Circulating water vacuum pump, also known as water ring vacuum pump, is a kind of vacuum pump
.
The vacuum it can obtain is 2000-4000 Pa, and the tandem atmospheric ejector can reach 270-670 Pa
.
The water ring pump can also be used as a compressor, called a water ring compressor, which is a low-pressure compressor with a pressure range of 1-2X105 Pa gauge
.
The pump is based on the multi-purpose vacuum pump for circulating water.
According to the characteristics of the small laboratory area, the transparent anti-corrosion water tank, anti-corrosion shell and stainless steel shell are improved to reduce the volume and improve the volume.
It has the characteristics of beautiful shape and so on.
It has four tables and four heads for air extraction and is equipped with ice filling holes
.
How to use: 1.
Preparation
.
Put the circulating water multi-purpose vacuum pump flat on the workbench.
When using it, open the upper cover of the water tank and inject clean cold water (you can also add water through the water hose).
When the water surface is about to rise to the height of the overflow nozzle behind the water tank, stop adding water and repeat.
No more water can be added when the machine is turned
on.
Change the water at least once a week.
If the water quality is seriously polluted and the usage rate is high, the water replacement time must be shortened to keep the water in the water tank clean
.
2.
Vacuum work
.
Tightly sleeve the suction sleeve of the equipment that needs to be vacuumed on the suction nozzle of the machine, turn off the cycle switch, turn on the power supply, and turn on the power switch to start the vacuuming operation.
The degree of vacuum can be observed
.
3.
When the multi-purpose vacuum pump for circulating water needs to work continuously for a long time, the water temperature in the water tank will rise, which will affect the vacuum degree.
By controlling the flow of tap water, the water temperature in the water tank can be kept from rising and the vacuum degree can be stabilized
.
4.
When it is necessary to provide cooling circulating water for the reaction device, on the basis of the operation in the previous item 3, connect the water inlet and outlet pipes of the device to be cooled to the circulating water outlet and inlet nozzles at the rear of the machine respectively.
, turn the circulating water switch to the ON position, and the circulating cooling water supply can be realized
