The feeding and unloading device of machine tool is the automatic or semi automatic mechanical device which takes the workpiece to be sent to the machine tool and the workpiece is removed from the machining position, also known as the automatic loading and unloading device.

Throttle orifice choke causes are generally the following:
1. Mechanical contaminants in the oil, or colloids, asphalt, carbon slag, and other contaminants deposited by oxidation accumulate at the throttling gap.
2. Due to the aging of the oil or the extrusion of charged polarized molecules, there is a potential difference on the metal surface of the throttling gap, so the polarized molecules are adsorbed to the surface of the gap, forming a strong boundary adsorption layer, the thickness of the adsorption layer It is generally 5 to 8 microns, which affects the size of the throttle gap. When the above deposits and adsorbates grow to a certain thickness, they will be washed away by the liquid flow and then reattached to the valve port. In this way, the pulsation of traffic is formed.
3, valve port pressure is greater, due to the valve port temperature is high, the degree of liquid squeezed enhanced, the metal surface is also more susceptible to friction and the formation of potential differences, so the pressure difference is likely to produce blockage phenomenon.
Throttle valves need to be operated frequently and should therefore be installed in a position that is easy to operate. At the same time, pay attention to the media direction and the direction of the arrow marked by the valve body.
