When the drilling rig friction pad wear, more needs to be adjusted periodically need to remove the adjustment nut fixing pin large drilling rig on the adjustment, turn to the right, the pins move into the new position of the cam ease the pressure plate closer. Rig friction film production will also appear in the production slip, the slip will also affect the production efficiency, this time you need to pay attention to the situation of lubricating oil, lubricating oil adding too much if it would cause skidding, the need for timely clean, Avoid excessive slippage impact drilling rig production process. Engineering hydraulic system in use will produce some pollution, such as pollution of oil, we should pay attention to other matters, the use to avoid contamination, and maintenance of hydraulic systems engineering rig, detailed precautions below. ① strengthen the management of hydraulic oil. Oil into the plant must sample check to confirm eligibility after the injection of a large storage tank Rig video production, the hydraulic oil in some of the particles precipitated, and inject the hydraulic system must also be filtered. ② hydraulic system of hydraulic oil rigs of major projects to periodic inspection works, the oil filter should be cleaned regularly or replaced. In strict accordance with the product manual and maintenance manual requests. Under normal circumstances, the new machine factory to replace the hydraulic oil and the oil filter cartridge systems used in factory test. If the hydraulic oil that has expired, to be replaced when the new machines use. Always check the degree of contamination of the hydraulic oil, hydraulic oil contamination if it is found, regardless of whether the period of use must be replaced. Oil contamination level determination and action scene in Table 2. ③ reasonable choice of filter. Flow oil filter, filtering accuracy and pressure must match the system, the filtration precision filtration system, generally based on the accuracy of the most sensitive elements to choose. Filter material used must have compatibility with the transmission medium. Hydraulic components for filtration accuracy requirements in Table 3, the hydraulic system of filtration accuracy requirements in Table 4. ④ prevent high oil temperature, hydraulic oil is strictly prohibited mix different grades.
