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

[0070] 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

[0071]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.

Abstract

The invention relates to a working method of a four-way type industrial constant-temperature machine with a spherical pressure-relief valve and a hydraulic bypass. The working method is characterizedby comprising the steps that firstly, an equipment heating source (900) and the industrial constant-temperature machine are connected; and secondly, at the time of starting, an oil storage tank temperature sensor (908) or a hydraulic oil conveying pipeline temperature sensor (103) detects the liquid temperature firstly, when the temperature is lower than 35 DEG C, a heating mode is started, and when the temperature is lower than 60 DEG C, and the refrigerating mode is started. The working method has the advantages of being high in reliability degree, not liable to damage and capable of guaranteeing stable operation of the system.

Description

technical field [0001] The invention relates to a working method of a four-way industrial constant temperature machine with a hydraulic bypass of a ball type pressure relief valve. Background technique [0002] As we all know, the optimal oil temperature of the hydraulic system is between 35 and 55 degrees Celsius. Once the temperature rises above 60 degrees Celsius, the system working efficiency of the hydraulic system will be greatly reduced, and equipment failures will continue to occur, resulting in serious equipment stability. decline, 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. In winter, especially in severe cold areas, the oil temperature is low, the oil temperature inside the hydraulic system is low, the viscosity is high, the fluidity is poor, and the work efficiency is also poor. Forcibly operating in this enviro...
