If automatic washing machine at home with the turn in the barrel, one-way forward / reverse different sound, washing dehydration no action, running different sound and a series of problems, mostly because the clutch is faulty, if you know some knowledge of electrical and mechanical aspects can be based on common faults mentioned in this article for maintenance and replacement, if you do not know to find the best professionals for maintenance.
Fault: When washing bucket inside with turn
A: When washing the barrels with a clockwise turn
Cause Analysis: ① lever coupling plate collide with traction, braking zone is not completely hold of brakes. ② clutch operation after a certain period, with badly worn brakes, friction is reduced. ③ there is oil on the brakes.
Repair method: ① connecting plate and lever position adjustment. ② ③ analysis should replace the brake with oil source, if the brakes itself is dirty, replace the brake disc brakes and clean. If the shaft assembly leakage, indicating the brakes and clutch shaft riveted joints cracked or damaged, you need to replace the clutch.
B: When washing the barrels with counterclockwise rotation
Cause Analysis: ① way tie between the bearing and the shaft dewatering loose, slipping phenomenon, with loose-way between the bearing and the housing ②, slipping phenomenon, ③ bad way bearing.
Repair: Replace the clutch.
Failure II: Washing Washing way forward / reverse different sound
Cause Analysis: ① When washing, ratchet assembly is not open certain margin, so that can not hold clutch spring rotate freely within the ratchet. ② ratchet bore contraction. ③ slip-way bearing in the housing.
Maintenance: Check the fork assembly in washing initial state deformation, deformation Ruoyi replacement fork assembly; if there is no deformation, compared with ratchet bore contraction, replacement ratchet assembly. If for reasons ③, when washing will be accompanied with the transfer of the phenomenon.
Failure three: No action dehydration
Analysis: ① lever and pull the gap between the coupling plate is too large not completely out of the ratchet pawl. ② fork adjustment screw and lever assembly gap is too large, leading to brake with the fork assembly does not fully open. ③ ④ ratchet hold spring break other reasons lead to bearing damage due to leaks, rust and brake disc brakes with bite.
Repair method: ① adjustment lever and the connecting plate to the proper position. ② adjustment lever adjusting screw and the gap between 0 ~ 0.2mm. ③ replacement ratchet hold spring assembly. ④ replace the clutch.
Failure four: Washing no action
Cause Analysis: ① Rotate the pulley, if not rotate, it is a planetary gear stuck internal corrosion, or oil between the copper lining and shaft rust stuck. ② clutch can operate normally, check the impeller wear inserts. ③ ④ fracture belt worn motor failure.
Repair method: ① replacement impeller clutch ② ③ replacement belt replacement. ④ replace the motor
Failure Friday: no dehydration
Cause Analysis: ① ② bearing rust belt failure ratchet ③ open, square hole damaged pulley locking nut loose. ④ ratchet hold spring slipping. ⑤ lock brakes with brake discs. ⑥ electrical fault.
Repair method: ① ② replace the V-belt replacement clutch repair ③ ④ corresponding clutch outer diameter smaller or larger inner diameter ratchet hold spring - Replace clutch or hold hold spring in spring or transferred impurities. Replace the ratchet assembly. ⑤ drain state, clockwise rotation is forced dehydration barrel can be rotated. Can not clean the brakes. One-way bearing upside? ⑥ find electrical reasons.
Failure Six: leak (excluding the tub is leaking)
Cause Analysis: ① main seal lip wear rupture, prolonged leakage can cause clutch bearings, brakes and other components rust, can not be dehydrated normal clutch. ② small oil seal lip wear rupture, the water will seep inside the clutch shaft assembly, leading to planetary gears, bushings and other corrosion, clutch not properly washed.
Repair method: Exclude the tub, drain leakage factors and other components to determine the clutch after leaking, replace the clutch.
Failure Seven: running different sound
A: washing different sound
Cause Analysis: ① planetary gear and ring gear involute not fully fit, or too little fuel injection internal gear, will be issued at the time of the operation, "Gululu" sound. ② washing shaft and the shaft axis is not a straight line, resulting in discontinuity bushings, rear axle lining wear long out of round. Rotate the pulley at this time there will be significant rotation is not smooth feeling. (Late) ③ Washing insert wear, loose fit.
Maintenance: First remove Washing Washing exclude different sound, the second motor exclude different sound. ① ② ③ replace the impeller clutch replacement.
B: Dehydration different sound (exclude boom, such as the Department of the tub is installed issues)
Cause Analysis: ① When the composite bearing clearance uneven operation will be issued bearing different sound when running. In manual rotation, there is the feeling of catching. ② copper lining wear: hand and hold the pulley runout feel great.
Repair method: the exclusion of other department boom, the tub, motors and other equipment problems, identify different sound for the clutch. ① bearing ring, replace the clutch. ② replace the clutch.
The above is all automatic washing machine clutch common faults and maintenance methods, if there is a fault recommend replacement of the clutch. |
