1. Single screw pump in operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C.
2.If abnormal sound of single screw pump is found, it should stop immediately to check the reason.
3. Single-screw pump to stop using, first close the gate valve, pressure gauge, and then stop the motor.
4. Single screw pump in the first month of work, after 100 hours to replace the oil, after each 500 hours, oil change time.
5. Regularly adjust the packing gland to ensure normal drip leakage in the packing chamber (it is advisable to leak into a drop).
6. Check the wear and tear of the sleeve regularly, adjustable pressure slag pump should be promptly replaced after wear and tear.
7. Single screw pump used in winter season, after parking, you need to unscrew the lower part of the pump oil drain plug to put the media net. Prevent cracking.
How to maintain a single screw pump
8. Long-term deactivation of single screw pump, the pump should be disassembled, dried oil, the rotating parts and joints coated with grease installed, properly maintained.
9. Check the single screw pump and pipe joints and loose or not. Turn the single screw pump by hand to see if the single screw pump is flexible.
10. Add bearing lubricating oil to the bearing body, observing the oil level should be at the center line of the oil, the lubricating oil should be replaced or replenished promptly.
11. Unscrew the single-screw pump oiling plug, pouring oil (or pulp).
12. Close the outlet valve and outlet pressure gauges and import vacuum gauge.
13. Jog the motor to see if the motor is turning properly.
14. Start the motor, when the single screw pump is running, ZYB-B adjustable pressure gear pump to open the outlet pressure gauge and import vacuum pump, as it shows the appropriate pressure, and gradually open the valve, while checking the motor load conditions.
15. Try to control the flow and lift of the single screw pump in the range indicated on the plate in order to ensure that the single screw pump at maximum efficiency point of operation, in order to get the maximum energy saving effect.
Dibenzoylmethane (DBM) is a chemical substance with a molecular formula of C15H12O2 and a molecular weight of 224.25. Dibenzoylmethane is used as a co-stabilizer in the calcium/zinc hydroxy acid salt stabilization system for the manufacture of PVC mineral water bottles. , an analytical reagent for the determination of carbon disulfide and thallium. Dibenzoylmethane is a colorless rhombic flaky crystal, easily soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution, very slightly soluble in water.
