Bonve rotary Lobe Pumps for lube oils
Lube oils are liquid or semi-solid
lubricants used in various types of automobiles and machinery to reduce
friction and protect machines and machined parts. Mainly used for lubrication,
cooling, rust prevention, cleaning, sealing and cushioning.
The problem
Screw pump and gear pump are normal to
see for lube oil transferring. But usually users will face below problems
|
Screw pumps
|
|
Heavy damage might be
caused due to dry run
|
|
Sensitive to the change
of viscosity
|
|
The fluid may leak out of
the pump body and cause pollution to the environment and the pump body.
|
|
Maintenance is
inconvenient
|
|
Gear pump
|
|
The inter-tooth groove of
the end cap and gear constitutes a number of fixed sealing working chambers,
which can only be used as a dosing pump
|
|
Unbalanced radial force,
large flow artery, high noise
|
|
Low efficiency, poor
interchangeability of parts, difficult to repair after wear
|
|
High cost of wearing part
to replace
|
The solution
With the characteristics of low rotation
speed and high output torque, Bonve rotary lobe pump shows his talents to
transfer high viscosity lub oils. Its unique working principle works with a
strong drive system, ensure that the pump can output a strong driving torque at
low speed, can guarantee continuous, non-stagnant transferring.
Advantages of Bonve Lobe Pumps
-
Gap is kept between the
rotors to allow no friction, thus to ensure long service life.
-
Simple installation and
disassembling easy maintenance and cleaning, strong resistance to wearing.
-
High efficiency and energy-
saving, stable transmission, low failure rate, good sealing and low noise.
-
A heat retaining device can
be built in structure.
-
Suitable temperature: 1~250c
degree.
How Bonve Lobe pump works?
The even rotation of the rotor pair creates a vacuum on the
priming side of the pump, which can be defined by the direction of rotation of
the drive. This vacuum draws the liquid into the pump chamber. With further
rotation, the pumped medium is conveyed past the pump wall into the pressure
area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a
standstill, the pump seals off almost
completely.
