Usually fine aggregate concrete pump in an interview with the raw material, power unit driving planetary roller rotation, rolling hose squeeze squeeze inside the concrete pipe exhaust duct. When the pump water through the control valve diaphragm below withdraw tanks, diaphragm subsidence, concrete hopper pressure to open the check valve into the pump; pump when the water in the tank through the control valve to withdraw the pump, pressure water to make diaphragm rises, the check valve will close pressed into concrete ducts discharge. Fine aggregate concrete pump vacuum system will pump body to maintain a certain degree of vacuum hose extrusion promote restitution immediately after rolling, and concrete hopper accelerate inhalation, extruded hose. In general, fine aggregate concrete pump displacement was more dependent on the radius of gyration and the rotation speed of the rotor, squeeze the hose diameter and concrete inhaled volumetric efficiency. Luoyang Great Locomotive Equipment Co., Ltd. is the first professional, focus on the production of fine stone concrete pump manufacturers, with advanced production equipment, senior engineer of the R & D team and perfect after-sales service team. Welcome friends to guide field trips! 1, the pressure of the valves in the hydraulic system when the new machine factory concrete pump concrete pump it is set, the user should not mobilize. 2, in the cold season, the construction of small concrete pumps, to take freezing measures; construction in the hot season, to prevent excessive oil pump concrete structure, when the temperature reached 80 ℃ should stop running. 3, pumping is completed, to promptly hopper, valve boxes, concrete cylinder pipes clean. After cleaning the pump, disconnect the power supply concrete pumps, each switch in the off position to stop or not allowed to tamper with.
