Description

机械振打器双向密封性能测试系统Mechanical Rapper Two-way Sealing Performance Test System

技术领域 technical field

本发明涉及一种机械振打器双向密封性能测试系统。 The invention relates to a two-way sealing performance testing system of a mechanical vibrator.

背景技术 Background technique

目前工业生产中，自动振打除灰装置因有效的解决了煤气化过程中气化设备换热面积灰影响传热的问题而得到了广泛推广和应用，其执行单元—机械振打器直接安装在气化设备上，其运行环境复杂，不合适的密封方式将造成严重的事故，因此，气化工艺对其密封性能的要求极其严格，需保证机械振打器在所有工况下没有至大气侧的泄漏，即外泄漏量为零，外部通入的密封保护气体通过机械振打器进气口向气化设备内泄漏量必须控制在0.5g/min以内。 In the current industrial production, the automatic rapping ash removal device has been widely promoted and applied because it effectively solves the problem that the ash in the heat exchange area of the gasification equipment affects the heat transfer in the coal gasification process. On gasification equipment, its operating environment is complex, and improper sealing methods will cause serious accidents. Therefore, the gasification process has extremely strict requirements on its sealing performance, and it is necessary to ensure that the mechanical vibrator does not reach the atmosphere under all working conditions. The leakage on the side, that is, the external leakage is zero, and the leakage of the sealing protection gas introduced from the outside into the gasification equipment through the air inlet of the mechanical vibrator must be controlled within 0.5g/min.

中国发明专利ZL 200510018677.9（机械振打器）和ZL 200910060886.X（机械振打器密封系统），采用的技术方案是：机械振打器振打执行机构设计为与设备传热面接触的撞击杆和起能量传递作用的活塞杆两个部分，外界气缸发出动能，对活塞杆产生冲击，活塞杆在冲击作用下产生微小位移，并将这个冲击传递给撞击杆，最后由撞击杆对设备传热面产生振打，避免振打执行部件出现大幅往复运动，同时引入气体保护，设置内外多重双向密封结构，能满足设备高温高压复杂工况的严格密封要求，解决了机械振打器结构及密封的实施方案，但并未涉及到对机械振打器密封性能测试的方面，而批量生产的机械振打器在实际应用前需模拟实际工况进行全面的密封性能测试。目前并未见关于高温高压工况下机械振打器及类似密封结构性能测试系统技术方面的报道，且普通条件下，室温的气态介质加热至煤气化工艺要求的温度需要时间较长，影响实际测试效率，无法满足批量生产机械振打器的全面测试要求；同时，由于机械振打器振打执行机构本身为传动连接，在一定内外压差的作用下较易与活塞导筒脱离，测试时容易对产品造成损坏。 Chinese invention patents ZL 200510018677.9 (mechanical vibrator) and ZL 200910060886.X (mechanical vibrator sealing system), the technical solution adopted is: the mechanical vibrator vibration actuator is designed as an impact rod in contact with the heat transfer surface of the equipment And the two parts of the piston rod that play the role of energy transfer. The external cylinder emits kinetic energy, which produces an impact on the piston rod. The rapping surface is generated to avoid large-scale reciprocating movement of the rapping actuator. At the same time, gas protection is introduced, and multiple bidirectional sealing structures are set inside and outside, which can meet the strict sealing requirements of high-temperature and high-pressure complex working conditions of the equipment, and solve the problem of mechanical rapper structure and sealing. Implementation plan, but it does not involve the aspect of testing the sealing performance of mechanical rappers, and the mechanical rappers produced in batches need to simulate the actual working conditions for a comprehensive sealing performance test before actual application. At present, there are no reports on mechanical vibrator and similar sealing structure performance test system technology under high temperature and high pressure conditions, and under normal conditions, it takes a long time for the gaseous medium at room temperature to be heated to the temperature required by the coal gasification process, which affects the actual The test efficiency cannot meet the comprehensive test requirements of mass-produced mechanical rappers; at the same time, since the rapping actuator itself of the mechanical rapper is connected by transmission, it is easier to separate from the piston guide cylinder under the action of a certain internal and external pressure difference. It is easy to cause damage to the product.

一并参照图1-图3，其中图3可视为揭示一种密封性能测试方法，此密封测试方法包含下列步骤： Referring to Fig. 1-Fig. 3 together, wherein Fig. 3 can be regarded as revealing a kind of sealing performance test method, and this sealing test method comprises the following steps:

1)        开启阀门I2，关闭其他阀门，打开空气压缩机1，待缓冲罐4内压力增加至0.5MPa后，打开阀门II5，将上次试验的缓冲罐4内所沉积的水分、污垢等通过管路3排净至缓冲罐外（步骤31）； 1) Open valve I2, close other valves, and turn on air compressor 1. After the pressure in the buffer tank 4 increases to 0.5MPa, open valve II5, and pass the moisture and dirt deposited in the buffer tank 4 in the previous test through the pipe. road 3 drain to the outside of the buffer tank (step 31);

