Concrete trailer pump is a very common mechanical equipment in construction. It has a smart body, easy to drag, economical and cheap, so it is welcomed by the majority of construction parties. Compared with other concrete pump types, trailer concrete pumps need to be installed in order to carry out construction during use, and certain skills need to be paid more attention to. The trailer concrete pump can be towed to the work site with a tractor by tires. Operating costs are relatively lowest among the concrete pump types.
A concrete trailer pump has the following main technical parameters: delivery capacity, outlet pressure, motor power and distribution valve form. According to the new national standard, these main parameters can be obtained from the model of the concrete pump. The motor power of a trailer concrete pump is the prerequisite for determining the outlet pressure and the delivery volume. When the motor power is constant, the pressure The increase of, will inevitably reduce the delivery volume; on the contrary, reducing the outlet pressure will increase the delivery volume.
In order to ensure that the concrete trailer pump must have a large delivery volume, but also have a certain outlet pressure and matching economic power, in the design of the trailer concrete pump, most of the constant power plunger pumps are used; that is, the constant power value after selection, when the outlet pressure increases, the output displacement of the oil pump will automatically decrease to reach the value corresponding to the power design. If you want to achieve high outlet pressure, but also want to achieve the purpose of large delivery volume. The only way is to increase the motor power. Therefore, in the new national standard, the concept of the capacity index of the concrete pump is cited (in MPa·m3/h); that is, the product of the actual outlet pressure of the concrete pump and the actual delivery volume per hour, the greater the value, The greater the capacity index, the greater the power of the motor, thereby achieving the purpose of large displacement and high head.
