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 sell are supporting equipment for rotary evaporation, glass reactors, short-path distillation and other products. They are specifically divided into: circulating water vacuum pumps, rotary Disc vacuum pumps and diaphragm vacuum pumps.
A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space.
Laboratory vacuum pumps, as the name implies, are vacuum pumps used in laboratories. These 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 pumps, rotary vane vacuum pumps, and diaphragm vacuum pumps. Below we introduce the detailed information of these three vacuum pumps in detail.
Circulating Water Vacuum Pump
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, and is equipped with two vacuum gauges. Circulating water vacuum pumps can provide vacuum conditions for chemical laboratories and provide circulating cooling water to reaction devices. Circulating water vacuum pumps are widely used in evaporation, distillation, crystallization, filtration decompression, sublimation and other operations. Circulating water vacuum pumps are divided into vertical circulating water vacuum pumps and desktop circulating water vacuum pumps, which are suitable for supporting rotary evaporators and have the characteristics of small size, light weight and beautiful appearance. Circulating water vacuum pump is specially equipped with rotary evaporator, double-layer glass reactor, vacuum drying oven, vacuum filter, filter bottle, rotary thin film evaporator, multifunctional reactor, vacuum thin film concentrator and other products, which are indispensable in the laboratory One of the ideal products.
Working Principle of Circulating Water Vacuum Pump:
The working medium of the circulating water absorber vacuum pump is water, which belongs to the centrifugal mechanical pump. The impeller rotor is installed in the cylindrical pump casing. Its blades are forward curved. when the impeller rotates. Under the action of centrifugal force, water forms a water ring that swirls along the pump casing. The water ring runs relative to the blades. The volume of the space between two adjacent blades changes periodically. When the blade rotates from the upper right to the lower. The water between every two leaves is pushed outward. Make the volume of this space gradually increase from small to large. It reaches the maximum at the bottom. Then the gas is sucked in from the axial suction port. And when the blade rotates from the bottom to the top left. The water moves relative to the axis. The space between the two leaves gradually changed from large to small. The inhaled gas is gradually compressed and finally discharged through the exhaust port. With the steady rotation of the impeller. Each volume wheel changes repeatedly. Make the suction and exhaust process continue.
Model of Circulating Water Vacuum Pump:
ZZKD Machineryhas been focusing on R&D and production of circulating water vacuum pumps for many years. Circulating water vacuum pumps are one of our main products. After many upgrades, the models and types of circulating water vacuum pumps have become more and more perfect.
Circulating water vacuum pumps are divided into vertical circulating water vacuum pumps and desktop circulating water vacuum pumps. There is one type of circulating water vacuum pump: SHZ-C.

Diaphragm Vacuum Pump
The use of laboratory diaphragm vacuum pumps is becoming more and more widespread, and most laboratory equipment will be equipped with vacuum pumps, because the vacuum pump is not a single device, it can be used in conjunction with other instruments. Such as vacuum filtration, microbial detection, waste liquid extraction, rotary evaporator, vacuum drying oven, freeze dryer and other equipment. Vacuum pumps are auxiliary equipment for every laboratory. Different instruments and equipment have different requirements for vacuum pumps.
Working Principle of Diaphragm Vacuum Pump:
Diaphragm vacuum pumps are commonly used equipment in laboratories and are often used in conjunction with rotary evaporators. The simple working principle of the diaphragm vacuum pump is: the circular motion of the motor makes the diaphragm inside the pump reciprocate through the mechanical device, thereby compressing and stretching the air in the pump cavity to form a vacuum, and creating a pressure difference between the suction port and the external atmospheric pressure , Under the action of pressure difference, the gas is sucked into the pump chamber and then discharged from the exhaust port.
Diaphragm Vacuum Pump Model:
ZZKD Machineryhas been focusing on R&D and production of diaphragm vacuum pumps for many years. Diaphragm vacuum pumps are one of our main products. After many upgrades, the models and types of diaphragm vacuum pumps have become more and more perfect, and their functions have become more and more perfect. Diaphragm vacuum pumps are available in two series: DP series and MPC series.
Diaphragm Vacuum Pump Features:
·Space saving, easy to carry and move
·Simple and convenient operation
·The diaphragm vacuum pump can be used with a solvent recovery device, and the solvent can be recovered twice during the exhaust process.
·According to different purposes, the exhaust speed selection switch design is set.
·Lower noise, can be directly connected to the 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
The 2XZ rotary vane vacuum pump is the basic equipment for obtaining vacuum. The rotary vane vacuum pump uses the piston in the pump chamber to rotate to suck, compress and discharge the gas. The rotary vane vacuum pump can be started at one time with the atmosphere or any vacuum degree. It can act alone or as a backing pump and pre-pump for various high vacuum systems.
Working Principle of Rotary Vane Vacuum Pump:
The rotary vane vacuum pump has a two-stage structure. Its working performance consists of two parts: a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment. During operation, a large amount of gas in the container will be sucked and discharged. When the equipment obtains vacuum, the exhaust valve of the high-pressure stage will be closed, and the gas inhaled by the high-pressure stage will be transferred to the second stage, and then sucked and discharged by the second stage, so that the vacuum equipment can obtain a certain vacuum.
Models of Rotary Vane Vacuum Pumps:
ZZKD Machineryhas been focusing on R&D and production of rotary vane vacuum pumps for many years. Rotary vane vacuum pumps are one of our main products. After many upgrades, the models and types of rotary vane vacuum pumps have become more and more functional Complete. There are currently six models of rotary vane vacuum pumps on sale: 2XZ-8B, 2XZ-15B, 2XZ-0.5, 2XZ-1, 2XZ-2, 2XZ-4.
Features of Rotary Vane Vacuum Pump:
·Fast pumping speed, small size, light weight, low noise, easy maintenance.
·Reliable dust-proof device.
·There is a compound screw with an air release valve and an oil inlet hole, which is fast and labor-saving, and improves the working efficiency of the rotary vane vacuum pump.
Rotary vane vacuum pumps are suitable for scientific research and production in metallurgy, chemical industry, light industry, petroleum, medical treatment, electric vacuum, semiconductor, food, textile and other scientific research institutions, colleges and universities, industrial and mining enterprises. However, rotary vane vacuum pumps are not suitable for pumping gases that are corrosive to metals, chemically react to pump oil, contain particles of dust, or contain explosive gases that contain too much oxygen.
