Schwing Concrete Pump Hydraulic Diagram PDF

As a non-professional person may have a headache with the complex structure of Schwing concrete pump hydraulic diagram, this article takes you in the simplest language to quickly understand the pump diagram and learn how to choose a size.

First of all, you should know that concrete pump hydraulic is composed of hopper, pump body, diaphragm, control valve, water pump and water tank, etc. Its operating principle is: the diaphragm is in the pump body, when the water pump pumps the water under the diaphragm back to the water tank through the control valve, the diaphragm sags, and the concrete in the hopper presses open the check valve into the pump body; When the water pump pumps the water in the tank back to the pump body through the control valve, the pressure water makes the diaphragm rise, close the check valve, and press the concrete into the conveying pipe for discharge.

In addition, concrete pump hydraulic has many different models, we generally choose the model according to the working condition requirements, estimate the resistance of the pipeline, select the concrete pump model according to the calculated pressure value, and finally confirm whether the pumping pressure (determines the pumping height) and the theoretical amount (determines the pumping time) meet the construction needs according to the construction requirements provided by the manufacturer. At present, there is no mature method for estimating the pressure of high-strength and high-performance concrete pumping. We preliminarily estimate the pumping pressure according to the calculation method recommended by JGJ/T10-95 "Technical Regulations for Concrete Pumping Construction": S. Morinaga's formula method. The reason is that the pressure loss value calculated by this formula is too large, which is in line with the characteristics of high strength and high performance concrete pump hydraulic.

Here I will give an example to explain to you: r stands for the radius of the delivery pipe, r = 0.0625 (m). K1 stands for adhesion coefficient (Pa), we let K1 = (3.0-0.10S1).102, K2=velocity coefficient (Pa/m/s) K2=(4.0-0.10S1).102. T2/T1 represents the ratio of the distribution switching time to the piston push concrete time, whichever is 0.2. V represents the average flow rate (m/s) of concrete in the conveying pipe. α represents the ratio of radial pressure to axial pressure of concrete, α=0.9. △PH=0.035MPa/m (horizontal). According to preliminary calculations, the vertical height is 432.5 (m)×2×0.035=30.28 MPa, the horizontal pipeline is expected to be 100m×0.035=3.5MPa, and the empty machine pressure: 1MPa. Therefore, the outlet pressure of concrete pump should be at least greater than 30.28+3.5+1=33.78MPa. According to this result, taking into account factors such as slump loss, pipe routing, concrete fluctuations, etc., a factor of 5% is reserved. The pump outlet pressure is at least 35.47 MPa; That is, to choose a concrete pump above 35.5 MPa. For outlet pressure more than 35.5 MPa, check the type spectrum of concrete pumps at home and abroad.
