Description
Technical field
The present invention, about sack cleaner and accessory thereof, particularly relates to a kind of method of testing weighing filter bag packing elasticity quality.
Background technology
Packing, as the key fitment of filter bag, plays the effect of fixing filter bag in actual use.The quality of packing quality directly affects the use of filter bag.Domestic still not for the method for testing that packing elasticity is good and bad at present, the producer that market produces packing is many, and quality is uneven.The phenomenons such as packing poor flexibility, fracture, rivet come off often occur in actual use, causes the accidents such as filter bag head leakage ash, entirety come off, have a strong impact on the overall performance of sack cleaner.
Summary of the invention
It is an object of the invention to provide a kind of method of testing weighing packing elasticity quality, to check packing can meet actually used prescription.
For achieving the above object, the solution of the present invention is:
A kind of method of testing weighing packing elasticity quality, it specifically includes following steps:
Step 1, whether jagged observing packing surface, if smooth, smooth, measure the width average deviation on the diverse location of packing less than or equal to 5% with ruler, thickness average deviation is as the criterion less than or equal to 10%；
Step 2, on packing, carry out labelling as test point, and measured the green diameter of packing by ruler, record green diameter numerical value D1；
Step 3, by extrusion equipment, packing being compressed, compression distance is the 80% ~ 85% of green diameter, and reciprocation cycle 5 ~ 10 times, observes whether packing connecting portion in test process comes off or rupture, judges that this packing is defective if it occur that come off or rupture；
When packing remains intact in step 4, test process, measure and record packing diameter value D2 after test point position is compressed with ruler, obtain the size conservation rate of packing by calculating D2/D1, when conservation rate is more than 85%, can determine that this steel ring is qualified；
Step 5, this test randomly select sample, at least do the replica test of 3 groups, and result of the test average deviation is less than or equal to 2%, and the elastic quality of packing can be made the judgement of acceptance or rejection.
The material of described packing is carbon steel or stainless steel.
The specification of described packing is the diameter packing more than 50mm.
After adopting such scheme, the present invention adopts 2 equidistant compression verifications packing size conservation rate after several times compress, namely by testing packing under being subject to External Force Acting, after deforming upon, the reciprocal compression whether packing can bear, and can packing recover preferably after external force is cancelled, differentiate that whether packing elasticity is qualified with this.
Detailed description of the invention
Present invention is disclosed a kind of method of testing weighing packing elasticity quality, it specifically includes following steps:
Whether jagged step 1, range estimation, observe packing surface, if smooth, smooth；Measuring the width average deviation on the diverse location of packing less than or equal to 5% with ruler, thickness average deviation is as the criterion less than or equal to 10%；
Step 2, on packing, carry out labelling as test point, and measured the green diameter of packing by ruler, record green diameter numerical value D1；
Step 3, by extrusion equipment to the packing certain distance of compression, compression distance is that 80% ~ 85%(of green diameter distance compressed is determined by packing material and specification), and reciprocation cycle 5 ~ 10 times (compression number of times is determined by packing material and specification), observe whether packing connecting portion (rivet location) in test process comes off or rupture, judge that this packing is defective if it occur that come off or rupture；
When packing remains intact in step 4, test process, measure and record packing diameter value D after test point position is compressed with ruler2, by calculating D2/D1Obtain the size conservation rate of packing, when conservation rate is more than 85%, can determine that this steel ring is qualified；
Step 5, this test randomly select sample, at least do the replica test of 3 groups, and result of the test average deviation is less than or equal to 2%, and the elastic quality of packing can be made the judgement of acceptance or rejection.
Below in conjunction with specific embodiment, the present invention is expanded on further.
Embodiment 1
Being the packing of 130mm by diameter, while confirming material and specification, whether observation packing outward appearance is smooth, smooth, impulse-free robustness, packing is fixed on test instrunment, fixture in adjustment, controls fixture and just contacts (with hands weak vibrations packing, there is slight resistance) with packing.Diameter D is measured with ruler1, and the good upper and lower test point of labelling.By packing is compressed until upper and lower two test points are at a distance of 20mm, reciprocating compression 5 times, observe packing outward appearance deformation situation, again measure diameter D with ruler2, calculate the conservation rate of packing.
Embodiment 2
Being the packing of 160mm by diameter, while confirming material and specification, whether observation packing outward appearance is smooth, smooth, impulse-free robustness, packing is fixed on test instrunment, fixture in adjustment, controls fixture and just contacts (with hands weak vibrations packing, there is slight resistance) with packing.Diameter D is measured with ruler1, and the good upper and lower test point of labelling.By packing is compressed until upper and lower two test points are at a distance of 30mm, reciprocating compression 8 times, observe packing outward appearance deformation situation, again measure diameter D with ruler2, calculate the conservation rate of packing.
Test result:
Table 1. packing test result
| Sequence number | Green diameter D1(mm) | Packing diameter D after compression2(mm) | Deformation quantity (mm) | Conservation rate=D2/D1(%) |
| 1 | 158.8 | 144.0 | 14.8 | 90.68 |
| 2 | 158.0 | 144.7 | 13.3 | 91.58 |
| 3 | 158.5 | 144.2 | 14.3 | 90.98 |
In sum, the method for testing of a kind of packing of the present invention, it is preferred that emphasis is test packing is under being subject to External Force Acting, after deforming upon；The reciprocal compression whether packing can bear, and after external force is cancelled, can packing recover preferably, differentiates that whether packing elasticity is qualified with this.In case study on implementation 1, elastic piston ring ruptures near link position, can illustrate that packing is defective；In case study on implementation 2 and shown in table 1, packing to be measured profile after test keeps good, and conservation rate both is greater than 85%, and test has repeatability and can be determined that packing is elastic good.
