Basic Functions of Spring

• Cushioning, absorbing, or controlling of energy due to shock and vibration. example: Car
• Springs or railway buffers
• To control energy, springs-supports, and vibration dampers.
• Control of motion, and maintaining contact between two elements (cam and its follower)
• Creation of the necessary pressure in a friction device (a brake or a clutch)
• Restoration of a machine part to its normal position when the applied force is withdrawn (a governor or valve). A typical example is a governor for turbine speed control. A governor system uses a spring-controlled valve to regulate the flow of fluid through the turbine, thereby controlling the turbine speed.
• Measuring forces, spring balances, gages
• Storing of energy, in clocks or starters, the clock has the spiral type of spring which is wound to the coil and then the stored energy helps gradual recoil of the spring when in operation.

Materials Used for Spring: One of the important considerations in spring design is the choice of the spring material. Some of the common spring materials are given below.

• Hard-drawn wire: This is cold drawn, cheapest spring steel. Normally used for low stress and static load. The material is not suitable at subzero temperatures or at temperatures above 120°C.
• Oil-tempered wire: It is a cold drawn, quenched, tempered, and general purpose spring steel. However, it is not suitable for fatigue or sudden loads, at subzero temperatures and at temperatures above 180°C. When we go for highly stressed conditions then alloy steels are useful.
• Chrome Vanadium: This alloy spring steel is used for high stress conditions and at high temperature up to 220°C. It is good for fatigue resistance and long endurance for shock and impact loads.
• Chrome Silicon: This material can be used for highly stressed springs. It offers excellent service for long life, shock loading and for temperature up to 250°C.
• Music wire: This spring material is most widely used for small springs. It is the toughest and has highest tensile strength and can withstand repeated loading at high stresses. However, it cannot be used at subzero temperatures or at temperatures above 120°C. Normally when we talk about springs we will find that the music wire is a common choice for springs.
• Stainless steel: Widely used alloy spring materials.
• Phosphor Bronze / Spring Brass: It has good corrosion resistance and electrical conductivity. That’s the reason it is commonly used for contacts in electrical switches. Spring brass can be used at subzero temperatures.

Helical spring:

Springs are classified according to their shape.

• The spring can be a helical coil of a wire, a piece of stamping or a flat wound-up strip
• The most popular type of spring is helical spring
• The helical spring is made from a wire, usually of usually of circular cross-section, which is bent in the form of a helix
• There are two types of helical springs – compression spring and extension spring.

The Imm controller is a multi-functional controller which incorporates a microcontroller, making it a most versatile and cost-effective solution, that is designed to best suit the automation needs of all injection molding machines.

Basically, an all-in-one control system developed especially for the automation of plastic processing machines, e.g. injection molding machines. The word all–one control system includes I/Os, control, visualization, networking, and expandability.

The ULV CPUs (ultra low voltage) integrated with a particular cooling system, helps the system to operate in harsh environmental conditions.

The Analog Interrupt capability with threshold and fast counter 32 Bits specially developed in particular for injection molding machines.

We at N2S Technologies Pvt Ltd are supplying the following series of Injection Moulding Machine Controllers that ensure high productivity.

• Induction Motors.
• Squirrel Cage.
• Slip-Ring.Gear motors use either AC (Alternating Current) or DC (Direct Current) power. In most cases, the gear reducer is intended to multiply the available output torque without increasing the power consumption of the motor while maintaining a compact size.Simply put, a gear motor is an electric motor coupled with a gearbox. In most cases, the addition of a gearbox is intended to limit the speed of the motor's shaft and increase the motor's output torque.

On a bench or in a system, Keysight variable DC power supplies are ready for your application, offering optimal voltage, current, capability and performance choices.

This video will help you pick the correct variable DC power supply by understanding the critical characteristics you should consider in your selection process. Key aspects of DC power supplies include available power, noise requirements, programming accuracy, available software, and more.

Due to its innovative design, the VTQ air flow sensor element is very robust and highly insensitive to pollution, which leads to outstanding long-term performance. 

The measured data is available either on an analogue voltage or current output, user selectable, or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol.

The enclosure design and the mounting flange included in the scope of supply allow for easy installation or replacement. The configuration and adjustment of the EE650 can be comfortably performed on the electronics board or via digital interface.

Forgetting to order a part could leave a service intervention incomplete. The follow-up maintenance this entails will lead to extra downtime and all the associated costs. As your original equipment manufacturer, we know exactly which parts are needed for every intervention. They come as a single air compressor kit with the quality assurance of genuine Atlas Copco compressor parts.

Generic spare parts are not made specifically for your compressor or vacuum pump, so the integrity of your equipment will be at risk. Non-genuine parts are also likely to have a shorter lifetime and increase the risk of lower compressor performance and higher energy consumption. Genuine parts guarantee optimal air quality and performance.

Our service kits offer multiple administrative shortcuts. First of all, you don’t have to spend time on selecting the right parts for the next service intervention. Ordering your parts is reduced to a single item. Follow-up is just as easy.

A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.

Another type of pressure switch detects mechanical force; for example, a pressure-sensitive mat is used to automatically open doors on commercial buildings. Such sensors are also used in security alarm applications such as pressure sensitive floors.

A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors.^[1]

Commercial thermocouples are inexpensive,^[2] interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degree Celsius (°C) can be difficult to achieve.^[3]

Thermocouples are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. Thermocouples are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered appliances.
