How much does concrete pump cost? This is a problem many purchaser will ask every day. With the construction of cities, towns and new rural areas, concrete pumps are highly targeted, they have been well received by the majority of users. In the current economic trend, the construction of commercial buildings, railways and bridges market environment, the concrete pump have huge strong market demand.

In order to ensure normal transportation, fly ash and water reducer should be added to the concrete to enhance the workability of the concrete. If concrete conveying is to convey more than 500 meters, the maximum particle size of concrete should not exceed 30 mm as far as possible (the limit should not exceed 40mm, and the amount of 30-40mm should be less to prevent the pipe from being blocked during the conveying process). For underground transportation, due to the long transportation time of the concrete pump, it is recommended to prepare dry concrete (sand, gravel, cement ash) on the well, and then mix it with a forced concrete mixer after transportation to the underground, then charge into the concrete pump for direct pumping, this can ensure that the concrete is easy to transport, and it is not easy to block the pipe.

The hydraulic concrete pump cost is higher than mechanical concrete pump cost. The hydraulic concrete pump consists of hopper, hydraulic cylinder and piston, concrete cylinder, distribution valve, S-shaped pipe, flushing equipment, hydraulic system and power system. The hydraulic system uses pressure to push the piston back and forth. When the piston moves backward, it sucks the material, and when it is pushed forward, the concrete in the concrete cylinder is pressed into the conveying pipe through the S-shaped pipe. After pumping concrete, clean the concrete pump body and delivery pipe with high-pressure water or compressed air. The displacement of the piston concrete pump depends on the number and diameter of the concrete cylinder, the reciprocating speed of the piston and the volumetric efficiency of the concrete cylinder suction.

Check and keep the manual grease pump oil tank full of grease before starting the machine and after washing the whole car after pumping. Pull the handle of the grease pump and observe that there is clean grease overflowing from the stirring bearing and the shaft head of the size of the S tube. During the working process, pull the handle of the manual grease pump 10 times every 1 hour. The concrete pump lubrication system should be kept clean to prevent the entry of dust and other impurities, and do not contact with acid-base substances, and the system should be cleaned every 500 hours of operation. When the coating (0.2-0.25mm) of the conveying cylinder is not worn off and concrete slurry or sand appears in the rear of the concrete piston, that is, the water tank, it indicates that the piston has been worn and the concrete sealing body, guide ring and dustproof ring should be replaced immediately.
