Abstract
The invention relates to an operating method of a hydraulic heat-exchange system of a hydraulic bypass provided with a piston type pressure release valve. The hydraulic heat-exchange system of the hydraulic bypass provided with the piston type pressure release valve comprises a device heating source, a radiator and a liquid storage tank which are cyclically connected in series through oil ways. A cooling fan is arranged at one side of the radiator. The piston type pressure release valve is arranged on the oil way connected with the two ends of the radiator in parallel. When the radiator is blocked or the inner pressure of the radiator is too high, a hydraulic main path is obstructed, the pressure at one end of the piston type pressure release valve is greater than that at the other end, fluid pushes a partition plate to move to the low pressure side, and the pressure is released; and when the pressures at the two sides of the partition plate are equal, a piston restores to the original position, and the hydraulic main path is unobstructed again. The operating method of the hydraulic heat-exchange system of the hydraulic bypass provided with the piston type pressure release valve has the advantages of being high in reliability, not prone to damage, and capable of guaranteeing stable operation of the system.
Description
Technical field
The present invention relates to a kind of method of work of the hydraulic pressure heat-exchange system of the bypass of the hydraulic pressure with piston type relief valve.
Background technology
It is known that oil temperature in hydraulic system optimum temperature is between 35 ~ 55 degrees Celsius, once temperature increases to over 60 degrees Celsius, the system of hydraulic system will significantly decline, and its equipment fault continuously emerges, cause the stability degradation of equipment it is impossible to ensure that machinery equipment is normally run.Especially season, high oil temperature in full summer, or even machinery equipment can be caused usually to be in stopped status.
The stability of therefore hydraulic pressure heat-exchange system directly influences the working condition of machinery equipment, when in traditional hydraulic pressure heat-exchange system, fluid pressure is excessive, directly result in pressure in heat exchanger excessive radiator is caused damage.General radiator is that have the capacity of a fixed proportion in the collecting tank of radiator, and fluid has necessarily big resistance by radiator heat-dissipation channel interior.Its amount of liquid storage is less, do not buffer, running into the liquid that the temperature difference is big, low temperature environment, flow are uneven, have certain viscosity, under the fluid situations having impulsive force, the pressure of radiator heat-dissipation channel interior also increases therewith, especially in the case of having impulsive force and the larger fluid of ratio of viscosities, because fluid is in the resistance of channel interior, so that fluid can not be run through inside radiator passage, it is allowed to pressure to increase, exceedes the highest operating pressure of radiator, radiator is easy to damage, scraps.
