A kind of air-conditioner host oil-filling device, comprise compressor and oil storage tank, the exhaust port side of described compressor and suction port end are connected with respectively the first connecting tube and the second connecting tube that tail end stretches into oil storage tank inside, and the first connecting tube stretches into the degree of depth of oil storage tank less than the second connecting tube, is provided with stop valve on the top of the first connecting tube and the second connecting tube.
Further, described exhaust port side is connected with outlet pipe, is provided with the first pressure detection mouth at outlet pipe, and the top of described the first connecting tube is connected on the first pressure detection mouth by pipeline; Described suction port end is connected with suction tude, is provided with the second pressure detection mouth in suction tude, and the top of described the second connecting tube is connected on the second pressure detection mouth by pipeline.
Further, the tail end of described the first connecting tube is positioned at the top of oil storage tank, and the tail end of the second connecting tube is positioned at the bottom of oil storage tank.
Further, be provided with on the outer side wall of described oil storage tank for the level meter of measuring the quantitative change of oil storage tank interior oil.
Further, the top of described oil storage tank is provided with oil hole.
The utility model has the advantages that:
The air-conditioner host oil-filling device that reaches described in the utility model, can be in the air-conditioner host running, utilize the pressure reduction between exhaust outlet of compressor end and the suction port end, the lubricant oil of oil storage tank inside is passed through the inside that pipeline easily pushes to machine set compressor, play the effect of lubricated machine set compressor, operation is simple, manual operation is convenient, in the situation of the normal operation that does not affect air-conditioner host, can finish the oiling operation, overcome simultaneously the loaded down with trivial details deficiency of existing air-conditioner host oiling operation; The tail end of the first connecting tube is positioned at the top of oil storage tank, and the tail end of the second connecting tube is in the bottom of oil storage tank, so that the pressure reduction that exhaust port side and suction port end produce can play to the lubricant oil of oil storage tank inside the propelling movement effect of arriving very much; Top at the first connecting tube and the second connecting tube is provided with stop valve, cooperates level meter, and the unit volume read-out what can accurately be controlled oil storage tank and are.
Description of drawings
Fig. 1 is the structural representation of a kind of air-conditioner host oil-filling device in the utility model.
Embodiment
In the air-conditioner host running, because unit circulation pipeline is long, there is easily more trapped fuel dead angle; in addition, usually can occur the problem of oil leak in the unit operation, therefore need make-up oil; with the lubrication effect of guaranteeing that machine set compressor is good, and then can work.Conventional method for the air-conditioner host oiling, after the air-conditioner host stall, first part or all of refrigeration agent is bled off, open the part pipeline of machine set compressor, toward the inner charging-up lubricant oil of pipeline, then pipeline is installed, through hunting leak, find time, replenish the refueling operation of finishing air-conditioner host after refrigeration agent operates, this refueling operation complex procedures, manual operation is loaded down with trivial details.
Based on this, when the inventor utilizes the air-conditioner host operation, the pressure reduction that produces between exhaust port side and the suction port end, easily that the lubricant oil of oil storage tank inside is inner through the compressor that pipeline pushes to unit, realize the lubricated operation of compressor, guarantee the normal operation of machine set compressor, whole refueling process operation is simple, easy to operate.The below engages accompanying drawing embodiment of the present utility model is described further:
In conjunction with shown in Figure 1, a kind of air-conditioner host oil-filling device, comprise compressor 1 and oil storage tank 2, compressor comprises exhaust port side and suction port end, the exhaust port side of compressor is connected with outlet pipe 3, be provided with the first pressure detection mouth 50 at outlet pipe, be used for the refrigerant pressure of monitoring compressor exhaust port side; The suction port end of compressor is connected with suction tude 4, is provided with the second pressure detection mouth 51 in suction tude, and for detection of the refrigerant pressure of compressor inlet end, in the air-conditioner host running, the air pressure of exhaust port side is higher than the air pressure of suction port end.Be connected with the first connecting tube 60 by pipeline on the first pressure detection mouth 50, the top of the first connecting tube is positioned at the outside of oil storage tank, tail end stretches to the inside of oil storage tank, be connected with the second connecting tube 61 by pipeline on the second pressure detection mouth 51, the top of the second connecting tube is positioned at the outside of oil storage tank, tail end stretches to the inside of oil storage tank, and the first connecting tube stretches into the degree of depth of oil storage tank inside less than the second connecting tube.The tail end of the first connecting tube 60 is positioned at the top of oil storage tank 2, preferably is positioned at the top of oil storage tank near oil storage cover place, and the tail end of the second connecting tube 61 is positioned at the bottom of oil storage tank 2, preferably is positioned at the bottom of oil storage tank near the oil storage tank bottom.Be provided with stop valve 7 on the top of the first connecting tube and the top of the second connecting tube.
