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, entrance 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 tops by pipeline, and another interface of repairing stop valve 12 is connected with Sheng oil funnel 1; An interface of entrance stop valve 10 is connected with oil holder 2 tops by pipeline, and another interface of repairing stop valve 12 is refrigerant entrance 9; An interface of outlet shutoff valve 5 is connected with oil holder 2 bottoms by pipeline, and another interface of outlet shutoff valve 5 is compressor connector 6.
When use, refrigeration oil 18 is added to oil holder 2 from containing oil funnel 1; Then the low pressure of compressor connector 6 and compressor 14 being scouted to mouth 15 is connected, refrigerant entrance 9 is connected with the high pressure scouting mouth 16 of compressor 14, completes compressor repairing by the low pressure scouting mouth 15 that the high pressure refrigerant introducing oil holder 2 of the high pressure scouting mouth 16 of compressor 14 is pressed into compressor 14 by refrigeration oil 10.Also can be connected with refrigerant tank 17 by refrigerant entrance 9, by the high pressure refrigerant of refrigerant tank 17 being introduced to oil holder 2, refrigeration oil is pressed into the low pressure scouting mouth 15 of compressor 14.
The present invention is without purchasing expensive supercharging equipment, makes full use of the power that compressor of air conditioner produces or the high pressure that utilizes refrigerant tank self, just refrigeration oil covered in the air-conditioning of oil starvation easily.By the aperture of outlet shutoff valve, easily regulate repairing speed.The present invention is air-conditioning is produced, maintenance, repair provide a set of simple and direct, effective refrigeration system recharging oil device.
Compressor connector 6 is connected with the low pressure scouting mouth 15 of compressor and refrigerant entrance 9 is recommended as fluoridize flexible pipe 13 with the pipeline that high pressure scouting mouth 16 or the refrigerant tank 17 of compressor 14 are connected.Conventionally low pressure is scouted mouth 15, high pressure is scouted mouth 16 and is charging valve or Self-sealing valve unidirectional, with thimble, and therefore fluoridize flexible pipe 13 has at least one end that the nut with thimble should be set.Oil holder 2 can be made 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, entrance stop valve 10 and repairing stop valve 12 are all selected and can pressure-bearing 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 long as far as possible outlet shutoff valve 5 and the oil pipe of entrance stop valve 10 stretch into oil holder 2 should be short as far as possible.
Adopting compressor of air conditioner recharging oil device of the present invention is that the concrete operation of compressor repairing is as follows:
A, Sheng oil: close outlet shutoff valve 5, open repairing stop valve 12, entrance stop valve 10, by contain oil funnel 1, repairing stop valve 12 by refrigeration oil 18 slowly to interior the Shengs oil of oil holder 2, until entrance ends 10 while overflowing, close successively repairing stop valve 12, entrance stop valve 10.
B, connecting leg (being divided into two kinds of modes)::
Without refrigerant tank 17 union modes: under compressor 14 shutdown situations, adopt 13, one of two fluoridize flexible pipes to connect entrance stop valves 10 and high pressure and scout mouthfuls 16; Another root connection outlet stop valve 5 and low pressure are scouted mouth 15.
While connecting fluoridize flexible pipe 13, should first be connected and tighten with outlet shutoff valve 5 with entrance stop valve 10, then the nut with thimble is scouted to mouth 16 and is connected and tightens with low pressure scouting mouth 15, high pressure respectively, and without leakage.Connect the rear cold-producing medium that utilizes and discharged the air in each parts.
There are refrigerant tank 14 union modes: the same except access high pressure being scouted to nut reconfiguration other connection the refrigerant exit of refrigerant tank 17 of mouthfuls 16 fluoridize flexible pipe 13.
D, repairing: start compressor 14, (while having refrigerant tank 17, open refrigerant tank 17 fill fluorine valve), and order is slowly opened outlet shutoff valve 5, entrance stop valve 10, and the speed of oiling is unsuitable fast.Control the speed of oiling by regulating the aperture of outlet shutoff valve 5.Complete orderly close-down entrance stop valve 10 after repairing, outlet shutoff valve 5.
E, recovery: after repairing, compressor 14 should be worked 10 points more than kind, close compressor; Remove tube connector and other devices; Ensure to scout mouthful check valve without 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 that connects oil holder 2 and outlet shutoff valve 5.The mobility status that can observe from liquid-sighting glass 4, liquid-sighting glass 4 is selected and can pressure-bearing be not less than 4.95Mpa respective accessory.
In order to add repairing amount accurately, entrance stop valve 10 comprises and vacuumizes interface 11.Connect vaccum-pumping equipment and take air and airborne impurity and the moisture in oil holder 2 away by vacuumizing interface 11, avoid its interference to repairing amount.
Topple over for fear of fixing oil holder 2, need to have associated anchor or fixed form.Oil holder 2 remaining part fixed forms of the present invention are 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 the housing of repairing stop valve 12 and entrance stop valve 10 is all connected with upper support seat 8; 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 tops should arrange is convenient to the through hole 3 that outlet shutoff valve 5 and liquid-sighting glass 4 pass.
