How to choose the engine oil required by Horizontal Directional Drilling Machine?

1. Selection of engine oil required by Horizontal Directional Drilling Machine.

<1> It must not be possible to add different engine oils to the same chassis at the same time. When the temperature is relatively low, it is necessary to replace the engine oil of the Horizontal Directional Drilling Machine frequently. However, when we add new oil to the Horizontal Directional Drilling Machine When using engine oil, be sure to use up all the previous engine oil before replacing it.

<2> Do not add oil to the chassis of the Horizontal Directional Drilling Machine when it is hot. When changing the engine oil, be sure to shut down the Horizontal Directional Drilling Machine that is started, to ensure that the engine oil in the Horizontal Directional Drilling Machine and Only when the temperature of the engine oil to be added is about the same, can the engine oil be added.

<3> When adding engine oil to the Horizontal Directional Drilling Machine, it must be appropriate and not too much.

2. Precautions for installation of horizontal directional drilling guide wheel

(1) The symmetry of the center line of the round hole of the pin at both ends of the guide wheel shaft of the Horizontal Directional Drilling Machine is out of tolerance. After assembly, the longitudinal center line of the guide wheel does not coincide with the longitudinal center line of the track frame.

(2) The centerlines of the round holes of the device pins at both ends of the guide wheel shaft are not parallel, and the guide wheel device is formed to tilt.

In addition, if the guide wheel has processing defects, it will also cause "rail gnawing". For example, when the central shoulder of the guide wheel is lowered, an axial offset occurs, and the diameters of the raceways at both ends are different, so that the tension force of the two car belts is different, and it is easy to carry. Moving sweat, the raceway busbar is not parallel to the axis of the car belt pin, which makes the track partially slip.

Horizontal Directional Drilling Machine, the "rail gnawing" caused by the rollers Horizontal Directional Drilling Machine, the role of the rollers is to transfer the weight of the machine to the eyebrow belt.

When the machine is moving, in addition to rolling along the rail surface of the track, it also clamps the track to prevent it from slipping laterally. When the machine turns, it also makes the track slide laterally on the ground. Rollers are divided into unilateral and double sides.

3. The main reasons for horizontal directional drilling support rollers to "gnaw rails" are:

(1) The fixing bolts of the supporting wheel are loose, causing the axial position of the supporting wheel to change or skew.

(2) The center flange of the supporting wheel is offset during processing.

(3) The raceway generatrix is not parallel to the track pin axis to make the track slide sideways.

(4) The diameters of the raceways at both ends of the rollers are different.

(5) When the supporting wheel is processed, the axial dimension of the raceway is too small, so that the gap between it and the track is smaller than the gap between the guide wheel and the track, causing "rail gnawing".
