1. How to detect the hydraulic pump flow rate of Kubota 163-5 excavator
To detect the hydraulic pump flow rate of Kubota KX163-5 excavator, a professional hydraulic flowmeter needs to be used for actual measurement, with a standard rated flow rate of about 2 × 118 L/min. 1. Prepare a hydraulic flow meter with a suitable range (recommended range 0-300 L/min), wrench, seal, cloth, and oil pan. Ensure that the equipment is parked on a flat and hard surface, the engine is turned off, the operating handle is locked, and the residual pressure in the hydraulic system is released. 2. Connect the flow meter and find the high-pressure pipeline at the outlet of the main hydraulic pump (A6VM series double plunger pump). Slowly loosen the connector and connect the flow meter in series to the circuit, ensuring that all connections are firm and well sealed, and preventing air from entering the system. Measure and record the engine start, maintain idle speed (about 1000 rpm), and preheat the hydraulic oil to 50 ± 5 ℃. Then increase the engine speed to the rated high idle (approximately 2150 rpm) and operate the working device to bring the pump to its maximum displacement state. After the reading of the flowmeter is stable, record the value. Multiple measurements should be taken at different speeds (idle, half throttle, high idle) and different loads (no load, light load) to obtain the average value. 4. Data comparison and analysis. The rated flow standard value of the main pump of the Kubota KX163-5 excavator is approximately 118 liters per minute (a total of 236 L/min). Compare the measured average value with this standard. If the deviation exceeds ± 10% (such as below 106 L/min or above 130 L/min), it indicates that the pum
2. Oil cylinder leakage detection methods
Oil cylinder leakage detection methods include pressurization method, flowmeter method, tracer detection, pressure attenuation method, ultrasonic detection technology, temperature monitoring, and comparative testing method.
. 1. Pressurization method: Connect the oil port of the oil cylinder with a metal tube, manually operate to fully extend the piston rod, seal the rodless chamber interface, and connect the rodless chamber interface to the manual hydraulic pump to pressurize to the rated pressure. Observe the pressure gauge value for any changes. If it drops by more than 5% within ten minutes, it indicates that there is a problem with the piston seal. 2. Flow meter method: Install a high-precision flow meter in the oil cylinder return line, make the piston rod move back and forth, and continue to supply oil when the piston moves to the end of the stroke. Measure the flow rate of the return line, which is the internal leakage rate. When selecting a flow meter, fill the range of Mu Sen Yi. 3. Tracer detection: Add fluorescent dye to the hydraulic oil in proportion, irradiate the suspicious area with ultraviolet light, which is sensitive to micro leakage, but needs to be teste
