D1VW008CNJW91 Parker solenoid valve installation instructions.
Parker solenoid valve failure will directly affect the action of the switching valve and regulating valve, common faults are solenoid valve does not operate, should be investigated from the following aspects:.
1, the solenoid valve terminal loose or wire off, solenoid valve shall not power, can tighten the wire.
2, solenoid valve coil burned, can remove the solenoid valve wiring, measured with a multimeter, if the open circuit, the solenoid valve coil burned. Reasons have coil moisture, caused by insulation is not good and magnetic leakage, resulting in excessive current in the coil and burned, so to prevent rain into the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the number of turns of the coil is too small, the suction force is not enough can also make the coil burned. Emergency treatment, the coil on the manual button from the normal operation of the "0" position to "1" position, making the valve open.
3, solenoid valve stuck: solenoid valve slide valve sleeve and spool clearance is very small (less than 0.008mm), generally single-piece assembly, when there are mechanical impurities into the lubricant or too little, it is easy to get stuck. Treatment can be used wire from the head of a small hole to poke, so that it pops back. The fundamental solution is to dismantle the solenoid valve, take out the spool and spool sleeve, and clean it with CCI4, so that the spool moves flexibly in the valve sleeve. Disassembly should pay attention to the assembly order of components and external wiring location, in order to reassemble and wiring correctly, but also to check whether the oil mist spray hole is blocked, whether the lubricant is sufficient.
4, air leakage: air leakage will cause insufficient air pressure, making it difficult to open and close the mandatory valve, the reason is that the sealing gasket is damaged or the slide valve wear and tear caused by several cavities to run out of air. In dealing with the switching system solenoid valve failure, should choose the appropriate time, such as the solenoid valve is in the loss of power to deal with, if in a switching gap processing is not complete, can be suspended from the switching system, from the processing.
