Pump industry suppliers - Basic principle and characteristics of double screw pump

based principle of screw water pump, screw pump is the use of the rotation of the screw to suction line of the liquid. Screw pump work, the liquid after inhaled into the external thread and surrounded by the pump body sealing interior space, when positive screw rotation, screw pump sealing capacity under the extrusion of the teeth to enhance working pressure of screw pump, and along the radial move, because the screw is constant speed rotation, so the liquid out of the traffic flow is symmetrical.

the kinds of double screw pump twin screw 杄 pump has not empty closed and sealed type two kinds, according to the material from side or both sides into the tooth and interior space, twin screw 杄 was divided into double suction type and single suction type two kinds of twin screw 杄 knot of the outer tooth screw 杄 pump, it USES tooth close to each other, touch each other the two screw 杄 to set of liquid, at one end and file a positive screw pump outside 杄 by gear drive.

double screw pump as - Within the capacity of pump, water pump inlet chamber should be sealed with row out room in space, therefore, pump body and screw 杄 external circular surface and screw 杄 and screw 杄 gap should be small as far as possible. Double screw pump can be divided into embedded rolling bearing and external rolling bearing two kind of way, embedded structure forms of rolling bearings of rolling bearings by John RunHua send content.

external bearing structure of the twin screw 杄 pump working lumen with rolling bearings are separated, because the structure of this kind of pump and screw 杄 side gap between entities, it is able to transport the wettability of the material.

in addition, adjust the synchronous gear screw pump does not meet the corrosion, the other half of the output torque is to send to driven screw 杄. Like all screw 杄 pump, twin screw 杄 external bearing type pump is also naturally aspirated work ability, and most of the component itself is full of double suction pump transportation symmetry layout, to eliminate the radial force, is also a lot of high absorption.

the characteristics of double screw pump advantage

1, double screw pump conveying liquid stability, no pulse, no mixing, little vibration, low with the sound.

2, has the strong naturally aspirated feature, polyphase melts when lose, choose RunHua alone, can transport a variety of nonwetting substances.

4, choose synchronous gear drive, the motor rotor middle don't touch, even if high speed can also be in such a short time.

5, double screw pump water pump body contain a heating jacket, can transport a variety of part clean or high viscosity with small solid particles or low viscosity material, proper use of raw materials, and can carry a lot of corrosion of the material.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern self-priming pump performance testing means, equipment is excellent. Main production ZA, ZAO, ZE petrochemical pump, CZ chemical process pump, IH chemical pump, forced circulation pump, SPP chemical mixed-flow pump 28 species such as qualitative, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts.

pool cover drain pump submersible pump is generally used to winter cover pump.
You can always ask the experts for the most appropriate pool cover drain pump submersible pump for your specific needs. Find the best support, prices and other to submersible pump solutions at J&T INDUSTRY.
As the full potential of winter cover pump lies in , the demand for is increasing globally, and is being adopted across the global market.
Further dialogue of JT between the approaches, the chapter concludes, could lead to actionable advice on more robust policies that drive both structural change and competitiveness upgrading.
