There are flow switch and pressure switch installed on the oil tube of the pyz1200 cone crusher, and there is temperature switch on the oil return pipe. Operators can control the working process of the pyz1200 cone crusher according to the information provided by these switches. This article will introduce you the lubrication controlling system of the pyz1200 cone crusher.

The oil flowing protection:

The aim of the oil flowing protection is that prevent damages of the pyz1200 cone crusher because of the lack of the lubrication oil. It is achieved by the oil flow switch installed on the oil tube.

During the operation of the pyz1200 cone crusher, the temperature of the lubrication oil is required to not exceed 140 degrees, so there is a temperature switch installed on the oil return tube. After the oil pump being started, when the values of the oil pressure and the oil flow has reached their set value, the computer detects that the signals are normal and sends the output signal, and then the pyz1200 cone crusher will be powered on.

The oil pressure protection:

The aim of the oil pressure protection is that protect the pyz1200 cone crusher from broken because of the low oil pressure or the poor quality lubrication oil. It is finished by the pressure switch installed on the horizontal axis of the crusher.

If the oil pressure is lower than the set value, the site controlling box and the operation station will send alarm signal. Then the equipment stops feeding immediately. If the protection switch continues to work 90s, the motor of the pyz1200 cone crusher will be powered off.

The aim of delaying 90s is that endure materials in the crushing chamber are crushed completely. If the pressure of the oil recovers the set value, the master machine will automatically reset and restart feeding for the equipment.
