How to solve the problem of low efficiency of concrete mixer.

　　1.粘物法：如果滾筒、托輥的局部上粘有物料，將使該處的直徑增大，導(dǎo)致該處的膠帶拉力增加，從而產(chǎn)生跑偏。應(yīng)及時清理粘附的物料。

　　If there is an increase in the diameter of the belt on the roller, it will increase the diameter of the roller. The adhered materials should be cleaned up in time.

　　2.混凝土的任務(wù)量及其工期的考慮：以此來選用多大規(guī)格的混凝土攪拌機，同時要考慮混凝土的瞬時和平均量。

　　2. The task quantity and construction period of concrete: how large the concrete mixer should be selected, and the instantaneous and average quantity of concrete should be considered at the same time.

　　3.除日常對商品混凝土攪拌機維護保養(yǎng)外，當(dāng)混凝土攪拌機運行一個月(二班制)后，要以操作者為主，維修工人配合，在規(guī)定的保養(yǎng)時間內(nèi)，按混凝土攪拌機機型規(guī)定的保養(yǎng)內(nèi)容及要求．對混凝土攪拌機進行一次一級保養(yǎng)。一級保養(yǎng)主要范圍是。

　　3.

Within the specified maintenance time, according to the maintenance contents and requirements of the concrete mixer model, the concrete mixer shall be maintained one level at a time. The main scope of primary maintenance is.

　　4.電源電壓升降幅度不超過額定值的5％。
