The advantages and disadvantages of submersible pump The advantages of submersible pump: 1. Large displacement liquid production is the main advantage of this oil recovery method. However, submersible pumps are also often used in oil wells with low liquid production. 2. This pump is capable of transferring water from the well above the aquifer into the lower aquifer. 3 simple operation, easy management, application in urban areas have landscaping to reduce noise. 4. Can be better used in inclined shafts, horizontal wells and offshore oil production. 5. Easy to handle corrosion and waxing. 6. Easy to install downhole pressure and temperature test equipment, and the test signal transmitted to the ground via cable, the measurement readings. 7. In order to adapt to the production decline or change in oil well, frequency conversion device can be used to adjust the power frequency to achieve, but the higher input costs. 8. A longer maintenance-free, well-time production is relatively high. Submersible pump shortcomings: 1. The depth of the submersible pump into the depth of the motor rated power limit, casing size and downhole temperature of the submersible pump into the depth limit. Large, high-powered devices do not have enough ring-shaped space to cool the motor, reducing the life of the motor. 2. As multi-level high-power submersible power is more expensive, making the initial investment is relatively high, especially the higher the cost of the cable. If you need to engage in corrosion or high temperature, the cost will be higher. 3. As the entire unit is installed downhole, in the event of a failure, the entire string needs to be repaired, resulting in increased operating costs and downtime. 4. Underground high temperature easily lead to cable failure, high temperature, corrosion and wear may cause motor damage. A high gas-oil ratio will cause the lift failure to be reduced and the pump will fail due to the air lock. 5. Power source only adapt to the use of power.
Sodium street light housing
Sodium street lights are known for their high efficiency and long lifespan, making them a popular choice for municipalities and other organizations looking to reduce their energy consumption and maintenance costs. They are also highly resistant to weather and other environmental factors, ensuring that they remain functional and reliable even in harsh conditions.
In addition to their practical benefits, sodium street lights also offer a number of aesthetic advantages. Their warm, yellowish light is often preferred over the harsh, bluish light produced by other types of outdoor lighting, and can help to create a more inviting and pleasant atmosphere in public spaces.
