Working method of temperature control hydraulic heat exchange system with ball pressure release valve and for hydraulic bypass

Abstract

The invention relates to a working method of a temperature control hydraulic heat exchange system with a ball pressure release valve and for a hydraulic bypass. In the initial operation stage of an equipment heating source, the liquid temperature is lower than 35 DEG C, a radiating fan is not turned on, a tubular heater is started, the oil temperature is increased to within the range of 35-55 DEG C, then the tubular heater is turned off, and after the equipment heating source is operated for some time, the radiating fan is turned on when a temperature sensor detects that the temperature is higher than 60 DEG C; and when a radiator is blocked or the internal pressure of the radiator is too high, the pressure on one side of the ball pressure release valve is higher than the pressure on the other side of the ball pressure release valve, due to the fact that the pressure in a fluid flow channel on the high-pressure side of a ball is higher than the pressure in the fluid flow channel on the low-pressure side of the ball, fluid pushes the ball to move upwards and moves in the fluid flow channel from the high-pressure side to the low-pressure side, the purpose of pressure release is achieved, and a main hydraulic path is unobstructed again until the pressures on the two sides of the ball are equal. The working method has the advantages that the reliability is high, damage is not prone to occurring, and the stable operation of the system is ensured.

Description

technical field [0001] The invention relates to a working method of a temperature-controlled hydraulic heat exchange system 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. There is no guarantee that the machine will function properly. 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 system directly affects the working status of the machinery and equipment. When the liquid pressure in the traditional hydraulic heat exchange system is too high, it will directly lead to ...

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
