Product Description:

Double Suction Centrifugal Pump With High Quality

Application

Single Stage Double Suction Split Case Pump is used for conveying water or the physical and chemical properties similar to water and other liquids suitable for factories, mines, urban water supply, power stations, agricultural irrigation and water conservancy.


Characteristic

Compact structure,beautiful outline,stable operation,low noise;

Both inlet and outlet of this pump are placed under the axial line,so it is unnecessary to remove the inlet and outlet pipeline and motor;

The shaft seal of water pump has fine mechanical seal and soft stuffing seal,which can be selected according to different condition by user;

The impeller is static-balance calibrated,fixed on the shaft with round nut,and its axial position can be adjustedvia the round nut;

The pump is direct drived by motor via resilient coupling,it can be drived by internal combustion engine if it is necessary.



Technical Data


Capacity50-20000m3/h
Head10-230m
Speed2900/1450/980/740/580/3500/1750/1180/890/710rpm



Material

Casing: Cast iron/ ductile cast iron/cast steel/stainless steel/duplex stainless steel

Impeller: Cast iron/ ductile cast iron/brone/stainless steel/duplex stainless steel

Shaft:C-steel/stainless steel


The rotation direction

Viewed from motor, the direction of the pump is anti-clockwise,that is the suction in the left, the discharge in the right.

The rotating direction of the type pump is clockwise, that is the suction in the right, the discharge in the left. 

Also can move the driver to another edge according to the user’s requires. Then, the rotating direction, the suction and discharge direction is in the opposite as the described above.

Q:What is LG water pump?
The LG in the LG pump should be a brand, without much practical significance.
Q:Installation position of check valve for water pump
Check valves must be installed at the pump's exit and position before the outlet control valve for servicing the check valve.Jiang Yuanyuan 1985's statement has a problem:1. On the flow of water, because the fluid is continuous and incompressible, the water in any part of the pipe will not flow as long as it is cut off in any position in the pipe.2, self suction exhaust is formed within the pump in outlet pipe, check valve installed in the inlet, because the pressure is low, is not conducive to automatically open the check valve, and its resistance, easy to form a vacuum pump and cavitation.
Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?
The intelligent controller of water pump is full of water and automatically shows the shortage of water in the lower pool. The reason is that the sensor is out of order or the line is out of contact. First of all, make sure that the upper limit of your controller is normally open or normally closed. When the upper limit is reached, does this point change? If the original upper limit position is normally open, check the switch and pump insulation.A pump is used to increase the pressure of a liquid or gas, the flow conveying machinery, and "jump" or "flow" is a homonym, is a transliteration of the English pump, is a device used to move liquids, gases or special fluid medium, which is reactive to the fluid machinery. The heart of man and animal can be said to be a natural pump, which carries blood to all parts of the body.
Q:Why does the GB/T3216 specify the pump performance tolerance as positive and negative?
Only half a year after graduation. Professional stuff is forgotten...I can't help you...
Q:Water pump is not Sheung reason
The problem you are experiencing is stressThe above answer is only considered in the case of water absorptionJust imagine, two pumps are normal work, the same suction pipe, how can there be dissatisfaction with water or vacuum state?.According to my experience analysisYour system is three sets of parallel, lift and flow should be the same, if not the same, not in this discussion, the topic should be set up.Lift is the same, that is, in two or three units at the same time, the resulting system pressurization is the same, and water will increaseBut now your traffic is increasing at two units, but it will not increase at threeYou have selected pipeline system design, in the design of head flow under single condition is constant, if the increase in open water pump, the pressure is constant, increasing water content, according to the continuity equation Q = A X V, then the flow velocity in the tube will increase;But when the third pumps, 2Q becomes 3Q, normally velocity should be larger, but the Darcy formula shows that the velocity increases, extension resistance and local resistance will be increased, and the double square, so you can open third pumps for reasoning, when the resistance effect caused by the pipeline the increase of water flow in the pipeline can not be reused, the general formula of constant current, now the whole pipeline in turbulent stateThat is, third pumps to do the work in the water and pipe wall friction in the loss, and actually did not play a role in water supplyThe solution is to increase the flow rate by increasing the water supply pipeline
Q:How do I calculate the power of the pump?
Motor Power (kw) =0.163*Q*H*K/60/EOf which: Q is the flow, unit m^3/hH is the lift, unit ME is the efficiency value of the pumpK is the safety factor, generally 1.1.
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
In fact, the key to this problem is to figure out what is frequency conversion, why frequency conversion, know this problem, we can easily understand the difference between frequency converter pump and ordinary water pump.We often say that the frequency is a frequency conversion process of the motor, the frequency of the motor to change the motor speed, so as to achieve the water pump flow head technology parameters are adjusted to control the role of.Variable frequency water pump refers to the motor, variable frequency pump should be driven by variable frequency motor pumpFrequency conversion, that is, adjustable frequency, frequency conversion motor is able to adjust the speed, adjust the flow, to achieve the purpose of energy saving, but also start small current, maintenance advantages of small workload.Ordinary water pump is to use ordinary motors to drive water pump rotation, that is called the power frequency motor. Our daily use frequency 50Hz, can not speed. Water pump adjustment flow through the valve throttling to achieve the same, so it is not energy-saving. The fear of harm in Wei Di apps
Q:The water burst how to repair?
This is used by welding and making AB calls
Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:What is a 1 inch water pump?
The caliber of the water inlet and outlet pipe is 1 inches of water pump,
