Centrifugal horizontal pump installation drawing correctly

Centrifugal horizontal pump installation drawing right:

1) , centrifugal horizontal pump in place should be done before the following review; Basis of size, location, elevation should meet the design requirements; Equipment should not be missing parts, damage and corrosion, and so on and so forth, nozzle to protect objects and blocking cover should be in good condition; Barring should be flexible, no block, jam phenomenon, no abnormal sound.

2) , factory has assembly, debugging, complete parts should not be taken apart.

3) Leveling is find, pump installation.

based above ground should facilitate the height of the water pump water water pump installation, and should not be less than zero. 1m。 transportation to designated location, lifting equipment installation, based on accurate equipment at is ready, and then put on the anchor bolts and nuts, base to put under the mat iron, with preliminary leveling level, pouring concrete in the anchor bolt.

stay to the expiry of the flat concrete solidification and tighten the anchor bolt cap, each group to spot welding pad iron, based on the surface of hair, wash water to be leveled with cement mortar.

4) , piping installation shall meet the following requirements:

( 1) Tube and internal tube should be clean, sealing surface and the thread should not be damaged, interconnected flanged or threaded axis should, in parallel, the connection should not be forced. Line weight should not be added on the pump, should have their support.

( 2) After line connected to the pump, should not be conducted on the welding and gas cutting, such as welding or flame cutting, should be removed or take necessary measures to prevent slag into the inside of the pump and pump parts.

after the installation is complete pump shaft, impeller should be no friction or jammed phenomenon, otherwise the pump should be disassemble to reason.

( 3) Line configuration appropriate re-inspection according to equipment data and design drawings.

( 4) Each water pump outlet pipe should be installed on the valve, check valve and pressure gauge; When the water pump directly from the outdoor water supply pipe network water, should be installed on the suction valve, check valve and pressure gauge, and shall be installed around the pump is equipped with the by-pass pipe of the valve.

5) And pump vibration isolation and noise: shield on the water pump in and out of the pipe should be installed in a flexible rubber joint or corrugated pipe metal joint; Pipe support hanger, appropriate USES elastic bracket; To create a good vibration isolation effect, base isolation, pipeline vibration isolation and stent vibration isolation must match neat, the vibration isolation pad ( Shock absorber) Area, layer number, number, type and in a flexible coupling model, the number must choose and install according to the calculation results. Shock absorber model, the size of the positioning, matching the number of parameters, such as directly related to the stability of the water pump and vibration damping effect, the determination of the parameters must be through the professional technical personnel accurate calculation to confirm.

water water pump out of the pipe wall, floor, should take measures to prevent solid sound transmission.

6) , water pump debugging points

in the electrical control to ensure safety under the premise of sensitive and reliable, pump single machine commissioning.

will be on the pump outlet pipe valve closed, with the pump start running again gradually open, and check the presence of abnormal, motor temperature rise, water pump, pressure gauge numerical operation, interface closely degree is in line with the requirements, etc.

Most people who see a in operation for the first time are amazed at how well the pool cover drain pump is managed.
