The concrete pump pipes have pressure parameters, and different pump pipes are selected according to the delivery pressure of the pump truck. The pressure source of a fluid delivery system can vary. When the fluid is pushed through a filter, or the fluid is pushed through a flow meter or valve, or the fluid is pumped into a pressurized reaction vessel, back pressure is created. Before selecting pipes, you should first make sure that all pressure sources in the system have been clarified and the actual measured value of the total pressure of the system has been obtained. When selecting the pump tubing for the peristaltic pump, make sure that the pressure in the system does not exceed the recommended working pressure of the pump tubing. If the pressure is too high, the pump tube will swell and fit poorly with the pump head, resulting in rapid wear and failure. When the system pressure greatly exceeds the bearing capacity of the pump tube, the pump tube may even burst, ejecting fluid, and endanger safety. After selecting a pipe material, ensure that the pressure is maintained within the pressure range recommended by the manufacturer during use. If the system exceeds the maximum working pressure, a simple pressure relief valve or pressure switch can be installed to prevent excessive pressure accumulation. The function of the pressure slow release valve is: when the system pressure exceeds the set value, it will vent to the atmosphere to reduce the system pressure to a safe level. A more complicated pressure switch can also be used. When the pressure value exceeds the set value, it will turn off the equipment or sound an alarm device through a relay. When the system pressure exceeds the safety line, the above two methods are beneficial to safety.
