After the water well drilling rig leaves the factory, it is generally stipulated that there is a run-in period of about 60 hours (sometimes called run-in period), which is stipulated according to the technical characteristics of the water well drilling rig at the initial stage of use.However, at present, some users ignore the special technical requirements of new drilling rigs due to lack of common sense, tight schedule, or the desire to make profits as soon as possible.The drilling rig is overloaded for a long time during the run-in period, which leads to the frequent occurrence of early faults of the machine, which not only affects the normal use of the machine and shortens the service life of the machine, but also affects the progress of the project due to the damage of the machine.Therefore, the use and maintenance of water well drilling rig should be paid enough attention to.

 

The characteristics of run-in period are as follows:

 

1. Wear fast.Due to the influence of the processing, assembly and adjustment of new machine parts, the friction surface is rough, the contact area of the mating surface is small, and the pressure on the surface is uneven, which accelerates the wear of the mating surface of the parts.

 

2. Poor lubrication.Due to the small fit gap of newly assembled parts, and because of assembly and other reasons, it is difficult to ensure the uniformity of fit gap, lubricating oil (grease) is not easy to form uniform oil film on the friction surface, thus reducing the lubrication efficiency and causing abnormal early wear of the parts

 

3. Loose.New processing assembly parts, affected by factors such as heat, deformation, plus wear too fast and other reasons, easy to make the original fastening parts loose.

 

4. Leakage occurs.Due to loose parts, vibration and the influence of heat on the machine, the sealing surface of the machine and pipe joints, leakage will occur.

 

5.Operation error.Due to the insufficient understanding of the structure and performance of the machine, it is easy to cause failures or even operational accidents due to operational errors.
