Keep your strange scene: strange tone, vibration or strange signal supervision system, to its cause, a strange scene, immediately got circuit diagram, to inspect whether accidentally strange scene was caused by a fallacy. No parking is required for the assessment. Such as pressure, temperature, load, time, start, stop all contained a cause might produce strange sights. The study should be comprehensive research one by one.
No load is added immediately after starting the hydraulic pump. After starting, the hydraulic pump must be carried out for a period of time without load and idle (about 10 seconds ~30 seconds). Especially when the temperature is very low, it is necessary to turn the hydraulic circuit back to malfunction and add load to the inside of the warm car, and confirm the operation.
Inspect the temperature change: careful review of the maximum and minimum oil temperature changes, and find out the relationship between oil and soft conditions of heat, so the ability to know is quantitative, quantitative reservoir ice and ambient conditions, the use of conditions with each other, traceable to freezing system troubleshooting only.
Watch music: hydraulic pump hydraulic pump new year wear less susceptible to unwarranted bubbles and dust, low temperature time smooth and bad or application conditions over Holland, will lead to adverse antecedents, the hydraulic pump to recover the unwarranted abnormal.
Careful examination indicates the meter class value: the value that the pressure gauge inspection at any time of the hydraulic circuit, pressure switch signals the vibration situation and peace, in order to find the effect of hydraulic circuit is abnormal.
Observe the mechanical action status (about refitted pump): the design of the hydraulic circuit is not well designed or the components are not well built, so it is not easy to find in the initial stage of operation. Therefore, we should pay particular attention to the behavior state displayed under the operation conditions of all nationalities.
Pay attention to the adjustment in each pump: fully understand the pressure control valve, flow control valve and position control valve. We must pay special attention to adjusting the scale and limit. Otherwise, we should not adjust the falsehood, not only damage the machinery, but also form a threat to insurance.
Review the state of filter: the filter in the loop should be regularly kept in check, and check the state of the filter net and the contaminants adsorbed on the network. The quality, quality and size of the filter can be used to check the purification level in the inspection loop, and even inferences the origin of purification.
Regular review of the change of hydraulic oil: every one or two months, we review the change of the deterioration level of the comprehensive hydraulic oil, color change and purification level, so as to ensure the malformation of the hydraulic transmission media.
The control section revealed the situation: the hydraulic installation pipe is good or not, after a period of time, we can see whether the prosecutor is leaking and the pipe is loose.
Three months should be the operation of the new machine operation: during the new machine operation, should be in the operation of examination, such as mechanical maintenance, screws are loose, if there is no abnormal temperature rise, hydraulic oil is quickly degraded, conditions are consistent with the procedures of examination and application.