2)        将被测机械振打器凸面法兰27通过螺栓垫片安装在试验筒体凸面法兰28上，将金属软管17与被测机械振打器进气口26连接，将外漏检测装置22的气体导向端盖23安装在被测机械振打器活塞导筒21端部（步骤32）； 2) Install the convex flange 27 of the tested mechanical vibrator on the convex flange 28 of the test cylinder through bolts and gaskets, connect the metal hose 17 to the air inlet 26 of the tested mechanical vibrator, and detect the external leakage The gas guide end cover 23 of the device 22 is installed on the end of the piston guide cylinder 21 of the mechanical rapper under test (step 32);

3)        开启阀门I2、阀门

Figure 615583DEST_PATH_IMAGE003
9、阀门10，关闭其他阀门，开启空气压缩机1、缓冲罐4及试验筒体11上的电加热器，使得缓冲罐及试验筒体内气体压力及温度提升至预定压力及温度（步骤33），所述的预定压力范围为：3.5MPa~4.0MPa，预定温度为：250℃~270℃； 3) Open valve I2, valve
Figure 615583DEST_PATH_IMAGE003
9. Valve 10. Close other valves, turn on the electric heater on the air compressor 1, the buffer tank 4 and the test cylinder 11, so that the gas pressure and temperature in the buffer tank and the test cylinder are raised to the predetermined pressure and temperature (step 33), the The predetermined pressure range is: 3.5MPa~4.0MPa, and the predetermined temperature is: 250℃~270℃;

4)        通过试验筒体11上压力传感器及温度传感器监测试验筒体11内压力及温度，待达到预定要求后，保温保压5min（步骤34）； 4) Monitor the pressure and temperature inside the test cylinder 11 through the pressure sensor and temperature sensor on the test cylinder 11, and keep the heat and pressure for 5 minutes after reaching the predetermined requirements (step 34);

5)        观察并记录步骤34中水箱25内冒气泡情况，若水箱中有连续冒泡现象产生，即该被测机械振打器20外密封存在缺陷，为不合格产品；若水箱25中无连续冒泡现象产生，即被测机械振打器20向外部大气无泄露（步骤35）； 5) Observe and record the bubbling in the water tank 25 in step 34. If there is continuous bubbling in the water tank, it means that the outer seal of the tested mechanical vibrator 20 is defective, and it is a substandard product; if there is no continuous bubbling in the water tank 25. The bubbling phenomenon occurs, that is, the tested mechanical rapper 20 has no leakage to the external atmosphere (step 35);

6)        进一步对被测机械振打器26进行内部密封性能测试：开启阀门2、阀门10，关闭其他阀门，保持试验筒体11内温度及压力不变，开启空气压缩机1，待缓冲罐7内空气压力及温度提升至预定提升值后，保温保压预定时间30min；具体的说，步骤36实际上是通过提高缓冲罐4内压力来提升管路IV14及被测机械振打器进气口26内空气的压力，该预定提升值为0.5MPa~0.6MPa，即管路IV14内空气压力较试验筒体21内压力要高0.5MPa~0.6MPa，同时，通过电加热器来防止缓冲罐4及试验筒体11内温度的下降（步骤36，37）； 6) Further test the internal sealing performance of the tested mechanical rapper 26: open the valve 2. Valve 10. Close other valves, keep the temperature and pressure in the test cylinder 11 constant, turn on the air compressor 1, and wait for the air pressure and temperature in the buffer tank 7 to rise to the predetermined value, and keep the heat for a predetermined time of 30 minutes; specifically , step 36 actually increases the pressure of the air in the pipeline IV14 and the air inlet 26 of the tested mechanical vibrator by increasing the pressure in the buffer tank 4. The air pressure is 0.5MPa~0.6MPa higher than the pressure inside the test cylinder 21, and at the same time, the electric heater is used to prevent the temperature drop in the buffer tank 4 and the test cylinder 11 (steps 36, 37);

7)        观察并记录步骤37中管路IV14上微量流量计13示值的变化情况，具体的说，微量流量计13的示值即表示气体介质在管路IV14内的流动情况，预定压差作用下，管路

Figure 550949DEST_PATH_IMAGE004
14内气体将通过被测机械振打器20内部结构往试验筒体11内流动，微量流量计13的示值即为被测机械振打器20通过其进气口26往试验筒体11内泄漏量的大小；同时，观察并记录步骤37过程中水箱25中气泡的情况（步骤38）； 7) Observe and record the changes in the indication value of the micro flowmeter 13 on the pipeline IV14 in step 37. Specifically, the indication value of the micro flowmeter 13 indicates the flow of the gas medium in the pipeline IV14, and the predetermined pressure difference effect down, pipeline
Figure 550949DEST_PATH_IMAGE004
The gas in 14 will flow into the test cylinder 11 through the internal structure of the mechanical rapper 20 under test, and the indication value of the micro flow meter 13 is that the mechanical rapper 20 under test flows into the test cylinder 11 through its air inlet 26 The size of the leakage; meanwhile, observe and record the situation of air bubbles in the water tank 25 in the step 37 process (step 38);

