Yunnan Electric Power Design Institute ordered Hongzhan LP-225U high and low temperature alternating heat and humidity test chamber
Founded in 1958, Yunnan Electric Power Design Institute is a professional design institute engaged in power engineering survey and design. It holds a comprehensive Class A certificate issued by the Ministry of Construction, a Grade A certificate for power engineering design, a Class A certificate for power engineering consulting, and electric power. Grade A certificate for engineering general contracting and Grade B certificate for environmental impact assessment.
It can undertake the design of large, medium and small power generation projects for various energy sources in the power industry, and the design of power transmission and transformation projects with voltage levels of 500kV and below. Since the establishment of the institute, Yunnan Electric Power Design Institute has completed 40~50 power generation engineering designs; completed 562 substation engineering design, of which 500 kV substation engineering design capacity is 7500 MVA; completed 728 transmission line engineering design Among them, the 500 kV line is designed to be 2000 km. About 103 of the designed projects have won national, provincial and ministerial awards for excellent survey and design and scientific and technological achievements.
In 1994, Yunnan Institute was rated as the seventh comprehensive strength of Yunnan Province survey and design unit; in 1996, it became one of the “Top 100 National Survey and Design Comprehensive Strength Unitsâ€; in 1997, it passed the ISO9001 Quality Management System Certification of China Great Wall (Tianjin) Quality Certification Center; In 1999, he was promoted to the national level scientific and technological undertaking archives management unit; in 2002, the national engineering project management ranked the 29th, and the engineering general contracting 100 ranked the 89th, all entered the top 100; in 1996, he was awarded the title of Yunnan Civilized Unit and Maintained to this day; in 2003, won the title of the double civilized unit of Yunnan Power Group Corporation, and was awarded the title of Civilized Unit of China Southern Power Grid Corporation in 2004.
In the “West-to-East Power Transmission†and “Cloud Power Delivery†strategy implementation projects, Yunnan Institute will continue to carry forward the enterprise spirit of “unity, truth-seeking, innovation and dedicationâ€, abide by “focus on customer needs, everyone fulfills their duties and provides satisfactionâ€. The quality policy of “service†strives to become a domestic first-class electric power design enterprise in Southeast Asia.
The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
