Are you right in changing the hydraulic pump for construction machinery?
Due to the heavy workload and hard working environment of construction machinery, the fittings are extremely strict in the process of making and selecting. As the mainstay of the hydraulic pump, in the replacement of the details to pay attention to more, as the industry you, the replacement method standard?
Observation of changes in oil temperature changes: pay attention to check the status of the maximum and minimum oil temperature, 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.
Pay attention to the noise of hydraulic pump: the initial wear of the new hydraulic pump is less, it is easy to be affected by the bubbles and dust. When the lubrication is bad at high temperature or the use condition is too heavy, it will cause adverse consequences, and make the hydraulic pump produce abnormal influence.
Attention to the adjustment of the valve: fully understand the use of pressure control valve, flow control valve and directional control valve, the adjustment range and limit must pay special attention to, otherwise the adjustment error not only damage to machinery, but also pose a threat to safety.
After the hydraulic pump starts, don't immediately add the load: the hydraulic pump must be carried out for a period of time without load idling, especially when the temperature is very low, more through the warm car process, to ensure the normal circulation of the hydraulic circuit, and then to load, and confirm the operation.
Pay attention to check the display value of the meter class: observe the pressure loop display value of the hydraulic circuit at any time, the vibration situation and stability of the pressure switch light and so on, so as to find out whether the hydraulic circuit is functioning properly as soon as possible.
Attention should be paid to the movement of the machine: improper design of the hydraulic circuit or poor manufacture of the components, which are not easy to find in the initial stage of use, should pay special attention to the state of motion under various operating conditions.
Pay attention to the leakage of the piping part: whether the hydraulic device piping is good or not, after running for a period of time, it can be seen whether the oil leakage is checked and the piping is loose.
Check the state of the filter: the filter in the loop should be removed regularly, and check the state of the screen and the net of the adsorption of dirt, analysis of quality, quantity and size, so you can observe the degree of pollution in the loop, and even infer the source of pollution.
Regular inspection of hydraulic oil change: every one or two months to check and analyze the deterioration of hydraulic oil, discoloration and pollution degree changes, to ensure the normal hydraulic transmission medium.
Within three months of operation of the new machine note: the running status of 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.
When replacing the hydraulic pump in accordance with the instructions of the procedures and requirements, should also pay attention to the experience and correct, but also according to the specific circumstances of Shen north, it can prolong the service life of hydraulic pumps, mechanical machinery and equipment can also improve work efficiency.
