ONE:
Sleigh Axial-flow Pump introduction
For the sleigh submersible axial-flow pump knowledge,may be a lot of friends are still very strange,but for its amazing working ability maybe you have heard. The sleigh submersible axial-flow pump is very powerful,during working,its flow can reach 10 to 650 cubic meters per hour,its head range can even reach 1500 meters. What makes the sleigh submersible axial-flow pump so powerful? Now we are going to analyze it.
Sleigh submersible axial-flow pump is widely used in all areas of modern industrial production. It can take the underground water to the surface,and also can make full use of river water for modern agricultural irrigation, or for people living in the plateau region,etc. Before the sleigh submersible axial-flow pump running,the suction tube and the pump are filled with liquid. After turning on the pump,the impeller begin high-speed rotating,at the same time the inside liquid also rotates. Under the action of the centrifugal force,the water in the pump shoot out from the impeller, finally flow out of the pump outlet and out of from the discharge pipe through a series of inside setting. Sleigh submersible axial-flow pump utilizes such a simple physical principle to realize its own value, which provides the power for our human production & life and productivity.
Product name: Sleigh axial-flow pump, Sleigh submersible axial-flow pump, Inclined axial-flow pump, Vertical axial-flow pump
Service life: 20years - 30years
Flow range: 300m³/h-60000 m³/h
Water head range:1m-35m
Power range:15kw-1000kw
Water outlet diameter:350QZB-1200QZB
Motor: dry motor(covered with pure copper wire) dip coating process
Mechanical seal: (double or multiple) adopt domestic first-class brand Sichuan Riji or import brand
Bearings: adopt domestic first-class brand Wafangdian
Impeller: generally adopt 2Cr13 or stainless steel for highly corrosive water quality 304, 316, 316L, etc
Pump shaft: 2Cr13 and other materials, and customized according to the pump type and using condition
Protection equipment: relevant protection can be assembled according to the customer’s required, such as motor winding overheating protection, bearing overheating protection, water inlet protection for oil cavity, water inlet protection for motors, water inlet protection for junction box.
Zhonglan Axial Flow Pump performance:
performance: motor drives the water pump is the dry-type fully closed submersible three-phase asynchronous motor,which can be immersed in water for long time and has a series incomparable advantages of the traditional pump unit. the motor and the pump constitute a whole part, it is easy and quick to install on site, no need to carry out the assembly process of time-consuming & labor-consuming motor transmission and axis . Because of underwater operation, it can greatly simplify the real geotechnical and building structure engineering of the pumping station, reduce the installation area, and save engineering cost by 30 ~ 40%. 4. Low noise,no high temperature in the pump station,improved operating environment. Building a full underground pump station according to the requirement keep the surface environment of ground.
Product use:
it can be used in farmland irrigation and drainage, also in industrial and mining docks, city construction,water supply,water supply and drainage of power station,amusement park.
TWO:
Sleigh axial flow pump: the reasons of sleigh submersible axial flow pump mechanical seal leakage
The sleigh submersible axial-flow pump mechanical seal leakage may be caused by the abrasion between moving ring surface and static ring surface of mechanical seal, there are 6 reasons for this abrasion:
too tight: check the moving ring surface and static ring surface of mechanical seal,if there are serious charred and deep blackened traces,and seal rubber hardening or loss of elasticity and other phenomena,this is caused by over-tighting. Solution: adjust the mounting height, pull the spring with a screwdriver after installation of impeller. The spring will reset after the release because of its strong tension. Let it have a distance of 2-4mm
too loose:check the moving ring surface and static ring surface of mechanical seal, the surface has a very thin layer of scale(can be able to erase), this is caused by the loss of spring elasticity and poor assembly, or by the axial movement of the motor.
water quality with particles: The poor water quality,containing small particles and high content of hydrochloride in the medium cause abrasive materials and wear the mechanical seal plane or strain the surface, and then form groove & ring groove and other phenomenon. Solution: improve water pressure or medium,change the mechanical seal.
without water causes dry grinding damage:this phenomenon is more commen in the bottom valve installed in the form of negative pressure at the inlet, air in the pipe inlet, and there is air in the pump chamber, after turning on the pump, the friction of the mechanical seal running at high speed produces high temperature, unable to get cooling, check the mechanical seal, the spring tension is okay, the friction surface is charred and blackened, the rubber becomes hard and cracked. Spolution: empty the air inside the pipe and pump chamber, change the mechanical seal.
: cavitation corrosion mainly occurs in hot water pumps. Due to the medium is hot water, steam is produced when the water temperature is too high. The steam in the pipeline enters into the pump chamber and can not be excluded,resulting in water shortage and failure of the seal dry grinding. Solution: installing automatic exhaust valve,change the mechanical seal.
problem: the pump cover may not be mounted flat during the installation,making the shaft and the pump cover are in the non-vertical,which caused the static plane and the moving plane can not meet properly, in a short time after turning on the pump,causeing the pump’s unilateral wear and seepage. Solution:remove it and reinstall it,check if the pump cover is installed flat.
THREE:
The voltage and flow of Zhonglan Sleigh submersible axial-flow pump are rated. Under this condition, if the pump is continuously operated for 1-2 hours,,the pump running will reach a stable state. The performance test of sleigh submersible axial flow pump starts from the minimum point of power. For mixed flow pumps,axial flow pumps,or whirlpool pumps,the valve should be fully running from the start. That is the difference in the beginning. During the measurement period ,13 measurement points should be taken, and the measurement points should be evenly distributed across the whole performance curve. Each point should be measured at a time interval to ensure that the point reaches a stable state.
