Abstract
The present invention relates to the long range blowing method of specifically a kind of sled sled racing track ammonia refrigeration pipeline；It is characterized in that: including selection compressed air unit, individual volume is prepared greater than 2m3 air accumulator, determines pipeline inlet end and discharge end；Since sled sled racing track refrigeration piping entirety absolute altitude is characterized in a kind of arrangement from high in the end, in the selection of inlet end and discharge end aloft inlet end setting, discharge end is arranged in lower, is conducive to the discharge of dirt in this way；A whole set of purge system is connect with pipeline inlet end；It opens air-pressure equipment constantly to pressurize in closed system, purge out；Pipeline inner wall is checked using high definition pipe monitoring device, examines purging quality.This cleaning method utilizes the difference of height advantage of pipeline oneself height, it is equipped with the pipeline strong to environment-adapting ability, it is aided with large capacity gas source and pressure and video monitoring system again, the pipeline of Large Diameter Pipeline, long range is cleaned back and forth, to realizes quickly and effectively pipeline purging means.
Description
Technical field
The present invention relates to pipeline construction field, the long range purging side of specifically a kind of sled sled racing track ammonia refrigeration pipeline
Method.
Background technique
The overall length of sled sled racing track refrigeration supervisor is up to 5090 meters, maximum caliber 457.2mm.Since pipeline is long, and manage
Line internal request cleannes are very high.The spy that such caliber is big in this way, traditional the methods of pressure wash is not applied for, pipeline is long
Different pipeline, thus, effective method is lacked at present for the cleaning of such pipeline.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, provide a kind of suitable for major diameter, the high cleaning of long-distance pipe
Spend cleaning method.
In order to achieve the above object, the present invention is implemented as follows:
A kind of long range blowing method of sled sled racing track ammonia refrigeration pipeline, including
Step 1, selection compressed air unit, it is desirable that the equipment carries drying, filtration system, and capacity is big, specified maximum exhaust
Pressure is greater than 1MPa.Air-pressure equipment overall dimension is small, is readily transported and has bad luck；
Step 2 prepares individual volume greater than 2m3 air accumulator, and effect is the more compressed airs of reserve, increases single compressed air
The time of blow line；
Step 3 determines pipeline inlet end and discharge end.Due to sled sled racing track refrigeration piping entirety absolute altitude be characterized in it is a kind of from
High arrangement on earth, in the selection of inlet end and discharge end aloft inlet end setting, discharge end are arranged in lower,
Be conducive to the discharge of dirt in this way；
Step 4 connects air-pressure equipment, air accumulator, is arranged in the gas outlet of air accumulator for the valve of opening and closing and one piece in school
Test the pressure gauge in the phase, the connection of air accumulator and pipeline is connected using high-pressure hose, the length of hose guarantee 20m ~ 30m it
Between, selection can both reduce the configuration amount of interim pipeline using such hose, also facilitate the environment for being applicable in various landform；
A whole set of purge system is connect by step 5 with pipeline inlet end, and high pressure inflated rubber leather bag is arranged in discharge end pipeline
It blocks, pipeline is formed into a confined space；
Step 6, unlatching air-pressure equipment constantly pressurize in closed system, guarantee that system pressure is not less than 0.8MPa, discharge
End rubbery human body is purged out by moment, drives the dirt discharge line in pipeline；
Step 7 repeats to clean step 4 ~ 5 time and checks pipeline inner wall using high definition pipe monitoring device, purging quality is examined, if not
Qualification repeats to purge work.
This cleaning method is equipped with using the difference of height advantage of pipeline oneself height to environment-adapting ability using above-mentioned design
Strong pipeline, then be aided with large capacity gas source and pressure and video monitoring system, back and forth to the pipeline of Large Diameter Pipeline, long range into
Row cleans, to realize high cleanliness, quickly and effectively pipeline purging means.
Detailed description of the invention
Fig. 1: the purging main component and type of attachment of equipment.
Fig. 2: setting main points, the method for entire purge system connect the signal of completion.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of long range blowing method of sled sled racing track ammonia refrigeration pipeline, including
Step 1, selection compressed air unit, it is desirable that the equipment carries drying, filtration system, and capacity is big, specified maximum exhaust
Pressure is greater than 1MPa.Air-pressure equipment overall dimension is small, is readily transported and has bad luck；
Step 2 prepares individual volume greater than 2m3 air accumulator, and effect is the more compressed airs of reserve, increases single compressed air
The time of blow line；
Step 3 determines pipeline inlet end and discharge end.Due to sled sled racing track refrigeration piping entirety absolute altitude be characterized in it is a kind of from
High arrangement on earth, in the selection of inlet end and discharge end aloft inlet end setting, discharge end are arranged in lower,
Be conducive to the discharge of dirt in this way；
Step 4 connects air-pressure equipment, air accumulator, is arranged in the gas outlet of air accumulator for the valve of opening and closing and one piece in school
Test the pressure gauge in the phase, the connection of air accumulator and pipeline is connected using high-pressure hose, the length of hose guarantee 20m ~ 30m it
Between, selection can both reduce the configuration amount of interim pipeline using such hose, also facilitate the environment for being applicable in various landform；
A whole set of purge system is connect by step 5 with pipeline inlet end, and high pressure inflated rubber leather bag is arranged in discharge end pipeline
It blocks, pipeline is formed into a confined space；
Step 6, unlatching air-pressure equipment constantly pressurize in closed system, guarantee that system pressure is not less than 0.8MPa, discharge
End rubbery human body is purged out by moment, drives the dirt discharge line in pipeline；
Step 7 repeats to clean step 4 ~ 5 time and checks pipeline inner wall using high definition pipe monitoring device, purging quality is examined, if not
Qualification repeats to purge work.
This cleaning method is equipped with using the difference of height advantage of pipeline oneself height to environment-adapting ability using above-mentioned design
Strong pipeline, then be aided with large capacity gas source and pressure and video monitoring system, back and forth to the pipeline of Large Diameter Pipeline, long range into
Row cleans, to realize high cleanliness, quickly and effectively pipeline purging means.
