Where is the hydraulic oil radiator? The best way to dissipate heat from hydraulic oil

Hydraulic oil radiators are mainly used in the circuit of the hydraulic system, and different equipment is placed in different positions. When working, the high-temperature oil in the hydraulic system flows through the hydraulic oil cooling device, and the forced cold air is efficiently exchanged in the heat exchanger, so that the oil temperature is reduced to the working temperature to ensure that the main engine can continue to operate normally, so that the work can be carried out smoothly.

Hydraulic oil radiators are used in construction machinery that uses hydraulic oil as the force transmission medium, such as: excavators, concrete pumps, fine mortar pumps, boom pumps, truck-mounted pumps, pile drivers, trenchers, rotary drilling rigs, pavers, trenchless equipment, air compressors, road rollers, etc.

Many domestic excavators are water tanks and hydraulic oil radiators are integrated, the landlord only needs to see that there is no water outlet that is the hydraulic oil radiator, I specialize in this, small excavators generally do not have intercoolers, but excavator hydraulic oil radiators are a must.

However, the excavator has been designed to meet the requirements of the radiator when it leaves the factory, if you have to add it, you need to consider the impact of its pressure drop on the system and whether the space can be accommodated.

If there is a phenomenon of high temperature of the hydraulic system in the system, there are generally two points: first, there is a continuous overflow in the system (such as the main relief valve is opened with a small opening for a long time, and the main pump has a small flow of internal leakage); Second, the radiator does not give full play to its heat dissipation efficiency (such as excessive dust or debris blockage in the radiator air duct, and the failure of the radiator bypass valve is always open).

Generally next to the water tank, you look carefully.

The landlord's may be air-cooled.

For hydraulic fluids in mechanical equipment such as hydraulic presses, effective heat dissipation is required to maintain their normal operating temperature and performance. Here are a few commonly used methods of hydraulic oil heat dissipation:1

External heat dissipation: Install the hydraulic oil tank in a well-ventilated location and dissipate heat through external equipment such as radiators and heat exchangers. This method is suitable for situations where the operating environment of the hydraulic system is high and a large amount of heat dissipation is required.

2.Internal heat dissipation: A radiator or heat sink is set inside the hydraulic oil tank to dissipate heat through fluid flow or natural convection.

This method is suitable for situations where the internal space of the hydraulic system is small and an external radiator cannot be installed. 3.Water cooling and heat dissipation:

The water-cooled radiator is used to exchange heat between the hydraulic oil in the hydraulic oil tank and the circulating water to achieve the effect of heat dissipation. This method is suitable for situations where hydraulic combustion and lapping systems require long-term high-density work. 4.

Gas cooling: By setting up a liquid-gas heat exchanger in the oil return pipeline of the hydraulic system, the high-temperature oil return and cooled gas are used for heat exchange to achieve the effect of heat dissipation. This method is suitable for situations where the operating environment of the hydraulic system is at a high temperature, but the water is stressed.

It is necessary to choose the appropriate heat dissipation method according to the specific situation of the hydraulic system, and ensure that the temperature of the hydraulic oil is within the normal range of the main shed.

The best way to dissipate heat from the hydraulic oil is to reduce the temperature of the hydraulic oil by using a radiator or cooler. These devices can cool the hydraulic oil to a suitable temperature range to ensure the proper operation of the hydraulic system. In addition, the heat dissipation of the hydraulic system can be improved by increasing the flow of hydraulic oil or by using efficient hydraulic oil.

Summary. Hello, I am glad to answer for you The best way to dissipate hydraulic oil heat is as follows: 1. The oil through the cooler is a part of the oil return of the system, and the amount of heat dissipation flow depends on the size of the throttle hole (1) corresponds to a certain temperature and a certain flow of oil return, the smaller the throttle hole, the larger the heat dissipation flow, and vice versa.

