The planer is a linear motion machine tool that uses a tool to plan the plane, groove or formed surface of the workpiece. Because the tool holder at the front of the ram is shaped like a bull's head, it is also called a bull head planer. It is mainly used for single-piece, small-batch production and machine repair workshop.

1, the coupling eccentric or poor lubrication; find or fill the grease;
2, the motor failure; check the motor;
3, reducer abnormalities; check the bearings and gears;
4, poor installation of the shaft seal; check the shaft seal;
5, shaft deformation or wear; parking disintegration inspection.
(B) high temperature gear pump flow is not enough, the fault reason:
1, suction or discharge valve closed; confirm whether the valve is closed;
2, the inlet pressure is low; check the valve is open;
3, the export pipeline blocked; confirm the discharge is normal;
4, stuffing box leakage; fastening, a large number of leaks affect production, should stop running, dismantling inspection;
5, the speed is too low; check the actual speed of the pump shaft
(C) high temperature gear pump suddenly stopped, the cause of the malfunction:
1, blackout; check the power supply;
2, motor overload protection; check the motor;
3, the coupling is damaged; open the safety cover, disk inspection;
4, the export pressure is too high, interlocking reaction; check the instrument interlocking system;
5, abnormal bite into the pump; after parking, positive and negative reversing confirmation;
6, sticking shaft and bearing stuck. Turn the car to confirm.
(D) high temperature gear pump can not discharge, the cause of the malfunction:
1, the direction of rotation is reversed; confirm the direction of rotation;
2, suction or discharge valve closed; confirm the valve is closed;
3, the entrance without material or pressure is too low; check the valve and pressure gauge;
4, viscosity is too high, high temperature gear pump can not bite material. Check the liquid viscosity, low-speed operation by the speed ratio of the flow rate appears, if the flow, the inflow is insufficient.
High temperature gear pump troubleshooting
(A) high temperature gear pump sound abnormalities, the cause of the malfunction:
