ZR / VR series of flexible scroll compressor (application tips) storage and handling * Storage: Using carton packaging, should be stored in dry and ventilated environment, external box with air holes and the same period; * Handling: in the handling process, the compressor should remain vertical. Remove the sealing plug * compressor factory filled a certain pressure, dry air, and then sealed with a rubber seal plug; * When on-line, you should open the vent plug, and then open the suction intake pipe plug * Cleaning the mouth with a cloth circle, wipe the film layer, easy welding; * SUMMIT series suction nozzle located near the oil level, more should be cleaned before welding the inner film layer suction nozzle fixed foot * Copeland with a rubber ring and copper sleeve * The rubber ring on the compressor when the compressor bottom booties vertical lift * were placed in a steel casing bolts, and then install the compressor hanging into place, then gently tighten the nut with washers: 1, the installation is recommended torque for 13 ± 1Nm; 2, rubber rings and steel casing with a gap of 2mm month; 3, tighten the nut with a washer, if the force of the General Assembly is tilted even rupture the casing, which will cause vibration and noise. A compressor suction and discharge pipe welding, suction and discharge pipes for copper pipe; 2, preferably containing at least 5% silver solder, if you use less than 2% silver solder, there should be very good skills as a guarantee; 3, the link gap should ensure 0.1mm ~ 0.3mm 4, the nozzle is not overheated, the welding time of 15 to 20 seconds 5, a detailed description of the application guide 6, the solder will cause the failure of the compressor into the vacuum and filling 1, should the high pressure side and the low side while vacuuming 2, in a vacuum, not pressure test; 3, preferably at the same time filling the high side and low side, or only from the high-pressure side filling; 4, if only from the low pressure side of the filling, may lead to scroll axial seal, temporarily unable to start. Electrical connection * Note terminal symbol corresponding press sequence: 1, single-phase C, R, S 2, the three-phase T1, T2, T3, clockwise in the electrical wiring * Ground box grounding screw holes for belt locking Automatic Screw; * Use tools to cover both sides of the electrical hook inward pressure to open the electrical box cover; * for connection column with screw connection, attention control start tool torque, otherwise damage or cause internal screw thread posts fracture. Electrical Safety * When the pressure test, a high level will affect the insulation; a large number of refrigerant migration induced internal press, so that the motor is a mixture of refrigerant and oil intrusion, resulting in increased leakage current; 2, if the leakage current is increased , you can run the compressor minutes, so a lot of the refrigerant leaving the compressor, the level is reduced. Further testing, return to normal. * Copeland pressure test specifications: 1800V / 1sec three phase scroll compressors certain direction of rotation, like the three-phase compressor, scroll compressor can only be compressed in one direction of rotation. The direction of rotation of three-phase power supply depends on the phase of the compressor, there is a 50% probability of the compressor running in the opposite direction, so the system is installed and running before you want to be very careful to check the operation of the compressor to determine whether the correct direction. The correct direction of rotation of the judgment can be carried out by the low-pressure compressor was observed rising power. When the compressor has a higher noise inversion, while current is less than the current value of the corresponding sample. Three-phase inversion scroll compressor does not affect its short lifetime. In fact, after a period of time reversal compressor, built to protect the compressor will cut off the power and action. If the compressor reverse, just to the three-phase power supply can swap any two phases. * Standard production line running machine should be checked with the test machine matches: 1 large flow constraints, resulting vacuum operation and overheating; 2, flow constraint is small, resulting in back was much bigger cause noise and other "failures." * Low start, ensure that 90% Copeland voltage start; * a brief power interruption will result in a single phase compressor reversed, there will be noise but will not harm the compressor, the protector will eventually disconnect; * clog the suction side will have depth vacuum operation, although the floating seal protection, but detrimental to the compressor; * will cause a malfunction in the solder into the compressor; * Copeland Compliant Scroll compressor has run-in effect; 1, after 24 hours run-run, to achieve optimal performance ; 2, run after run-in, there will be noise reduction, compressor power is reduced and the current is reduced. * For offline Copeland compressors shall promptly notify the engineer to handle and determine: 1, does not need to be returned immediately determine compressor plant analysis, application sealed compressor inlet nozzle Sese and packed evacuation Copeland local offices treatment; 2, need to be returned compressor plant analysis, should fill out the model, serial number and cause of the malfunction. Function tests scroll compressor suction valve closed compressor compressor runs to be able to check the suction pressure to the minimum value as judged by the quality of the compressor. In fact such a test may damage the scroll compressor. However, some of the following diagnostic methods can be used to determine whether a scroll compressor functioning: 1. Check the supply voltage is normal unit 2, if the built-in motor overload tripped or internal signs of a short circuit to ground, you must check the motor windings and ground short circuit. If the motor protection tripped, the compressor must be fully cooled to reclose protector. 3, indoor routine checks outside of the fan is operating normally. 4, suction and discharge side of the gauge connection, turn on the compressor power. If the suction pressure is lower than normal, there may be a charge less, or internal system blockage 5, if the suction pressure does not drop, the exhaust pressure rise to normal levels, swap any two terminals of the power compressor wiring to ensure proper operation of the compressor direction, if the pressure does not reach any of the normal course, the four-way valve or compressor may be damaged, the compressor will be restored to the original wiring solution, check with the conventional four-way reversing judgment method The quality of the valve. 6, if the four-way valve inspection good, will have the current value and the current value of the compressor in the compressor performance curve under the same working conditions on the comparison, the deviation value exceeds (± 15%), it can be judged compressor has been damaged. Rework a welding system components, you can be discharged refrigerant emissions from both the refrigerant should be high side and low side; 2, as only the high-pressure side, scroll seals the cause refrigerant remains in the low pressure side, when The next weld connecting tube, and a mixture of refrigerant oil will be ejected, and the flame was lit in the face. Refrigeration lubricants oil type and replace HCFC refrigerants (eg R22) applications, Copeland Scroll compressors 3GS oil, specifically the amount of oil can refer to previous page help. In HFC refrigerants (eg R407C, R134a) applications, Copeland Scroll compressors have to use POE lubricant recommended Ultra22CC, also filling Mobil Arctic EAL22CC or ICI Emkarate RL32CF lubricants.
