2. Vacuuming operation, close the suction sleeve of the equipment that needs to be vacuumed to the suction nozzle of the machine, check that the circulating water switch should be closed, turn on the power, turn on the power switch, and start vacuuming. The vacuum gauge corresponding to the suction nozzle can observe the degree of vacuum.
3. When the machine needs to work continuously for a long time, the water temperature in the water tank will rise, affecting the degree of vacuum. At this time, the water discharge hose and the water source (tap water) can be connected, the overflow nozzle is used as a drainage outlet, and the tap water is properly controlled. The flow rate can keep the water temperature in the water tank from rising and the vacuum is stable.
4. When it is necessary to provide cooling circulating water for the reaction device, the water inlet and outlet pipes of the device to be cooled are respectively connected to the circulating water outlet nozzle and the water inlet nozzle at the rear of the machine, and the circulating water switch is turned ON. A circular cooling water supply is available.
The circulating water vacuum pump is easy to use and has been debugged at the factory. As long as the instructions are used, it is not necessary to install and debug.
Circulating water vacuum pump purchase
Circulating water vacuum pump parameters:
A new type of vacuum (exhaust) pump that uses circulating water as a working fluid to generate negative pressure by fluid jet technology, used as vacuum reflux, vacuum drying, and especially for the production of gas with a higher boiling point. gas.
Circulating water vacuum pumps are widely used in biochemistry, medicine, pharmaceutical, food, environmental protection, universities, research, and laboratories.
Circulating water vacuum pump purchase
Circulating water vacuum pumps are divided into two categories: bench top and vertical, with a small number of pumping heads on the table, generally up to 2-4, with less water in the pump, generally 15L; up to ten vertical exhaust heads. The pump can hold 30L of water.
The difference in materials leads to a large price difference. At present, the common anti-corrosion engineering plastic shell is widely used in the market. The cost is very low, the price is cheap, but it is easy to age, deform and has a short service life. The shell of Shanghai Zhixin products is injection molded with high quality plastic. Into, anti-corrosion and impact, there will be no aging, deformation phenomenon; Shanghai Zhixin products will be returned free of charge for one year due to quality problems.
The pump head is the heart of the product. It is generally divided into anti-corrosion plastic and stainless steel. Since the supporting instruments often contain corrosive solvents, they will enter the pump when vacuuming. Therefore, anti-corrosion is the key to selecting circulating water pumps, and rarely contacts corrosive solvents. Ordinary plastic pump head can be used, often in contact with corrosive solvents or solvents. Corrosion is very strong. Stainless steel pump head must be used. The pump head of Shanghai Zhixin circulating water pump is made of high-quality anti-corrosion plastic or high-quality stainless steel mold to ensure product quality.
In addition: the key component that determines the quality and price of the product is the motor. The quality of the motor directly determines the degree of vacuum and product life. The pump motor of Shanghai Zhixin is customized for special processing to ensure product quality. It also has the confidence to guarantee a one-year free return. committed to.
Use of circulating water vacuum pump 1. When using for the first time, open the top cover of the water tank to inject clean cold water (can also add water through the drain hose). When the water surface is about to rise to the height below the overflow nozzle of the water tank, stop adding. Repeat the power to stop adding water. . However, the water is replaced once a week for the longest time. If the water pollution is serious and the usage rate is high, the time for replacing the water can be shortened. The ultimate goal is to keep the water in the water tank clean.
After-sales commitment:
Shanghai Zhixin Experimental Instrument Technology Co., Ltd. promises that the circulating water vacuum pump will have quality problems within one year and will be returned unconditionally. The customer will send it back to: No. 699, Zhenchen Road, Baoshan City Industrial Park, Baoshan District, Shanghai, China. We confirm the non-human use problem. Will replace you with a new circulating water pump (within one year), if it is caused by human error, we will repair it for you free of charge (more than one year to collect the maintenance fee), to solve the after-sales worry at any time.
