Rotary vane vacuum pump used in the industries of crystal _

rotary vane vacuum pump application in the crystal is what? Evaporation and cooling crystallization is supersaturated liquid to form crystal. These crystal easy to carry, storage and sales. For such applications, rotary vane vacuum pump is to control all the pressure within the scope of the evaporation/choice of cooling rate, and by lowering the boiling point of liquid to reduce production costs.

1. Enrichment: distillation, emissions, radioactive waste, black liquor, sugar, sugar beet

2. Recovery gold-plated materials and photographic solution

3. Production of ammonium nitrate, sodium hydroxide, such as

4, crystal sugar, salt, health care ball, aniline, urea, calcium sulphate, potassium carbonate, amino acid, penicillin and antibiotics

first of all, small make up to show you what is crystal and crystal.

crystal is one of a large number of micro material unit ( Atoms, ions, molecules, etc. ) In an orderly way to arrange the structure. Therefore, from the size of the structural unit arrange study rules and crystal morphology. Crystal, a kind of amorphous material into the process of crystal. Among them, the amorphous atomic arrangement is not has a long range order material, its melting point is not fixed, in metastable, and a tendency to spontaneously into a steady state. Crystal is internal particles (in 3 d space Atoms, molecules, ions) 。 Repeat with something of a long range order (on a regular basis Is greater than the regular arrangement of micron grade) 。 Filling and/or material transfer, when the milk and cream body injection pipe and so on, have to discharge the air inside. This can be done through filling machine. Through rotary vane vacuum pumps will shift the liquid tank, and then through the compressor, so as to realize the transfer of the liquid.

rotary vane vacuum pump the correct application before applying for, you should first read product manual carefully, and check after opening the package transportation quality. Collect the spare parts and technical documents, remove the exhaust baffle. Press the request equipment, wiring, and then turn. Receiving water water pump.

in order to avoid because of the oil and oil change oil, first open mouth, pump will pump according to the regulation memory oil into fuel tank). At the same time, check the oil level, oil level should be higher than the mimeograph center, but don't move the oily be soiled, more should be released.

is used to distinguish between steering auxiliary method. Pour sheath to a port on the pump. If it is pumping, it will be inhaled. It is forward, boasting and reverse. In square up sound is normal, and abnormal sound was reversed.

if pumping mouth is equipped with pneumatic solenoid valve, shall be installed horizontally and pump at the same time.

when the relative humidity is higher or pump such as water vapour in the gas can be condensed steam, gas ballast valve should be used.

according to the directions it is recommended to use vacuum pump oil. Note ester vacuum pump oil should not be mixed with mineral oil type vacuum pump oil and other oil. Must be clean before use ester vacuum water pump oil replacement.

according to the compact mercury vacuum gauge to check the limit pressure of the pump. All pressure gauge measurement and adjustment should be paid attention to the matching alignment and standby is adjusted. Suggestions in regulating ball valve installation between pump and the pump being measured. If the valve closed when not in use, you can extend the application of time adjustment.
