Steam-injection vacuum pump
Product description
Steaming-injection vacuum pump forms vacuum in the suction chamber in a way of that a pressured steam passing through Laval nozzle becomes faster and in lower pressure and then enters into the suction chamber to mix with medium, carries the medium moving to the expansion tube with lower speed and higher pressure, and finally into next injector or the atmosphere. Due to the client needs different vacuum degree, each steam-injection vacuum pump can be series-connected with single or multiple-grade injectors. The more the stages of injectors are adopted, the higher the vacuum degree will be obtained (the lower the residual pressure). The relationship of Suction pressure with stages is shown as the follows:

≥14 |
5.3-8 |
0.67-1.33 |
0.133-0.67 | In order to reduce the working load and steam consumption of the first grade and second grade injectors, an intermediate condenser is placed between the first grade and second grade injector.
In order to reduce the emptying noises of the first grade injector, a muffling condenser is placed after the first grade injector.
The intermediate condenser and muffling condenser consists of three types: spraying direct-cooling type, hybrid direct-cooling type and tube indirect cooling type.

1. The permissive minimum steam working pressure is 0.3Mpa (absolute pressure). The customer should make it clear so that our com pany can provide proper nozzle according to required steam working pressure;
2. The sketch on the right shows a hybrid direct-cooling condenser, our company can provide tube still indirect-cooling condenser;
3.This pump can also work without muffling condenser. This pump with muffling condenser can reduce working noises. Application Cases
1.Used for concentrated evaporation of compounds
2.Used for vacuum concentration of non-organic salts and base liquor;
3. Used for grease precipitation and dehydration;
4. Used for processing of phthalic anhydride..2P series grade-2 steam-injection vacuum pump
