After the commercial concrete mixing station is completed, it must meet the acceptance standards.Vertical mixer图片Only in safe production。So, what is the installation and acceptance standard of commercial concrete mixing station, and what requirements do the equipment of mixing station meet to meet the inspection standard。Chongqing Shiqiao Dinggu Construction Machinery Co., LTD., a simple to explain to you: 1.Commercial concrete mixing station mobile mixer，It should be installed on a flat and hard floor，Secure with wooden squares or braces，And maintain level，Do not use tires instead of support，If the use time is longer (generally more than 3 months), the tire should be removed for safekeeping，The end of the axle should be cleaned and rust-proof。2.The fixed mixer of the commercial concrete mixing station should be installed on a firm pedestal. If it is used for a long time, the anchor bolts should be buried. If it is used for a short time, the wooden pillows should be laid under the machine and levelled。3.For the mixer in the main machine of the commercial concrete mixing station, the leakage protector parameter of "one machine, one gate, one leak, one box" should be set to 30M A×0.1S, the motor insulation resistance value should be greater than 0.5MΩ;Protect the neutral line at least two places, the instrument and indicator signal of the operating station are accurate and reliable。4.The transmission mechanism, working device, clutch and brake of commercial concrete mixing station should be fastened, flexible and reliable, and the protective cover is complete。5.For the concrete mixer that needs to be dug with a hopper pit, the pit mouth should be tamped with a cushion height, and the bottom end face of the loading track frame should also be tamped or the back of the bricklaying frame should be supported by wood to prevent long working time and track deformation。6.The steel wire rope used in the commercial concrete mixing station shall not be scrapped, such as rust, broken wire, flattening, etc。7.The safety hook on the body of the commercial concrete mixing station, the hopper upper lifting ear should be intact, when the hopper rises,专业Vertical mixer图片Safety hooks should be attached。8.The concrete mixer should be equipped with an awning, no mud around the machinery, clean and tidy, and all kinds of signs are complete。

Concrete mixing station can not be immediately left after work 1.专业Vertical mixer图片After the work is completed, the residual water and additive in the pump, additive pump, water tank, additive tank, water and additive pipeline should be drained to prevent damage to the pump and its pipeline, and start the additive pump of the pump to run for 1-2 minutes。2.Clear the ash accumulation inside and outside the wall of the mixing tank, the concrete residue on the discharge port, the mixing shaft and the discharge door, wash these centers with water, and if necessary, put in a small amount of stones and water to stir for a few minutes before releasing。Clean vehicle, additive tank and supply system with water。3.The smooth points are located in the discharge door shaft of the mixer, the door shaft of the storage hopper and the weighing hopper, the belt conveyor, the machine support wheel, the press wheel, the roller, the bearing, the transmission chain, the upper and lower end bearings of the spiral shaft and the main machine gear。4.专业Vertical mixer图片Check the wear condition of blades, scrapers, mixing arms, etc. Adjust the clearance or change it if necessary;Vibrator coupling bolt is loose or not;Check contactors in electrical appliances;Whether the static contact of the intermediate relay can be damaged and burned。

First of all, when choosing a concrete mixer, we must make it clear that choosing a good one does not just mean that the material is good and the price is expensive。As the saying goes, what suits you is the best, and the blender is no exception。1, the difference of mixer materials For the mixer of this type, model diversification of the machine, choose to suit their own is undoubtedly a big problem。Therefore, when choosing a blender, we must first confirm the difference between blender materials, some of which are dry powder专业Vertical mixer图片Some of them are liquidVertical mixer图片There are also solid-liquid mixtures, so as long as the difference between materials is determined, the scope of application can be reduced。2, the speed of the mixer is followed by the mixing speed of the mixer, the natural production efficiency of the fast mixing speed is high, and the slow mixing speed will naturally affect the progress of the construction。3, the difference between any mixer and its mixer accessories will have inaccessible corners, commonly known as dead corners, so choosing a small percentage of dead corners will greatly improve the production efficiency of its machine。

Operation and maintenance of concrete batching machine 1, before the shift should check whether the weighing device is in normal working condition, if there is a blockage affecting the weighing accuracy phenomenon should be eliminated in time。2、专业Vertical mixer图片Check whether the wiring of the electrical part is correct and firm, and whether the electrical box shell is firmly grounded。3, in the operation at any time to check whether the operation of each part is normal, the conveyor belt is deviated, there is no foreign matter between the belt and the driven roller, if there is an abnormal situation immediately stop and eliminate。4. Each active part should be filled with butter, and the belt roller should be removed and refueled once a year。5, in the maintenance of the machine, must stop and cut off the main power supply。6, the batching controller should have rainproof, sunscreen and dustproof facilities。7, prevent sand, stone mixed with steel bars, large stones and other debris, so as not to damage the conveyor belt。8, in order to ensure the safety of the batching controller, do not use in severe weather conditions such as wind and rain, thunder, and turn off the main power supply, remove the connection between the sensor and the batching controller, to prevent damage to the controller。9、四川专业Vertical mixerThe power supply voltage fluctuation must be less than -5 ~ 5%。10. At least every year, the weighing system should be calibrated according to the scale method in the instruction manual of the batching controller to ensure the accuracy of the weighing。
