Gear Oil Purification unit for Pumping Unit

Pumping unit is the core equipment of oil production. If the gear oil of the gearbox of the pumping unit is seriously polluted, it will cause abnormal operation of the pumping unit, such as oil leakage on the output shaft and increased workload. Daily maintenance of pumping units will increase the unit cost of oil production, reduce oil production and even cause environmental pollution.

We have developed a series of pumping unit reduction box output shaft oil leakage prevention devices, pumping unit reduction box gear oil online purification devices and pumping unit lubricants offline Purification device through in-depth practice in various domestic oil production lines.

I. Gear oil purification device for pumping unit on site

This device is used in various pumping unit production units and pumping unit repair units, and is used for the centralized purification of gear oil produced by the pumping unit test unit and the separation and purification of the oil sludge generated during the pumping unit repair process.

The device extracts the gear oil in the gearbox of the pumping unit online, and at the same time flushes and extracts the water and solid impurities deposited in the gear oil tank. Then, a multi-stage purification device is used to store the filtered water, solid impurities, colloids and asphaltenes in the impurity storage tank to purify the gear oil to NAS level 7 or higher, and re-inject it into the gear oil tank to reduce the probability of oil seal leakage, oil return groove blockage, and gear oil contamination , prolongs the service life of the reducer and gear oil of the pumping unit, and reduces the maintenance rate. The device has the following functions:

l  To detect the gear oil level and add new oil into gear box of pumping units

l  To flush and clean the gearbox

l  To purify the gear oil

l  To balance the pressure inside and outside of the gearbox

l  To store the waste separated from gear oil

II. Fixed gear oil purification equipment

The equipment is developed to purify the polluted gear oil collected from pumping unit maintainence centers and pumping unit manufacturers.

It adopts electromagnetic heating, ultrasonic demulsification, high-efficiency chemical flocculation, centrifugal separation, membrane filtration and other technologies to efficiently separate water, solids and gear oil from the contaminated oil. And then purify the gear oil for reuse.
