1. In the field application case:
the usage is from 11 months to 3 months of 2019 in 2017, respectively from 11 months after the winter starts each year to 3 months of the next year, the usage lasts for 5 months, and the period is defined as a period. The application site is fixed at a sewage recovery pond outside a 14 th water injection station of a victory mountain oil recovery team, a1 set of pressure meter automatic temperature control and heat preservation device is installed on a1 st sewage recovery pump, an adjacent 2 nd sewage recovery pump is selected as a reference object, data statistics is carried out according to the site application condition, and detailed data are shown in tables 1 and 2;
TABLE 1 automatic temperature control heat preservation device of sewage recovery pump pressure gauge statistical table (2017.11-2019.3)
Table 2 statistical table of replacement of sewage recovery pump pressure gauge (2017.11-2019.3)
