Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Compressor of air conditioner recharging oil device comprises oil holder 2, repairing stop valve 12, inlet stop valve 10, outlet shutoff valve 5 and contains oil funnel 1; An interface of repairing stop valve 12 is connected with oil holder 2 top by pipeline, and another interface of repairing stop valve 12 is connected with Sheng oil funnel 1; An interface of inlet stop valve 10 is connected with oil holder 2 top by pipeline, and another interface of inlet stop valve 10 is refrigerant inlet 9; An interface of outlet shutoff valve 5 is connected with oil holder 2 bottom by pipeline, and another interface of outlet shutoff valve 5 is compressor connector 6.
During use, refrigeration oil 18 is added oil holder 2 from Sheng oil funnel 1; Then compressor connector 6 is scouted mouth 15 with the low pressure of compressor 14 to be connected, refrigerant inlet 9 is scouted mouth 16 with the high pressure of compressor 14 and is connected, and scouts mouth 15 namely complete compressor repairing by low pressure refrigeration oil 10 being pressed into by the high pressure refrigerant introducing oil holder 2 of the high pressure of compressor 14 scouting mouth 16 compressor 14.Also refrigerant inlet 9 can be connected with refrigerant tank 17, scout mouth 15 by low pressure refrigeration oil being pressed into by the high pressure refrigerant of refrigerant tank 17 introducing oil holder 2 compressor 14.
The present invention, without the need to the supercharging equipment of purchasing expensive, makes full use of the power that compressor of air conditioner produces or the high pressure utilizing refrigerant tank self, is just covered in the air-conditioning of oil starvation by refrigeration oil easily.By the aperture of outlet shutoff valve, easily regulate repairing speed.The present invention is the recharging oil device that air-conditioning is produced, maintenance, repair provide a set of simple and direct, effective refrigeration system.
Compressor connector 6 and the low pressure of compressor are scouted mouth 15 and to be connected and refrigerant inlet 9 and the high pressure of compressor 14 are scouted the pipeline that mouth 16 or refrigerant tank 17 be connected and be recommended as fluoridize flexible pipe 13.Usual low pressure scouts mouth 15, high pressure is scouted mouth 16 and is unidirectional, to be with thimble charging valve or Self-sealing valve, and therefore fluoridize flexible pipe 13 has at least one end should arrange the nut of band thimble.Oil holder 2 can make corresponding container size according to repairing amount (unit: milliliter), and its maximum working pressure (MWP) should be not less than 4.95Mpa; Outlet shutoff valve 5, inlet stop valve 10 and repairing stop valve 12 are all selected and pressure-bearing can be not less than the corresponding valve member of 4.95Mpa.The oil pipe of repairing stop valve 2 stretch into oil holder 1 should the oil pipe of long as far as possible outlet shutoff valve 5 and inlet stop valve 10 stretch into oil holder 2 should be short as far as possible.
Compressor of air conditioner recharging oil device of the present invention is adopted to be that the concrete operation of compressor repairing is as follows:
A, Sheng oil: close outlet shutoff valve 5, open repairing stop valve 12, inlet stop valve 10, by containing oil funnel 1, refrigeration oil 18 is slowly contained oil by repairing stop valve 12 in oil holder 2, until when entrance cut-off 10 is overflowed, close repairing stop valve 12, inlet stop valve 10 successively.
B, connecting leg (being divided into two kinds of modes)::
Without refrigerant tank 17 union mode: under compressor 14 shutdown situation, two fluoridize flexible pipes 13, are adopted to connect inlet stop valve 10 and high pressure scouting mouth 16; Another root connection outlet stop valve 5 and low pressure scout mouth 15.
When connecting fluoridize flexible pipe 13, should first be connected with outlet shutoff valve 5 with inlet stop valve 10 and tighten, then the nut of thimble scouts mouth 15 with low pressure respectively, high pressure is scouted mouth 16 and is connected and tightens by being with, and No leakage.Connect the rear cold-producing medium that utilizes and discharge air in each parts.
There is refrigerant tank 14 union mode: except nut reconfiguration other the connection except the refrigerant exit of refrigerant tank 17 access high pressure being scouted the fluoridize flexible pipe 13 of mouth 16 is the same.
D, repairing: start compressor 14, (have to open during refrigerant tank 17 refrigerant tank 17 fill fluorine valve), order slowly opens outlet shutoff valve 5, inlet stop valve 10, and the speed of oiling is unsuitable fast.By the speed regulating the aperture of outlet shutoff valve 5 to control oiling.Complete orderly close-down inlet stop valve 10, outlet shutoff valve 5 after repairing.
E, recovery: after repairing, compressor 14 should work more than 10 points of kinds, close compressor; Remove tube connector and other devices; Ensure to scout mouth check valve No leakage.
In order to observe and control repairing speed and time, compressor of air conditioner recharging oil device comprises liquid-sighting glass 4, and liquid-sighting glass 4 is arranged on the pipeline of connection oil holder 2 and outlet shutoff valve 5.The mobility status can observed from liquid-sighting glass 4, liquid-sighting glass 4 is selected and pressure-bearing can be not less than 4.95Mpa respective accessory.
In order to add repairing amount accurately, inlet stop valve 10 comprises and vacuumizes interface 11.Connect vaccum-pumping equipment take the air in oil holder 2 and the impurity in air and moisture away by vacuumizing interface 11, avoid it to the interference of repairing amount.
In order to avoid fixing oil holder 2 is toppled over, need associated anchor or fixed form.Oil holder 2 remaining part fixed form of the present invention is as shown in Figure 1: compressor of air conditioner recharging oil device comprises interconnective upper support seat 8 and lower support seat 7; Oil holder 2 is fixed in upper support seat 8, and the housing of repairing stop valve 12 is all connected with upper support seat 8 with the housing of inlet stop valve 10; Outlet shutoff valve 5 and liquid-sighting glass 4 are positioned at lower support seat 7, and the housing of outlet shutoff valve 5 is connected with lower support seat 7.Lower support seat 7 top should arrange the through hole 3 be convenient to outlet shutoff valve 5 and liquid-sighting glass 4 and passed.
