Knapsack Sprayers are useful garden tools that help control the growth of plants. It can be a lifesaver when it is needed. It has been around for decades. Follow hangyu plastic and get some information on what a knapsack sprayer is, and how to use one.
Traditional knapsack style sprayers were a cylinder shaped container where you put seeds or cuttings into, along with hoses attached to the bottom. The gardening worker held the nozzle in his hand with his right hand, and a small pump handle with his left. To maintain the pressure in the reservoir, the gardener held the nozzle steady with his hand while pumping the seeds or cuttings through the hose. Traditional knapsack sprayer were more convenient than the automatic and powered sprayer devices that were developed later, that required to be held by hand. All you did was open the lid, set the control knob, and spray, just as you would with a traditional hand held vacuum.
Automatic or powered Knapsack Sprayer and systems are available today. There are three types: manual, electric and solar. Each has its advantages and disadvantages. Manual sprayers are less costly than the powered models, although the automatic system offers more convenience. In essence, the manual tool offers less effort while spraying, but greater versatility.
A manual knapsack sprayer usually has a small steel cylinder and piston, a mixing valve, and a pressure relief valve. It uses a small amount of water to mix the herbicide and the water for the air release. The pressure of the water is adjusted by a lever that is rotated to move the piston forward or backward. As a result, the output varies according to the volume of the spray and the amount of water used to generate it.
This is the second type of automatic sprayer. It is called an engine type sprayer. It consists of a high-pressure air nozzle, a mixing chamber with a variable-speed fan and an air tank that stores the required air. The air is compressed by the fan, which creates a low-pressure stream for the spray.
Thirdly, there are power sprayer units. They are a combination of the two types. They do not use a water reservoir, but instead a motor to drive a continuous sprayer wand. Like a normal sprayer, water is sprayed for the herbicide. A very powerful fan creates a superheated jet stream, which sprays the herbicide at very high pressure and speeds.
The fifth and last type of knapsack power sprayer is called the bagless unit. It consists of a self-contained air tank, a spraying device and an electric motor. The bagless model saves more energy than its engine type counterpart.
The Knapsack Sprayer has been in use since the early days and is still being used in the modern herbicide production facilities. It provides high efficiency herbicidal spraying capability with high-quality performance and outstanding durability. It makes herbicide application simple and easy for personnel working in a chemical manufacturing plant. It offers the right spray application equipment for your effective and economical herbicide spray operations. Its numerous applications make it a product of high quality and reliability.
It features a three stage spray cycle and manual controls for the first stage and the second stage. It can operate by one of its two switches - the constant pressure switch or the constant speed boost button. It has an auto shut off feature that ensures the stoppage of operation after the desired spraying height is achieved. It uses hydraulics and high-precision technology to achieve the 300 kpa pressure and maximum effort values. It can handle all types of liquids and is ideal for continuous spray coverage of large areas.
It has a safety guard that prevents the operation of the product when the center of gravity is in excess of zero degrees. It features a high-performance nylon fabric cover for superior protection from accidental hits, cuts, abrasions and debris. It also has an adjustable wrench for greater leverage and a stainless steel bolt for reliable holding power. In addition, it has a significant normal distribution and a high degree of durability and tensile strength.
Its maximum pressure and tensile strength make it highly suitable for lifting and handling of large, heavy objects. Its ability to operate with a reduced engine power means lower fuel consumption and lower maintenance and operating costs. It can effortlessly and quickly saturate an area with its effective jet stream and successive spray nozzles.
