Explosion Proof Pressure Washers High Pressure Pump Unit For Sewage And Slurry

Cleaning accessories include pressure regulating valve, one way relief valve and high-pressure hose.

• Regulating valve(picture 4) To regulate the output pressure and constant pressure of pump.

Turn the nut in clockwise, the output pressure of pump comes up; otherwise comes down. In pressure testing trial, should turn the regulate nut in anticlockwise and open the pressure regulating valve when the system pressure comes to a set pressure to discharge the output pressure. When the customer need the constant pressure ,should turn the pressure to a setup pressure and lock down the nut.

3,Cleaning accessories

Cleaning accessories include pressure regulating valve, spray gun and high-pressure hose.

(1) Pressure adjusting valve: working principle (vide supra)

While washing, turn pressure to working pressure and lock the locknut.

(2)Spray gun:

Spray gun is the switch-controlling component that is connected to the outlet of pressure regulating valve by high-pressure hose. Press or loose the trigger to control jet flow.

三,Assembly and operation manual

1,Install accessories and pressure gauge

Mount on high pressure hose and spray gun, (for installation refer to picture ),. at this time, detach the plugs on the pressure regulating valve and fit with pressure gauge. Connect the pressure-regulating valve to spray gun, then seal each bolted connections with red copper gasket.

2, Operation guide

• Preparation before initial use

• Apply oil into the wheel box until oil surface reaches the middle of oil leveler. Meanwhile, add lubricant into the front end of tank..

Lubricant type: N46﹟machine oil( air compressor oil or hydraulic oil with similar viscosity coefficient)

• Check screwed connections, and tighten them if necessary.
• Check whether the insulated parts of electric motor and starting vessel meet electric appliance standards. For your safety, earth the wire reliably.
• Connect the inlet junction panel on the case to water source (clean and sufficient) by pipe.
