　　With the development of socialist modernization and the deepening of reform and opening up, our country has higher and higher requirements for the use of equipment with more advanced technology, more advanced technology and more accurate precision, and the requirements for installation and maintenance tools in the process of installation and maintenance of these equipment are also higher. more rigorous. Therefore, the demand for tools for the installation and daily maintenance of such equipment is also increasing. Our company designs and produces hydraulic appliances for daily installation, maintenance and maintenance of such equipment. The main products include electric hydraulic pump station series, pneumatic hydraulic pump station series, manual hydraulic pump station series, hydraulic torque wrench series, hydraulic cylinder series, Hydraulic puller series, hydraulic bolt tensioner series, hydraulic nut series, hydraulic sleeper stretcher series, round steel hydraulic shear series, ultra-high pressure hydraulic hose series and peripheral products, etc. Can also provide a complete set of engineering solutions according to customer needs.

　　So what is the importance of WREN's products? Now China is a fast-developing China, and more and more attention is paid to the safety of workers in production work, and the requirements for workers' efficiency in production work are getting higher and higher. Our company's products integrate safety, convenience, speed and precision. While taking into account the safety in the production and construction process, it also greatly improves the efficiency of production work and ensures the precision of equipment installation.

　　The current market demand is for safe, convenient, fast and accurate installation and maintenance tools, especially in some large infrastructures and large electromechanical equipment that use a large number of high-strength bolts, especially heavy machinery and equipment that bears loads and strong shock and vibration. It is particularly important to say that the quality of the bolted connection will directly affect its operational reliability and service life. Many large-scale equipment, such as oxygen tanks in metallurgical enterprises, gas power generation and other departments, are areas where open fire operations are prohibited. Not only to prevent open flames, but also to prevent the generation of sparks and static electricity. Our company's hydraulic products are made of high-tech aerospace materials (aluminum-titanium alloy) and ultra-high-strength alloy steel in the design and production process, which can effectively prevent the generation of sparks, static electricity, and equipment damage or personnel caused by product quality problems. injury occurs. Our tools have safety performance, which greatly improves the safety of workers in production, effectively eliminates the possibility of major safety accidents in production and life in areas where open fire is prohibited, and eliminates major safety hazards.

　　The company's hydraulic products, while taking into account safety, are easy to operate and easy to use, and only one or two workers can be used smoothly. Many metallurgical enterprises are still in the stupid stage when disassembling and assembling large-scale equipment. A dozen or even dozens of workers are used to disassemble one or two large-scale equipment on site, which not only wastes human resources, but also wastes a lot of Inconvenience is caused in the process of annual maintenance or zero-hour emergency repair, and often there is not enough time for emergency repair or insufficient maintenance personnel. With our hydraulic tools, it is relatively easy to complete the above work with only one or two workers. Such as hydraulic torque wrench, in the process of disassembling and assembling bolts, only one person can complete the operation of wrenches under 20 type. The same is true for hydraulic jacks. The operation of hydraulic jacks less than 100 tons can also be completed by only one person to complete equipment lifting and maintenance. The hydraulic puller can also be operated by only one person, and the disassembly of the whole set of equipment can be completed with the cooperation of two masters. This alone frees up a lot of manpower and can be used for other equipment installation or maintenance. And our company's hydraulic products are not only as simple as liberating manpower, but also taking into account the efficiency and speed. The hydraulic electric pump station or hydraulic pneumatic pump station used by our company's hydraulic wrench, hydraulic jack, hydraulic bolt tensioner and other products adopts the world's more advanced three-stage large-flow hydraulic pump station design, and the flow rate reaches 8 liters per minute. As much, the relatively high working pressure can reach 700 kg (700 bar). Greatly improve the disassembly and maintenance speed of large equipment.

