Abstract
The utility model relates to a monitoring apparatus of primary sealing leakage in a water-cooled double mechanical seal pump, which is characterized in that the front end of a pump shaft is provided with a primary seal, an auxiliary seal is arranged in a gland cover, and the gland cover is provided with two internal thread nipples which are respectively connected with a chilled water inlet pipe and a chilled water outlet pipe. The root part of the chilled water outlet pipe is provided with a tee joint, one end of the tee joint is provided with a conductivity apparatus, the other end of the tee joint is provided with a recirculated water main pipe, and the pipeline of the recirculated water main pipe is connected with a sampling valve. The utility model has the advantages that the monitoring apparatus can immediately and accurately judge the leakage condition of the primary seal, solves the difficulty that medium flows away with chilled water and can not be found after the primary seal is leaked in the water-cooled double mechanical seal pump, avoids the pollution to the chilled water with safety and environment protection as well as energy conservation and consumption reduction, provides convenience for operation and maintenance, has simple structure and convenient operation, and is suitable for being widely popularized in process units of petroleum, chemical industry, and the like.
Description
Technical field
The utility model relates to the supervisory device that primary seal is leaked in a kind of water-cooled double mechanical seal pump.
Background technique
At present, the mechanical energy that pump plays in process units such as oil, chemical industry prime mover converts static energy and the kinetic energy that is transferred fluid to, makes to be transferred that liquid obtains to be transported to behind the energy certain pressure, height or apart from the effect of occasion.And mechanical seal is the cardiac component of pump, temperature difference according to institute's fed sheet of a media, the sealing configuration of selecting is inequality, generally when medium temperature is higher, should select double mechanical seal, the primary seal of front plays sealing institute fed sheet of a media, and auxiliary seal mainly plays the sealing cooling water.Cooling water in the existing apparatus is a circulating water, after using to a certain degree, primary seal leaks, and auxiliary seal is when still sealing, the medium that leaks will enter circulation with cooling water, and circulating water will be contaminated like this, but pump and heat exchanger are a lot of in installing, can't judge leakage point wherein, brought difficulty to Operation and maintenance, and caused waste and pollution, process units has been caused unsafe factor.
Summary of the invention
The purpose of this utility model provides the supervisory device that primary seal in a kind of water-cooled double mechanical seal pump is leaked, can not be in time when solving that primary seal is leaked in the water-cooled double mechanical seal pump, the accurate technical problem of judgement.
The technical solution of the utility model is: the supervisory device that primary seal is leaked in this water-cooled double mechanical seal pump, comprise pump shaft, sealing gland, it is characterized in that: the front end at pump shaft is equipped with primary seal, auxiliary seal is housed in sealing gland, and on sealing gland, has two internal thread interfaces to link to each other with the inlet/outlet pipe of cooling water respectively.At the cooling water outlet pipe root one threeway is arranged, an end is equipped with Conductivity Meter, and the other end removes circulating water main, and is connected to a sampling cock on its pipeline.
Cooling water is the circulating water in the process units, and primary seal is played cooling action.
Primary seal plays sealing institute fed sheet of a media, and auxiliary seal mainly plays the sealing cooling water.
The concentration and the variation of temperature of cooling water were sent alarm signal to the DCS system when Conductivity Meter leaked according to institute's fed sheet of a media.
Conductivity Meter was taken a sample with further confirmation leakage situation from sampling cock after the DCS system sends alarm signal when primary seal was leaked.
The benefit of the technical program is: can not be in time after having solved primary seal in the water cooling double mechanical seal pump and leaking, the difficult problem accurately found, and for operation, keep in repair convenience is provided.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation;
Embodiment
Referring to accompanying drawing 1, the utility model comprises axle (1), sealing gland (4), it is characterized in that: the front end at axle (1) is equipped with primary seal (2), in sealing gland (4) lining auxiliary seal (3) is housed, and two internal thread interfaces (6) are arranged on sealing gland (4), (7), respectively with the advancing of cooling water, outer pipe (5) links to each other with (8), root at cooling water outlet pipe (8) is equipped with a threeway (9), one end is equipped with Conductivity Meter (10) and goes to the DCS system, Conductivity Meter (10) is connected with threeway (9) by screw thread, and by nut (11) sealing locking, the other end goes the return main, and connects a sampling cock (12) by threeway (13) on its pipeline.
After primary seal (2) is leaked, the concentration and the temperature of the cooling water by Conductivity Meter (10) will change, and Conductivity Meter (10) will send warning to the DCS system, and then from sampling cock (12) sampling, further confirms the leakage situation of primary seal (2).
The beneficial effects of the utility model are to have solved in the water cooling double mechanical seal pump The difficult problem of can not be in time after primary seal is leaked, accurately finding is for operation, keep in repair and provide Convenient, prevented the pollution of recirculated water, safety and environmental protection, energy-saving and cost-reducing, and the structure letter Single, easy to operate, be suitable in the process units such as oil, chemical industry, extensively promoting.
Claims (1)
1, the supervisory device that primary seal is leaked in the water-cooled double mechanical seal pump, comprise pump shaft, sealing gland, it is characterized in that: the front end at pump shaft is equipped with primary seal, auxiliary seal is housed in sealing gland, and have two internal thread interfaces to link to each other with the inlet/outlet pipe of cooling water respectively on sealing gland, at the cooling water outlet pipe root one threeway is arranged, an end is equipped with Conductivity Meter, the other end removes circulating water main, and is connected to a sampling cock on its pipeline.
