The diesel powered concrete mixer pumps integrate mixing, pumping and transportation functions, can independently complete the mixing, transportation and pouring of concrete. Its power source is a diesel engine, and no external power supply is required, which is suitable for construction sites with inconvenient power supply.

Working principle of diesel powered concrete mixer pump:
- Mixing system: The diesel engine drives the agitator in the mixing tank to ensure uniform mixing of concrete, improve strength and workability.
- Pumping system: The hydraulic system (powered by the diesel engine) drives the piston pump to push the concrete to the construction site through the conveying pipeline. The distribution valve (such as the S-type valve) optimizes the flow direction of concrete and reduces the risk of pipe blockage.
- Conveying capacity: Some models can achieve 200 meters of horizontal transportation or 70 meters of vertical pumping to meet the needs of high-rise buildings, bridges, etc.

Main technical advantages of diesel engine concrete mixer pumps:
1. Power and environmental adaptability
- No power dependence: The diesel engine provides autonomous power, which is suitable for remote areas, rural construction and construction sites with insufficient power.
- Quick start and shutdown: The diesel engine can start and reach full power operation in a few seconds, and the shutdown process is short, which is suitable for the construction rhythm of frequent start and stop.

2. High efficiency and energy saving
- Fuel economy: The thermal efficiency of diesel engines reaches 30%-46%, and the fuel consumption is lower than that of traditional power equipment, and some models save more than 30% of energy.
- Hydraulic system optimization: The use of international brand hydraulic components (such as Rexroth, Kawasaki), combined with high and low pressure switching technology, reduces energy consumption and improves reliability.

3. Outstanding construction performance
- High pumping efficiency: Some models can pump up to 40 cubic meters per hour, which is much higher than the manual pouring speed.
- Anti-blocking pipe design: Through S-type valves, floating sealing technology and reverse pumping functions, the probability of pipe blocking is reduced, and it is suitable for high-grade concrete transportation.

4. Mobility and convenience
- Flexible mobility: The drag pump design is easy to tow and transfer, the vehicle-mounted pump can quickly switch the construction site, and the outriggers occupy a small area and adapt to narrow spaces.
- Easy to operate: High degree of automation, only 1-2 people are required to operate, equipped with a remote control or intelligent control system to reduce labor costs.

Typical application scenarios of diesel powered concrete mixer pumps:
- Construction in remote areas
Scenarios with insufficient power coverage such as self-built houses in rural areas and slope protection of mountainous roads, diesel engine drive ensures construction continuity.
- High-rise buildings and large projects
Suitable for high-rise concrete pouring (such as buildings over 300 meters), diesel power provides stable high-pressure pumping capabilities.
- Emergency projects and harsh environments
During power failures or extreme weather, diesel engine pumps can still operate normally to ensure that the construction period is not affected.

Maintenance and costs of diesel powered concrete mixer pumps:
- Easy maintenance: The diesel engine has a compact structure, low cooling water demand, and low daily maintenance costs.
- Long-term economy: Although the initial purchase cost is high, fuel efficiency and equipment utilization can reduce the overall construction cost.

Diesel powered concrete mixer pumps have become the preferred equipment for construction without electricity or in complex environments due to their power autonomy, efficient pumping capacity and wide applicability. When selecting a model, it is necessary to comprehensively consider the construction requirements, machine parameters and maintenance costs, and give priority to brands with mature technology and universal accessories. For long-term projects, diesel-electric dual-purpose models can be considered to balance energy saving and flexibility.
