1. Safety measures for the pumping system and the pumping station 1. Throwing system safety measures 1. Measures to prevent and control gas hazards during pumping and drilling Drill field before drainage (hole) construction, construction work practices must be prepared to develop construction safety measures during drilling, the gas must be equipped with a full-time inspectors, strict implementation of the relevant provisions of the "Coal Mine Safety Regulations", such as anhydrous put an end to drilling, Gas violations and other violations. In the event of drilling holes during drilling, it is necessary to stop drilling immediately, take measures and report to the relevant leaders. 2. Pipeline anti-leakage, anti-smashing, anti-charge, anti-drum measures The suction system must be equipped with a negative pressure measuring device and a shut-off valve. The newly laid pipeline should be inspected for air tightness, and the normal pumping pipeline should be regularly checked for air tightness. Although the roadway for laying the pipeline is not the main transportation lane, the warning sign should be hung on the pipeline. The exterior of the pipeline is painted red to show the difference, reminding the vehicle to pay attention, and it is necessary to patrol every day and find the problem to be replaced in time. The pipeline shall be spanned and hung at the fork of the roadway, and the hanging height shall not be less than 1.8m. When the pipeline is laid on the floor of the roadway, in order to prevent the bottom drum from damaging the pipeline, the pipeline shall be padded with a pier and the height of the cushion shall not be less than 0.3m. The underground pipeline should be avoided as much as possible with the communication and power cables to prevent the pipeline from being charged. 3. Anti-skid measures for inclined lanes and vertical lanes When the pipeline is arranged in the inclined lane and the vertical lane, it is fixed on the support in the roadway with a semi-circular iron clip, and the support is placed under the bottom. 4. Anti-corrosion measures for pipeline anti-corrosion and ground pipelines The piping of the pumping system must be painted with red or black anti-rust paint to prevent corrosion. Whether the ground pipeline is overhead or buried in the trench, an insulation layer should be placed on the outside of the pipeline to prevent the pipeline from freezing and cracking in winter. 2. Safety measures for pumping and pumping stations 1. Anti-tempering and anti-explosion measures before and after pumping gas pump In order to ensure the safe drainage of gas, an explosion-proof and anti-tempering device is arranged at the appropriate position of the suction pipe and the outlet pipe of the pump. 2. Throwing pump room lightning protection and fire prevention measures A single-needle lightning protection device is installed in the venting pipe near the pumping station and the pumping room. The height of the lightning protection device should exceed 5m of the pumping room and the venting pipe, and the lightning conductor should be buried below the surface of the ground for 3m. Page 2 / (2 pages) Fire-fighting equipment such as dry powder fire extinguishers and sand boxes must be installed in the pump room. 3. The concentration of gas drainage requirements and explosion protection measures under the prescribed concentration When the concentration of gas is less than 30%, the number of concentration inspections should be increased, not less than once every 15 minutes. At the same time, report to the mine manager and chief engineer and find out the cause and take measures in time; when the gas concentration of the pumping drops to 25% At the same time, the gas pump must be stopped immediately, and the gas is diverted to the venting pipe and naturally emptied by gas pressure and buoyancy. The gas concentration in the pump room shall not exceed 0.5%, and the concentration of 0.3m gas near the body shall not exceed 1%. Otherwise, the pump must be stopped to find out the cause and deal with it. 4. Safety management measures (1) Non-explosion-proof electrical appliances shall not be used in the pump room to prevent open flames; (2) Establish a maintenance system for pumping equipment. Regularly inspect and repair the pumping equipment, find problems in a timely manner, and report the relevant situation to the competent department and the leader in a timely manner; (3) Establish a system for stopping and transporting the pumping equipment. Without the research of relevant departments and leaders, no one shall stop the pumping equipment without permission, and shall not adjust the pumping negative pressure of the pumping system without permission; (4) Establish a regular inspection system for pumping parameters. Every measurement point of the pumping system must be comprehensively observed every three days. If conditions are met, it should be measured once a day. Each observation must be filled in the daily discharge report; gas concentration, positive pressure, negative pressure and flow in the gas pump room. The water temperature must be measured and recorded every 10 to 30 minutes, and a record account should be established; (5) Establish a shifting system for the duty station of the pumping station; (6) The pump room duty room is set up with a direct communication mine dispatching room. Second detection and monitoring system 1. Determination of detection and monitoring parameters and equipment location The detection and monitoring parameters of the underground pipe network are: pumping negative pressure, gas concentration, gas flow; measuring location: dry pipe, branch pipe, pumping and drilling. Ground drainage pipeline detection and monitoring parameters: intake pipe negative pressure, gas concentration, gas flow, etc., exhaust pipe positive pressure and pumping pump shaft temperature, circulating cooling water temperature, pump room indoor gas concentration. Measurement location: pump house intake pipe, exhaust pipe and pump room. 2, inspection and control system automation and equipment selection The underground pipeline inspection and monitoring system adopts manual method. The detection equipment includes standard orifice flowmeter (FKL series), CJG gas concentration detector and U-type water column gauge. The control of pipeline system mainly depends on the shut-off valve. The monitoring and monitoring of the pump house and ground pipelines are monitored and monitored automatically by the monitoring system. 3. Equipment for testing instruments and instruments Pumping monitoring instruments: KJ90NB type monitoring system for pumping station, CJG-3, CJG-1 type test gas concentration is two each, 1.5mU Hg type of water meter and meter 2 each. Downhole drainage system detection instrumentation: two sets of CJG-3, CJG-1 gas concentration tester, FW-2 high negative pressure gas take-up device, 0.8mU type water column meter, FKL series orifice flowmeter, There are 2 Φ325mm orifice plates, 6 Φ159mm orifice plates, 4 Φ219mm orifice plates and 10 Φ75mm orifice plates for flow detection.
The Anomatic series of high-quality deep drawn Aluminum Canisters is designed to be compatible with your chosen valves, Actuators and drug formulations. Our deep drawing process ensures a consistent side wall thickness using high strength aluminum which is far superior to other forming methods. The aluminum is work hardened during the deep draw process and the surface mechanically polished providing a smooth, hard internal finish suitable for use with both CFC and HFA propellants.
Our standard canister sizes are 10ml, 14ml and 19ml, with customized sizes available. Our canisters are also available in anodized and plasma coated finishes.
Why Anomatic
Headquartered in New Albany, Ohio (USA), Anomatic is the world`s leading supplier of anodized aluminum solutions and offers:
· U.S. and Asia based manufacturing
· State-of-the-art facilities
· Unmatched capacity at 2.5 billion units annually
· cGMP compliant and ISO14001 and ISO9001 certified
· Advanced surface treatment options
· Unrivaled lead times
Aluminum anodization is an electrochemical process that enhances the strength, durability, and appearance of aluminum. When aluminum is oxidized, super-strong oxide (anodic) layers [grow" on the surface of the metal. These new layers are highly resistant to wear and corrosion.
The exacting part to part consistency achieved with our unique anodizing system cannot be obtained with conventional hoist line systems. Conventional anodizing systems present parts with varied coating thicknesses and voids formed due to air pocketing.
A consistent uniform 6 µm anodic film thicknesses will protect certain drug formulations and the canister from degradation. Heavier film thicknesses of up to 12µm can be provided to meet your more demanding application.
