JWXC-7 type infinite relay is a relay widely used in railway signal technology, called signal relay, and it is an important part of railway signal technology. It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system. The reliability of the relay action directly affects the reliability and safety of the signal system.
Product Usage
The JWXC-7 type infinite relay is used as a general purpose and air-proof step-down relay in the signal circuit.
Applicable environment
The applicable environment of the relay is:
a) Ambient temperature: -40~+60;
b) Relative humidity: not more than 90% (temperature +25);
c) Air pressure: not less than 70kPa (equivalent to below 3000m above sea level);
d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;
e) Working position: horizontal;
f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.
product structure
Infinite relay is the typical structure of AX series relay, which is composed of electromagnetic system and contact system. The electromagnetic system includes coils, iron cores, vehicle irons and armatures. The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil. The use of dual coils is to enhance the flexibility and flexibility of the control circuit, which can be controlled by a single coil or a series of double coils according to the circuit needs. The armature is fixed on the blade of the yoke by a butterfly-shaped steel wire, which is flexible in movement. There is a heavy hammer in the transmission part of the Yantie to ensure that the relay armature returns reliably by gravity. The number of weights installed is determined by the structure of the relay contact system, and should be able to ensure the reliable release of the relay. A stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit of the relay, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure that the relay falls reliably. The iron core, vehicle iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence.
The JWXC-2.3 type infinite relay is used as a DC track relay in the signal circuit.
Features
1. The relay is a heavy elastic DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.
2. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay.
4. The contact system is composed of ordinary contacts, and there are four groups of ordinary contacts for switching on and off.
5.The rated current of the relay is 280mA DC.

Rosemary (Rosmarinus officinalis) is a woody, perennial herb with fragrant evergreen needle-like leaves. It is native to the Mediterranean region. It is a member of the mint family Lamiaceae, which also includes many other herbs.
The name rosemary derives from the Latin name rosmarinus, which is from "dew" (ros) and "sea" (marinus), or "dew of the sea" — apparently because it is frequently found growing near the sea.
Description
Forms range from upright to trailing; the upright forms can reach 1.5 m (5 ft) tall, rarely 2 m (6 ft 7 in).
The leaves are evergreen, 2/4 cm (0.8/1.6 in) long and 2/5 mm broad, green above, and white below with dense short woolly hair.
Flowering, very common in a mature and healthy specimen, blooms in summer in the north; but can be everblooming in warm-winter climates and is variable in color, being white, pink, purple, or blue.
The rosemary plant is light blue and blooms from March to May. For most tonics and recipes the rosemary leaves are use more often than the flowers or the rest of the plant. Rosemary is a bushy type of evergreen that can grow six feet or higher. The tree contains leaves that are stiff and leathery.
Solid type: white powder or granules, hygroscopic, readily soluble in water. The aqueous solution may absorb CO2 and form aluminum hydroxide precipitate. Addition of NaOH is required to increase stability.
Liquid type: transparent slurry, stable during storage life. Prolonged stay of diluted aqueous solution may cause aluminum hydroxide precipitate.
Use:
In the construction process, it can be used as leaking stoppage agent combined with the sodium silicate.
In paper-making, this product can mix with aluminum sulfate to be a good filling agent.
In water treatment, it can be used as additive of purifier.
