In this article, we will introduce the calibration of gas detectors.

Solid state relay, short for SSR, is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control terminal and the load terminal. The input end of the solid state relay uses a tiny control signal to directly drive a large current load. So, how to maintain a solid state relay?

The float level switch is simple in structure, easy to use, stable in performance, long in service life, and easy to install and maintain. It is almost suitable for liquid level measurement and control in various industrial automation process control, and is widely used in petroleum, food, chemical, water treatment, liquid level measurement, control and monitoring in the fields of pharmacy, electric power, papermaking, metallurgy, ships and steel furnaces.

There should be no obstacles in the area radiated by the emitted ultrasonic beam between the emitting surface of the ultrasonic liquid level sensor probe and the surface of the medium to be measured. Therefore, the installation should be avoided as far as possible from the internal facilities, such as brackets, on-site equipment and so on. When installing the level sensor, the sensor must be kept at a certain distance from the tank wall, and the transmission direction of the transducer should be perpendicular to the liquid surface as much as possible.

Have you ever dropped a bunch of nails or screws in your yard and thought, "How can I find all these things?" Magnets to the rescue! Magnet cleaners use magnets to pick up ferrous materials like nails, screws , nuts and bolts. They are very useful in the house or workplace to help prevent punctures or damage to machines. But what should we pay attention to when we buy magnetic sweeper? I hope the following points can help you.

Air operated diaphragm pump is a new type of conveying machinery, and it is the most novel type of pump at present. Using compressed air as the power source, it can absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. However, many customers have some problems in the process of using the AODD pump. Then, we will troubleshoot the air diaphragm pump next.

A breaker which used vacuum as an arc extinction medium is called a vacuum circuit breaker (vcb breaker). In this circuit breaker, the fixed and moving contact is enclosed in a permanently sealed vacuum interrupter. The arc is extinct as the contacts are separated in high vacuum. It is mainly used for medium voltage ranging from 11 kV to 40 kV. In this article, we will introduce the routine maintenance of vcb circuit breaker.

Sewage pump is a pump and motor connected, and at the same time into the liquid pump products, compared with the general horizontal pump or vertical sewage pump, sewage pump compact structure, small footprint, easy installation and maintenance. In this article, we will introduce two kinds of technology of submersible sewage pump. The so-called auxiliary impeller hydrodynamic seal refers to the installation of an open impeller in the opposite direction near the back cover of the impeller of the sewage pump.

The working principle of electromagnetic relay is that when the electromagnet is energized, the armature is sucked down to make the two contacts, and the working circuit is closed. When the electromagnet loses its magnetism, the spring pulls the armature up, cutting off the working circuit. It is usually used in automatic control circuits. It is actually an automatic switch that uses a smaller current to control a larger current, so it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

If you own a building with an emergency generator electrical system integrated into its frame, routine automatic transfer switch maintenance is critical to ensure that you can function properly while utilizing the system. Automatic transfer switches monitor the voltage levels of the building's normal power supply and switch to emergency power when these voltage levels fall below a certain preset threshold. If a particularly severe storm or rolling blackout disrupts your main power source, an automatic power transfer switch will seamlessly and efficiently activate your emergency power system. So how do you test the performance of auto transfer switch?

What is the maintenance method of rubber sheet? Rubber plate itself has a certain weight, has a good grip, can be directly attached to the ground, generally do not need glue fixed.