　　While ensuring safety, taking into account the convenience and speed, our hydraulic wrench also has high-precision performance. Within the rated output torque range, the user can continuously adjust the output torque by adjusting the pressure of the hydraulic pump station. The company's hydraulic wrench adopts high-precision ratchet operation, and the torque repeatability is as high as plus or minus 3%. And during the operation of the wrench, the constant torque output provides a higher precision value throughout the operation of the wrench. Many large domestic enterprises now use imported equipment, such as TRT power generation (gas waste heat re-power generation) and CDQ power generation in metallurgical enterprises, all of which are imported from abroad. These devices generally use high-strength bolts and have strict requirements for bolt preload. According to the dead wrench used in previous work operations, the pre-tightening of the open-end wrench has completely failed to meet the requirements required by these devices. If it is forcibly installed, the connection quality of the bolts is not good, which will directly affect the operation reliability and service life of the equipment. Using our company's hydraulic products, the constant torque output and the high-precision operation of the ratchet ensure the connection quality of the high-strength bolts in the equipment, which greatly improves the operation reliability and service life of the equipment.

　　To sum up, the tools used in the daily installation and maintenance of large-scale equipment in the current market demand are integrated with safety, convenience, speed, and precision. It is integrated and increases the safety, accuracy and reliability of the equipment after installation or maintenance. The products owned by WREN are suitable for the current market demand.

　　After expounding the tools required by the market and the four characteristics of our company's products in line with the market. Let me briefly describe the application of WREN's products in steel enterprises.

　　Iron and steel enterprises are one of the heavy industries and an important part of the secondary industry. The secondary industry is the backbone of a country, and iron and steel enterprises are the most important part of the backbone.

　　Large iron and steel enterprises have several key metallurgical production departments and maintenance departments. Here, a large domestic iron and steel plant is cited as an example. The steel mill can be divided into sheet mills, electric furnace steelmaking, power companies (other steel mills may be called differently), high-speed wire plants, coking plants, iron-making plants, tropical plants, high-speed lines, small rolling mills (cold, hot), medium-sized rolling mills (cold, hot), converter plants, maintenance and inspection centers. Among them, the maintenance inspection center has a relatively large demand for our company's products. The maintenance and inspection center is a department that conducts maintenance and inspection of the entire steel plant. It is highly professional and has a large demand for tools. Generally, the maintenance and inspection center is responsible for the year-end maintenance of the steel plant or the disassembly and repair of large equipment.

　　Before the specific introduction, let's briefly introduce the performance of our company's hydraulic products. Starting from the hydraulic wrench, the drive type wrench can be equipped from type 1, type 1, type 3, type 5, type 8, type 10, type 20, type 25, type 35. The torque span is between 183N.m-48666N.m. According to the needs of the site, there may be some bolts. The bolts are too long, so that the socket of the drive wrench cannot be inserted, or there are double nuts on the bolt sleeve, or the height of the bolt and the head space is not enough to fit the special work position of the drive wrench. The drive wrench cannot work, and a hollow hydraulic wrench is required at this time. The hollow hydraulic torque wrench has the same working principle as the drive wrench, but its unique feature is that the wrench can be divided into two parts, the working head part and the power head part. The same type of power head remains unchanged. Within the working range of this type, bolts of different sizes can be disassembled and assembled by changing the working head, or by adding a reducing sleeve to change the size of the hexagonal opposite side to achieve disassembly and assembly. The hollow type hydraulic wrench is thinner than the drive type wrench, which can realize the bolt disassembly and assembly in a small space. Hollow wrench models are available from type 2, type 2, type 4, type 8, type 14, and type 30. The torque output is between 232N.m-44593N.m. Standard equipped with 6 meters of double hydraulic hoses (the length of hydraulic hoses for some special stations can be customized). The electric hydraulic pump station can be equipped with KLW4000 as standard. According to the construction situation on site, it is forbidden to work with open flames or in areas with anti-static and sparks. Such as oxygen tanks, gas power generation and other departments. Optional KLW4000 pneumatic hydraulic pump station.

