ZS stainless steel horizontal single-stage centrifugal pump

ZS stainless steel horizontal stamping centrifugal pump is made of stainless steel plate; medium pressure bulge welding and other advanced processes. It is the first new generation of centrifugal pump in China, which can replace traditional small-diameter IS pumps and general corrosion-resistant pumps. It has the characteristics of beautiful appearance, light structure, high efficiency and energy saving, durable and light corrosion resistance, low noise and so on.

ZS stainless steel horizontal single-stage centrifugal pump application

ZS stainless steel horizontal stamping centrifugal pump is a multifunctional product with a wide range of applications. It can transport various media including water or industrial liquids, and is suitable for different temperature, flow and pressure ranges.
Typical applications include the following:
Water supply: filtering, conveying, water delivery and pressure boosting in the water plant;
Industrial pressurization: process water system, cleaning system;
Industrial liquid transportation: boiler feed water, condensing system, cooling and air-conditioning system, supporting machine tools, acid-base transportation;
Water treatment: distillation system or separator, swimming pool, etc .;
Farmland irrigation, petrochemicals, medicine and health.

Installation conditions of ZS stainless steel horizontal single-stage centrifugal pump

ZS stainless steel horizontal stamping centrifugal pump is a direct connection of pump shaft , which is composed of pump , pump shaft and standard motor:
The pump should be installed in a ventilated and frost-proof place;
The installation of the pump should ensure that the pump is not affected by the tension of the system pipeline when in use;
If the pump is installed outdoors, a suitable cover must be provided to prevent water or condensation on electrical components;
In order to facilitate inspection and maintenance, sufficient space must be left around the unit;
Electrical wiring device should ensure that the pump is not damaged by phase loss, unstable voltage, leakage and overload;
The pump should be installed horizontally on the base, with the suction port of the pump in the horizontal direction and the discharge port of the pump in the vertical direction.

If the pressure in the pump is lower than the vapor pressure of the conveyed liquid, cavitation may occur. To avoid cavitation, ensure that there is a minimum pressure on the pump inlet side.

* Large suction H [m] can be calculated as follows:
H = Pb 10.2-NPSH-Hf-Hv-Hs.
Pb-atmospheric pressure (bar)
In a closed line it can be considered the system pressure (bar) of the closed system.
NPSH a net positive suction head (m)
It can be read on the NPSH curve corresponding to the maximum flow in the performance curve.
Hf- pipeline loss at the inlet (m)
It is the value corresponding to the maximum flow rate that may be generated in the pipeline.
Hv-liquid vaporization pressure (m)
Its value depends on the temperature of the liquid and the vaporization pressure of the liquid.
Hs- safety margin (m)
* Small 0.5 m indenter
By calculation, if "H" is positive, it means that the pump can run under the maximum suction "H"; if "H" is negative, it means that the pump must have a minimum pressure of "H" at the inlet Normal operation can only be performed with the head of the meter.
Note: The above calculations are generally not performed. The calculation of "H" is only required when the pump is used in the following cases:
1.Higher liquid temperature
2.The liquid flow rate exceeds the rated value
3.Large suction or long inlet pipe
4. System pressure is too small
5. Poor import conditions
Operating conditions of ZS stainless steel horizontal single-stage centrifugal pump
ZS stainless steel horizontal stamping centrifugal pump delivers clean, thin, non-flammable and explosive liquids that do not contain solid particles and fibers;
Liquids with a temperature between -20 C and + 100 C;
Ambient temperature * high + 40 ℃;
* 1000 meters above sea level;
System * High pressure 10bar.
ZS stainless steel horizontal single-stage centrifugal pump motor
The motor is a fully enclosed, air-cooled two-pole standard motor;
Protection level: IP55;
Insulation class: F;
Standard voltage: 50Hz 1 220V
3 380V
