Oil-free vacuum pumps are a new type of vacuum pump products that have been used more and more in recent years. The R series oil-free vacuum pump has the remarkable feature that it does not need to use any auxiliary medium, and only needs to rely on the reciprocating motion of its own mechanical components to achieve the corresponding vacuum degree. Compared with the traditional circulating water pump and rotary vane oil seal vacuum pump, the main features are as follows:
1. Compact body and light weight: Since the oil-free vacuum pump does not require other media to work, it saves the need to store additional working medium such as oil storage tanks and water tanks. (The traditional water circulation pump and oil pump are not large in size because they are powerful. The suction effect is better, but the machine itself has a water tank and a storage tank. Its outer dimensions can be made smaller. For example, the R300 oil-free vacuum pump has a size of 272×121×164cm, and an A4. The size of the paper is 210mm × 297mm, so the surface area of ​​any R300 is smaller than one A4 paper. The compact size is also only 4.1KG, which is lighter. The compact size and extremely light overall weight make the oil-free vacuum pump take up less space on the countertop, making it suitable as a matching air source for large equipment; it is easy to move, even for carrying out.
2. Lower noise: The oil-free vacuum pump can install the silencer at the air outlet end due to its structure, which can greatly reduce the wind noise of the gas and the metal parts of the pump, and the noise value is generally low. In general, the oil pump and the water pump need other working medium assistance. For example, if the oil pump is installed with a muffler, the pump oil may block it and cause the equipment to malfunction and cannot be used normally. For example, the St. Stephen R610 oil-free vacuum pump can achieve a vacuum of 0.097 MPa, completely exceeding the circulating water pump, but due to the installation of the silencer, the noise value is controlled below 50 decibels, which is quieter.
3. No need for other auxiliary working media, eliminating the need for maintenance: As mentioned at the beginning of this article, oil-free vacuum pumps can rely on the operation of their own mechanical components to pump gas, so there is no need to use water or pump oil to participate in the work. The main advantage is that it saves the purchase cost of pump oil, eliminates the trouble of replacing pump oil or water, and does not pollute the environment more environmentally friendly. Especially in some industrial or laboratory equipment, non-polluting and maintenance-free features make oil-free vacuum pumps more advantageous, such as R400 and R410, which are commonly used for vacuum adsorption, homogenizers, and spin coating machines for electronic components. and many more.
