Hannan Hydraulic Station hydraulic system: The hydraulic system in the hydraulic system caused by foam!

Classification:

【Summary】When the hydraulic system of Hannan hydraulic station is working, the foam caused by gear oil seriously harms the dynamic model of the price of small hydraulic station, and is likely to cause volume modulus changes, resulting in cavitation, noise, oil dissolution, water temperature rise, oil deterioration and a series of problems.

When the hydraulic system of Hannan hydraulic station is working, the foam caused by gear oil seriously harms the dynamic model of the price of small hydraulic station, and is likely to cause volume modulus changes, resulting in cavitation, noise, oil dissolution, water temperature rise, oil deterioration and a series of problems.

1 Gear oil itself made of foam plastic

Some of the preservatives in gear oils are chemicals that are easy to cause foam. When the gear oil is working, because of the stirring and transmission system, the finished oil itself will cause more foam.

Gear oil when working, because the operating temperature rises, the load working pressure increases, and the running time increases, it is likely to lead to the oxidation and dissolution of the air of the finished oil itself, resulting in the composition of multiple foam plastics or the destruction of the original anti-foam additives, which will also promote the expansion of gear oil foam plastics.

2 The hydraulic machinery itself will increase the product foam

The infiltration of gas into the finished oil is the key reason that the finished oil causes the foam. In the specific operation, the gas is likely to be mixed into the finished oil in a variety of ways. For example, the connection part of the pipeline is insufficient, the suction pipe of the pump or the pipe seal is leaking, the oil import of the car tank is high, and the refined oil in the car tank is reduced, which all causes the gas to enter the refined oil and cause more foam.

3. Removal of oil foam in the hydraulic system of Hannan hydraulic Station

The way to reduce or remove the product foam from the price of a small hydraulic station is to apply the hydraulic station system with excellent sealing and the gear oil with low foam at the source. Use the following techniques to remove and reduce or remove product foam from the hydraulic station system.

① The most common way to deal with excessive oil foam is to select a suitable anti-foaming agent to be added to the relevant oil to manipulate or remove the foam. Antifoam additives should generally have the following characteristics:

The unit symbol of defrosting is ml/10min, in plain words, defrosting refers to the volume of bubbles left after the liquid has caused bubbles for ten minutes. In terms of mechanical lubricating oil, two kinds of testing methods can be used: wave shaking bottle method and air exchange drum brewing method.

② The defroster equipment connected to the hydraulic station system can remove the foam in the finished oil at work.

When the hydraulic system of Hannan hydraulic station is working, the foam caused by the gear oil will indeed cause a lot of inconvenience to the normal operation of all the small hydraulic station prices.

A brief introduction to the cleaning process of plate heat exchanger?

Plate heat exchanger is a kind of heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the plates through which heat is exchanged. So do you know what the cleaning process is? Let's follow Xiaobian together to simply understand it!

Air cooler manufacturers: installation and separation of air coolers and selection

For proper installation, it is recommended to use hoses, properly install bypass and unload loops, or use independent circulation cooling. The air cooler must be placed in a well-ventilated place, and it is easy to bruise the dirt of the air entering the side, and there must be a space above the radius of the fan blade before and after to facilitate the air circulation and heat exchange effect. In order to protect the air cooler from rupture, when the air cooler is installed in the oil return loop, it is necessary to install a by-pass unloading circuit, which is in parallel with the cooler, and confirm that when the pressure relief encounters convex waves, it can be preferentially open for unloading. Clean the air side, you can use compressed air or hot water, along the direction of the aluminum sheet to clean, please note that the power must be off, and protect the fan coil from water.

Air cooler manufacturer: How to layout the hydraulic system air cooler to make its actual effect best

The air cooler manufacturer is a machine equipment that uses gas as a heat exchanger to carry out heat exchange, and heat is brought according to the gas. The key to the actual effect of heat removal lies in the total heat transfer area and exhaust air volume of its component heat pipe radiator. The same total heat transfer area, the greater the exhaust air volume, the better the actual effect of heat removal. Its installation parts and natural ventilation problems in the whole process of use must be fully considered, then how to layout explosion-proof air cooler can make it give full play to the best practical results?
