Description

Technical Field

[0001] The utility model relates to the technical field of equipment oil sample collection, in particular to an anti-pollution oil particle contamination sampling umbrella cover. Background Art

[0002] With the commissioning and use of large-capacity and high-parameter units in thermal power plants, the requirements for the working reliability and service life of mechanical equipment are getting higher and higher. A large number of actual production surveys have found that solid particle contaminants in the oil are the main cause of abrasive wear of mechanical equipment. Oil contamination not only leads to the deterioration of the performance of machinery and lubricants, reduces the service life of mechanical equipment and oil, but also puts the equipment in a dangerous state. Therefore, controlling the size and number of contaminant particles in the oil has a significant effect on controlling the wear of parts, avoiding the occurrence of wear failures, and improving the working reliability of equipment and extending the service life of equipment. Therefore, the equipment lubricating oil is regularly tested to detect the size and number of particles in the oil.

[0003] The existing method of sampling lubricating oil from equipment is to directly install the oil pipe at the oil inlet of the equipment. However, due to the harsh environment of the production site, especially the unit maintenance site, there is visible or invisible dust in the air, which will cause secondary contamination to the oil during the oil collection process, making the test results unable to reflect the true cleanliness of the oil. In view of this, an anti-pollution oil particle contamination sampling cover is designed. Summary of the invention

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] Provided is an anti-pollution oil particle contamination sampling umbrella cover, comprising a tubular sampling valve joint, a transparent umbrella cover is arranged on the periphery of the tubular sampling valve joint, the umbrella cover can be folded or unfolded, a transparent ring curtain is arranged around the umbrella cover, a three-way valve is installed at the bottom of the sampling valve joint, a sampling tube for discharging test oil samples is arranged at the first outlet of the three-way valve, a dust plug is arranged at the sampling port of the sampling tube, an oil discharge branch pipe is arranged at the second outlet of the three-way valve, and the outlet end of the oil discharge branch pipe can extend outside the ring curtain.

[0006] Preferably, the ring curtain and the umbrella cover are detachably connected via a zipper, Velcro or snaps.

[0007] Preferably, the ring curtain is provided with a hand hole.

[0008] Preferably, a pocket is provided at the edge where the umbrella cover and the ring curtain are connected, and the folded ring curtain can be placed therein.

[0009] Preferably, the three-way valve is an electrically controlled valve, and the control end can extend to the outside of the umbrella cover.

[0010] The beneficial effects of the utility model are: an enclosed space can be formed by setting the umbrella cover and the surrounding transparent curtain on the base surface, which can isolate the on-site sampling environment, thereby preventing the pollutants in the environment from contaminating the sampling equipment, thereby preventing the oil from being contaminated by secondary pollution. It is ensured that the oil sample taken truly reflects the state of the oil in the equipment, and the accuracy of oil particle size measurement is improved. In addition, the main body of the equipment is simple to use and easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] In the figure: 1-sampling valve connector, 2-umbrella cover, 3-ring curtain, 4-three-way valve, 5-sampling tube, 6-oil drain branch pipe, 7-dust plug. DETAILED DESCRIPTION

[0014] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model rather than to limit the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0015] In a specific embodiment, an anti-pollution oil particle contamination sampling umbrella cover is provided, including a tubular sampling valve connector 1, a transparent umbrella cover 2 is arranged around the tubular sampling valve connector 1, and the umbrella cover 2 can be folded or unfolded in the same manner as the existing umbrella opening and closing structure. In addition, a transparent ring curtain 3 is arranged around the umbrella cover 2, which can form a complete isolated sampling space with the umbrella cover 2, thereby effectively preventing dust particles and other debris in the working environment from entering the sampled oil and affecting the detection accuracy during the sampling process. In addition, a three-way valve 4 is installed at the bottom of the sampling valve connector 1, wherein the first outlet of the three-way valve 4 is provided with a sampling tube 5 for discharging the detection oil sample, the first outlet of the three-way valve 5 is provided with a dust plug 7, and the second outlet of the three-way valve 4 is provided with an oil discharge branch pipe 6, the outlet end of the oil discharge branch pipe 6 can extend outside the ring curtain 3, and the oil discharge branch pipe 6 is used to discharge the contaminated oil in the initial section of each pipeline before sampling, and the oil discharge passage can be switched in time according to the situation by switching the three-way valve, thereby improving the sampling efficiency.

