If you wish to avoid temperature shock in hydraulic motors, the best thing you can do is to carefully learn what temperature shock really and why temperature shock happens in order for you to come up with the best solution available. A Temperature shock in hydraulic motors happens when there is a big difference between the temperatures of the hydraulic pump or motor and the temperature of the oil that is being fed or supplied to the motor. When this happens, there is a very rapid and localized heating on the internal parts of the hydraulic motor. The rapid, localized heating of the internal parts would expand at different rates which would cause interference between what should otherwise be internal parts that work perfectly in sync. This can cause problems that may cost you a lot of money to fix.
If this is the case, then how exactly does a temperature shock in a hydraulic motor happens? The only time that a temperature shock in a hydraulic motor happens is when there is a circuit in the hydraulic motor that is used for a long enough time to heat the oil or hydraulic liquid and then said liquid is transported to circuits that have been previously idling. What happens is that hot oil or hydraulic fluid is being pumped through or delivered into cold circuits of the hydraulic motor. This can cause certain damage to the entire hydraulic pump and can cause a lot of delays especially in construction projects which would cost a lot of money to fix. If so, then how can temperature shock in a hydraulic motor be avoided?
In order to avoid temperature shock in a hydraulic motor, the solution is really quite simple. In order for you to be sure that you are going to avoid a temperature shock in a hydraulic motor, you have to make sure that the motor of the case needs to be always be flushed; this means that there should be a circulation of oil and hydraulic fluid throughout the case of this hydraulic motor. This would help you make sure that the individual circuits in the hydraulic system stays in the same temperature as the oil and the hydraulic fluid that is moving all around it. Doing this would prevent temperature shock in a hydraulic motor; prevent any damage to the pump; prevent delays in the project and cost you money in repairs, maintenance of even delays. You need to carefully go over all the information you have gathered carefully before you fix or use hydraulic pumps.
