The coupler accessories have those parts, do you know

Release date:2017-11-03 Author: Click:

The coupler accessories are mainly: pump wheel, turbine, rotating shell, input shaft, output shaft and spoon tube. Usually, the rotation of the shell and the pump wheel are connected to the flange in the flange. Pump wheel and turbine wheel blades are called work, two, two are respectively connected with the input and output shaft, there is a gap between them, so the pump and turbine has the same radial size, cavity shape, together to form the oil chamber, the oil from the pump into the wheel, and follow the power machine rotates together, the role of oil under the centrifugal force, was thrown to the outside of the pump wheels, turbine blades forming high speed oil flow into the opposite direction, gradually slow down and flows back to the inside of the turbine inside the pump wheel, constitute an oil cycle. The absolute flow of a working liquid in a working cavity is a three-dimensional motion.

When working overload, large circulating motion of working fluid can be quickly discharged into the auxiliary cavity below by means of dynamic pressure and gravity, so that motor and working machine can be protected from overload in time. If the auxiliary cavity is above, the direction of liquid flow is opposite to that of the auxiliary cavity when overloaded. It is necessary to rely on static pressure and overcome gravity to push liquid into the auxiliary cavity above, so its discharge speed is slow, and it is not as sensitive as the fluid coupling under the auxiliary cavity.

We are now in the northern cold area of our country as an example, the hydraulic coupling in North China oil pumping machine or ski use tractor, mostly used in the open air, in -40 percent under harsh environment can still normal operation. L-TSA32 turbine oil cut-off ordinary only reached -7%, 6 -30 hydraulic transmission oil doubts percent, No. 8 hydraulic transmission oil pour point is -35 percent were unable to use in the alpine region. Only in the 0/SYRH2042-2001 standard 8D hydraulic transmission oil pour point up to -50 percent, can be used outdoors in the cold area.
