Vacuum pump is our main product. Customers who have purchased vacuum pump in our company know that our after-sales service is very good.
We all know that the vacuum pump is an indispensable equipment for vacuum packaging machine to obtain vacuum, so how do we install it? Today, we introduce how the vacuum pump is installed on the vacuum packaging machine. In general, we use rotary vacuum pump for single room or double room vacuum packaging machine. The pump is small in size and can be directly installed in the vacuum packaging machine, with a circular cushion as the bottom connection. If it is a large number of manufacturers, we will generally configure higher vacuum pump to meet the needs of customers’ efficient production. However, the volume of vacuum pump will increase with the increase of vacuum efficiency. However, the size of the vacuum packaging machine itself is fixed, so it can’t be directly put into the vacuum packaging machine, so this is especially the method of using external vacuum pump for customized equipment.
What is vacuum packaging machine
The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be filled with nitrogen or other mixed gas, and then the sealing process can be completed. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation.
Food vacuum packaging machine vacuum packaging sausage, meat products, biscuits and other food. The packaged food can prevent mildew, guarantee quality and keep fresh, and extend the storage period of the product. Only pressing the vacuum cover can automatically complete vacuumizing and sealing.
The vacuum of this equipment type only needs to press the vacuum cover to automatically complete the process of vacuumizing, sealing, printing, cooling and exhausting according to the procedure. After packaging, the product can prevent oxidation, mildew, moth, damp, guarantee quality, keep fresh and extend the storage period of the product.
Vacuum packaging machine generally has two-phase and three-phase electric equipment. In addition to small vacuum packaging machine and external vacuum packaging machine, in order to ensure the stability of the equipment, most of the vacuum packaging machines are three-phase electric. The following is the wiring method of vacuum packaging machine:
It is necessary to connect the wires correctly in order to start the machine normally. When wiring, pay attention to the power of the switchboard and vacuum pump, and do not exceed the rated range. Select the right switch and fuse according to the rated power and voltage. Before connecting the power to the vacuum machine, open the door on the left side of the machine first. After opening the machine manually, touch the travel switch, open the electrical box, and plug the time relay in again. After finishing the above two steps, connect the power line of the vacuum packaging machine to the power supply, and the power line of the vacuum pump to the motor. After the power supply of the vacuum packaging machine is connected, always remember to test before the official work. Turn on the power switch of the switchboard. At this time, the conveyor belt should move towards the direction of the vacuum chamber. In case of reverse rotation, any two of the three-phase power supplies should be replaced in time. Then start the vacuum pump switch and observe the running direction of the pump. Do not reverse it, otherwise it will cause permanent damage. The correct operation direction is marked on the protective cover. When adjusting, it is also the position of any two wires in the three-phase power supply.
