H -- stands for slide valve vacuum pump (the first letter of Chinese pinyin "HUA").
150 -- represents the geometric pumping speed of 150 l/s.
G - stands for new improved type.
A -- denotes the external displacement of the bearing.
B -- indicates that the guide rail structure is changed.
Suitable for vacuum smelting, vacuum drying, vacuum coating, vacuum impregnation and other vacuum operations. It can be used alone or as a front stage pump of other vacuum pumps, but it is not suitable for pumping from one container to another. When removing gases containing too much oxygen, explosive, corrosive to ferrous metals, chemical reaction to vacuum oil, water, dust, etc., an attached device shall be added.
Piston vacuum pump series is suitable for suction air and other general gas, when the use of gas ballast, pump suction can contain a small amount
A condensable gas, such as water vapor. When the suction contains too much oxygen, explosive, corrosive to ferrous metals, right
When the vacuum oil reacts with the gas, an additional device should be added. This type of pump can be used alone, also can be used as diffusion pump, roots pump
The front stage of the contour vacuum pump.
H series piston vacuum pump is a vacuum equipment which can remove general gas or contain a small amount of condensable gas (gas ballast device should be used). It is suitable for vacuum smelting, vacuum drying, vacuum impregnation, high-altitude simulation experiment and other vacuum operations. It can be used alone or as a front stage pump for other high vacuum pumps.
After the optimized design of counterweight, less vibration, low noise.
The bearing seal chamber is supplied with oil separately, which is separated from the 2H piston vacuum pump chamber to avoid premature damage of bearing and seal caused by impurities entering the bearing chamber.
According to the requirements of users, auxiliary oil tank can be attached to achieve the effect of cooling vacuum oil separation impurities.
Except for the old h-150, the motor is placed above the pump, compact structure, small area.
2H piston vacuum pump applications
2H piston vacuum pump relatively durable, long service life. The pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation and aviation simulation tests.
