Installation instructions 1. Installation of pipe weight should not be added to the pump, should have their own support, so as not to affect the deformation and operational performance life. 2. Pump and motor is the overall structure, no need to find the correct installation, so the installation is very convenient. 3. The installation must be tightened anchor bolts, so as to avoid the impact of vibration on pump performance when starting. 4. Before installing the pump should be carefully checked whether there is any impact on the pump runner pump hard material (such as stones, iron particles, etc.), so as to avoid damage to the pump impeller and pump body. 5. For maintenance convenience and safety, install a regulating valve on the inlet and outlet of the pump and install a pressure gauge near the pump outlet to ensure the operation within the rated head and flow range, to ensure the normal operation and growth of the pump The life of the pump. 6. Pump suction stroke occasions should be equipped with the end of the valve, and the inlet pipe should not have too many corners, at the same time not have leakage, leakage phenomenon. 7. Discharge pipe, such as check valve should be installed outside the gate valve. 8. Turn the pump shaft after installation, the impeller should have friction sound or stuck phenomenon, otherwise the pump should be disassembled to check the reason. 9. Pump installation is divided into rigid connection and flexible connection installation. Starting and parking (i) Preparation before starting 1. Turn the motor fan blades by hand, the impeller should be no card-grinding phenomenon, flexible rotation. 2. Open the inlet valve, open the vent valve to allow the fluid to fill the entire pump chamber, and close the vent valve. 3. Hand pump pump so that the lubricating liquid into the mechanical seal face. 4. Move the motor to determine the steering is correct. (Ii) start and run 1. Fully open the inlet valve, close the discharge pipe valve. 2. Turn on the power, when the pump reaches the normal speed, then gradually open the valve on the discharge pipe and adjust to the required conditions. 3. Observe the instrument readings, check the shaft seal leakage, the normal mechanical seal leakage, <3 drops / min, check the motor, the bearing temperature ≤ 70 degrees C, if abnormal circumstances should be promptly addressed. (Iii) parking 1. Gradually shut down the valve discharge pipe, cut off the power. 2. Close the inlet valve. 3. If the ambient temperature is below 0 degrees C, the pump liquid should be depleted to avoid cracking. 4. If the long-term disabled, the pump should be disassembled and cleaned, packed and stored. Pump maintenance and care (i) Maintenance and care during operation 1. The water line must be highly sealed. 2. Prohibit long-term operation of pump in cavitation. 3. Prohibit the pump running in the flow, the motor over-current long-term operation. 4. Regular check pump operation, the motor over-current long-term operation. 5. The pump should have someone in charge of the operation, in order to avoid accidents. 6. The pump should operate for 500 hours of running time for refueling. Motor power is greater than 11KW with a refueling device, high pressure gun can be injected directly to ensure excellent bearing lubrication. 7. Long-term operation of the pump, due to mechanical wear, so that the unit noise and vibration increases, the parking should be checked, if necessary, replace the vulnerable parts and bearings, unit overhaul period is generally one year. ⑵ mechanical seal maintenance and repair 1. Mechanical seal lubrication should be clean without solid particles. 2. It is forbidden to work mechanical seal under dry grinding condition. 3. Before starting the pump (motor) should be circled several times, so as not to cause a sudden start breaking seal ring damage. Tubing Loss Reference Table Valves and Tubing Equivalent Straight Pipe Length (each) Fully Open Gate 12 Unopened Double Standard Elbow 25 Check Valve 100 Bottom Valve 100 Partially Clogged Doubled NOTE For example 100mm diameter tubing, bottom valve closure 100 Times the diameter to 100 × 100 = 10000mm = 10m diameter length, assuming that the flow rate of 8L / S check the table, straight pipe per 100m loss of 1.3m, the loss of head 0.13m. A certain pipe diameter of the maximum flow limit.
Portable power station is a kind of portable power device with lithium ion battery. It can store electric energy and provide AC output. It is suitable for various outdoor activities.
Portable power station has the features of light weight, large capacity, large power, and easy to carry. It can be used indoors and outdoors. It usually provides 220V AC output, and is equipped with 5V, 9V, 12V and other DC output modules, widely used in home, office, photography, tourism, medical, emergency rescue and other fields. With the popularity of outdoor activities and the growth of outdoor equipment, the demand for outdoor power is also increasing. It can not only charge electronic devices such as mobile phones and cameras, but also be used for on-board products and low-power home appliances in self-driving trips.
When choosing a portable power station, the main considerations include capacity and output power, which determine how long the power supply will be used and the type of device supported. In addition, the charging method is also an important consideration, which is divided into mains charging and solar charging. The type of battery is also key, and lithium iron phosphate batteries are recommended for their high safety and long service life. Finally, charging noise is also a point that is easily ignored, and choosing a power supply with a charging noise of less than 30dB can be used quietly at night.
