Description

The Magnetic Explosion Proof Pig Signaler Non-Intrusive contains:

Explosion-proof remote transmission display mechanism TZS. (LCD has a heating function, records passing the time, and stores memory 99 times. Remote transmission, explosion-proof mark ExdIICT6Gb, protection grade IP65.) and sensing mechanism YY-FCT. Detachable clamping mechanism and connecting wire. Extension rods (if necessary, generally used for buried pipelines).

When the product is working, there will be a pig with a magnetic force to pass through. At this time, it will display the passing time of the pig and send a switch signal far away for the control of the pigging process to understand the operation of the pig. It stores the number and time of memory passages in the display mechanism at the same time. Memory times: 99 times.

The clamping mechanism (clamp) is selected according to the pipeline specifications, and the staff can fix the clamping mechanism in the required position. Special Note: Pipes with insulation. During installation, the operator attaches the sensing mechanism to the metal pipe wall. Insulate after installation.

The sensing mechanism includes an anisotropic magnetoresistance circuit and a balanced amplifier circuit. There are also low-pass filter circuits, trigger circuits, CPUs, etc. It has a remote switch circuit, display circuit, and reset circuit.

Instructions for Use:

1. Detection function:

①Power-on detection: running/status light – yellow. When power is on, the status light is always on. At the same time, the relay acts once, and the indicator performs self-checking.
②Setting mode: In the setting mode, enter the operation menu. The running light is always on and the signal is not monitored.
③Monitoring status: Slow flashing of the running light indicates that the indicator is working normally and is in monitoring status.
④Action status: signal indicator – blue. When it is detected that there is a signal from the pig with a magnet (or transmitter) passing through, the action signal light will be on. The relay outputs 3S remote signal at the same time.

2. Query function:

Press the select key continuously. Check the query function. Press the enter key. The display will show the number of passes and times the meter has been stored. There is also the time of the last pig pass. So if the number of records exceeds 99, it will update and store the latest 99 records in real time. However, the number of passes displayed on the monitoring interface will continue to increase. By pressing the adjustment key, the maximum cycle can be recorded 990 times. If you want to exit the query function, you can press the enter key continuously. This will leave the query function.

3. Clear function:

The meter automatically records the time of each pass. The instrument can record up to 99 times. If it exceeds 99 times, the instrument will automatically clear the oldest record. To ensure reliable records and efficient inquiries. Therefore, it is necessary to perform a manual reset. The operator presses the select key to select the clear function. Then press the OK button, and the system will clear all internal records.

4. Time adjustment function:

If the display time needs to be adjusted, press the select key to select the time adjustment function. After pressing the enter key, the instrument enters the mode of adjusting time. The hour numbers flash at this time. The user can change the time by adjusting the buttons. Select the year, month, day, hour, minute, and second by selecting keys. Press the adjustment key to adjust the time (only increment, increment to 60 and return to zero). Press the enter key to confirm and exit the time adjustment. At the same time, the meter will store the set time.
No matter what function, more than 3 seconds, if the operator does not press the button. Then the instrument automatically exits all functions. It enters the pig monitoring state.

It is an oil pipeline Pig Signaler

Oil pipeline roller explosion-proof Pig Signaler. It includes an upper indicator meter and an internal Hall sensor. It is attached to the top of the housing and is mounted on the lower part of the indicator. The inside is the upper inner diameter. It is a one-stage stepped cavity structure more minor than the inner diameter of the lower leg. Bottom opening. The connecting sleeve is inserted into the step of the connecting sleeve through the opening at the bottom end of the connecting sleeve. The interior of the above-mentioned connecting sleeve is a through-hole structure. The central axle is installed in the connecting sleeve.

There is a magnet on the top of the center shaft mentioned here. The middle sleeve has a spring. The bottom end is provided with a roller through a fixing pin. Its rollers go deep into the pipe. The connection sleeve outside the central shaft and the pipe are welded and sealed. And our products are also formed by forming the above structure. In this way, the technical problems of high cost and poor use effect existing in the prior art are solved. At the same time, we provide a kind of explosion-proof through ball indicator suitable for small-diameter oil pipeline rollers.

Non Intrusive Pig Signaler

This ball-passing indicator breaks through the magnetic shielding effect of long-distance pipelines in principle. By inducing voltage signals, it also can be amplified to indicate on the spot or forecast at a long distance. Compared with other indicators, this kind of indicator has the characteristics of an accurate signal, simple structure, and easy construction.

When the product is working, the built-in timer runs automatically and displays the standard time. If a pig with a magnetic force passes through. The instrument then displays the time the pig has passed. At the same time, it will transmit a switch signal far away for the pigging process control center to know the operation of the pig. Then the display mechanism simultaneously stores the number of memory passes and the time. Memory times: 50 times.

The sensing mechanism includes an anisotropic magnetoresistance circuit and a balanced amplifier circuit. There are also low-pass filter circuits, trigger circuits, CPUs, and other accessories. There are also supporting remote switch circuits, display circuits,s and reset circuits.

The principle of magnetic particle inspection:

It is to magnetize the workpiece made of magnetically conductive metal material to the saturation level. If the inside of the material is very homogeneous, there are no defects. Then there will be uniformly distributed magnetic field lines inside it. If there are defects such as cracks, slag inclusions, or pores on the surface or near-surface area of ​​the workpiece, these defects will hinder the passage of magnetic lines of force, resulting in magnetic flux leakage. This generates a pair of N, and S pole local magnetic fields on the surfaces on both sides of the defect. At this time, if the surface of the workpiece to be inspected is sprinkled with magnet powder or magnet powder suspension. At this time, the leakage magnetic field will adsorb the magnetic powder. This creates a magnetic particle agglomeration, which clearly shows the image of the defect.

It varies according to the method of magnetic particle inspection. (That is, the timing of spraying magnetic particles and observing and evaluating are different.)

It has two categories:

a. Additive method (continuous method): It sprays magnetic powder while magnetizing the tested workpiece. (magnetic suspension) and observe and evaluate. The advantage of this method is that it can achieve higher detection sensitivity with a lower magnetizing current. It is especially suitable for materials with low coercivity and low remanence (eg mild steel). The disadvantage is that the operation is inconvenient and the inspection efficiency is low.

b. Residual magnetism method: It uses the residual magnetism of the tested workpiece after magnetization for inspection. After the workpiece is magnetized, the magnetizing current can be disconnected, and then the magnetic powder (magnetic suspension) can be sprayed, observed, and evaluated. The advantages of this method are simple operation and high inspection efficiency. The disadvantage is that requiring a larger magnetizing current. (approximately three times the magnetizing current used in the external addition method). It requires the workpiece material to be inspected for high coercivity and remanence. (To ensure that the residual magnetism after magnetization can meet the needs of inspection sensitivity). And the operator must pay attention to controlling the power-off phase when using alternating current or half-wave rectification as the magnetizing current.
