Centrifugal pump maintenance and care

(1) check the centrifugal pump pipe and joints with loose phenomenon. Rotate the centrifugal pump by hand to see if the centrifugal pump is flexible. (2) Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, lubricating oil should be replaced or replenished promptly. (3) Unscrew the water diversion plug of the pump body of the centrifugal pump and pour water. (4) close the outlet valve and outlet pressure gauge. (5) Move the motor to see if the motor is steered correctly. (6) start the motor, when the normal operation of the centrifugal pump, open the outlet pressure gauge as it shows the appropriate pressure, and gradually open the valve, while checking the motor load conditions. (7) try to control the centrifugal pump flow and head in the range indicated on the sign to ensure that the centrifugal pump at maximum efficiency point of operation, in order to get the maximum energy-saving effect. (8) Centrifugal pump operation, the bearing temperature can not exceed the ambient temperature 35 ℃, the maximum temperature not exceeding 80 ℃. (9) If there is an abnormal sound centrifugal pump should stop immediately check the reasons. (10) centrifugal pump to stop using, first close the gate valve, pressure gauge, and then stop the motor. (11) Centrifugal pump in the first month of work, after 100 hours to replace the oil, after every 500 hours, oil change time. (12) Regularly adjust the packing gland, to ensure normal drip leakage in the packing room. (13) Regular inspection of the sleeve wear, wear and tear should be promptly replaced. (14) Centrifugal pump in winter season, after parking, you need to unscrew the lower part of the drain plug to drain the media to the net. Prevent cracking. (15) Long-term deactivation of the centrifugal pump, the pump required to open all, dry the water, the rotating parts and joints coated with grease installed, safekeeping.

Accelerometer Sensor

Accelerometer Sensor are widely used to monitor vibration in aerospace, automotive and manufacturing applications. Mechanical engineers often use them to diagnose problems with rotating equipment or assess the stability of structures that are subject to periodic stresses (such as monitoring the vibrations caused by trains/trucks crossing bridges, etc.) They are also often used in monitoring for condition-based maintenance, allowing engineers to examine the vibrations produced by a piece of equipment to assess its health, and monitoring the stresses sensitive equipment undergoes during transportation.

The most common method of acquiring vibration data involves connecting Accelerometer vibration sensor and configuring them into a data acquisition system that can deliver high-resolution (24-bit) vibration data at very high sample rates. Modern data acquisition systems can plot, log, filter, and analyze vibration data in real time, and allow using a variety of accelerometer types.
