Debugging and operation

First, correct power connection is performed. The mechanical unit is debugged when leaving the factory, and a hydraulic system is mainly debugged on site.

Use and maintenance of equipment

Use of the device

Firstly, the lubrication of the positioning V block sliding plate is detected, and 3# lubricating grease is added.

Detecting whether all wiring of the equipment is correct, whether all hydraulic joints are reliably connected, whether all connecting screws are firm and whether lubricating pipelines are reliably connected;

when the device is used, firstly, lubricating oil is pumped into each lubricating point by a manual oil pump, whether the lubrication of each bearing is good is checked, then the night oil pump is started after the lubrication is good is confirmed, the device starts to operate after the system pressure is adjusted to 100MPa, in the operation process of the device, when the device operates to a position where a pipe needs to be lifted, a travel switch sends a signal, the operation of a cart is stopped, a hydraulic cylinder starts to act, the pipe is lifted to the upper dead center position, the operation of the cart is stopped after the cart starts to operate to a conveying belt, a lifting mechanism falls down to place the pipe on the conveying belt, and the cart returns.

Maintenance of equipment

In order to ensure the safe and reliable operation of the equipment, the mechanical, electrical and hydraulic pressure of the equipment are required to be checked every day, whether the motion of each motion part of the equipment is flexible or not is noticed at any time, whether the equipment is stable or not in the motion process is noticed at any time, a manual oil pump is used for oiling each lubricating point every week, and the exposed parts of a guide rod and an oil cylinder piston are kept clean and free of impurities.

Firstly, the bearing seat should be injected with lubricating grease once per shift.

Samples were taken and checked for oil color and viscosity change.

The lubricant is inspected for impurities, foreign matter or metal particles.

Secondly, if the bearing works for a long time, the following problems should be noticed:

a. a monitoring or vibration sensor is required to detect the sound quality of the bearing, and clear and regular sound indicates that the equipment is normal;

b. the temperature of the bearing as it rotates increases. The higher the speed, the higher the temperature. After a certain time, the maximum temperature is reached, and then the temperature slowly drops to reach a stable value. If the temperature suddenly rises and continues to rise for a long time, it is an abnormal phenomenon. The plant must be shut down, the cause determined and appropriate measures taken to correct the problem. Therefore, the temperature must be measured at the same site periodically.

And thirdly, immediately increasing the current value of the driving motor after starting, then immediately decreasing and returning to a normal value. If the current is always large, it should be considered abnormal and appropriate steps taken to eliminate this.
