The invention relates to the field of instrument manufacturing equipment, in particular to a device and method for cleaning a capillary tube of a separate measurement type thermometer. The device comprises a reagent can, wherein a liquid outlet pipe and an air inlet pipe are arranged on the reagent can, one end of the liquid outlet pipe is inserted into the reagent can, located below the liquid level of a cleaning agent and connected with a first filter, the other end of the liquid outlet pipe is connected with a capillary tube, and the reagent can is filled with the cleaning agent through a funnel. The device is characterized in that a liquid outlet pipe valve and a booster pump are arranged in the liquid outlet pipe sequentially, and a second filter is arranged between liquid outlet pipe valve and the booster pump; the capillary tube is connected with a waste liquid tube which is inserted into a waste liquid bottle. Compared with the prior art, the inner wall cleanness of the cleaned capillary tube is high, a basis is laid for the quality of a subsequent product, the potential quality hazard to the subsequent product can be avoided, the operation is convenient, the production efficiency is high, the production period is shortened, the cleaning agent for cleaning can be recycled, and the cost is reduced; the filters are arranged in a pipeline, so that particles in the cleaning agent can be prevented from blocking the capillary tube.
Description
Technical field
The present invention relates to instrument and meter manufacturing equipment field, be specifically related to a kind of indirectly measuring type thermometer capillary tube cleaning device and method.
Background technology
Capillary is applicable in domestic air conditioning, refrigerator, refrigerator-freezer or the product such as high-accuracy instrument and high-precision medical instrument.In capillary product, be most widely used with copper capillary tube, it is thin that such tubing has external diameter, endoporus is little, stretches and must use the feature of lubricating oil, because being used for precision equipment, inwall cleannes are required strict: moisture is no more than 0.1g/m2, oil content is no more than 0.1g/m2, and inwall residue is no more than 0.2g/m2, so just proposes a difficult problem to manufacturer.Traditional cleaning way, production efficiency is low, cleaning frequency is long, waste cleaning agent, and the cleaning length of capillary is short, generally can only clean 3-5 rice, limit the use occasion every testing temperature meter to a great extent, be also difficult to reach the instructions for use of inwall cleannes, bring hidden danger often to the precision instrument after producing, the serious complete machine that causes is scrapped, wasting manpower and material resources.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of indirectly measuring type thermometer capillary tube cleaning device and method, can realize capillary tube inner wall cleaning fast, cleannes are high.
Indirectly measuring type thermometer capillary tube cleaning device, comprise reagent pot, reagent pot is provided with drain pipe, air inlet pipe, one end of drain pipe to be inserted in reagent pot and is positioned under cleaning agent liquid level, and being connected with the first filter, the other end of drain pipe connects capillary, and cleaning agent injects reagent pot by funnel, it is characterized in that: in described drain pipe, be provided with fluid pipe valve, booster pump successively, between fluid pipe valve and booster pump, be provided with the second filter; Described capillary is connected with sewer pipe, and sewer pipe inserts in waste liquid bottle.
The length of described capillary is 10 ~ 15m.
