万源How to adjust the capacity of liquid filling machine?

Liquid filling machine is a kind of equipment used to fill liquid substances into containers, and its capacity adjustment is a very important step. According to the different models and working principles of the liquid filling machine, the method of adjusting the capacity is also different. The following will take the common gravity liquid filling machine as an example to introduce the capacity adjustment method of the liquid filling machine.

Shanghai liquid filling machine is according to the gravity of the material from the storage tank and injected into the container through the filling nozzle. Therefore, to adjust the capacity of the liquid filling machine, it is necessary to adjust the flow control device, which mainly includes adjusting the opening and closing time of the filling volume and adjusting the flow rate.

1. Adjust the opening and closing time of filling volume

The liquid filling machine generally uses a timer or PLC control system to control the opening and closing time of the filling amount. Adjusting the opening and closing time can change the length of time of each filling, so as to achieve the adjustment of capacity.

First, you need to open the control system and find the parameter Settings related to filling volume control. Adjust the timer or PLC parameters to the required opening and closing time according to the equipment instruction manual or experience.

It can also be adjusted by test irrigation, first conducting several test irrigation on the equipment, and then judging whether adjustment is needed by observing the volume and time of test irrigation. If the amount of filling is too large, it is necessary to shorten the opening and closing time; On the contrary, it is necessary to extend the opening and closing time. Try again and again until the desired capacity is reached.

2. Adjust the flow rate

The adjustment of the flow rate is achieved by adjusting the valve of the filling machine, and there are generally two ways: manually adjusting the valve and using the governor.

Manual valve adjustment is a common way to adjust the flow rate of the liquid filling machine by manually rotating the valve. Open the control system of the liquid filling machine, find the parameters corresponding to the flow rate controller, and gradually adjust the opening degree of the valve according to the need, generally rotating the valve counterclockwise to increase the flow rate, and rotating clockwise to reduce the flow rate. Based on the results of the trial irrigation, determine whether further adjustments are needed until the desired flow rate and volume are achieved.

The filling machine using the governor can adjust the flow rate by controlling the speed of the motor. The specific method needs to be operated according to the equipment manual, mainly by adjusting the frequency or voltage of the motor to control the speed. Through the way of trial irrigation, the parameters of the motor are gradually adjusted according to the actual demand until the expected flow rate and capacity are reached.

It should be noted that the following points should be noted when adjusting the capacity:

1. The adjustment must be made when the equipment is shut down, not when the equipment is running.

2. Exercise caution when adjusting the capacity. If the speed is too fast or too large, the device may be damaged or a large number of waste products may be generated.

3. After the adjustment, test irrigation should be conducted to observe whether it meets the requirements. If any problem is found, it should be corrected in time.

The above is the general method of adjusting the capacity of the liquid filling machine, and the specific operation needs to be carried out according to the equipment model and manual. The adjustment of liquid filling machine capacity is a more complex process, which needs to be adjusted according to the actual situation. Only careful operation and continuous attempts can achieve the ideal filling effect and capacity requirements.
