System KB can be discharged, added oil, вакуумирована and is charged by a coolant by means of special зарядной the station applied to service of central airs, or by means of the complete set of hoses and коллекто ра manometres and 420 ml of capacities for coolant storage. For joining of hoses зарядной stations or коллекто ра manometres are used transitive details from the complete set of manometres. There are direct and angular (90-degree) adapters. At work connected with system KB depressurization, it is necessary to use goggles and to wrap up a pure fabric штуцерные connections.
It is necessary to work in good проветривае мом a premise and to avoid a coolant steam inhalation. Hit in eyes of a liquid coolant can lead травмированию.
1) Before removal and replacement of any element of system KB it is necessary anticipate тельно completely to discharge system from a coolant.
2) At откачке air and gymnastics of system a coolant it is necessary to use the complete set of cranes and manometres.
3) a system Discharge, откачку air and gymnastics of system the coolant authorises to make only through technologists ческий the union located in a contour of low pressure.
4) At a discharge and system KB gymnastics it is forbidden to attach pipelines of a high pressure and other pipelines to the technological union located in a contour of a high pressure.
It is forbidden to disconnect a hose of a manometre from the transitive union when the pipeline is connected to system SQ. At a detachment трубопро water it is necessary to turn out an adapter from the technological union. It is forbidden to disconnect зарядный a hose from the block of manometres if it is connected to the technological union in a contour of low pressure. It will lead to a full discharge of system through the open valve of the technological union and possible травмированию the personnel because of coolant leak.
System KB discharge
Discharge of system KB without use зарядной stations
At replacement of any knot or system KB detail it is necessary to discharge completely preliminary system from a coolant. The discharge is made only through technologists ческий the union in a contour of low pressure.
1) At the switched off ignition to remove a protective cap from the technological union of a contour of low pressure. The union is located on the receiver case. To connect to the union зарядную station or a collector of manometres. The system discharge can be made also by means of a hose of a manometre and capacity with refrigerating oil, fig. the Discharge of system KB without use зарядной stations see. One end of a hose is located in capacity, and another is slowly connected to the technological union on the receiver case. At hose connection opens запорный the valve of the union and the discharge of system SQ. begins If the discharge does not occur, it is necessary to check up serviceability of a pusher in a tip of a hose which opens the valve.
2) After a full discharge of a contour of low pressure to check up presence остаточ ного pressure in a high pressure contour (through the union of this contour).
3) If is available residual pressure to discharge a high pressure contour, operating similarly. (Residual pressure testifies to presence of resistance in a high pressure contour. To find and eliminate malfunction before pumping out air and to fill system).
4) After a full discharge of system (gas does not leave any more a hose at completely навернутом a tip) to measure and write down quantity of the collected refrigerating oil. If than 15 ml of oil in system it is necessary to add the same quantity of fresh refrigerating oil of mark 525 were typed more. Besides, it is necessary to add so much oil, how many remains in the removed unit. Having added make to откачки air and a gymnastics of system a coolant.
The refuelling capacity of system KB with compressor V-5 makes 240 ml of refrigerating oil. At system work on coolant R-12 oil of mark 525 is applied, and at work on coolant R-134a - oil РАG.
At replacement of units of system KB it is necessary to add in system oil in following quantities:
The Compressor – if than 30 ml of oil are merged less, to add 60 ml. If than 30 ml are merged more, to add the same quantity of oil. Receptions correct plum of oil from the compressor are resulted more low.
The Evaporator – to add 90 ml of oil.
The Condenser – to add 30 ml of oil.
Receiver – to pour in in a new receiver of oil of 105 ml.
Losses of oil because of considerable leaks of a coolant.
1) If has occurred fast pressure drop in system KB, together with хладаген the volume is lost about 90 ml of oil. Any malfunctions connected with a fast discharge of system are accompanied by similar losses of oil. Незначитель ные coolant leaks do not lead to oil losses.
