It is standby to be usually in shutdown status.In winter, particularly severe cold area, oil temperature is relatively low, and the oil liquid temperature inside hydraulic system is low, glues
Degree is big, poor mobile performance, and working efficiency is also poor, and work is run by force under this environment, may result in hydraulic system member device
The failure of part is damaged or even is scrapped.Traditional industrial refrigeration machine does not heat and constant temperature system.
Therefore the stability of industrial constant-temperature machine directly influences the working condition of machinery equipment, in traditional industrial constant-temperature machine
When fluid pressure is excessive, directly result in that pressure in heat exchanger is excessive to damage radiator.General radiator is to radiate
For the collecting tank of device all there are one the capacity of fixed proportion, fluid has certain big resistance by radiator heat-dissipation channel interior.It
Amount of liquid storage it is smaller, do not buffer, encountering the temperature difference is big, low temperature environment, flow are uneven, has certain viscosity liquid, having punching
It hits under the fluid situations of power, the pressure of radiator heat-dissipation channel interior also increases therewith, is especially having impact force and viscosity to compare
In the case of big fluid, since fluid is in the resistance of channel interior, fluid is prevented to be allowed to from running through inside radiator passage
Pressure increases, and more than the highest operating pressure of radiator, radiator is easy to damage, scrap.
