AA4C Automatic 4 steps Chemical Dosing System for Water Recycling for car washing machine Sewage treatment equipment

Preface

Thank you for using our company's HC-S type rotary blower. Before use, please read this manual thoroughly. Based on a full understanding, properly care for and operate the blower. Just like humans, the blower's condition changes with various conditions every day; continuous operation under different states can damage the blower. Regular maintenance, inspection, and correct usage methods are crucial for ensuring the blower operates smoothly and lasts longer.

Composition of the Rotary Blower

When air pressure between 0.1 kgf/cm² and 0.5 kgf/cm² is required, use this blower. The blower consists of the following main components:

1.Motor

2.Air Filter

3.Blower Body

4.Air Chamber

5.Base (Oil Tank)

6.Oil Drain Valve

Introduction to Main Components

1.Blower Body

The blower body is the heart component that produces compressed air. This machine adopts the eccentric cylinder design developed by the Japanese Toyo Company, which ensures high processing precision and low operating noise.

2.Air Chamber

The air chamber stores compressed air from the blower body continuously and reduces pulsation during discharge. It also serves as an oil-air separator. The air chamber is equipped with a safety valve and pressure gauge.

3. Air Filter

The air filter plays a crucial role in allowing clean air to enter the blower. Once dust or contaminants enter the main unit, they will wear down the blower, contaminate the oil, and shorten the lifespan of the blower.

4. Drip Nozzle

The drip nozzle is a component designed to drip an appropriate amount of lubricating oil into the main unit of the equipment. This model employs a unique drop-by-drop structure innovated by Japan's Toyo Company, which is meticulously manufactured to prevent oil blockages and to ensure that too much oil is not dripped into the system.

5. Base (Oil Reservoir)

The base of the blower serves as the lubricating oil reservoir. It utilizes the pressure differential between the blower's intake and exhaust ports to automatically and continuously press lubricating oil into the main unit of the blower. The oil that is dripped into the main unit separates from the air in the air chamber and then returns to the oil reservoir in the base.

6. Motor

The motor is not resistant to moisture; please ensure that it remains dry. Also, pay attention to the direction of rotation of the motor—it should be consistent with the directional markings indicated on the blower.

The working principle of the fan

When the eccentric device rotates the rotor in the cylinder body, the 4 blades in the rotor groove produce reciprocating motion, and the air is sucked in, compressed and discharged to form a fan. Friction heat is generated by friction between blade and rotor and cylinder block. Therefore, when the fan is running, the necessary lubricating oil is dripped into the cylinder body by the drip nozzle to lubricate the friction surface to reduce friction heat and friction noise; And a layer of oil film is formed between the components to maintain the tightness of the fan. The lubrication system is a circulation device that automatically supplies oil by using the pressure difference generated when the fan works, so it can not run with empty load! Fan storage, installation, test operation precautions

(1) Storage

1. The best storage temperature of the fan is 15℃. If it cannot be met, it also needs to be stored in a room without vibration and maintained at room temperature. 2. The shell, frame and other components of the fan have been treated with rust prevention at the factory, but the paint needs to be checked regularly and repaired if necessary. To prevent internal parts from rusting, remove the air filter and seal the air intake with a plastic film. 3.6 When the fan is not in use for a long time, it should be tested regularly. The hand plate is equipped with wheels once every half a month to ensure that the blades are not too heavy and there is no stuck when rotating. Test the edge performance of the motor every three months to ensure that the resistance is more than one megaohm. 4. The fan has been lubricated before leaving the factory. If it is stored for a long time, please replace or add lubricating oil before use to avoid condensate or foreign matter in the oil in the body.

