Product Description
BY2GS Ordinary Double Suction PumpApplication Examples:
Tank farm oil delivery, backfilling, loading pump, fuel transfer pump, fuel injection pump, etc. lShipbuilding: used as marine loading pump, scavenger pump, marine ballast pump, main engine lubricating oil pump, cargo oil pump, etc.
Also known as: sewage pump, loading pump, sweeping pump, marine ballast pump, fuel transfer pump, fuel injection pump, etc.The BY2GSZ pump is suitable for the delivery of various flowable liquids. The conveyed materials include all kinds of dirty oil and so on. BY2GSZ pump is suitable for applications with the large flow (generally more than 80 m3/h) or (and) high pressure (more than 3MPa). Structural features and uses:
1. This product is a double-suction structure of a twin-screw pump, and the spiral surface adopts an advanced Ω-shaped symmetrical form;
2. The pump of this structure is a double-suction horizontal installation. Through the bearing positioning, the two screws do not contact each other in the bushing, and a constant gap is maintained between the tooth sides (the gap value is determined by the working conditions and the specifications of the pump itself). There is also a constant gap between the circle and the inner surface of the bushing. The transmission of the two screws is completed by synchronous gears. In addition to transporting good lubricating media, this structure can also transport a large amount of non-lubricating media and media of various viscosities. Since the core working parts of the screw sleeve do not touch each other, there is no danger even if it runs dry for a short time (3~5min). Therefore, it is widely used.
3. The pump of this structure can realize forward and reverse operation (our company has It is a unique structure designed by our company, please request it in the contract if you need this function)Performance Range
It should be noted that the performance parameters corresponding to each series are different. When selecting models, please contact us anytime, our professional technician will provide you correspond information. Flow: 10~2000 m3/h (large flow can only be achieved at low viscosity)Inlet pressure: -0.05~0.8 MPaOutlet pressure: 0.1~4.0 MPaMedium temperature: -20~200 ºCMedium viscosity: 0.5~100000 mm2/sSpeed: 50~1500 r/minThe import and export direction of the pump is determined by the user. When there is no special requirement for the import and export direction of the pump, our company recommends the horizontal direction, which is left in and right out when viewed from the direction of the motor.After confirming the model, if you need more detailed drawings and installation dimensions, please contact us and our technical department will answer for it. Besides, if you have any requirements about the specifications of the inlet and outlet flanges of the pump, please also negotiate with us.performance data
If you need more detailed parameters, you can ask for it from our company at any time. The software independently developed by our company (BY2GS type ordinary double suction pump.exe) can display the relationship between pump specifications and flow, pressure, speed and viscosity.

The product feature of the single-suction twin-screw pump is that the pump unit has a pair of left and right rotating screw sleeves, which are divided into cantilever types (see Figure 1) and A-type lines (see Figure 2). The product has a simple structure and is easy to use and maintain. It is used for occasions where the flow is not large and the pressure is not high.
The product feature of the double-suction twin-screw pump is that there are two pairs of left and right-handed screw sleeves in the pump unit, as shown in Figure 3. The product structure is more complicated than the former, and the use and maintenance are more difficult than the former. It is mainly used for large flow or (and) pressure high occasions. The double-suction twin-screw pump has been carefully built by our company's R&D personnel for many years and has achieved effective measures such as quick replacement of seals and quick adjustment of helical surface clearance.
In recent years, the helical surface with independent intellectual property rights developed by our company is at the leading domestic level.2 the characteristics of twin screw pump1. In the structure, a certain gap is maintained between the screw and the screw, between the screw and the bushing, and there is no direct mechanical wear. Low noise and long life.
2. If the external structure is selected, the transmission system is independently lubricated, does not contact the conveyed medium, and can convey lubricating and non-lubricating media.
3. It can be designed as a heat preservation and sealed cooling system, which is suitable for medium transportation in high temperatures, corrosion, abrasion, and other occasions.
4. Compared with other pumps, the conveying viscosity range is wide. When conveying a high-viscosity medium, it has high efficiency and energy saving, low failure rate, and can convey extremely high-viscosity chemical materials; and when conveying a low-viscosity medium, it has outstanding advantages such as smooth conveying, no stirring, and no pulsation, and different materials are used. Natural materials can be mixed with gas and liquid, and liquefied gas.
5. It can realize flow regulation under constant pressure, suitable for frequency conversion control, and the effect of energy saving and consumption reduction is remarkable.
6. Disadvantages: The twin-screw pump requires high manufacturing precision, a complex manufacturing process, and many tooling, so the manufacturing cost is high and the selling price is high.3. Application fields of twin-screw pumpThe twin-screw pump uses a wide range of viscosity, and the conveyed medium is stable. The viscosity of the medium it transports is as low as liquefied gas transportation and as high as toothpaste-like medium transportation that is close to solid. Not only that, because the screw pump moves the medium in axial translation, it conveys the medium smoothly and without pulsation, which is suitable for conveying those easily vaporized liquids, high-viscosity materials, and media that require self-priming; during the conveying process, it double The screw pump also shows excellent energy saving effect.
The twin-screw pump, due to the non-contact of the screw profile, not only overcomes the defects of easy wear and aging of the rubber bushing of the single-screw pump but also overcomes the problems of contact between the profile and the bearing and the medium of the three-screw pump. Our company has also carried out a lot of technical research and development according to various working conditions, forming our company's unique twin-screw pump products, which are widely used in the market.

In short, the twin-screw pump can efficiently transport various high and low viscosity media, especially the media that do not allow stirring and the media that are easy to vaporize. The twin-screw pump can also convey the medium smoothly and without pulsation under the condition of high temperature and high pressure. The excellent characteristics of twin-screw pumps have become more and more recognized.
The twin-screw pump can completely replace the use of other products, such as replacing centrifugal pumps, sliding vane pumps, etc. for high-viscosity liquid transportation. We know that when the viscosity of the centrifugal pump exceeds 20cSt, the efficiency will drop sharply, and the screw pump even if the delivery When the liquid reaches 1 million cSt, still has high efficiency, especially with extremely high volumetric efficiency. Therefore, for the higher viscosity of the conveyed medium, the screw pump should be considered to achieve the purpose of saving energy and reducing consumption. Company Profile
