hitachi ex100 hydraulic pump

Excavator Hitachi ex100 hydraulic pump installation precautions (1) Ensure that the hydraulic oil is very clean The hydraulic oil directly enters the Hitachi ex100 hydraulic pump. If there are impurities in the hydraulic oil, the structures such as the plunger and the distribution plate will be worn, causing damage to the hydraulic pump, and even the hydraulic pump will be scrapped! Therefore, the hydraulic oil filter must be a genuine filter. Generally, the higher the density of the filter, the better the quality of the filter! (2) After the Hitachi ex100 hydraulic pump is installed, there is no hydraulic oil, and it is strictly started. It is necessary to add hydraulic oil to the oil return pipe. (3) Pay attention to the discovery of abnormal phenomena at any time Abnormal sounds, vibrations, or abnormal signals of the monitoring system must have their reasons. When an abnormal phenomenon is found, immediately find the circuit diagram, follow the diagram to find out, and carefully observe whether the abnormal phenomenon is caused by a temporary error. Assess the need for parking. For example, pressure, load, temperature, time, start-up, and stop all include the reasons that may cause abnormal phenomena. Usually, it should be analyzed and discussed item by item.
