Reducer lubrication is not in place
The requirements of the reducer for lubrication are very strict. If the lubrication is not in place, the effect on the use effect is great. Not only is the work efficiency not guaranteed, but it is also likely to shorten the life of the equipment. In order to let the majority of users realize the importance of lubrication, GM summarized the hazards of several planetary reducers not being lubricated.
If the accelerator is not in place, it will cause loud noise and vibration, which will result in frequent maintenance. Moreover, for each inspection, the eccentric bearing and the pin sleeve must be replaced, so that the maintenance cost is increased. The work of the bearing is not very stable. Due to the action of gravity and the vibration generated by the mechanical movement, the bearing will inevitably cause a slight displacement in the axial position. This relative movement is very harmful, and the continuous impact may cause the elastic retaining ring. The deformation and breakage cause the risk of the bearing falling off the shaft. Even if the bearing does not fall off, it will cause a lot of noise due to vibration.
Then the impact on the service life is relatively large, because frequent maintenance, it is necessary to disassemble the equipment, which will also have an impact on the parts that are not damaged, so for the whole machine, the lubrication will not be shortened. life.
The lubrication of the reducer should start from several aspects such as lubrication cycle, lubrication method and lubricant quality. Even if only one aspect is not in place, it will not get good lubrication effect. I hope you can pay more attention to lubrication and maintenance.
How to solve the problem that the worm gear reducer is difficult to start
In view of the difficulty in starting the worm gear reducer, some people advocate that the pump should be replaced or the pump should be lifted up: someone asks to change the motor: the engineer says: u pump and motor do not change, the pump depth does not change, very It may be that the worm gear reducer is unbalanced. The balance weight of the worm gear reducer is too light or too heavy, and the balance radius is not suitable, which often makes the worm gear reducer difficult to start. Especially in the new well extraction, due to the lack of information such as the liquid surface, it is impossible to calculate the balance weight and balance radius accurately when designing the machine, rod and pump. This allows the installation team to install the machine, according to the design of the balance radius of the balance block, does not necessarily guarantee the pumping balance.
If the oil production team does not re-balance the balance, the production will start, and the problem will arise. When the imbalance is severe, the worm gear reduction opportunity will not start. When the power curve shown in Figure 3-8 was measured by the power curve meter, it was found that the worm gear reducer was seriously unbalanced, and the balance ratio was only 46.7%.
