1, the diesel engine can not continue to start more than 5 seconds, can not be started more than three times, can not start three times should check the oil circuit, circuit. 2, the diesel engine does not start, can not preheat the asphalt pump. 3. The red light of the charging indicator light indicates that the engine is not charging the battery and the device is faulty. The circuit and the electrical appliance should be overhauled. 4. If the starting machine is slipping, adjust the starter bracket position. 5. During the process of clutch disengagement and engagement, pulling the clutch handle enables the clutch to be reliably and smoothly separated and combined, and no catch-slip phenomenon may occur. Adjusting the clearance between the clutch release lever and the release bearing can be achieved by adjusting the clutch cable pull cable. 6, Asphalt pump rotation has not been sprayed asphalt (1) Adjust the engine speed; (2) Check whether the asphalt pipeline is blocked; (3) There is air in the asphalt feed line, which allows the asphalt pump to run for 30 seconds and exhaust the air to spray it. Cold die forging, cold extrusion, cold upsetting and other plastic processing.Cold forging is the forming process under the re-crystallization temperature of materials.It is customary to refer to the forging of unheated blank as cold forging.Cold forging materials are mostly aluminum and some alloys, copper and some alloys, low carbon steel, medium carbon steel and low alloy structural steel with low deformation resistance and good plasticity at room temperature.Cold forging good surface quality, high dimensional precision, can replace some cutting processing.Cold forging can strengthen metal and improve the strength of parts.
