Daily inspection of dc hydraulic power unit
The maximum working pressure of the hydraulic pump of the hydraulic power unit means that the working pressure of the hydraulic pump increases with the increase of the external load.When the working pressure increases to the allowable strength of the hydraulic pump itself and the maximum allowable leakage, the working pressure of the hydraulic pump no longer increases, and the working pressure of the hydraulic pump is the highest working pressure.
The rated pressure of the hydraulic pump is the maximum working pressure allowed during the operation of the hydraulic pump, that is, the pressure indicated on the nameplate of the hydraulic pump or the product sample.
1) circuit inspection: the power of the dc hydraulic power unit comes from the battery of the vehicle system, and different motors are used according to different voltages.Since the dc motor circuits of hydraulic power units are connected in various ways on the market, it is necessary to follow the manufacturer's circuit strictly.Link drawings to connect.It is important to note that since the power unit is not a rainproof motor, it is usually necessary to check that the wiring is stable and that the motor is waterproofed.Daily inspection of dc hydraulic power unit
2) oil quality inspection, using hydraulic oil for more than 10 months.Please clean the oil tank carefully when replacing the hydraulic oil.If the hydraulic power unit linkage is simple, it is recommended to separate the fuel tank and use a dough to clean the impurities.
Hydraulic power unit is the most critical part of hydraulic elevator equipment.How to carry out professional maintenance in daily use is a problem that needs attention, especially for the international brand hydraulic pump station, need more attention and good use.Each link can reduce the damage caused by artificial equipment.
Hydraulic pump station is an important part of the hydraulic system, so it is also known as the power unit.It provides the working medium with certain pressure and flow rate for the hydraulic system.The hydraulic actuator can be directly controlled by installing the necessary hydraulic valve on the hydraulic pump station.Don't underestimate this small pump station, which is the core of the entire lifting platform.The pump and fuel tank constitute the power unit.It can lift lift loads of hundreds of tons by tens of meters.
In the analysis and description of theoretical tasks, theoretical operating conditions in block diagram scintillation equipment are usually selected.The hollow arrow represents the signal flow, while the solid arrow represents the energy flow.
The actions in the sub-hydraulic loop are sequential - control element reversing and spring return, component extension and retraction, and relief valve opening and closing.The implementation of components and control components is demonstrated based on the corresponding circuit diagram notation, which is also prepared to introduce circuit diagram notation.
According to the system task principle, you can number all loops in turn.If the first implementation component number is 0, the associated control component identifier is 1. If the component identifier corresponding to the implementation component extension is even, the component identifier corresponding to the implementation component undo is odd.
