In the long-term operation of the small hydraulic baler, failures sometimes occur. In order to ensure the normal use of the baler and the smooth production of the enterprise, it is particularly important to disassemble and repair the failed small hydraulic baler in time. In order to improve the failure maintenance rate of the small hydraulic baler and reduce unnecessary maintenance costs, Nick Machinery briefly summarizes the following points that need to be paid attention to when disassembling the hydraulic baler.
1. Advocate marking and keep simple disassembly and assembly records
5. Check whether the connecting bolts between the oil pipe of the straw silage baler and the oil cylinder are loose (to prevent oil leakage and reduce pressure).
6. Check whether there is any leakage in the oil cylinder and the oil pipe.
4. When cleaning the metal woven square mesh filter element, you can use a brush to scrub in gasoline. And clean high-precision filter elements. You need to use ultra-clean cleaning fluid or cleaning agent.
5. When the oil filter pressure difference indicator of the hydraulic baler displays a red signal, clean or replace the filter element in time.
2. Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing shocks, resulting in noise and vibration.
3. Due to mechanical vibration, such as slender tubing, many elbows without being fixed, it is easy to cause tube shaking when oil flows through, especially when the flow rate is high; the rotating part of the motor and hydraulic pump is unbalanced, or is installed Poor time alignment or loose couplings can cause vibration and noise.2. Short circuit protection: The air switch is a switch that trips as long as there is a short circuit and the switch forms a loop.
3. The principle of the air switch is that when the line is short-circuited or severely overloaded, the short-circuit current exceeds the instantaneous tripping setting current value, and the electromagnetic tripping device generates enough suction force to attract the armature and hit the lever to make the hook around the shaft seat Rotate upwards to release the lock, and the lock breaks the three main contacts under the action of the reaction spring to cut off the power supply.
4. Loss of voltage protection Undervoltage protection: The coil of the contactor is generally connected in parallel with the electrical equipment. If there is a voltage loss or undervoltage, the electrical equipment will be burnt due to lack of phase, and the contactor has loss of voltage and undervoltage During protection, if the voltage is not enough or the phase is missing, the contactor will trip and use electrical equipment to disconnect. So as to protect the electrical equipment from burning due to lack of phase or undervoltage.
Therefore, the electrical self-locking circuit of the hydraulic baler is particularly important and requires key protection.
