Detailed Account of Hydraulic Jaw Breaker

PE Jaw crusher has many features, such as crushing cavity is deep and there is no dead area, which improves feeding capacity and output, Energy-saving: single machine can save energy by 15% to 30%; the system can save energy by over 30% to 60%; Simple structure, convenient maintenance and use; stable performance, low operation cost; high reduction ratio and so on, it is widely used in mining, building materials, chemical industry, and metallurgy and so on.
During the working process of the jaw crusher, the rotary of cam gear drives the plunger type injection pump to supply high pressure oil to the system. The oil pressure of the system will be determined by the rating nut of the oil pressure adjusting gear according the biggest crushing force allowed for the crusher. When the oil pressure goes up, the plunger compression spring in the oil pressure adjusting gear will shift to the right side, and drive the plunger injection pump plunger to rotate in the anti-clockwise direction, shorten the effective path of the plunger in order to decrease the oil injection amount and restrict the system oil pressure to go higher. On the contrary, when the system oil pressure decreases, increase the oil injection amount in order to prevent the decrease of the system oil pressure so that the oil pressure of the hydraulic system is kept in the original set state.
When the crusher is working normally, the pressure functioned on the working cylinder by the toggle plate of the crusher is smaller than the thrust of the hydraulic cylinder, and the movement calve is in an upper extreme position, and the toggle plate will not move so that the crusher will crush materials normally. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like impact breaker, Henan Hongxing is always doing the best in products and service.ceramic sand kiln: http://www.crusher-machine.com/n232.html
If some uncrushable materials go into the crushing chamber of the jaw crusher, the crushing force will increase. At this time, the pressure functioned on the working cylinder by the toggle plate of the crusher will be higher than the thrust provided by the hydraulic cylinder, and the oil pressure in the high pressure oil chamber will increase in a second, the throttle valve will drive the movement valve to move, and the system will leak oil in order to limit the biggest thrust of the toggle plate in order to protect the machine.
With domestic infrastructure and the continued development of the national economy, China’s construction machinery market has become the focus of attention of the international equipment manufacturers, crushing machinery industry is no exception, and the entry of foreign capital, further exacerbating the degree of competition in the market, the domestic crushing machinery enterprises in order to tide of competition opportunities,rock crusher the primary problem is to improve the quality of the existing crushing equipment and technical content, to narrow advanced level abroad, to create their own brand to gain market initiative, broken by comparing the domestic and foreign the mechanical gap to mechanical status quo broken at home and abroad.
