V. Structure and Principle
The complete machine is composed of vacuum cover, vacuum work chamber, body,
electric section and vacuum system. The vacuum cover is equipped with a set of heating
devices wherein the heating element is the nickel-chromium band installed on the heat
sealing support. There is absolute insulation between the heating element and the vacuum
chamber. The heat sealing support clings to the airbag. Prior to heat sealing, the air bag
is in the state of low vacuum, during the course of heat sealing, the airbag connects to air
gives rise to pressure difference via action of the heat-sealing electromagnetic valve YV1,
which makes airbag volume become big and press down the ironing head (nickel-chromium
band) for sealing and heating simultaneously, while the heating temperature and heating
time can be adjusted. The vacuum work chamber is equipped with the heat pressing and
sealing device to complete the packing coupled with the heat sealing support.
The power supply of this machine is three-phase four-wire system, inputting 380V,
50HZ AC power or 220V, 50HZ AC power in the form of center line. The vacuum machine
motor: voltage: 220V/380V AC, 2X0.75KW power, 2800 rev./min. The heating system
is of pressure regulating type, i.e. the elementary voltage of the heat sealing transformer
AC 220V/380V, and secondary voltage thereof has three gears that can be adjusted via the
shape on the panel. The optional voltages: 28V, 32V and 36V. The heat sealing temperature
2
can be changed by changing the elementary voltage, while the heat sealing time can be
adjusted via the keys on the panel.
As for the single-chamber vacuum packing machine, the heat-sealing electromagnetic
YV1 and air-out electromagnetic YV2 form the vacuum system to be serve as an
actuating mechanism. As for the double-chamber vacuum packing machine, heatsealing electromagnetic YV1 and air-out electromagnetic YV2 form the vacuum
system. As for the desk-top/single-chamber gas-filled vacuum packing machine, the
heat sealing electromagnetic YV1, air-bag suction electromagnetic valve YV3, gasfilled electromagnetic valve YV4, air-out electromagnetic valve YV2 form the vacuum
system. As for the double-chamber (plate) gas-filled vacuum packing machine, the heat
sealing electromagnetic valve YV1, air-bag suction electromagnetic valve YV3, gas-filled
electromagnetic valve YV4, YV5, air-out electromagnetic valve YV2 form the vacuum
system.
Vacuum machine startup is to evacuate the vacuum chamber. When the preset vacuum
degree is achieved, the vacuum machine can stop working, and the whole control program
is transferred to the next program, and this machine is provided with the single-stage rotary
vacuum machine (for the technical performance of the pump, please see the Instruction

the Packing List; whether the screw on each part of this machine is loosened or not; whether the
organic glass cover of the single-chamber vacuum machine moves up and down flexibly or not;
whether the vacuum cover of the double-chamber (plate) vacuum packing machine moves left
and right flexibly or not.
2. All moving parts, oil holes, and oil nozzles shall be properly lubricated. According to the
specifications of the vacuum pump instruction, the appropriate amount of vacuum oil is filled into
the vacuum. And the vacuum oil filled via the oil inlet shall be 3/4 of oil window height, and the
oil level during the pump running shall be not less than 1/4 of oil window height. The maximum
oil quantity shall not exceed 3/4 of oil window height.
3. Adjustment
a. Adjustment of Vacuum Degree of Vacuum Chamber
In light of the need of the packed articles, select the best suction time to obtain the
appropriate vacuum degree. The longer the suction time is, the higher the vacuum degree is.
b. Adjustment of heat sealing temperature and heat sealing time
According to the different materials of the packing bag and the different packed articles,
optimally select the heat sealing temperature (1-3 gears adjustable) and the heat sealing time on
the panel (0-9.9 sec.) to obtain the optimal sealing strength. Adjust the temperature low to high to
make the desired appearance and the strength available for sealing
VIII. Operating Procedures
1. Switch on: turn on the power switch, i.e. the power indicator is on. Set the air suction time,
heat sealing time, cooling time, and heat sealing temperature.
