Bucket digging pilot circuit.\u003cbr\u003e2. Auto accel operation.\u003cbr\u003e3. Constant control of standby flow rate.\u003cbr\u003e4. Bucket digging main circuit.\u003cbr\u003e1. BUCKET DIGGING PILOT CIRCUIT\u003cbr\u003eMechatronics:\u003cbr\u003e1. When the operation for bucket digging is performed, the pilot proportional secondary pressure is delivered through port 1 of the right pilot valve (10), flows to PBc port of the control valve (2), and acts on the low pressure sensor (SE-1), and at the same time the bucket spool is switched.\u003cbr\u003e2. The voltage output by the low pressure sensor (SE-1) sent to the mechatro controller and is signal processed, and then the mechatro controller outputs the command current to increase the pump flow rate to solenoid proportional valve (PSV-P1) on the P1 pump side. P1 pump proportional valve increases the flow rate by the pump positive control operation.
