Product Description

Products Name:Horizontal Double Suction Centrifugal Pump
 

Product Description

 

Product use:

Water plant, water circulation in air conditioning, building water supply, irrigation and drainage pumping station, power station, industrial water supply system, fire fighting system, shipping industry, transportation of ordinary liquid.

Operation data

1 pump outlet diameter DN 80~800mm

2 flow Q ≤ 11600m3/h

3 lift is H ≤ 200m

4 T operating temperature ≤ 105 Degrees Celsius

5 solid particles is smaller than 80mg/L

6 the allowable working pressure below 25Mpa

7 allowable test pressure ≤ 37.5Mpa

Single stage double suction centrifugal pump structure:

Compact appearance,

1 the structure stability is good, easy to install.

2 stable operation optimization of double suction impeller design makes the axial force is reduced to the minimum, leaf type and have excellent hydraulic performance, and the precision casting, pump casing and impeller surface surface very Guanghua has significant anti cavitation performance and efficiency.

3 bearing selection of SKS type single-stage double suction centrifugal pump F and NSK bearings to ensure smooth running, low noise, long service life.

4 shaft seal adopts mechanical seal or packing seal. To guarantee running 8000 hours without leakage.

5 mounting assembly without adjustment, according to the site conditions of use. Split vertical or horizontal installation.

6 installation of self suction device, can realize the automatic water, do not need to install the valve, without vacuum pump, pump can be started without intrusion.

The scope of application:

Stainless steel plate pressing pump parts, the laser welded together, and there are a variety of grades of stainless steel can be used, so the use of SLG type pump is very extensive, mainly for conveying a variety of corrosive liquid and light, clean water, can be used for

1. Residential water supply and the booster

2. Industrial boiler feed water

3. Circulating water of air conditioning system

4. Water treatment and reverse osmosis system

5. Industrial water, food industry, medicine

Single stage double suction centrifugal pump working condition:

1. Flow range: 0.8m3/h~120 m3/h;

2. The lift range: 5.6m~330m;

3. Temperature range: -20 Degrees Celsius ~120 Degrees Celsius;

4. Conveying liquids: All kinds of clean water and light corrosion liquid;

5. Pump cavity pressure: ≤ 4.0Mpa.

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
