In the course of work, it inevitably will shake for various reasons. If long-term
vibration will cause the loosening of the screws and other parts or even fall
off, which is the reason why we emphasize the need to be tested and regular
maintenance to equipment. How can we reduce the the Sand maker shock? I will
tell you some methods.
1 Spiral wire rope isolator. As a damping
element, the wire rope, with a low frequency ofthe variable parameters of the
high frequency and low stiffness of the large dampingperformance, which can
effectively reduce body vibration. Compared with the traditionalrubber vibration
source, anti-oil, anti-corrosion, anti-temperature, high temperature resistance,
aging resistance as well as the advantages of small size, isolation
effectdepends primarily on its nonlinear hysteresis characteristics.
2,
hydraulic isolation. The hydraulic support system is one of the structure of
conventional rubber bearing with hydraulic damping, can provide larger damping
in the low frequency range, large amplitude vibration play a role in the rapid
decay of the engine in the high frequencies with low dynamic stiffness can
effectively reduce cab vibration and dry sound.
3, the rubber isolator.
Conventional engine with elastic supports to reduce vibrationisolation mounting
structure is simple, low cost, reliable performance. Rubber bearingsare
generally mounted on the frame, the force is divided into the compression type,
shearand compression and shear complex.
Reverse the action principle is
reversed in the past the solution to the problem or operating. One of the
methods of this principle is to allow the movement of raw materials to be
crushed, so that the hammer stationary, jet mill, this crushing principle, but
the principle for the cereal raw materials, can reduce energy consumption to be
studied.
Mechanical vibration principle is to make the instigation of the
object in vibration situation or increase its vibration frequency, even up to
the ultrasound. The principle prompts us to increase the mechanical vibration in
the grinder, so that the crushing process in a dynamic state. Vibration can be
crushed parts, sieve plate, rack, and combinations thereof. Grinder in a state
of vibration, vibration mill is an example of.
Hammer crusher, of which
grinding parts in the vibration state, will surely be able to improve the
grinding efficiency to reduce energy consumption. But it still needs research
and testing about how to take specific implementation.
Another example is the
hammer mill sieve vibration can improve the rate of sifting to reduce the crush
to reduce energy consumption, this principle has been successfully applied to
ultra Deng aid: use of TRIZ hammer mill, horizontal wide vibrating
screen hammer smash on machine products.
