This is an interesting question that is not easy to answer because it is very difficult to find absolute reasons for it. Before entering into the process of accountability and scrutiny, however, it is necessary to note that the points made in this memo are by no means absolute and definitive.
This is not due to lack of knowledge or lack of knowledge, but different manufacturers may choose diesel water pump motors for heavy and large applications for various reasons.
However, the cause of this problem cannot be stated with certainty, but we will examine the most probable and common causes in the following note. In this note, you will encounter the following sections to get the answer:
A fundamental look at this question apart from just pump motors.
Why do trucks and trailers have diesel engines?
Large pump motors require high power.
Large pump motors must have more resistance.
Providing cheap fuel is a key issue.
A fundamental look at this question apart from just the pump motors
Note that before we look at this issue of pump motors, let's take a closer look at the question, what are the advantages and features of diesel engines? By answering this question, we can answer the main question of the text more easily:
Diesel engines are highly efficient and their productivity is surprisingly high. Due to their structure and fuel consumption, these engines are more efficient than gasoline engines, and this is perhaps the main advantage of this type of engine over others.
Diesel engines are durable. The two factors of higher compression ratio and higher heat during operation have led to the use of better raw materials in the construction of this type of engine, and in the design, an attempt is made to consider the thickness and diameter of the blocks at a high level.
This makes these engines more durable than their main competitor and consequently longer.
More torque is an important achievement for diesel engines. Because these types of engines produce more energy than gasoline models, their torque is also higher under equal conditions. Although it is not possible to achieve high speeds with diesel engines, it is possible to create high torque and more power.
Cheap fuel consumption is an important advantage for a diesel engine. Considering the approved price of gasoline and diesel, you will find that diesel fuel is a much better choice that, along with a lower price, with a smaller volume, can produce the same amount of power as needed.
Now, despite knowing the strengths of the diesel engine, it is better to examine the answer to the question of why large pump motors make diesel. But there is one interesting point before you make a case study that you may not have noticed. Carefully at this point, you will understand the correctness of the causes.
Why do trucks and trailers have diesel engines?
Certainly, after facing this question, you have realized what our purpose in designing it is. Even with the products of the automotive industry, you will find that diesel engines are primarily designed for heavy work and require high power. Therefore, the fact that large pump motors use this type of motor is not a coincidence at all, and the long experience in the field of automotive products has strong reasons in this regard.
Large pump motors require high power
The need for high power confirms several points. First of all, this means that you need a lot of efficiency in this type of pump motor, because due to some design limitations in terms of engine volume, you have to get more energy from the minimum amount of engine volume and fuel consumption, and this in Diesel engine possible.
Large pump motors need to receive this high power from the minimum fuel limit, which should be diesel, and the minimum engine volume, which is a diesel engine.
This is a strong and indisputable reason for using a diesel pump motor in heavy applications. Of course, this is only part of the story.
Another issue that is very important in large pump motors is the need for high torque; this is what the diesel engine has as its strength. The need for high torque in large pump motors inadvertently leads us to the diesel pump motor.
Large pump motors must have more resistance
Obviously, in the face of more labor, the pump motor must be more prepared to withstand pressure and accept hardness. This is possible in the diesel pump engine.
Looking at the reasons for the superiority of diesel engines, you will find that for various reasons mentioned earlier, these types of engines have more resistance and, despite being designed for harsher conditions and higher temperatures, are able to provide better performance under double pressure.
Do not forget that a large pump motor is used to pump water in more difficult conditions, and it is natural to put more pressure on it.
Undoubtedly, doing heavier and more difficult tasks requires more fuel consumption, and it is undeniable that providing gasoline fuel on a large scale is very costly.
If you need 500 liters of gasoline per month to use your heavy pump motor, this means that you have to spend 1 million and 500 thousand Tomans with the free rate of gasoline, but you can provide the same amount of energy with 100 liters of diesel, and This is while the cost price will be only 30 thousand Tomans! This price difference, as you saw in our hypothetical example, is very large and noticeable in a way that cannot be ignored.
Note that the numbers for monthly consumption are hypothetical, but the price of free gasoline, 3 thousand Tomans per liter and 300 liters per liter of free diesel, is defined according to reality.
