Specifications
1,Single-stage single-suction
2,Axial suction centrifugal pump
3,Back-pull-out design
Min inlet pressure
Min inlet pressure depends on NPSH +0.5m safety margin + gasified pressure. It should be re-calculated the inlet pressure if one of the following happens.
*The liquid is more warm.
*The flow exceeds the nominate value.
*Suction distnace is very long or inlet pipe is very long.
*System pressure is too little.
*Inlet pressure is low.
Typical application
*Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.
*Water supply system
*Heat, air condition system
*Irrigating, farming
*Booster, constant pressure water supply
*Industry cooling, heater circulation system
*Firefighting, splitting system
*Industry transferring, drainage system
Construction
*Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base.
*Use bering cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part.
*Compacted shaft, use deep grove grease lubricated roller bearing.
*Connect pump and motro with semi-flexible coupling.
*Use standard wearable mechanical seal.
*TEFC motor, size complies to IEC standard, installation type B3.
*The dimensions is conform to ISO 2858
Specificaton
*Flow: Max 520m3/h
*Power:Max 160Kw
*Head: Max 160m
*Liquid temperature: -15°C - 110°C
*Working pressure: Max 16bar
*Inlet and Outlet diameter: Inlet diameter: DN50-DN200; Outlet diameter: DN32-DN150
Curve conditions
*Curves tolerance is according to ISO9906, Annex A;
*All curves are based on the measured value of constant motor speed 2900rpm, 2950rpm, 1450rpm or 1480rpm.
*The measurements were made with airless water at temperature of 20°C. The curves apply to a kinematic vis-cosity of 1 mm2/s (1 cst)
Features
*Back-pull-out design, without having to disurb pump body and pipelines when servicing.
*All the models only use 4 kinds of pump shafts and bearing cover, make parts exchangeable.
*Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise.
*Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time.
- Q: Water pump can not be pumped out, how to maintain water?
- Packing overheating:Due to packing too tight, the cooling water can not enter the filler, or the shaft surface damage. Measures for proper relaxation of packing and cleaning of sealing pipe are adopted. Filler wear must be replaced with new ones. Before installation, soak in the oil and rotate it in turn. The incision should be staggered so that water leakage can be reduced. Fill the last lap after installed loading pressed to cover operation for further adjustment of the tightness.
- Q: What are the basic technical parameters of the pump?
- The basic parameters of the pump, the basic parameters of the main performance parameters of pump are the following: first, water pump flow Q flow is the amount of liquid in the pump unit time delivery out (volume or quality). The volume of flow with Q that the unit is: m3/s, m3/h, l/s and so on. The quality of flow unit is expressed in Qm. T/h, kg/s and so on. The relationship between mass flow and volume flow is Qm= P Q density in P - liquid (kg/m3, t/m3), room temperature water P =1000kg/m3.
- Q: The main factors affecting the performance of centrifugal pumps
- Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..
- Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
- Q: Why does the centrifugal pump start and close first when the outlet valve is closed?
- The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,
- Q: What should be used to pay attention to the use of mechanical pumps?
- There are many kinds of pumps, such as centrifugal pumps, piston pumps, diaphragm pumps, vane pumps, gear pumps, etc.
- Q: What is the difference between centrifugal pump and self suction pump? Which is better?
- In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
- Q: What are the characteristics of the piston pump?
- main features 1 、 double plunger structure, small pressure pulsation, long life of gem ball.2 、 imported precious stones and precious stones to ensure accurate flow.3, through the RS232 interface and computer communication, can be directly controlled by the computer.
- Q: How long does the fine stone pump need maintenance? What should I pay attention to?
- Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
