The quality of the overall heat treatment of domestic large-scale pressure vessels is excellent

Drying equipment

Northeast Jilin Engineering & Testing Company Jilin Yaxin Testing Branch Company completed the overall heat treatment construction task of the second crystallizer of PTA Phase II project of Xianglu Petrochemical (Zhangzhou) Co., Ltd. in Sinopec Ningbo Tianyi Petrochemical Heavy Equipment Manufacturing Co., Ltd., creating a large domestic pressure The heat treatment of the container as a whole has the shortest construction time, the thickest wall thickness, the highest quality, and the highest quality of construction. It has been verified by authoritative experts that the overall heat treatment quality is excellent.

The overall heat treatment task of the pressure vessel undertaken by Jilin Yaxin Testing Branch is the biggest difficulty in the construction of the project. The crystallizer has a diameter of 10 meters, a height of 24.26 meters, a wall thickness of 150 mm and a net weight of 890 tons. It is currently the largest pressure vessel in China. Due to the product's wall thickness and weight, the equipment is particularly high and cannot be heat-treated in the furnace, and only the internal heat treatment of horizontal whole heat treatment can be performed.

Jilin Yaxin Inspection Branch has carefully designed and fully demonstrated key technologies such as combustion technology and diversion technology, formed a complete technical method, and passed a technical demonstration by a multi-faceted expert group of domestic experts, Japanese experts, and owners. .

The first Safety precautions for LZ600 wire drawing machine

1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.

1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.

1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.

1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.

1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.

1. 6 Before starting the machine, check whether the safety device is normal.

1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.

1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.

1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.

The second Delivery inspection

2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.

2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.

2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use
