What is an oil-free gas pump?
The oil-free air pump means that there is no lubrication between the piston and the cylinder of the air pump, and the piston ring and support ring are made of graphite containing material.
Oil-free air pump is the piston between the pump and the cylinder without lubrication, the piston ring is a special material, usually used to pump clean special gases, such as liquefied gas, gas and so on.The oil-free air pump has two functions of air suction and blow drying. The gas passed through it has no oil and is dry. It has the characteristics of large pressure, large air flow, easy installation, low noise and high efficiency. Working principle: no oil pump during rotation of the impeller, the impeller of the gas by rotating movement along the blade and the radial direction is accelerated, the base after the gas enters the outer ring gas by pressure difference effect and return to the blade and the formation of strong airflow, so the cycle gas in the gas ring in the spiral direction of movement the pressurizing purpose. After the gas moves to the exhaust port, because the pressure is greater than the system pressure, the gas is discharged rapidly, and the use of the oil-free air pump, air suction and air supply, the use of a wide range.
The so-called oil-free pump refers to the air pump piston and cylinder between the absence of lubricating oil, piston ring is a special material, usually used to pump clean special gases, such as liquefied gas, gas and so on.
