product overview A steam jet vacuum pump is a device that uses water vapor as the pumping medium to obtain vacuum. Steam of a certain pressure is ejected at supersonic speed through a Laval nozzle. Convert pressure energy into velocity energy. At the nozzle outlet, low pressure is formed due to the injection effect of high-speed steam flow. The working steam and the extracted airflow are mixed in the mixing chamber and undergo energy exchange. The mixed airflow is decelerated and pressurized in the diffuser tube. Due to different vacuum requirements from users. Each steam jet vacuum pump can be connected in series with a single stage or multiple stages. The more stages there are, the higher the vacuum degree (lower residual pressure). The relationship between general suction pressure and stage is as follows:
In order to reduce the workload and steam consumption of the first and second stage injectors, an intermediate condenser is installed between them. In order to reduce the exhaust noise of the first stage injector, a silencing condenser is installed after the first stage injector The intermediate condenser and silencing condenser can be divided into direct cooling or indirect cooling types. Direct cooling condenser, also known as hybrid condenser, can be divided into spray type and sieve plate type. Intermodal condenser, also known as tube condenser. Model standard
application 1PSQ series: Suitable for pneumatic conveying, exhaust gas (tail gas) recovery (capture), vacuum evaporation, hydrocracking, catalytic reforming. 2PSQ series: suitable for chemical fiber dehydration, oil dehydration, vacuum concentration and evaporation of inorganic salts, alkaline solutions and other compounds. 3PSQ series: suitable for glycerol distillation, oil distillation, oil decolorization, slice drying, vacuum defoaming, monomer recovery, concentration crystallization, vacuum impregnation, vacuum rehydration, etc.

Concentrated crystallization 4PSQ series four stage steam jet vacuum pump Technical Parameter speak bright 1. The minimum allowable working steam pressure is 0.3MPa (absolute pressure). Please specify this when placing an order so that we can configure the nozzle according to the actual working steam pressure of the user. 2. The illustrated condenser is a hybrid type, and we can customize a tubular condenser according to user requirements. Application scenarios 1. Fatty acid distillation 2. Chemical monomer recovery |
