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 choose the vibration motor correctly
How to choose a suitable vibration motor, the main reference to the following two aspects:1, according to the production requirements and vibration sieve categories, first determine the required motor vibration times n (r/min) and double amplitude S (mm).1) six stage vibrating motor (n=980r/min), (S=8-12mm) suitable for multilayer vibrating screen, circular vibrating screen, long distance conveyor.2) four stage vibrating motor (n=1460r/min), (S=4-8mm) suitable for light linear screening machine, rotary vibrating screen, feeder.3) two stage vibrating motor (n=2870r/min), (S=2-4mm) suitable for high frequency vibrating screen, vibrating table and silo block.
Q:What is vibrating screen?
The method of changing the mesh1, put the ring screw or, remove the frame, the damaged mesh removed, replaced with a new mesh.2, the mother of online mesh tile in the vibrating screen, put the box back again, around the hands of mesh tension, in the fuselage on the edge frame and the lower frame edge ends, each with a universal clamp, the upper frame and the lower frame clamp.3, to highlight the edge of the box around the mesh in addition to set aside two centimeters apart shaker, cut off all the rest.4, ring again, loosen the ring beam universal pliers, screw hook lock.5, with a soft hammer knock around uniform beam, then the copper nut. The change of mesh is completed. If the mother frame and moving board are removed during the change of the screen of the vibrating screen, it must be noted that the moving plate must be inserted into the flange of the bottom of the grid.
Q:What measures are taken against the vibrating screen to avoid resonance?
The upper rotating heavy hammer of the vibrator causes the screen surface to produce a plane whirling vibration, while the lower rotating heavy hammer causes the screen surface to have a conical rotary vibration, and the combined action of the rotating heavy hammer causes the screen surface to generate a complex rotary vibration. The vibration trajectory is a complex space curve.
Q:What's the difference between a roller screen and a vibrating screen?
The vibrating screen is used to vibrate the vibrating motor to make the material pass through the screen.
Q:Difference between tailings dewatering screen and vibrating screen
Vibration sieve using vibration motor as vibration source, the materials is thrown up on the screen, at the same time for linear motion, the material feeding from the feeder evenly into the screen, screen material, produced a number of specifications through multi-layer screen material, from their respective outlet discharge. Low energy consumption, high yield, simple structure, easy maintenance, full closed structure, no dust, automatic nesting, more suitable for pipeline operation.
Q:Vibration sieve front and rear amplitude is not the same, how to adjust?
The weight of the eccentric block: increase the weight of the eccentric block (side eccentric weight) can increase the amplitude of the vibration sieve, the eccentric vibrating screen under the control of amplitude on the eccentric block vibration control screen about amplitude; can use according to their own situation to increase or reduce the weight of the eccentric block.
Q:What does the model of linear vibrating screen mean?
Zsf520 linear vibrating screen, as you say, means that "Z" means straight line motion, "SF" refers to the screen, and "520" is the dimension of the linear screen: 500x2000 (mm)
Q:What parts of a vibrating screen are expendable?
1, sealing strip plays a dustproof, sealing role, the work environment of workers, as well as the output of screening materials have an impact;2, screen filter materials accessories, need to check regularly to see if there are loopholes or damaged, to a certain extent will affect the material screening out the fine degree;3, bouncing ball in the screening of materials, do not block the screen, increase efficiency, to a certain extent will be smaller and smaller, timely inspection, prevent bouncing ball fall into the material.
Q:I have a vibration screen, with NJ428EM bearings, bearings can not be used for a week, the shelf is broken. Change a few sets, this is the case, what is the reason?
Such bearings allow the inner ring axis and outer ring axis angle error is very small, only 2 '-4'. Therefore, the machining accuracy of shafts and bearing housings is relatively high. Otherwise, it is easy to appear uneven contact and stress concentration in raceway contact parts.
Q:What is the vibration of the shaker?
The center of gravity of the vibrating screen is not on the exciting force line, causing the sieve body to swing. In the design, it is necessary to find the center of gravity of the screen, so that the force line through the center of gravity will do. The sieve is ready to swing and can be adjusted with a counterweight.
