The Common Breakdown and Maintenance of Jaw crusher

Jaw crusher or vibration in the process of running under torque is bigger, often triggered by heavy system liability. They are commonly: the pulley and shaft head a gap caused by the axis head and the wheel wear and force of eccentric shaft bearing wear and so on.

Appear afore-mentioned problems after the traditional repair method is to wheel hub bore hole, machine repair, after repair welding or brush plating, but both has certain disadvantages: repair fusing high temperature current stress can not wholly remove, easy cause physical damage, lead to curve or disruption parts. And encounter electroplating coating breadth restrictions, informal to peel, and two approaches above are with metallic repair of metal, can't change "hard to hard" collaboration relationship, under the force mixture, still can cause wear again.

The maintenance of jaw crusher methods are not common in western countries, modern Europe and the United States and other developed countries in view of the above problems of use of polymer composite materials to repair method. Application of a country is the most mature technology, and it has strong adhesion, excellent comprehensive properties such as compressive strength. Free machining is removed for field repair. Maintenance has neither repair fusing current stress with polymer material, repairing the thickness is not restricted. And the produce of metal resources does not have rolled back, which can engross the impact of shaky equipment, avoid wear and tear, and importantly extend the facility life of equipment components. And initiatives save numerous stoppage, thus creating huge financial worth.

The lubrication has 3 aspects that need to notice:

(1) Attention on and often makes resistance surface lubrication work, timely to ensure the usual process of the machine and prolong its service life. (2) The jaw crusher oil should be putative rendering to the use of site, temperature circumstances, typically uses the calcium base sodium, sodium and calcium base oil. (3) Adding grease the bearing seat of its space about 50% of the volume, replace a piece every 3 ~ 6 months. Application in an oil change clean petrol or kerosene cleaning roller bearing raceway. (4) The jaw crusher before moving between thrust plate and thrust plate bearing should be vaccinated into the correct amount of grease.

In order to promise the usual work of the jaw crusher, as well as the correct operation, planned preservation must be conducted, including everyday maintenance inspection, minor repairs, repair and overhaul. Minor repair mainly includes check and repair the change device, adjust the discharging mouth gap, lining panel of wear head or spare. Check the transmission part, lubrication system in a timely manner, and in lubricating oil and so on. The series of minor overhaul is 1 ~ 3 months of the time or so.
