The use of pipe pump Pipeline pump is pressurized transmission pipeline to solve the pipe pressure is too low and developed a new pump, horizontal centrifugal pump than the current application has more advantages. The main points of its use are: 1) test work: Check whether the connector is loose; hand crank the coupling so that the rotor turns a few times to see if the unit rotation is flexible, whether there is noise and uneven feeling, to determine the pump Is there a foreign body or the shaft is bent or not, the seal is installed incorrectly; Check the seal cavity clean No. 20 lube is filled with 1/2 cavity space; pump unit surface is clean; unit to no-load test. 2) manual start: filling pump (first time), slightly open the outlet valve, start the motor, the pressure rise and confirm the smooth operation of the pump group outlet valve to the operating conditions. 3) Operation check: When the pipeline pump is operating normally (frequency conversion), it should periodically check and record the readings of the ammeter, voltmeter, vacuum gauge, pressure gauge and flow meter of the pump set. Unit vibration, noise, temperature rise is normal. Shaft seals should not have significant aviation fuel leaks.
Roller Shutter Door
Roller shutter door , also known as "shutter door", lots of panel pieces connected together, fixed in the guide rail , take above reel as the center of rotation.
Roller shutter door is used for commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or residential.Electric roller shutter door, especially for large openings, inconvenient to install the ground door , quick opening effect. Such as for the garage door, shopping mall fire shutter door.
