Pump usage and maintenance

(1) check the pump and pipeline joints are loose, hand pump to see if the pump is flexible, and then try to turn the motor. (2) Connect the flushing cooling water at the pipe connector of the machine. (3) add water to the pump (4) close the outlet pipe gate and outlet pressure gauge. (5) start the motor, when the pump is running normally, open the outlet pressure gauge, and gradually open the gate valve, as it shows the appropriate pressure so far. At the same time check the motor load situation. (6) Try to control the flow and lift of the pump within the range indicated on the pump plate to ensure long-term operation of the pump in the vicinity of the high efficiency point in order to obtain the maximum energy-saving effect. (7) pump in operation, the bearing temperature does not exceed the ambient temperature 35 ℃, the maximum temperature does not exceed 80 ℃. (8) pump in operation, if there is abnormal sound, stop immediately check the reasons. (9) to stop using the pump, first close the gate valve, pressure gauge, and then stop the motor. (10) Note the lubrication of the bearing, grease the bearing chamber regularly. (11) When the pump is used in the winter season, it is necessary to unscrew the water from the lower part of the pump after stopping to release the water and prevent it from freezing. (12) long-term use of the pump, the pump must be removed all, dry the water, the rotating parts and joints coated with grease installed, properly preserved.

Overhead Sectional Door

Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.

The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.

The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147

For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.

A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.

The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.

Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
