When it comes to nozzles, everyone is not very familiar, and the nozzles are everywhere in our daily lives. The car wash industry also has the largest number of contact nozzles. However, because we didn't understand it, we were very confused when we bought it. So how much do you know about the purchase of cleaning nozzles? Today, Xiaobian will take a look at the cleaning tips and tips for cleaning nozzles ! I hope you can help you without knowing the cleaning nozzle.
Cleaning nozzle buying tips
1. There are many types of nozzles, and the range of options is large.
2. Generally speaking, nozzles for degreasing and water washing processes can be selected with jet nozzles with strong impact force: taking "V" type fan nozzle as an example, the injection angle is 60 ° is the best, with a large impact. power.
3. For the nozzle of the phosphating process, a centrifugal nozzle with good atomization, fine and uniform water particles and weak impact force can be selected: taking the "Z" type cone nozzle as an example, the optimal distance of the nozzle from the workpiece is 40cm. ~50cm, with a spray effect that disperses and atomizes the liquid. The arrangement of the nozzles on the nozzle can be in the form of parallel and cross, and the channel type adopts vertical cross arrangement, and the spraying effect is better.
4, the choice of nozzles are flow, pressure, spray angle, coverage, impact, temperature, material, application, etc., and these factors are often intertwined and mutually constrained.
5. The clip nozzle has two kinds of single-clamp nozzles and double-clamp nozzles. It is mainly for the pressure of the customer. Generally, as long as the pressure does not exceed 3 kg, a single-clamp nozzle can be used, and more than 3 kg of double-clamp nozzles can be used.
6. How big a hole should be opened on the water pipe, because there is a water injection hole on the base of the clamp nozzle, usually 14MM, so when the customer punches the water pipe, don't be too big, not too small, the pinch nozzle opening Too small to fit
Go, too big to leak.
Type of nozzle
Fan-shaped, conical, liquid column flow (ie jet), air atomization, flat nozzle, wherein the conical nozzle is divided into two categories: hollow cone and solid cone; and venturi nozzle (ie, mixing nozzle), strong The name of the cold (hot) tuyere blowing nozzle and special nozzles (such as garden nozzles, cylinder washing nozzles, pipe cleaning nozzles, etc.) exemplifies the performance of the nozzle.
Cleaning nozzle use precautions
1. For each construction, put the nozzle into the tube about 30cm, then pressurize the nozzle into the pipeline. When the nozzle is pulled out of the pipeline after cleaning, the pressure of the high pressure pump should be adjusted to zero. In order to prevent the nozzle from forming a water dragon to incite the operator.
2. Before construction, the nozzle should be carefully checked for blockage. If it is found to be blocked, it should be disposed of in time.
3, pipe cleaning nozzle should be carefully designed and manufactured, the nozzle is preferably evenly distributed on the circumference of the nozzle, and the aperture and the angle of inclination are exactly equal, the main role is to achieve a balanced reaction force.
In addition, when using a high-pressure cleaner to clean the pipeline, in addition to carefully checking the cleaning equipment, you should also pay attention to the mechanical damage in the following cleaning operations:
1. During the cleaning process, if there is no signboard at the wellhead, or if the manhole cover cannot be covered in time after cleaning, it may cause the passing vehicles and pedestrians to fall into the well, causing injury to personnel and vehicles.
2. When using a high-pressure cleaner to clean the pipeline, the high-pressure pipeline on the ground is likely to be rolled by the vehicles passing back and forth, resulting in damage to the high-pressure hose, which will hurt the passing personnel after the high-pressure water is sprayed.
3. Since the iron ladder in the well is to be stepped on when connecting the wells up and down, the ladder may be loose for a long time, and if the operator accidentally falls into the well during the climbing, it will cause a safety accident.
There are many types of cleaning nozzles, so we have to choose according to our own needs when we choose, but we still have to go to the regular store to buy when purchasing! The above is the cleaning nozzle buying tips introduced by everyone today. And the precautions for use are over here. For more information, please stay tuned to the renovation home.
