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: The function of centrifugal pump: 6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.

Q: The water tank of the fish tank does not air out and only has the water outlet: The picture above is very clear, but I didn't say anything about it. My problem is solved. The intake pipe and the exhaust pipe are connected by the inverted T type. The intake pipe is upward, but not fixed. It can be rotated. The intake pipe can be rotated to adjust the number of bubbles

Q: What are the causes of pump shock?: 3. the water pump set screws loose, adjust the concentric, fastening the foot4. pump into foreign body, open cover overhaul5. the flow is too large or too small, adjust the equipment to control the water output

Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?: First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.

Q: Double floor sewage pump circuit diagram of a small problem: Question 4 when you need backup, you need to switch the SA switch, but where you want it. For example, when the 1# pump is running and does not reach the high water level, the 2# pump will not operate. If SA is placed in the left position, 21 and 22 are connected, and the KT is electrically delayed, and the KAB action causes the 2# pump to function. After the KAB operation, the KT will be disconnected, restored to the ready state, and also convenient for KT to restart the power on time, and also avoid the time relay to work on a long-term basis.

Q: Why can't the inlet of centrifugal pump be negative pressure?: Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.

Q: How many kinds of pumps are available and the operating principles of various pumps?: There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;

Q: How many kilograms of water pump are there in the automatic washing machine on the market?: Suitable for supporting high pressure sprayer, portable car washer. Water pump with overflow circuit. And comes with pressure switch, overflow switch double insurance

Q: Hydraulic pump displacement refers to the pump shaft what?: You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)

Q: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?: The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