According to the professional introduction, from the perspective of measurement of sleigh submersible axial flow pump,”three-phase submersible pump should read three-phase current,input power,power frequency,speed tolerance,water head range and flow value. Single-phase submersible pump for split phase starting and capacitor start motor should read input power, stator main winding current, power frequency,speed tolerance,water head range and flow value, for capacitor running and capacitor start running motor should read input power,stator main winding current and stator assistant winding current,power frequency,speed tolerance,water head range and flow value.”
FOUR:
With the development of electric power technology, there are more and more types of submersible pumps,it is inevitable that submersible pumps vibrate during running. The reason for vibration of sleigh submersible axial-flow pump are as follows: submersible axial-flow pump rotor is unbalanced in the manufacturing process,pump and pump shaft is at different center,collision and friction occur between rotor and stator. 2. Being used for a long time cause wear and aging,impeller loosing, bearing damage or bearing clearance. 3. There are sundries in the pipe inlet and impeller and the foundation of the submersible axial-flow pump is fixed not stable,which cause resonance strengthening. sleigh submersible axial-flow pump working to promote the flow,accompaning eddy current and cavitation arise vibration inevitably. It can be seen that sleigh submersible axial-flow pump vibrates is not necessarily a problem,can be checked by above methods.

第三类 Sewage Pump
12、
Submersible Sewage Pump
Sewage pumps are used more and more widely. From the original simply used to transport water to be able to transport a variety of sewage,such as daily life sewage,industrial sewage,construction site drainage,the liquid feed,etc. It plays a very important role in the municipal engineering ,industry,hospital,construction,hotel,water construction and other industries.
Attentions of submersible sewage pump:
(1) When humidity sensor or temperature sensor gives a alarm, or the pump body vibrates during working, or there is abnormal noise, or the water pressure on the output drops, or electricity consumption increased significantly, the submersible sewage pump should be stopped immediately for maintenance.
(2) When some submersible pump without good sealing immersed in the water for a long time, even not start to use, the insulation value will gradually decline, eventually can not be put into use, this declined time is even shorter than the time of submersible sewage pump constantly working in the water and then it has already shown the insulation disappeared. Therefore, the spare submersible pump in the suction tank are not actually effected. If the conditions allowed, put the pump on the shore and keep it dry. When one of sewage water pump in operation has problems, stop it immdiately and raise it up, put the spare pump into the tank.
(3) The submersible pump should not be turned on or off frequently, otherwise the service life of pump will be affected. When the submersible pump stops, the water in the pipeline attacks backflow, if you turn on the pump again that will cause the pump is overloaded, and accept the unnecessary shock loads; if you turn on or off other pumps too frequently, it will damage the parts with poor shock tolerance and bring damage to the whole pump.
(4) When the pump turning off, it can not be re-started till the motor is completely stopped.
(5) Pls cut off the power supply when you check the pump.
(6) During the pump working, do not wash things, or swim, or release livestock into the water in the near, to avoid the electric accident.
Characteristics of Zhonglan submersible sewage pump
Adopted advanced technology, strong sewage discharge capacity, no blocking, can effectively pass through solid particles in diameter φ30～φ80mm.
The tearing mechanism can tear and cut off the fibrous materials, and then discharge smoothly, no need to add filter net in the pump.
The design is reasonable, the matching motor power is small, the energy saving effect is remarkable
The mechanical seal with the latest materials can make the pump run safely for more than 8000hours
Compact structure, easy to move, easy to install, can reduce project cost, no need to build pump house
Can be used in the full head range, and that ensure the motor is not overload.
The float switch can automatically control the start and stop of the pump according to the required level change, no need special supervision.
Double guide rail automatic installation system, it brings convenience to installation, people do not have to go in and out the sump.
Equipped automatic protection control box to effectively protect the product from electric leakage, water leakage and overload, improved the safety and reliability of the product.
Design technology of Zhonglan sewage sump pump
In the general centrifugal pump, the power always increases with the increase of the flow, that is to say, the power curve is a curve that rises with increase of the flow, which will bring a problem to the use of the pump:
When the pump is running at the operating point, generally speaking, the power of the pump is less than the rated power of the motor, the pump is safe;but as the pump head range decreases, the flow increases(we can see from the pump performance curve), and the power increases.
When the flow exceeds the designed operating point flow and reach a certain data, the input power of the pump may exceed the rated power of the motor, causing motor to overload and burned.
When the motor is overloaded,either the protection system stops the pump running, or the protection system fails to burn the motor.
The pump head range is lower than the designed working point head, it is often encountered in practice.
One situation is in the selection of pump, the pump head range is selected too high, and the actual use of the pump is to reduce the use of the head range.
Another situation is, the pump operating point is not easy to be determined in the use, in other words, the flow of the pump often need to be adjusted.
There is also a situation where the pump need to be constantly changing the location for use.
These three conditions may make the pump overload and affect the reliability of the pump. So for the pump without full head range(including the sewage pump), its range of use will be limited.
The so-called full head range characteristic(also named no overload characteristic) refers to the fact that the power curve rises very slowly with the increase of the flow rate. Ideally, when the flow increases to a certain value, the power will not rise any more, but will decrease, that is to say, the power curve is a curve with a hump. If so, we just choose the motor rate power point slightly over the hump of power value, so at zero flow to the largest flow of the whole range, no matter you run on which point, the pump power will not exceed the motor power to overload the pump, for the pump with this kind of performance, whether the selection or use, it will be very convenient and reliable.
In addition, the motor power should not be too large, which can save considerable equipment costs.
