Installation Steps And Precautions For Vertical Pumps For Spr

As we all know, correct installation can extend the service life of mechanical equipment and also save costs. The same applies to the installation of vertical pumps for spray towers. If the following occurs when installing a spray tower vertical pump, install it in the correct manner.

 

• The location of the inlet of the water pipe is important.

1. The water inlet of the water inlet pipe is less than the diameter of the water inlet from the bottom and wall of the pool. If there are sand and dirt on the bottom of the pool, the water inlet from the bottom of the pool spacing less than 1.5 times the diameter, will form a pumping into the water is not smooth or sucked into sand debris, blocking the water inlet.

2. When the water inlet of the water inlet pipe is not deep enough , it will cause the water around the water inlet pipe to whirlpool, affecting the water inlet and cutting the water output.The correct installation is as below: Small and medium-sized pump into the water depth shall not be less than 300~600mm, large pumps shall not be less than 600~1000mm.

 

• When setting up the bottom valve, the next section of the inlet pipe is not straight.

Such a device, the valve can not close itself, the formation of water leakage. The correct device is: equipped with a bottom valve inlet pipe, the next section of the good is straight. If you can't install it straight due to terrain constraints, the angle between the water pipe axis and the horizontal plane should be more than 60°.

Inlet pipe with many elbows.

 

• If more elbows in the water inlet pipe, will add some resistance to water flow. And the elbow should be turned in the straight direction, not allowed to turn in the horizontal direction, to avoid the collection of air.

 

• Installation of water inlet piping, the horizontal section of the horizontal or upward cocking.

Doing so will make the inlet pipe collection of air, drop the water pipe and spray tower vertical pump vacuum, so that the pump suction head down, cutting the water output. The correct practice is: its horizontal section should be slightly skewed to the direction of the water source, should not be horizontal, not to mention upward.

• Shower tower vertical pump inlet and elbow directly connected.

This will make the water flow through the elbow into the impeller when the dispersion is uneven. When the diameter of the water inlet pipe is larger than the pump inlet, should be installed reducer. Reducer pipe plane should be installed in the upper part, some beveled installed in the lower part. Otherwise, the collection of air, water cuts or pumping water, and impact sound. If the water inlet pipe and pump inlet diameter flat, should be added between the pump inlet and elbow a pipe, straight pipe length shall not be less than the diameter of the water pipe 2 to 3 times.

 

? Chemical vertical pump outlet in the outlet pool above the normal water level.

If the outlet is above the normal water level in the outlet pool, although the pump head is increased, but cut the flow. If, due to terrain conditions, it is necessary for the outlet to be higher than the water level of the outlet pool, the pipe should be installed in the mouth of the elbow and short pipe, so that the water pipe becomes a siphon, down the height of the outlet.
