Problems solved by technology

It has a small liquid storage capacity and no buffer. In the case of large temperature difference, low temperature environment, unbalanced flow, liquid with a certain viscosity, and fluid with impact force, the pressure inside the heat dissipation channel of the radiator will also increase. , especially in the case of impact force and relatively high viscosity fluid, due to the resistance of the fluid inside the channel, the fluid cannot quickly pass through the inside of the radiator channel, so that the pressure increases, exceeding the maximum operating pressure of the radiator, and the radiator is very Easily damaged and scrapped

Embodiment 1

[0054]Example 1. When the liquid flows from left to right and the main hydraulic circuit is blocked, the pressure at the left end of the ball pressure relief valve is greater than the pressure at the right end, because the pressure in the fluid channel on the left side of the ball is greater than the pressure in the fluid channel on the right side of the ball Pressure, the fluid pushes the ball upwards, the bottom of the ball forms a space for the fluid to move, the fluid moves from left to right in the fluid channel, so as to achieve the purpose of pressure relief, until the pressure on the left and right sides of the ball is equal, the ball returns to its original position position, the main hydraulic circuit returns unobstructed.

Embodiment 2

[0055] Example 2. When the liquid flows from left to right and the hydraulic main road is blocked, the pressure at the right end of the ball relief valve is greater than the pressure at the left end, because the pressure in the fluid channel on the right side of the ball is greater than the pressure in the fluid channel on the left side of the ball Pressure, the fluid pushes the ball upwards, the bottom of the ball forms a space for the fluid to move, the fluid moves from right to left in the fluid channel, so as to achieve the purpose of pressure relief, until the pressure on the left and right sides of the ball is equal, the ball returns to its original position position, the main hydraulic circuit returns unobstructed.

[0056] The radiator 5 is an anti-impact energy storage radiator, the radiator 5 includes a radiator body and an energy storage tube 500, and the radiator body includes a first liquid collection tank 501 and a second liquid collection tank arranged vertically...

Embodiment 1

[0058] The accumulator tube is built in. When the liquid inlet and outlet of the anti-impact energy storage radiator are located on the top of the first liquid collection tank 501 and the second liquid collection tank 502, the energy storage tube 500 is installed in the first liquid collection tank 501 and the second liquid collection tank 502. The inside of the second liquid collection tank 502 is enough.

Abstract

The invention relates to a hydraulic heat exchange device of a hydraulic bypass with a spherical pressure release valve. The hydraulic heat exchange device comprises an equipment heating source, a heat radiator and a liquid storage box which are in oil path circulation series connection. A heat radiation draught fan is arranged on one side of the heat radiator. The spherical pressure release valve is arranged on oil paths at the two ends of the heat radiator in parallel. The hydraulic heat exchange device has the beneficial effects of being high in degree of reliability and not prone to being damaged and guaranteeing stable system operation.

Description

technical field [0001] The invention relates to a hydraulic heat exchange device with a hydraulic bypass of a ball type pressure relief valve. Background technique [0002] As we all know, the best oil temperature of the hydraulic system is between 35 and 55 degrees Celsius. Once the temperature rises above 60 degrees Celsius, the system of the hydraulic system will drop significantly, and equipment failures will continue to occur, resulting in a serious decline in the stability of the equipment. The proper functioning of the machine equipment cannot be guaranteed. Especially in the midsummer season, the oil temperature is too high, and even the machinery and equipment are often shut down. [0003] Therefore, the stability of the hydraulic heat exchange device directly affects the working status of the machinery and equipment. When the liquid pressure in the traditional hydraulic heat exchange device is too high, it will directly lead to excessive pressure in the heat excha...
