LAWSON dry goods! On the Importance of Maintenance and Safety of Grinding Instruments

Under the condition that multi-sample tissue grinding machine slowly replaces traditional manual grinding machine, the number of times of using grinding machine increases correspondingly. What safety factors should be paid attention to in the process of using multi-sample tissue grinding machine?

Let's talk about the working principle and operation method of LAWSON Loshan DHFSTPRP series multi-product organization grinder.

I. Working Principle of LAWSON Loshan Multi-product Organizational Grinding Machine

Through mechanical transmission, the abrasive beads in the centrifugal tube are driven to move irregularly from left to right or from top to bottom, so that the abrasive beads continuously impact the sample, thus achieving the ideal effect of crushing.

2. LAWSON LOSHAN GRINDING MACHINE OPERATION PROCESS

1. Select the appropriate adapter according to the sample size.

2. Put the sample into the EP tube.

3. Add grinding beads.

4. If the sample is difficult to be treated, it can be frozen with liquid nitrogen.

5. Place EP tube in adapter.

6. Install the adapter into the spindle buckle to prevent loosening and tighten it with the fastening nut.

7. Set the parameters of the grinder and start it.

3. Problems in the operation of LAWSON Luoshan Grinding Machine

1. Adapter, the probability of this problem is relatively small.

2. Put the sample into the EP tube.

This is the first problem we should pay attention to: LAWSON Loshan EP tube. EP tube must be wall thickness, so as to withstand impact. Several air traffic control tests can be done before determining the use of the tube.

3. Grinding beads, as long as this is selected according to the sample. Not too big, too big and easy to break; not too small, too small force is not enough, resulting in inadequate grinding.

4. Liquid nitrogen freezing treatment, this attention to protection, avoid liquid nitrogen frostbite.

5. Place EP tube in adapter. In excessive placement, attention should be paid to balancing. In the process of high frequency oscillation, if the center column moves up and down unevenly, there will be deviation, which will affect the service life of the instrument, and there will be hidden safety hazards in the correct operation and use.

6. Install the adapter into the spindle buckle to prevent loosening and tighten the nut. Be sure to tighten the fastening nut. If not tightened, the adapter will impact up and down, which can easily cause column accidents.

7. Setting the parameters of the grinding instrument. Just pay attention to this. Don't spend too long, such as half an hour or one hour.

As long as we avoid these mistakes, we can protect the grinder and our samples. If you have any doubts during the use, please contact our after-sales staff. Do not disassemble and maintain the machine by yourself!

4. Analysis and troubleshooting of common faults of LAWSON Luoshan grinder

1. Click-start can't start properly.

Please check the induction switch at the open cover for pressure. Set the frequency is too low.

2. After startup, there is a lot of collision noise in the equipment.

Please check whether the bottom transport nut is unloaded. Whether the anti-loosening of the adapter is in a vertical state or not.

3. After power-on, the program displayed on the display screen appears the word "communicating".

Please check if the data line on the back of the display screen is loose.

4. There is unstable jitter in adapter and cover during operation.

This indicates that the nut of the fixed adapter may be worn out and new nuts may be replaced.

5. The power switch light is on and the display screen is not displayed.

It shows that the connector of the display screen of the equipment is loose. Please contact the after-sales personnel for repair.

6. In the process of using, or after a long period of unused, the equipment does not react when confirming the correct connection of the power supply and the correct start-up operation.

Explain that the equipment has started self-protection function in the case of short circuit. It is necessary to contact after-sales personnel to replace the fuse.

7. The spindle of the internal fixing adapter of the instrument has obviously loosened or broken, or the internal fittings of the instrument have malfunction. Please contact our after-sales staff.
