Under what conditions are the high pressure and low pressure of Sany pump truck used respectively?

High pressure is generally used in high-rise buildings, or the material is poor. This can be seen from the pumping pressure, which is generally above 20MPA, which is converted into high pressure! In the case of poor concrete or high output height, high pressure is used, which is characterized by short stroke and high main cylinder pressure, so the beating speed is relatively slow.

Usually, the workplace is relatively flat and low pressure is used. Low pressure is faster and more fuel efficient. Large low-pressure displacement and small high-pressure displacement.

Pump pipes are generally divided into 125 and 150 and 80, which have high pressure and low pressure respectively. 125 the low-pressure model of the pump pipe is a pipe with an outer diameter of φ 133, and the high-pressure model is a pipe with an outer diameter of φ 140. 150 the low-pressure model of pump pipe is the pipe with external diameter φ 159, and the high-pressure is the pipe with external diameter φ 168.

The pipe head of the pump pipe is a specially processed pipe joint, which is connected with the pipe body by welding. The connection of each pipe is connected by a pipe clamp processed by precision casting technology.
