Small concrete mixer manufacturers to explain how to solve the problem of concrete mixing pump cut-off and speed?
For the construction personnel, in the process of concrete construction, they are afraid to encounter the problem of water cut-off of the concrete pump, which not only affects the construction progress, but also delays the construction period. So why does the water cut-off occur in the operation process of the concrete pump, and how can we solve the problem of water cut-off? The following is the answer from Xiaobian.
When the flow of concrete mixing pump is cut off, the reversing time can be shortened, and the running speed of main oil cylinder piston at the beginning of reversing can be accelerated. Constant power piston pump is controlled by electric proportion. By increasing the displacement of main oil pump, the quick reversing of distribution valve is realized, and the time from reversing to starting to push concrete is reduced. The distance between proximity switches is usually 5% ～ 10% of the total stroke, which should be adjusted according to the actual situation of concrete pump.
When the main motor of the small concrete pump can not reach the expected speed, it requires the staff to carefully check the power supply circuit of the concrete pump. Firstly, determine whether the voltage value and the rated power of the transformer are appropriate. Then check whether the voltage drop of the power supply circuit of the drum type mixing pump is appropriate. Otherwise, the large diameter cable needs to be replaced. The above reasons may cause the main motor of concrete pump unable to speed up.
Concrete mixing pump is a new type of urban construction tool that combines mixer and concrete pump. It is a kind of equipment that uses pipeline to transport concrete. It is used for mixing and transporting concrete in reinforced concrete structure construction. It is widely used in urban construction, high-rise building engineering, tunnel and bridge construction. Adopting concrete conveying mode can not only reduce the cost, but also save the construction time. It is your first choice to standardize the construction site.
