5. Installation
1. Before installation, checking each parts and make sure there have no damaged, and to see
whether the product is fit to order contract.
2. The pump must be installed in a place of cleaning, no dust or a little dust and infection with
dielectrics. According to its operating condition, the pump’s inlet port can be equipped an anti-
dust device (such as an oil-sealed mechanical pump used as pump).
3. The pump’s operating environment temp. is 5-40 ℃ and the max. Temperature rise is cannot
exceed 100 ℃.
4. According to operating condition, the pump can be installed to a cement base or steel frame
base which should be calibrated. Otherwise, it will be seriously affect the pump’s normal
operation.
5. The gas inlet pipe should be kept sealing, even a small leakage will affect its vacuum.
6. The length of a pipe is as short as possible, using less joint and elbow with its diameter less than
its pump’s bore.
7. A flexible soft pipe such as a metal bellows should be linked between this pump and a fore
pump so as to prevent damaging this pump because of fore pump’s vibration.
8. It is better to equipped a vacuum valve on the pump’s inlet and outlet pipes so as to keep the
vacuum of pump cavity after stopping operation.
9. A valve should be installed on inlet pipe for cooling water so as to regulate water quantity and
control the outlet temperature of cooled water at 20-40℃。 Pay attention to the water
temperature not over 40℃ so as to avoid producing sediment in a water tank.
10. An advance vacuum pump must be used as this pump’s fore pump which is not used alone. If
an oil-sealed mechanical vacuum pump is used as its pump, the two may be used in series
connection. So this pump is not suitable for drawing out the gases such as too much oxygen
content, explosiveness, corrosion to ferrous metal, chemical reaction to vacuum oil and containing
dust etc. Otherwise, the service life of a fore pump will be shortening.
