Oil-free vacuum pump series piston vacuum pump is a negative pressure vacuum pump that can operate without any oil lubrication. It has the advantages of simple structure, easy operation, convenient maintenance, and no environmental pollution. Shengyuan series oil-free vacuum pump has good durability. It is a vacuum pump for vacuuming, compression and dual-purpose. It is a basic equipment for obtaining vacuum with a wide range of applications.
Oil-free piston vacuum pump is a small vacuum pump for vacuuming. Basic equipment used to extract gas from sealed containers to obtain a vacuum. Compared with the oil pump, the oil-free vacuum pump has a low degree of vacuum and a small amount of air, but it is small in size, easy to install, simple to maintain, easy to move, does not generate oil fume, and does not pollute the environment, especially in laboratories with higher requirements. One of the equipment in the room.
This pump is not suitable for pumping out gases that are corrosive to ferrous metals, chemically react to pump oil, contain particulate dust, and are explosive and toxic gases with high oxygen content. Not even as a transfer pump (i.e. pumping from one container to another). This pump can be used for air conditioning, repair of refrigeration equipment, suction devices for medical equipment, printing machinery, vacuum packaging, vacuum blister, physical and chemical experiments and small devices that require a vacuum environment. It can also be used as a backing pump for small oil booster pumps, oil diffusion pumps, molecular pumps, etc. The working principle of oil-free vacuum pump is the same as that of general positive displacement pump, which is composed of connecting rod, piston ring, cylinder block, motor and other main parts. The connecting rod with the piston ring is installed in the fixed cylinder. When a stroke is completed, the four radial sliding pistons in the cylinder groove divide the pump chamber into four working chambers. Due to the centrifugal force, the pistons are close to the cylinder wall. The inlet and outlet of the stator are separated, the cycle is repeated, the volume is changed, and the inhaled gas is discharged from the exhaust port, so as to achieve the purpose of vacuuming.
Optional piston oil-free vacuum pump
When purchasing an oil-free vacuum pump, you must first determine the vacuum degree required to work. If the required degree of authenticity is high, the selected vacuum pump must be higher than the required vacuum degree. Otherwise, the vacuum pumping requirements will not be met. Work requirements. The second is the pumping rate of the oil-free vacuum pump, which should be slightly larger than the required pumping rate during model selection, so that it can better meet the needs. After Z, check whether the extracted gas is corrosive or not. Corrosive gas will corrode the pump, and special materials must be used to meet the needs.
