Abstract

The utility model relates to a heat transfer pipe single tube thermal performance detecting device used in heat exchanger. A water pump [1], a standard pipe [9], a water flow quantifier [8] and a measured pipe [10] forms a detecting circuit after being connected in series by a water pipe [11]. The measured pipe [10] and the standard pipe [9] are positioned in a lumen [6]. Working substance is arranged in the lumen [6]. The two ends of a plurality of the measured pipes [10] and the standard pipe [9] are respectively positioned on the end plates [5] which are positioned on the two ends of the lumen [6]. The water pipe [11] and the measured pipe [10] are connected by a pipe joint. A plurality of measured pipes can be positioned in the lumen for one time. Therefore, after the measuring work of one measured pipe finished, the work of the experiment table does not need to be stopped, and the Freon does not need to be discharged. The operator only needs to simply remove the pipe joint from the measured pipe, and position the pipe joint on the next measured pipe.

Description

Be used for heat interchanger heat-transfer pipe single tube thermal property pick-up unit

Technical field

The utility model relates to a kind of heat interchanger heat-transfer pipe single tube thermal property pick-up unit that is used for.

Background technology

In the prior art, the performance that the total coefficient of heat transfer monitor station of thermoexcell can only a heat exchanger tube of one-time detection, dismounting is changed second heat pipe and is tested then.Change in the process of heat exchanger tube, must stop the work of experiment table, and the working medium in the experiment table (normally fluorine Lyons) is discharged.After wait installs, refill test working medium (fluorine Lyons) again, restart experiment table work, because will realize stable needs of experiment condition the reasonable time, required time is very long so this working routine is got off, and is difficult to satisfy the demand that factory's medium quantity batch processing product sampling is tested.Each in addition dismounting all needs to extract out fluorine Lyons wherein, also needs the experiment chamber is vacuumized, and causes the loss in fluorine Lyons, has increased experimental expenses.

Summary of the invention

The purpose of this utility model be to provide a kind of can compare experiment fast be used for heat interchanger heat-transfer pipe single tube thermal property pick-up unit.

The technical solution of the utility model is: a kind of heat interchanger heat-transfer pipe single tube thermal property pick-up unit that is used for, constitute one after being in series by water pipe by water pump, standard pipe, water flow measurement meter, a measured tube and detect the loop, described measured tube and standard pipe are arranged in the tube chamber, be marked with working medium in the tube chamber, the both ends of many measured tubes and a standard pipe are held on respectively on the end plate at tube chamber two ends, and described water pipe is connected by pipe adapter with measured tube.

The utility model compared with prior art has following advantage:

Once can in tube chamber, be provided with many measured tubes, so behind the surveying work of finishing a measured tube, need not stop the work of experiment table, more need not discharge fluorine Lyons, just simply pipe adapter is pulled down from the measured tube of having surveyed, be installed on another root measured tube and get final product, make another root measured tube be connected with water pipe.Simultaneously operating mode can be kept again, accomplish to save time, laborsaving, save experimental expenses, realize the fast whole purpose that detects.

Embodiment

Referring to accompanying drawing, the utility model both can carry out the test of the total coefficient of heat transfer under the different operating modes of individual tubes, can carry out quick contrast test again, be used for producing in batches rapidly and accurately the measurement of total coefficient of heat transfer of product, its principle of work is to test a thermoexcell each total coefficient of heat transfer under different operating modes earlier, and it is defined as standard pipe, then heat exchanger tube to be measured and standard pipe are compared test same the requirement under the operating mode, to determine the deviation size of itself and the total coefficient of heat transfer of standard pipe, again the deviation size that measures be multiply by total coefficient of heat transfer of standard pipe, can obtain total coefficient of heat transfer of tested heat exchanger tube.Be used for heat interchanger heat-transfer pipe single tube thermal property pick-up unit, by water pump [1], standard pipe [9], water flow measurement meter [8], a measured tube [10], primary heater [2], constitute one after secondary heater [7] is in series by water pipe [11] and detect the loop, described measured tube [10] and standard pipe [9] are arranged in the tube chamber [6], tube chamber is marked with working medium in [6], the both ends of many measured tubes [10] and a standard pipe [9] are held on respectively on the end plate [5] at tube chamber [6] two ends, described water pipe [11] is connected by pipe adapter with a measured tube [10], by pipe adapter, water pipe [11] can be connected with any measured tube [10].

Claims

1, a kind of heat interchanger heat-transfer pipe single tube thermal property pick-up unit that is used for, it is characterized in that: constitute one after being in series by water pipe [11] by water pump [1], standard pipe [9], water flow measurement meter [8], a measured tube [10] and detect the loop, described measured tube [10] and standard pipe [9] are arranged in the tube chamber [6], tube chamber is marked with working medium in [6], the both ends of many measured tubes [10] and a standard pipe [9] are held on respectively on the end plate [5] at tube chamber [6] two ends, and described water pipe [11] is connected by pipe adapter with measured tube [10].
