A portable concrete mixer pump with diesel engine is a highly efficient mechanical equipment designed for construction sites. It integrates concrete mixing and pumping functions, and is particularly suitable for remote areas where electricity supply is inconvenient or there is no stable power supply. This equipment is usually equipped with a powerful diesel engine that can provide sufficient power to drive the hydraulic system to achieve concrete mixing, conveying and pumping operations.

Working principle
The working principle of portable concrete mixer pump with diesel engine is based on hydraulic transmission technology. The diesel engine and the oil pump form a transmission match. The oil pump extracts the hydraulic oil in the oil tank into the hydraulic valve group, and provides hydraulic oil to the hydraulic cylinder, hydraulic motor and hydraulic lifting device through the first outlet valve, the second outlet valve and the third outlet valve respectively. This allows the mixer to adjust the center of gravity, complete the mixing of concrete, and raise or lower the hopper.

Application scenario
This type of concrete mixer pump equipment is widely used in construction projects, such as residential buildings, commercial buildings, bridge construction, etc., and is particularly suitable for use in rural areas or places with complex construction site conditions. They can effectively solve the problems of concrete mixing and transportation, and are very suitable for small to medium-sized construction projects due to their portability and self-sufficient power source.

Main parameters and technical features of portable concrete mixer pump with diesel engine:
- Productivity: Different models have different production efficiencies. For example, some models have a maximum theoretical output of 40 cubic meters per hour.
- Maximum vertical and horizontal conveying distance: Depending on the specific design, some models can achieve a maximum vertical conveying distance of 160 meters, while the maximum horizontal conveying distance can reach 500 meters.
- Distribution valve form: Many modern concrete mixing pumps use S-tube valves as distribution valves. This design helps to improve sealing performance and simplify the structure.
- Engine emission standards: Meet the non-road stage II emission standards and reduce environmental pollution.
- Hydraulic system: Adopts an open circuit design and combines advanced buffering technology to reduce switching shock and reduce system heat.

Portable concrete mixer pump with diesel engine plays an important role in various construction projects with their flexibility, high efficiency and strong adaptability. Whether it is for long-distance pumping or insufficient power supply, this type of equipment can provide a reliable solution. With the advancement of technology, these devices will become more intelligent and environmentally friendly in the future, further improving work efficiency and user experience.
