The allocation of various equipment and parts feeding device, when used in each step of the operation must be coordinated, according to normal operation steps, dosing device can be normal and reasonable, Bonham pump to introduce how to use the right.

One: before the start of the preparation

Dosing device inside and outside surface of 1. new installation should be cleaned, check and clean the oil holes of all, and the circuit is smooth.
The 2. pipeline cleaning, check the pipe is blocked, the metering pump is blocked or pipeline leak.
3. check the connecting parts are not allowed to loose.
4. according to the ambient temperature, the transmission mechanism box should be added to adapt to the environment or other mechanical oil lubricating oil to the oil standard so far.
5. due to rotation of metering pump coupling and mixer impeller to run more than two weeks, check whether the influence of operating obstacles.
6. metering pump safety valve should be adjusted off about 1.25-1.45 times of stress at work, should not be too high or too low.

Two: operation and use

1. before the start of the preparation work, the power supply is switched on, start mixer, mixer to stir clockwise, then start the metering pump.
2. stop work should be performed for the first stop stop mixer, metering pump metering pump should be shut down. Stop when the suction pipe valve, close the valve in the discharge pipe. Under the condition of freezing may be required to stop the pump, as far as possible to drain the liquid inside the pump and piping, to avoid freezing equipment.
3. long-term disabled equipment should all discharge, liquid pumps and parts, coated with antirust paint.

Three: maintenance

1., attention should be paid to the smooth operation of the mixer, there should be no larger vibration phenomenon, such as larger vibration should be promptly troubleshooting
2. should pay attention to the metering pump pressure gauge, index of state power meters and other instruments. Such as increasing pressure to check the reasons, discharge pipe is blocked or not. The current increases to open the valve is not normal to check whether the pump itself and electrical equipment failure.
3. the temperature rise of the moving parts and bearings should not be too high, and the oil temperature should not exceed 60 degrees Celsius
4. reducer first gas running 500 hours, which should be replaced with new oil, after working continuously replaced once every half a year in the use of a lubricating oil, should always be added. The metering pump replaced once a week, two months after every six months to replace once.
5. in addition to some parts of pump need to change, after 4000 hours operation should be the replacement of wearing parts, operation should be carried out after 8000-16000 hours and check.
