1. DYQ3 series liquid resistor starter is a new starting device for improving the starting capability of large and medium slip ring asynchronously and low-voltage squirrel-cage motor. The old-fashioned starting instruments ----adjustable rheostat, oil- immersed rheostat and cast iron rheostat ---have many disadvantages such as: having strong impact current (about 3-5 times for rated current in general) and cant bring a ideal effect etc., but all of the disadvantages can be overcome by the DYQ3 series liquid resistor starter. The DYQ3 series is used a special liquid resistor to be connected in series to the rotor circuit of large and medium slip ring motor, the liquid resistor get to work when the motor starting and it can automatic, stepless and continuous removal during the preset time, then the motor can start smoothly under ideal starting current condition. Eventually the motor can accelerate balanced. This plays an important role in protection of motor, electric equipment, power system and saving electricity. As well as the well-designed of system starting, stop, error protection, communication and display, making the liquid resistor starter have high degree of automation, small starting current (less than 1.3 times for rated current in general), can start successfully when power system have low voltage, and reducing the capacity of transformer remarkably. So DYQ3 series liquid resistor starter is the most ideal starting equipment for heavy load device such as: ball crusher, hoister, compressor, blower and water pump etc. 2. Model explanation 3.

Installation and debugging 7.1 installation and connection: 7.1.1. Control cabinet and resistor cubicle should be installed on the cement platform in which the water can easily drain; we should ensure that cabinet perpendicular to the horizontal and cabinet be fixed on the platforms channel steel. There should be cable channel under the control cabinet. 7.1.2. Put the electric cable (the cable should load enough current) of motor rotor in the starter control cabinet and connect it according to electric principle scheme, then connect the interlock control line. 7.1.3. Check the correction of line and thetightness of fastener. 7.1.4. Check the insulation resistance between liquid resistor and ground, the resistance should more than 5M¦¸ 7.2 Debugging: 7.2.1. Check the condition of liquid resistance boxs site and polar plates movement. Pick up the moving polar plate directly without liquid resistor, check its flexibility, if the result is no so good, should regulate the site of the liquid resistance box. 7.2.2. When primary circuit open in main motor, once closing the QF1 in start cabinet, the polar plate should move towards to reset key, or QF1 should be opened immediately, then exchange any two power lines of A, B, C three-phase, switching the test button SA, check the start working condition normal or not, then cut off SA, check the starter stop condition normal or not. 7.2.3. Compound liquid resistor 7.2.3.1 Pour pure water into the resistance box until its volume reach 80% of the boxs 7.2.3.2 Put three bags powder in three separate grooves, then add pure water again and make the liquid level keeping 5mm distance between the tank cap. 7.2.3.3 Switching the lifting motor, let polar plate go up and down several times, so that the liquid resistance can mix excellent. 7.3 Test the machine: Observe that whether the start current less than 1.3-3.5 times of rated current or not, if it is, the machine can put into use successfully; if not, the concentration of liquid resistance should be regulated, and please refer to the use and maintain parts to learn the detailed regulated methods. 8. Operation: 8.1 Startup (1). Closing the isolating switch for power supply of primary circuit (2). Energizing the starter, then the light of power and reset are illumed, polar plate reset automatically, then the light of allowing start is illumed, this indicate that the machine can start smoothly (3). Push the charge button, after charge process ending, push the start button, then the main motor start work and allowing start light is turned off, start light is illumed. When the start process ending, the machine start work automatically, then start light is turned off and the run light is illumed. 8.2 Close down Push the stop button, then the motor can stop work automatically, and the starter can reset automatically, so that it can prepare for next starting 9. Use and maintain If the power light is illumed, but allowing start light is not illumed, please check the liquid level, limit switch, contactor and elevator until allowing start light is illumed, then can go on starting. When the machine need stop no matter with what reason, please cut down the main switch. Its forbidden that switchoff the starters power when the main motor is also working. When overhaul is ending, starter empty-load test like start, run etc. should be processed under main motor is not started, in order to confirm everything is normal, then the starter can be used. Generally the start controller can be stopped automatically when something wrong, so it can be maintained without delay. Please pay special attention to checking the limit switch- SX1 or SX2 is working normally regularly (half a year), and checking the level of liquid resistor regularly (half a year), if it is too low (less than 50mm), the liquid resistance or water should be addedimmediately, in the process of adding, please prevent the flashing of liquid, otherwise the insulation will be damaged. Change the liquid resistance regularly (4 to 5 years), at the same time clean the polar plate and the insulated box, the specific techniques are as follow: firstly remove the oxide on the polar plate using diluted hydrochloric acid, then clean it with water; clean the box with water and dry it in the air first, then use PVC anti-corrosion glue coat the surface of polar plate several times, generally the box is not suitable for disassembly cleaning. Please check the condition and the contact of KM1, when the running current of main motor is too weak or the start liquid temperature is too high (more than 60 ) under the condition of starter empty-load test is normal; if the start current is too strong, pure water should be added because the liquid resistance is become weak.

