Traveling Block

Description: A Swivel is a mechanical device used on a drilling rig that hangs directly under the traveling block and directly above the kelly drive, that provides the ability for the kelly (and subsequently the drill string) to rotate while allowing the traveling block to remain in a stationary rotational position (yet allow vertical movement up and down the derrick) while simultaneously allowing the introduction of drilling fluid into the drill string. Parts: bail, Gooseneck, upper shell, body, lower shell, swivel stem, shaft, sealing system etc. Pictures:

1. Brief description CD1 electric hoist has only normal speed, which can satisfy the general working requirement. MD1 electric hoist has one more hoisting motor and one slow speed actuating device, which make the model have two speeds. When it works slowly, it can satisfy the precise task such as precise working of loading and unloading, sand to break-in. 2. Applications It can travel rotation through the trolley hanging on the I-steel, and install on the single beam crane, gantry crane, jib crane and overhang crane to rise and fall the cargos. So it can be used in factories, mines, wharf, warehouse, freight yards, and shops and so on which need lifting equipment for lifting heavy objects. Such as mining companies and railways, docks, warehouses. It is prohibited to manned. 3. Components Motor: Hoist Motor is an taper type rotor motor with braking,it is made by Nanjing special motor factory,it is of the best quality motors, it has bigger torque, so it can be adapted to moving frequently. Trolley: It is assembled and has running wheels. Herein, the runner wheels are mounted on top-class sealed ball bearings. Gear Box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings , to ensure smooth, low-friction operation. Wire Rope: Hoisting rope comply with the exporting ISO standards. The leading rope taken by the Drum, does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six. Rope Drum: Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running. Electric control system: Model CD1 and MD1 is composed of the contactor box,controlling switch,cut-off limiter.the working voltage of controlling switch is 380V,36V or 24V(safety voltage). Rope Guide: Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition. Hook: The Hook Block is tested to 150 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting . Testing: All our Hoists are tested on 125 % thus assuring safe working load and is issued with a test certificate. If you need other type electric hoist, please tell us, we will be pleased to be of further assistance!

Scope FDQ-0301 laser particle size analyzer based on physics Fraunhofer diffraction and Mie scattering theory basis. This theory can be simply understood as: travels in straight lines parallel laser beam blocking particles encountered in the communication process, the phenomenon of diffraction and scattering, and small angle light scattering large particles, small particles of light scattering angle is large. Figure 1-1 shows the diffraction pattern formed by individual particles, the larger the particle diameter, the smaller the center of the bright ring, the smaller the particle diameter, the larger the center of the bright ring. Use photo detector array receiving light at different angles, for the corresponding angle, its energy is set corresponding to the diameter of the particles occurs diffraction (scattering) caused by the respective other angle light will reflect the strength of the corresponding diameter of the particles throughout the assembly of particles occupies proportion, according to the intensity of the received scattered light at different angles, you can perform anti-particle distribution of the sample between the relative content and various size fractions. Features 1. Up to 82 sampling channels to improve the resolution of the test results; all the photovoltaic device fabricated on a single silicon chip, to ensure the life of the photovoltaic array; cross-sector arrangement, increasing the light receiving area, improves the sensitivity ; 2. micro injection method, using a peristaltic pump automatic loop injection mode, using siphon pump automatic cycle injection mode, to meet different customer test requirements, the instrument comes standard MS-01 micro-injector device; 3. The single lens full scale measurements, all optical components are mounted on reinforced base before fastening a good optical system is shipped, the instrument more stable performance; 4. Imported semiconductor lasers, has a long life, stable optical parameters, not afraid of vibration and a series of advantages, continuous working time of up to 24 hours, to meet user requirements for large continuous load test. Technical Parameters 1, the test range (um): 0.15-400; (0.4-1100,0.1-450,0.25-650, 0.4-1100) 2. Repeatability:
