Gear pump is widely used in petroleum, chemical, shipbuilding, electric power, grain and oil, food, medical, building materials, metallurgy and national defense research and other industries. Mainly used in a variety of mechanical equipment in the lubrication system for conveying lubricants, gear pumps for conveying viscosity 10. E (75C.St) below, the temperature of 300 ℃ or less lubricity of the oil. Gear pump noise, or strong vibration, in particular, the following aspects in addition to the problem: 1. Suction pipe or filter plugging 2. Gear pump suction pipe into the liquid surface shallow 3. Pipe into the air 4. Gear Pump discharge pipe resistance is too large 5 gear bearing or side plate serious wear 6. Gear pump rotation part of the interference 7. The viscosity of the inhaled liquid is too large 8. Gear pump suction height exceeds the rated weight can be handled by the gear pump vibration noise Problems: 1. Gear pump to eliminate the dirt on the filter 2. The suction pipe should be deep into the liquid pool around 3. Gear pump check the joints, to seal 4. Check the drain pipe and the valve is clogged 5. Gear pump removed Cleaning and repair defects or replacement 6. Remove the inspection and troubleshooting 7. Gear pump viscosity measurement and treatment according to Article VI of the first phenomenon in Article VI 8. Increase the level of inhalation
Microscope Slides And Cover Slips
1. The glass slide is used to put the sample to be tested, and the cover glass is covered on the sample to be tested.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
6. The cover glass is square, the slide glass is rectangular, and the width is longer than the side of the cover glass.
