Claims (1)

Конструкцией шламового насоса с нагнетательными цилиндрами, в частности для двухцилиндрового бетононасоса с управлением потоком густой массы между загрузочной воронкой, двумя нагнетательными цилиндрами и нагнетательным трубопроводом, а также схемой соединений, управляющей приводами нагнетательных цилиндров и потоком густой массы, и управляющей заслонкой, а также компенсационным цилиндром, который исключает прерывание потока густой массы во время переключения управляющей заслонки, предусмотрено, что схема соединений позволит ускорить работу привода соответствующего нагнетающего цилиндра, увеличить количество густой массы, принятой компенсационным цилиндром, и замедлит переключение управляющей заслонки так, что одна из заслоночных пластин, назначенных каждому нагнетательному цилиндру на обеих сторонах входного отверстия управляющей заслонки, величина которой соответствует площади между отверстиями нагнетательных цилиндров, таким образом, что в среднем положении управляющей заслонки отверстие нагнетательных цилиндров заслонено пластинками заслонки и входное отверстие в управляющей заслонке закрыто на площади между нагнетательными цилиндрами для проведения частичного хода поршня нагнетательного цилиндра, уплотняющего всосанный бетон, при этом отверстие нагнетающего цилиндра также закрыто.The design of a slurry pump with injection cylinders, in particular for a two-cylinder concrete pump with a dense mass flow control between the feed hopper, two injection cylinders and a discharge pipeline, as well as a wiring diagram controlling the actuators of the injection cylinders and the thick mass flow, and the control valve, as well as a compensation cylinder , which eliminates the interruption of the flow of thick mass during the switching of the control valve, it is provided that the circuit diagram will allow us The operation of the drive of the corresponding injection cylinder, increase the amount of thick mass adopted by the compensation cylinder, and slows down the switching of the control valve so that one of the damper plates assigned to each injection cylinder on both sides of the entrance of the control valve, the value of which corresponds to the area between the holes of the discharge cylinders, in such a way that in the middle position of the control valve, the hole of the discharge cylinders is obscured by the flap plates and the input th hole from the control damper is closed on the area between the injection cylinder to perform a partial stroke of the injection cylinder sucked compacting concrete, thus pressurizing the cylinder hole also is closed.
