Operating Guide for High and Low Temperature Circulating Pumps

High and low temperature circulating pump can transport clear water or liquid medium similar to clear water. It cannot be used to transport liquid medium containing high viscosity and volatility, but aluminum alloy diaphragm pump can do it. High and low temperature circulating pump has a wide range of applications. High and low temperature circulating pump is especially suitable for garden sprinkler irrigation, high-rise building water supply and drainage, chemical industry, municipal administration and other occasions. Then, let's learn about the operation guide of high and low temperature circulating pump together!

Preparation before starting

(1) Check whether the fixing bolts of each component are loose, whether the end clearance is within the specified range, whether the two shafts of the coupling are concentric, and whether the sealing performance is good.

(2) Check whether the lubricating oil level is on the center line of the specified oil mark, and cannot be too high or too low.

(3) Open all intake valves and open the bleed valve. Before driving, the high and low temperature circulating pump should be filled with water and exhausted, and then the valve on the outlet pipeline should be closed.

(4) Rotate the trolley several times to check whether the rotation is flexible and there should be no abnormal noise or jamming.

Up and running

(1) Check whether all preparations are made.

(2) Turn on all switches of various instruments.

(3) Unscrew the start button, check whether the steering of the low-temperature circulating pump is correct, whether the operating sound, current, pressure, etc. are normal, and stop immediately if there is any abnormality.

(4) After the speed of the high and low temperature circulating pump is normal, slowly open the outlet valve and adjust the flow and pressure to the required requirements.

(5) The temperature of the circulating pump and motor bearings should not be higher than 80 during operation.

(6) Regularly check the vibration and noise of the high and low temperature circulating pump. If any abnormality is found, it should be eliminated immediately and recorded.

Regulations on safe operation of high and low temperature circulating pump

(1) During the start-up and operation of the high and low temperature circulating pump, the operator cannot touch the rotating parts to prevent danger.

(2) In the process of cleaning the lifting pool of the pump room, the operating procedures should be formulated in advance according to the actual working conditions.

(3) When there is a sudden power failure in the pump room or a major accident occurs to the equipment, the gate valve of the accident discharge port should be opened, the gate valve of the water inlet should be closed, and the department head should be reported not to carry out maintenance work after power on without authorization.

(4) When the high and low temperature circulating pump is running, if a shaft failure is found, stop the pump immediately and contact professional maintenance personnel to check the cause of the failure.

(5) It is strictly prohibited to frequently start the high and low temperature cooling circulating pump.

(6) After the high and low temperature circulating pump starts and runs stably, the operator can leave the job.
