Product Description:

SZ Series Liquid Ring Type Vacuum Pump

Application:

    SZ series liquid ring type vacuum pump and compressor is used to suction or compress air and other gas that is non-corrosive, unsolvable in water and with no solid powder, so that vacuum and pressure can be obtained in the sealed container. However, small amount of liquid is allowed in the suctioned gas. The pump is widely used in several sectors such as mechanical, petrochemical, pharmaceutical, food, sugar making and electronic industry.

     Since the air compression is operated under the same temperature, it won′t easily lead to any danger, when the pump is suctioning or compressing any flammable or explosive gas. Therefore, the pump is widely used.

Technical parameters:



Note:


1. When the vacuum percentage range is 40% to 90%, or the pressure range is 0.05Mpa to 0.15Mpa, the gas suction and drainage will be subject to the amount of the supplied water amount and the crevice between the impeller and the side cover. If the flux is rather small, and the adjustment is not accurate enough, the gas suction and drainage tends to be smaller.
2. The value in the table is obtained under the following condition: ① water temperature is 15℃ ② air temperature is 20℃ ③ relative humidity of the gas is 70% ④ air pressure is 0.1013Mpa
3. The performance difference in the table will not exceed 5%

Q:What's the difference between a double suction pump and a single suction pump?
The difference between a single suction pump and a double suction pump is that the double suction pump has two intake ports, while the single suction has only one intake.
Q:Domestic pump does not use water, or turn, I do not know why?
The motor should be kept working, may be the motor switch problem, idling motor pump long time will certainly be bad, ha ha, the solution is to find a water pump maintenance master to work safety first!
Q:What is the reason that the water supply of pump is getting smaller?
1., first look at the external situation, to see whether the water pump is running, the water level is not normal, the water inlet has nothing blocked.2., exclude the external situation, or small water, the pump itself may leak, it will also make water smaller
Q:What is the influence of the speed of the pump motor on the pump?
The question is very general,In general, high speed motors are used in 2 stages, 2900 revolutions per secondLow speed motor with 4 stage, 1450 revolutions per secondYou can probably generalize to thisWith the flow, head, run the pump speed type low noise will be reduced but the service life of the motor (relatively high speed), but the speed of price ratio low speed expensive (motor level 4 level 2 line than for more than copper)For example, it seems that the reason why turtles live longer is that their heart rate is slow.
Q:4--6 inch deep well pump head? How much per hour out of water?.
General agricultural pump 4-6 inches of lift at about 20 meters, the economic output of water is 140-200 cubic meters per hour
Q:How to identify the motor series of pumps
You can also use the motor speed divided by 50, equal to the motor series.
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
1, frequency conversion water pump is based on ordinary water pump. The so-called common pump means without any automatic control device of the pump, only the pump head and the motor and a base. The power supply is switched on (default: 220/50Hz or domestic power single-phase three-phase 380V/50Hz) run off, stop. Ordinary pumps do not refer to a particular type of pump, can be centrifugal pumps, pipe pumps, vortex pumps, multi-stage pumps and other pumps commonly used.2, the variable frequency pump, is supplemented by a one-way valve, pressure tank, inverter, constant pressure water supply controller, sensor, valve or electrical components in general based on the composition of water pump with automatic function, and automatic constant pressure frequency conversion water supply device. The input power of frequency conversion water pump can be single phase 220V/50Hz or three-phase 380V/50Hz, but the motor of frequency conversion water pump is usually three-phase. The incoming line is a single-phase 220V variable frequency water pump. The motor is a three-phase 220V motor, the input line is three-phase 380V, and the pump motor is three-phase 380V.Two, the differenceAccording to the definition above, the difference between variable frequency water pump and ordinary water pump is obvious. The main differences: first, the frequency pump has automatic function and constant pressure; ordinary water pump does not; second, variable frequency water pump is a unit, the price is much more expensive than the ordinary water pump.
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
Q:How many lift pumps should be used for 100 meters tall buildings?
Specific to calculate pipeline loss in order to know.. According to my experience, feeling that life would be 130 meters -140 meters to 110 meters can fire if the premise is the roof of a pump group
