Knowledge points for pump truck stability

1. The hydraulic system of the long-boom pump truck adopts a closed system, the closed circulation of the oil inside, the reversing of the swash plate, the unnecessary valve group is reduced, the pressure is not lost, and there is basically no commutation impact.

2, Boom ergonomics, this is very important, if the 4 5 6 boom is too long, then according to the principle of leverage, when the concrete is delivered to the end, the weight is equivalent to double, the jitter is naturally increased.

3 Flexible pumping technology, many people do not know what this is, in simple terms, is to design a pressure relief circuit at both ends of the hydraulic cylinder, the cylinder stroke no longer impact when the end of the stroke. The layman feels that the noise is small and weak, in fact, it is protecting the entire pumping system.

4, The operator generally likes to play fast and fast, but I don't know if it is irresponsible to the owner, the mechanical things, the jitter is large, the fatigue life of the steel is naturally shortened, the structural parts are long-term vibration, not far from the broken arm and the falling frame.

5, There is one point in the flexible pumping, that is, intelligent anti-blocking. The operator generally believes that the force is bigger, and naturally it is possible to knock out the fast-blocking concrete. The result is exactly the opposite. The more gambling, the more dead, until the tube bursts. After adding the smart sensor, when the pumping pressure rises, the system judges that there is a sign of blockage, and the counter pump will be hit in time. This is much better than a stupid beggar, and the bosses can decide for themselves.

6, Turret speed and pumping frequency can be adjusted, but the new car running-in period, the manufacturer will set to low speed, pumping frequency is 22 ~ 25 / minute, if a factory set to 31 / minute, it is recommended that the boss Let's adjust it ourselves. Safe and risk-free construction is more important than anything else.

7, Do not shake, naturally do not throw material, although not much, but accumulation, a year save a few hundred square or ok, that is hundreds of thousands of friends!

8, Some manufacturers advocate the boom vibration limiter, all-round limit shake, in fact, should shake.That's not the point.Have a problem to get rightness medicine, and add outside force control, belong to the end put the cart before the horse, such can hold back inside injury, more hold back more heavy.
