1. Select the aggregate when the aggregate must control harmful impurities, it can be minimized. 2. The need to meet their own strength to a maximum particle size of the selected coarse and fine aggregate must not exceed three-quarters of minimum spacing of steel, concrete pump truck accessories wholesale, can not exceed the minimum structural surface becomes long-quarters a; 3. The maximum diameter of the need to refer the delivery tube inner diameter, concrete pump parts prices, because aggregate size too large lead to the delivery tube blockage, affecting the smooth pumping, it is generally to pump concrete aggregate The maximum size can not exceed one-third of the internal diameter of the tubing; wear glasses plate at the first occurrence of its central nose, the greater the gap between the glasses, plates and cutting ring, wear faster. Therefore must always pay attention to the gap between the glasses, plates and cutting rings, once found the gap increases, the need to immediately tighten the nut or replace worn parts shaped to prevent mortar into the friction surface. When the rubber spring loses its elasticity, to be replaced immediately. You can repair the cutting ring and glasses, plates, welding electrodes available after continued use. Luoyang Great Locomotive Equipment Co., Ltd. is the first professional, focus on the production of fine aggregate concrete pump manufacturers, with advanced production equipment, senior engineer of the R & D and production team and perfect after-sales service team. Welcome all the friends field guide! If mechanical manipulation, concrete pump parts manufacturers, generally bar system controls and flexible shaft steering mechanism in two ways. Shaft control mechanism have more advantages, such as layout flexibility, high transmission efficiency, transition joints and small air travel less convenient travel regulation, so fine aggregate concrete pump control system is mainly select shaft steering mechanism. For ease of operation, joystick are designed to be installed at a convenient location, fine aggregate concrete pump control system is mainly used to control the main pump flow and engine speed, concrete pump parts, thereby changing the concrete pump truck emissions. Luoyang Great Locomotive Equipment Co., Ltd. is the first professional, focus on the production of fine aggregate concrete pump manufacturers, with advanced production equipment, senior engineer of the R & D and production team and perfect after-sales service team.
