When the liquid enters the high pressure zone of low pressure (pressure drop) to do useful work, heat. This law of physics can be very useful to understand the flow chaser when armed with an infrared thermometer or a heat exchanger. Simply put, it means that if a portion of hydraulic filter is many degrees warmer than the rest of the system, it is likely that this is a different source of internal bleeding.
To return to the multi-pump scoop above example using a heat exchanger to measure the relative temperature of the well pump # 2 cases, relief valve, etc. can greatly help the process logic flow chaser warned of the elimination.
Photoelectric tachometer
The flow rate and speed of a rotary actuator (motor) is measured in RPM. Thus, as the stopwatch is a photoelectric tachometer Another handy tool when tracing missing flux.
For a simple example, consider a unit hydraulic troubleshooting, jet air heat exchanger circuit see 1. One of the variables that determine the effectiveness of cooling is the fan speed. If the fan speed decreases, the result of airflow through the central interchange, and consequently, heat exchanger is reduced.
A photoelectric tachometer can be used to monitor the RPM of the fan and confirm this either way. If the fan speed is slower than it should be the component responsible for the escape movement (pump fan, fan motor, bypass valve or safety valve), then determined using a logical process disposal. This requires action at the circuit-see Figure 2 The bypass valve can be eliminated as a suspect, install a ball valve, as shown, then check the engine fan again with the valve closed. Then, the mixing pump actually be tested and flow control safety valve confirmed by installing a pressure gauge and needle valve as shown in Figure 2