2. Pack the articles into the packing bag (compound-plastic bag or compound-aluminum foil
bag), put the packing bag in any vacuum chamber, lift the batten, put the bag mouth evenly under
the heat sealing support for arrangement, and then put down the batten.
3. Screw down the vacuum cover, i.e. the suction (vacuum) indicator on the panel is on. The
vacuum machine starts suction to enable the machine cover to be automatically pulled. The pump
down time can be adjusted appropriately according to the packing requirements.
4. When the suction reaches the set time (i.e. required vacuum degree), the suction will come
to an end, and the indicator will be off and the heat sealing indicator will be on, in this case, the
electromagnetic valve will act, thus the sealing procedure will begin. There is a heat sealing time
button and a temperature adjusting button on the panel. Note that the time and temperature shall
be adjusted according to the specifications of the packing bag.
5. When the set heat sealing time is reached, the heat sealing indicator will be off to end the
heat sealing and complete the cooling procedure. In this case, the air-out electromagnetic valve
will act, the air will enter the vacuum chamber, the vacuum cover will be lifted automatically, and
thus the progress of the vacuum gas packing will come to an end, and the next packing cycle will
get ready.
6. In case of the gas-filled vacuum packing machine, it is necessary to fill the required
gas (nitrogen gas is selected in general) for heat sealing after finishing evacuating the vacuum
chamber, then the residual gas (nitrogen) in the vacuum chamber must be extracted, finally, the
air-out electromagnetic vale acts and the packing progress ends.

IX. Troubleshooting
1. Failure of creation of vacuum or low degree of vacuum.
a. Check whether the vacuum machine reverses or not, i.e. whether the rotation direction
coincides with the motor arrow. If not, the phase must be adjusted on a timely basis.
b. The vacuum cover seal ring and the working chamber surface are not sealed very well
during the course of a machine, so it is necessary to exert a slight pressure on the vacuum cover,
to enable the vacuum cover and the working chamber to be completed sealed.
c. Check whether the sensitive switch contact of the single-chamber vacuum packing
machine is sound or not, and whether the travel switch of the double-chamber vacuum packing
machine is in place, if not, it is necessary to adjust the position of the sensitive switch or the travel
switch.
d. In case of leakage arising from improperly closing the vent valve, check whether the vent
valve electromagnetic valve, valve core (rubber) is aged or polluted, or whether the valve is off
centering, in case o f the aforesaid conditions, the maintenance or replacement must be made on
a timely basis.
e. Check whether all parts of the pipeline are leaked or loosened.
2. Poor heat sealing quality
a.Check whether the packing bag is clean. Do avoid dirt at the sealing.
b.Check whether the nickel-chromium band works normally or not, and whether short circuit
and open circuit occurs.
3. Main-board faults
a. Keep the main-board circuit inside the machine clean and dry. It is not allowed to have the
metallic foreign matters on the surface to avoid short circuit inside the main board or disorder
program.
b. In case of jump action when creation of vacuum or heat sealing is not conducted, the seat
leg of the corresponding switch can not be plugged firmly or the press key is damaged.
c. In case of the missing of digital display board or the failure of the action indication, it
means that the seat leg of the digital display board is loosened or the digital display is partially
damaged.
d.In case the high/mid/low heat sealing doesn’t work, it means that the pins of corresponding
high/mid/low relay are loosened or the relays are damaged.
X. Repair and Maintenance
1. Please read the Instruction carefully to have a mastery of adjustment and utilization
methods before use.
2. Make regular maintenance and oil charge for the vacuum pump in accordance with
the specification of the vacuum pump. Note that reversion is not allowed to prevent the pump
damage and the pump reverse, and reversed spraying of vacuum oil on the vacuum system inside
the pump.
3. Do ensure the oil level shall be 1/2-3/4 of oil window height during the course of vacuum
pump running. The oil level and conditions of oil pollution shall be checked on a regular basis
(once a week advisable). In case vacuum oil is darkened, emulsified, and thickened arising from
oil pollution, the polluted oil shall be replaced on a timely basis, and clean the vacuum pump
before filling up with new oil.
