HL 962

Assembly Stand for Pumps

Technical Description

Exchanging pumps for inspection or repair is a key element of a maintenance engineer's work.

With HL 962, trainee maintenance engineers can be instructed in the practical tasks involved in exchanging different pumps. To this end, the stand features a three-phase electric motor as its drive and an intake and delivery line with manometers. Four different pumps are available as add-on machines. The position of the electric motor can be adjusted in three directions for alignment purposes. The alignment can be checked using a straight-edge or two dial gauges. The potentiometer-adjustable speed and the power output of the electric motor are displayed digitally on the switch cabinet.

The stand forms a closed water circuit in conjunction with a pump and the central water supply (tank system HL 960.30 + piping system HL 962.32). The characteristic curves for the pumps can be obtained using this set-up. The accessory pumps HL 962.01, HL 962.02, HL 962.03 or HL 962.04 are typical centrifugal pumps, widely used in process engineering.

Learning Objectives / Experiments

In conjunction with an accessory pump (standard chemicals pump HL 962.01, canned motor pump HL 962.02, side channel pump HL 962.03, standard chemicals pump with magnetic clutch HL 962.04) and a suitable water supply, e.g. HL 962.30 with HL 962.32:

- Mounting of the pump and alignment of the electric
motor
- Familiarisation with various methods of aligning the
motor and pump
- Commissioning and leak testing
- Recording a pump characteristic
- Comparison of various pump types (only if multiple
pumps are available)

Features

* Mounting of different pumps (available as
accessories)₁

* Alignment of motor and pump by different methods₁

* Base unit when constructing a complex piping system
