sealing hole implement
sealing hole implement
Use:
JN- type capsule sealing hole implement is used for enveloping drilling hole quickly in order to measure the initial velocity of the gas emitting from the hole, forecast the risk of coal and gas emitting. This sealing hole implement can also be used to seal the drilling hole and measure the natural discharging amount of gas from the drilling hole.
Structure:
It is composed of capsule, gas discharging pipe, gas filling tube and air pump. Each section of the gas discharging pipe is 1m long, altogether 10 sections. The seal depth could be adjusted freely within 10m.
Technical Parameter:
Capsule Air Filling Pressure: 0.150.2Mpa
Hole Diameter: 4250mm
Maximum Sealing Hole Depth: 10m
Air Filling Diameter: 6mm
Application Method and Note: 1. Pull out the drill rod immediately when the hole reaches initial velocity measurable length of gas emitting, put the sealing hole to certain depth, make the gas discharging amount room length 0.5m (when forecasting the risk through gas emitting initial velocity from the hole) and 1m (when forecasting the risk through drilling crumbs amount and maximum gas emitting initial velocity), turn on the valve, inflates air by the air pump to the capsule until sealing hole implement is unable to pull out by hands, then close the valve.
JNType Capsule Sealing Hole Implement
1. Measure the initial velocity of the gas emitting by flow rate. When finishing the measurement, turn on the valve, make the capsule to deflate, and extract the sealing hole implement.
2. This hole can be reused; the sealing holes key components can be replaced very conveniently.
Specification: Standard or according to customers requirements
Packing: carton or according to customers request
Note: we can arrange production under American Standard (ANSI), German Standard (DIN), Japanese Sta
