The users of concrete pumps all know that when the equipment is in use, the vertical height and horizontal conveying distance of the pump have a direct relationship with the pressure of the concrete pump . If the pressure is too high, the vertical conveyance will be high and far away, otherwise the pressure will be small. Pumping is weak. The pumping strength has a direct relationship with the counterflow valve. The main function of the counterflow valve is to adjust the pressure of the pump . The concrete pump is mainly composed of a hydraulic system. The role of the counterflow valve is to regulate the flow of hydraulic oil. If the speed is high, the pump pressure is high and the speed is high. If the flow of the hydraulic oil is small, the speed is slow and the displacement is slow. Therefore, it is important to properly adjust the degree of the counterflow valve as required. If the counterflow valve is adjusted too large, it will not work. If the pressure is too high, the top of the oil pipe will burst, and it will not change. Therefore, when we use it, we must accurately adjust the counterflow valve to control the pumping pressure according to the different conditions on the scene, so as to bring convenience and benefits to us. The adjustment of the counterflow valve must not be performed blindly. It is necessary to gradually increase or decrease the flow of the hydraulic oil to reach the fixed-point discharge of the construction destination. This is to tighten the spare screw of the counterflow valve with a wrench. Do not let it Loose, in order to prevent running position during use, causing inconvenience to use.
