Product Description
BY2GE type high-pressure pump |
(fuel high-pressure delivery pump, oil high-pressure delivery twin screw pump)
Structural features and uses:
a. This product is a double-suction structure of a twin-screw pump, and the helical surface
adopts a special high-sealing curve with independent intellectual property rights;
b. The pump of this structure is installed horizontally, positioned by bearings, the two screws
do not contact each other in the bushing, and the transmission of the two screws is
completed by the synchronous gear;
c. The pump of this structure can realize long-distance transportation of various media.
Flow: 2~200 m3/h
Inlet pressure: allowable maximum negative pressure -0.08 MPa
Outlet pressure: ≤ 8.0 MPa
Medium temperature: -20~220 ºC
Medium viscosity: ≤ 2000000 mm2/s (2 million cSt)
Speed: 100~1500 r/min
The direction of the inlet and outlet of the pump is determined by the user. If there are no
special requirements, our company recommends side in, up and out or side in and side out
from the direction of the motor.
Product introduction of twin screw pumpWe know that twin-screw pumps are structurally divided into single-suction twin-screw pumps and double-suction twin-screw pumps. The two major products of our company have their own characteristics and are introduced as follows: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.Oilfield: Crude oil transportation, oil and gas mixed transportation, polymer transportation, used as a multiphase pump.Petroleum: heavy oil, crude oil, asphalt, fuel oil, grease, lubricating oil, petroleum additives, gasoline, kerosene, diesel oil, various resins, etc.Coalition: coal tar and coal tar transportation. The twin-screw pump is also the most ideal pump for conveying coal-water slurry and has a longer service life than the single-screw pump.Chemical fiber: viscose, polyester, etc. High-viscosity PVA, aramid fiber, spandex, and other raw solutions have high efficiency.Chemical industry: glycerin, sorbitol, cosmetics, shampoo, facial cleanser, toothpaste, soap, washing powder slurry, titanium dioxide, ink, paint, latex paint, white glue, various high-viscosity materials, polymers.Food: chocolate, milk, dairy products, fruit juice, jam, pasta sauce, syrup, honey, beverages, condiments, vegetable oil, soybean protein, xanthan gum, starch, yeast liquid.Pharmaceuticals: syrups, health products, pharmaceuticals.Papermaking: pulp, adhesives, auxiliaries, etc.Shipbuilding: lubricating oil pump, fuel oil transfer pump, cargo oil pump.Oil depot terminal: unloading oil pump, loading pump, unloading pump, loading pump.Thermal power plant: heavy oil transfer pump, heavy oil fuel oil pump.Hydropower plant: lubricating oil pump.Gas filling station: LPG tanker loading and unloading, tank dumping, etc.Metallurgy: lubrication pump, oil supply pump, fuel injection pump, water-glycol, and other delivery pumps.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
