Embodiment 1

[0042] Embodiment one: the specific implementation plan and steps of the cooling water supply device of a kind of deep well pump vertical motor sliding bearing of the present invention:

[0043] A: From the outlet main pipe of the deep well pump to the opening of the pump control valve (as close as possible to the pump outlet), use DN50 stainless steel welded process pipelines, and install a manual ball valve at a distance of about 300mm from the main pipe, that is, the first valve 1 as the device Install a digital display pressure sensor-6 on the pipeline behind the first valve 1 at about 400mm to monitor the inlet water pressure;

[0044] B: The pipeline installed with the first valve 2 passes through the filter barrel 8 and the filter 9 as the main water supply circuit of the device, and the pipeline installed with the third valve 3 in parallel is used as the backup circuit of the device;

[0045] C: Install the fifth valve 13, the fourth valve 4 and the digital display pre...

Embodiment 2

[0054] Embodiment two: the concrete operation control method of the cooling water water supply device of a kind of deep well pump vertical motor sliding bearing of the present invention:

[0055] Check to confirm that each valve is closed, and the power supply and connection of the digital display pressure sensor, the control box 11 and the monitoring computer of the centralized control center are normal;

[0056] After the motor starts, slowly open the first valve 1 and adjust the pressure value of the digital display pressure sensor 16 to 0.25Mpa; then slowly open the second valve 2 to supply water to the filter bucket 8, and at the same time properly open the exhaust valve 14 to discharge until the air in the barrel is exhausted, the second valve 2 is fully opened, and the exhaust valve 14 is fully closed;

[0057] Then slowly open the fifth valve 13 and the fourth valve 4, and observe the pressure value of the digital display pressure sensor 2 7 at the same time, until the...

Abstract

The invention discloses a cooling water supply device of a deep-well pump vertical motor sliding bearing and a control method thereof, and the cooling water supply device is characterized by comprising a water supply pipeline arranged between a deep-well pump outlet main pipe and a main motor bearing cooling water bin; a filter barrel is arranged on the water supply pipeline, a pressure sensor I and a pressure sensor II are respectively mounted on pipelines at the front end and the rear end of the filter barrel, the pressure sensor I and the pressure sensor II are respectively connected with a control box, and the control box is connected to a centralized control center monitoring computer; a second valve and a fifth valve are respectively mounted on pipelines at the front end and the rear end of the filtering barrel; a standby loop is arranged beside the filter barrel pipeline in parallel; a third valve is mounted on the standby loop; a first valve is mounted on a pipeline between the deep-well pump outlet main pipe and the pressure sensor I; and a fourth valve is mounted on the pipeline between the standby loop and the second pressure sensor. The problems that existing cooling water is poor in water quality, impurities are prone to entering, and cleaning needs to be interrupted are solved, meanwhile, monitoring and timely early warning of cooling water supply are achieved, and production safety is guaranteed.

Description

technical field [0001] The invention relates to the field of pipeline water transfer and transfer, in particular to a cooling water supply device for a sliding bearing of a vertical motor of a deep well pump and a control method thereof. Background technique [0002] In recent years, the continuous intensification of drought in various places has not only caused local production, living and ecological environmental problems such as water shortages and river cut-offs, but also brought huge pressure to local economic and social development. The impact of drought is not a single existence, but has deteriorated into a serious threat to many fields such as industry, agriculture, ecology and people's livelihood. The main reasons leading to such consequences are the uneven distribution of water resources and the lack of rational deployment and effective utilization. [0003] With the healthy development of the national economy and the continuous progress of the society, the nation...
