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

[0067] 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

[0068] 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.

[0069] 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 A

[0071] 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 working method of a spherical pressure release valve-equipped temperature control hydraulic heat exchange device of a hydraulic bypass. The working method is characterized in that during the early operation stage of a device heating source, the liquid temperature is 35 DEG C or below, a heat radiating fan is not started, a tubular heater is started, the oil temperature is increased to 35 to 55 DEG C, then, the tubular heater is turned off, when the device heating source operates for certain time, a temperature sensor detects that the temperature is 60 DEG C or above, and the heat radiating fan is started; and when a radiator is blocked or the internal pressure of the radiator is too high, the pressure on one sides of spherical pressure release valves is higher than the pressure on the other sides of the spherical pressure release valves, the pressure in a fluid channel of the high pressure sides of balls is higher than the pressure in the fluid channel of the low pressure sides of the balls, a fluid pushes the balls to move upwards, and the fluid moves from the high pressure sides to the low pressure sides in the fluid channel to achieve a pressure relief purpose till the pressure on the two sides of the balls is equal and a hydraulic main path is smooth. The working method has the advantages that the reliability is high, the radiator is not liable to damage, and stable operation of the system is guaranteed.

Description

technical field [0001] The invention relates to a working method of a temperature-control 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...
