1. The pipeline of the pipeline centrifugal pump is matched Some users of pipeline centrifugal pumps think that this can improve the actual head, but in fact, the actual head of the pump = total head - loss head. When the pump model is determined, the total head is fixed; The loss head is mainly due to the resistance of the pipeline, and the smaller the pipe diameter ...

Intelligent communication mode: The obvious feature of intelligent valve positioner is intelligent communication. For our process industry ...

United States Fisher Pneumatic Valve Positioner is the primary accessory to the Pneumatic Control Valve, which is a single-output valve positioner. It describes the main features and common faults of the valve positioner, as well as the treatment methods and protection methods. 1. The main features of the locator (1) Large-diameter pilot ...

Cavitation: When the static pressure of the liquid entering the first-class impeller in the pump is lower than or equal to the saturated vapor pressure at this temperature, the liquid vaporizes and produces bubbles. This vaporization and condensation produce ...

Butterfly valve is used in industry, its characteristics can withstand high temperature, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. The butterfly valve is a circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid.

Use and Maintenance: 1. It is recommended that the user unit appoint a special person to be responsible for the use and maintenance 2. Regular maintenance 1-2 times a year is the best way for the solenoid valve to work reliably and live long. The following 4 conditions inside the solenoid valve are the reasons that hinder the normal operation of the solenoid valve and shorten the life of the solenoid valve. ⑴ ...

Gate valves usually have single ram, double ram, wedge, parallel and other structural designs, among which wedge double ram (Z42, Z62 series) and wedge elastic ram (Z40, Z60 series) are widely used, the former when the gate is closed, the gate automatically fits the valve seats on both sides, and automatically compensates the processing position of the wedge angle.

United States fisher DVC6200 intelligent valve positioner provides customers with a higher quality and accuracy of the digital instrument positioner, the positioner can realize online diagnosis of the valve, the online monitoring valve operation data and information to retain and transmit to the DCS system for real-time monitoring and ...

First of all, we must know a concept, what is a conditioning valve, that is, a control valve. Control devices for regulating fluid flow in industrial process control systems. It can adjust the process parameters such as pressure, temperature, flow rate, and liquid level of the fluid by manipulating the fluid flow Conditioning valve composition: valve body ...

Sensor - A device or device that can sense a measured pattern and convert it into a usable output signal according to the rule. It is generally composed of sensitive elements and conversion elements. A simple sensor is composed of a component (which also serves as a conversion element), which directly outputs electricity when it senses the measurement, such as thermoelectric ...

In the valve design or use experience, the lifting valve packing is mostly asbestos packing or graphite packing or PTFE V-type packing, but these packings are limited by the number of valve opening and closing, that is, with the increase of the number of valve opening and closing, the packing will wear out, and the gap will gradually increase, to a certain number of times.

Electric control valves have been more and more widely used in various industrial control systems due to their high control accuracy, convenient installation and commissioning. However, in the process of use, there are also some problems that plague field instrument personnel, that is, the problem of valve leakage. Here we will explore the electric ...

Zornio, a veteran automation and software leader, drives Emerson's innovation and technology strategy ST. LOUIS (November 29, 2022) – Emerson (NYSE: EMR), a global leader in automation technology and software, has appointed Peter Zornio as a ...

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...
