Question:

Water ring vacuum pump shaft seal is not dripping normal?

Water ring vacuum pump shaft seal is not dripping normal? What's the cause? How can I drip water?

Answer:

Mechanical seal: is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The elastic loading mechanism and the auxiliary seal are the mechanical seals of metallic corrugated tubes, which we call metal bellows seals. Mechanical seal with less leakage (basically no water drop) and long life, etc., so the world's mechanical seal is the most important way of shaft sealing in these equipment. The mechanical seal is also called the seal, in the relevant national standard is defined as: "by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or magnetic) device and the role of the coordination of auxiliary seals to keep up with the relative sliding to prevent fluid leakage."
Packing seal, also known as packing packing seal, commonly known as packing seal. Packing seal is a sealing structure for the oldest, in ancient China, the water lifting machinery, is to use the method of filling yarn to block the leakage of the steam engine, the world's first is the seal form. In nineteenth Century, the production and development of oil and gas extraction technology made new developments in the sealing materials. By twentieth Century, because of its relatively simple structure and inexpensive price, the packing seal was favored by many industrial departments for its wide range of sources. Packing sealing requirements are dripping, at about 6-8 drops per minute. Packing drip has two functions: cooling and lubrication. In the operation of the unit, adjust the gland gland, you can adjust the packing seal leakage.
Water ring vacuum pump shaft seal can not be normal water drop. If the pump uses a mechanical seal, it does not drip.There are two main forms of shaft seal: one is traditional and the other is free of packing; the other is mechanical seal.
