Pump assembly and disassembly:

Pump assembly of parts should be checked before, with the surface of parts, especially the mechanical seal friction surface should be clean, there should be clear sealing surface scratches and cracks, bumps and other defects, if the defect should be replaced.

Assembly:

The retaining ring onto the motor shaft, the bolts fastening the seat in the motor.

In the mechanical seal stationary ring apron coated with Vaseline or other lubricants, the components along the axis of the stationary ring pressed into the seat and clean the sealing surface coated with grease, and put on other seal parts, fitted with flat key, impeller and washers, and bolt clamping.

Note: Seal mechanical seal stationary ring apron lateralization during installation is easy, this will result in mechanical seal leakage, the installation should be carefully examined.

Block of the sealed end in the amount of surface coated with oil, fitted with O-ring. Install O-ring, the ring easy to fall off and collapse, be careful to avoid leakage

Lift motor assembly, the impeller down, curl set into the pump body, and then bolt, and put on the tube block and bleed plug.

Hand turning the rotor, check whether the cable wiring.

Demolition:

Instead of installation steps.

Note: The demolition of the mechanical seal, can not directly hand percussion hammer or hammer stationary ring, applied gently tap the wood, slowly remove the static ring. Difficult to remove any dirt accumulation caused, should be cleaned after the demolition.

Unit installation, operation and maintenance of:

Installation:

Installation, to be elected from the recent local transmission fluids, installed in the pump suction height of the smallest and shortest of the suction line at

Note: The unit should ensure that the distance between the obstacle and the surrounding greater than 150 mm, the motor fan to have access to sufficient air source.

When the pump is used in place more stringent vibration requirements, you can use the shock absorber (pad), subject to manufacturer's instructions to install.

Piping installation should be secured to the pipe flange close to the pump should have sufficient support rigidity, not allow the pump to withstand the weight of pipeline pressure.

The installation of pumps to avoid direct sun and rain.

Pump inlet should be installed vacuum gauge, pressure gauge outlet flange should be installed to observe and control the operation of the pump. The actual gauge pressure range should be 2 to 3 times better.
