Usage of New hydraulic system  Coal Mining Excavator:

Mining excavator is mainly used in underground mine, particularly for transporting excavated rock. It can also be used for the construction of railway, highways, water conservancy

and other tunnel projects. It is particularly suitable for poor working conditions, narrow operating site, low and muddy operating surface.


This machine employs DEUTZ air-cooled low-pollution engine which is advanced in today’s world and is deployed with dry-type platinum exhaust cleaner and silencer provided

by ECS.


Its transmission system uses hydraulic torque converter and power-shift transmission provided by DANA and thus it boasts light, convenient control, and smooth operation. The

vehicle’s hydraulic system mainly adopts the components provided by parker. The well-designed main frame structure ensures ruggedness and high efficiency.


Braking system uses full-hydraulic two-line mechanism, and comes equipped with fully enclosed multiple wet discs brake and ON-SPIN limited-slip differential for safe and

reliable operation in poor environments with high moisture content or on muddy roadways. It is designed with full hydraulic steering and manual control.


The new hydraulic system can accurately realize driver’s operation intention and can realize


stable feeling and powerful digging force which drivers longing for, the biggest characteristic is


non-hydraulic interference.

It will not be affected by loading even if it is operated over two work devices at the same time.

It will allocate all pump delivery to all of work devices to make the relative speeds of work

devices keep unchangeable and make controlling performance and operation improved

as per operating quantity of all of operating levers.

Moreover, the installation of other accessories is also very convenient.

Q:How to install the vibrating motor (a vibrating motor) in the vibrating screen? Parallel angle?
In addition there is a linear vibration motor vibration sieve is advanced, which is different from the ordinary vibration motor vibration motor, is a plate type vibration motor, the vibrating motor is arranged on the side of a shaker, which not only simplifies the structure of the machine and reduce the weight of the equipment, and improves the performance and technical parameters of screen, screen the relatively small volume, convenient maintenance, easy to process layout.
Q:What is a vibrating screen? For what purpose?
They generally have high efficiency, light quality, full range of diverse, multi-level, to meet the demand for dry material screening and other characteristics, so they are widely used in mining, coal, metallurgy, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries.
Q:What does the model of linear vibrating screen mean?
The running track of the linear vibrating screen is straight, and the YK series vibrating screen is a circular vibrating screen, and the running track is straight
Q:Why is the amplitude of ultrasonic vibrating screen smaller?
Specific solutions are as follows:1, screen problem: can use hand to check the screen is taut, plastic, found no tension or glue should be removed from the new stretch mesh screen.2 resonance problems: check the motor or screen frame, if found cracks should stop immediately, contact manufacturers for repairs.3, connection cable problem: can check the cable and plug insulation value, find problems solved in a timely manner.4 transducer problem: you can carefully check the grid and transducer contact parts, such as foreign bodies can be found thoroughly cleaned.
Q:How about paint vibrating screen?
Each kind of machine has its own characteristic and the good work domain, the vibration sieve is precisely such.
Q:What is the principle of the shock absorption system of a vibrating screen?
Working principleThis type of sieving machine adopts double vibration motor self synchronization technology. The two vibrating motors are respectively arranged at the top of the screen machine to rotate at opposite high speed, and the eccentric centrifugal force generated by the eccentric block of the rotating box causes the sieve box to produce a certain amplitude of linear movement. Because of the vibration sieve surface and the level of 10 degree angle installation, vibration line and the horizontal plane is 45 degrees, the screen material is passed to the sieve box and impulse continuous casting movement and the material is layered in advance, throw up, make less than sieve particles and slurry water through the sieve in and the screen met in the process of completing the screening process.
Q:What is vibrating screen?
Vibrating screen meshPosition, ensure that the mesh size, mesh has a two-way bending vibration ripple, locked bending, two-way separated wave bending, flat bending, unidirectional corrugated bending, solid structure, used for mine, mine, construction, petroleum, glass factory, metal products industry, a special pig net crimped wire mesh.
Q:Circuit principle and connection method of Derek vibrating screen
There is a whole sieve road or several road should not work, treatment is measured with a multimeter and the power line road, the resistance between the controlled silicon anode, a normal whole sieve or several road, work is less than 1, if the circuit fails, should check the fuse, current meter, electric magnetic coil, to see whether it is in the open state, and then check the SCR control cabinet to the output line of the electromagnetic coil is open circuit, control cabinet adjusting potentiometer, whether open or at least state,
Q:Why does the vibration screen run dust appear, how should solve?
On the other hand, not the device itself produces dust, but in a moment and feeding material caused by dust, if it is artificial feeding, to avoid dust, can in the above equipment plus closed silo and inlet sealing connection, the discharge port and the material receiving barrel sealing soft connection, the other can be added in dust collector the equipment to avoid dust.
Q:Why do you say that Xinxiang is the hometown of vibrating screens?
Xinxiang vibrating screen manufacturers accounted for about 70% of the total amount of the country.
