1. The newly installed piping should be rinsed first.
2. Before using the glass rotor flowmeter, check the technical parameters such as: measuring range, accuracy level, rated working pressure, temperature and other parameters to meet the requirements.
3. Remove the top liner from the flowmeter for transport protection before installation. And check whether the cone is damaged, whether the float can move up and down freely, and it can be installed after normal.
4. Install vertically on a vibration-free pipe. The angle between the centerline of the rotameter and the plumb line should not exceed 5 degrees. Large-diameter flowmeters are heavy, in order to avoid bending of the pipeline, reinforcement measures can be taken when necessary.
5. When installing, avoid the rotor flowmeter being damaged by excessive external force. Open the valve slowly.
6. If necessary, install a filter upstream of the rotameter according to different working conditions in use to prevent impurities from entering the measuring tube, causing the float to become clogged.
7. If the fluid is unstable and has pulsating flow, a buffer can be installed to ensure good measurement of the rotameter to eliminate pulsating flow.
8. When using the glass rotor flowmeter, first slowly unscrew the control valve on the upstream pipe of the flowmeter, and then adjust the flow with the regulating valve to avoid sudden opening and causing the float to rise and damage the cone.
9. Finally, in order to obtain accurate measurement accuracy, it is recommended that the flow rate of the fluid to be measured should be more than 60% of the index flow of the rotor flowmeter.
Ultrasonic Drilling Rig For Geological Survey Investigation
Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and temporary reduction of porosity of the soil. The combination makes penetrating for a large range of soils easy for our Sonic rigs and tooling. The penetration rates in most bedrock are faster with this technology also.
At first glance, a SONIC drilling rig looks very much like a conventional air or mud rotary drill rig. The biggest difference is in the drill head, which is slightly larger than a standard rotary head. The head contains the mechanism necessary for rotary motion, as well as an oscillator, which causes a high frequency force to be superimposed on the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three combined forces allow drilling -to proceed rapidly through most geological formations including most types of rock.
In overburden, the vibratory action causes the surrounding soil particles to fluidize, thereby allowing effortless penetration. In rock, the drill bit causes fractures at the rock face, creating rock dust and small rock particles, which facilitates advancement of the drill bit. In many instances the drilling and coring of rock and earth can be accomplished without the use of any drilling fluid whatsoever. This is an important requirement for environmental drilling projects. Compressed air, drill mud, or plain water can be utilized to remove the cuttings and speed up the operation further, depending on the application that the machine is used for.
The oscillator is driven by a hydraulic motor and uses out of balance weights to generate high sinusoidal forces that are transmitted to the drill bit. An air spring is also incorporated in order to confine the alternating forces to the drill string. The frequency can be varied to suit operation conditions and is generally between 50 and 160 hertz (cycles per second). As a comparison, ordinary household current in many countries alternates at 60 hertz. This frequency range falls within the lower range of sound vibrations that the human ear is capable of hearing.
While the principle behind the SONIC drill rig appears complicated, the machine is actually very simple to operate. The driller only adds vibratory energy to the normal rotary motion. He simply chooses a frequency that gives him the best drilling rate or best core recovery, as the case may be.
