What should be paid attention to in the new hydraulic pump
New installation or new start equipment need to pay attention to more matters, this relates to the equipment after the use and maintenance of life, so in the new machine start in addition to the instructions in accordance with the norms of operation, on the use of hydraulic pumps, the following points are also not to be ignored.
Pay attention to whether there is any abnormal phenomenon
Abnormal sound and vibration monitoring system or abnormal, 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. Evaluation requires no parking treatment. Such as pressure, load, temperature, time, start, because all the possible fault stop. It should be discussed and discussed in a timely manner.
Observe the change of oil temperature
Pay attention to check the maximum and minimum oil temperature changes, and find out the relationship between the oil temperature and the ambient temperature, so as to know whether the cooler capacity, oil tank capacity and the surrounding conditions, the use of conditions to cooperate with each other, the cooling system troubleshooting also has traces.
Do not immediately load the hydraulic pump after starting
Hydraulic pump must be carried out for a period of no load Idling (about 10 minutes ~30 minutes) after starting, especially when the temperature is very low, more through the warm car process, make the hydraulic circuit cycle normal, and then load, and confirm the operation.
Pay attention to the noise of hydraulic pump
The new hydraulic pump has low initial wear, easy to be affected by bubbles and dust, bad lubrication at high temperature or excessive use conditions, etc., will cause adverse consequences, making the hydraulic pump abnormal impact.
Pay attention to checking the display value of the meter class
At any time observe the hydraulic circuit of the pressure gauge display value, pressure switch, light and other vibration conditions and stability, in order to find the hydraulic circuit as soon as possible the role of normal.
Pay attention to the adjustment in each valve
Fully understand the use of pressure control valve, flow control valve and directional control valve, must pay special attention to the scope and limit of adjustment, otherwise the adjustment error not only damage the machine, but also pose a threat to safety.
Check the status of the filter
The filter in the circuit should be removed and cleaned regularly, and the status of the filter screen and the dirt adsorbed on the net should be checked. The quality, quantity and size of the filter can be analyzed, so that the pollution level in the circuit can be observed, and the source of pollution can be deduced.
Pay attention to the action of the machine (for refitting pump)
Improper design of hydraulic circuit or poor manufacture of components is difficult to find in the initial stage of operation, so special attention should be paid to the action state under various operating conditions.
Pay attention to piping leakage
Hydraulic device piping is good or not, after running for a period of time you can see whether the oil leak inspection, piping loose.
Regularly check the change of hydraulic oil
The deterioration, discoloration and contamination degree of hydraulic oil are checked and analyzed every one or two months to ensure the normal hydraulic transmission medium.
Attention should be paid to the operation of the three months after the operation of the new machine
During the operation of the new machine, the running condition should be checked, such as the maintenance of the parts, the looseness of the screw, the abnormal increase of the oil temperature, the deterioration of the hydraulic oil, and the check of the conditions for the use of the oil.
Wonderful recommendation:
