However, aluminum has low surface hardness and no wear resistance. In order to make the aluminum substrate satisfactorily practical as a conductive trolley wire, the â€œHâ€-shaped center beam is made into an upper arch type, and a stainless steel section with high wear resistance is embedded here according to a regular technical procedure. This "H" shaped stainless steel profile serves as the frictional transmission surface of the conductive block in the conductor. Its inserting technology ensures the tight integration of the stainless steel and the aluminum profile. The voltage introduced from the aluminum profile passes through the stainless steel body to keep it in close proximity. The conductive block in the conductive device transmits the voltage in the vicinity of the frictional point to ensure that the voltage of the hoisting machinery is continuously connected during operation.
HXPnR-H protective safety wire contact line equipment maintenance stated:
1. The equipment elucidates that: Before the equipment slides the wire, the angle bracket is fixed according to the equipment selected by the user, and the suspension spacing of the trolley wire is fixed. The required number of six-meter-long sliding wires is set at the equipment site. Suspension seat, and two joints jacket each one, at one end is equipped with an aluminum joint, when installing aluminum joints, it should be noted that only the aluminum rail can be extended into the joint of 1/2 to be reserved for another rail, the above operation When ready, hang a single wire on the bracket for full-line connection. When connecting, tighten the screws of each connector. When the total length of the trolley line exceeds 200 meters, elastic equipment shall be installed (elastic equipment is supplied by the factory at any time). When the incoming power line is connected, it can be connected at every 6 meters of the joint. Detailed connection method can refer to the front Connector equipment diagram.
When the device bends the line, the suspension interval should be shortened accordingly. The detailed scale can be determined according to the site conditions. In the device conductive device, the conductive device is first mounted on the matching square tube, and the appropriate orientation in cooperation with the trolley line is selected to be fixed on the electric device. Attention should be paid to the fact that the conductive device and the trolley line have a good tracking function. Outstanding touch ability, conductive device and trolley wire should be in the same vertical and horizontal direction.
2. Maintenance: The safety trolley line should be checked regularly during normal operation. Since electricity equipment is the primary production tool for each industrial and mining enterprise, slight fault will directly affect the production efficiency of the factory. When viewing the trolley wire, check whether there is any looseness and disengagement of a joint every 6 meters. When viewing the conductive device, you should check whether the moving part is flexible, the tension is not exhausted, the brush is worn, etc. ( The condition will affect the conductive function of the trolley conductor and the tracking function of the conductor. Adjustment shall be made promptly.)
During the renovation of holiday equipment, the conductive device is pulled out of the catheter and the wear status of the brush roller of the conductive device is inspected. If the protruding amount of the brush is smaller than the useful length of the rule, it must be promptly replaced. When the guide roller is deformed severely, it must be replaced to maintain the conductive device. The normal operation and the outstanding touch of the brush, and check the origin of the formation. Safe Slip Lines In all parts, brushes are only parts that will normally wear out.
Conductive slide wire along the length of the slide line with ABS plastic as a whole maintenance in addition to the lower part of the opening and the conductive device near the outside, and therefore the device does not show some of the conductive wire near the rear line, to bring great convenience to the equipment and repair, all together The maintenance of the plastic shell ensures that the trolley wire does not have the function of accumulating dust and rain, dew, ice, and snow. The connection between the guide rail and the guide rail is a special guide rail adapter that allows the guide rail and the plastic housing to extend into the same. Its end is also safe and reliable.
HXPnP, RH-type protective safety wire contacts, the main conductive body for the section of the aluminum profile, it is also known as energy-saving slide wire device, energy saving is relative to the main line of angle steel bar, the loss of power in the transmission process Greatly reduced. The electrical resistivity of aluminum is much lower than that of steel, and its specific gravity is small. Rolling and forming of aluminum material is based on securing a certain conductive cross-sectional area so as to improve overall rigidity and strength. However, aluminum has low surface hardness and no wear resistance. In order to make the aluminum substrate satisfactorily serve as a conductive trolley wire, an upper arch is formed in the middle beam, and a stainless steel section with high wear resistance is embedded here according to a regular technical procedure. This type of stainless steel profile is used as the frictional transmission surface of the conductive block in the conductive device. Its inserting technology ensures the tight combination of stainless steel and aluminum profiles, and the current introduced into the aluminum profile is passed through the stainless steel body to make it adhere to the conductive device. The guide block transmits the current in the friction touch, ensuring that the current of the hoisting machinery is continuously connected during operation.
Considering the power supply point of the safety wire contact line, the total capacity of the total number of power devices with the same cross-slip contact line, the mission operation system and the voltage drop value of the entire line length, and the environment should be considered. (The voltage drop calculation can be based on the front rail parameter table. Data accounting). Power supply usually has the following types for users' reference: 1 Single-end power supply; 2 Central power supply; 3 Two-head power supply; 4 Two heads 1/6 power supply;
Plastic are material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.
Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their actual name derives from this specific ability.
Rubber Plastic Products are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, however, an array of variants are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.
