Weight on bit gauge Beijing weight on bit gauge Manufacturer of weight on bit gauge price Weight on bit gauge Content introduction:
The weight on bit gauge produced by Beijing Pute Instrument Complete Factory is suitable for drilling rig feed cylinder, piston rod diameter, The parameters of the number of oil cylinders and the maximum unit working pressure value comply with the weight-on-bit table applicable to other types of drilling rigs specified in the table
. This instrument can accurately reflect the weight of the drilling tool and the bottom pressure of the hole during pressurization and decompression drilling during drilling operations, providing a reliable basis for obtaining a reasonable drilling speed. It is suitable for geology, metallurgy, petroleum, chemical industry, coal and other industries. used in various drilling machinery.

Performance characteristics
The instrument is composed of pointer, scale dial, case and buffer. The instrument case is filled with a certain amount of methyl silicone oil, and a buffer is installed in the joint of the instrument to ensure that the instrument's performance in terms of shock resistance and impact resistance can achieve obvious effects.
The elastic element of this instrument is a wave lamp tube (i.e. spring tube), which has high sensitivity and can reflect small pressure changes.
The instrument has reliable performance and simple structure. Suitable for various drilling work needs.

Instructions for use
. Weighing and decompression drilling:
To weigh the drilling tool, lift the drilling tool slightly away from the bottom of the hole and then place the drilling handwheel in the weighing position. At this time, the drilling tool The weight is supported by the hydraulic oil in the lower chamber of the oil cylinder. The instrument pointer rotates clockwise. When the pointer remains stationary, the corresponding value it points to is the weight of the drilling tool.
To help the operator remember, the red arrow in the pressure indicator disk (outer ring moving disk) can be aligned with the weight value. The weighing and decompression indicators are on the same static plate. The same is true for decompression drilling. The difference is that you need to operate the decompression drilling pistol to make the instrument pointer rotate counterclockwise. When the instrument pointer does not move, the pointer is locked. The static disk scale value of the finger is the decompression value when drilling. The actual pressure value of the hole is equal to the weighing value of the arrow lock finger minus the decompression value.
. Pressurized drilling:
First weigh the drilling tool. Assume that the drilling tool weighs Place it in the pressurized position and slowly turn the pressure regulating handwheel of the drilling rig. At this time, the instrument pointer will rotate clockwise. If the pressure at the bottom of the hole is required, the instrument pointer is required to remain on the moving plate. The reading value is the actual pressure value at the bottom of the hole.
5. Precautions
When selecting a weight-on-bit gauge
parameters such as feed cylinder diameter, piston rod diameter, number of cylinders and other parameters of the drilling rig used must be consistent with the data in the above table.
.Hydraulic oil needs to be kept clean frequently. If there is lag in the instrument pointer, unscrew the hexagonal nut of the instrument connector, unscrew the buffer, clean it and install it before use.
.When installing the instrument, fill the pipeline with as much oil as possible and drain out the air.
.If the specifications of the weight-on-bit gauge in the above table cannot meet your needs, please write to us and specify the oil cylinder diameter, piston rod diameter, number of oil cylinders, that is, the maximum pressure value of the unit. Our company can customize it for you at any time.
