The high-pressure pipeline cleaning vehicle is a type of sanitation-specific vehicle, which is powerful and easy to operate. However, in order to ensure the normal operation of special vehicles and to prolong the service life of vehicles, it is necessary to do relevant maintenance measures for such vehicles. However, the maintenance steps for this kind of pipeline cleaning truck are very particular about what you really understand, and look at how the following knowledge is introduced. First, in the cleaning process of the high-pressure pipeline cleaning vehicle , the temperature above the vehicle body must be reduced to less than sixty degrees to perform cleaning. It is also advisable to maintain the ambient temperature within forty degrees. In addition, the squeegee above the cleaning squirt gun and the vehicle body must be maintained at more than fifteen centimeters, and the order of rinsing of the vehicle must be performed from the top of the vehicle to the two ends in sequence. Before the vehicle is flushed, it is necessary to use a mist-like flow to flush the water at the ends of the vehicle. It is not possible to clean the heat sink of the condenser directly in the mode of the water column to avoid damage to the machine. A second, high-pressure pipe facing stubborn stains remaining on the cleaning car, we recommend using a good effect after water addition be combined with cotton, scrubbing, wiping again, then wrung water, dipped in professional washing liquid was wiped at stubborn stains . It is possible to clean the high-pressure pipe cleaner to a completely stain-free effect. Third, when using a high-pressure water gun to clean the cleaning vehicle, it is mainly to use a high-pressure water gun to gradually flush from the top to the bottom of the car body, and to avoid the engine parts of the car, orderly flushing in order to be able to contaminate the mud on the car body. Sand washed away. However, in the process of cleaning the high-pressure pipeline cleaning vehicle, it is necessary to pay attention to the comprehensive flushing of the chassis portion of the vehicle, and thoroughly clean the edge portions of the vehicle, the bending zone, the fender, and the like. In particular, where there is a lot of silt and dirt in the wheel and brake discs, fenders, and front grilles, thorough washing must be done to keep the vehicle clean.
Air valve
The
new double-canisters exhaust valve consists of a big canister and a small one.
When
there is no water in the pipe, the canister in the body drops down to the full
opening place. When water coming in, the air in the body is released from the
big canister, then water can be filled into the pine immediately. When there is
no air in the pipe, water comes into the valve cavity and causes the two
canisters rise up to the closing place. And the big canister stays closed so as
to improve the capacity of transporting water and to economize energy.Since air is
often dissolved into water, when transporting water, the air is released from
water continuously , however, when reaching the quantity, the small canister
will drop down with a small amount of air released from air vents . Otherwise
the air accumulating on the top of the pipe will reduce the pipe system`s
capability of transporting water.
When there is
negative pressure in the pipe, the big canister drops down and the discharge
hole is open. Then the valve takes in air in good time so that it can avoid
affecting normal water supply due to the negative pressure on the pipe.
1.Unique design:
The two canisters are made of non-toxic
engineering plastics of high strength., with concise structure, light weight,
reliable and stable exhausting.
Inside and outside surfaces of the body, cover
and dust-prevented cap are all coated with epoxy resin powder with no iron
exposed. Materials of inner components are made of stainless steel and
engineering plastics so as to prevent corrosion and to ensure purity of media.
The sealed seat, made of bronze, improves the
ability of anti-abrasion, and prolongs service life.
2.Excellent anti-corrosion:
Inside
and outside surfaces of the body, cover and dust-prevented cap are all coated
with epoxy resin powder with no iron exposed
3.Sanitary standard:
Non-toxic epoxy resin powder used
comply with sanitary standard GB/T 17219-1998.The coated resin is in accordance with
standards of drinking water.
4.Tested summary:
The media
is air. In the procedure of the test,
the air temperature shall keep between 5℃ and 45℃. The fluctuation of air flowing value shall be
within 4% and that of the pressure value within 5% while that of air
temperature value within 2%.
Sealing
test at a low pressure. When the
pressure goes up to 0.05 Mpa, 0.1 Mpa, 0.2 Mpa, 0.3 Mpa, 0.4 Mpa, 0.5 Mpa, the
valve maintains the pressure at 12mins with no visually detectable leakage of
the sealed surface.
Repeated
test of exhausting Putting water into
the valve and discharging air every 8-9 seconds. Then increasing the pressure to
1.6 Mpa , keeping it for 2mins before releasing. Conducting leakage test for
250 times with the result that there is no visually detectable leakage and no
structural damage. Then testing the sealing at a high as well as low pressure,
no visually detectable leakage.
Repeated
test of airing Injecting air into the
valve till the valve closes fully, then cutting off the air till the valve open
fully. Repeating leakage tests for about 25000 times with the consequence of no
visually detectable leakage and no structural damage. Then testing the sealing
at a high as well as low pressure, no visually detectable leakage.
Test of the
valve's endurance The valve is poured by
water with a pressure of 1.6 Mpa at a temperature of 50℃and maintaining it for five days, then
checking whether the valve can be normally opened or not after releasing the
pressure.Testing the leakage, resulting in no visually detectable leakage and
no structural damage. Then testing the sealing at a high as well as low
pressure, no visually detectable leakage.
