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

[0102] 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 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 move to the right, so that the piston also moves to the right. The piston fluid channel flows out through the fluid hole to a fluid channel half cavity on the right, and then flows into the right piston fluid channel, 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 in a compressed state until the pressure on the left and right sides of the diaphragm is equal, the piston returns to its original position, and the main hydraulic circuit returns unobstruc...

Embodiment 2

[0103] Example 2. When the liquid flows from left to right and the main hydraulic circuit is blocked, the pressure at the right end of the adjustable pressure relief valve is greater than the pressure at the left end, because the pressure in the fluid channel of the piston on the right side of the partition is greater than that of the piston on the left side of the partition The pressure in the fluid channel, the fluid pushes the diaphragm to move to the left, so that the piston also moves to the left. The piston fluid channel flows out through the fluid hole to a fluid channel half cavity on the left, and then flows into the left piston fluid channel, so as to achieve the purpose of pressure relief. At this time, the spring on the right is in a stretched state. The spring on the left side is in a compressed state until the pressure on the left side and the right side of the diaphragm are equal, and the main hydraulic circuit returns unobstructed.

Embodiment A

[0106] The accumulator tube is built in. When the liquid inlet and outlet of the anti-impact energy storage radiator are located on the top of the first liquid collection tank 501 and the second liquid collection tank 502, the energy storage tube 500 is installed in the first liquid collection tank 501 and the second liquid collection tank 502. The inside of the second liquid collection tank 502 is enough.

Abstract

The invention relates to an industrial temperature control thermostat with adjustable pressure relief valve hydraulic bypasses. The industrial temperature control thermostat is characterized by comprising a hydraulic oil delivery pipeline, wherein a hydraulic oil delivery pipeline delivery pump, radiators, a heat exchange device and a tubular heater are sequentially arranged on the hydraulic oil delivery pipeline from a hydraulic oil inlet to a hydraulic oil outlet; a heat exchange pipeline is connected between an upper heat exchange connector and a lower heat exchange connector of the heat exchange device; a gas-liquid separator, a compressor, condensers, a heat exchange pipeline bypass valve, a four-way valve, a first one-way valve, a first reservoir, a first drying filter, a first heatexchange pipeline electromagnetic valve, a first throttling device, a second one-way valve, a second reservoir, a second drying filer, a second heat exchange pipeline electromagnetic valve and a second throttling device are arranged on the heat exchange pipeline; and adjustable pressure relief valves are arranged on oil circuits at the two ends of the radiators in parallel. The industrial temperature control thermostat has the beneficial effects of being high in reliability degree and not prone to damage and guaranteeing stable operation of a system.

Description

technical field [0001] The invention relates to a temperature control industrial constant temperature device with an adjustable pressure relief valve hydraulic bypass. 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 ca...
