Industrial constant temperature device of hydraulic bypass with adjustable type pressure relief valve

Abstract

The invention relates to an industrial constant temperature device of a hydraulic bypass with an adjustable type pressure relief valve. The industrial constant temperature device of the hydraulic bypass with the adjustable type pressure relief valve is characterized by comprising a hydraulic oil conveying pipeline which is sequentially provided with a hydraulic oil conveying pipeline conveying pump, a cooler and a heat exchanging device between a hydraulic oil inlet and a hydraulic oil outlet; a heat exchanging pipeline is connected between an upper heat exchanging connection port and a lowerheat exchanging connection port of the heat exchanging device, and is provided with a gas-liquid separator, a compressor, a condenser, a heat exchanging pipeline bypass valve, a four-way valve, a first one-way valve, a first liquid storing device, a first drying filter, a first heat exchanging pipeline electromagnetic valve, a first throttling device, a second one-way valve, a second liquid storing device, a second drying filter, a second heat exchanging pipeline electromagnetic valve and a second throttling device; and the adjustable type pressure relief valve is arranged on an oil way at thetwo ends of the cooler in parallel. The industrial constant temperature device of the hydraulic bypass with the adjustable type pressure relief valve has the beneficial effects of being high in reliability degree, not prone to damage and capable of guaranteeing stable running of the system.

Description

technical field [0001] The invention relates to an industrial constant temperature device of a hydraulic bypass with an adjustable 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 environment will cause hydraulic ...

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
