Vacuum pump exhaust valve is not working properly, will naturally greatly affect the degree of vacuum, vacuum pump exhaust valve repair is crucial. Today Xiaobian sorted out vacuum pump exhaust valve repair steps.
1, when dismantling, first pump oil let go part of the oil surface down to below the oil window.
2, open the oil windows, remove the valve (or valve bowl, ball), check whether they are intact, smooth, flexible No, the assembly is solid, suitable, pin hole no.
3, usually the valve should be able to cover the vent very smooth.
4, the large pump valve plate is mostly steel, is compressed by the spring, the valve should be checked for damage, the spring is hard to cause the valve is difficult to beat.
5, oil-resistant rubber valve type is to check whether they are deformed.
Description
ZKG vacuum harrow dryer is new type high-efficiency horizontal vacuum drying equipment. It adopts jacketed structure, and the jacket can be heated by steam, hot water or conduction oil. The jacket transfers the heat to the inner wall of the shell via conduction or radiation. The dried materials are added into the dryer through an opening in the middle of the machine shell. Constant stirring of the revolving harrow causes the materials move back and forth. The surface contacting with the inner wall of the shell constantly updates, resulting in high drying rate and uniform finished products.
Application
ZKG vacuum harrow dryer is designed for drying slurry, pasty, powdery materials, thermosensitive materials requiring low-temperature drying, easily oxidized materials, as well as explosive materials, toxic materials and the materials whose organic solvents should be recovered. This vacuum drying equipment is applied to the pharmaceutical, nourishment, food, chemical and other industries.
Features
1. ZKG vacuum harrow dryer uses large-area interlayer heating, which can obtain large heat-transfer surface and high heat efficiency.
2. This vacuum drying equipment with a stirring device can improve the heating uniformity and smoothly dry slurry and pasty materials.
3. It is easy to operate and clean, which can effectively reduce labor intensity.
4. If this vacuum harrow dryer adopts internal concurrent heating, the heating area will be greatly increased.
