Diaphragm filter presses differ in principle from other filter presses
principle:
The principle of the diaphragm filter press is the same as that of all the filter presses. It is also designed by the device itself, so that the pressure difference is formed on both sides of the diaphragm in the filter chamber of the filter press. This force is provided for the liquid in the mixed liquid to pass through the diaphragm. The original power, so that the liquid is dialysis from the diaphragm, the solid is blocked by the diaphragm on the diaphragm, in the filter chamber, accumulate into a filter cake. When the filter cake reaches the design range, the filter press will stop feeding, which is the principle of the first half of the diaphragm.
Diaphragm filter presses have processes that are not available in other filter presses when the diaphragm press stops feeding. The device automatically introduces gas (air or inert gas) or liquid (water, oil) into the filter chamber, so that the filter plate or membrane expands into the space of the filter cake, and further presses the filter cake in the filter chamber to further dry and dry. The water in the filter cake, such as capillary water and structural water, is removed.
The filter plate of the diaphragm filter has a filter plate that is different from other filter press equipment. Structurally, the filter plate of the diaphragm filter press adopts the upper feeding, the design of the empty outlet below, and the concave bevel design, which appropriately increases the length and density of the protruding points on the filter plate, so that effective The contact of the filter with the filter cloth is increased (and the effective filtration area is increased), and the filter cake inventory is increased, which reduces the pressure of the filter cake on the bottom of the filter plate.
the difference:
The biggest difference between the diaphragm filter press and other filter press equipment is the structure of the filter chamber. The solid medium of the diaphragm filter press is the diaphragm of the rubber diaphragm type and the PP integral diaphragm, while the medium of the ordinary filter press is The filter cloth woven with fiber has a clear difference in the material of the medium. The diaphragm filter press can also perform a secondary expansion pressure to further dry filter the filter cake.
Blood System:
Blood system is also called circulatory system.
For the treatment of diseases of the circulatory system:
According to the American Heart Association, cardiovascular disease is the leading cause of death in the United States. Because of its vastness and critical nature, it is one of the systems of the body most prone to disease.

One of the most common diseases of the circulatory system is arteriosclerosis, in which the fatty deposits in the arteries causes the walls to stiffen and thicken the walls. According to the Mayo Clinic, the causes are a buildup of fat, cholesterol and other material in the artery walls. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke.
Stroke involves blockage of the blood vessels to the brain and is another major condition of the circulatory system, according to Mitchell Weinberg of the North Shore-LIJ Health System. [Risk factors include smoking, diabetes and high cholesterol," he noted.
Another circulatory disease, hypertension - commonly called high blood pressure - causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure, the NLM noted.
An aortic aneurysm occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions, according to Weinberg.
Peripheral arterial disease (also known as PAD) typically involves areas of narrowing or blockage within an artery, according to Jay Radhakrishnan, an interventional radiologist in Houston, Texas. In addition, chronic venous insufficiency (also known as CVI) involves areas reflux (or backward flow) within the superficial veins of the lower extremities.
PAD is diagnosed with noninvasive testing including ultrasound, CT scan, and/or MRI. Ultrasound is the least expensive of these methods, but also gives the least amount of detail, as CT and MRI show a much higher degree of anatomic detail when identifying areas of narrowing/blockage within an artery. CVI is diagnosed with ultrasound as the venous reflux can be measured accurately by ultrasound, which ultimately guides treatment.
