Screw press and hydraulic oil press which better?Prepared to buy oil press, will mention this problem!Oil vendors would forrest analysis should be from two aspects to identify good and bad, that is the good design, the manufacture is good.palm oil mill
First of all, the oil vendors would forrest to make a brief introduction of screw press and hydraulic oil press press theory of two kinds of models:
Pressure acting on the oil part is passed to the oil and the other part is used to make the fuel produces deformation.So we have to start from the above two points.
First, try to minimize the deformation of the pressure caused by the oil, the method is based on oil pretreatment due to lower oil resistance to deformation.However, lower oil resistance to deformation ability too much, slag in the process of exploitation.
Second, we should appropriately increase is passed to the oil pressure, which is to appropriately increase on oil pressure.air product
Squeeze is expected to shed more oil capillary number, capillary diameter is larger, the better.Which would require oil pressing speed and pressure to a certain proportion, prevent capillary smaller less.
Capillary flow oil as short as possible.That is cake the thinner the better.Squeeze the time within a certain range as long as possible.The lower the pressure oil viscosity, the better.This is when you squeeze, oil and machinery must have certain temperature;However, high temperature will lower the quality of the oil and oil cake.
In the identification of screw press:the refining process
1, identify size: screw press should be expressed in vats screw diameter of bore diameter or its size.However, some models of hydraulic oil vendors would not explain vats screw diameter bore or;There are also some hydraulic oil vendors would in small charge is big.
2, identification to squeeze the other functions: can generally includes machine heating, can filter oil, can the simple refining (4 -- 5 to take off the oil...
