    On January 6, it was learned from the oil and gas storage and transportation workshop of Yan'an Petrochemical Plant that the workshop implemented the "one reduction and one reduction" optimization transformation of the propane pump, and the operation results in the past year showed that the operating time of the pump was extended from a maximum of 65 days to 8-11 months, and the transformation effect was obvious
    .

    It is understood that the propane pump is mainly to transport raw materials
    to the light hydrocarbon center of the plant.
    Since it was put into use, there have been multiple pumping, pump vibration, noise gradually increased, etc.
    , the upper and lower shaft connections are easy to loosen and wear, accelerate the damage of consumable parts in other parts, and the operating cycle is only about 45-65 days
    .

    To this end, the oil and gas storage and transportation workshop finally decided to optimize the pump outlet pressure, head and pump structure by consulting relevant materials, consulting relevant experts, and analyzing operating data on site
    .

    "During the transformation, we removed the lower shaft part of the pump (including the first impeller, induction wheel, etc.
    ) and the second, third and fourth stage impellers, and the pump outlet was reduced from 3.
    27 Mpa to 1.
    9Mpa-2.
    1 Mpa, and met the process requirements
    .
    " Wang Hongfa, deputy director of the workshop, said that since the implementation of the transformation at the end of 2021, the pump has run smoothly, the operating cycle has been extended to 8-11 months, and the maintenance cost can be reduced by more than 200,000 yuan
    per year.