2) At the replacement of any unit connected with the big losses of a coolant to add in system of refrigerating oil of 90 ml. At system work on coolant R-12 oil of mark 525 is applied, and at work on coolant R-134a – oil PAG. In addition to add in system oil in quantity which depends on the replaced unit, points)-d) see above.
3) to Add oil follows directly in the established unit. If it is inconvenient, oil add in a receiver.
1) with the help зарядной stations;
2) by means of capacity with a coolant.
Under no circumstances it is impossible to use spirit for drainage of system SQ. It will lead to failure of details of system.
Calibration of manometres
Before откачкой air it is necessary to check up a vacuum manometre and serviceability of vacuum system. On the disconnected manometre to check up arrow position: she should specify in the zero middle. Slightly to knock on the device and to be convinced that an arrow not заедает. If necessary to expose an arrow of the device on zero.
1) to Uncover a manometre.
2) Keeping a hand the adjusting screw of an arrow, cautiously to turn an arrow on zero. Slightly to knock on the device and to be convinced that an arrow not заедает. To establish into place a cover.
2) the high pressure Valve зарядной stations should be always closed.
3) All operations on откачке air and coolant gymnastics to make through the technological union of a receiver.
4) Observance of these instructions will help to prevent casual connection of a contour of a high pressure of system KB with a filling station in case of an error as opening of valves at the working compressor.
1) to Attach a collector of manometres (adaptation J 23575-01) as follows.
And. To attach a vacuum manometre to the receiver union.
. The central union of a collector to connect to capacity with a coolant
Century to Attach a high pressure manometre to the vacuum pump.
2) For откачки air from system KB slowly to open valves of high and low pressure (fig. Gymnastics of system KB a coolant from capacity see) and to include the vacuum pump. To continue to pump out air before achievement разряжения 711... 737 mm Hg on a vacuum manometre. It is necessary to notice that everywhere at the operation description откачки air value разряжения 711 is resulted... 737 mm Hg It разряжение correspond to conditions on a sea level. If necessary it is necessary to enter the amendment reducing nominal разряжение on 25 mm Hg on each 300 m of lifting above sea level. For example, at height of 1500 m above sea level nominal разряжение it is equal 584... 610 mm Hg If demanded nominal разряжение are not reached, it is necessary to close the vacuum valve, to switch off the vacuum pump and to check up connections and the pump on tightness.
3) At achievement demanded разряжения in system KB to close the valve of a high pressure and to switch off the vacuum pump.
4) On a vacuum manometre to check up tightness of system. Разряжение should be stable within 5 minutes. If systems it is tight, to disconnect a vacuum hose from a collector and to start gymnastics of system KB a coolant.
5) If разряжение it is not kept within 5 minutes to fill in system KB of a coolant of 420 ml and to check up it on presence of leaks. Then to discharge system and to eliminate thinnesses. To repeat operation откачки air.
2) to Turn capacity and to establish it on scales. To open the final crane of capacity. To merge 480 ml of a coolant in system KB through the union of a contour of low pressure.
3) After plum of a coolant of 480 ml at once to include the compressor and the maximum giving of air by a supercharger for realisation of full refuelling of system by a coolant. Gymnastics operation can be accelerated by means of the fan of the big productivity blowing in the condenser. If to maintain temperature of the condenser at lower level in comparison with capacity, the gymnastics will pass faster.
4) to Close the drain crane of capacity and to allow to work to the engine during 30 with for clearing of pipelines and tubes of manometres of a coolant.
5) At the working engine to disconnect a refuelling hose with an adapter from the receiver union. A detachment to make quickly in order to avoid losses of a coolant from system.
It is forbidden to disconnect a hose of a manometre from an adapter if the pipeline is connected to system SQ. it is necessary to turn out at first an adapter from the technological union of a receiver. It is not necessary to disconnect also заправочподключен to a receiver. It will lead to a full discharge of system KB through the return valve of the union of a receiver and possible травмированию the personnel leaving steams of a coolant.
6) to Establish on the receiver union a protective cap.
7) to Switch off the Engine.
8) to Check up tightness of system KB by means of an electronic tester.
9) to Start the Engine.
