PRINCIPLE:-
VIP Dosing/metering pump is precise volumetric control metering
pump for feeding, measurement and control system. It is positive return type
plunger.Diaphragm pump where flow can be adjusted from 0 to 100% while the pump
is running or at rest by stroke changing mechanism. Reciprocating motion to
achieve desired fluid control by stroke setting micrometric manual adjustment or
pneumatic or elecrical actuators.
THE DESIGN:-
VIP unique design for
accurate dosing the plunger stroke length must be adjustable with almost
precision from ZERO to 100% of maximum of stroke length in power end mechanism
most important design for accuracy is connecting ball joint with piston and eccentric disc. variations in the discharge capacity are by micro-mereic
adjustment or pneumatic or electrical.
ZERO
STROCK
High rotary motion is
transmitted by craft make high speed worm to wheel in a perpendicular plane, the
crank disc also revolves in the perpendicular plane which eliminates
reciprocating action in the cross head and plunger rendering the pump to a zero
stroke.
FULL OR PARTIAL STROKE
For 100% or
at any internal stroke setting worm gear is adjusted away from the perpendicular
plane i.e. the eccntric disc move back off the perpendicular axis. As the
connecting ball joint transmits a reciprocating motion to the crosshead and
plunger. In such position the pump is at 100% or at partial stroke setting as
the case may be stroke length adjustment by changing the radius of the
reciprocating crank eneuides near harmonic motion for the plunger travel at all
stroke length the ball checks on suction and discharge are synchronized to
respond resulting in to efficient operation of the pump.
VALVES:-
Metering pump check valves
are heart of the pump performance, Precision and accuracy depend on the correct
shape and design to suit for known Fluid characteristics.
In
addition to above , VIP has special designs of value
like:
1. Slurry valves
2. High Viscocity valves
3. Soft seal valves
4. Special Metal Valves
5. Inverted Design
Valves.
