In shearer model: MG150 / 375 meaning: Mg means drum shearer, 150 means cutting motor power is 150KW, 375 means total installed power is 375kw< Sgz630 / 320 flexable scraper conveyor model: s-conveyor, g-scraper, z-medium double chain, 630 middle groove width 630mm, 320 installed power 320kw< Model of szd630 / 75 bridge type transfer machine: s-conveyor, Z-transfer machine, d-medium single chain, 630 middle slot width 630mm, 75 installed power 75kW.

3. Cutting motor 2x200kw, total installed power 500kW (oil pump 20kW, traction 2x40kw?), Q represents that the traction inverter is a four quadrant, which can realize electric energy feedback and ensure good large slope operation.

4. Are you from the mine upstairs
do you have 1140V DC in your mine? What is the DC power of your shearer
is your shearer DC or AC<

give a positive solution to the building owner

m-shearer
g-drum
450 - cutting power 2 * 450 (kw)
1020 - total installed power (cutting part 450 * 2, traction part 50 * 2, 20 are all kinds of auxiliary pumps)

d-electric traction

what else can I know~

drum shearer is a shearer which is equipped with a cutting cutter and rotates around the horizontal axis. When the drum shearer is working, the random body of the drum moves along the coal wall, the cutting tool cuts into the coal body under the action of the machine traction, and the coal is broken down from the media by using the torque generated by the drum rotation

The early drum shearer used drum drum as working mechanism, and the broken coal needed to be loaded into the working face conveyor with the help of special coal loading mechanism such as plough board

modern Drum Shearers all use spiral drum as the working mechanism. While the drum breaks the coal, it uses spiral blades to load the coal into the working face conveyor

{rrrrrrr}

extended data

there are two ways of coal cutting:

① one-way coal mining, the shearer moves upward to cut coal, and the coal is loaded downward. The advantage is that it can make full use of the machine to load coal with high efficiency, but it takes a long time to cut a knife in the working face and the roof hanging time is long. It is generally applicable to the coal seam with stable roof, large mining height and large amount of resial coal

(2) two way coal mining, one knife for each round trip. The advantages are that the utilization rate of working hours can be improved, the proction capacity of the working face is large, the roof is supported in time, and the working procere is compact, but the workload of cleaning floating coal is large when the mining height is large

double drum shearer: the full height is mined at one time, and there is one drum at each end of the shearer. The front drum cuts the top coal on the top and the rear drum cuts the bottom coal on the bottom. The two rollers generally rotate in opposite directions. The roller on the driver's left side uses the left screw, and the roller on the driver's right side uses the right screw

The roller on the driver's left side uses the right screw, and the roller on the driver's right side uses the left screw. Generally, it adopts the way of two-way coal mining and the advanced cutter moves the machine head backward; It can also adopt the tangent feed mode of moving the machine head at the same time

6. Taiyuan Heavy machinery, electric haulage shearer with total motor power of 1940KW.

7. Drum shearer single cutting power of 300 kW, total power of 720 kW, single traction power of 60, low row, chainless electric traction shearer

8. We use the pa28b receiver. Recently, the one on the left is not easy to use, and the effect on the right is very good
. What's the matter? Also, if I want to connect the receiver antenna from the back of the fuselage to the front, will it affect the reception effect?
