Description Electronic Expansion Valve Repair Tool (without Power Supply) for Variable-frequency Air Conditioner Description: This is a new generation of electronic expansion valve tester and repairer. Its driving output adopts imported high-power independent drive tube, so its driving torque can reach 5 times, and it has a forced repair mode to ensure repair effects. The repairer has an automatic buck-boost function. It is compatible with 12V/24V 5-wire and 6-wire electronic expansion valves, and is suitable for electronic expansion valves of various models and specifications. It supports fault detection, manual valve adjustment, automatic positioning, and forced repair mode. Key parameters are open to user to set. Fault detection function: When the expansion valve failure of air conditioner occurs, we need to accurately determine on the spot whether it is the failure of the electronic expansion valve drive circuit or the failure of the expansion valve itself. Through the detection function of the repairer, we can determine the fault point on the spot, and avoid huge costs of the materials and labor caused by valve removal, valve replacement, vacuuming and refrigerant replenishment. Manual adjustment of electronic expansion valve: When repairing or assembling air conditioners, the electronic expansion valve is generally closed because the air conditioner unit is shut down. This will cause a lot of troubles for vacuuming and refrigerant charging. By adjusting the electronic expansion valve, users can open the electronic expansion valve to any opening degree by manual or automatic positioning. With advanced precise subdivision control technology, it can realize one-step precise fine adjustment. When the drive circuit of the original control electronic expansion valve fails, users can adjust the electronic expansion valve to the appropriate opening through the manual valve adjustment function of the repair device, and then remove the expansion valve plug, and the electronic expansion valve will remain at the current opening. When the electronic expansion valve becomes a fixed throttle component, the unit can resume normal operation. Automatic repair function: Stuck electronic expansion valve is a frequent fault. Especially, when the frequency conversion multi-connected air conditioner electronic expansion valve is used in a large number, and both the external machine and the internal machine are equipped with electronic expansion valves, it often occurs that the electronic expansion valve cannot be opened and the electronic expansion valve cannot be closed completely. Through the advanced automatic repair function of the tester, the electronic expansion valve can be quickly repaired directly on board. Key Components of the Tester: – The repairer adopts a high-power automatic buck-boost circuit: Suitable for 12V and 24V 5-wire and 6-wire electronic expansion valves – Four imported high-power Darlington transistors are used to drive the four-phase coil of electronic expansion valves. The maximum output current can reach 8A, which can generate 5 times the torque to ensure repair effect. Maintenance Skills of Two Common Problems: 1. The expansion valve cannot be opened or the expansion valve is seriously stuck. Use the standard mode to repair the expansion valve more than 10 times but still cannot open the expansion valve. You can set the repair device to 24V forced mode. If the expansion valve is repaired more than 5 times and stuck seriously, it can generally be repaired. 2. The expansion valve cant be closed completely. The expansion valve can operate normally, but when it is adjusted to the minimum, it cannot be completely closed. Please set the tester automatic-positioning parameter to the minimum. Then power up the tester. When the repair tool completes automatic positioning and the digital tube displays 0, please disconnect the power supply and restart the repair tool for two positioning. If the expansion valve is still not closed, please set the driving direction of the tester to reverse and then position it twice. Attention: The precondition of the above operation is that the coil of the expansion valve is normal, the wiring is normal, and the maximum step number is set correctly. Package Included: – 1 x Electronic Expansion Valve Tester – 1 x Detection Cable – 1 x Universal Adapter Cable – 1 x Instructions Accessory Functions: – Detection Cable: to detect drive signal of electronic expansion valve of the original controller, and can also be used for self-detection of the repairer function. – Universal Adapter Cable: used for on-site quick transfer of various non-standard plug sockets. Note: – Power supply is not included in the package. Please prepare it by yourself. FAQ: 1. Which models is this product suitable for? Which electronic expansion valves can be used? Answer: This product is suitable for DC12V, DC24V, 5-wired and 6-wired electronic expansion valves regardless of size and model. 2. How long is the warranty period of the product? Answer: Products with non-human faults can be guaranteed for one year. 3. What is the repair principle? Answer: Using imported independent driving tube, driving torque of the product is 5 times that of the original controller driving chip, which can effectively force the stuck valve core in the electronic expansion valve and restore the normal function of the valve core rotating mechanism. 4. Is the repair rate high? Answer: Repair can be divided into two situations, namely, direct repair on board and separate repair off board. 4.1. On-board direct repair: Due to the different degree of stuck electronic expansion valve and different technical experience of operators, 100% repair success rate is not guaranteed. According to the actual repair effect statistics of users, the repair success rate is over 90%. 4.2. Separate repair: For the old electronic expansion valve or the electronic expansion valve that failed to be repaired on-board, users can remove the expansion valve and repair it separately. Inject rust remover into the valve body, soak and rinse, and start the repair function at the same time. The repair rate reaches 100%. The repaired electronic expansion valve can be lubricated by injecting refrigerant oil inside, and then it can be put on the machine again. Payment Terms 1.
