A multifunctional automatic porosity measuring device

Abstract

The invention relates to a multifunctional fully automatic porosity measuring device, which includes a box cover, a box body, a vacuum pump, a water tank, a water level controller, a mica heater, and a central processor. The box cover is connected to the upper end of the box body, so The front of the box is provided with a display screen and operating buttons. The display screen and operating buttons are respectively connected to the central controller. A vacuum pump is connected to the hollow part inside the box. Mica heaters are provided around the box. The hollow part of the body is connected to the water tank through the water inlet pipe and the water discharge pipe respectively. The central processor controls the water inlet and discharge of the water inlet pipe and the water discharge pipe, and controls the startup and shutdown of the vacuum pump and mica heater. The water level controller is located in the hollow of the box. part, the water level controller is connected to the central processor. This device improves the measurement accuracy of specimen porosity, shortens the measurement cycle, improves measurement efficiency, reduces the investment of manpower and resources, and ensures the continuity of subsequent work. It is also simple to operate and meets the requirements of the green concept.

Description

technical field [0001] The invention relates to a multifunctional automatic porosity measuring device, which belongs to the technical field of civil engineering measuring equipment. Background technique [0002] With the rapid rise of civil construction and the in-depth development of experimental research, the properties of materials have become the basic content of the research work of various scholars. As a basic physical index of materials, porosity reflects the compactness and internal properties of materials, which in turn is related to engineering reliability and safety. However, the existing porosity measurement method is cumbersome to operate. Generally, it needs to be vacuum-dried first to measure its dry mass, and then vacuum pumped to saturate the test piece to measure the saturated mass of the test piece. It can be calculated from the mass difference before and after. The pore volume of the test piece is finally calculated for the porosity of the test piece. T...
