Fluorine plastic magnetic pump use and maintenance 1. Startup and operation a. Clean up the equipment around the impact of equipment and safety personnel debris. b. Before driving the pump should be filled with liquid to be transported (if the pump is in the case of suction), open the inlet valve, close the outlet gate valve, connect the power. c. Turn on the power, check the steering of the pump is correct. d. Several groups of commissioning 3-6 minutes, such as five anomalies can be put into operation. f. After the long-term shutdown or pump maintenance, when driving for the first time, remove the fan cover of the motor and manually turn the car. Check whether the rotation of the fluorine-plastic magnetic pump is flexible and install the fan cover after confirming that there is no problem. 2. Normal shutdown should be the first gate valve closed, and then cut off the power. 3. Emergency stop immediately stop the motor, and then close the outlet valve and inlet valve. 4. MAINTENANCE AND MAINTENANCE a. Regularly inspect the pump and motor to replace the wearing parts. b. Long-term shutdown when not in use, should clean the pump flow channel and cut off the power. c. It is strictly forbidden to run in air. 5. OPERATING INSTRUCTIONS a. Pay attention to the pressure difference before and after the suction filter. If the pressure difference increases, it means there is foreign matter blockage on the filter. Stop the pump to clean the strainer. b. Whether the discharge volume and discharge pressure meet the specified values; c. Whether there is any abnormal sound or vibration; if there is any abnormal noise or vibration, the cavitation or excessive wear of the bearing is generally indicated. e. Fluorine plastic magnetic pump cavitation occurs: open the pump outlet valve, when the flow reaches a certain amount, a sudden sound and vibration, then continue to open the valve, if the flow does not increase, indicating cavitation. Cavitation should be carried out when the exhaust operation. Caution: The magnetic pump must not operate under cavitation. If it continues to operate in this condition, it will cause early wear of the bearing. f. Whether the current value of the motor exceeds the rated current. g. The temperature of each part of the pump is abnormal or not. h. The pressure of the nitrogen regulator system should be kept within the specified range

The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
