The working efficiency of oil filter is closely related to oil pump

When the oil filter works, the role of the oil pump is very huge. It can be said that a good oil pump can provide better oil filter efficiency. In this paper, Chongqing Tongrui oil filter manufacturer summarizes many years of production customer feedback experience, summarizes the selection of oil pump for you.

Determination of oil pump type: the commonly used oil pump can be divided into gear pump, vane pump plunger pump according to the structure. Gear pump is used in low-pressure system is sensitive to oil pollution; vane pump has uniform output flow, small pulsation low noise, but its oil absorption characteristics are good sensitive to oil pollution; plunger pump is easy to get high-precision coordination, small leakage high volumetric efficiency, is often used in high-pressure system together with vane pump, it is also sensitive to oil pollution.

Therefore, gear pump is often used as inlet outlet pump for transformer oil vacuum filter, ordinary hydraulic lubricating oil vacuum filter turbine oil turbine oil filter.

Among them, gear pump is commonly divided into KCB gear pump YCB gear pump. The internal gear of KCB gear pump is of involute helical structure. The gear has high hardness strength after heat treatment, is installed in the replaceable shaft sleeve together with the shaft. The lubrication of all parts in the pump is achieved automatically by using the output medium when the pump is working. The pump has a reasonable design of oil drain oil return groove, which is the minimum torque force of the gear in the work, so the bearing load is small, the wear is small, the pump efficiency is high. KCB gear pump advantage is that the price is moderate, so that customers can easily accept. But the disadvantage is that the wear between the straight teeth is very strong, the noise is high, the service life is shorter. It is usually used as consumables in some working conditions.

YCB circular arc gear pump with double circular arc sinusoidal curve compound tooth profile, has won major scientific technological achievements projects, won the third prize of science technology progress award of the State Education Commission. The circular arc gear is in continuous contact between the two meshing tooth profiles, so the phenomenon of oil trapping will occur. The vibration, noise bearing load increase of the involute gear pump caused by oil trapping are completely solved. The gear is made of double arc sine curve. Compared with involute gear, its most outstanding advantage is that there is no relative sliding of tooth profile surface in the process of gear meshing, so the tooth surface has no wear, stable operation, no liquid phenomenon, low noise, long life high efficiency. The pump has got rid of the shackles of traditional design, which makes gear pump enter a new field in design, production use. YCB circular arc gear pump is characterized by low noise, high pressure good energy saving effect. The cost of YCB arc gear pump is higher than that of KCB gear pump, but considering the performance of the whole oil filter, the service life is longer the price is higher.

The advantages of screw pump used in oil filter are: smooth operation, stable flow, low noise, no vortex pulsation, no shear, it can adapt very low to very high viscosity (- 20 ℃ ~ + 150 ℃), good self-priming ability. However, the disadvantage is that the friction between stator rotor is large, which requires large torque. The efficiency is low, the shaft absorption power is usually 1kW, the manufacturer will provide 3KW even larger motor; the stator sealing parts of the pump are consumables; the style is long thin, requiring large installation space. Conventional oil filter generally does use this type, only when the whole machine configuration requires special pump configuration, in order to match improve the performance of the whole machine, this oil pump will be used.

When selecting the working flow rate of the oil filter oil pump, it should be noted that the flow rate of the oil pump must be greater than the large flow rate when the system is working. Because it is necessary to consider the loss of oil flow caused by the change of pressure resistance at the inlet outlet of the oil filter. Oil filter plays an important role in our production. However, in the actual operation process, we must purchase the corresponding products according to our own needs. Otherwise, it will have a great impact on our use. Oil filter is an environmental protection energy-saving product. Only when it is properly selected will it bring great efficiency to your oil filtration purification oil recycling.
