With the rapid development of the domestic construction industry, the concrete pump truck is also driven by various construction projects to increase the frequency. Concrete pump trucks have high requirements for drivers and technicians. In the case of not just understanding the car, it is also necessary to be able to deal with various vehicle breakdowns. What are the common breakdowns of concrete pump trucks in daily use? 1. In the course of continuous work of concrete pump trucks for a long period of time, there will generally be a reversing pressure shock, because the main hydraulic circuit of the pumped hydraulic system is a closed circuit, and in general it is In a high-pressure and high-flow state, if the pumped system fails, the oil temperature of the concrete pump truck will rise. After the oil temperature rises, it will cause the following kinds of failures: 1, leading to a serious leak inside the hydraulic system 2. The pressure caused by the overflow valve is too high or the relief valve is set to not discharge 3, resulting in excessive dust accumulation in the cooler and poor heat dissipation from the heat sink The fan that caused the cooler to stop turning 5, causing the cooler to suddenly block 6, resulting in low pressure relief valve pressure is too high or damage 7, resulting in no load on the boom hydraulic system 8, the amount of hydraulic oil is not enough If the oil temperature of the hydraulic oil as long as it is more than the normal value of the case need to be checked in accordance with the above situation. Second, the concrete pump trucks are equipped with lubrication equipment. The pumping system can complete the grease transportation once after each round of the distribution valve. After passing through the grease distribution valve into the stirring bearing, it can play a role of lubrication and sealing. If it is observed that there is leakage of slurry and abrasion in the agitator shaft, it should be checked first whether the oil filter screen is clogged. There is no oil in the joint of the grease tube. The grease supply system is Not all of them are operating normally. The distribution valve has not lost its assigned performance. As long as the wear is determined because the components in the mixing system are caused by prolonged use, they should be replaced in time. Third, the addition of the speed of the stirring shaft is found to have a significant decline or is not rotating conditions, should immediately check the next stirring hydraulic motor is not able to normal operation, and the pressure of the mixing hydraulic system is not in a normal Reasonable values, but also can properly speed up the stirring shaft to test. (Text / Sun Ni) The anti-theft Wheel Nut & Bolt Kits are more and more popular now which are also known as an anti disassembly screw, which is used for preventing the theft of a vehicle which park in an outdoor public place. This kind of screws need to use special tools to take out, play the role of anti-theft. It's expensive to buy the alloy wheels, but it's economic to buy the Wheel Nut&Bolt Kits. So it's worthy of buying one set of Wheel Nut&Bolt Kits to protect your alloy wheels from stealing.
