When replacing the hydraulic pump after the new should pay attention to what matters? Please follow the Yuhuan Paatz Hydraulic Power Machinery Co. Ltd. in the footsteps of a look at it! Mainly in the following aspects:
1, abnormal sound
Vibration or abnormal signal monitoring system, etc., must have a cause, an abnormal phenomenon was found, immediately got circuit diagram, a careful observation of abnormal phenomena caused by the error for the moment. Evaluate the need for parking. Such as pressure, load, temperature, time, start and stop when they contain may cause the abnormal phenomenon.
2, after the hydraulic pump starts, do not immediately add the load
The hydraulic pump must be carried out for a period of time without load (about 10-30 minutes), especially when the temperature is very low, the vehicle must be heated by the process, so that the hydraulic circuit cycle is normal, plus load, and confirm the operation.
3, observe the oil temperature changes
Pay attention to check the status of the maximum and minimum oil temperature changes, and found out the relationship of oil temperature and ambient temperature, so as to know the cooler capacity, whether the storage tank capacity and ambient conditions, conditions of use to cooperate with each other, troubleshooting cooling systems also have pattern.
4, pay attention to the noise of hydraulic pump
New hydraulic pump initial wear less, easy to be affected by bubbles and dust, high temperature lubrication or poor use conditions such as overload, will cause adverse consequences, so that the hydraulic pump out of the normal impact.
5, pay attention to check the display value of the meter class
Always observe the hydraulic circuit pressure gauge display value, pressure switch, light signal vibration situation and stability, as soon as possible to find whether the hydraulic circuit is normal.
6, pay attention to observe the action of the machine (for the modified pump)
Improper design of hydraulic circuit or poor manufacture of components is difficult to detect in the initial stage of operation. Therefore, special attention should be paid to the state of motion under various conditions of use.
7, pay attention to the adjustment of the valve
Full understanding of pressure control valve, flow control valve and direction control valve, the adjustment range and limit must pay special attention to, otherwise, adjustment errors not only damage to machinery, but also pose a threat to safety.
8. Check the filter status
The loop filter should regularly clean out, and check the filter of the adsorbed state and on-line dirt, analysis of quality, quantity and size, so the degree of pollution can be observed in the loop, even the basis to infer pollution source.
9. Regularly check the change of hydraulic oil
Check the deterioration, discoloration and contamination of hydraulic oil every one or two months to ensure that the hydraulic transmission medium is normal.
10, pay attention to the leakage of piping parts
Hydraulic device piping yes, after running for a period of time you can see whether the prosecution of oil leakage, piping loose.
11, the new machine running three months should pay attention to the operation
Machine operation in the new period, we should grasp the operating conditions such as inspection, maintenance parts, screws are loose, if there is abnormal increase in oil temperature, hydraulic oil is quickly degraded, check whether the conditions comply with the provisions of.
