check the the admixture impeller situation, as the case of replacement parts. Belt damage. Failure phenomenon: use one end of the time, the belt electric trailer pumps surface degumming, cracking, scratches and other phenomena. Analysis: metal belt cleaning if not timely adjust, easy to damage the belt, causing the belt surface rubber off. The sweeper is not installed correctly, the sharp gravel cards will damage the belt between the sweeper. The poor quality of the belt itself, are also prone to the above-mentioned defects. Process: Once the belt degumming, cracking, scratches and other defects should be promptly repaired. When the belt injury, we must first solve the factors causing belt damage, such as damage to the sweeper, you need to immediately adjust or replace the sweeper, then promptly repair the belt. Belt damage is very small, can belt repair glue-site repair. When and belt damage surfaces or severe local damage to local damage belt cut away, the replacement period of belt vulcanizing machine cementation. Belt injury is not promptly treated, the damage spread to the entire belt, no repair value, only the entire replacement. Belt conveyor aggregate uneven. Failure phenomenon: aggregate unloaded onto the belt material accumulation, resulting in the bulk material belt or belt conveyor aggregate vacancies caused pebbles scattered material. Analysis: ingredients the station variety of aggregate unloading belt sequence and time interval can be arbitrarily adjusted at any time. General discharge order requires the last unloading the aggregate for the the sand unloading time interval required for the former hopper lift concrete plant for sale aggregate falls on the belt tail just coincidence fell on the belt on the head with the latter aggregate. Such as the time interval is too short, then the former aggregates with the latter aggregate overlapping Stockyard Stockyard too much will cause the bulk material, such as the time interval is too large, then the two aggregate there is portable concrete batching plants space in the middle, the former If the material is gravel, is wallowing in the belt and fall down. Treatment process: Adjust aggregate discharge order, ensure the sand for the last discharge. 2, according to the distribution of the aggregate in the belt to adjust a variety of aggregate time for unloading interval to ensure that belt material on the continuous, uniform distribution. The interval normally takes several adjustments. Concrete mixing plant troubleshooting method nine, can not adjust the pressure relief valve pressure gas source FRL. Failure phenomenon: rotation reducing valve hand wheel adjustment, but the pressure can not be adjusted. Analysis: 1, pressure reducing valve import and export orientation install anti. 2 sliding parts embedded foreign body or spool, spool of a foreign body stuck. 3, the regulator spring, the return spring, the diaphragm, the spool on the ready mix concrete plants supplier rubber pad damage. Process: 1, check the pressure relief valve import and export for the correct orientation. 2, break up the check valve core and related parts and clean up debris on parts. 3 parts damaged, replace the pressure relief valve. Gas source FRL lubricator drop of oil or drip volume is too small. Failure phenomenon: the flow of compressed air, but lubricator drop of oil or a drop of oil is small. Analysis: 1, the direction of the import and export of oil mist install anti. 2, the oil duct blockage.
