Submersible Screw Centrifugal Pump

Screw centrifugal pump auto pump is through special 3D helical blade, blade centrifugalreasoning function and volume effect of organic combination of spiral, the medium for energy.So it is with volume pump and vane pump characteristics, is the mutual combination of the two.Compared with the common impurity pump and vortex pump, has the following advantages: non blocking performance; nondestructive performance is good; the efficiency is high, and efficient wide area; flat power curve; good regulation performance; the pump suction performance; has good anti cavitation performance; but also transport of oil-water mixture without emulsion. Screw centrifugal pump is a kind of non clogging pump model, in the paper industry (delivery of high concentrations of pulp), Fisheries (transporting live fish, shrimp), sugar, food (transportingpotatoes, sugar beet massive vegetables such as), metallurgy, environmental protection(dredging silt, sand: delivery), application prospect a very wide range of chemical industry and other industries and sewage treatment operation.

Characteristics of screw centrifugal pump

1 non clog performance real: non blocking performance of screw centrifugal pump has the extraordinary. Open channel pump with high efficiency, no blocking features, conveying bulkysolid and long fiber material is more easily. Ordinary so-called non clogging pump, often in thelong fiber and solid into the channel be hooked edge blade or stranded, plugging in the import and export between, resulting in mechanical failure. A screw centrifugal impeller is not the existence of these problems. The spiral impeller itself is screwed into the soft solid, so that the filling material can not be blocked at the entrance, and the inner wall of the suction port and the impeller back design can prevent reverse thread groove fiber accumulation.

2 soft conveying medium: another advantage of spiral design is: "soft transport", namely thesolid material and with the flow, do not hit any part of the pump. The advantages in the following fields: conveying bulk material activity, can maintain its original physical state, loose material will not be torn, broken. The emulsion of oil, can maintain the state of its specific features. The suspension of the fiber, will not be twisted or winding. Fragile (weak) items such as tomatoes,fish and so on, can not be damaged.

Running curve of 3 outstanding: high efficiency = low operation cost; performance curve = steepand steady operation; low suction head = high self suction capability; power curve = smooth non overload region; structure of high speed = small

4 high solid content medium processing ability

5 the use of adjustable wearresisting lining: in the serious wear of the application case is an ideal choice, when wear after, only need to replace a lining can be, without replacing the entire shell, which is convenient and economic

Advantages of screw centrifugal pump

1, the Q-H curve is steep, the smooth operation of pump area wide, in pump complex medium condition curve of small amount of drift;

2, high efficiency, wide high efficiency area, operation, low maintenance cost;

3, the net absorption of low pressure, anti cavitation ability; stop the water level is low, the investment cost is greatly reduced;

4, the power curve smoothing ptosis, no overload region;

5, the real no jam, no winding;

6, the gentle conveying, transporting live fish can be intact, fruit, vegetables and other fragilematerial; in the activated sludge recirculation process of the sewage plant, the zoogloeadestruction only for other forms of pump 1/10;

7, can be transported with media of high solid rate, for example, can be transported with up to 18% of the rate of mud solid.

Application of screw centrifugal pump is expanding, in addition to used for the conveyance ofsolid-liquid two-phase fluid can also be used for conveying viscous fluid, experiments show that,the Reynolds number in the range of 3 * 103<Re<3.4 * 104, screw centrifugal pump andcentrifugal pump with the same efficiency, as the Reynolds number decreases, the spiral fromcompared heart pump and centrifugal pump fraction increased trend.

Q:How can you restart a corroded well water pump?
the problem with the pump not running will be the motor only.....most likely the motor rotor has rusted to the winding core of the motor ....soak it down with wd40 on the inside ...should be vent holes to spray wd40 in...try to find some way to turn rotor ....on some pumps there is a screwdriver slot on the end of the motor...if it still wont run take it to shop
Q:Water pumping work problem?
The pump will not have to work until the water drains by gravity to the level of the spout. Then, Work = Weight of water * Height of lift Find the distance, d, of the center of mass for the remaining water in the bottom 2 m of the sphere. The height of lift will then be 2m - d. The hardest part is finding the distance d to the center of mass. I don't remember how to do that.
Q:caravan wiring to water pump?
cut all the wires off and lay them on the earth
Q:Submersible pump reverse impact on the pump
The pressure is too small, the current is too large, the operation time is too long will burn out the pump!
Q:Water pump Decision : NAPA $42 or GM $165. Labor about 4 hrs plan to keep the car.?
I would go with the NAPA one, the GM one that is on the car now did not last forever either, I have had very good luck with after market water pumps for GM vehicles. 4 hours seems a little steep though......Good luck
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
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
Q:Why new water pump on Jeep making same noise?
my jeep with the 4.0 ate 3 water pumps,The belt can also mimic the noise of a bad pump,spray some brake cleen on the belt as it turns and if the noise goes away its the belt. ase tech
Q:who can recommend me some good water pumpS?
Water pump. ( Pond ) Sump pump. ( Flood prevention ) Auto water pump. ( Radiator ) What is the specific purpose of the pump.
Q:how do you change a water pump and on 2002 pontiac grand am gt?
type type in your info and look for a how to tyhey have many there an dother guy layed it out pretty well
Q:what kind of pump can pull water from 50ft away?
None. Atmospheric pressure is equivalent to about 10m of water height = 30ft. When a pump pulls water (or any liquid), up a certain height of pipe, it does do by lowering the pressure. In a centrifugal pump (the most common type for handling water) the point of lowest pressure is the centre of the rotor (the eye of the pump). In order to pull water 10m up, equivalent to 30ft, the pressure at the eye of the pump would be 0, which is unattainable. Not only that, but the water will begin to boil at a certain low pressure determined by the temperature of the water. That pressure at which the water begins to boil determines the lowest pressure than can exist at the eye of the pump and is a critical design variable. There are several ways to circumvent the problem of pumping water higher than 30ft. One would be to install more than one pump, with one of the pumps half-way up the hill. The other would be to install one single pump, but to place it near the pond. There is a limit to how high a pump can PULL (suck) water, but there is no limit, other than the amount of pressure the pum can generate and the piping can handle, to how far up a pump can PUSH water. If you need to puch water higher, you can always buy a bigger pump.
