Effective measures to reduce the probability of drilling rig failure.
The correct maintenance method to reduce the probability of drilling rig failure:
One: to ensure normal working load

The service life of the drilling rig is related to the wear of the parts.
When the parts are worn and the bearing capacity remains unchanged, the uneven surface caused by wear will
increase the surface stress concentration and accelerate the wear. The parts in the rig can affect the stability of the rig and cause mechanical failure.

Two: Minimize the impact of harmful factors


1. Reduce the impact of impurities


During the use of the drilling rig, some impurities such as dust and metal chips will be contaminated, which may endanger the use of the rotary drilling rig. In order to reduce the damage caused by impurities to the machine, it is necessary to clean the drilling rig, use lubricating oil to ensure the complete sealing between the connecting parts, and do a good job of cleaning the construction site of the rotary drilling rig to prevent dust and other impurities from entering the interior of the drilling rig. During on-site maintenance, the ground should be dust-reduced to prevent dust from entering the engine.

2. Reduce the influence of temperature

The high temperature of the drilling rig will affect the use of parts and even cause damage to the engine. Each part has a normal working temperature value. Generally speaking, the temperature of the cooling water is 80-90 degrees Celsius, and the temperature of the hydraulic oil of the hydraulic transmission system is 30-60 degrees Celsius. When the drilling rig runs at low temperature, it is necessary to start the engine to preheat to prevent the engine from malfunctioning because other components have not yet started to work. Similarly, in a high temperature environment, before starting the rotary drilling rig, check all the instruments to observe whether the readings are normal and check the faults. to start running.

3. Reduce various corrosive effects

Most parts of the drilling rig are metal surfaces, so it is necessary to pay attention to the chemical corrosion of the surface, avoid direct contact with rainwater and air, and apply lubricating oil or spray paint on the surface to prevent accelerated wear of the machine.

Three: timely maintenance

Each part of the drilling rig has a maintenance cycle, so it is necessary to repair and maintain each part of the drilling rig according to the length of use.

Four: ensure reasonable lubrication of machinery There are three main failure modes of drilling rig parts: wear of the working surface of the parts, corrosion of the surface of the parts and aging of the material, of which the failure caused by the wear of the working surface of the parts accounts for the largest proportion. Ensuring the reasonable lubrication of the drilling rig is an important way to solve the wear of the working face of the parts. The use of good materials, exquisite craftsmanship, and reasonable structural design are also important factors to ensure reasonable mechanical lubrication.
