Description

[0001] The invention belongs to the technical field of full-digital integrated cylindrical valve fault processing, and in particular relates to a method for processing a full-digital integrated cylindrical valve lifting rod fracture. Background Art

[0002] At present, the fully digital integrated cylinder valve has been widely used in various high-head hydropower stations.

[0078] In one embodiment, removing the encoder and the stepper motor of the servomotor to be replaced includes:

[0079] Disconnect the control power supply of the servomotor to be replaced and the power supply of automation component 3 in the electrical control cabinet;

[0080] In the electrical control cabinet, disconnect the encoder power supply wiring of the servomotor to be replaced and make insulation wrapping;

[0081] Remove the encoder of the servomotor to be replaced, remove the stepper motor on the upper end of the fully digital cylinder of the servomotor to be replaced, and then place the removed stepper motor in a safe location and take protective measures to ensure that there is no foreign matter contacting the shafts at both ends of the stepper motor;

[0082] Remove the auxiliary equipment on the upper end of the relay to be replaced and make good insulation wrapping for the power supply;

[0083] Restore the removed stepper motor cable connection to ensure that the stepper motor can operate normally in the safe position, thereby achieving synchronous control;

[0084] Restore the Profibus communication wiring of the disassembled encoder. The encoder adopts the Profibus ring network communication mode to achieve displacement feedback.

[0085] In one embodiment, performing a single-action test on the servomotor to be replaced includes:

[0086] Restore the power supply of each control power supply and automation component 3 in the electrical control cabinet;

[0087] At the zero-point calibration interface of the hydraulic system, the servomotor of the small-stroke single-acting cylindrical valve is moved back and forth several times to ensure that the hydraulic system of the entire cylindrical valve operates normally after the stepper motor and encoder are removed, and the displacement of each servomotor fed back by the encoder is normal.

[0088] It should be noted that the small stroke refers to a relatively small movement displacement, which may specifically be 2 to 5 mm.

[0089] In one embodiment, setting the fault parameters includes:

[0090] Use the touch screen of the electrical control cabinet to enter the general parameter settings, and select "NO" for the option "Whether to prohibit the continued operation of the cylinder valve when the sensor fails", that is, the valve cylinder can continue to be operated when the sensor fails;

[0091] Close the cylinder valve test switch and ensure that the cylinder valve is in the necessary conditions for normal operation, for example, the guide vanes of the unit are fully closed, the volute is filled with water, the governor servo lock spindle is in the engaged position, etc.

[0092] In one embodiment, performing a small stroke test of a cylindrical valve includes:

[0093] In the electrical control cabinet, set the control mode of the cylindrical valve to "debugging" mode, and set the action displacement value of the cylindrical valve to operate the cylindrical valve with a small stroke;

[0094] After the cylindrical valve is stable, perform a small stroke action again to ensure that the remaining servomotors of the cylindrical valve that are not replaced operate normally;

[0095] Place the cartridge valve in the fully closed position.

[0096] It should be noted that the small stroke refers to a relatively small movement displacement, which may specifically be 2 to 5 mm.

[0097] In one embodiment, removing and replacing the lifting rod 1 of the servomotor to be replaced comprises:

[0098] Close the oil source of the switch chamber of the servomotor to be replaced. According to the installation requirements of the fully digital integrated cylindrical valve, disassemble the fully digital cylinder, servomotor and screw rod of the servomotor to be replaced in sequence and place them properly. Then enter the water guide mechanism to remove the super nut 2 at the lower end of the lifting rod 1 to be replaced.

[0099] Operate the cylindrical valve up and down in the electrical control cabinet to remove the lifting rod 1 to be replaced;

[0100] Replace the sealing device after cleaning the mechanical parts of the fully digital cylinder;

[0101] The lifting rod 1 is replaced and installed, and during the installation process of the lifting rod 1, the cylindrical valve is operated to move up and down by using the electrical control cabinet to adjust the verticality of the replaced lifting rod 1;

[0102] Tighten the super nut 2 to the lower end of the replaced lifting rod 1;

[0103] Reinstall the removed servomotor.

[0104] It should be noted that during the replacement of the lifting rod 1, it is necessary to ensure that the cylinder valve hydraulic system is automatically controlled and the hydraulic system is fault-free; maintaining the hydraulic system pressure near the rated pressure will more effectively ensure the convenience of the replacement of the lifting rod 1 and the stability of the hydraulic system.

