How to buy the best pumping unit
Beam pumping unit is the most commonly used oil recovery equipment in oilfield.
The pumping unit works outdoors all year round, and will be eroded by the harsh natural environment of rain, snow, sand and wind, which is prone to malfunction and lead to shutdown of the well.
If you want your pumping unit to operate reliably for a long period of time without problems, the pumping unit must be of the best quality.
How to buy a reliable pumping unit with low failure rate?
Please read the following article.
First, you should choose a reliable pumping unit manufacturer with a well-known brand name.
You should evaluate the manufacturer from four items.
The first is the certificate.
The second is productivity.
The third is quality control and delivery time, and the fourth is overseas after-sales service capability.
If you select a manufacturer and order a batch of pumping units, do they meet the requirements and are they of good quality? You can check the pumping units from the following items.
1). Running behavior. Under full load, the pumping unit runs smoothly without impact, vibration or abnormal noise.
2). Horsehead stability. The horsehead does not tremble when the pumping unit is running at full load.
3).Seal ability of finished product. After two hours full load operation of the pumping unit, all the seals have no leakage.
4). Reducer Bearing temperature rising stably.
After two hours full load operation of the pumping unit, the bearing temperature rise could not surpass 40 ℃ and the final temperature could not surpass 70℃.
5) Reducer oilsump temperature rising stably. After two hours full load operation of the pumping unit, the oilsump temperature rise could not surpass 40 ℃ and the final temperature could not surpass 70℃.
6). Noise level(dBA). After full load operation, use sound level meter to test, the measuring points distribute two ends of output shaft, calculate average value.
7). Donkey head hanging point projection
After running at full load for 2 hours, the theodolite should measure at least three points in the middle except for the upper and lower starting points.
8). Scissors difference between two cranks. After full load inspection, use mandrel to test, scissors could not surpass the following range.
9). Reliability of brake mechanism. Using the tensioner to guarantee the brake mechanism is steady and reliable, and when crank was in horizontal position, the brake force could not more than 150N. when release brake device, the brake sub and brake belt could not have any contact.
10). Contact area of two cranks and driven shaft. By coating red lead inspection, the upper and bottom contact area of wedge bond could not less than 80%, and every square centimeter should have contact points.
11). Adjusting counterbalance. Check for balance adjustment through handfeel inspection, the movement should be steady, no jamming.
12) Horsehead flip flexibility. By visual inspection, check that the donkey’s head turns flexibly and without any lag.
These 12 items must be inspected before beam pumping units leave the factory.
If all the items are up to standard, this pumping unit is a reliable product.
