Oil free vacuum pump is a kind of mechanical vacuum pump which can operate without any oil. The utility model has the advantages of simple structure, easy operation, convenient maintenance and no environmental pollution. The two series of oil-free vacuum pumps have good durability. They are vacuum pump, compression pump and dual-purpose vacuum pump. They are a basic equipment with a wide range of applications to obtain vacuum.
Laboratory small oil-free vacuum pump working principle :
The working principle of oil-free vacuum pump is the same as that of general positive displacement pump, which is composed of main parts such as stator, rotor, vane, cylinder block, motor, etc. The rotor with rotor blades is installed in the fixed cylinder eccentrically. When the rotor rotates at a high speed, four radial sliding rotors in the rotor slot divide the pump cavity into four working rooms. Due to the centrifugal force, the rotor blades cling to the cylinder wall, separate the inlet and outlet of the stator, and start the operation again and again, change the volume, exhaust the gas from the exhaust port, so as to achieve the purpose of air extraction, instead of Rotary vane vacuum pump needs vacuum oil to use.
Principle of oil – free vacuum pump: Oil – free design, reciprocating operation of piston, no need to maintain completely, save trouble and worry
Oil free vacuum pump technology: advanced technology, precision construction, very low noise (less than 50 dB), avoid noise interference
Oil free vacuum pump quality: through 3000 hours of continuous load test, reliable quality, two-year warranty, no worries
Oil free vacuum pump configuration: there is a vacuum degree regulating valve, which is convenient for the operator to manually adjust to the required vacuum pressure; there is a simple installation package available for purchase, and the user can easily and quickly convert the vacuum pump into a positive pressure pump
Application of oil-free vacuum pump: fast filtration and degassing of solvent with solvent filter bottle; suitable for filtration and degassing of mobile phase in liquid chromatography; widely used in weight analysis, microanalysis, colloid separation and sterility experiment
Note: the vacuum degree and flow rate can be adjusted by regulating valve (including vacuum gauge, filter and regulating valve)
