Tripple-Connection OilField Mud System Balance Elliptical Shale
Shaker
General Description:
Base on ZS/T-1C series elliptical shale shaker, we make XBSY Tripple-Connection type
Drilling-fluid shale shaker is applicable to solid control system of drilling fluid of
petroleum and natural gas exploration and it is the first stage
equipment for solid-liquid separation of drilling fluid.
ZS/T-1C series shale shaker includes type ZS/T-1C
translational-motion elliptical vibrating screen, type ZS/T2-1C
translational-motion elliptical 2-in-1 vibrating screen and type
ZS/T3-1C translational-motion elliptical 3-in-1 vibrating screen.
ZS/T-1C series elliptical shale shaker for solid phase separation of drilling fluid adopts 2 sets of
vibration motor to realize elliptical movement of screen box along
designed direction so as to screen out and discharge granular
drilling cuttings in drilling fluid.

IV. Structural composition and overall dimensions
ZS/T-1C series elliptical vibrating screen consists of 5 main
parts, i.e. base frame, screen box, mud box, dip angle adjusting
device and electrical control system.
Screen box is linked on base frame by rubber spring, thus forming a
typical “spring-mass” vibration system.
2-in-1 and 3-in-1 vibrating screen are formed by combining 2 sets
or 3 sets of vibrating screen together to share a common base frame
and a mud box for convenience of installation and transportation.
Overall dimensions of the equipment are shown in Fig.1, 2 and 3.
Explosive view of a single unit is shown in Fig.4. Explosive view
of screen box is shown in Fig.5 and explosive view of dip-angle
adjustment mechanism is shown in Fig.6 and 7. Explosive view of
splash-proof cover plate is shown in Fig.8. Explosive view of
2-in-1 and 3-in-1 vibrating screen is shown in Fig. 9 and 10,
respectively.
V. Operation principles
ZS/T-1C series elliptical vibrating screen is of a twin-shaft self-synchronizing inertia elliptical
vibrating screen with unequal mass-radius product. Two sets of
vibration motor with unequal mass-radius product are installed
horizontally and rotate in reverse direction. According to
self-synchronizing theory, rotational movement of the two sets of
vibration motor will follow each other and synchronized reverse
rotation can be realized in a short time if certain conditions are
met.
According to force center theory and coincidence with each other
the center of force of vibration exciter and center of mass of
vibration participants, excitation force will bring the entire
screen box to make vibration movement that has cyclic variation and
elliptical trail. Each and every point of screen box vibrates with
identical direction and intensity.
