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.
Picture of New hydraulic system Coal Mining Excavator:
- Q:Mounting angle of vibrating screen
- Different types of vibrating screen installation angle is different, such as vibration screen installation angle of more than 30 degrees, general purpose vibration sieve angle of 0-15 degrees, while the sieve used for dewatering is the end of the upward tilt
- Q:How to solve the screen block of vibrating screen?
- There are many factors affecting the screening rate of materials, but there are two main types of materials. One is the various characteristics of the material itself, and the other is the vibrating screen structure of the two.
- Q:General ultrasonic vibration sieve for the purpose of how many nets, 100 of the target material does not add ultrasonic influence?
- The ultrasonic vibration sieve mainly aims at the screening of ultra fine powder materials and some materials with adsorption, sticky net, electrostatic and light weight
- Q:Can the 37KW frequency converter start the 30KW vibrating screen motor?
- Yes, but pay attention to modify the motor parameters of the inverter, for example, motor power, motor current, etc., you need to see the frequency converter manual
- Q:A formula for calculating the natural frequencies of vibrating screens
- Calculation method of processing capacity:Q = 3600*b*v*h* gammaWhere Q: processing capacity, unit t/hB: screen machine width, unit MH: average material thickness, unit MGamma: material stack density, unit T / m3V: material running speed, unit M / S2. The calculation method of material running speed of linear vibrating screen is:V=kv* lambda * Omega *cos (delta) * [1+tg (delta) *tg (alpha)]3. The calculation method of material running speed of circular vibrating screen is:V=kv* lambda * Omega 2* (1+) * *Among them, kV: comprehensive experience coefficient, generally take 0.75 ~ 0.95Lambda: single amplitude, unit mmOmega: vibration frequency, unit rad / SDelta: vibration direction angle, unit degreeScreen angle per unit angle4, dynamic load: P=k* lambdaWhere K: composite spring stiffness, unit N / MLambda: amplitude, unit MP: dynamic load, unit NThe maximum dynamic load (resonant dynamic load) is calculated 4~7 times as much as the above mentioned result
- Q:How to adjust the vibration frequency of vibrating screen?
- Open the end cover of one end of the vibrating motor on the vibrating screenYou'll find a cam inside, with scales on itAdjust the cam number to achieve the magnitude of the frequency
- Q:The vibration of the motor seat of the vibrating screen is cracked when it is used. It is He Yuanyin
- In the process we use vibrating screen, there will inevitably be wrong, if the use is not standard, the normal operation of the vibrating sieve will bring inconvenience to the base damage permanent machinery vibration motor analysis
- Q:How to adjust the angle of the weight of the vibrating screen?
- The upper and the lower ends of the vibrating screen are respectively provided with an eccentric heavy hammer, the upper eccentric block is a fixed block, and the lower eccentric block is an adjustable block which is locked on the motor rotating shaft by using a fastening bolt.
- Q:How do I seal the shaker?
- Vibration sealing strips, seals, sealing rings, vibrating screens, bucket elevator and large inclination belt conveyor can be used
- Q:Design points of vibrating screen
- Selection of width and length of screen surfaceThe length and width of the screen is a very important process parameters of screen. Generally speaking, the surface of the screen width determines the processing capacity of the screen, the screen surface length determines the screening efficiency and screen so that the correct choice of the length and width of the screen, it is important to improve the production capacity and efficiency of the screen the extension.The width of the screen surface is not only affected by screen processing ability, is also affected by the screen structure strength. The greater the width will increase the screen size, the more problems need to be solved on the structural strength of screen is more difficult, so the surface of the screen width cannot be arbitrarily increased. The maximum width of the vibrating screen in China is 3.6m; the maximum width of resonance screen for 4m.
