What problems should be paid attention to during the process of installing the hydraulic oil pump on the baler?
In the process of installing the hydraulic oil pump of the waste paper baler, in order to prevent debris from falling into the machine, all holes of the unit should be covered, and the unit should be placed on the foundation with anchor bolts, between the base and the foundation, Use a pair of wedge pads for calibration. Correct the concentricity of the pump shaft and the motor shaft. On the outer circle of the coupling shaft, the allowable deviation is 0.1 mm; the gap between the two coupling planes should be 2 to 4 mm, and the gap should be uniform and allowable 0.3 mm. After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling again and check the concentric squares of the shaft again. After the unit is actually tested for 2 to 3 hours, make a final inspection. If there is no bad phenomenon, then The installation is considered qualified.
Matters needing attention in the process of installing the hydraulic oil pump of the waste paper baler:
1. The quality of the oil pump installation has a very important impact on the smooth operation and service life of the pump, so the installation and correction work must be carried out carefully and not rashly. The support or base of the hydraulic pump must be strong and firm, and the pump shaft of the hydraulic pump must be well aligned with the motor.
2. The installation height, length and diameter of the suction pipe of the oil pump should meet the calculated value, strive to be short, reduce unnecessary losses (such as elbows, etc.); and ensure that the pump does not exceed its allowable cavitation allowance when it is working. The inner diameter of the oil suction pipe should not be less than the specified requirements. The suction pipe should not be too long. The 90-degree bend should not exceed two. It is best to connect with the oil pump inlet with a soft short connection. The installation height of the oil pump should be such that the hydraulic oil can flow to the suction port of the oil pump.
3. The suction and discharge pipelines of the oil pump should have supports, which are not allowed to bear the load of the pipelines.
4. The place where the oil pump is installed should be spacious enough to facilitate maintenance work.
After installing the hydraulic oil pump of the waste paper baler, check the temperature and vibration of the bearing during the test run as follows:
Loosen the coupling, place a level meter on the pump shaft and base of the electric oil pump, adjust the wedge pad to correct the unit level, and properly tighten the anchor bolts to prevent it from moving.
In order to prevent debris in the pipeline from entering the pump, a filter should be installed in the pump glue for the newly installed pipeline, and the effective section should be 2 to 3 times larger than the section of the suction pipe.