(2) Installation

1. Pay attention to safety when moving the fan to avoid damage and impact on the fan. And the fan can not be carried upright to prevent the lubricating oil from pouring out of the tank. Ventilation outlets should be provided in the air room and ventilation fans should be installed. The ventilation outlets should be located in the upper and lower places to facilitate air convection. 2. This prevents the fan from running normally due to the high temperature in the equipment room. 3. It is best to have muffler materials around the inner wall of the equipment room to reduce noise. 4. The fan is forbidden to be installed in the open air. In the case of outdoor installation, a canopy should be put up to prevent rain from entering. 5. The fan should be installed horizontally. 6. The diameter of the air distribution pipe should not be smaller than the exhaust air diameter of the fan, and pay attention to the cleaning of the pipe. The gas pipe should be installed above the water surface to prevent the water in the pipe from causing excessive pressure when starting.7 7. Pay attention not to screw the check valve to (the protruding part of the check valve should face up) when taking over. 8. Please connect the wire correctly and note that the motor steering is consistent with the fan rotation direction mark. 9. When two fans are operated alternately, it is hoped that frequent switching of the fan should be avoided in a short period of time The continuous operation time of the fan is not less than 24 hours.

(3) Trial operation

1. Check whether the oil in the tank is up to standard. (Engraved line marks on the oil scale) 2. Before starting the fan, please take down the air inlet filter and pour about 30m1 oil into the main engine so that the oil is evenly distributed inside the main engine. (Turn a few times with your hand) 3. Check whether the tightness of V-belt is suitable, if it is too loose, please adjust. 4. Check whether the safety valve is set at the specified pressure position. If the working pressure is 0.3kgf/cm, the opening pressure of the safety valve is 0.33kgf/cm. In the test run, you can manually adjust the exhaust valve boost pressure to open pressure, adjust the safety valve to open, adjust the safety valve to open. (The pressure is 1.1 times the working pressure) 5.Turn on the power to start the fan, please pay attention to the following; a. Whether the direction of the fan steering is consistent with the direction indicated by the steering mark, if not consistent, immediately stop and adjust the motor wiring. b. Check whether the pressure gauge indicates pressure. (The sewage treatment tank must be filled with water before running the fan, otherwise there is no pressure at the fan exhaust port, the fan is not lubricated.) c. Observe whether there is oil dripping out of the drip nozzle (12-158 drops/minute), and observe whether there is oil flow in the transparent return pipe. d. Check whether all parts of the motor and phoenix are running normally, whether the temperature is normal, and whether there is abnormal sound. Fan maintenance points 1. Check the lubrication system a. Daily check whether the amount of oil stored in the tank is lower than the minimum scale line, if the oil is insufficient, please refuel. (The oil brand is IS0 standard N68 anti-hydraulic oil, and the oil brand can be appropriately reduced in low temperature and cold areas) b. Daily check whether the oil is mixed with water and other dirt and deterioration, such as deterioration, please replace the hydraulic oil in time, under normal circumstances, replace the hydraulic oil at least once a year. c. Clean the oil filter daily. d. Daily check whether the dripping condition of the drip nozzle is normal. If the drip nozzle is dirty, remove the adjusting screw to clear it For washing. 2. Inspection of air filter Daily check whether the air filter is dirty. If dirty, remove the air filter, unscrew the butterfly nut, remove the cover, and clean the filter sponge. (Be careful not to drop stolen goods into the fan host when unloading the filter) 3. Inspection of triangle belt After the fan runs for a period of time, the triangular belt will stretch. At this time, the fixing bolt of the motor should be loosened, the motor9 should be moved, the triangle should be tightened to the appropriate position, and the motor fixing bolt should be tightened, and the end surface of the motor pulley and the fan pulley should be on the same plane. At the same time, check whether the top tightening screw of the pulley has been sent off. If it is loose, please hold it tightly. 4. Check the flexible condition of the safety valve on a daily basis. If it is not flexible, please clean and debug it to ensure reliable opening and closing. 5. Check and repair the parts for oil and gas leaks on a daily basis. If it cannot be repaired, please inform the manufacturer immediately. 6. Clean up the fan factory every day, keep it clean and well ventilated. 7. Check the operation status of the fan and motor frequently. If you find that the noise and temperature are not normal, you should stop and repair it in time.
