The selection method and precautions for petrochemical gear oil pumps are the same as the fault factors

[1] The selection method and precautions for gear oil pumps should be based on the specific usage requirements of the customer when selecting stainless steel oil pumps

Secondly, it is necessary to clarify what medium is being transported by the gear oil pump and what its viscosity is

3. What is the actual temperature of the gear oil pump during use

4. When using the gear oil pump, the required working pressure, actual length of the pipeline, height of the high point, and the number of bends in the middle of the pipeline are required

Fifth, it is necessary to reasonably calculate the actual pipeline resistance and pipeline loss of the gear oil pump and gear pump based on the actual pipeline situation of the customer

6. Is the medium actually transported by the gear oil pump corrosive, what is the specific pH value of the medium, and whether the corrosiveness of the medium changes with temperature in actual use

7. Is the medium conveyed by the gear oil pump lubricating, contains particles, or is prone to crystallization

8. Does the gear oil pump exhibit forward and reverse rotation during use. If reverse pumping is sometimes used during use, it should be noted when ordering. Because reverse rotation is prohibited when gear oil pumps are equipped with mechanical seals, and the use of reverse rotation in conventional gear pump oil pumps can cause gear detachment

9. When the gear oil pump needs to work at high temperatures, it should be specified when ordering

[2] Fault factors and solutions of stainless steel gear pumps

The design of stainless steel gear pumps also considers the lubrication of bearings during operation and the performance of other components. The use of a separate bearing and pump chamber external lubrication structure has changed the traditional structure of using conveying media to lubricate bearings in the original gear pump, and improved the transmission accuracy of the main components.

. The delivery temperature of stainless steel oil pumps is generally between 20 ℃ and 180 ℃, and the structure can reach up to 250 ℃

Solution to stainless steel gear oil pump failure

1: The power transmission gear and fluid delivery gear are located in different pump chambers, and they are designed and manufactured according to their respective functions, so the pump has high performance.

On the basis of the pump type, support is added to increase the working pressure, and it is designed as a flange connection. There are two forms of gear pump mechanical seal and packing seal

The leakage of water or air in the stainless steel gear oil pump pipeline may also be due to improper installation of screw caps. If there is a leak in the pump connection, you can tighten the nut by hand. In severe cases, it needs to be disassembled and reassembled. The reasons for the severe vibration of the pump are combined with the imbalance of the electric rotor or poor coupling, wear and bending of bearings, loosening of rotating parts, and unstable support of broken pipelines. Measures such as adjustment, repair, reinforcement, straightening, and replacement can be taken separately
