Overview
One: main features of horizontal stainless steel pipeline pump
1. Smooth operation: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation and no vibration.
2. Drip water does not leak: Carbide seals of different materials ensure that there is no leakage in the transportation of different media.
3. Low noise: The pump under the support of two low-noise bearings runs smoothly. Except for the weak sound of the motor, there is basically no noise.
4. Low failure rate: The structure is simple and reasonable, and the key parts adopt international* quality matching, and the whole machine has no troubles working time.
5. Convenient maintenance: replacement of seals, bearings, easy and convenient.
6. The land occupation is more provincial: the exit can be left, right and up, and the pipelines are arranged and installed to save space.
Two: The main purpose of ISW horizontal pipeline pump
1. isw horizontal clean water pump for conveying clean water and other liquids with physical and chemical properties similar to clean water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire boosting, long distance transportation, warm Through the refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment, the use temperature t ≤ 80 ° C.
2, iswr horizontal heat pump is widely used in: metallurgy, chemical, textile, paper, hotels and restaurants such as boiler hot water pressurized circulation and urban heating system, iswr type use temperature t ≤ 120 °C.
3. IS WH type horizontal stainless steel pipeline pump for conveying liquids without corrosive and viscosity similar to water, suitable for petroleum, chemical, metallurgy, electric power, paper, food, pharmaceutical and synthetic fiber sectors. The temperature is -20 ° C ~ +120 ° C.
4, iswb horizontal pipeline oil pump, for transporting gasoline, kerosene, diesel and other oil products or flammable, explosive liquid, the temperature of the medium being transported is
-20 ~ +120 °C.
Three: horizontal stainless steel pipeline pump structure diagram
1. Test whether the motor is turning correctly. See the clockwise rotation from the top of the motor to the pump. The test time should be short to avoid dry wear of the mechanical seal.
2. Open the exhaust valve to fill the entire pump body and close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Move the pump by hand to allow the lubricating fluid to enter the mechanical seal end face.
5. The high temperature type should be preheated first, and the heating rate is 50 °C / hour to ensure uniform heating of all parts.
start:
1. Fully open imported valves.
2. Close the spout pipe valve.
3. Start the motor and observe if the pump is running correctly.
4. Adjust the opening degree of the outlet valve to the required working condition. If the user installs a flow meter or a pressure gauge at the pump outlet, the pump should be operated at the rated point listed in the performance parameter table by adjusting the opening degree of the outlet valve, such as the user. A flow meter or pressure gauge is installed at the pump outlet. The motor's current should be measured by adjusting the outlet of the outlet valve to make the motor run within the rated current. Otherwise, the pump will be overloaded (ie, operated at high current) to the motor. Burned out. Adjusted outlet valve opening is related to large and small pipeline conditions.
5. Check the leakage of the shaft seal. The leakage of the mechanical seal should be less than 3 drops/min.
6. Check the temperature rise of the motor and bearing at ≤70°C.
parking:
1. The high temperature type first cools down, the cooling speed is <10 °C/min, and the temperature is lowered to below 80 °C to stop.
2. Close the spout pipe valve.
3. Stop the motor.
4. Close the inlet valve.
5. If the vehicle is parked for a long time, the liquid in the pump should be drained.
The pump below 7.5kw can be installed directly on the foundation with the isolation pad.
When it is more than 7.5kw, it can be directly installed with the casting foundation. It can also be installed with the isolator of our unit is connected with the isolator, the installation method of the isolator is the size of the isolator matched with the isg pump, and the pump of the same specification in the isg series. The isolators are the same size.
Horizontal stainless steel pipe pump installation instructions
1. Before installation, check whether the fasteners of the unit are loose or not, and whether there is any foreign matter jam in the pump flow passage to avoid damage to the impeller and pump body when the pump is running.
2. The weight of the pipeline should not be added to the pump during installation to avoid deformation of the pump.
3. The anchor bolts must be tightened during installation to avoid the impact of vibration on the pump performance during start-up.
4. For the convenience of maintenance and safety of use, install a regulating valve on the inlet and outlet pipes of the pump and install a pressure gauge near the pump outlet to ensure operation within the rated head and flow range to ensure the normal operation of the pump and increase. The service life of the pump.
5. After the pump shaft is installed, the impeller should be free of friction or jamming. Otherwise, the pump should be disassembled for inspection.
6. The pump is divided into two types: hard joint installation and flexible joint installation (see connection method).
1.6mpa, pump static pressure test pressure is 2.5mpa, please indicate the system working pressure when ordering. Pump system working pressure is greater than
1.6mpa should be submitted separately at the time of ordering. In order to manufacture, the overcurrent portion and the coupling portion of the pump are made of cast steel.
2 Ambient temperature <40 ° C, relative humidity <95%. 3. The volume content of the solid particles in the medium to be transported does not exceed 0.1% of the unit volume, and the particle size is <0.2 mm.
