Problems solved by technology
This length of the conveying pipe poses the problem that even the smallest interruption of the conveying flow of the pasty material results in a huge oscillating movement of the conveying pipe due to inertia
Furthermore, although the drive cylinder is not "in-line" after the delivery cylinder, but in between, the balancing cylinder still requires a lot of space, making it difficult to place and adequately secure the balancing cylinder on the concrete pump truck
Furthermore, such balancing cylinders are expensive, complex and very heavy components

Embodiment Construction
[0084] figure 1 The pump unit shown for conveying pasty materials consists of a piston pump with two cylinders, in figure 1 Only one cylinder 1 of the piston pump is shown in the illustration. The cylinder has a piston 2 which is here in its end position. The cylinder is connected to a prefill container 5 via an inlet 3 which can be closed off via an inlet slide valve 4 . Furthermore, the cylinder has an outlet 6 which can be closed off by means of an outlet slide 7 . The cylinder 1 is connected to a delivery pipe 8 through an outlet 6 . In its area adjacent to the piston pump, the delivery line 8 is configured as a so-called "fork", ie a pipe branch, which brings together the delivery flows of the individual cylinders of the piston pump and leads them to the end of the delivery line. In a part (not shown) the individual subflows of the individual cylinders of the piston pump are conveyed together in a conveying line.

The invention relates to a method for conveying pasty materials by means of a pump device comprising a piston pump with at least two cylinders, each of which has a piston, wherein each cylinder is pumped by means of a The inlet closable by the inlet slide valve is connected to the prefill container, and each cylinder is connected to the delivery pipe via an outlet closable by means of an outlet slide valve assigned thereto, in this way, during the suction stroke of the cylinder With the inlet open and the outlet closed, the pasty material is conveyed from the prefilled container into the corresponding cylinder and, during the pumping stroke of the cylinder with the outlet open and the inlet closed, the pasty material is delivery into the delivery pipe; the piston speed during the suction stroke is greater than the piston speed during the pumping stroke; at, near or shortly after the end of the suction stroke, the inlet is closed by means of the inlet slide valve and thereafter, the outlet is opened Before that, compress the pasty material in the cylinder.
Description
technical field [0001] The invention relates to a method for conveying pasty materials by means of a pump device comprising a piston pump with at least two cylinders, each of which has a piston, wherein each cylinder passes through an inlet assigned to it Connected to a pre-filled container, and each cylinder is connected to a delivery tube through its associated outlet. Furthermore, the invention relates to a pump device for conveying pasty materials, which comprises a piston pump with a cylinder having a piston and which is connected to a prefill container via an inlet which can be closed by an inlet slide valve. Background technique [0002] In the conveying of concrete, pump devices are used which are usually constructed as piston pumps which have two cylinders each with a piston. In a so-called suction stroke, the cylinder sucks the pasty material to be conveyed from the prefilled container and thereafter conveys the sucked pasty substance into a delivery line connecte...
