1. Product Overview

The 2GB high vacuum discharge pump is an improved and upgraded version of the vacuum discharge gear pump. Adopting a modular design, the product has stronger universality and is easy to assemble and maintain. According to the on-site usage, the import and export form adopts a horizontal suction and vertical discharge form. Facilitating on-site installation. The import and export flanges adopt standard flanges from the Ministry of Chemical Industry, which facilitates customer matching.

With the promotion of the application of vacuum discharge gear pumps, some operating conditions are constantly changing. In the vacuum distillation process, the vacuum degree of the pressure reducing kettle is getting higher and approaching the ultimate vacuum state, which poses a great challenge to the vacuum suction performance of the vacuum discharge gear pump. The vacuum suction performance of the vacuum discharge gear pump is far from meeting the requirements for use. The 2GB high vacuum discharge pump is designed to meet the requirements under extreme vacuum conditions. The vacuum extraction ability of the pump is stronger, and under the extreme vacuum conditions of absolute vacuum pressure, the vacuum extraction ability of the pump is also very strong.

The 2GB high vacuum discharge pump is a gear pump designed for vacuum distillation equipment; In industries such as fine chemicals, biologics, and grain and oil processing, short-range distillation gear pumps are necessary in the short-range distillation process; In the waste oil regeneration industry, it is a waste oil distillation gear pump that is used to distill and vacuum oil for waste oil regeneration equipment.

Especially in the waste oil regeneration industry (including the regeneration of waste oil such as waste engine oil, waste diesel, waste kerosene, etc.), the successful development of the 2GB high vacuum discharge pump has revolutionized the production process of the waste oil regeneration industry. As a result, the quality of oil products regenerated from waste oil has been significantly improved, and the production efficiency of waste oil regeneration has seen a leap forward. The investment scale and production cost of waste oil regeneration have been greatly reduced. At the same time, it also solves the bottleneck problem of no pump option for the vacuum distillation oil pump that has always existed in the waste oil regeneration process. Therefore, the 2GB high vacuum discharge pump is an excellent gear pump for waste oil regeneration and distillation.

In addition, the application effect of 2GB high vacuum discharge pump on high vacuum oil filters is also very good. Especially in the successful application of transformer oil high vacuum oil filters, it completely solves the long-standing problem in the oil filter industry that the use of gear pumps on transformer oil high vacuum oil filters can cause acetylene gas to be produced in the filtered transformer oil, thereby reducing the insulation index of transformer oil. The 2GB high vacuum discharge pump is used in conjunction with the large transformer of Baoding Transformer Group of China Railway Bureau. The insulation index of the transformer oil filtered by the transformer fully meets the standards, and there is no production of acetylene gas. It completely replaces imported pump products such as Viking pump from the United States, Maag pump from Switzerland, and Witt gear pump from Germany.

Due to the limitations of centrifugal pumps in principle, they are powerless to pump materials under high vacuum pressure. The vacuum extraction capacity of positive displacement pumps (including gear pumps, screw pumps, plunger pumps, diaphragm pumps, cam rotor pumps, etc.) is also very limited. Therefore, the 2GB high vacuum discharge pump is the best choice for vacuum discharge pumps in molecular distillation, vacuum distillation, and short-range distillation processes.

II Structural characteristics

Compared with other vacuum discharge gear pumps, the 2GB high vacuum discharge pump has optimized the design of the turbocharger, which has a stronger turbocharging effect and stronger vacuum extraction ability. Under the extreme vacuum conditions of absolute vacuum pressure, the vacuum extraction ability of the pump is also very strong.

The 2GB high vacuum discharge pump has a sophisticated design, unique structure, and excellent vacuum discharge effect.

The 2GB high vacuum discharge pump is a two-stage pump that combines turbocharging and positive displacement pump. Its main structure is a gear pump, and the gear design adopts internationally advanced circular arc gears, which operate smoothly, have low vibration, low noise, long service life, and strong self-priming performance of the pump. The turbocharger pump designed in the first stage changes the suction pressure state of the second stage gear pump, thereby changing the negative pressure suction of the second stage gear pump to positive pressure suction. The pump can pump materials normally even in absolute vacuum state during operation.

The 2GB high vacuum discharge pump is generally used in short-range distillation, vacuum distillation, and molecular distillation processes. The high temperature and high vacuum inside the distillation tower require very strict reliability of the seal. The sealing forms of pumps are divided into the following types:

1) Rubber mechanical seal, with a maximum operating temperature of 200 ° C;

2) Metal bellows sealing, with a maximum operating temperature of 300 ° C;

The magnetic transmission structure is a leak free structural form, using high-temperature resistant rare earth permanent magnet materials, with a maximum operating temperature of 300 ° C.

3) The magnetic transmission structure is a leak free structural form, using high-temperature resistant rare earth permanent magnet materials, with a maximum operating temperature of 300 ° C.

III Application scope

The 2GB high vacuum discharge pump is widely used in industries such as petroleum, fine chemical, daily chemical, biologics, biopharmaceuticals, grain and oil, and pharmaceuticals.
