The working principle of impulse turbines is the same as that of reaction turbines in that they both use the force and reaction force principle of water flow and runner blades to transmit water flow energy to the runner, causing the runner to rotate and release mechanical energy. The main difference between impulse turbine and reaction turbine lies in the way water enters and exits the turbine, as well as the working principle of the water turbine.

In the field of liquid transportation, pneumatic diaphragm pump is a common and widely used pump type. Air-operated diaphragm pumps use compressed air or other gases to drive the pump's movement, rather than relying on electric motors or other traditional power sources. Because the pneumatic diaphragm pump does not rely on electricity, it can work in places with unstable or no power supply. Therefore, in some special working environments, such as the field, remote areas or explosion-hazardous areas, the pneumatic diaphragm pump is a reliable and safe liquid delivery solution. And it is also suitable for various corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Pneumatic diaphragm pumps are divided into pneumatic double diaphragm pumps and pneumatic single diaphragm pumps according to their structure. So what are the differences between pneumatic double diaphragm pumps and single diaphragm pumps?

In power systems, switches allow the system operators to disconnect or connect electrical circuits. Switches come in various configurations among which there are several specialized forms, such as relays and circuit breakers. Though in more precise terms, relays are controlling devices while circuit breakers are switching devices.

Pumps are machines that convey fluids or pressurize them, and are mainly used to convey water, oil, slurries, acid and alkali liquids, emulsions, suspensions, gas mixtures and liquid metals, etc. They are common conveying equipments in mining, chemical and metallurgical industries, and different pumps differ in their structural appearances, load-bearing capacity, service life and application areas.There are many types of pumps, but we will only discuss two of them here: screw pump and gear pump. Understanding the difference between them is important for the correct choice of the desired product, which can effectively improve the service life and performance of mechanical equipment.

Deep groove ball bearings and tapered roller bearings are two common types of bearings, which are widely used in a variety of industries. They are different in structural appearance, load capacity, service life, and application areas. Understanding the difference between them for the correct selection of bearings is of great significance, and can effectively improve the service life and performance of mechanical equipment.

A deep groove ball bearing is a type of rolling-element bearing that is widely used to support radial and axial loads in various applications. It consists of four main components: an inner ring, an outer ring, a set of steel balls, and a cage to hold the balls in place. There are many types of deep groove ball bearings, while we only discuss their main classification—single row deep groove ball bearing and double row deep groove ball bearings here.

Air motors can be divided into two types, piston air motors and vane air motors. These two motors have different advantages and are widely used in industry. We will introduce you to the different working principles and application scenarios of vane and piston air motors.

Whether in life or in industrial life, the use of motors is inseparable. In order to meet the needs of different industries, more and more types have gradually appeared on the market. But many users do not know how to choose when purchasing. In fact, to choose the right product, we must first compare different products. Let's take a look at the difference between a DC geared motor and a stepper motor.

Gate valve and globe valve are commonly used valves, but they are also two different valves. When purchasing, we need to distinguish the different characteristics of gate valves and globe valves to ensure later use. Gate valves and globe valves are widely used in our lives, so what is the difference between gate valves and globe valves?

Valves are pipeline accessories used to open and close pipelines and control flow direction, and play an important role in industrial production. There are many types of valves, and their specific functions are also different. Today we will understand the difference between globe valve and butterfly valve, let's take a look together.

There are many types of jacks, and different types of jacks have good performance in their own suitable fields. If you give a total score to the jacks, the most common ones are nothing more than hydraulic jacks and mechanical jacks, and different jacks are often being used for comparison. So today we mainly talk about the difference between hydraulic jacks and mechanical screw jacks.

There are many applications of valves in life, such as faucets, water heaters, gas, etc., all have valves. But there are many types of valves according to their structure, principle, application field and so on. Among them, globe valve and ball valve are common types, so what is the difference between globe valve and ball valve? In this article, ATO industrial automation will introduce the differences between globe valve and ball valve.

Absolute encoder refers to the absolute code within the precise measurement device (sensor), within the range of precise measurement, the specific position of all mechanical equipment has a unique corresponding relationship with the origin of the specific position of the machine in advance, any time accurate measurements do not rely on the history of previous measurements. Even without moving, the unique absolute code can be output directly.

In general, solid state relays are quite similar to the mechanical relays that have movable contacts. The main difference between both is the fact that there are no actual moving components in an SSR, just like the name suggests. Rather than relying on a physical contact moving to complete the circuit, solid state relays (SSR) employ optical semiconductor switching elements, such as diodes, thyristors, triacs and transistors. In this article, ATO automation will explore these two typical relays and find out more about their differences. 

AC circuit breaker is the main power control equipment of substation. Both DC circuit breaker and on-load voltage regulator refer to the transformer tap switch voltage regulation mode.  The difference is that the non-excited voltage regulator does not have the ability to change gears with load. We need to understand the difference between AC and DC circuit breakers from different aspects. In this article, ATO industrial atomation will explore the differences between the two.

Load cells are responsible for measuring the weight or force applied on a scale. In essence, load cells determine the accuracy of a weighing balance. There are two primary forms of load cells, analog and digital. In this article, we're gonna make a simple differentiation of both. Simply put, the difference between an analog and a digital load cell is how their signal is processed. They differ in three major ways: signal strength, signal content and data sample rate.

Angle valves and solenoid valves are two commonly used types of valves, especially for their long life and easy-to-operate intelligent control, which are widely used in projects. However, there are certain differences between the two products. Only by distinguishing the various characteristics can a better selection be made.

There is a wide range of cylinder types, and cylinder designs vary according to their application and end-use industry. These cylinder types differ in certain components. The more commonly used pneumatic actuators in manufacturing consist of a piston and rod moving within a closed cylinder and are designed to move in a straight line to provide linear motion. This type of linear actuator is used in various industrial sectors, factory automation and packaging, as well as transportation and life science applications. Single-acting cylinders and double-acting cylinders are common types of cylinders.

There is no difference between the butterfly valves themselves, the difference lies in their respective actuators and the applicable working conditions affected by the actuators. Among them, butterfly valves can be divided into pneumatic butterfly valves and electric butterfly valves, both of which are widely used in the market. These two butterfly valves are easily confused because of the difference in driving energy. This kind of valve with structural similarity is more likely to be confused in procurement and use, so buyers need to fully grasp the principles and advantages of the two. Here is a detailed introduction to the difference between them. Let's take a look.
