Automatic water supplementing device for cooling water pipeline of oxygen compression section mechanical seal

Abstract

This utility model discloses an automatic water replenishment device for cooling water pipelines of mechanical seals in oxygen press sections, relating to the technical field of mechanical seals in oxygen press sections. The utility model includes a rotating shaft with a sealing sleeve on its outer side. A water inlet pipe is located on one side of the sealing sleeve. An electric contact pressure gauge is used, with a set pressure value. One end of a branch pipe is connected to the production water. Cooling water enters the interior of a filter cylinder through a guide pipe, facilitating filtration of the production water under the action of the filter cover. The filtered water enters the interior of the sealing sleeve through a connecting pipe and the water inlet pipe to cool the mechanical seal. After cooling, the water is discharged through an outlet pipe. When the pressure of the cooling water inside the connecting pipe is lower than the set pressure, a pneumatic stopcock valve opens, increasing the cooling water pressure and triggering an audible and visual alarm. When the water pressure exceeds the set upper limit, the pneumatic stopcock valve closes, and the audible and visual alarm stops.

Description

Technical Field

[0001] This utility model belongs to the field of mechanical seal technology for oxygen pressure section, and in particular relates to an automatic water replenishment device for cooling water pipelines of mechanical seals in oxygen pressure section. Background Technology

[0002] In the oxygen pressure section, mechanical seals are key components of rotating equipment such as oxygen compressors and pumps, used to prevent high-pressure oxygen leakage. Due to the strong oxidizing properties of oxygen and the risk of combustion and explosion under high pressure, the design, material selection and maintenance of mechanical seals must strictly follow safety regulations.

[0003] During the production process, the mechanical seal plays an important role in the operation of the centrifugal pump. When the mechanical seal lacks cooling water for a long time, it will be damaged. When the mechanical seal lacks cooling water, the operator cannot detect and deal with it in time. Therefore, automatic water replenishment of cooling water pipeline is particularly important. Moreover, the existing mechanical seal cooling water pipeline is mostly connected to the production water. The production water contains a lot of impurities. If the impurities enter the mechanical seal, they will affect the mechanical seal.

[0004] To address these issues, we provide an automatic water replenishment device for the cooling water pipeline of the mechanical seal in the oxygen pressure section. Utility Model Content
