Product Description:

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 to select the pump model?
Pump selection parameter:1, lift, if the head is large, the use of multi-stage vertical centrifugal pump, if the head is small, the use of horizontal axial flow centrifugal pump2. Displacement3, suction stroke, if the suction range is short, select the submersible pump, suction distance, select centrifugal pump
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP55 represents the waterproof and dustproof rating of the motor
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
The problem is unclear and it is not clear what the question is. Is the pump open or closed or is the valve closed? Or else?
Q:What is the defection of water pump
Water pump installation of a one-way valve on it.
Q:Does the lift of pump relate to the water level of import and export?
What's the relationship?! When the inlet level is low, the head is slightly higher than the liquid level!
Q:The pump assembly and the pump are not a thing
Yes, all the auto parts are called assembly, and the pump is the same. It's called water pump assembly. Also, the pump half assembly is the water pump head.
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
Q:Submersible pump coupling, what does this coupling mean?
What is a fixed submersible pump, submersible pump installed this thing to get up you ask to buy special Songchuan pump pump they'll explain it to you.
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
1, frequency conversion water pump is based on ordinary water pump. The so-called common pump means without any automatic control device of the pump, only the pump head and the motor and a base. The power supply is switched on (default: 220/50Hz or domestic power single-phase three-phase 380V/50Hz) run off, stop. Ordinary pumps do not refer to a particular type of pump, can be centrifugal pumps, pipe pumps, vortex pumps, multi-stage pumps and other pumps commonly used.2, the variable frequency pump, is supplemented by a one-way valve, pressure tank, inverter, constant pressure water supply controller, sensor, valve or electrical components in general based on the composition of water pump with automatic function, and automatic constant pressure frequency conversion water supply device. The input power of frequency conversion water pump can be single phase 220V/50Hz or three-phase 380V/50Hz, but the motor of frequency conversion water pump is usually three-phase. The incoming line is a single-phase 220V variable frequency water pump. The motor is a three-phase 220V motor, the input line is three-phase 380V, and the pump motor is three-phase 380V.Two, the differenceAccording to the definition above, the difference between variable frequency water pump and ordinary water pump is obvious. The main differences: first, the frequency pump has automatic function and constant pressure; ordinary water pump does not; second, variable frequency water pump is a unit, the price is much more expensive than the ordinary water pump.
Q:The diving pump in the aquarium stops and stops on the goldfish
Submersible pump is used as if you push the pump filtration should be open for 24 hours, so the water circulation process, continuously into the fresh air to increase the oxygen content of water bodies two, filter on the filter of the continuous cleaning system to maintain water make nitrification safe and clean, the water can be fully introduced the content of nitrification ammonia water, let the fish live healthy and strong resistance, good activity, three appropriate water flow on the long time to keep fish, turn off and the formation of water to fish is always in a state of tension and decreased immunity antifeedant or death. Four, frequently start the pump, easy to cause damage to the motor coil, reduce pump life, so according to the above, if you are using submersible pump as a filter to promote, I suggest you open 24 hours.
