HZS90 concrete batching and mixing plant operation rules
The operation rules for HZS90 concrete batching and mixing plant is as below.
(1) The production instructions issued by the station manager of the concrete batching plant or the project sales manager shall not be turned on.
(2) It is not allowed to stop production or stop production without authorization.
(3) Accurately input the mix ratio; carefully re-inspect all data entered, and the test personnel and operators can sign the record after confirmation.
(4) Produce strictly according to the mix ratio. Without the written instructions of the laboratory test personnel, no one is allowed to increase or decrease the raw materials, admixtures and water consumption. The mixing time depends on the state of the concrete and may not be increased or decreased at will without the consent of the test personnel.
(5) During production, it is necessary to closely observe whether the measurement is accurate. If the specified error is exceeded, the drop should be adjusted in time. All measurements should be in the range of small values at no load. Other abnormalities in the metering system must be reported and processed in a timely manner.
(6) The error of cement, admixture and water should not exceed 1%. When the quality of cement and admixture is not enough, it should be timely checked whether the auger is clogged and removed in time. The aggregate error can not exceed 2%. When the error exceeds the standard, the cause should be found in time. And manually compensate and record.
(7) When unloading, the discharge port and the tank feed inlet should be aligned, and the dumping material is missing.
(8) At the end of the operation, turn off the following switches: water pump power switch; main power switch; main control switch; additive pump switch;
Air compressor switch;
(9) Within two hours after the completion of the operation, all the concrete parts in contact with the concrete mixer should be cleaned, and the cumulative clean-up phenomenon is not allowed for a period of time.
(10) There is a power outage in the production of concrete, and the material is immediately unloaded and the relevant parts are cleaned.
(11) Strictly perform according to the instruction manual of the mobile concrete mixing plant.
(12) Before the official production start-up equipment, it must cooperate with the maintenance personnel. The length of one bell is not less than 10 seconds. After the maintenance personnel confirm that there is no accident obstacle in each mechanical working part, the call will be notified and the second bell will be played. It should be no less than 6 seconds. The device will operate after 6 seconds of stopping.
(13) According to the equipment manual and specification requirements, the calibration of various electronic weighing equipment of the concrete batching and mixing plant should be carried out regularly with standard weights, and then weighed in real quantity to see if the measurement error meets the requirements and records are made. The tester should be notified to calibrate at the same time.
