Portable maintenance device

Abstract

The invention discloses a portable maintenance device which comprises a control and display system, a maintenance room, a heating system and a humidifying system, wherein the humidifying system comprises a spray humidifying device and a humidity sensor; the spray humidifying device comprises at least a sprayer which is arranged in the maintenance room; the humidity sensor is arranged in the maintenance room and connected with the control and display system; and the heater and the spray humidifying device are respectively controlled by the control and display system. The portable maintenance device disclosed by the invention has the advantages of simple structure, small volume, convenience in movement, low cost and high temperature and humidity control accuracy; and the heating, humidifying and sealing systems of the device are scientifically designed and is practical, the temperature and humidity stability in the maintenance are good, thus the problems of the traditional maintenance box, such as poor temperature and humidity control accuracy, great temperature fluctuation and difficulty in movement, are solved.

Description

technical field [0001] The invention relates to a test device, in particular to a portable maintenance device. Background technique [0002] In many test occasions, it is necessary to control the temperature and humidity of the sample curing environment more precisely, and it is required that the temperature and humidity gradients in the entire curing environment be as small as possible. For example, the mortar length method is used to test the concrete aggregate alkali silicic acid ( When the ASR) is active, after the sample is prepared, it needs to be maintained at 38°C ± 2°C and relative humidity above 95%. Currently, there are two methods for specimen maintenance: [0003] 1. Put the specimen directly into the curing box for curing. The temperature and humidity inside the curing box must meet the conditions of 38°C±2°C and relative humidity above 95%. [0004] 2. Put the specimens into the curing cylinder, line the cylinder with absorbent paper to make the air in the ...

AI Technical Summary

Problems solved by technology

The cost of this device is very high, and it is not realistic to realize it.

At the same time, the temperature in the box fluctuates greatly, and the heating system and refrigeration system start frequently, which not only causes excessive energy consumption, but also greatly shortens the service life of the control system.

At the same time, it is difficult for the sensor to achieve accurate data feedback under such working conditions. As a result, the maintenance temperature and humidity cannot be guaranteed, which further aggravates the temperature fluctuation
