The Characteristics And Application Of Single - Suction Twin Screw Pump

- May 22, 2018-

The characteristics of

The cleaning is quick and convenient.

It can transport liquids smoothly and without shear.

It has a strong self-priming capability and can mix and lose steam.

There is no contact between the working elements, and a certain amount of fine particles (such as kaolin, etc.) can be carried.

Temporary dry operation (less than 2min)

The viscosity of the material can reach 100000mm2/s.

It changes the speed to adjust the flow, and the output pressure remains stable.

It has synchronous gears and bearing external.

All kinds of driving modes can be used.

Different import and export connection modes can be selected (flange or circular thread connection)

It is convenient to disassemble and assemble, and the maintenance is simple.

Efficient energy saving

Range of application

This series of pumps can be used in the following industries.

Chemical industry: all kinds of acid, alkali, salt liquid, resin, glycerin, paraffin, heavy residue oil, gasoline and other chemical raw materials.

Paint industry: ink, various paints, pigments, coatings, etc.

Beverage industry: alcohol, alcohol, honey, syrup, toothpaste, milk, cream, soy sauce, vegetable oil, animal oil, chocolate, Babel, etc.

Pharmaceutical: various preparations, glucose, and various injection.

Working principle and structure characteristics.

In the working process of the pump, screw and screw and screw and bushing formed between sealed cavity, liquid after imported into the pump, and then into the sealed cavity, with the rotary motion of the screw, a steady inlet to the exit.

No agitation, no pulsation, low noise.

This is determined by the working principle of the screw pump. No matter the time or place, it has no effect on the surrounding environment. The intrinsic working principle of the screw pump ensures that the pressure pulsation is almost zero when working. Ultra-low noise design and carefully selected other supporting rotating parts ensure that the entire unit does not have any impact on the residents near the gas station even at night.

Good working ability.

Relative position by the seam allowance of lining hole position, by the screw shaft bearing positioning, and work to keep the screw and screw and screw and bushing between each other contact, therefore, allowed to dry pump running, It is suitable for conveying various media (such as Newtonian and non-newtonian fluids, lubricants and non-lubricated liquids, corrosive liquids, etc.).

L is suitable for frequently started working conditions.

It can be started up to 15 to 20 times per hour.

L has high absorption ability and strong self-absorption ability.

Because of the special design of imported runner and the relatively small axial velocity of liquid at work, the NPSHr value of the pump is very small and has good suction capacity. The bearing and the synchronous gear are lubricated by gear oil in the gearbox, and the outlet is located at the top of the pump. When the pump is stopped, the pump has enough media to be retained, so the pump has a good self-priming capability. The maximum suction vacuum can reach 8.5m water column. The W.kse double screw pump adopts a special combination of screw thread and special pump chamber design to ensure the pump can maintain high efficiency during the working period.

L simple operation, easy maintenance.

Warren kozirenski se type twin-screw pump adopts unique design method, the operation and maintenance is very convenient, can easily remove the screw pump body connection, unload the pump body separately, thereby directly cleaning pump body, screw sleeve and mechanical seal, pump parts without blind Angle. Available of the steam temperature is below 180 ℃ or other media for cleaning or sanitizing pump. The repair and replacement of the seal does not affect the other parts of the unit, the pump work is extremely reliable and safe.

Pump outlet can put safety facilities (such as relief valve, pressure control valve, relief valve, etc.), if need be, pump unit can provide for the mobile (base is equipped with four small wheels and traction arm).

Simple maintenance, satisfactory working life.

Warren kozirenski se type pump adopts special structure design, bearing axial force, between the screw rotor, no metal contact between the rotor and the pump shell, so as to ensure the pump work long time almost no wear and tear. The clever transmission structure design makes the daily maintenance work almost zero. Long service life of pump.

L special design, adjustable speed.

According to the requirements of the user, the motor drive pump can be driven by stepless speed regulating motor or the motor driven pump with variable frequency speed control system. The common feature of these motors is to adjust the speed of the motor to adjust the flow rate of the pump.

Structure that

The maximum pressure the pump can withstand is 1.6MPa. Pump inlet and outlet connection: connection of flange connection and pipe thread. The pump body has a discharge hole, so there is no need to worry about the liquid stored in the pump. The gearbox is filled with oil holes, drain holes and vent plugs.

Seal form

The standard rotation direction of the pump is clockwise (from the end of the shaft), and the installation of mechanical seal is independent of the steering.

The sealing form is divided into:

1) standard mechanical seal form (M1) using temperature 20 ℃ ~ 180 ℃

(2) with cooling device of mechanical seal form (M4) using temperature - 20 ℃ ~ 180 ℃

A cooling connector with a shaft seal and a g1/4 ".

(3) rubber oil seal form (M3) use temperature - 20 ℃ ~ 180 ℃

A cooling connector with two shaft seals and one g1/8.
