The piston pump is a type of positive displacement pump, wherein said high pressure seal with said reciprocating piston. Piston pumps can be used to transport liquids or compressed gases. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong influence on the flow rate. Piston pumps can also handle viscous media and media containing solid particles. This pump type functions through a piston cup, an oscillating mechanism (where a downward stroke causes a pressure differential), and a filled pump chamber (where an upward stroke forces the pump fluid out for use). Piston pumps are typically used in scenarios where high, consistent pressure is required, as well as in water irrigation or delivery systems.

With the development trend of rail transit manufacturing industry, the maintenance quality and efficiency of rail transit vehicles and other mechanical equipment are required to be higher and higher. Because of the characteristics of industrial endoscope nondestructive testing technology, it has become an important testing tool in the industrial field. Industrial endoscopes can be used for visual inspection in special environments, such as containers, pipes, the interior of difficult-to-disassemble equipment, inner surfaces with narrow gaps, or areas that cannot be directly observed by human vision. Its application in the development, manufacture, maintenance, inspection and quality control of rail transit vehicles mainly includes the following four aspects.

Electromagnetic relay (EMR) is a kind of electrical relay that works in the effect of the suction between the magnet core and the armature in the input circuit. In other words, electromagnetic relay works in a way of driving the movable part in the magnetic circuit by the electromagnetic suction produced by the control current going through the coil, to achieve the function of contact open, closed and conversion.

An electromagnetic relay is a double-blade, double-throw relay that uses 2NO+2NC contacts to control a larger current. In the operation demonstration, we use 4 bulbs (220V), a power supply, a push-button switch, and the relay to show you how it works in a more visual way. ATO-HH52PL series electromagnetic relays are reliable and easy-to-install drives with powerful load capacity and compact size.

The hot wire anemometer is a type of anemometer that converts the flow velocity signal into an electrical signal, and can also measure fluid temperature or density. The length of the hot wire is generally in the range of 0.5 to 2 mm, and the diameter is in the range of 1 to 10 microns. If a very thin metal film instead of a metal wire, which is called a hot-film anemometer. The function is similar to that of a hot wire but is mostly used to measure the flow rate of liquids. 

For current signals, if the equipment has an independent power line, the signal output it provides (such as 4-20 mA) is active signal; If the device has no independent power supply, the signal it provides is passive. The output signal of three-wire instrument and four-wire instrument is active signal, and the output signal of two-wire instrument is passive signal. In this article, we will introduce the passive and actice signal.

A wind Meter (Anemometer) is an instrument for measuring airflow speed, which can be widely used in various fields, such as electricity, steel, petrochemical, energy-saving and other industries, in daily life, many industries need to use the wind anemometer, such as fan manufacturing, sea fishing industry, extraction and exhaust heating systems, etc., are required to use the anemometer for wind speed, wind temperature, wind measurement to ensure normal work.

The flow velocity measurement range from 0 to 100 m/s can be divided into three zones: low velocity: 0 to 5 m/s, medium velocity: 5 to 40 m/s, high velocity: 40 to 100 m/s. The anemometer's thermal probe is used for measurements from 0 to 5 m/s; the anemometer's rotor probe is most effective for velocities from 5 to 40 m/s; and the use of a pitot tube gives the best results in the high velocity range. An additional criterion for the correct selection of an anemometer flow probe is the temperature, which usually reaches about +-70°C for thermal sensors. Special anemometers have runner probes up to 350C. Pitot tubes are used above +350°C.

Linear actuators convert the rotary motion of the motor into a straight line. Traditional motors move in a circle, while linear actuators move forward and backward. Push and pull actions allow the device to slide, tilt and lift items with the push of a button. The design provides the operator with accurate and precise control over production. Fluid motion means linear actuators require minimal maintenance over their lifetime and are naturally energy efficient. They are easier to install, cost less and take up far less space than their hydraulic or pneumatic counterparts.

The wind speed test has the test of average wind speed and the test of turbulence component. The thermal anemometer is to test the average wind speed. The methods of testing the average wind speed are thermal, ultrasonic, impeller, and skin dragging tube, but in these methods, the anemometer is using the principle of heat dissipation. Below, a description of these types of anemometers is given.

Peristaltic pump is also called peristaltic metering pump, constant flow pump, peristaltic hose pump. A peristaltic pump is a liquid transmission device that can control the flow rate. By repeatedly compressing the elastic tubing, the liquid in hose moves in a certain direction, and its flow rate is determined by the diameter of tubing and the compression speed. The liquid is delivered by alternately squeezing and releasing the elastic delivery hose of the pump. In this article, we will introduce structure, working principle and selection of peristaltic pump.

Electrolytic capacitor is a kind of capacitor, the metal foil is the positive electrode (aluminum or tantalum), the oxide film (aluminum oxide or tantalum pentoxide) close to the positive electrode is the dielectric, and the cathode is made of conductive material and electrolyte (the electrolyte can be liquid or tantalum pentoxide). Solid) and other materials together, because the electrolyte is the main part of the cathode, so the electrolytic capacitor is named.
