Application
1.Get all the rubber pipes and interfaces connected as per the illustration (the pipes need to be sterilized).
2.Turn on the power switch ⑤ on the panel and the power indicator ⑥ will be on. The pump will start working (the pump working can be heard). When the interface ① is pressed, the negative pressure meter ④ shall indicate negative pressure.
3.For adjusting the negative pressure, its necessary to block the interface ① with finger and turn the negative pressure regulating knob ⑧ with negative pressure up when the knob turned counter clockwise, and down when clockwise.
Attention shall be paid to the level of liquid in the vessel during use. When the liquid level is approaching the overflow valve, suction shall suspend till the vessel is emptied and washed clean. Otherwise, the overflow valve will close and the suction will have to stop.
In this apparatus, power supply from electric grid, interior batteries and lighter plug is adopted.
(1) Power from electric grid: put plug ⑨ AC220V power supply into the outlet of AC220V electric grid, and the power indicator ⑥ will be on. Turn on the power switch ⑤ when suction is required. At the same time, the 12V accumulator will be charged; and when the battery is full, the charging indicator ⑦ will be on.
(2) Battery: When a power failure occurred, the control section of the apparatus will switch to power supply from battery automatically. The battery will be able to work for
about 1 hour when it is full. (When the voltage declines, the power indicator will flash. At this time, some other power supply or emergency means shall be considered.) The battery shall be charged after use. Normally, the time for charging is 4~5 hours.
(3) Vehicle cigar lighter: Fitted on the apparatus are plug and wires and socket for connection. Plug the input end of the plug wire into the socket, and the indicator on the plug will be on; the apparatus will start service.
Malfunctions, causes and solutions
| No. | Phenomenon | Causes | Solutions | Remarks |
| 1 | Negative pressure limit≤0.08Mpa | 1.Air leakage at the vessel opening; 2. Regulating valve not tightened or loose; 3.Air leakage at the connection of pipeline | 1.Wash the vessel opening and tighten the vessel block; 2.Tighten the regulating valve; 3. Have the pipelines well connected to prevent air leakage. | 1.Replace the vessel cover if the cover deformed; 2. Replace the suction pipe if the pipe is broken. |
| 2 | Negative pressure≥, the suction force in the pipeline decreased or disappeared | 1.Overflow device closed; 2.Pipeline blocked; 3.Air filter blocked | 1. Loosen the regulating valve, turn off the suction switch; and tighten the valve after there is no pressure in the pipeline; 2. Wash, dredge or replace the rubber pipe; 3. Replace filter | Empty the vessel whenever necessary |
| 3 | Normal power voltage, but power indicator not on and motor doesn’t work | 1. Power supply from electric grid or the plug having inadequate connection; 2. fuse broken | 1. Check and repair the plug; 2. Replace the fuse | |
| 4 | Fuse broken immediately after power connection | 1. Line problem; 2. Pump blocked, electric current increased | 1. Check and repair the line circuits; 2. Check and repair the pump motor | Technical staff required for check and repair (refer to electrical diagram) |
| 5 | Liquid accessing the pump but coming out from the air exhaust opening | Overflow value closed and out of service | Check and repair or replace the overflow device |
