About YLG series of pipeline pump Product Overview: YLG series pipeline pump is the company's single-stage single-suction pump in accordance with the characteristics, referring to domestic and international standards, using scientific hydraulic model designed by a series of products. Its main features are: small size, light weight, less space; with bipolar motor, low power consumption, pumping strong. Its main advantages are: structured, compact, low noise, energy efficient, durable, easy to maintain. Mainly used for pumping liquid water at room temperature and physical and chemical properties similar to water, widely used in water supply, cooling, fire protection, electroplating, chemicals, sewage treatment, and other systems and machinery equipment. Technical parameters: Model significance: Flow: 1 ~ 250 m3 / h Head: 8 ~ 50 m diameter: 32 to 125 mm motor power: 0.37 kW ~ 15 kW Speed: 2900 r / min Media Requirements: ≤80 ℃ of water or physical chemical properties similar to water Note: If the customer needs, can be made of high temperature pumps and pumps with special voltage for customers. Structure: The pump is mainly composed of four parts the pump impeller, the seat (connecting seat), motor and other components, and its structural characteristics:? Pump and motor coaxial, the seat (seat connector) directly connected to the pump and motor, motor change the standard Y series motor shaft extension shaft. ? The pump inlet and outlet on the same horizontal axis design allows the pump as the valve is installed anywhere in the pipeline, and easy to install. ? Pump seal made of high quality and durable mechanical seal, no leakage. ? Pump inlet with the vent outlet flange edge, easy to accumulation of gas discharge pump and test water pressure. ? Bottom of the pump is provided with a support system that allows the pump fastened on the basis of ease of installation and increase the stability of operation of the pump. ? Cast on the pump or motor pump motor rotation direction indicator posted to prevent the installation of pumps to reverse the adverse operation of the pump, the other pump motor terminal box is attached power supply wiring diagrams, user-friendly installation wiring. Materials: Pump body, connecting blocks, impellers are made of gray cast iron material used HT200. If the user requires the use of a copper alloy, stainless steel and imports of mechanical seals, or high temperature pumps shall especially when ordering. Installation and use of the pump precautions pipeline pump installation requirements: 1. Installation height should be less than the permitted height minus feed line loss of vacuum suction. Under standard conditions, the installation height ≤10.3- (NPSH) r-0.5-hw, the suction pipe hydraulic loss; 2. Pump outlet flange on the pressure gauge should be installed in order to observe and control the pump operating conditions ; 3. The pipeline may not bear the weight of the pump; 4. pumps should be installed in well ventilated areas, outdoor installation shield should be added to avoid sun exposure and rain; installation: 1. Before installation: check whether their deformed or damaged during transport, the fasteners loose or fall off. 2. Inlet and outlet pipe installation configuration: the pipe should be installed to minimize the pipeline fluid resistance principle. Intake pipes should be added at the filter to prevent impurities or hard rigid solid particles into the pump chamber seal or water damage leaves and cause water pump leakage or abnormalities; intake pipe should be added at check in order to water. 3. Wiring: nameplate requirements must correct wiring, wiring, terminals must be firm, not allowed to have loose, otherwise, it will cause poor contact caused by burn-in phase. Overload protection device must be used on the wiring lines and to adjust the protective device settings based on the current size of the motor nameplate requirements. 4. Installation: vertical pump 1> suction water level above the pump: Single pump and dual pump can be connected in series or in parallel as shown in a diagram b; 2> sucked under the water level below the pump: If pumping pool water as shown in c. Pump Installation Key start: 1. Before starting the pump should open the inlet valve and the pump discharge valve plug, close the outlet valve, the pump chamber filled with water, the pump can be started normally. 2. Jog motor, check whether the steering direction (from the motor that rotates clockwise) run indicated by an arrow: 1. Pump after starting gradually open the outlet valve, adjusted to the desired operating point. 2. The pump is running, operating point of not more than traffic flow performance parameters given in the table of large flow point is appropriate, while the motor is running current must not exceed the rated current. 3. Stop order: close the outlet piping of the valve - Motor - gauge Maintenance: 1. should always check whether the pump is running smoothly, without mechanical seal wear and leaks, and timely replacement of seals to prevent water from entering the motor pressure . 2. Always check the temperature of the motor housing, the maximum temperature should not exceed 85 ℃, the temperature is too high if found, should immediately stop checking. 3. When the pump a long time out, you should drain the water, go rust scale, painted with anti-rust oil for the next reuse. Pump Common Troubles and the failure of the primary reasons Symptom Remedy pump does not rotate 1, line 2 unreasonable or incorrect wiring, fuse burned 3, 4 motor damage, jammed impeller 1, repair power lines 2, replace the fuse 3, the repair 4 , toggle flexible blades turn the pump shaft can be rotated but supply a dry, water is less than 2, inlet pipe leak 3, 4 high suction impeller damage 5, 6 speed is too low, the pump reverse 1, re-injection, injection Man 2, check the pipeline, with a sealing material 3, adjust the suction or more suction pumps 4, replacing the impeller 5, check the motor damage, the voltage is too low. 6, rewiring less water 1 pump have Air 2, the radial clearance between the impeller inlet ring at large that pump water backflow 3, line 4 partial blockage, low voltage, resulting in decreased speed 1, check the leak site, to seal 2, the replacement of worn impeller 3, 4 shutdown to clean and stable power supply voltage leakage 1, damaged seals 1. Replace seals (seal or O-ring) is not enough pressure 1 outlet road resistance loss too 2, the output pump rated head height greater than 1, shortening or an increase in the diameter of the pipe 2, re-purchase for the Water Pump vibration or noise 1, 2 pump is not securely installed, the inlet pipe leaks or inlet port extends into water deep enough, the air sucked into the pump. 3, the pump impeller cavitation 4, the pump operating point deviation from the normal operation 1, connections and support strengthening the pump site 2, with a sealing material or seal leak at maturity plus water depth of 3 drowned, reduce or increase the pump mounting height inlet diameter or increase the intake pressure and replace damaged impeller 4, try to adjust the pump is running at the rated point and pump high efficiency area, avoid running the pump at high flow point the motor heat burned noisy 1, ambient temperature is too high, the motor cooling efficiency 2, the motor load is too heavy, overloaded pump running 3, the voltage is too high or too low or phase 4, the motor inlet 5, the unit is not securely installed 6, the motor turning right. 1, to improve the working environment pump, check the fan is normal, duct clogging 2, pump has stuck phenomenon, downtime; or the bearing is damaged, replace the same specification models bearing; or larger pump flow operation, adjusting pump rated point and area of ??operation of the pump high efficiency, or fluid medium concentration of big 3, rated supply voltage 4, disassemble maintenance drying, prevent water from entering the motor shaft hole 5 from the gap at the junction box and tighten the pump each supporting parts 6, rewiring, change the direction.
