The concrete mixer truck is a special vehicle for construction engineering, which is composed of the chassis of the mixer truck and the upper part. The chassis of the mixer truck is the main part to support the weight of the whole truck. It is composed of the engine, chassis, cab and electrical equipment. The engine provides enough power for the whole truck. Whether a concrete mixer truck can run when it is full of concrete is insufficient, It all depends on the engine, so when you choose a concrete mixer, you must choose one with good engine quality and sufficient power. Of course, it does not mean that the greater the power, the better. You should choose it according to the volume of the mixing tank. The most important thing is that it is suitable. Such a choice is economical and practical; The chassis should be of good material and light weight, so as to support the weight of the whole tank; The cab should be larger and more comfortable as far as possible, because the driver of the concrete mixer is also very hard and spends a lot of time in the car. Some electrical equipment is almost the same. Although it's not hardware equipment, it's also indispensable. So we should pay attention to good maintenance at ordinary times. Only in this way can we get twice the result with half the effort and prolong its service life.
The so-called top loading is the mixing tank and its components. Generally speaking, the mixing tank is pear shaped structure. Its material should be high-strength carbon steel. The blade is the part of mixing concrete in the mixing tank. The blade should be thickened with double helix pairs, so as to ensure uniform mixing; The choice of hydraulic system is also very important. If the tank volume is 5 or 6 cubic meters, the hydraulic system should be made in China. If the tank volume is 10 or 20 cubic meters, the imported hydraulic system should be selected. However, the mixer with tank volume of 10 or 20 cubic meters cannot be licensed in big cities like Beijing and Shanghai, because these big cities have strict requirements on environmental protection; The tank body is equipped with a feeding and discharging device, which is composed of a feeding hopper, a discharging hopper, a main discharging tank, an auxiliary discharging tank, a bracket, a locking frame, etc. the feeding hopper receives the concrete from the mixing station and transmits it to the mixing tank, and the discharging port transmits the concrete discharged from the mixing tank to the pumping device. For example, the discharge port, feed port and the inside of the tank should be cleaned in time every time the concrete is transported. Otherwise, the concrete will stick to it more and more, which will damage these parts, reduce the volume of the tank, increase the weight of the tank, and ultimately reduce the service life of the mixer truck.
For the cleaning of concrete mixer truck, the first thing we think of is the internal and external cleaning of the tank. The concrete mixer truck transports cement, and the cement is easy to caking in a short time. Caking has a corrosive effect on the mixing drum, and the increase of caking will reduce the volume of the mixing drum. Therefore, it is necessary to keep the inlet wet before feeding each time, so as to reduce too much concrete sticking to the inlet, Every time after unloading at the construction site, the discharge port shall be cleaned, and then about 40L clean water shall be injected into the mixing drum to make the mixing drum rotate slowly for better cleaning. The blades in the mixing drum shall also be checked frequently to clean the attached concrete in time. Clean up the sewage in the mixing drum before loading. The outside of the tank should also be cleaned frequently.
The supporting wheels should also be well maintained. The supporting wheels of Dongfeng Shenyu Yuhu mixer should be lubricated regularly. The surface of the supporting wheels should be cleaned regularly and then oiled. In this way, the wear of the supporting wheels can be avoided and the service life can be prolonged.
The radiator of the concrete mixer truck is also the key point of maintenance. Check whether the fan of the radiator operates normally every day, clean the dust on the blade in time, replace the filter element of the radiator regularly, and keep the accuracy of the filter element consistent with the original filter element.
