What you should know about high pressure washer
CU(cleaning unit )=PSI(pounds per square inch)*GPM(gallons per minute)
CU(cleaning unit ):cleaning unit is multiplying PSI by GPM, useful comparing models , the higher CU the more cleaning power your pressure washer has .
PSI(pounds per square inch):A pressure washer’ PSI rating is the maximum amount of force (pressure ) discharged by the pressure washer .The higher the PSI, the more cleaning power available and the more things you will be able to clean .
GPM(gallons per minute):A pressure washer’s GPM rating refers to the water flow during one minute of operation . The higher the GPM , the faster you will be able to clean .
Operator errors of high pressure washer that will cost you much money
Cause 1. Running the pressure washer without water
Normally this will destroy the pressure water pump within minutes.
Cause 2.Running the pressure washer in extended by-pass
By-pass is when the pressure in on , and the trigger is off the water is re-circulating inside the pump manifold , the water temperature builds as time goes on . It is not allow to lets the unit run in by-pas for more than five minutes . This is because the heat buildup quickly damages the pump. Therefore , you have to run off the pressure washer every time you are not going to be spraying , even for some unit that installed with a thermal relief valve that will release the hot water and the pump feed with cold water to cooling down .
Cavitation is caused by air getting into your pump .The air can damage your pump as it rapidly expands and contracts . The first sign of cavitation is loss of pressure and a hammering noise. The cause of cavitation is lack of water or air getting into the system .For example , your pressure washer is rated for 4.0GPM but the inlet hoes only provides 3 GPM, then the pressure washer pump will try to pumping 4.0GPM.The suction due to the lack of water will pull in air and cause cavitation. The only solution to cavitaion is to feed your pump the required amount of water and to make sure there are no leaks in the water inlet system .
In the winter the water left in the pump after use will freeze and possibility of damage to the pump .The typical remedy for this is putting anti-freeze in the pump .So always keep the pump run for a extra seconds and pump our the excess water .
Cause 5.No lubrication and lack of lubrication
High-pressure pumps, like gasoline engines , required oil to lubricate transmission mechanism , the crankshaft, connecting rod and plungers . The oil is needed to keep the pump parts cool and turning freely . No oil and low oil will causes permanent damage to the pump. When the oil leak out , or water gets into the pump oil , the pump parts will overheat and begin to break apart. Always check your oil level and maintain the correct amount and type of oil in the pump to prevent damage .
Comparison of different kind of high pressure washer
Direct –drive Gas high Pressure Washer
A “Direct Drive “ pump has a hollow shaft , which simply slides onto the drive shaft of a engine and the flange on the pump is mounted to the face of the engine , so the pump spins at the same speed as the engine—typically 3,600RPM.This system has the advantage of being simple , with few moving parts , and therefore is less expensive .The disadvantage is by having the pump spin as much as the engine the bearings get more war and tear , reducing the life span of the pump .
Belt –drive Gas high Pressure Washer
Belt-drive units use pulleys and belts to slow the speed of the pump . Where the engine spins as 3,600 RPM the pump will be slowed from 1,100 to 1,600 RPM depending on the pulley and belt set up. This system ensures long pump life because the bearings do not get as much wear and the pump is isolated from the heat for engine , being separated by the belts and pulleys . The disadvantage of this system is there is some loss of efficiency due to the additional frication from the blest and pulleys and more maintenance required adjusting the belts .
Gear-drive gas high pressure washer
Gear-drive units use an extra gear-reduction system installed between engine and pump , Gear Drive installation will not only keep the heat transfer down , but also make the pump turn at half speed which will result in longer life of the pump bearings and seals . Compared with belt drive system , the gear drive unit features more compact and less efficiency loss . This consequently makes such machines industrial and allows the pump continuously running .