2) The diameter of the throttle hole is not determined by a single factor and must be considered comprehensively. Relevant factors are: the power loss of the system, the target control range of the oil temperature, the constraint of the size of the return pressure of the system, etc.

3) The final determination of the orifice size should be a statistical result based on experiments and ambient temperature.

There are several ways to dissipate heat from the hydraulic system:1Air cooling:

Arrange fans or air ducts around the hydraulic system, and use natural convection or forced convection to dissipate the oil and heat in the radiator or oil tank into the air. This method is relatively simple, but it is relatively ineffective and easily affected by factors such as ambient temperature and humidity. 2.

Water heat dissipation: A water cooler is set around the hydraulic system to dissipate the heat inside the system through the cooling effect of water. This method is better than air cooling, but it requires the construction of a special water cooling system, and the cost is high.

3.Oil heat dissipation: Set up a radiator or oil cooler and other devices inside the hydraulic system, use the fluid inside the radiator or oil cooler to cool the hydraulic oil, transfer the heat generated to the outside of the cooler, and dissipate it through natural or forced convection.

This method is more effective and easy to implement, but it needs to occupy a certain amount of space in the hydraulic system. 4.Gas-liquid heat dissipation:

A gas-liquid heat exchanger is set inside the hydraulic system to exchange oil and gas inside the system, and the heat is dissipated through cold and heat exchange. This method works well and saves space, but it requires expertise and equipment to make it happen. To sum up, according to the actual situation and requirements of the hydraulic system, the best effect can be achieved by choosing the appropriate heat dissipation method.

The hydraulic oil does not dissipate heat after the simple and high balance radiator, what is going on, 1. The periphery of the radiator is dirty, resulting in poor air intake, which reduces the amount of heat dissipation. 2. The lack of thermal insulation around the radiator leads to repeated circulation of hot air. 3. The return check valve is damaged, resulting in the hydraulic oil being unable to enter the heat dissipation gear for cooling, and directly returning to the oil tank.

Hello dear, no. The reasons are as follows: (Hydraulic Flush 1) The radiator of the hydraulic oil should be installed under the hydraulic oil tank, so that the hydraulic oil flows from the radiator to the oil tank, not from the oil tank to the radiator; (2) Air bubbles may form above the hydraulic oil tank, affecting the normal flow of hydraulic oil; (3) The upper part of the hydraulic pump may be subjected to excessive temperature, which will affect the normal operation of the hydraulic pump; (4) The radiator of the hydraulic oil is installed above the hydraulic pump and the hydraulic oil tank, which will affect the cooling of the hydraulic oil, thereby affecting the efficiency and reliability of the system.

Hello pro is very happy for you: the hydraulic oil radiator can be installed above the hydraulic pump and hydraulic oil tank, but you need to pay attention to the following points:1

The radiator should be installed in such a way that the radiator can fully dissipate heat and will not affect the normal operation of the equipment. 2.The installation position should be protected from external force impact or other possible damage.

3.The circulation of hydraulic oil should be in line with the working principle to avoid problems such as poor or too fast flow of hydraulic oil caused by improper installation position. 4.

There should be enough space around the radiator to dissipate heat and avoid obstruction or other factors that impede heat dissipation. In short, when the radiator of the hydraulic oil is installed above the hydraulic pump and the hydraulic oil tank, it is necessary to pay attention to the reasonable installation position to ensure the normal operation of the spine equipment and the full heat dissipation effect. If you need more professional advice, it is recommended to consult the relevant hydraulic equipment professional.

Hope it can help you dear.

The hydraulic oil and silver fuel temperature is high, adjust the system pressure according to the standard, and timely overhaul the worn hydraulic components for heat dissipation. There are many reasons why the temperature of hydraulic oil is too high, such as poor heat dissipation, improper selection of oil grades, excessive pressure adjustment, and wear of components, so it is necessary to adopt cooling measures in time, clean the radiator regularly, and choose hydraulic oil reasonably.