Our old Greek customer, Evander, emailed me in November last year that he sent me a sample of hydraulic cartridge relief valve, and stressing that it was not his, but one of his partners, Ptolemy, and also attached Ptolemy's contact information. After receiving the sample and communicating with Ptolemy, we learned that the hydraulic cartridge relief valve was produced by a local cartridge valve manufacturer in Greek and installed in their hydraulic cylinder, which was unstable. Their engineers said that the root cause was the high back pressure of the hydraulic system and the insensitive opening of the hydraulic cartridge valve. We can't determine the hidden dangers of the hydraulic cartridge valve just according to the original sample. I suggested Evander sending us the video of abnormal hydraulic cylinder, the drawing of hydraulic cartridge valve, and the schematic of the system. After discussing, AAK engineers advised that the problem can only be solved by reducing the opening back pressure resistance of the hydraulic cartridge valve. Perhaps because of Evander's endorsement, Ptolemy paid the development fee on the second day. I have always believed that for industrial products such as hydraulic cartridge valves, it is difficult to get the order without trust. With trust and reliable manufacturing quality, it is easy to get the order. After 40 days, AAK sent 20 samples of hydraulic cartridge valve. Yesterday, Ptolemy emailed me that AAK hydraulic cartridge relief valve was used on the hydraulic cylinder. The prototype operated stably and the hydraulic cartridge valve opened sensitively. AAK hydraulic cartridge valve is stable and sensitive under high back pressure. We optimized the structure of the original hydraulic cartridge relief valve from 3 aspects. 1. The valve sleeve of the hydraulic cartridge relief valve has an oil inlet cavity, and the outer circle of the valve sleeve is provided with a plurality of annular through holes as oil outlet, and oblique holes are set to control the oil outlet. 2. The middle part of the main valve spool is provided with a small hole connecting the oil inlet cavity and the inclined hole, and the main valve spool can slide in the valve body to form a spring cavity that is relatively closed to the oil inlet cavity, and the spring cavity is equipped with a pressure regulating spring. 3. The left end of the valve body is installed with an adjustable rod that can be rotated and retracted and has a lock nut. The pressure regulating spring on the adjusting rod is connected to the main valve spool. The outer diameter of the right end of the valve body is provided with a sealing groove to place the sealing ring group. Two sealing grooves are set on the left side of the external thread of the valve body, and the sealing ring group is placed to seal the connection with the socket to prevent oil leakage. The optimized AAK hydraulic cartridge relief valve equalizes the pressure difference

Integrated Hydraulic Threaded Cartridge Valve, AAK replaced 3 HydraForce Valves with 1, which is simplified and cost effective Esteban is from a Spanish hydraulic equipment manufacturing company. Some time ago, their company customized a hydraulic cylinder for a customer. The hydraulic check valve, relief valve and electromagnetic unloading valve in the system are all standard parts from HydraForce. The customer is basically satisfied, but the cylinder structure is not very satisfactory, and the price has no advantage. Their engineer said that only by integrating the functions of hydraulic check valve, relief valve and electromagnetic unloading valve, and replacing them with only one hydraulic screw-in threaded cartridge valve, would the structure be simple and the cost be reduced. Esteban inquired about more than 10 hydraulic threaded cartridge valve manufacturers, but no result for a week. Esteban was worried. After browsing AAK website on Google, Esteban found that AAK had many cases of solving customer problems, and sent an email asking: Can AAK customize the multi-function hydraulic threaded cartridge valve to make the cylinder compact and reduce costs? After communication, it was learned that Esteban needed AAK to customize the hydraulic threaded cartridge valve to replace the functions of the 3 valves in the system. According to the hydraulic schematic diagram provided by Esteban, AAK engineers basically had the idea. Esteban asked for samples after knowing it. After 50 days, AAK sent 10 samples of hydraulic threaded cartridge valves. 1 month later, Esteban informed us by email that the customer was satisfied with the new structure of the oil cylinder, and should promote it first, and let us wait for the batch order. AAK used an integrated multi-function hydraulic threaded cartridge valve to replace the 3 valves of the original system, specifically as follows: 1. The valve housing is provided with a connecting valve hole, a working port of the oil cylinder, and a hydraulic control port, an oil inlet port and an oil return port. A check valve spool is set in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized and the check valve of the original structure is replaced. 2. The control check valve spool is separated from the working port, and the hydraulic control valve spool for unloading the oil inlet and the working port is connected. At the same time, the connection between the valve hole and the relief valve spool of the oil return port can also be disconnected. In this way, the overflow function is realized and the relief valve of the original structure is replaced. 3. The relief valve spool is equipped with connecting valve hole, oil return port and damping hole. One end of the damping hole is equipped with a unloading valve spool to control the opening and closing of the damping hole and the oil return port,
