S003-0102 sprocket assembly plays an extremely important role in the whole scraper conveyer. Its performance directly affects the production efficiency, product quality and service life of the scraper conveyer.

S003-0102 sprocket assembly is mainly composed of bearing cover, bearing housing, roller, sprocket, shaft, floating seal, roller bearing and so on. Power output by the reducer, through the sprocket shaft to the sprocket spline, so that the sprocket drive scraper operation. The s003-0102 sprocket assembly is lubricated by thin oil, sealed by mechanical float, and lubricated by long distance. The s003-0102 sprocket assembly can be disassembled as a whole for easy maintenance without disassembling the transmission.

7S003-0102 sprocket components in the installation and use of daily maintenance, take preventive measures in advance, to extend the service life. If you need sprocket assembly, you are welcome to contact us in time.

The 7S001-35 hydraulic chain reducer is installed on the connecting casing between the main engine reducer and the motor, and the hydraulic motor drives the main engine reducer to achieve the purpose of tensioning the scraper chain.

7S001-35 hydraulic chain tensioning device is a kind of scraper chain tensioning device powered by hydraulic motor, which is composed of transmission box and hydraulic control system. The hydraulic control system includes control valves, filtration devices and piping, etc. Attention should be paid to the installation of 7S001-35 hydraulic chain fastener:

1. Before each tightening chain, the main engine motor cannot be powered on when the chain reducer meshing with the main engine reducer.

2. The hydraulic motor cannot be used as power transport material, otherwise it may cause premature damage to the hydraulic motor.

3. In the process of tightening chain, the materials on the main machine should be cleaned as far as possible.

4. Pay attention to the observation when tightening the chain, should understand that the scraper chain tension is increasing, remember not to make the chain too tight.

The 7S001-35 hydraulic chain fastener belongs to the main engine accessories of Zheng Coal machine. When in use, please pay attention to cut off the power supply of the main engine motor and fix the scraper chain with the chain stopper.

scraper conveyor, incline Scraper Conveyor, underground conveyor systems
Introduction of SGD-280/11 Underground Incline Scraper Chain Conveyor
SGD-280/11 Underground Incline Scraper Chain Conveyor applies to slow gently inclined thin coal seam working face conveyor of coal. Mining height is broken floor to 0.6 m, dip Angle of coal seam is not more than 25 degrees. SGD-280/11 Underground Incline Scraper Chain Conveyor is more suitable for hard coal, large blocks or more inner dirt band conveyor coal.
Main Characteristics of SGD-280/11 Underground Incline Scraper Chain Conveyor
SGD-280/11 Underground Incline Scraper Chain Conveyor has simple structure. It not only can convey in the level and vertical transmission, but also can be combi ned in layout, cascades transmission, does more feeding and multi-point discharge. It is more flexible in art processing. Because the shell is closed in the transportation of materials, so it can be significantly improved to prevent environmental pollution.

Henan Shuangzhi machinery as henan scraping machine accessories manufacturers, especially scraping machine accessories business is quite perfect, product variety, a relatively complete, the host has zhangjiakou manufacturer, shandong, shanxi coal, mining machine, the bull run of huainan longwall, linzhou heavy industry, etc., product categories such as scraping board, e type bolt, u bolt, beams, the sprocket shaft group, dumbbell pin, card block, guard board, dial the stopper, coupling and brake disk connected sets, central trough, chain tensioner, even pick up board, lap board, elastic plate, rack, rack pin, passes, headstock, tail carriage and so on. Scratcher accessories we Henan Shuangzhi do is relatively complete, but also to meet the needs of market customers Scratcher accessories, because of focus, so the quality is guaranteed.



Henan scraping machine accessories manufacturers double of henan machinery in order to develop and market needs, product business is expanding, hydraulic support accessories, crusher accessories, move the tail accessories also have involved, as manufacturing, technology and equipment is our bottom spirit and strength, the customer need, we can do, support to sample processing, drawing processing, cooperative diversity, just to give customers a better service!

The chain tensioner of the scraper or the chain tensioner of the transfer machine is divided into manual chain fastener and hydraulic chain fastener. By applying certain pre-tightening force to the chain of the scraper, the scraper conveyor can operate safely. When tightening the chain, fix one end of the chain scraper on the side plate of the nose frame or chain chute, and bypass the other end of the chain wheel of the head to make the chain wheel reverse, and then the chain scraper is strained. When the chain tension of the chain scraper is appropriate, the chain scraper will brake to prevent the chain of the chain scraper back loose. After the two chain heads are connected, the chain scraper will remove the brake.

The working principle of the chain tensioner is very simple to look at and easy to operate. It is also the spare parts of the scraper that can be purchased in the daily life of coal mine. Henan Shuangzhi Machinery focuses on the production and processing of scraper conveyor parts, more scraper parts welcome to pay attention to us!

The hydraulic chain controller is composed of two parts: the gearbox and the hydraulic control system. It is installed on the connecting cover barrel between the main engine reducer and the motor.

When adjusting the hydraulic control valve set during installation, please note:

1. Carefully observe the pressure gauge when adjusting the hydraulic control valve group. As soon as the pressure gauge is out of range, cut off the pressure source quickly to prevent damage to the gauge.

2. The adjustment should be patient and meticulous, and the recommended amount of each adjustment should not exceed 0.5mpa.

3. The hydraulic control valve set should be handled with care to prevent knocking and scratching the anti-rust layer.

4. After adjustment, lock the handle of the pressure reducing valve.
