Lubricating oil is a medium for reducing friction and abrasion in various transmission systems, and can form a stable oil film between contact surfaces to avoid direct contact of friction pairs, so that the power consumption of equipment is fully reduced. The performance of the lubricating oil directly affects the operating efficiency and the service life of the whole system. And in the initial stage of fault formation, the oil signal can be captured preferentially before the vibration signal and the temperature signal, so that the oil analysis technology is rapidly accepted and favored in the friction-wear-lubrication field.
The oil analysis technology is to take oil used by equipment as an analysis object, reflect the current performance change of lubricating oil by extracting various valuable information contained in the oil, and simultaneously infer the health parameters of the equipment. The important step of oil analysis is to select a proper part for sampling based on the high-frequency fault characteristics and the maintenance frequency of the equipment. The sampling position is mostly the sampling of oil tank department. In the prior art, the devices used for sampling comprise a negative pressure sampler, a sampling bottle and a disposable sampling tube. The sampling bottle is connected on negative pressure sampler, and the one end of sampling tube is worn on negative pressure sampler and is stretched into the sampling bottle, and the other end of sampling tube stretches into in the oil tank, takes out the air in the sampling bottle through negative pressure sampler and forms the negative pressure, inhales the fluid in the oil tank into the sampling bottle, realizes taking a sample. After sampling, the sampling bottle is taken away firstly, the disposable sampling tube is cut off, the tube connected with the negative pressure sampler is drawn out from the lower part of the tube after being cut off, and the rest sampling tube is drawn out from the oil tank and then put into a garbage bag.
The existing oil sampling device has the following defects: firstly, the disposable sampling tube is inconvenient to store, and unnecessary external impurities can be introduced into the oil tank; secondly, when the disposable sampling tube is inserted into the oil tank, a plurality of adhesive impurities are arranged around the oil tank opening and possibly brought into the oil tank; when the sampling tube and the sampling bottle are assembled and disassembled, the internal sealing ring is easy to fall off, and the negative pressure sampler cannot form negative pressure in the sampling bottle after falling; fourthly, after the equipment is shut down, the temperature of the extracted oil sample is higher, and scalding is easily caused when the sampling bottle is grasped.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a negative pressure heat insulation sampler for sampling lubricating oil, so as to achieve the technical disadvantages of the conventional lubricating oil sampling device, such as easy introduction of contaminants into an oil tank, easy falling of a seal ring to cause sampling failure, and easy scalding of a sampling bottle.
The invention relates to a negative pressure heat insulation sampler for sampling lubricating oil, which comprises a negative pressure sampling bottle and a sampling tube, wherein the negative pressure sampling bottle comprises a bottle body, a bottle cap in threaded connection with the opening of the bottle body and a rubber sealing plug which is arranged in the bottle cap and the lower end surface of which is pressed on the end surface of the bottle opening;
the sampling tube comprises a hard tube plug for inserting the rubber sealing plug and a hose connected with the hard tube plug;
the negative pressure heat insulation sampler for lubricating oil sampling further comprises an anti-pollution joint, wherein the anti-pollution joint comprises a thread outer sleeve connected with the oil tank opening in a threaded manner and a central guide pipe arranged at the central part of the thread outer sleeve and used for guiding the hose of the sampling pipe into the oil tank.
Furthermore, the outer surface of the bottle body is provided with anti-skid bulges.
Further, a hand-held part is arranged on the hard pipe plug.
The invention has the beneficial effects that:
1. according to the negative-pressure heat-insulation sampler for sampling lubricating oil, the anti-pollution joint is arranged to isolate the oil tank opening, so that the technical problem that pollutants at the opening part of the oil tank are brought into the oil tank by the hose when the hose of the sampling pipe is put into the oil tank is solved.
2. The invention relates to a negative pressure heat insulation sampler for sampling lubricating oil, which adopts a rubber sealing plug arranged in a bottle cap to seal a bottle body, and when a hard pipe plug is inserted into the rubber sealing plug, the rubber sealing plug can be tightly wrapped and attached on the outer surface of the hard pipe plug under the action of self resilience force, so that a good sealing effect can be formed, and the negative pressure in a negative pressure bottle can be ensured to suck oil in an oil tank. And after sampling is finished, the hard pipe plug of the sampling pipe is pulled out, the rubber sealing plug can be closed and sealed again, and the sample can be prevented from being polluted in the transferring process.
And when the oil in the sampling bottle needs to be poured out after sampling, the bottle cap and the bottle body are in threaded connection, so that the bottle cap and the rubber sealing plug in the bottle cap can be conveniently taken down together, and a lubricating oil sample in the sampling bottle can be conveniently poured out.
Meanwhile, the rubber sealing plug is reliably fixed by the bottle cap, namely the bottle opening, so that the problem of falling-off is avoided, and the sampling success rate is high.
3. The negative pressure heat insulation sampler for sampling lubricating oil is characterized in that the heat insulation sleeve is sleeved outside the bottle body of the negative pressure heat insulation sampler, so that the problem of scalding when the sampling tube is pulled out after the sampling bottle is filled with high-temperature oil is solved.
