INSTALLATION AND USE INSTRUCTIONS UNDER WATER PUMP MANUFACTURERWater pumps have long become indispensable equipment in many families. But the installation and how to use the pump is not everyone know.
A new water pump factory always attach a copy of the document to guide the installation and use of water pumps, but it was little attention den.De use well water pumps, durable purposes sua may bom services offer material used to pump you know about the machine.
HOW TO USE.
I. Preparation before use.
1.Noi ground wire before use to prevent the risk of electrical shock in case of improper insulation. To avoid electric shock, be careful not to be waterproof power plugs.
                               
NOTE;
                                     
- The ground connection after a power interruption.
- Absolutely not connected to the gas pipeline because of the risk of explosion.
 
2. Avoid operating the pump in dry conditions and no water for the machine so that takes strength and motor may malfunction.
                                      
3. Only use the pump to pump water to pump other liquids. If you use the machine for other solvents such as benzene, acids, flammable liquids such as gasoline and other types of high viscosity, the risk of fire can occur, causing faults and reduce the strength of the machine.
                                   
4. Do not use a blanket or cloth to wrap up of the pump to avoid the cold because the machine could ignite.
                                   
5. Avoid using the machine in the blanks may be in direct sunlight or rain is wet, as this will reduce the strength of the machine and also the risk of electric shock.
                                
6. Avoid using the machine in places with hot or cold below -100C and 400C to 400C hot water. Strength of the pump can be reduced.
                                    
7. In case the machine placed in wells MACAT can be sucked into the water with sand filtration equipment required. This device prevents the propeller pumps are not rubbing sand scratches quickly, pressure pumping weakened and reduced water quality.
                                       
8. oscillator voltage to keep the level of 10% of the available voltage. Without the strength of the machine can be reduced.
II. What to check before giving up.
Place the pump as close as possible wellhead. Where to put away the well pump, the maximum distance of the nozzle from the well to the pump suction height is calculated. Decision height depending suck dry conditions.
 
  Height smoking
The maximum length of the nozzle
8m
3m
7m
14.5m
6m
26m
5m
37.5m
4m
49m
 
III. Installation instructions pump.
 
Choose where to place the machine how to then be able to facilitate inspection or repair.
Where to place the pump in a narrow space, the minimum distance between the pump and the walls are 30cm.
Use very little elbow to prevent water leakage à to reduce water resistance.
Cement embankment to the machine from being skewed after several years of use.
Pumps are not classified as self-priming, one-way valve should be installed at the bottom of the nozzle.
Measure the depth from the surface to the bottom of the well. Suction standard length is 8m.
Only use pipes with a diameter of normal standards.
IV. Operate.
Absolutely not operate without priming. Felt and broken blades will make the strength of the decrease.
V. Using the machine again after a long time.
                           
The engine can not run even after turning power. The cause may be dirt accumulation and freezing in the water is pumped.
In this case, turn off the power, use a screwdriver or similar tool screw holes in the back of the motor shaft several times. Then, the pump can operate as usual.
VI. Boot
Because these pumps are not subject to automatic pump priming, the boot should priming sequence each step:
- Open the lid and fill the hopper, hopper lid. The air in the syringe will be ejected.
- Before you power on the part of the country to open the exhaust valve.
- If priming but not yet, perhaps because even the air in the syringe. For air exit nozzle pouring in, switch on and off several times power.
- For pumps without separate switch, use the power plug on the wall or plug and unplug the power cord from the socket.

Experience select and use water pumps 

Pumps are an essential part of the water system of the family uses well water. In areas where tap water scarcity. It is also a need for the pump to suck up water and put the tank. However, buying the machine is not a simple matter for the first time to shop. Sửa máy bơm would like to share some information and composition of household water pump in Vietnam: Centrifugal pumps:
Structure;    A type consists of one motor to rotate the impeller centrifugal forces created dandruff bring water to the appropriate height. Vacuum Pump
constitute
 Vacuum Pump is designed to work with wheel alloys and active in working chamber is made the same material as the impeller, this product can be long-term operation of the water environment. But do not overdo it because this product working chamber lid is made of plastic susceptible to malfunction. Suitable for areas with erratic water, fire cause pump failure. The engine was designed speed 3000 v / p with high quality materials to very high efficiency, energy savingHow to install and use the pump;- Installation of water as close as possible. Be sure to mount, avoid vibration when operating the machine.- Machine mounted as close to the water as possible. When placed in water pipes factory, have noted in previous input assigned to the tube. On the tube diameter to the diameter of the holes right on the water and not be placed close to the horizontal hole.- Be sure to attach the primer system in accordance with the instructions of the machine.- For the pump to be placed into the lake bottom and should have mesh to avoid garbage, sludge clog - damaged machine.- Pipe fitting to the correct diameter of the pump, minimizing the folded piece, no lead pipes around which reduces the efficiency of the pump.- To ease the assembly and repair of pumps should be installed more junk into push and pull of the road- The pipe must be sealed in and out, all the leaks can harm the machine operation.- The voltage must be connected to the right, so fitting an automatic circuit breaker, power cord must match the load capacity of the machine and good ground connection.Want to buy a suitable pump, pay attention to the following points:- The height between the two tanks, water from the tank bottom to the water tank above.- The volume of each tank.- The location of the pump.After obtaining these factors, you select the type of centrifugal pump with a total height, smoking and high altitude appropriate discharge. Often a pump of 1.5 higher than the actual value is appropriate. For example, the height is 10 m, then select the type of pump has a height of about 13-15 m. If the tank is small, just the kind of small capacity pump and small water flow (m3 reservoir, only one type of 1/2 HP pump and a large number of revolutions - 2000 rmp or more), longer larger pumps can choose a larger capacity is sufficient.- The high water absorption: the height of the vacuum pump is, water from lakes, ponds, wells ... to the center of the pump impeller. Usually high practical use smaller write-in, so when installing the water as close as possible.- Altitude discharge: the height that the water pump can put up to be.- The rotational speed of the pump: the number of revolutions per minute, was listed as the rpm (round per minute).- Pump Power: Watt or recorded by HP (st) http://suadiennuochanoi.vn/
