of use, it is installed on the inlet and outlet pipelines of the pump, and on the outlet of the pump to ensure that the pump operates within the rated head and flow range, ensuring normal operation.

Four:BeijingISWWorking conditions:

1. The maximum working pressure is 1.6MPA, which means the pump suction pressure and pump head are less than 1.6MPA, and the pump static pressure is 2.5MPA

2. Applicable medium: Solid insoluble matter with a volume content not exceeding 0.1% of the unit volume

3. The ambient temperature should not exceed 40 ℃ and the relative humidity should not exceed 95%.

Five:Beijing horizontal pipeline centrifugal pumpThe main purpose is:

1. Suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressure boosting, long-distance water supply, HVAC refrigeration cycle, bathroom warm water cycle boosting, as well as supporting various water supply equipment and boilers.

2 Suitable for metallurgy, chemical industry, textile, wood processing, papermaking, as well as hotels, bathrooms, guesthouses, boiler hot water boosting circulation, and urban housing heating circulation,
