The CNS sectional pumps, which first appeared in the early 1980s, have become very popular in the industry, the main purpose of which is oil production. These pumps were produced for the purpose of pumping special aggressive waters into oil-bearing formations. Hydrogen sulfide-containing waters were also introduced into them. Thus, a certain pressure was maintained inside the reservoir with oil, which was necessary for the extraction of this valuable substance.
After many years of studying the necessary documentation and materials, as well as taking into account the wishes of customers, the CNS 180 pump was modernized by professionals 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 areas have undergone changes:
1. A new flow system has been applied, namely, the latest impellers have been put into use, which guide all the necessary equipment.
2. The CNS pump has acquired new end seals with a modern flushing system. In some cases, the gland seals have been modified to help the pump run without leakage.
3. New rubber rings were installed, which are necessary to preventscour shaft and wheel seats.
4. Carbide rings were used in the interstage seals.
5. A node has been installed that optimizes the unloader.
6. As nodes for connection, the CNS pump acquired a flexible plate coupling.
7. A shift sensor was mounted along the axis with an alarm that turned on after reaching the maximum allowable wear of the hydraulic foot.
When creating all the latest units, software tools were used to simulate a particular process (or part). After testing all systems on CNC machines with high precision, the result was positive. In reality, all characteristics have changed by only one percent. The upgraded CNS pump acquired the following features:
1. The performance was increased almost three times.
2. The maximum allowable area for work has been expanded.
3. Increased work efficiency in the operating area.
4. External leakage and vibration levels have also been reduced to a minimum.
5. Access to the necessary nodes has become easier.
6. The assembly system has been simplified.
7. The design of the pump has become much more attractive.
Currently, the production of these systems takes place in special workshops and departments, which are equipped with the most modern devices. At all stages of creation, from metal smelting to the creation of parts,full control over compliance with all necessary parameters.
Designers also proposed the idea of optimizing the CNS pump by installing new flow systems that will help shift the optimal flow to about 120 m3/h. It can also be done so that the transfer occurs at 240 m3 / h. In this case, the electric motors will be used the same ones that have not undergone any changes.
