Abstract
A large-diameter multifunctional flow path sealing test apparatus is characterized by comprising a tester main body, a high-speed elastic membrane coupling, a spiral sensor, a speed increaser, a main motor and a platform. The tester main body is connected with the spiral sensor through the high-speed elastic membrane coupling; the spiral sensor is connected with the main motor through the speed increaser; and the main motor is arranged on the platform. According to the utility model, the advantages are provided as following: the large-diameter multifunctional flow path sealing test apparatus can satisfy the sealing test of a flow path with the largest diameter of 1000 mm, and the problems of sealing test and development of a large-diameter flow path are solved. The present problem that no tester is provided for verifying the large-diameter brush type sealing technology on an engine, the passive condition that the brush type sealing technology only stays on the theory research base is prevented, the development of the brush type sealing technology is greatly promoted, and application is wide.
Description
Technical field
The utility model relates to the test unit field of engine stream sealing, particularly the multi-functional stream seal test device of a kind of major diameter.
Background technology
On engine and combustion machine, widely apply the stream sealing.But before stream is sealed in and is applied on combustion machine or the engine, must could guarantee its security and reliability through lot of test accumulation and research at engine run.So the brush seal exerciser is a restriction various types brush seal development key; The at present domestic brush seal exerciser that does not still have specialty; The major diameter brush seal test that particularly adapts to the engine development still can't make an experiment so far; Can only rest on the theoretical research basis, the development along with the brush seal specialty presses for large diameter professional brush seal exerciser very much.This device can satisfy the stream leakage test of maximum gauge 1000mm, has solved the test and the development problem of major diameter stream sealing fully.
The utility model content
The purpose of the utility model is in order to satisfy the stream leakage test of maximum gauge 1000mm, and the spy provides a kind of major diameter multi-functional stream seal test device.
The utility model provides a kind of major diameter multi-functional stream seal test device, it is characterized in that: the multi-functional stream seal test device of described major diameter comprises exerciser main body 2; High speed flexible sheet shaft coupling 3, twist counter 4, speed-increasing gear 5; Main motor 6, platform 7;
Wherein: exerciser main body 2 is connected with twist counter 4 through high speed flexible sheet shaft coupling 3, and twist counter 4 is connected with main motor 6 through speed-increasing gear 5, and main motor 6 is installed on the platform 7.
Described exerciser main body 2 is upper and lower minute body structure.
Testpieces 1 is a cantilever design, and the mounting or dismounting of testpieces 1 are convenient, and the process of the test testpieces decomposes easily; The exerciser main body can be motionless, and main bearing is selected the reliable high-performance bearing of using on the engine for use, and packoff is employed in the circumference graphite grazing device of using on the engine; Draw supercharging gas, engine sealing technology is ripe, this pattern good seal performance; And by the front fulcrum packoff with keeping apart between exerciser and the testpieces; Effective protection test device, the reliability of raising exerciser, means of testing is many and reliable.A kind of means are directly to measure the gas flow that brush seal leaks through the sealing drain charge chamber in exerciser main body left side; And be convenient to observe the duty of brush type sealed track and brush seal; As brush the friction work distortion of silk and carry out infrared thermography; Another kind of means are through both sides brush seal leakage rate, and error is arranged, and half that equals to test total charge flow rate estimated; Improving the security consideration of exerciser main body, mainly is brush seal test section part, and we leak cavity pressure through test macro monitoring two; When reaching certain pressure; In the time of possibly producing bigger axial force, test macro possesses warning device, can cut off source of the gas simultaneously.
The advantage of the utility model:
The multi-functional stream seal test device of the described major diameter of the utility model can satisfy the stream leakage test of maximum gauge 1000mm, has solved the test and the development problem of major diameter stream sealing fully.Solved the present situation of the no exerciser checking of major diameter brush seal technology on the engine, avoided the brush seal technology only to rest on the passive situation on the theoretical research basis, promoted the development of brush seal specialty greatly, be widely used.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the multi-functional stream seal test device of major diameter.
Embodiment
Embodiment 1
The utility model provides a kind of major diameter multi-functional stream seal test device, it is characterized in that: the multi-functional stream seal test device of described major diameter comprises exerciser main body 2; High speed flexible sheet shaft coupling 3, twist counter 4, speed-increasing gear 5; Main motor 6, platform 7;
Wherein: exerciser main body 2 is connected with twist counter 4 through high speed flexible sheet shaft coupling 3, and twist counter 4 is connected with main motor 6 through speed-increasing gear 5, and main motor 6 is installed on the platform 7.
Described exerciser main body 2 is upper and lower minute body structure.
Testpieces 1 is a cantilever design, and the mounting or dismounting of testpieces 1 are convenient, and the process of the test testpieces decomposes easily; The exerciser main body can be motionless, and main bearing is selected the reliable high-performance bearing of using on the engine for use, and packoff is employed in the circumference graphite grazing device of using on the engine; Draw supercharging gas, engine sealing technology is ripe, this pattern good seal performance; And by the front fulcrum packoff with keeping apart between exerciser and the testpieces; Effective protection test device, the reliability of raising exerciser, means of testing is many and reliable.A kind of means are directly to measure the gas flow that brush seal leaks through the sealing drain charge chamber in exerciser main body left side; And be convenient to observe the duty of brush type sealed track and brush seal; As brush the friction work distortion of silk and carry out infrared thermography; Another kind of means are through both sides brush seal leakage rate, and error is arranged, and half that equals to test total charge flow rate estimated; Improving the security consideration of exerciser main body, mainly is brush seal test section part, and we leak cavity pressure through test macro monitoring two; When reaching certain pressure; In the time of possibly producing bigger axial force, test macro possesses warning device, can cut off source of the gas simultaneously.
