1. Introduction
1.1 Application range and definition
This manual contains installation, operation and maintenance instructions for the BAOSI
hydraulic coupling series roots vacuum pump. The user must use the pump as specified in
this manual and must read this manual before installing and operating the pump.
Important safety information is highlighted by WARNING. The use of WARNING is
defined as follows.
WARNING
Warnings are given where failure to observe the instruction could result in
injury or death to people.
The units used throughout this manual comply with SI International Measurement Unit.
1.2 Description
1.2.1 Outline
The pump is compact and has a high pumping speed. The user must use the pump with a
suitable backing pump. The pump can operate continuously at an inlet pressure of up to
1000mbar (causing the pump body temperature to be abnormally high). Using of two or
more pumps in series can get lower system pressures.
The motor side cover and the gear side cover of the pump are connected to the pump outlet
by a pressure equalization passageway to form a part of the vacuum system. The connecting
passageway is provided with felt to remove debris to prevent contamination of the
lubricating oil and bearings.
The BSJ600LC and BSJ1200LC pumps have a cooling pipeline in the pump outlet, to reduce
the temperature of the rotor and exhaust gas.
Normal operation within the parameters specified in this manual, the pump can safely pump
non-combustible gases and vapors.
The inlet flange and outlet flange of the pump are ISO standard flange.
1.2.2 Structure
The pump is a positive displacement roots vacuum pump, and the three-phase motor drives
the pump through a hydraulic drive.
The bearings, gears and seals of the pump are lubricated by the pump oil inside the motor
side cover and gear side cover. A series of oil seals stop the oil from reaching the rotor side
of the pump. Inside of the motor side cover and gear side cover is evacuated. You can check
the oil level by the oil level sight glass mounted on the motor side cover/gear side cover. The
motor side cover/gear side cover is equipped with a refilling screw plug and an oil drain
screw (see Fig.2).
1.2.3 Principle of operation
The motor shaft of the pump drives one of the rotors in the rotor housing through the
hydraulic drive inside the motor side cover. The synchronizing gears drive the second rotor
in the opposite direction inside the rotor housing. A small clearance is maintained between
the rotors and between the rotors and the inner wall of the rotor housing. This clearance
allows the pump to operate at high speed without mechanical wear and without the need for
lubrication inside the swept volume.
1.2.4 Hydraulic drive
The hydraulic drive consists of a fluid coupling which connects the motor shaft to the rotor.
The system configuration ensures that the rotor's rotational speed is reduced, when the gas
load is too high. When the gas load is reduced, the rotors accelerate to full speed. This allows
the pump to operate continuously over the vacuum range without the risk of motor overload
and without the need for bypass valves and associated pipelines.
The fluid coupling is extremely sensitive to the viscosity of the pump oil. The packaged
pump is equipped with special oil for the BAOSI vacuum pump.
