Installation
3.1.4
Handling after Installation and prior to Service Operation
After installation the equipment should be covered with strong heat shrinkable plastic
cover, as thoroughly as possible with using humidity absorbers inside the plastic cover. Be
careful to protect the coated and plastic surfaces, and particularly avoid hard and sharp
items in contact with the equipment. Secure the equipment to prevent it from tipping over.
Check the equipment regularly, especially for damages on the shrinkable plastic cover and
also check the condition of the humidity absorbers.
3.2
Commissioning
In conjunction with maintenance, commissioning is very crucial for the service life and
functional safety of the hydraulic system.
Checking for the most common faults can minimize faults during commissioning.
The most common faults are:
•
The fluid reservoir was not checked.
•
The unfiltered operating fluid was used.
•
System components were not bled of air.
•
Hydraulic actuator was not bled (seal damage!)
•
Limit switches were adjusted too close.
•
Hysteresis of the pressure switch was not taken into account during setting up.
•
Hydraulic pump was not filled with pressure fluid before commissioning.
3.3
Placing the BHH
When deciding where to place the BHH there are several aspects to consider before
actually mounting the BHH. Type of valve and environment are some of the main aspects.
Following descriptions are instructions and guidelines to be considered in the placing and
pre-installation procedures.
NOTE:
The piping must be strong enough to bear the actuator weight!
Do not use force, to minimize shearing forces and tension on pipelines and components!
CAUTION
DO NOT hold up the whole set actuator with valve using the lifting eye installed to the
actuator top part!
Please refer to the handling means of the valve manufacturer.
3.4
Service Area
There should be enough space around the actuators to ensure easily access and service.
To be able to perform emergency operation by emergency key or hand pump there must
also be enough space around the actuator enabling this operation.
