Small concrete pump is a kind of machine, which is used to convey concrete continuously along the pipeline. And it has played an essential role in conveying concrete. Under the current circumstance of sluggish economy, big city commercial housing construction, railway construction, bridge construction are in frustration, therefore, the small mobile concrete pump is in great demand. And small concrete pumps are widely used to convey mortar, small aggregates, refractory materials, thermal insulation materials, greening soil in ecological environment construction and plain concrete, fiber concrete in various kinds of engineering projects.
Working principle of small concrete pumps for sale
The pumping system of small size concrete pump is driven by electric motor or diesel engine, the concrete throughput can be adjusted automatically by the hydraulic system or manual control. Pumping system consists of six parts: hopper, mixing system, concrete distributing valve, concrete conveying cylinder, washing chamber and master cylinder.
Actually, the working process of small concrete pumps for sale is suction and discharge of the concrete by pressure. When the pressure oil of the hydraulic system enters into the master cylinder, the piston rod stretches out,;
At the same time, the pressure oil passed the communicating pipe makes another piston rod retract, when the concrete conveying piston connected with the piston of the master cylinder retracts, it will have a self priming effect on the conveying cylinder, and the concrete in the hopper will be inhaled into the conveying cylinder by guiding valve under the effect of air pressure and mixing blades.
Meanwhile, another oil cylinder under the effect of the oil pressure pushes the piston rod of the master cylinder to stretch out, and drives the concrete piston to push out the concrete in the conveying cylinder, and enters into the concrete conveying pipeline through the guiding valve conveying mouth Y pipe.
A concrete pump is a machine used for transferring liquid concrete by pumping. There are two types of concrete pumps.
The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom. They are a revolutionary alternative to line-concrete pumps.
The second main type of concrete pump is either mounted on a truck or placed on a trailer, and it is commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home concrete slabs and most ground slabs.
There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialized jobsites such as mines and tunnels.

XBS25-12-33:
Adopts XBS25-12-33 fine stone concrete pump for transporting mortar. The comparison of mortar and fine stone transported by fine stone concrete pump and mortar and fine stone transported by construction elevator:
,: , , , 3.2m2, .
As for the same working condition and construction structure, let's take the ground handling of one site in Qingdao city as an example: Both of them have three units with 32 floors and the total area is 32000 m2, the following is the comprehensive comparison between fine stone concrete pumps and construction elevators for conveying.
1. Personnel allocation for fine stone concrete pumps as shown as the following:
1, 2(4), 2, 2, 2, 4, 15.
One fine stone concrete pump operator, two sets of blenders and two operators for each blender (totally 4 persons), two persons for concrete supplying, two persons for ground cleaning, two persons for concrete pouring, and four persons for smoothing ground, totally 15 persons.
, 12m³/h(, 20m³/h), 12m³/h*8h=96m³, 5-6cm, 1920, 128, 17.
Generally, the average conveying capacity is 12m³/h (the data includes machine shut down time, and the theoretical conveying capacity of fine stone pump is 20m³/h), conveying capacity of every day is 12m³/h*8h=96m³, and construction surface is 5-6cm in thickness, so every day can make 1920, and the average work for each people is 128, which totally needs 17 days for finishing this work
2. Personnel allocation for construction elevator is shown as the following:
2/2/2/8/2/4/2, 22., 6, 120.06m³, 1612, 8, 12*0.06*8*4=23m³, 460, 21, 70.
Two persons for two sets of blenders, two persons for concrete supplying, two persons for carrying sand and stone, 8 persons for transportation, two cleaners, four persons for concrete pouring, and two persons for ground smoothing, totally 22 persons. Usually, construction elevator can carry two transporting vehicles at each time, low-rise floor costs 6 minutes and high-rise floor takes 12 minutes for one lifting and each vehicle can carry 0.06m³, so each hour there can be 12 vehicles in 6 times of transporting, if we take 8 people divided into four groups for counting: 12 vehicles *0.06*8*4=23m³, so every day can have 460 and per capita is 21, which needs 70 days for finishing this work.
