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

[0074] Example 1. When the liquid flows from left to right and the main hydraulic circuit is not smooth, the pressure at the left end of the adjustable pressure relief valve is greater than the pressure at the right end, because the pressure in the fluid channel of the piston on the left side of the diaphragm is greater than that of the piston on the right side of the diaphragm. The pressure in the fluid channel, the fluid pushes the diaphragm to the right, so that the piston also moves to the right. When the fluid hole on the left side of the diaphragm is located in a fluid passage half cavity on the right side, the fluid with higher pressure moves from the left side. The fluid passage of the piston flows out through the fluid hole to a fluid passage half-chamber on the right, and then flows into the fluid passage of the piston on the right, so as to achieve the purpose of pressure relief. At this time, the spring on the left is in a stretched state. The spring on the right is...

Embodiment A

[0078] The accumulator tube is built-in. When the liquid inlet and outlet of the anti-shock accumulator radiator are located at the tops of the first liquid collection tank 501 and the second liquid collection tank 502, the energy storage pipe 500 is installed in the first liquid collection tank 501 and the second liquid collection tank 502. The inside of the second sump 502 is sufficient.

Abstract

The invention relates to a temperature control hydraulic heat exchange device with an adjustable pressure relief valve hydraulic bypass. The device comprises an equipment heating source, a radiator, a tubular heater and a liquid storage box which are in oil path circular series connection; a heat dissipation draught fan is arranged on one side of the radiator, and an adjustable pressure relief valve is in parallel connection with oil paths on the two ends of the radiator; and the device has the beneficial effects of being high in reliability, not prone to being damaged, and capable of ensuring system stable running.

Description

technical field [0001] The invention relates to a temperature-controlled hydraulic heat exchange device with an adjustable pressure relief valve hydraulic bypass. Background technique [0002] As we all know, the optimal temperature of the hydraulic system oil temperature is between 35 and 55 degrees Celsius. Once the temperature rises above 60 degrees Celsius, 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 normal operation of machinery and 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 state of the machine and equipment. When the liquid pressure in the traditional hydraulic heat exchange device is too large, it will directly lead to the excessive pre...
