What is Hydraulic? How to choose the right heat exchanger?

The hydraulic station, also known as the hydraulic pump station, is an independent hydraulic device. It supplies oil according to the requirements of the driving device (host) and controls the direction, pressure, and flow of the oil flow.

It is suitable for various hydraulic machinery where the host and the hydraulic device are separable Bottoms, the motor drives the oil pump to rotate, the pump sucks oil from the oil tank and then pumps the oil to convert the mechanical energy into pressure energy of the hydraulic oil.

Common problems of installing water cooler:

  • The water pipe is too long. From the inlet to the outlet of the workshop, the water temperature has risen to the same level as the ambient temperature of the workshop when the water flows, and the effect is greatly reduced. Especially for the machines working on the second and third floors, the pipes are longer and the pipe layout is more inconvenient. This is one of the reasons why customers have changed water coolers to air coolers in recent years.

  • In a hydraulic station with a large oil tank storage capacity, if the water cooler is more than 1 cubic meter, if the copper pipe bursts, the entire tank of oil will be scrapped, and the maintenance cost is too high for general users to accept. This is also a factor to be considered when choosing a cooler for hydraulic station systems.

​The problems faced by these water coolers can be solved by air coolers.

They do not require long pipes, re-disassembly, no risk of oil-water mixing, power saving, environmental protection, and so on. Although there are many advantages, it still has its shortcomings. Its pressure resistance is not as good as water cooling, and the installation is more particular.

Jiaerda can provide you with an excellent air cooler device to assist your hydraulic station system. If an air cooler is suitable, use an air cooler. If it is not suitable, Jiaerda can also provide you with oil Refrigerators, industrial chillers and other equipment are also high-end and powerful refrigeration equipment, widely used in industrial production and processing, we will design a reasonable refrigeration plan for you and provide a series of services.

FAQ

Q: What is the purpose of the heat exchanger?
A: The hydraulic system uses a heat exchanger to control the oil temperature within the optimal range, thereby controlling the viscosity within the optimal range. In this range, the fluid has the best combination of characteristics useful to hydraulic system components. Although some hydraulic presses can operate without external cooling, such as small, low-load or load-sensing systems, most hydraulic presses require a device to keep the oil within an ideal temperature range.

Q: What does the heat exchanger do?
A: It will use fluids such as water or air to transfer heat to and from the hydraulic fluid. But the nature of heat transfer by heat exchangers can vary greatly. Liquid-to-air and liquid-to-liquid are the two main types of heat exchangers, which can use air and water, respectively, to remove heat from the hydraulic system.

Q: What are the characteristics of shell and tube heat exchanger?
A: This heat exchanger installs a series of copper tubes into a larger shell. The copper tube can be a single bent tube or many small tubes that span the two plates on both sides of the shell. Both methods will use a perforated shell, which itself is just a metal bucket with water flowing from one end to the other. The water or coolant passes through the copper pipe to transfer heat from the hydraulic oil to the cooling medium, and then discharges it into the wastewater or returns to the coolant system.
