Laboratory oil-free vacuum pump features
The laboratory oil-free vacuum pump is designed for all kinds of vacuum equipment in the laboratory. Can be used for vacuum concentration, vacuum filtration, vacuum drying and other occasions. Has the following characteristics:
1. Provide sufficient motor power to reduce motor heating.
2. The vacuum film is made of high-quality rubber with good oil resistance and fatigue resistance, and is provided with a reinforced textile skeleton interlayer with a thickness of 3 mm and a greatly improved service life.
3. The pressure of the double-stage pump head can be close to 0.1Mpa, and the large-flow structure can also be used.
4. High efficiency, low noise, optional pressure regulation and exhaust valve configuration.
The laboratory oil-free vacuum pump is an important filtering equipment for improving filtration efficiency and enhancing degassing effect. In order to ensure that the filter media is not contaminated, an oil-free diaphragm vacuum pump is generally used. The vacuum pressure of this type of pump is generally around 0.08 Mpa (single stage). The key to increasing the filtration speed is the displacement per unit time, that is, the flow rate of the vacuum pump, which is particularly prominent when the filter is large and the viscosity of the medium is high.
The service life of the laboratory oil-free vacuum pump depends on the correct method of use (such as reducing the artificial continuous start-up, preventing the solvent from being pumped into the pump body, etc.), mainly in the reasonable power of the motor and the design form and fatigue resistance of the vacuum membrane. .
