What is the purpose of running the bottle washing machine empty before it officially starts working

A laboratory bottle washing machine is a device used for cleaning laboratory utensils such as glass bottles and plastic bottles. According to different working principles, laboratory bottle washing machines can be divided into two categories: high-pressure bottle washing machines and ultrasonic bottle washing machines. The high-pressure bottle washing machine is composed of a stainless steel water pump, a high-pressure nozzle, an electrical box, etc. It adopts high-pressure backwash spraying, and the pollutants on the bottle wall can be timely separated and discharged into the water tank, achieving the purpose of cleaning. Ultrasonic bottle washing machine can generate ultrasonic waves, which radiate forward in the cleaning solution with alternating density, causing the liquid to flow and producing tens of thousands of tiny bubbles; The impact of these bubbles can quickly cause pollutants on the bottle wall to fall off and be removed.
Below, we will introduce the operating procedures of the laboratory bottle washing machine to you:
1. Preparation before using the laboratory bottle washing machine
(1) Check whether the electrical switches, instrument indications, and transmission of the laboratory bottle washing machine are normal;
(2) Check if the bottle shifting wheel clutch is in the normal position. If it is in neutral position, please adjust it properly;
(3) Turn on the power switch of the laboratory bottle washing machine, turn on the speed control switch, and the frequency converter operation panel will display the set frequency on the fluorescent screen. At this time, press the RUN button to start the frequency converter working, and the motor speed will gradually reach the set value. Stop pressing the STOP key;
(4) First, let the bottle washing machine run empty for 2 minutes, check whether the equipment and mechanical transmission structure are normal, and whether the operating sound is normal. Production can only proceed after it is normal;
2. Driving the laboratory bottle washing machine
First, open the inlet valve to fill the storage tank with water, open the saltwater free valve, open the injection water valve, spray normally, turn on the water pump switch to fill the cleaning tank with water, adjust the inlet water to maintain a certain water level in the tank (it is strictly prohibited to open the ultrasonic valve without reaching the water level), and open the air valve. After the water level in the tank reaches the specified level, turn on the ultrasonic switch and the ultrasonic cleaning machine enters the bottle washing state.
(1) The operator puts the penicillin bottle into the bottle tray, turns on the speed control switch, and sets the speed to 10-26Hz (100-400 bottles/min 7mL). Press the RUN button to start production.
(2) When there is a stuck bottle situation, first press the STOP button to stop the car, check the stuck bottle area, clean the broken bottles in a timely manner, adjust the bottle wheel, and then start production.
(3) Pull the penicillin bottle into the bottle wheel and track on the bottle sorting turntable, and it is strictly prohibited to pour the bottle into it.
3. Precautions for using laboratory bottle washing machines
(1) It is strictly prohibited to turn on ultrasonic waves below the water level.
(2) After the production is completed, it is necessary to turn off the ultrasonic wave first and then drain the water.
(3) If the bottle washing machine does not work, please have professional maintenance personnel repair it.
(4) If you want to adjust the production volume, please set the required operating frequency according to the frequency converter manual.
(5) It is strictly prohibited to pour bottles into the track.
Operators should strictly follow the operating procedures of the laboratory bottle washing machine to achieve good operating conditions, in order to achieve ideal cleaning efficiency and effectiveness
