Embodiment 1

[0035] This embodiment provides a blowout prevention test device for testing the hydration temperature and pressure of the breaking agent, such as figure 1 with figure 2 As shown, it includes an upper flange 1, a nylon cover 2, an asbestos pad 3, a lower flange 4, bolts 5, nuts 6, a round pipe 7, a positioning key 8, a base 9 and a pressure flange 10.

[0036] Further, the round pipe, positioning key and base are all made of No. 20 steel, the base is welded at the lower end of the round pipe, and the positioning key is welded at the symmetrical position of 10 cm from the upper port of the round pipe.

[0037] Further, the asbestos pad can be set in the nylon cover and pressed on the upper port of the round pipe, and the upper and lower flanges, bolts, nuts, asbestos pad, nylon cover and positioning key together realize the function of sealing the nozzle.

[0038] Furthermore, the pressurized flange and the nylon cover drilled in the center are used to pressurize the circular...

Embodiment 2

[0040] This embodiment provides a method for testing the hydration temperature and pressure of the breaking agent. The method is implemented based on the blowout prevention test device for testing the hydration temperature and pressure of the breaking agent described in Example 1. The changing response law realizes the purpose of testing the temperature, and at the same time, the output value of the strain gauge can be converted into the expansion pressure by using the formula (a), including the following steps:

[0041] Step 1: Add water to the test cylinder with the strain gauge attached until it is flush with the mouth of the tube, connect the strain gauge and the PC terminal, turn on the power to debug the equipment and preheat for 20 minutes;

[0042] Step 2: Put the lower flange on the round pipe and pass the positioning key, then rotate it at a certain angle so that it is caught by the positioning key, cover the nylon pad and the pressure flange with the center hole in t...

Abstract

The invention provides an anti-spray test device and a method for testing hydration temperature and pressure of a crushing agent. The anti-spray test device comprises a round pipe, an upper flange ora pressurization flange, a nylon cover, a lower flange and a positioning key. The positioning key is symmetrically disposed on the round tube, the lower flange fits with the positioning key; the nyloncover is disposed on an upper port of the round tube, the upper flange or the pressurization flange is disposed on the nylon cover, the upper flange or the pressurization flange and the nylon cover are tightly connected to the lower flange by bolts and nuts; and centers of the pressurization flange and the nylon cover are provided with drill holes. The anti-spray test device of the invention useswidely available materials, and has simple processing and low cost, neither need for other devices including a press machine and a constant temperature water bath in a test nor hazard to environment.In the invention, the temperature and the pressure data can be simultaneously measured by a set of foil resistance strain gauge, reducing laboratory instruments and simplifying operating procedures.

Description

technical field [0001] The invention relates to a device and method for testing the hydration temperature and pressure of the breaking agent, in particular to a blowout prevention testing device and method for testing the hydration temperature and pressure of the breaking agent, belonging to mechanical experiment technology, rock breaking technology and mining technology. Coal technology and other fields. Background technique [0002] With the acceleration of my country's modernization process, energy consumption has reached an unprecedented height. As the most important energy source, mineral resources meet more than 95% of my country's energy demand. With the depletion of minerals on the shallow ground, my country has shifted the goal of resource mining to deep reservoirs, which has greatly restricted the rock-breaking technology involved in the coal mining process. On the one hand, the initial stress of the reservoir is large and the pressure of the overlying strata is ...
