As a system of industrial crushing and sand production line that is commonly used in a rough broken machine, the jaw crusher operation work, mainly based on motor power, eccentric shaft driven by a v belt and the sheave, the moving jaw according to the desired trajectory for reciprocating motion, thus will enter the fixed jaw, jaw and side guard plate of crushing cavity material to be broken, and through the lower part of the discharging mouth of the finished material.
The jaw crusher adopts advanced digital parts processing equipment, which makes the internal structure of the jaw crusher equipment more precise, and the deeper crushing chamber ensures higher production efficiency.
The following xianji network small part to introduce the jaw crusher eccentric shaft, connecting rod, bracket, moving jaw, tooth plate and other 6 parts of the installation points, dust cause analysis, how to avoid easy wear jaw plate?
The reasons for the clogging of the discharge port, the reasons for the rupture of the bracket and the countermeasures, the problems and solutions of the flywheel, and how to deal with the shutdown phenomenon in the process of operation?
1.Installation of broken jaw frame
In the installation of the crusher frame should be placed between the frame and concrete on something that can absorb vibration, such as: hardwood, rubber, etc., the installation of the frame on the foundation or in the wood base of the transverse and longitudinal levelness should meet the installation requirements of the equipment.
When mounting the frame, the horizontal and longitudinal levelness of the frame placed on the foundation should be less than 0.2mm.
2.Assembly key points of eccentric shaft and bearing broken jaw
Before the shaft and bearing assembly, need sliding bearing will do a good job and then put it in the sliding bearing seat, by using the level of its place levelness and coaxial degree for testing, if the measurement results meet the requirements, the eccentric shaft is installed on the bearing, again through the daub on the shaft neck red lead powder to see cooperation between shaft and bearing.
If the surface height of the sliding bearing is too high, further scraping should be carried out until the height between the contact surfaces disappears. Finally, apply a certain amount of lubricating oil between the bearing seat and the bearing to reduce the wear of the shaft. The contact area between the sliding of the eccentric shaft and the frame should be no less than 80%, and the clearance should be less than 0.08mm.
3.Installation of broken connecting rod
After the above parts are installed in place, the connecting rod can be installed. Before the connecting rod assembly, the connecting rod and the required assembly position should be carefully checked. After there is no problem, lift the connecting rod with a crane, and clean the whole connecting rod with gasoline or kerosene.
Then on bearings, shaft, bearing and connecting rod on the shell, and then lift the connecting rod, the connecting rod with the connecting rod bolt and screw down the, such as between shell on the connecting rod and connecting rod with liner, which cooperate closely not cause leakage, deal with liner for processing or install a new gasket, if conditions allow, can through the outside connecting rod and main shaft parts assembled in driving to integral into frame after use.
4. Installation points of jaw broken floor plate
The floor plate with broken jaw can be installed and removed by loosening the spring nut of the pull rod, then the lower part of the moving jaw can be tied with a chain or a wire rope, and then the driving wire rope can be used to make the moving jaw close to the fixed jaw, and then the floor plate will fall off automatically. Only the above steps can be repeated in reverse during installation.
5. Key points for installation of broken jaw
Firstly, the movable jaw parts shall be assembled accordingly. On the ground, the movable jaw parts, movable jaw shaft, movable tooth plate, floor pad and other parts shall be assembled together in the frame of the crusher by crane or crane.
For sliding bearing, it is necessary to grind and match the bearing and bearing seat first, so as to install the sliding bearing in place. At the same time, the coaxiality and inclination of the assembly of the sliding bearing are tested. The inclination is ensured at 0.2mm and the coaxiality is less than 0.06mm, so as to complete the assembly of the moving jaw.
6.Key points of installation of jaw broken tooth plate
Jaw crusher tooth plate is directly used for crushing ore parts, its structure is simple, but because often contact with the ore, often need to be replaced, tooth plate cross section structure shape has smooth surface and lattice surface two kinds, because of its weight is larger, need to make easy to replace the structure.
The tooth plate is fixed with bolt or wedge, which is fixed on the front wall of the frame or on the movable jaw, and the contact surface between them must be straight. If there is a high contact point, it needs to be processed in time.
Since the inner side of the front wall of the frame is not machined, a layer of soft metal gasket is put between the back of the fixed jaw plate and the front wall of the frame to ensure the tightness of its combination.
Whether the installation and assembly of jaw crusher are in place or not largely determines the performance of the equipment, so the correct installation and operation is very important.
