Cooling device of testing machine

Abstract

The invention discloses a cooling device of a testing machine. The cooling device comprises a first water storage tank which is a container with an opening in the upper and a second water storage tank which is a container with an opening in the upper, the second water storage tank and the first storage tank are arranged in a gradient manner, the first water storage tank is higher than the second water storage tank in position, the top of the second water storage tank is communicated with the lower portion of the water level of the upper portion of the first water storage tank through a second water feeding pipe, the bottom of the second water storage tank is communicated with the bottom of the first water storage tank through a second water draining pipe, the bottom and the top of the second water storage tank are communicated through a third circulating water pipe, and a flow control valve is arranged on the third circulating water pipe; a temperature control device and a water pump are arranged on the first circulating water inlet pipe, and the temperature control device detects the temperature of cooling water of the first circulating water inlet pipe, and controls the opening degree of the flow control valve according to the set temperature value so as to achieve cooling. According to the device, three-time cooling and automatic temperature adjusting functions of water can be achieved, the cooling effect is good, used water resources are few, and the device is environment-friendly and low in energy consumption.

Problems solved by technology

[0002] At present, many universities, scientific research institutions and enterprises often involve universal testing machines, fatigue testing machines, bending and torsion testing machines, etc. in the process of material performance testing and testing. The testing machines themselves are very expensive and the maintenance costs are relatively high. At the same time, the precision requirements of the testing machine are also high, and the equipment will inevitably generate more heat during operation, and for most materials, the temperature will be too high to cause thermal expansion, and for the testing machine, it will affect its test accuracy, etc. , which often requires cooling treatment to ensure the constant oil pressure of the testing machine and the stability of the performance of the equipment. It is also necessary to prevent the premature aging of the lubrication and hydraulic oil caused by excessive temperature, thereby reducing the service life of the lubricating oil and hydraulic oil.

However, if the cooling gradient is too large or too small during the cooling process, it is not conducive to the safe and stable operation of the equipment.

If the cooling gradient is too small, the actual cooling effect will not be achieved. If the temperature is too high, the oil pressure in the equipment will be unstable, which will affect the stability of equipment operation and the accuracy of the test; otherwise, the cooling gradient will be too large, and long-term operation will also cause energy loss. and waste of water resources

At present, all units generally use tap water to directly cool down, which increases the error of the test and also reduces the service life of equipment and oil, and also wastes a lot of water resources, which is very unfavorable to the energy-saving concept of enterprises.

[0003] In terms of equipment installation space, many units use independent tap water single circulation to directly cool down, which is acceptable for short-term operation of a single equipment, but there is obviously a huge waste of resources (installation space, tap water and circulation equipment materials) for multiple equipment , especially for multiple devices running at the same time, the waste is particularly obvious
