Mechanical sealing external circulation cooling system heat exchanger

Abstract

The invention discloses a Mechanical sealing external circulation cooling system heat exchanger. A cooling water inlet pipe opening, and an outlet pipe opening are formed in a heat exchanger tank body, a sealing separating liquid oil cooling coil pipe and a baffle sleeve are arranged in the heat exchanger tank body, a resistance induction probe (6) is arranged on the upper end part in the heat exchanger tank body, and an outlet filter (7) is connected with an outlet pipe opening of the sealing separating liquid oil cooling coil pipe. When the sealing separating liquid oil cooling coil pipe leaks, sealing separating liquid oil is floated on the upper part of a liquid storage tank, the resistance of the resistance induction probe (6) is from small to large after contacting the separating liquid oil, and display alarm is carried out, so that the phenomenon can be discovered and treated in time. The outlet filter is connected with the outlet pipe opening of the sealing separating liquid oil cooling coil pipe, impurities generated in a sealing separating liquid oil circulation pipeline can be prevented from being sent back into a mechanical sealing chamber, and the mechanical sealing lifespan can be prolonged.

Description

technical field [0001] The invention relates to a mechanical seal external circulation cooling system heat exchanger. Background technique [0002] The mechanical seal external circulation cooling auxiliary system is the guarantee mechanism to ensure the stable operation of the mechanical seal, including liquid storage tank, booster tank, pressure alarm device, voltage stabilizer, liquid replenishment pump, heat exchanger and other components, with different requirements and configuration schemes different. [0003] In the heat exchanger of the prior art mechanically sealed external circulation cooling system, a cooling water inlet nozzle and a cooling water outlet nozzle are provided on the heat exchanger tank body, and a sealing isolation liquid oil cooling device is provided in the heat exchanger tank body. Coils and baffles. The sealing isolation fluid oil is sent back to the mechanical seal chamber after heat exchange and cooling by the cooling coil in the heat exchan...

AI Technical Summary

Problems solved by technology

However, due to the poor quality of cooling water, when there are many impurities, scaling will accumulate on the sealing isolation fluid oil cooling coil in the heat exchanger, reducing the heat exchange cooling effect, causing the temperature of the sealing isolation fluid oil to rise, and affecting the safe and stable operation of the mechanical seal.
