*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

*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:What's the difference between a concrete pump and a concrete pump truck?
Concrete pump is a pumping machine used in the field, while the concrete pump truck is a truck mounted pump.
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
Q:What is the difference between centrifugal pump and positive displacement pump?
The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.
Q:What is the difference between swashplate pump and crankshaft pump?
Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights the advantage of his adopted lookout!!!
Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
The spoon pipe is not a feed pump, but also is an adjusting oil inlet device of a hydraulic coupler matched with a feed pump
Q:What are the important parameters of the pump?
Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.
Q:How many square cables does the submersible pump for 7.5KW need?
I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
Q:What kind of motor does the hydraulic pump need?
Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element. Hydraulic pump according to the structure is divided into gear pumps, piston pumps, vane pumps and screw pumps.
Q:Types and differences of pumps
Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.
Q:What are the main performance parameters of hydraulic pumps?
Main performance parameters of hydraulic pump:1. Hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
