Henan malpractice Construction Engineering Co., Ltd. is a specialized detection testing company Zhengyang quality monitoring stations to detect, since enterprises in Henan Province is one of detecting the first place through the qualification assessment. Qualified business scope includes pile qualification, qualification grade steel, an indoor environmental qualification, building energy detection, the main testing, materials testing, glass curtain wall detection, detection of roads and bridges, and a number of civil air defense projects detection testing qualification and testing laboratories. Electric hydraulic jack with power instead of manual provided by the electric oil pump is divided into two single-acting and double-acting. Single-acting hydraulic jack is to meet the needs of structure detection synchronized hydraulic loading of specially designed, which is characterized by storage tanks, pumps, valves, etc. are not attached to the jack, so the structure is simple, just by the piston and working cylinder two parts. Quality Inspection larger piston stroke monitoring stations, equipped with top ball joints can be rotated within the range of 15 °. Jack can be mounted upside down according to the structure of testing needs, and appropriate use of multiple jacks synchronous loading system can be adapted to multi-point loading needs. Double-acting hydraulic jack is designed to meet seismic detection applied low cyclic loading (or cyclical loading) specially designed for the needs of its work is characterized by both ends of the cylinder into the hole to the streets have a quality monitoring stations detected Set tubing joints Xinzheng Quality Inspection Supervision Station, alternately through the pump and valve oil, produced by the piston to pull structure, double-acting pressure applied cyclic load. Henan malpractice Construction Engineering Testing Co., Ltd. is a specialized testing company, Henan Province is one of the qualifications in place since the first detection through examination of business. Qualified business scope includes pile qualification, qualification grade steel, an indoor environmental qualification, building energy detection, the main testing, materials testing, glass curtain wall detection, detection of roads and bridges, and a number of civil air defense projects detection testing qualification and testing laboratories. Pseudo-static loading device structure there are many, in the laboratory in the past mainly by mechanical or hydraulic jack jack loading. Such equipment is mainly due to load manually load, degree of automation is not high, the loading process is not easy to control, often resulting in data measurement instability, inaccurate, test result analysis difficult. In recent years, with economic development and science and technology continues to improve, structural loading device with a qualitative change in the structure of the laboratory Many electro-hydraulic servo loading system mainly uses pseudo-static structural loading. Cai quality testing new monitoring stations, the increasing prevalence of testing stations (certified), quality monitoring stations to detect malpractice by Henan Construction Engineering Inspection Limited. Henan malpractice Construction Engineering Inspection Limited (www.hnrsjc.cn) is a leader in Zhengzhou, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. The increasing prevalence of detection leadership with the staff warmly welcome all inquiries negotiations to create a better future for the increasing prevalence of detection.
