Jiaozuo brake

Instructions for use:

1. Installation test: First, check whether the thrust on the nameplate of the electric hydraulic thruster product matches the required force: remove oil stains on the motor and body surface, and check whether the push rod lifting is smooth. Unscrew the oil filling plug 5 (Figure 3) and oil level plug 3, and inject suitable and pure hydraulic oil until the screw hole 3 is reached. Then tighten plug 3 and plug 5. According to different ambient medium temperatures, it is recommended to follow Table 6 for hydraulic oil. The temperature of the surrounding medium is+45 ℃~+21 ℃+20 ℃~+0 ℃+0 ℃~-15 ℃~-15 ℃~-30 ℃ - below 30 ℃. 20 # mechanical oil GB443-64, 10 # transformer oil (freezing point -10 ℃) SYB1351-62, 25 # transformer oil (freezing point -25 ℃) SYB1351-62, instrument oil (freezing point -60 ℃), GB487-65, a mixture of alcohol and glycerol. It is recommended to use oil to connect the lower part of the hydraulic thruster with a pin, and connect the connecting rod of the crossbeam with a lever device with a pin. After testing whether the external power supply matches the motor nameplate, correctly connect the motor terminal to the external power supply. Connect the power supply and check whether the impeller operates flexibly and whether the push rod lifts smoothly. 2. Use and maintenance: check whether the electric hydraulic thruster works normally and whether there is oil leakage or oil seepage. A constant amount of oil should be maintained. But note that the oil level cannot be higher than the oil level plug. If it is higher than the oil level plug, there may be oil leakage at the push rod, motor, and cylinder head. Check the oil at least every six months. When the oil deteriorates or mixes with impurities, the oil should be changed when the viscosity increases. If the oil selection is not appropriate, a separate selection should be made. Check if the motor wiring is in good condition and if the protective device is appropriate and reliable.

Lubrication instruction table

Lubricating parts: The motor bearing at the hinge is limited to six months per week. Lubricating materials: calcium sodium based grease or 45-50 # engine oil: calcium sodium grease. Remarks

Fault analysis and troubleshooting

Fault location: Push rod spring motor, fatigue crack, abnormal noise during operation, failure analysis, troubleshooting, replacement

The internal wiring of the motor is incorrect, the voltage is internal, check the wiring system, and correct or change the loose fit of the electric stator, bearing wear and pressure, check and repair the stator, replace the bearing slide and shaft with severe wear, The force of the impeller roller key spring is too large, and the push rod is stuck. The network voltage is lower than 85% of the rated voltage. Severe oil leakage, insufficient oil level, high oil level, damage or unqualified bearing dirt, oil shortage, isolation ring, rolling element damage, overload work, or partial short circuit between individual silicon steel sheets under low pressure. Replace the sliding channel, Adjust the spring of the shaft or impeller to eliminate jamming, increase the voltage, supplement the oil, and allow the oil to drain. Replace the bearing or lubricating oil to eliminate dirt, add oil, and update the working status. If the measured voltage is lower than 10% of the rated voltage, stop working to remove burrs or other causes that cause short circuits. Afterwards, apply insulation paint to the repaired area. Check the current of each phase and eliminate "misconnected" phases, use indicator lights or high negative indicators to determine the location of damage and remove the damage.
