We have already introduced a lot about the ball press machine, here is to add again, the characteristics of the ball press machine and the ground loop circuit.
The ball press is mainly used for pressing powdery materials that are difficult to form. It is characterized by high forming pressure, adjustable main machine revolutions, and is equipped with a screw feeding device.
The host is powered by an electromagnetic speed-regulating motor, which is transmitted to the drive shaft via a pin-pin coupling via a pulley, a cylindrical gear reducer. The active and passive shafts are synchronized by open gears. There is a hydraulic device behind the passive bearing seat.
The screw feeding device is driven by an electromagnetic speed-regulating motor, and is rotated by a pulley and a worm reducer to force the pressed material into the main feeding port. Due to the constant torque characteristics of the electromagnetic speed-regulating motor, when the amount of material held by the screw feeder is equal to the amount of material required by the host, a constant supply pressure can be maintained to stabilize the pellet quality. If the supply is too large, the electricity of the feeding device is overloaded; if the supply is too small, the ball will not become a ball. Therefore, skilled operation skills are an important condition to ensure the normal operation of the ball.
In the hydraulic protection device, a high-pressure oil is driven into a hydraulic cylinder by a hydraulic pump, and the piston is axially displaced. The front joint of the piston rod is pressed against the bearing seat to meet the production pressure requirements. When the feed between the two pressure rollers is too much or it enters the metal block, the hydraulic cylinder piston rod is overloaded by pressure, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open and return, and the piston rod will shift Enlarging the gap between the pressure rollers allows hard objects to pass through the pressure rollers, and the system pressure returns to normal, which can protect the pressure rollers from damage. The machine can adjust the pressure according to the requirements of the ball density, and the production is flexible.
The grounding of the ball press can be divided into internal electrical grounding and ground coverage. Shell ground is mainly used to prevent the accumulation of static electricity and leakage. Outdoor ball presses must also be equipped with external lightning protection measures. Generally speaking, the ground ball protection installed on the outdoor ball connected to the rotating machine due to the metal bracket has been formed naturally, and the protection against the ground fault cannot be done specially by the pole bracket housing. The data and video cables inside the ball press are handled on the ground in this yard and connected to GND to ensure that the equipment is effectively grounded to the ground ball machine. Ground loop closed loop Even if the equipment is effectively grounded, but the different zero components between the ball press and the center, the positions of the potential differences, no power load balance, will rise to the ground potential difference. Through the potential difference of the coaxial cable, a closed loop current is generated and generates interference, which affects the normal video signal transmission, which usually gives an intermediate level of image confusion. The most effective way to solve the loop, loop is to increase the video transmission to the central isolation.