8)        若步骤38中微量流量计13最大示值大于0.5g/min，表明该台被测机械振打器20存在内密封泄漏的缺陷，为不合格产品；若小于等于0.5g/min，依此判断被测机械振打器进气口26向试验筒体11内部泄露情况符合技术要求，即内密封合格；同时，若步骤38中水箱25内无连续冒泡现象产生，则该台被测机械振打器20外密封符合要求；若该被测机械振打器20内外密封均合格，可判断该被测机械振打器20密封性能合格（步骤39，40）； 8) If the maximum indication value of the micro flowmeter 13 in step 38 is greater than 0.5g/min, it indicates that the mechanical vibrator 20 under test has a defect of inner seal leakage, and it is an unqualified product; if it is less than or equal to 0.5g/min, follow It is judged that the leakage of the air inlet 26 of the tested mechanical rapper to the inside of the test cylinder 11 meets the technical requirements, that is, the internal seal is qualified; at the same time, if there is no continuous bubbling phenomenon in the water tank 25 in step 38, then the tested machine The outer seal of the mechanical rapper 20 meets the requirements; if the inner and outer seals of the tested mechanical rapper 20 are qualified, it can be judged that the tested mechanical rapper 20 has a qualified sealing performance (steps 39 and 40);

9)        完成内外密封性能测试后，关闭其他所有阀门，开启阀门V16，使得试验筒体11内气压通过管路V15与管路

Figure 977382DEST_PATH_IMAGE004
14内气压达到平衡，再缓慢开启阀门
Figure 979974DEST_PATH_IMAGE006
19，使得试验筒体11及管路IV14内气体同时通过管路18排至外界大气，避免泄压时步骤36因试验筒体与被测机械振打器进气口间所产生的压力差对被测机械振打器20造成的损坏；具体的说，若试验筒体11与被测机械振打器进气口26的泄压不同步，被测机械振打器20的振打执行机构—被测机械振打器活塞杆29、被测机械振打器撞击杆30则会在此压差的作用下与被测机械振打器活塞导筒21脱离，造成被测机械振打器20的损坏，因此管路V15可实现对被测机械振打器20进行非破坏性密封测试（步骤41）； 9) After completing the internal and external sealing performance test, close all other valves and open valve V16, so that the air pressure in the test cylinder 11 passes through the pipeline V15 and the pipeline
Figure 977382DEST_PATH_IMAGE004
14 When the internal air pressure reaches equilibrium, then slowly open the valve
Figure 979974DEST_PATH_IMAGE006
19, so that the gas in the test cylinder 11 and the pipeline IV14 passes through the pipeline at the same time 18 is exhausted to the outside atmosphere to avoid damage to the tested mechanical vibrator 20 caused by the pressure difference between the test cylinder and the air inlet of the tested mechanical vibrator in step 36 during pressure relief; specifically, if the test The cylinder body 11 is not synchronized with the pressure relief of the air inlet 26 of the mechanical rapper under test, and the rapping actuator of the mechanical rapper 20 under test—piston rod 29 of the mechanical rapper under test and the mechanical rapper under test hit The rod 30 will be separated from the piston guide cylinder 21 of the mechanical rapper under test under the action of this pressure difference, causing damage to the mechanical rapper 20 under test, so the pipeline V15 can realize the mechanical rapper 20 under test. Non-destructive seal test (step 41);

待试验筒体11、管路IV14完成泄压后，拆卸完成试验的机械振打器20，安装好下一台被测机械振打器；缓慢开启阀门I2、阀门III9、阀门IV10，关闭其他阀门，重复步骤32~42；具体的说，本发明引入了平衡支路—管路V15，使得步骤41中不通过缓冲罐4向外泄压时也能保证试验筒体与被测机械振打器进气口26的同步泄压，步骤41中泄压时切断了缓冲罐4内气体与外界的流通，使得缓冲罐4内已达到预定要求压力及温度的气体得到保留，重复步骤32时可避免再次重复长时间加温加压的过程，有效的节省试验成本及试验时间，提高试验效率（步骤42）。 After the pressure relief of the test cylinder 11 and the pipeline IV14 is completed, disassemble the mechanical vibrator 20 that has been tested, and install the next mechanical vibrator to be tested; slowly open the valve I2, valve III9, and valve IV10, and close other valves , repeating steps 32 to 42; specifically, the present invention introduces a balance branch—pipeline V15, so that the test cylinder and the mechanical rapper under test can be guaranteed when the pressure is not released through the buffer tank 4 in step 41. The synchronous pressure relief of the air inlet 26 cuts off the circulation of the gas in the buffer tank 4 and the outside world during the pressure relief in step 41, so that the gas that has reached the predetermined required pressure and temperature in the buffer tank 4 is retained, and can be avoided when repeating step 32. The process of heating and pressurizing for a long time is repeated again, effectively saving test cost and test time, and improving test efficiency (step 42).
