Concrete mixer truck feeder Notes Concrete mixer truck

Concrete mixer truck feeder Notes Concrete mixer truck to concrete pump when feeding, should meet the following requirements: 1. Before feeding, the high-speed rotating mixing drum, the concrete mixing uniformity; 2. When feeding, pumping even reverse the discharge should be fit and should remain within the concrete hopper height above the mark; 3. Interrupt feeding operation, dasiona7 concrete mixer truck made in china should make low-speed mixing concrete mixing drum; 4. The job is completed by the vehicle driver, non-driver personnel to operate strictly prohibited. 5. concrete pump hopper, should be placed mesh sieve and let someone monitoring feeding to prevent the particle size is too large aggregate or foreign objects into the pump causing blockage; 6. forbidden to quality does not meet the requirements of concrete pumped into the pump. 7. The concrete mixer truck feed has been completed, should be promptly cleaned mixing drum side by side to make water. Concrete pump pumping principle When concrete cylinder two pistons are connected to the two master cylinder piston rod, in the role of the master cylinder hydraulic oil, for reciprocation, a cylinder advancing, the other cylinder back; concrete concrete mixer truck 12m3 with free parts cylinder communicating with the hopper outlet, one end of a dispensing valve discharge port, and the other end by a spline shaft and arm joints, under the action of the swing cylinder, you can swing around. When pumping concrete material, in the role of the master cylinder, a piston forward concrete, other concrete piston back while swinging action under the fuel tank, dispensing valve in communication with a concrete cylinder, another concrete cylinder in communication with the hopper. Such concrete piston back, put concrete material hopper suction concrete cylinder, another concrete piston forward, the concrete cylinder to pump concrete into the dispensing valve.        When the concrete piston back to the stroke end, trigger change in the tank means reversing direction, master cylinder, while the swing cylinder commutation, the dispensing valve cylinder communicating with concrete, concrete cylinder communicating with the hopper, then the Pistons a retreat, a branch forward. This cycle, in order to achieve continuous pumping. When the anti-pump, by anti-pump operation, so in the intake stroke of concrete cylinder and a dispensing valve in communication, in the push stroke concrete cylinder communicating with 2015 10 cubic meters concrete mixer truck the hopper, which will withdraw the line of concrete hopper
