HQBBK-2010C Explosion proof Magnetic Control Travel Switch Induction Block

HQBBK-2010C Explosion proof Magnetic Control Travel Switch Induction Block

The travel switch HQBBK-2010C is used for controlling and limiting the spatial coordinates of lifting and transmission machinery in industries such as power plants, steel mills, construction, ports, and mines. The limit switch consists of a high-precision large transmission ratio reducer and a mechanical memory control mechanism synchronized with its output shaft, as well as sensors. The limit switch has the characteristics of small size, multiple functions, high precision, adjustable limit, strong universality, and easy maintenance, installation, and use adjustment. It is widely used in construction machinery.

The travel switch HQBBK-2010C adopts a non-contact memory holding function and is a passive valve position signal feedback device. With its unique technology, excellent quality, and comprehensive design capabilities in technology and process, this product has been widely used in thermal workshops, chemical water treatment workshops, ash removal workshops, and electrical workshops of thermal power plants, replacing and updating various types of machinery.

The LED indicator displays synchronously with the contact point, making the valve operation status clear at a glance and allowing for remote observation, reducing the labor intensity of the staff.

Installation connection method

Adopting clamping installation, easy debugging and quick installation

The non-contact+holding function uses the magnetic actuator on the piston inside the cylinder to trigger the transmitter, and there is no mechanical wear during the action process. The working status signal has a hold function.

One time installation without on-site maintenance, no need for adjustment or maintenance during the service life of the main equipment

Passive switches are directly connected to the circuit, and the signals emitted can be displayed locally or directly input into the computer. The state is stable, and there is no need for external power supply. The signal acquisition is convenient

The explosion-proof magnetic control travel switch HQBBK-2010C uses a reed switch and a magnetic steel in combination inside the induction block, which has the characteristics of high melting point and wear resistance. Sealing the reed switch and magnetic steel inside the shell can effectively prevent impact and has strong resistance. The magnetism of the small magnetic steel is not sufficient to attract the spring pieces inside the reed switch, and the switch remains in a normally open state. When the magnet approaches the switch from far to near in one direction, the spring contacts inside the reed switch are attracted. When the magnet leaves, the state of the reed switch is maintained because the magnet inside the switch is magnetized at the same time. When the magnetic steel approaches the switch again from the opposite direction, it is magnetized in the opposite direction, causing the magnetism to decrease and causing the reed switch spring to bounce open due to its elasticity, and the contact to also disconnect. The magnetic proximity switch is used in conjunction with the KY35 series magnetic steel, which is directly installed on the detected moving object. When the magnetic steel passes back and forth through the switch, it drives the switch to work. Several detection point switches on the same motion trajectory only require one magnetic steel.

Structural form:

Travel switches can be divided into direct acting, roller type, micro acting, and combination types according to their structure;

Direct acting travel switch:

The principle of action is similar to that of a button, but the difference is that one is manual and the other is caused by the collision of moving parts' blocks. When the collision block on the external moving part presses the button to make its contact move, the contact will automatically reset under the action of the spring when the moving part leaves.

Roller type travel switch:

When the blocking iron (collision block) of the moving machinery presses against the roller of the travel switch, the transmission rod rotates together with the shaft, causing the cam to push the collision block. When the collision block hits a certain position, it pushes the micro switch to move quickly. When the stopper on the roller is moved away, the reset spring resets the travel switch. This is a single wheel automatic recovery travel switch. However, the dual wheel rotary travel switch cannot automatically reset. It relies on the reverse movement of the moving machinery, and the stopper collides with another roller to restore it.

In actual production, the travel switch is installed in a pre arranged position. When the module installed on the moving parts of the production machinery collides with the travel switch, the contact of the travel switch moves, realizing the switching of the circuit. Therefore, a travel switch is an electrical device that switches circuits based on the travel position of moving parts, and its working principle is similar to that of a button.

The travel switch HQBBK-2010C is a new type of switch used to control the travel and limit protection of mechanical equipment in the development of automation technology. This switch has strong resistance and is suitable for use in harsh hazardous areas such as coal mines without gas and dust. It is used as a deceleration point for shaft hoists, limit stop, over roll protection switch, loading and unloading gate, air door control and roadway transportation, mine car counting, trolley machine, and is also widely used in power plants, steel, mining, machinery, light industry, metallurgy, chemical industry, textile and scientific research departments.
