Concrete pump use

Concrete pump use

First, the use of concrete pump: use s leading valve commutation, can be satisfied with fine aggregate concrete delivery; glasses, plates and cutting ring made of high hardness and wear-resistant alloy materials, longer life expectancy; the outlet pressure level can be satisfied demand for construction and long-distance transport of construction; the choice of hydraulic oil cooling zy-510c stainless steel sheet bending machine for dies water cooling system, the cooling effect is good, using simple; fine aggregate concrete pump hydraulic system: double-pump hydraulic system is double circuit separates oil, the main oil pump selection variable column piston pump, to ensure smooth operation system, strong, and active and conditioning manual displacement, with pressure cut off and overpressure overflow feature, so that the main pump and the prime mover to get helpful maintenance, suck (back) oil suction filter selection (Back) filter, hydraulic oil filter to obtain reliable, clean, to ensure the normal operation of the system, to extend the use of life expectancy of hydraulic system components. Forced air cooling system fine aggregate concrete pump: concrete pump mixing the oil forced air cooling system selection, large radiator equipment, better habits site environment, to ensure the hydraulic system oil temperature in the normal operating range, and guarantee the host Hydraulic the system is in normal operating condition. Fine stone concrete mixing and dispensing valve system pump: Fine aggregate concrete pump hopper hopper depicted optimization, to ensure an outstanding suction resistance, with different standards for different materials, grizzly, and equipped with a vibrator fine aggregate concrete pump hydraulic motors use a large mixing system torque hydraulic motor, and the system not overpressure active rotation function, useful for maintenance of the hydraulic motor, and can take the initiative to eliminate the card appearance blender high wear large mixing blades, concrete segregation should not be deposited, in favor of suction. S pipe swing valve has a flow of clear, low resistance characteristics, high abrasion and wear face the choice of surfacing materials, the choice of transmission parts plating branded wear, in order to avoid similar products high-level transport hopper off-axis distortion and S valve representation, device selection support and sealing barrier layout, and enhance the use of life expectancy of fine stone concrete pump.

Fine aggregate concrete pump construction safety measures

Fine stone should be fixed firmly in place after the concrete pump, pumping should be checked before steering pump valve seal is good, the gap should be kept within the allowable range, so that a reflux slurry is reduced to a minimum. When the inspection found over bias application electrode wear welding. According to prescribed procedures in force test pump is operating normally after delivery. Pump start the program is: Start hopper stirring blade - lubricating slurry injection hopper - Open shut-off valves - actuated concrete pumps - lubricating pump into the pipeline - the hopper filled with concrete pumping test. Fine stone should be installed on the concrete pump hopper cnc wire spring coiling making machine ylsk-z650 screen isolated large stones, screen size and maximum aggregate size concrete match, and have someone monitor, find the bulk material, promptly removed. Pumping start, pay attention to the table and other parts of hydraulic concrete work state, generally at the outlet of the pump, prone to clogging. In case of blockage, the pump should be reversed, so that blockage concrete reflux, stirring it all and after pumping. If not effective, dismantle the pump should be shut down, clear blockage. Concrete should ensure a continuous supply. If not continuous feed, may slow down the pumping speed. When disconnected, the pump can not stop working, every 4-5 minutes, should be positive and negative rotation of the pump, piping mix to prevent agglomeration or precipitation, if the pumping stop more than 45 minutes, should be clear and clean and re-pumping . Fine aggregate concrete pumping concrete, should be continued to maintain a certain amount of concrete in the hopper, to prevent the hopper into the air, causing the concrete countercurrent, blockage is formed, if this problem, you need to pump reverses, the concrete hopper to return, After going out in the normal pumping air. Pumping, should change once every 2h wash tank of water, and check the pump cylinder stroke, are subject to change, time to adjust. To reduce the cylinder walls uneven wear, the best start the long journey. Only at startup and when concrete slump small short-range pumping concrete. When transporting concrete vertically upwards, due to water hammer, can make concrete reverse flow, decrease transmission efficiency, the higher the pipes, the more obvious. Workaround: Set between the pump and the stainless steel wc67y press brake bend machine vertical pipe section 10m above the level of tubes to counteract the momentum of the impact of falling concrete; concrete pump out near the spout plus stop valve. Construction of the high temperature, should be covered in the horizontal conduit 2 layer wet straw mat, anti-sunshine, and water regularly to prevent pipe blockage.
