Vacuum pump refers to the equipment that extracts air from the equipment to provide a vacuum environment. There are many types of vacuum pumps. The vacuum pumps we supply are supporting equipment for extraction equipment,such as : rotary evaporator, glass reactor, short path distillation and other products. They are divided into: circulating water vacuum pump, rotary vane vacuum pump and diaphragm vacuum pump,they are also commonly used equipment in laboratory.
Laboratory vacuum pump working principle
Vacuum pump refers to a device that uses mechanical, physical, and chemical methods to pump a container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space.Laboratory vacuum pumps, as the name suggests, are vacuum pumps used in laboratories. These types of pumps are often small in size but have good performance, and are especially suitable for use in laboratories with experimental instruments. Our company has three types of vacuum pumps suitable for use in laboratories with experimental instruments. These three types of vacuum pumps are: circulating water vacuum pump, rotary vane vacuum pump, and diaphragm vacuum pump. Below we introduce the details of these three vacuum pumps in details.
Circulating water vacuum pump for extraction
The circulating water vacuum pump is a centrifugal mechanical pump. The working medium is water. The body adopts double taps and can be used alone or in parallel. It is equipped with two vacuum gauges. The circulating water vacuum pump can supply a vacuum state in a chemical laboratory and change the cooling water in the reactor. Circulating water vacuum pump is widely used in evaporation, distillation, crystallization, filtration and decompression, sublimation and other operations. The circulating water vacuum pump is divided into a vertical circulating water vacuum pump and a desktop circulating water vacuum pump. It is suitable for a rotary evaporator and has the characteristics of small size, light weight and beautiful appearance. Circulating water vacuum pump is specially equipped with rotary evaporator, double glass reactor, vacuum drying box, vacuum filter, filter bottle, rotary thin film evaporator, multifunctional reactor, vacuum thin film concentrator and other products, which are indispensable for laboratories. One of the ideal products.
Circulating water vacuum pump for extraction features
·Multi-meter multi-tap design, can be used individually or in parallel
The pump head is made of corrosion-resistant material
The core motor part is stainless steel motor shaft
There is a check valve on the pumping line to prevent accidental shutdown during vacuuming
·Stable and reliable work, low noise.
Diaphragm vacuum pump for extraction
Laboratory diaphragm vacuum pumps are being used more and more, and most laboratory equipment includes vacuum pumps. The vacuum pump is not a single device that can be used with other equipment. Vacuum filtration, microbial detection, sewage extraction, rotary evaporation, vacuum drying oven, vacuum drying and other equipment. Pumps are a useful tool in all labs. Different tools and equipment have different requirements for vacuum pumps.
Diaphragm vacuum pumps are sold in two series: DP series and MPC series
DP series: DP-01-20
MPC series; MPC201 T, MPC301 Z, MPC601 T, MPC1201 T.
Diaphragm vacuum pump for extraction features
Save space, easy to carry and move
·Simple and convenient operation
·The diaphragm vacuum pump can be equipped with a solvent recovery device, and the solvent can be recovered twice during the exhaust process.
·The design of the exhaust speed selector switch is set according to different purposes
·Lower noise, can be directly connected to vacuum controller
Diaphragm vacuum pumps are suitable for the treatment of corrosive gases in chemical, pharmaceutical, petrochemical and other industries, such as suction filtration, vacuum distillation, rotary evaporation, vacuum concentration, centrifugal concentration, solid phase extraction, etc.
Rotary vane vacuum pump for extraction
2XZ type rotary vane vacuum pump is the basic equipment for obtaining vacuum. Rotary vane vacuum pump: It uses the piston in the pump chamber to make a rotary motion to inhale, compress and discharge the gas. The rotary vane vacuum pump can be started once under the atmosphere or any vacuum degree. It can be used alone or as the backing pump and pre-pumping pump of various high vacuum systems.
There are six types of rotary vane vacuum pumps: 2XZ-8B, 2XZ-15B, 2XZ-0.5, 2XZ-1, 2XZ-2, 2XZ-4.
Advantages of rotary vane vacuum pumps
·High-speed pump, small size, light weight, low noise, easy maintenance.
·Reliable dustproof device
·It is equipped with a compound screw with an air release valve and an oil inlet hole, which is quick and labor-saving, and improves the working efficiency of the rotary vane vacuum pump.
Rotary vane vacuum pump is suitable for scientific research and production in metallurgy, chemical industry, light industry, petroleum, medical, electric vacuum, semiconductor, food, textile and other scientific research institutions, colleges and universities, industrial and mining enterprises. However, the rotary vane vacuum pump is not suitable for pumping out the gas that is corrosive to metal, chemically reacts with pump oil, contains particulate dust, and has high oxygen content and explosive gas.
