Fertilizer Injector G1 G3/4 Male Thread 0.4%-4% Drip Irrigation Injector Dosing Pump Item Type: Fertilizer Injector Material: Plastic Adapter: G1 to G3/4 Male Thread Main Machine Inlet Outlet Thread: G1 Male Thread Proportion Range: 0.4%-4% Flow Range: 10L/H-2500L/H Working Water Pressure: 0.5-4.5kg Continuous Operation: >100T Water Temperature Range: 4-30℃ Main Application Areas: 1. Horticulture: Fertilization, storage, control for flowers, fruits, and vegetables. 2. Livestock Farming: Fixed proportion health dosage for livestock and poultry (such as chickens, ducks, cattle, and pigs). 3. Industrial Field: Water treatment, industry, metal processing, fire fighting, etc. 4. Deodorizing solvents, cooling solvents, lubricating solvents and other special solvents in constant proportion dilution. 5. Car wash industry, printing industry, hospitals, wine industry and other industries. I. Dosing device does not come out of the water causes. 1. the direction of the water flow is connected to the opposite, remove the method to correct the direction of water intake. 2. the water pressure is too low, the doser can not start normally, remove the method of installing a booster to increase water pressure. II. The doser does not suck the drug reasons for investigation. 1. When the new machine assembly, suction tube and mouth connection parts can not leak, leakage will cause the doser does not suction, or doser stop using the liquid back to the barrel suction tube becomes empty, and liquid suction to the halfway no longer sucked up. These phenomena are installed suction tube is not installed, air leakage caused by (determine the leakage of a simple method: the dosage tube below the dosage device to a higher position than the dosage device, if the suction is normal, you can conclude that the suction tube is not installed, the interface leakage, remind: serious air leakage or water output is very small can not be used to determine the method) to prevent leakage of air can be installed in the suction tube, the outer side of the mouth coated with a layer of spare parts, the sealing grease in the white box, the sealing grease in the package. When installing the suction hose, apply a layer of sealing grease from the white box to the outside of the nozzle, then insert the suction hose and tighten the suction hose fixing nut. 2. If used for a period of time, the doser work da da sound slow or no da da work sound, exclude methods: unscrew the cover, replace the movement on the two large sealing rings. If the movement work sound normal, the doser does not suction or suction less phenomenon, you can unscrew the middle black nut, the lower part of the pump body as a whole pulled down, replace the drug rod above the small sealing rings, and apply special sealing grease maintenance agent. The small sealing rings on the long rod of the movement must be replaced regularly and coated with maintenance agent, otherwise it will not suck the medicine. III. Water into the barrel of the problem: cleaning the installation of the suction hose bottom valve or replace the bottom valve (generally only disassembled and flushed can be, rarely need to replace the bottom valve) Reason: the water back into the barrel is due to the one way valve there is something dirty, the loss of one way effect. Flush clean on the line IV. Leakage in the middle of the dosage dispenser treatment: use professional tools to unscrew the cover, the inside of the large sealing rings collated, put the right to the dosage dispenser sealing rings groove inside, coated with a little of the dosage dispenser comes with the maintenance agent, tighten it is no problem. V. Inlet and outlet seepage: dosage device installation problems, threaded material tape is not tied, non dosage device problems. VI. The liquid back into the main pipe: the installation of anti siphon valve. The reason is that the pipeline branch design thickness and flow distribution is not reasonable, not the pump problem, is a pipeline design problems. Warning: the dosage must be used within the parameters of the water inlet to install water filters and water pressure regulator valve, frequent switching of water inlet and outlet installed water hammer absorber. More than the water discharge capacity of the doser, or a long period of time, high overwater work, the doser to increase the number of maintenance. Water pressure is best controlled at 0.1-0.2 MPa, which can extend the service life of the doser. Liquid viscosity is large, must reduce the viscosity, otherwise it will cause the internal parts fracture. It is forbidden to lengthen the suction tube privately, the suction tube is too long will damage the movement. Tips: plastic bag inside the three seals are spare parts, save the spare, used for movement seals wear and tear replacement, white box material for the movement seals maintenance agent regularly coated in the movement seals above, reduce wear and tear, increase the use of time