[0016] During the sampling operation, first open the umbrella cover 2, drop the ring curtain 3 to overlap the installation base (ground or equipment surface) to form a closed space. Connect the sampling valve joint 1 to the oil outlet of the equipment, rotate the three-way valve 4 to connect the sampling valve joint 1 to the oil drain branch pipe 6, repeatedly open and close the sampling valve joint 1 3 to 5 times to drain the dead oil in the equipment, and also flush the sampling valve joint 1. It should be noted that since there is no oil in the sampling tube 5 after sampling, flushing is usually not required. Flushing is also required when the accuracy requirement is high. In order to prevent dust from entering the sampling tube 5, a dust plug 7 is provided at the outlet of the sampling tube 5, and the dust plug 7 is usually removed before sampling. Align the mouth of the sampling bottle with the mouth of the sampling tube 5, rotate the three-way valve 4 until the sampling valve connector 1 is connected to the sampling tube 5 without changing the liquid flow through the sampling valve, and sample 200 mL; then remove the sampling bottle and cover the bottle cap in the umbrella cover, then close the pipeline valve in sequence, install the dust plug, and put away the umbrella cover. In order to facilitate the above operation and avoid repeated lifting of the circle curtain 3, a hand hole is provided at the side end of the circle curtain 3, and the operation can be carried out through the hand hole, but it should be noted that a curtain is also provided at the hand hole, and the hand falls when the hand is not entered, which effectively avoids the disadvantage of the circle curtain 3 being lifted up significantly. Similarly, for the convenience of operation, the three-way valve 5 is an electrically controlled valve, and the control end can extend to the outside of the umbrella cover 2, and the operator can control it from the outside through the switch.

[0017] By comparing the use of umbrella cover and the non-umbrella cover, oil sample 1 uses an umbrella cover, and oil sample 2 does not use an umbrella cover. After analyzing the oil particle contamination in the laboratory, oil sample 1 showed a particle contamination level of SAE AS4059 5, and oil sample 2 showed a particle contamination level of SAE AS4059 8, indicating that oil sample 2 is seriously contaminated by environmental dust and the number of large particles has increased significantly, indicating that the anti-pollution oil particle contamination sampling umbrella cover can effectively avoid secondary contamination of the oil and can represent the true state of the oil in the equipment.

[0018] Particle size (pieces / 100mL oil) Oil sample 1 Oil sample 2 100μm or more 1 17 50~100μm 18 21 25~50μm 170 171 15~25μm 601 605 5~15μm 6282 6539 SAE AS4059F Particle Size Classification Level 5 Level 8

[0019] Therefore, the umbrella cover can prevent the oil from being contaminated again during sampling, ensuring that the oil sample truly reflects the state of the oil in the equipment, and improving the accuracy of oil particle size measurement. In addition, it is easy to use and carry when folded and unfolded in the form of an umbrella.

[0020] To further facilitate the carrying and cleaning needs of the sampling umbrella cover, the ring curtain 3 and the umbrella cover 2 are set as a two-body structure. Preferably, the ring curtain 3 and the umbrella cover 2 are detachably connected by a zipper, Velcro or snaps to facilitate installation and disassembly.

[0021] In addition, in order to facilitate the storage and carrying of the ring curtain 3, a pocket is provided at the edge where the umbrella cover 2 and the ring curtain 3 are connected, in which the folded ring curtain 3 can be placed, thereby improving the portability.

[0022] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the invention through the above description. The technical scope of the invention is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