　　Many imported equipment, such as fans, water turbines, air separation towers, air compressors, etc. For bolts with higher precision requirements, the appearance nut may be directly round, not hexagonal. At this time, we will use a hydraulic bolt lifter. According to different bolt specifications, the maintenance center can be equipped with HTA series hydraulic bolt puller, HTB series hydraulic bolt puller, and HTS series hydraulic bolt puller (automatic recovery). HTA series hydraulic bolt lifter is suitable for bolt size M16-M100, tensile force 179-4476KN, and maximum working pressure is 1000-1500Bar. HTB series hydraulic bolt lifter is suitable for bolt size M20-M115, tensile force 338-3793KN, maximum working pressure 1500Bar. HTS series hydraulic bolt lifter is suitable for bolt size M20-M160, tensile force 307-8423KN, maximum working pressure 700-1500Bar. The scope of application of the tensioner can also be customized according to the bolt situation on site. The stretcher can be used with a manual hydraulic pump station or an electric hydraulic pump station. It is true that the manual hydraulic pump station can be used to complete the operation without open flames on site. The length of hydraulic hose is customized according to the construction situation on site.

　　After the equipment bolts are removed, the lifting of large equipment cannot be achieved by manpower, such as fans, electric furnaces, air separation towers, oxygen compressors, etc. At this time, it is necessary to apply a hydraulic jack to lift the equipment before overhauling the inside of the equipment. Jacks are basically divided into two categories: single-acting jacks (spring return or load return) and double-acting jacks. Single-acting jacks can be applied to manual hydraulic pump stations or electric hydraulic pump stations, and manual hydraulic pump stations or pneumatic hydraulic pump stations are prohibited in areas where open fire operations are prohibited. Double-acting jacks are suitable for electric hydraulic pump stations, and pneumatic hydraulic pump stations are suitable for areas where open fire is prohibited. The length of hydraulic hose is customized according to the construction situation on site. The maintenance and inspection center is equipped with hydraulic jacks according to the size of the internal equipment of the steel mill. The minimum can be equipped with SMC series mechanical hydraulic jacks, starting from 5 tons (SMC series hydraulic jacks are suitable for integrated screw hydraulic mechanism, no additional oil pump and oil pipe are required). Our company's single-acting jacks can be divided into RSM series single-acting ultra-thin hydraulic jacks (stroke 6-16MM, capacity 5-150 tons, maximum working pressure 700Bar), RCS series single-acting thin hydraulic jacks (stroke 38-62MM, The capacity is 10-150 tons, the maximum working pressure is 700Bar), RC series single-acting hydraulic jack (stroke 16-362MM, capacity 5-100 tons, maximum working pressure 700Bar), RCH series single-acting hollow hydraulic jack (stroke 8-155MM) , capacity 12-100 tons, maximum working pressure 700Bar, hollow plunger design allows thrust and pulling force), CLS series single-acting heavy-duty hydraulic jack (stroke 50-300MM, capacity 50-1000 tons, maximum working pressure 700Bar), CLL series Mechanical self-locking hydraulic jack (stroke 50-300MM, capacity 50-1000 tons, maximum working pressure 700Bar), CLP series single-acting ultra-thin self-locking hydraulic jack (stroke 40-50MM, capacity 60-520 tons, maximum working pressure 700Bar). Double-acting jacks can be divided into RRH series double-acting hollow hydraulic jacks (stroke 38-258MM, capacity 30-150 tons, maximum working pressure 700Bar, hollow plunger allowable thrust and pull), CLR series double-acting heavy-duty hydraulic jacks (stroke 50-511MM, capacity 10-1000 tons, maximum working pressure 700Bar). Different specifications of jacks can be customized for construction according to on-site work conditions. According to the actual use situation on site, a distributor can be used, one pump station is equipped with multiple jacks, and the lifting workpiece can be moved in parallel. Ensure the precision of equipment installation or maintenance.

　　Hydraulic puller. Our company's vehicle-mounted hydraulic pullers can be divided into LA series fully automatic vehicle-mounted hydraulic pullers (automatic hydraulic lifting, automatic clamping work, automatic drawing) and LA series vehicle-mounted hydraulic pullers. There are also HP series integrated puller tools. Small all-in-one puller tool that can be used to remove annular workpieces such as bearings, gears, and pulleys. The large vehicle-mounted hydraulic puller is a hydraulic tool used for the disassembly of large bearing and hole workpieces. The working principle is to use the claws to pull the bearing or gear, and then use the jack to push outwards to achieve the purpose of disassembling the annular workpiece. The maintenance and inspection center is equipped with a large vehicle-mounted hydraulic puller, which is convenient for the disassembly and maintenance of accessories such as backrest wheels and bearings in large equipment.
