Safety
Workplace health and safety (WHS) requirements need to be observed in accordance with legislation. You need to know the WHS laws governing your job. Revision of CPCPCM2043A – Carry out WHS requirements, before commencing this unit is advisable.
In any work situation you can reduce the risk of injury to yourself and others by using appropriate personal protective equipment (PPE). The types of PPE that you will need include:
- overalls – used for the protection of the installer when working in different conditions
- boots – it is recommended that soft soled footwear is worn while working on roofs, as deep grooved footwear pick up small stones and debris that might damage or scratch the roof sheets
- safety glasses or goggles to protect the eyes from injury when cutting the sheets with a power saw
- ear plugs or muffs to protect the installer’s hearing from excessive noise
- dust masks or respirators to protect the user from breathing in dust or fine particles when cutting the sheets with a power saw
- gloves, for the protection of the installer’s hands when working with different types of pipes, tools and equipment.
Workplace environment and safety
Handling of materials / Manual lifting and handling techniques must always be followed according to WHS requirements. You should move materials into position by hand where possible. Excessive manual handling should be avoided and cranes and other mechanical lifting devices should be employed when necessary.Limited height scaffolds and elevating work platforms (EWP) / Operators must ensure they are familiar with all operating procedures detailed by manufacturers in the elevated working platforms operators’ manual. Personal protective equipment must be worn at all times by the person working in the basket of the EWP. This consists of safety harnesses, safety helmets, rubber soled shoes, safety vests and suitable clothing.
Introduction
In this unit you will look at the skills and knowledge used in installing water pump sets.
Pumps when properly installed and maintained will operate satisfactorily for a long time.
The different types of pumps, motors and connections are:
- centrifugal pump sets
- multistage turbine pump sets
- submersible pump sets.
These will be looked at individually in this unit. Each type of pump set will be described along with the types of motors that can be used, the connections, assembly techniques and the control devices used.
Pump sets
The definition of a pump set is a pump, motor and coupling mounted on a steel frame or base.
The pump may be driven by an electric motor, petrol or diesel engine or perhaps hydraulically and may be arranged vertically or horizontally.
Moving parts guard
Because pump sets have moving parts it may be necessary to have guards installed. Guards may come as part of the pump assembly or manufactured to suit the situation in which they are to be used. Pump guards should be designed to prevent injury to all persons including people working near the pump. A guard should comply with all WHS requirements.
Vertically arranged pump setsQuality assurance
Most companies these days have a policy for assuring quality to the customer. This policy is designed to control the processes used within the company, record keeping, quality of materials used and the way the work is done. Making sure the correct pump is used for a particular application which it is designed for.
You need to be aware of your company’s particular quality assurance requirements. Your supervisor will be able to provide information on your company’s quality assurance policy. However some quality assurance measures such as making sure the finished installation meets the original specifications, or checking all deliveries against the order or delivery docket are just good business practice or even common sense. Other quality assurance measures, such as testing the completed installation, are often regulatory requirements as well. Read information supplied with pump carefully and make sure pump is installed to manufacturer’s specifications so that warranty is not void.
Common terms
Pump sets are systems involving mechanical, hydraulic and electrical components. To understand how they work and how to install and test them there are some terms you should know.
Term / DefinitionCapacity / The volume of liquid that is delivered by a pump per unit time.
The metric units of capacity are as follows:
- small capacities – litres per second (l/s)
- large capacities – cubic metres per second (m3/s).
Suction / The inlet or entry port of the pump.
Discharge / The exit port of the pump.
Head / Head is pressure expressed as a vertical column of water.
The metric units are metres of water (mw).
Static head / The vertical height that the water must be pumped.
Operating head / The difference in pressure (head) between the inlet port and the outlet port of an operating pump.
Suction head / The vertical height difference between the water level and the pump inlet or suction port.
Discharge head / The pressure (head) measured at the pump outlet.
Friction head / The frictional pressure losses which occur as the water passes through the pipe and fittings is expressed as the equivalent vertical head.
Cavitation / The formation of vapour bubbles in the eye of the impeller due to poor entry conditions. Cavitation makes a noise like gravel passing through the pump.
Impeller / The rotating blades or vanes inside a centrifugal pump.
Impellers may have an open or closed face design.
Volute / The casing around the impeller. This casing has a gradually enlarging passageway leading to the discharge port of the pump.
Baseplate / The steel frame on which a pump and motor assembly are mounted.
Grouting / A light concrete mixture that is poured around the baseplate of the pump after the baseplate has been mounted on its foundation.
Plan work activities
You need to plan the job you are about to do and consider how it may affect others. You should do this in conjunction with the others involved in, or affected by the work. Your company may have procedures regarding this that you will need to take into account.
Depending on the size of the job site you will need to coordinate the installation process with the site supervisor or other workers trying to get in and do their part of the job.
Other tradespeople your installation could affect or involve are listed below.
- Electricians.
- Pipe laggers.
- Painters.
- Floor finishers.
- Equipment commissioning personnel.
When installing a pump the installation must comply with the Australian Standard AS/NZS3500 and the manufacturers installation requirements.
Personal protective equipment
In any work situation you can reduce your chances of being injured by using personal protective equipment (PPE).
PPE that you will need to use when installing water pump sets includes:
- overalls
- boots
- gloves
- safety glasses or goggles
- ear plugs or muffs
- hard hats
- fume or dust masks.
Working with hazardous materials
In any work situation there are hazards. These hazards need to be identified and controlled to make the work environment as safe as possible. When you install a pump set you may find yourself working with hazardous materials. If you know which materials are hazardous you can take precautions and reduce the risk to yourself and others.
The following table includes:
- various hazardous materials you may come in contact with when installing a pump
- methods required to protect yourself from contamination
- correct disposal procedures.
Worksheet
Now go to the Worksheet and answer Questions 1 – 7.
Hazardous materials
Material / Used for: / Nature of riskCement / Grouting in pump
Pump foundations / Skin contact causing chemical burns and dermatitis
Inhaling the dust will cause nose and throat irritation.
Dust is irritating and corrosive to your eyes.
Adhesives, Solvent cements and pipe cleaning agents / Gluing insulation
Jointing of PVC pipes / Skin contact and breathing of fumes.
Causing chemical burns, dermatitis and mental confusion or intoxication.
Fluxes / Silver soldering of metal pipe work and fittings / Contact with skin, eyes and breathing of fumes during welding may cause chemical burns, dermatitis and lung tissue damage.
You should obtain and read the material safety data sheet (MSDS) for any hazardous materials you are going to work with. You also need to know where the MSDSs are kept in case you need to refer to them in a hurry (for example to get first aid information). Ask your trainer or supervisor to show you the material safety data sheets for the chemicals you will be using and how they work.
