The turntable is one of the main components of oil drilling equipment. It uses power to rotate to complete three major functions: 1. Rotate the downhole drilling tool to transmit a large enough torque and necessary speed; 2. In the process of casing running or tripping, all casing strings or drill pipes supporting the downhole can bear the weight; 3. Complete drill bit unloading and shackle, and carry out ancillary work such as undercut and buckle when handling accidents.
Various special vehicles often have oil leakage failures in the use of vehicles. Oil leakage failures will directly affect the use and productivity of the car, resulting in the waste of lubricating oil and fuel, the power and work efficiency of the car. Sanitation vehicles, engineering vehicles, vans; once the oil leakage occurs, the internal lubricating oil of special vehicles will decrease, which will lead to poor lubrication of parts and poor cooling of parts, resulting in damage to parts, affecting the service life of the vehicle, and even leaving accidents Hidden dangers. 1. The common causes of oil leakage in general vehicles are as follows: 1. Special vehicle parts quality problems, parts raw materials or manufacturing process problems; 2. Improper high-speed assembly, unclean mating surfaces, damaged gaskets, displacement or failure to install in accordance with operating regulations. 3. Uneven tightening force of the tightening nut, broken wire or loose and falling off, etc. lead to work failure. 4. After long-term use, the sealing material wears out excessively, deteriorates due to aging, and becomes invalid due to deformation. 5. Too much lubricating oil is added, the oil level is too high or the wrong oil is added. 6. Parts (side covers, thin-walled parts) on the joint surface are flexed and deformed, the shell is damaged, and the lubricating oil seeps out. 7. After the vent plug and the one-way valve are blocked, due to the pressure difference between the inside and outside of the case, oil leakage will often occur at the weak seal.
