Fisher Fisher locator may encounter the following kinds of failures in the process of use, don't be nervous in the face of failures, we just need to find out the cause of the failure The fault can be solved very well, and the following is a summary of what we have done for you. 1. Fisher Fisheldine ...

Fisher valve positioners use an I/P electrical converter that converts an electrical signal into a gas signal. So what do we need to pay attention to during the conversion process? How do I make the switch? Here's how it goes. The I/P electrical converter of the Fisher valve positioner is made from a gas source through a constant throttle ...

The vibration of the control valve is generally divided into two states, one is the overall vibration of the control valve, that is, the entire control valve frequently vibrates on the pipeline or base. The other is the vibration of the spool of the regulating valve, which can be seen from the frequent movement of the valve stem up and down, and the following are the causes of these two vibrations and their treatment Measure...

1. Interfacial leakage of mechanical seals: a kind of leakage between the surface of the sealing ring (oil seal, sealing ring, gasket, packing) and the surface of the contact parts. Such as leakage between the flange and the gasket, between the packing material and the shaft or the packing box. 2. Penetration and leakage of mechanical seals: medium ...

Peculiarity: Merit: 1. Ultra-miniaturization can be realized 2. Wide range of output torque 3. It is easy to control, and can freely use various signals such as DC, AC, short wave, pulse, etc., which is suitable for amplification, memory, logical judgment and calculation shortcoming 1. Complex structure 2. Mechanical ...

The power of Fisher is huge, the power of example is infinite, in today's market to achieve a better survival of our goods, we must have the characteristics of our own products, from the development of our valve industry, in the current market, such equipment ...

Electric actuator, also known as valve electric device, it is a name in different industries, called valve electric device in the industrial pipeline valve industry, and called electric actuator in the instrument industry, but now there is no clear distinction in the industry.

This article today gives you a detailed introduction to the basic information of the United States Fisher control valve nameplate, the information on the Fisher nameplate, you can click on the attachment to view. location + number 865 represents Tianjin Fisher factory production, 382 represents Malaysia factory production, and of course ...

In the event of a malfunction, focus on which parts to inspect 1. Valve body wall For the control valve used in the occasion of high pressure difference and corrosive medium, the inner wall of the valve body is often affected and corroded by the medium, and the pressure resistance and corrosion resistance must be checked. 2 seats When the regulating valve is working, due to the infiltration of the medium...

Seven common problem solutions for pneumatic butterfly valves: 1. The butterfly valve is installed in the pipeline, and the best position is vertical, but it cannot be reversed. 2. It is recommended to use the special flange of the butterfly valve, that is, the HGJ54-91 socket welded steel flange. 3. Butterfly valve stem installation ...

When the pressure gauge is connected to the pipeline, a bend should be added between the pressure gauge and the pipe connection. Why is that? What does this do? Let's take a look! This thing that connects the pressure gauge and the pipe is the pressure gauge bend (also referred to as the gauge bend), which is officially called the buffer pipe. ...

In the past operation of natural gas pressure regulating system, terminal equipment such as pressure regulating cabinets, pressure regulating boxes, and pipelines in the distribution network have always been a relatively weak part of the monitoring means. As a result, problems such as non-troubleshooting and emergency gas shutdown accidents also make consumers and operators feel painful. Meanwhile...
