Application of solenoid valve and troubleshooting method
What is solenoid valve in the dry mortar wall putty powder complete production line
The solenoid valve is widely used in the dry mortar wall putty powder complete production line. The electrical control system is a set of very rigorous and precise equipment. Once an error occurs, the entire set equipment may not be operated normally and affecting the output of dry mortar and putty powder. Let's introduce the application and troubleshooting methods of solenoid valve in wall dry mortar and putty powder complete equipment.
Working principle of solenoid valve in the dry mortar wall putty powder complete production line
First of all, we need to understand the working principle of the solenoid valve in the putty powder dry mortar equipment, and find out the problems of the logic valve and consider it. It is time and cost spending if redesign he logic valve, For time and cost saving, the better solution is "extra-junction" method to solve this problem, that is without changing the structure of the logic valve, install three-way joints on the valve's 6 control ports, and then lead out 6 pipelines and connect two groups three-way check valves respectively, and then connect the two pipelines after passing through the three-way check valves to two unloading solenoid valves. The two unloading solenoid valves and the unloading solenoid valves on the logic valve are overloaded. The unloading solenoid valve and the overhead unloading solenoid valve have the same function. According to the schematic diagram, before the torque limiter provides an electrical signal to the unloading solenoid valve, the unloading solenoid valve is normally off, that is, the unloading circuit is disconnected, and once the torque limiter provides an electrical signal to it, the unloading solenoid valve is energized, reversing, and the unloading circuit is connected. For this purpose, the pipeline on one side of the logic valve is disconnected, and then it is found that when the torque limiter does not issue a command, the overload unloading electromagnetic The valve Y1 has no electricity, the solenoid valve has no direction change, and no pressure oil flows out. When the machine enters the overload condition, the valve is energized and hydraulic oil flows out of the pipeline. Therefore, the purpose of checking the circuit from both the circuit and the liquid circuit is to check whether the torque limiter and limit switch can transmit the electrical signal to the unloading solenoid valve while providing the warning signal of the panel indicator. If it can, the unloading circuit will be connected to realize safe unloading, otherwise, safe unloading will fail.
Regular inspection for solenoice valve in complete set of putty powder and dry mortar equipment
Secondly, the regular inspection of the solenoid valve in complete set of putty powder and dry mortar equipment is very important. After checking the circuit and then check the fluid circuit. First, check the wiring and there is no error. Finally, focus on the logic valve and check valve in the logic valve. The spring is harder or the diameter in the valve is small, which makes the back pressure of the unloading oil circuit larger, which leads to the unblocking of the unloading oil circuit. The unloading problem is so in the alarm state, the pressure of the corresponding port of the action is measured, and the pressure is found to be About 1MPA, the main valve only needs a pilot pressure of about 0.6MPA to open, which confirms the accuracy of the doubt. It is precisely because of the large back pressure in the logic valve that the unloading problem is caused. This shows that the logic command program issued by the torque limiter is normal, and the operation of the unloading solenoid valve is also normal. The limit switch that controls the over-elevation unloading and the over-elevation unloading solenoid valve are also working normally when checked. , The possibility of circuit failure is ruled out. Hammer sander. Moreover, the two unloading solenoid valves and the two unloading solenoid valves on the logic valve form a parallel relationship in the circuit and the liquid circuit, forming two sets of solenoid valve groups with the same protection function. Once the torque limiter or limiter The switch sends out an electric signal, and the parallel unloading solenoid valve group with the same function will change direction at the same time to ensure normal unloading and quickly block the main oil circuit, so that the putty powder complete set of equipment cannot be inherited under dangerous conditions such as overload or over-elevation. produce.
The solenoid valve plays a very important role in the complete set of putty powder dry mortar equipment. Therefore, we should do regular inspection and maintenance work to ensure the normal operation of the equipment.
