Temperature Controlled Industrial Chillers with Hydraulic Bypass with Ball Pressure Relief Valve

Abstract

The invention relates to a temperature-controlled industrial refrigerator with a hydraulic bypass of a ball-type pressure relief valve, which includes a hydraulic oil delivery pipeline, and the hydraulic oil delivery pipeline is from the hydraulic oil inlet to the hydraulic oil outlet. A hydraulic oil delivery pipeline delivery pump, a radiator, a tubular heater and a heat exchange device are arranged in sequence between the outlets, and a heat dissipation fan is arranged on one side of the radiator, and the cooling outlet of the heat exchange device to the cooling inlet The cooling pipeline is provided with a gas-liquid separator, a compressor, a condenser, a liquid receiver, a dry filter, a cooling pipeline solenoid valve and a throttling device in sequence, and the cooling pipeline and the throttling device between the compressor and the condenser A cooling pipeline bypass valve is arranged between the cooling pipelines leading to the heat exchange device; a ball type pressure relief valve is arranged in parallel on the oil circuits at both ends of the radiator. The invention has the advantages of high reliability, not easily damaged, and stable operation of the system.

Description

technical field [0001] The invention relates to a temperature-controlled industrial refrigerator 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 industrial refrigerator directly affects the working state of the equipment. When the liquid pressure in the traditional industrial refrigerator is too high, it will directly lead to the excessive pressure in the heat exchanger and ...

AI Technical Summary

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