[0105] In one embodiment, performing a pressure test on the upper and lower chambers of the replaced servomotor includes:

[0106] The cylinder valve is in the fully open position to conduct pressure and pressure holding tests on the upper and lower chambers of the replaced servomotor to ensure that the replaced servomotor is well sealed and avoid oil leakage between the upper and lower chambers of the replaced servomotor due to seal damage, thereby preventing deviation in the control of the cylinder valve;

[0107] After the pressure test and pressure holding test are completed and all data are qualified, install the removed full digital cylinder.

[0108] In one embodiment, performing a full stroke test of a cartridge valve includes:

[0109] Restore the installation and wiring of automation element 3 on the servomotor, restore the installation and wiring of the stepper motor and encoder on the replaced servomotor, restore the installation of auxiliary equipment on the replaced servomotor, restore the parameter settings of the electrical control cabinet, restore the power wiring of the encoder of the replaced servomotor in the electrical control cabinet, and restore the power circuit breaker;

[0110] Since the encoder value after recovery may be much higher than the displacement value of other relays, the cylindrical valve control system will report signals such as "cylindrical valve out of step" and "cylindrical valve stuck", so it is necessary to preliminarily calibrate the cylindrical valve zero point or cylindrical valve full point according to the cylindrical valve mechanical full open position or full closed position under the premise of ensuring the balance of the cylindrical valve;

[0111] Calibrate the sensor of the cylindrical valve; due to the sudden change of the sensor displacement value, the system will judge that the cylindrical valve has slipped abnormally and alarm, so the fault needs to be restored;

[0112] According to the installation and maintenance design requirements of the fully digital integrated cylindrical valve, in the "debugging" mode, the cylindrical valve is repeatedly actuated with a small stroke for several times; if a step-out alarm occurs, electrical correction is used; if a jam signal occurs in the cylindrical valve, the position of the cylinder is corrected through mechanical correction; if there is no abnormality, the cylindrical valve is actuated with a gradually increased stroke until the cylindrical valve can be actuated with a full stroke once.

[0113] In one embodiment, calibrating the cartridge valve zero point and the cartridge valve full point includes:

[0114] After the hydraulic system returns to rated pressure, calibrate the full point of the cylinder valve to ensure the balance of the cylinder valve;

[0115] Then calibrate the zero point of the cylinder valve to ensure that the mechanical zero point, hydraulic zero point and electrical zero point are consistent.

[0116] It should be noted that the action of the cylinder valve is based on the zero point of the cylinder valve, which can ensure the sealing of the cylinder body after the cylinder valve is fully closed, thereby ensuring that there is no leakage in the water guiding mechanism, thereby preventing the unit from creeping or cavitation of the water guiding mechanism due to leakage in the water guiding mechanism.

[0117] In one embodiment, measuring the cartridge valve guide clearance includes:

[0118] Measure the guide clearance when the cylindrical valve is fully closed, half open and fully open respectively;.

[0119] In one embodiment, performing a full-operation operation test of a cylindrical valve in a waterless state includes:

[0120] Carry out full opening, full closing and emergency closing tests of the cylinder valve in the electrical control cabinet;

[0121] The monitoring system is used to conduct full-open, full-close and emergency-close tests on the cylinder valve.

[0122] In addition, in the step of calibrating the zero point and full point of the cylinder valve, relevant test data records need to be kept; in the step of measuring the guide clearance of the cylinder valve, measurement data records need to be kept; in the step of conducting the full-operating condition action test of the cylinder valve in the waterless state, the full open, full close and emergency closing times need to be recorded; in the step of writing the processing report, the processing report includes all maintenance processes, test data, measurement data, and full open, full close and emergency closing times, etc.

[0123] To sum up, the method for handling the fracture of the lifting rod of the fully digital integrated cylinder valve gives full play to the advantages of high integration and reliability of the fully digital integrated cylinder valve. It can quickly handle the fracture fault of the cylinder valve lifting rod 1 without overhauling the unit and lifting out the cylinder valve body, which can effectively shorten the maintenance period of the unit and prevent the further expansion of the unit failure caused by the fracture of the cylinder valve lifting rod 1, providing a reliable guarantee for the safe and reliable operation of the unit, so as to effectively prevent flooding accidents, major casualties and damage to equipment and facilities.
