Symptom Cause Action 1, temperature table shows flashes, heat pumps and heat resistance line automatically start wrong, broken, damaged, check the line, replace the heat resistance 2, two pump flow switch setting is not appropriate, the line break line, filter dirty, clogged pipes, oil in bubbles, check the flow switch and wiring. Clean the filter, check the oil. Pump continuously circulating oil. 3, white light is not on the heated state, the pump does not start normally flow switch is not turned on, the light is damaged, the state does not start heating pump Check the flow settings. Replace the lamp. 4, the temperature table without electricity power phase meter is damaged or missing zero line fuse blows, there is a short circuit to check the power to replace the thermostat replacement table check cause of the short fuse 5, the PLC X4 on the roll crusher, X5 light does not appearance of the corresponding thermal relay auxiliary contact is open, the motor over-current, over-current thermal relay damage inspection reason to replace the thermal relay 6, the power light does not shine on the PLC power phase is damaged or missing PLC zero line fuse blows, there is a short circuit Check the power to replace the PLC to check the phenomenon cause of the short fuse replacement. waterfall falling into the material when the second feed size is larger than the expected size of the impeller to time, you need to feed from two feed ports respectively. Ore hopper into the river gravel crusher, respectively, through the sub-feeder feeding tube into the center of the impeller, when the materials into high-speed rotation of the impeller, the impeller being rapidly accelerated in the Sand manufacturers, up to several times its acceleration as well as several hundred times the acceleration of gravity, and then at a rate per 70-100m / s from the impeller projectile out, first with the free-fall into the whirl crushing cavity material impact outside the impeller and broken, and the impact of the eddy break together the top of the third generation of the bed chamber materials Sand, is sprint onto the bed material rebound oblique whirl crushing chamber, but also to change its direction of motion, deflected downward movement, emitted from the impeller material to form a continuous material curtain, so that a material in the turbine as well as the crushing cavity by two times the impact crushing effect. Throughout the crushing process, the material is self-reciprocal impact crusher, not in direct contact with the metal element. Because of the material from the impeller channel emitted oblique peripheral impact, forming materials in the crushing cavity eddy rotating motion on the bed material, the material between the moving vortex generator Sand ground effect, due to the impact of friction between materials The crushed material was broken discharged from the discharge port. Henan Senda Heavy Sand river gravel production with high performance stability, reasonable structure, high degree of automation, the entire production line in addition to equipment and routine maintenance of the boot down, the process is simple, almost no manual operation and other advantages, It is important to its high efficiency, low operating cost, high yield, high-yield, finished stones uniform size, grain shape is good, in line with the national high-speed material requirements. vsi crusher Features: 1, simple structure, low cost. 2, energy efficient, high crushing efficiency. 3, with a crushing, coarse grinding function. 4, through the strong ability of non-broken material, material moisture by a small impact, moisture content up to 8%. 5, can be broken in the hard, especially hard materials (such as corundum, sintered bauxite, etc.). 6, the product was a cube, a small iron contamination. The third generation of Sand, Sand Yueqing, Yuxin Senda provided by Henan new Senda Heavy Machinery Co., Ltd.. Henan new Senda Heavy Machinery Co., Ltd. (www.hnsdzg.com) strong, credible, in Zhengzhou crushing grinding equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Yuxin Senda and you hand into the brilliant, for a better future!
