The utility model is mainly made up of rubbing device and water repellency test device two parts, and rubbing device simulation rope makes
Influenceed during by rubbing, water repellency test device carries out water repellency test to test rope, and record test rope absorbs water
The content divided, so as to calculate the water absorption rate of test rope, to characterize the water repellency of rope, so as to the water repellent finish to rope
Effect has the evaluation of an objective, and two parts apparatus structure is simple, and cost is cheap, and Installation And Test is simple to operate, uses
It is convenient, the testing efficiency of rope is improved, human cost is saved, disclosure satisfy that the water repellency of the following fibrecords of diameter 14mm
Test, has filled up the blank of this performance test apparatus of domestic field of rope and method.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the profile of friction passage；
Fig. 3 is the structural representation of fixed plate 31 and portable plate 32.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings：
As Figure 1-3, a kind of rope water repellency tester, includes rubbing device and test device two parts group
Into the rubbing device includes base 1, friction passage 3 and heavy burden counterweight 2, and the friction passage 3 is fixedly installed on base 1
On, the outside of friction passage 3 sets four fixed plates 31 and three portable plates 32, and folder is formed between four fixed plates 31
Angle is 120 ° of three cracks, and three portable plates 32 are radially disposed in three cracks, and can be locked, described three
Portable plate 32 when being locked the friction passage 3 be not subject to external force, when test rope carries out friction treatment, in three portable plates
Heavy burden counterweight 2 is fixedly installed in 32 position respectively, applies pressure to the test rope Jing Guo friction passage 3；The test device
Include testing base 4, water pump 5 and flow cavitation result panel 6, the flow cavitation result panel 6 and water pump 5 are fixedly installed on test bottom
On seat 4, the flow cavitation result panel 6 is 30 ° with the plane included angle of testing base 4, and fixation is provided with the flow cavitation result panel 6
Groove 7, rope is tested for fixed, the outlet pipe of the water pump 5 is connected groove 7.
The weight of heavy burden counterweight 2 of the rubbing device is arranged to 5Kg.
The internal diameter of friction passage 3 of the rubbing device is 10-13mm, and length is arranged to 50mm-90mm.
Water velocity is 1-3L/min in the flow cavitation result panel 6 of the test device.
A kind of method of testing of rope water repellency tester, is achieved by the steps of：
1）Friction treatment：Test rope is taken, a mark is done respectively at test rope ends distance 20-30cm, will survey
