Since various new materials of vehicles are now widely used, the service life of concrete pump trucks is much higher than that of the former. When concrete pump trucks pump concrete, it is because Into the car, there is a relatively violent friction between the metal and the mechanical metal. The friction is heavy and has a close relationship with the pumping speed, concrete marking, concrete concrete formula If there is more aggregate in the concrete, then the ratio of sand to cement is less, then the friction will increase. However, the force of friction and the speed of pumping until now is no more stringent evidence to prove the relationship between them, is to observe in accordance with some of our common sense, to use the piston movement inside the engine as an example, if the piston moves The faster the speed, the smaller the friction should be. However, regardless of the relationship between these data, we can be sure that this friction will cause the wear of multiple parts inside.
As the concrete enters the hopper from the feed, this mutual friction begins. It also includes the mixing blades inside the hopper, the hopper and in some aspects, the concrete into which the helium tank, and then in the S tube, and finally in each duct, these various parts and the intimacy between the merchants Contact and friction will eventually lead to shortened service life between them. However, some new technologies have now been added to these technologies, such as a certain brand of 56-meter concrete pump trucks. Manufacturers have said that the service life of all their own parts will be extended: small bends, large bends, The time limit for the straight pipe and hinged elbow can reach 4-60000 squares; the time limit for the helium piston can reach 2-30000 squares; the time limit for the use of the eyeglass plate can reach 5-80000; the time limit for the use of the transfer cylinder can be 10 ~14 million square. So. Based on the service life of various parts of the concrete pump truck, and based on the price of the concrete pump truck , we can well calculate how much the investment returns. (Text / Sun Ni)
