In the process of using the vacuum packaging machine will encounter the following common problems: 1. Low vacuum 2. Noise 3. Vacuum pump injection 4. Vacuum pump leakage 5. Vacuum pump soot 6. No heating 7. Heating is not Stop 8. Sealing is not smooth, tight or not sealed steel box deformation adjustment steel box 9. While heating, while not heating 10. Pump does not pump vacuum 11. Cover does not work, etc.
1. Pump oil pollution, too little or too lean cleaning vacuum pump, replace the new vacuum pump oil; pumping time is too short to extend the pumping time; suction filter plug cleaning or replacement exhaust filter; leak, close after emptying Power supply, check the solenoid valve, pipe fittings, vacuum pump suction valve and the surrounding area of ​​the studio gasket for leaks.
2. The vacuum pump coupling wears or breaks; the exhaust filter is clogged or the installation position is not correct. Clean or replace the exhaust filter and install it correctly. If there is a leak, check the solenoid valve for leaks and remove it. Vacuum packaging machine (1 sheet)
3, the suction valve O-ring off the vacuum tube on the pump nozzle, remove the suction nozzle, remove the pressure spring and suction valve, gently stretch the O-ring several times, re-embedded in the groove, and then Can be installed; rotary vane wear replacement rotary vane.
4. The oil return valve is blocked to remove the oil return valve and cleaned (see the instructions for details). After the oil window is loosened and drained, remove the oil window and wrap the raw material tape or thin plastic film.
5, suction filter plugged or polluted cleaning or replacement of exhaust filter; pump oil pollution replaces new oil; return valve block plug cleaning return valve
6. Heat bar burned to replace the heating bar; heating time relay burned out (two lights on at the same time, bright, OMRON lamp color is yellow), replace the time relay; replace the heater wire with the heating wire, and install firmly; control the heating temperature band Poor contact of the switch, repair or replacement; control of the heated AC contactor does not reset the repair (using a gas flow to blow off foreign objects) or replacement; the bad replacement of the heating transformer
7. When the heating time relay is in poor contact or burnout, adjust the time relay to contact or replace the socket; control the heating AC contactor to not reset or replace.
8, heating time and heating temperature is not adjusted to adjust to the right; there are attachments on the heated cloth with a nail to gently scrape attachments; pressure solenoid valve does not act to clean or replace the solenoid valve; airbag damage replacement airbag; pressure tube damage Repair or replace; no bleed cooling time relay is bad (in the electrical box) replacement time relay; deflate valve circuit is open circuit to find and connect; deflate valve is stuck or burned to remove cleaning or replacement
9. Non-heating side of the packaging bag and the heating device short-circuit (usually short circuit with the brazing sheet) Adjust the position of the brazing sheet, or rest the bag pouches
10. The studio does not cover the studio tightly; the motor is reversed (be careful not to change the ground wire, the color line is the ground wire); the insurance disconnect (indicator light is on) replace the same specifications insurance
11, no power to check whether the power supply; trip switch does not act to adjust the trip switch paddle; insurance off (lights on the indicator) Replace the same specifications insurance frequently burn insurance short circuit to find and rule out; motor reversal time is too long any two-phase power cord Replacement installation (except ground); oil viscosity is too high Clean the pump and replace the oil inside the fuse box

Geosynthetic Clay Liner (GCL)
It is composed of 3 levels. The upper level and the lower level are Woven Geotextile and non woven textile. The middle level is bentonite grains, which are carefully selected from Liu Fangzi crude and filled in between the two levels after special processing.
Product characters:
1. Environment friendly
GCL is made of natural raw materials of sodium-bentonite. It is raw and natural materials,;aging and corrosion seldom happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material.
2. Permanent waterproof, excellent performance
Natural sodium bentonite was formed billions of years ago.
Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform to high density septum under hydro pressure. When The thickness is 3mm, the permeability is below a×10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention performance is evident.
3. Easy to construct
Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap point. When water comes, GCL would be overlapped automatically. It is so far the only material that starts the waterproof effect by water in the world. It is not necessary to take additional examination when the construction is completed. The repair works are easy in case of waterproof defects. Among the existing waterproof materials, GCL`s construction period is the shortest and its operation is the easiest. It has an eminent effect on shortening the construction period as well as saving the cost.
4. Strong Self-Restore Capacity
The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.
