Product Description

Basic Information

The H-150 slide valve vacuum pump is a type of oil-sealed rotary variable volume mechanical vacuum pump. The "H" represents "slide valve vacuum pump", which is the first letter of "HUA" in Chinese pinyin, and "150" indicates the geometric pumping speed of 150 L/s.
 

 

Structural Features
- Horizontal Structure: The connection between the guide hole of the H-150 piston vacuum pump and the center of the pump cavity is at a 30° angle to the horizontal. There are two types of motors, side-mounted and overhead-mounted. The overhead-mounted type takes up less floor space.
- Exhaust Port Design: The oil tank is equipped with a side cover, and the exhaust port is set on it. This design enhances the ability to prevent oil injection at high inlet pressures, reducing oil consumption and environmental pollution.
- Oil Way System: Oil enters the oil pump from the oil tank through an oil filter, then into the oil box, and is distributed to both ends of the pump chamber. The oil from friction parts such as between the piston and the guide rail and the eccentric wheel flows back to the oil tank through the exhaust valve.
 
Working Principle
The motor drives the shaft to rotate, and the eccentric wheel drives the slide valve to move. The slide valve divides the pump cylinder into an intake chamber and an exhaust chamber. As the slide valve moves, the volume of the intake chamber increases, sucking in gas from the inlet. Then, the intake chamber is converted into an exhaust chamber, and as the volume of the exhaust chamber decreases, the gas is compressed and discharged through the exhaust valve after passing through the oil-gas separator.

Performance Advantages
- High Vacuum Degree: The H series can reach a vacuum degree of 1 Pa.
- Low Vibration and Noise: The bearing seal chamber is separately supplied with oil, which is separated from the pump chamber, preventing impurities from entering the bearing and causing premature seal damage.
- Wide Applicability: It is suitable for pumping air and other general gases. When using air ballast, it can also pump a small amount of condensable gases like water vapor.
 
The H-150 sliding vane vacuum pump has a wide range of applications, and the following are some of the main fields:
- Vacuum Smelting: It is used in smelting methods such as vacuum melting, vacuum sintering, and vacuum degassing. It can greatly reduce the gases and impurities in metals and alloys, obtain high-purity materials, improve the compactness, uniformity, and reliability of the materials, and eliminate defects such as white spots, segregation, and cracks in steel ingots. For example, in the smelting of magnesium powder, a Roots pump + sliding vane pump unit can be used to maintain the vacuum degree and remove a large amount of generated gases.
- Vacuum Drying: In the vacuum drying process of foods, pharmaceuticals, chemical raw materials, etc., the H-150 sliding vane vacuum pump can quickly extract moisture and other condensable gases, allowing the materials to be dried at a low temperature, reducing the impact on the quality of the materials. Moreover, the drying speed is fast and the efficiency is high, which can effectively maintain the nutritional components, color, and shape of the materials.
- Vacuum Coating: In vacuum coating processes such as optical coating, decorative coating, and semiconductor coating, it is necessary to evacuate the vacuum chamber to a certain degree of vacuum before coating. The H-150 sliding vane vacuum pump can quickly extract the air and other gases in the vacuum chamber, providing a clean and stable vacuum environment for coating, ensuring the quality and performance of the coating.
- Vacuum Impregnation: In the production of transformers, wires and cables, and capacitors in the power industry, vacuum impregnation treatment is often required. Insulating paints and other impregnating agents are filled into the gaps of components such as windings in a vacuum state to improve the insulation performance and moisture resistance. The H-150 sliding vane vacuum pump can help meet the air extraction requirements during the vacuum impregnation process.
- Chemical and Pharmaceutical Industries: In chemical synthesis, distillation, extraction, and other processes in the chemical industry, as well as in the drying, concentration, crystallization, and other processes of pharmaceuticals in the pharmaceutical industry, it is often necessary to create a vacuum environment. The H-150 sliding vane vacuum pump can be used to extract gases and condensable vapors from equipment such as reaction kettles and distillation columns, control the reaction conditions, and improve the product quality and yield.
- Aerospace: In high-altitude simulation tests, space environment simulation, and other tests in the aerospace field, it is necessary to simulate the vacuum environment of space. The H-150 sliding vane vacuum pump can serve as an important part of the vacuum system, providing the required degree of vacuum for the test equipment and ensuring the accuracy and reliability of the tests.
