Concrete pumps produced by in Daswell machinery are widely applied to the building construction concrete mixer, bridge, tunnel, harbor, wharf and other concrete engineerings, which are the construction equipment of low costs and high production. Henan Daswell machinery gives the brief introduction of the hydraulic performance characteristics of concrete pump.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:concrete mixer price,concrete batch mix plant,Ready-Mixed Concrete Making Plant,If you are interested in our products, please contact us freely: sales@daswell.com 1. Concrete pump adopts hydraulic directional control direction valve with famous brand. And the excellent quality of concrete pump makes the concrete pump have features of high efficiency, , long service life, stable performance and long time and continuous operation. Daswell concrete pump machine adopts foreign imported oil pipe and original pipe joint and has stable performance, which increases the rate of flow and reduces the possibility of oil impregnate without increasing the pipe diameter of the system. 2. The pumping return circuit of concrete pump adopts open type hydraulic system, which can avoid the hydraulic impact in the process of reversing. There is no impact and peak valve and the control of temperature is ideal. 3. The piston rod sealing of master cylinder in the concrete pump adopts imported combined sealing, which has features of good sealing effect and strong waterproof performance; the piston sealing adopts multiple-channel piston ring which is durable in use. 4. The swing cylinder adopts piston cylinder, which has advantages of good sealing and buffering effect and can guarantee the long time and stable operation of concrete mixer. 5. The lubrication system of concrete pump adopts full-automatic oil addition multiple filtering technology skip type concrete mixing plant, which can effectively prolong the service life of easily damaged parts.
