The dewatering bucket elevator should ensure that the gear teeth have sufficient strength and wear resistance
The dewatering bucket elevator must be firmly installed on a solid foundation. The surface of the raft foundation should be level to ensure that the vertical requirements of the bucket elevator are met after installation. Through the analysis of bucket elevator wire rope friction transmission dynamics and anti-skid calculation, the greater the friction transmission force, the stronger its anti-skid ability. Therefore, increasing the friction transmission force of the bucket elevator or reducing the tension difference between the steel ropes on both sides of the transmission drum is both The necessary means to improve the anti-skid ability.
Increase the friction coefficient of the friction liner of the capstan wheel, strengthen maintenance and management to minimize water splashing in the wellbore, reduce oil pollution, enhance the warmth of the wellhead in winter, prevent the surface of the wire rope from freezing, and do not use expired and aging liners to ensure the stability of the friction coefficient. Using the counterweight single container to lift the counterweight single container lift under the condition of the same lifting amount at a time, the tension difference between the light load side and the heavy load side is half of the double container lifting time. Therefore, it has better anti-slip performance, but the efficiency is lower than that of double container. Increase the dead weight of the lifting container. Hang a counterweight at the appropriate position of the skip to increase the dead weight of the container, which also improves the pulling force of the steel wire rope on the light-load side and improves the anti-skid ability.
The sprocket of the dewatering bucket elevator is used to mesh with the block with accurate pitch on the link chain or the cable. It is a solid or spoked gear that meshes with the roller chain to transmit motion. The unique design of the sprocket of the bucket elevator lies in the tooth profile of the sprocket. The tooth profile of the sprocket must ensure that the chain enters and exits the mesh smoothly and freely, and minimizes the impact and contact stress of the chain link during meshing. Easy to process. The sprocket material should ensure that the gear teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat treated to make it reach a certain hardness.
Add an appropriate amount of grease to the reducer and housing. The reducer is lubricated with industrial gear oil. The shell can be calcium-based or sodium-based butter.
After installing the shell of the dewatering bucket elevator, install the chain and hopper. The U-shaped screw used for the hopper connecting rod is the holder of the connecting joint and the hopper. The U-shaped screws and nuts must be tightened and fixed firmly to prevent loosening. When installing a bucket elevator with a lower height, the upper, middle and lower cabinets can be connected and aligned on the ground to fix the entire suspension on the foundation. After installing the chain and hopper, please tighten properly.
Increasing the wrapping angle between the steel wire rope and the friction drum increases the wrapping angle between the steel wire rope and the friction drum, which can obtain greater transmission friction. However, the wrap angle of the bucket elevator is not only an important parameter that affects the anti-skid performance, but also an important data for installation design, and the increase of the wrap angle also has a significant impact on the service life of the wire rope.
The gap must be less than 10mm. The upper and lower shafts should be parallel, and their shafts should be on the same plane. The dewatering bucket elevator should be in the middle, and the appropriate position of the upper shell should be connected to adjacent buildings to improve stability. Install the lower part first, fix the anchor bolts, then install the middle shell, and then install the upper shell. Successfully install the chassis and correct the verticality. The total height of the lead is measured incorrectly.
