Fuel consumption of concrete pump is a main performance and an important indicator that investors may easily ignore when purchasing. Fuel consumption of concrete pump are one of the biggest expenses in daily use.
So what is the fuel consumption of concrete pump? How can we reduce fuel consumption and save cost? Let’s find out the answer together!
Concrete pumps are divided into two main types according to pumping method and transporting way. One is concrete line pump trailer, the other is concrete pump truck. Let’s take a look at the fuel consumption of these two different types of concrete pumps separately.
Here, the so-called fuel consumption refers to the fuel consumption of the main diesel engine equipped in concrete pumps during operation.
Fuel Consumption of Concrete Pump Trailer
Due to small size and no traction power requirements, the selections of diesel engines in concrete pump trailers and pump trucks are quite different. Taking LUTON concrete pump as an example, the world-class Chinese brand Weichai engine is mostly used as the main power unit.
According to different concrete production rates, Weichai engines configured in the current hot-selling concrete drag pumps (30 -180 cubic meters) range from 52kW to 199kW.
The specific minimum fuel consumption rate is about 192g/kw·h on average, that is to say, when the engine is working at full power, we can calculate it as follows:
Minimum fuel consumption per hour = 192 × diesel engine power. So, we can get this table as follow:
|Concrete Pump Trailer||Minimum Fuel Consumption Per Hour|
Taking theoretical output capacity and the actual deviation 0.8 into account, to output 1m3 of concrete, the diesel fuel consumption of a trailer pump is probably:
|Concrete Pump Trailer||Minimum Fuel Consumption Per Cubic Meter|
Note: The above data are calculated under ideal conditions and rated output capacities, for reference only and cannot represent actual values.
Fuel Consumption of Concrete Pump Truck
Like concrete pump trailer, fuel consumption of concrete pump truck is affected by Just like concrete drag pumps, the fuel consumption of boom pumps is also related to factors such as pumping output capacity and pumping height.
Meanwhile, the power system of the concrete pump truck is different from the drag pump system, which is divided into a traction engine and a pumping system power engine. Under normal circumstances, the fuel consumption of the boom pump truck is about 0.5L/m3-0.9L/m3. (Note: Data hereis for reference only and do not represent actual values.)
Factors Affecting Fuel Consumption of Concrete Pump And Solutions
Fuel consumption of concrete pump is the biggest expense in the daily work of concrete pump trucks. To reduce pumping costs, we must consider how to make the pump truck more fuel efficient. For concrete pump trucks, what are the ways to save fuel?
Too low tire pressure can cause tire deformation, resulting in more friction, which will lead to more oil consumption.
Meanwhile, trucks drive on different roads. For different road conditions, the tire pressure requirements are different. Normal tire pressure is suitable for normal paved roads, but on rough roads such as sandy mud, it is necessary to reduce the tire pressure appropriately to avoid truck trapping.
2.Keep The Economical Speed
The so-called economical speed refers to the speed at which the vehicle consumes the least fuel during the driving process. The economical speed is a range within which fuel consumption is relatively low. For pump trucks, the most fuel-efficient speed is 40-60km/h.
While driving, it is also important to choose a gear that matches the speed of the vehicle. Usually, when driving at high speed, the higher the gear, the more fuel-efficient it is.
In the process of pumping concrete, a high gear with a small transmission ratio should be selected. At this time, the thermal efficiency of the engine is the highest, which means more oil can be saved.
3.Chassis Engine Output
It is recommended to select the chassis engine with larger output power when purchasing. Using a low-power chassis to pull a large car not only cannot reduce fuel consumption, but also accelerates engine wear and reduces the service life of the engine.
4.Weight Loss For Pump Trucks
Under the conditions of the same chassis engine, the lighter the weight of the upper part of the pump truck, the more fuel-efficient.
5.High and Low Pressure Pumping
Engines consume fuel to convert chemical energy into kinetic energy. To obtain higher kinetic energy and stronger pumping pressure, it is necessary to consume more fuel. So when to use high-pressure pumping and when to use low-pressure pump have become the key to saving fuel consumption.
When pumping concrete horizontally or downwardly, it is necessary to overcome the gravity effect of concrete, so it is more suitable to use low-pressure pumping. When pumping concrete vertically upwards, high pressure is required to complete the pumping. Therefore, specific analysis of specific scenarios and flexible switching of high and low pressure pumping methods can help reduce fuel consumption.
6.Displacement Size Control
As pump pressure, displacement of concrete pump also affects the fuel consumption. The hydraulic oil output per unit time with a large displacement is larger, so higher the engine speed is, and higher the fuel consumption is.
Therefore, the selection of the displacement also requires the operator to make a reasonable judgement based on the accumulation of experience in daily work.
7.Operation Experience of Different Drivers and Operators
The fuel consumption of the pump truck is also closely related to the driver’s driving habits and operating experience. The same vehicle, operated by an experienced and skilled pump operator will save more fuel than a novice operator.
The fuel consumption of a concrete pump is related to many factors. And in the actual use process, different equipment brands, configurations and working conditions all affect the fuel consumption more or less.
