What is the central nervous system pump?
Great popularity in industry, the mainthe purpose of which is oil production, purchased sectional pumps of the central nervous system, first appeared in early 1980. These pumps were designed to inject special aggressive waters into oil reservoirs. Also, hydrogen sulphide-containing waters were introduced in them. Thus, within the reservoir with oil, a certain pressure was maintained, which is necessary for the extraction of this valuable substance.
After many years of studying the necessarydocumentation and materials, as well as taking into account the wishes of customers, the CNS 180 pump was modernized in the design field. This was done in order to increase the service life, reliability and maintainability of the system. During the modernization, the following directions were changed:
1. A new flow system was used, namely the newest impellers were introduced, which direct all the necessary equipment.
2. The CNS pump has purchased new end seals with a modern flushing system. In some cases, packing glands have been modified to facilitate the operation of the pump without leaks.
3. New rubber rings were installed, which are necessary to prevent erosion of the seats of the shaft and wheels.
4. Carbide-tipped rings were used in interstage seals.
5. A node was installed, which optimizes the unloading device.
6. As nodes for the connection, the CNS pump has acquired a flexible plate clutch.
7. A shear sensor was mounted on the axis with the alarm, which was activated after reaching the maximum allowable wear of the hydrotreater.
When creating all the newest nodes wereSoftware tools were used to simulate a particular process (or part). After checking all systems on CNC machines with high accuracy, the result was positive. In reality, all the characteristics have changed by only one percent. The upgraded central nervous system pump has acquired the following characteristics:
1. The work capacity was increased almost threefold.
2. The maximum allowed working area has been extended.
3. Increased efficiency in the operation area.
4. Also, the external leakage, the level of vibration to the minimum mark, was reduced.
5. Access to the necessary nodes has become easier.
6. The assembly system has become simpler.
7. The design of the pump has become much more attractive.
At present, the production of these systemspasses in special shops and departments, which are equipped with the most modern devices. At all stages of creation, starting with the smelting of metals and ending with the creation of parts, complete control over compliance with all necessary parameters is used.
The designers also proposed an ideaoptimize the central nervous system pump by installing new flow systems, which will facilitate the transfer of the optimal feed rate by about 120 m3 / h. It can be done and so that the translation occurred at 240 mz / hour. Electric motors in this case will be used former, not subjected to any changes.
