Mine concrete pump Scope The new coal mines with concrete pump

Mine concrete pump Scope The new coal mines with concrete pump is based on the coal mine roadway Chamber and narrow space, equipment must be explosion-proof reality designed with concrete pump. The pump electrical power source is only one explosion-proof motor, all of the action of other hydraulic actuator control and complete. The pump has a small volume is a significant feature of the pump is handling convenient. Mine is the use of concrete pump the durable movable volumetric cement mixer finished pouring concrete through the pipeline to the site. Concrete pouring works mainly used for coal mine roadway Chamber and can also be used for other projects in the concrete delivery and pouring operations. Such as tunnels, bridges and culverts, ground construction.Fine aggregate concrete pump worksFine aggregate concrete pump is a pressure-fed through a pipe concrete, horizontal and vertical transportation and pouring of concrete construction machinery. The basic principles of fine aggregate concrete pump is driven by an electric motor driven oil pump produces pressure cylinder, cylinder rod drive concrete cylinder piston is pushed into the concrete pipes, concrete action by the order of allocation between the valve and the master cylinder, and constantly from the concrete Concrete hopper suction concrete cylinder and transported by pipeline to the pouring site.Concrete pump operation1, numeral cement, sand grain size and mix the factory should be required to meet the mechanical properties specification requirements for pumps. 2, parking brake and locking brake pumping equipment shall be used simultaneously, tires should wedge, water supply and water tanks should be properly stocked with water, should be no debris in the hopper, foam concrete mixer price the lubrication points should lubricate properly. 3, ministries bolts should be tightened pumping equipment, pipe joints should be tightened sealed, protective equipment should be complete and reliable. 4, at the beginning of each part manipulate, adjust the hand wheel, lever, handle, cocks, etc. should be in the correct position. Hydraulic system should be normal without leakage. 5, ready for cleaning pipes, cleaning supplies and other related devices. Before the job, you must use the required cement mortar formulated lubricating pipe. Unrelated persons must leave the pipeline. 6, the legs should be fully extended and supported the prison, not fixed may not start before the boom. After the boom raised bracket before rotation. When the order boom should extend. Do not use boom lift or drag objects. 7, when the boom is fully extended state, non-moving body. When a job needs to be moved, it should be fixed on the segment boom collapsed, moving no faster than 10km / h. Boom may not use more than a predetermined diameter pipe, tube should be attached to the wheel off prevention safety rope system. 8, should be ready to monitor a variety of instruments and indicators, if not normally found, to promptly adjust or treatment. 9, when the pumping system under pressure, can not open any pipelines and hydraulic pipes. Safety valve of the hydraulic system must not be adjusted. Accumulator filled only ammonia. 10, after the job must be concrete and pipes cm140g gas mini portable concrete mixer inside the hopper full output, and then the pumps, hoppers, pipe cleaning. When flushing pipes with compressed air, the outlet end of the pipe within 10m can not stand in front of people, and applications and other metal basket to collect out of foam rubber and sand grains. 11. Do not use compressed air to flush boom pipe. In order to fold contraction boom ended. 12, various parts of the hand wheel, control sweat, operate the switch, adjust the handle, cocks, etc. should be reset. Hydraulic unloading system.
