The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspension emulsion, and liquid metal. Gear oil pumps can also transport liquids and gas mixtures, liquids containing suspended solids.
Absolute pressure refers to the pressure directly acting on the surface of the container or object, that is, the actual pressure that the object bears. Its zero point is absolute vacuum.
The pressure unit is Pa (Pascal), and the pressure of 1Pa is the force of 1N (Newton) acting on an area of 1m2. The leakage rate unit is Pa·m3/s. The conversion is shown in the table.
If user don’t understand the principle of vacuum pump oil, user might use oil indiscriminately, hence it will reduce the performance of the pump, and cause malfunctions.
Improper annealing and/or other unsuitable processing, improper shaft machining, insufficient design margins to withstand torque, fatigue, and corrosion etc.
