Symbol Standart P&ID

    Symbol Standarisation P&ID For Industri Standard piping and instrument symbols are detailed diagrammatic documentation that provides a set of forms & standards for documenting P&IDs and PFDs, including standard shapes for instruments, valves, pumps, heat exchangers, mixers, crushers, vessels, compressors, filters, motors and other connection forms. Here are some symbols on P&ID : So, those are some of the symbols that we will often see when reading piping & instrument diagrams. May be useful.

Genset Heating Procedure

Genset Heating Standard Procedure Genset is one of the equipment that functions to convert mechanical energy or rotation of the rotor into electrical energy. The generator has two main parts, namely the motor generator and the generator engine (usually a diesel engine), both of which are connected by a shaft. The generator itself has two main parts, namely the rotor and stator. The stator is the stationary part, while the rotor is the rotating part. This generator works when the genset control panel receives input if the power source from PLN dies, then the PLC or ATS (automatic transfer switch) will give an order to the genset control panel to turn on the generator, this is done automatically. What if the generator has to be turned on manually, for example when heating the generator? Genset as one of the supporting utility facilities of a building must of course be maintained regularly, one of which is heating the generator as one of the genset maintenance procedures. To warm up the g

Text And Mtext In Autocad

The Difference Between "Text" And "Mtext" In Autocad And How To Convert It In operating AutoCAD we often encounter or use writing with the aim of providing information, showing something, etc. so that our drawings are easier to understand. To write in AutoCAD, we know that there are two options, the first is "TEXT" and the second is "MTEXT". So what are the differences between the two? TEXT For "text" itself we can call it single text or single writing. So if we use "text" we can only write one sentence in one piece of text. The disadvantage of this "text" is that it doesn't have any editing menu, we can't adjust or adjust our needs in this paper, instead we must first enter the properties menu. This means that from this "text" we can only edit the written content. To use this "text" we can use the command type "DT" then press enter. MTEXT As for "mtext" itself is an ab


Maintenance In the engineering we are certainly no stranger to this term, yes maintenance. Maintenance can be applied both in the industrial world (to maintain production machines and building utilities), construction (to maintain construction equipment) or even in household appliances. No machine or tool can work for a long time without proper maintenance. Well, in an industry, maintaining machines in good condition is very important. So what types of maintenance are there in an industry? And why is maintenance so important? Maintenance Definition Maintenance can be interpreted as the work of maintaining something (machine etc.) so that it is in good condition. As for maintenance or maintenance in industry is the practice of keeping equipment and machinery in good working condition for. Maintenance can produce a quality product. The purpose of industrial maintenance is to increase the life of industrial equipment, keep all plant assets in good condition at the lowest possible cost. In

Metal Material Classification

Metal Classification Metal is one of the most abundant materials on earth. The need for metal is very high, especially in the industrial sector, especially the automotive industry and of course the construction world. On this occasion I will discuss a little about metals, ranging from classification etc. Metal Metals are divided into two main categories, ferrous metals and non-ferrous metals. 1. Ferrous metal is a metal containing the element iron (Fe), for example iron and steel. 2. Non-ferrous metals are metals that do not contain iron (Fe), for example aluminum, copper, gold, silver, tin, bronze etc. Between ferrous metals and non-ferrous metals are distinguished by their composition. For ferrous metals, we usually call them metal, for ferrous metals, namely iron and steel, they are divided into several types, among others. Iron Iron or can be called cast iron is divided into several types: 1. Grey iron 2. Malleable iron 3. Ductile iron 5. Compacted graphite iron 6. Austempered duct

Compressor Type

Compressor Compressor is one of the mechanical equipment that serves to increase the pressure of the air by reducing its volume. The way the compressor works is almost the same as a pump, both of which function to increase the pressure of a fluid, only if the pump functions to flow fluid in the form of a liquid, while the compressor functions to drain the fluid in the form of a gas. Both flow fluids in a compressed pipe system. Because the gas or gas has compressible properties, the compressor compresses the air by reducing the volume of the air. Compressor Type 1. Reciprocating Compressor Reciprocating compressors use pistons that move back and forth to compress or compress air, this piston functions to suck air from the atmosphere through the suction valve and press it into the pressure valve. This piston is driven by a crankshaft or shaft, this shaft is connected to the driving engine, usually an electric motor or diesel engine, between the driving engine and the piston shaft connec

Neutral Ground Phase Difference

In electrical distribution systems, especially AC current for low voltage electricity, we often find terms around phase, neutral and ground. What is the difference between these terms? Let's discuss them one by one. Phase For low-voltage electric current, the term for low-voltage phase is divided into 2, namely phase voltage 380 V and voltage 220 V. Before we discuss further about low voltage, let's first discuss what a phase is. Phase is part of the conductor or conductor of electricity that contains voltage. The difference between the 380 V and 220 V voltage is that if the 380 V voltage uses 3 conducting wires or other terms 3 phases, the 220 V voltage only uses 1 conductor cable or other terms 1 phase. The voltage of 380 V is obtained from measurements between phases with other phases, while the voltage of 220 V is obtained from measurements between phases and neutral. This measurement is carried out using a multitester. The 3 phase system was developed because it has the ad
