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

[0066] 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

[0067]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.

Abstract

The invention relates to a four-way type industrial thermostat for hydraulic bypass with adjustable pressure relief valves. The industrial thermostat is characterized by comprising a hydraulic oil delivery pipeline, a hydraulic oil delivery pipeline transfer pump, a radiator and a heat exchange device are successively arranged between a hydraulic oil inlet and a hydraulic oil outlet on the hydraulic oil delivery pipeline, a heat exchange pipeline is connected between an upper heat exchange connection port and a lower heat exchange connection port of the heat exchange device, and a gas-liquid separator, a compressor, a condenser, a heat exchange pipeline bypass valve, a four-way valve, a first check valve, a first liquid storage device, a first dry filter, a first heat exchange pipeline solenoid valve, a first throttle device, a second check valve, a second liquid storage device, a second dry filter, a second heat exchange pipeline solenoid valve and a second throttle device are arranged on the heat exchange pipeline; the adjustable pressure relief valves are arranged in parallel on an oil passage at both ends of the radiator. The industrial thermostat has the advantage of high reliability and is not easy to damage, and stable operation of a system is ensured.

Description

technical field [0001] The invention relates to a hydraulic bypass four-way industrial constant temperature machine 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 hydrau...
