Process and Instrumentation Drawing Symbols and Their Usage Process and Instrumentation Diagrams use special shapes to represent different types of equipments, valves, instruments and pipelines. Process and Instrumentation Symbols – Equipment Pumps and tanks come in a variety of designs and shapes. You have both abstract symbols and simulation images to choose. Learn the basic knowledge about piping and instrumentation diagram. Pump is a mechanical device using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires. The symbols for pumps may closely resemble those for compressors. Centrifugal pump is rotodynamic pump that uses a revolving impeller to add to the force and pressure of fluids.
Diagrams –Typical Pump Installations
Most of the text is specific to the units found on early Mustangs, Falcons, Fairlanes, Galaxies and their Mercury counterparts, but also generally applies to earlier and later versions also. This style unit was used on Fords with “power assisted” steering where hydraulics connected to the steering linkage was used to help turn the car. Over the years it has developed a reputaion for looseness and fluid leakage, but those are not flaws in the design itself but due to age, abuse and neglect.
A properly built, adjusted and maintained system will provide many thousands of miles of trouble-free operation. There are a few things that owners of new reproduction and rebuilt units should be aware of.
Anchor windlass is a large deck on the ship machinery, used to receive, put anchors and anchor chains. Windlass is usually installed in the ship stern first on the main deck for the ship weighed anchor, anchor mooring during the event.
What is Deck Machinery? The introduction of winches The winches are the small light weight lifting equipment to use the wire rope or chain rounding rolls or to upgrade or drag the heavy objects. The winches have the following features: And they are widely used in construction, water conservancy, forestry, mines, docks and other materials, also can make modern electronically controlled automatic operation line equipment.
The winches’ capacities range from 0. The winches which are higher than for the large tonnage of 20 tons can be used alone, but also as a component part of crane, road building and mine hoist and other machinery. Because of simple rope around a large, mobile home convenient the winch are widely used. The main technical in dictators are rated winches load, to support the load, speed rope, rope capacity and so on. In accordance with the power, the winches can be divided into hand winches, electric winches, and hydraulic.
From the use of the classification can be divided into construction and boat winches In accordance with the functions, the winched can be divided into: Windlass is usually installed in the ship stern first on the main deck for the ship weighed anchor, anchor mooring during the event. Windlass and winch normally used in conjunction. Windlass mainly by the base, frame, anchor chain wheel, brake, sprocket, transmission, electronic control systems except for manual windlass and other components, electric windlass with electric motors, hydraulic windlass with hydraulic pump station.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity.

How to Repair a Buzzing Valve Solenoid Buzzing solenoids are usually caused by insufficient voltage reaching the valve solenoid. Unfortunately there are many things that can cause insufficient voltage. To determine what the problem is requires testing for each of the possible causes. First off, what’s a valve solenoid? The valve solenoid is the small device attached to the valve that the wires lead to. It is what makes the valve open and close when an electrical signal is transmitted to it by the irrigation controller.
The solenoid is actually a electro-magnet that operates a plunger, which serves as a pilot valve, but that is not important for what we want to do here. It is normal for the solenoid to make noise, it clicks when the valve is turned on or off. It also is normal for a very soft buzzing sound to be heard when the valve is activated, but you should not be able to hear it unless you put your ear near it. If you can easily hear it buzzing, that is not normal.
Orbit Sprinkler valve manifold combines several valves in a single unit. Whether you have a simple sprinkler system or a complex one with five or more circuits, each circuit must be controlled by its own sprinkler control valve. Arrange your system so that each circuit controls a specific portion of your yard. For example, one may be used to control an array of micro-sprinklers or drip emitters for a flowerbed and containers.
Measure your water flow rate to determine the size pipe that should run from your supply source to the control valves.
1)What is QA/QC? Ans> QA/QC means Quality assurance/Quality control the purpose of this (QA/QC) is to establish the sequence of requirement for the quality of .
Grab yourself a stubby, get comfortable and read into the fascinating world of Datsun and other engine valve train operation. Once read a couple of times you will likely understand more about camshafts, valve train geometry and the things affecting them than most of your mates and some automotive engineers as well. Datsport has been extremely fortunate to be permitted to reproduce what is widely recognised at being the best article ever written on camshafts and their operation.

When it comes to instrumentation its all about safety. Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity.
There are two types of hook-up drawing: A good designer can also read whether the instrument tapped in gas service or liquid service. Installation detail specification will also specify items that should be utilized and factor that should be considered in one installation The purpose of Instrument Hook Up Drawing As stated earlier, information of the requirement of bulk material is stated for installation on each sheet hence the bulk material required for the whole drawings could be summarized and tabulated in a document named Material Take Off.
During project construction phase, this drawing is also referred as a guidance of how to install the instrument properly.
Most shop manuals make it look easy, but that is true only if the parts you have to re-use are not damaged from rust or wear Before you consider or attempt a rebuild, there are some problem areas you should be aware of. This first part is not designed to scare you off from attempting your own rebuild well, maybe just a little , but to show you what you may encounter along the way.
I have done hundreds of control valve rebuilds and see these problems on a daily basis. These are the things not mentioned in any instruction sheet or shop manual. Many valves have been swapped off of different year and car models from junkyard cars and such.

OEM Considerations Compressor and Reservoirs In the drawing above, the compressor bottom left builds up air pressure as it passes through the air-dryer on to the supply reservoir. The D-2 governor on the compressor keeps the tractor air supply pressure between and PSI. The safety valve on the supply reservoir prevents the air pressure from exceeding PSI.
The supply reservoir feeds the other two tanks via a check valve. The check valve prevents the front axle service reservoir and the rear axle service reservoir from bleeding off pressure back to the other tank or into the supply reservoir if one of these tanks should suddenly loose air pressure. Double-check Valves Notice the double check valve dc-4 and the double check and brake light switch valve ds Both of these valve take supply air pressure from two different sources and share their use.
If one of the supplies drops pressure, then that supply is isolated from the other supply, and only the other supply provides air pressure to the shared port. The brake light switch activates with pressure from either source. Brake Pedal Valve The brake pedal value is two independent service brake valves in one. The top half provides service brake air pressure to the front axle. The lower half provides service brake air pressure to the rear axles. Both halves regulate the air pressure PSI to be relative to pedal movement.
More pedal movement results in more air pressure to the associated axle s.
