Further, consider and tentatively carry out pressure controlled problem, the utility model is provided with preliminary adjusting pressuring knob on air strainer.
The beneficial effects of the utility model are: the utility model solves the withstand voltage explosion bulge test problem of plastic pipe under the effect of 30 ~ 150MPa high-pressure, be conducive to the range of application grasping plastic pipe, prevent from going wrong in pipe applications, for the security of the lives and property of the people provides safeguard, it meets the requirement of national standard to testing equipment completely, and tool has the following advantages:
(1) Output pressure scope is wide, and minimum pressure is from 0MPa, and it is even higher that most high output pressure can reach 150MPa;
(2) control is exported simpler, this high-tension apparatus adopts pressurized air as power source, drive a ram pump, the pressure driving compressed-air actuated Stress control to export by electrical equipment proportional valve control height, the rate of pressure change exported by the flow control controlling pressure-air;
(3) export more steady, in controlling, employ the larger air of compression factor, thus reduce the difficulty of control, make Output pressure more steadily and rate of pressure change stepless time adjustment can be realized to control;
(4) easy to maintenance, adopt split, fractal structure, standalone module is safeguarded simple, and manufactures such apparatus and process condition at present and can meet, but in manufacturing process, corresponding position, parts must meet the demands;
(5) safety non-pollution, due to the drive energy of equipment use and medium be electricity, air, water and equipment itself do not avoid with non-security voltage contacts and threatens the electric shock of operating personnel; The cleaning of the medium such as air, water can not produce environment pollutes, and can produce noise, but can be placed on the region of another relative sound insulation, doing so avoids noise pollution during air compressor work, thus can make that experimental test environment is clean not quietly to be polluted.
