Product Description

Conventional beam crank balanced pumping unit structure. Structural features: crank connecting rod mechanism and donkey head are located on both sides of the bracket respectively, the crank shaft (reducer output shaft) center is basically located in the tail of the beam bearing seat below.
Main structural features:
1, the machine structure is reasonable, stable work, low noise, simple operation and maintenance;
2, travel beam selection box type or I-beam structure, high strength, good rigidity, stable and reliable;
3, reducer adopts herringbone double circular arc gear, strong load resistance, long service life;
Beam pumping unit maintenance is relatively simple, but it must be according to the requirements of the manual to check the lubrication points regularly, regularly check the connectors, fasteners, brake pad wear, pumping unit balance.

• Common fault diagnosis
  1. The crankpin is making a harsh sound. The possible cause is that the cap of the crankpin is loose. At this time the crank pin cap should be prepared tightly.
  2. The reducer appears regular sound (gear impact sound), it proves that the balance is not good, need to adjust the balance. If the reducer appears irregular sound, this time may be the bearing is broken, need to repair the reducer.
  3. If the temperature of the reducer spindle bearing rises abnormally and the iron pin splashes, the reducer should be short of oil at this time. It is necessary to check the lubricating oil condition and the damage of the reducer bearing and gear.
  4. If there is a sound at the top of the donkey head, it may be the middle seat bearing is broken, and the end cover of the middle seat grinding shaft. At this time should check the donkey head installation is not correct, at the same time check the seat.
  5. If there is an irregular sound without a certain place, it may be that the force of the pin is not good, and the sound of structural parts trembling.
  6 reducer oil leakage, since the reducer box surface or bearing cover oil leakage, may be too much lubricating oil; The shell is poorly combined or the oil drain wire is not plugged tightly. At this time, check the oil level, tighten the box bolts evenly, or wash the dividing surface of the box, and evenly coat the W-2 sealant before closing the box. Tighten the drain wire plug.
  7. When the donkey's head squeaks during operation, it may be that the wire rope is dry due to lack of oil or the wire rope is broken. At this time, oil the wire rope or replace the wire rope.
