The piston is one of the main moving parts of the
engine, is composed of combustion chamber components. Engine Piston Parts,Engine Parts ,Car Engine Parts,Parts Of Engine,Piston Engine Parts ZhouShan HeCheng Machinery Co., LTD. , http://www.hcmarineparts.com
 Ultrasonic vibration sieving system is composed by power supply of the ultrasonic resonance , oscillator and resonant ring. The high frequency electric oscillation produced by the ultrasonic resonant power supply is transformed into high frequency 3D oscillation wave by the oscillator. The oscillation wave is then transferred to the resonant ring which then transfers the vibration evenly onto the mesh surface. The ultrasonic vibration together with the 3D low frequency vibration prevents mesh blocking, and meanwhile improves the sieving output and quality.

Main features :
1. The screening precision of our circular vibrating screen is excellent, and the blocking rate of the screen is less than 5% in average. 2. The movement locus and vibration amplitude are both adjustable. Any granular, powdery and serous materials could be roughly screened, or just filtered according to the material applications. 3. The screening machine is 500-2000 mm in diameter, and the overall size is quite small. Wheels can be mounted on it for convenient moving. 4. The screen frame of the circular vibrating screen is specially designed. It takes only 5-10 min for the screen changing. The stainless steel wire woven net is easy to clean and operate, while the life span is quite long. The wheel, viewing hole, and frequency converter are available according to your requirements. 5. Completely enclosed structure is adopted so the particulate matter pollution in the air is quite limited. 6. The discharging outlet can be rotated at 360 degree, facilitating the installation of matching equipment. 7. The energy consumption of our circular vibrating screen is small, while the noise could reach as low as 75 dB
8. During the operation, if short circuit, phase loss or unstable voltage occurred, the motor will automatically cut off the power supply and stop working to make sure the motor will be not burnt out. Thus the electric element's damage can be reduced to an extremely low level.Â
Â
9. The protective grade of the motor comply with IP65, which means it is dustproof and waterproof. Besides, it is also heatproof and oil proof.Â

The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed Diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
