Usage:
JZ series finger weight table is a kind of instrument used to indicate and record the change of suspended weight and drilling pressure of drilling tools during the drilling (workover) operation of petroleum and geological exploration, which can help the driller to master the working parameters in the drilling (workover) operation and judge the working status of drilling tools.
Features:
1.JZ series finger weight gauge has 14 specifications and 23 types for different types of drilling (workover) rigs. The gauge consists of three parts: dead rope fixer, weight indicator and recorder. The dead rope holder can be divided into vertical and horizontal type according to the installation method;
2. The instrument has high precision and reliable performance;
3. Good anti-corrosion performance, anti-corrosion type amplification mechanism adapts to the marine working environment;
4. Dual system type secondary meter is suitable for domestic use as well as meeting the use requirements of foreign users;
5. The pipeline connector adopts quick and self-sealing connector, and each pipeline is connected quickly, conveniently and reliably;
6. The recorder ink records the working curve, which is convenient for establishing the working file of drilling.
Main technical parameters:
1. Accuracy: 2 levels;
2. Dead rope fixer output pressure error: ±1.0%F.S;
3. Sensitivity limit: not more than 0.5% F.S of rated load
4. Instrument working environment temperature: -20℃～55℃ (room temperature type) -40℃～55℃ (low temperature type)
