Cementing trucks currently used in the cementing market are mainly model 45-21 and 40-17. These two types of cement trucks are the two most widely used cementing models, with reasonable vehicle design, mobility, Operational, easy maintenance and other advantages. However, with the expansion of the cementing external market, the training of operators has not been kept up to date, resulting in inconsistent operating skills and maintenance knowledge of the operators. In the course of use, some failures often occur, causing construction interruptions or influencing construction. quality. For some problems in cementing construction, Xiao Bian analyzed these typical faults and found out the countermeasures for reference. Typical fault phenomena and analysis processing. First, conducting a circuit inspection before the vehicle is out of the vehicle can largely prevent the failure of the cementing equipment to cause failure. Therefore, before starting the vehicle, the vehicle should be checked against the route of the vehicle inspection. Second, before the construction of the inspection After the vehicle has been driving long distances to reach the wellsite, be sure to check the vehicle before construction. After the pipelines are connected on site, the water tank is filled with water. After the gates are back down, the power take-off device is hung and the large pump and the mixing system are circulated. The operator or the driver must observe the power take-off shaft of the power take-off. There is no difference, whether there is oil leakage in the hydraulic pipeline. Third, cement cementing construction: When the chassis diesel engine and the diesel engine on the flameout, first determine that this fault occurs in the fuel system, according to the principle of easy first and then difficult to first check whether there is fuel in the fuel tank, the fuel tank ventilation hole is blocked. If there is no oil in the tank, it cannot be supplied, the vent hole is blocked, and negative pressure is formed in the tank, so the oil supply is not smooth. If there is no such problem, check from the low pressure oil line to the high pressure oil line step by step to see if the oil line is clogged with debris and if it enters air. The intake pipe, diesel filter, and oil-water separator of the diesel engine shall be inspected to prevent the air intake of the oil passage and the excessive contamination of the diesel filter element, resulting in the diesel engine stalling. Fourth, after the equipment back to the field of maintenance: After the vehicle returns to the field, be sure to clean all the equipment, because cementing cement often use brine cementing, corrosion of vehicles is relatively large. After the equipment is returned to the market, the equipment must be greased and maintained on the train platform in time. At the same time, the hidden dangers of the equipment can also be discovered in time through maintenance. The premise and basis for the use of machinery and equipment are the daily maintenance and maintenance of the equipment. During the use of equipment in different environments for a long period of time, parts of machinery wear, gaps increase, and changes in coordination directly affect the original balance of the equipment. The stability, reliability and use efficiency of the equipment will all be reduced to a certain extent, and even the mechanical equipment will lose its inherent basic performance and will not be able to operate normally. Only in the daily inspection and maintenance, we look for problems, discover problems, maintain various performance indicators through maintenance and other means, increase equipment utilization, prolong service life, and seek the most economic equipment life cycle costs, and pursue no accidents. The high efficiency ultimately provides a reliable guarantee for cementing construction.
A kick scooter is not only a joyful ride, but also the perfect transportation option for all ages to go working or riding around the neighborhood. The scooters we sell own a high coefficient of safety that they were made from a heat-treated aluminum deck and handlebars for long-lasting. Besides, the steel spring break at the back makes you stop quickly when you step on the back wheel, so you don't even need to worry about the safty problems. We will provide you the superior quality scooters and the color can be decided upon your requirements.
