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.

After the Hitachi ex100 hydraulic pump is started, it must be idling without load for a period of time (about 10 minutes to 30 minutes), especially when the temperature is very low, it must go through the warm-up process to make the hydraulic circuit circulate normally and add preload, and confirm the operation status.
(5) Observe the change of oil temperature
Pay attention to check the changes of the maximum and minimum oil temperature, and find out the relationship between the oil temperature and the external ambient temperature, so as to know whether the capacity of the cooler and the capacity of the oil storage tank are compatible with the surrounding conditions and the conditions of use, and the troubleshooting of the cooling system is also possible. Traces to follow.
(6) Pay attention to the noise of the Hitachi ex100 hydraulic pump
The new hydraulic pump has less initial wear and is easily affected by air bubbles and dust. Poor lubrication at high temperature or overloaded operating conditions will cause adverse consequences and cause abnormal effects on the hydraulic pump.
