Pig Indicator Mechanical

Description

A pig indicator is a mechanical device used in oil pipelines. Pig indicator for pigging oil, gas, water, etc. However, it is not only easy to install but also can meet the requirements of various pipe indicators. The pig indicator needs regular maintenance during use, including cleaning the surface of the device, changing the battery, checking the sensor and line connection, etc. On the other hand, if the device is faulty or abnormal, contact professional technicians for repair and maintenance.

Therefore, removing the tubing pig indicator. The line valve must be closed to ensure that there is no pressure in the line. Then disassemble the equipment according to the steps in the equipment manual. Pay attention to protecting the surface and internal parts of the equipment to avoid damage.

The ball type indicator of an oil pipeline has the following advantages: first, it has the characteristics of waterproof, dustproof, and earthquake resistance, which is suitable for use in all kinds of harsh environments; Second, easy to use, highly reliable, can improve the operation efficiency and safety of the pipeline. Third, easy to disassemble. Demolition tools can be used in conjunction with it. In a word, the oil pipeline ball indicator is a very practical device, which can ensure the normal operation and safety of the pipeline.

Mechanical Pig Indicator

The mechanical through ball indicator is based on the mechanical through ball indicator, in the display part
It adopts the explosion-proof design of an aluminum alloy shell, which is mainly suitable for explosive places (natural gas, refined oil, etc.). So it is intuitive and easy to use. The display part adopts an embedded single-chip microcomputer, digital tube display, and intelligent control, and provides normal time display and ball-passing time display.
Transmitting a conduction switch signal remotely through an instant. It is the necessary equipment in the pipeline pigging and descaling process in explosion-proof places. And It combines the advantages of various passing indicators and adds its own characteristic functions. Its advantages: first, it has an intuitive indication. Second, stable performance, third, easy to use. Users provide more satisfactory service.

Mechanical Pig Indicator Features:

(1) This product is the basic type with the least components, which can independently complete the basic function of the ball indication. (2) When the product works, first of all, a built-in timer, and second, automatic walking, can display the standard time (intelligent control system, digital display), memory times:20 times. (3) The supply voltage of this product is DC6V.
Scope of application:
(1) Places with explosive gas and flammable medium.
(2) Explosion-proof mark: ExedIIBT4.

Mechanical Pig Indicator Instructions:

(1) 1) First, we need to unscrew the battery box cover and place two batteries according to the polarity shown in the figure. When done, tighten the battery case cover.
Battery compartment

(2) Turn on the panel power supply. The display window will display the scheduled time. Then press the “SET” key on the front panel to adjust the time. The number waiting to be adjusted starts blinking. Then continue to press the “Set” key, flashing digits to move to the right. Next, press the “Time Adjustment” button to adjust the time. When you’re done, press the “Set” button until the last digit ends (no flashing numbers).

(3) Because we need to observe the time or adjust the time in our work, we can press the “Display” button, and the clock display will light up. Then you can look at it or adjust it.

(4) Enter the test state:

In the test state, the clock runs accurately when the pig is. When passing, the display will show the elapsed time and stop running elapsed time, the time display will stop running and show the elapsed time of the pig, and this state will remain until the power connection is turned off.

(5) Restart: Turn on the power switch again, and the device will re-enter the testing state.
(6) The mechanical part resets automatically.
(7) Precautions

We cannot reverse the positive and negative poles of the power supply.

Do not hit the display window with heavy objects during installation. We need to replace the new battery for use.

Be sure to remove the battery after use.

Technical characteristics of mechanical transmission part:

1. Design pressure: 15MPa.
2. Operating temperature: -20-120°C.
3. Transmission medium: oil, water, natural gas, and other non-corrosive fluids.
4. Pipeline material: A: Various metals with good welding performance.
