Regular section miniature diaphragm pump

Miniature diaphragm pumps are mainly used in centrifugal pumps do not have self-priming function, widely used in general industrial equipment, pharmaceutical equipment, chemical equipment, ships, beverages, carpeting and floor cleaning, water purification and water treatment equipment, vehicle cleaning, agricultural spray , Pipeline pressure, air-conditioning cooling, coal metallurgy industry

Model Description:

Y type: with pressure switch

Features: Pump outlet closed or plugged, the pipeline pressure increases, when the pressure switch to set the value automatically cut off the power to stop the motor; re-open the outlet pressure to reduce the pressure switch automatically turns on the power, the motor running.

Scope of application: car washing machine, automatic solar water system, water system automatic control or other fluid automatic control auxiliary equipment.

H type: with return valve

Features: When the water outlet of the pump is closed or blocked, when the pressure of the pipeline increases to the set value, the return valve is opened and the water flow circulates in the pump cavity, the motor is always running; therefore, the requirement for the size of the water outlet is not high and the adaptability is strong

Scope of application: high pressure spray equipment, agricultural spraying and other applications that require high pressure fog

4, instructions for use

1) Connect the pump to the inlet and outlet pipes: Ensure that the inlet and outlet pipes are connected to the pump tightly, otherwise it will cause low pressure or leakage;

 Tip: There are arrows on the pump cover indicate the direction of water inlet and outlet, the direction of the arrow is water, on the contrary, water;

2) In the water inlet to install the filter, the filter density required in the best 80 mesh or more (that is, a small square of 80 holes)

3) The micro-diaphragm pump connected to the power supply: the electrical parameters of the power supply must meet the input requirements of the motor;

4) Turn on the power, the motor pump starts running;

5) water for 5-10 seconds, drained the air inside the pump and pipeline, and other water stable, temporarily turn off the power, connected to the water gun (or similar tool);

6) Turn on the power to work properly.

5, the use of precautions

1) Do not use hot water or dirty water with a temperature above 60 ° C (dirty water in the sand will cause irreparable damage to the pump);

2) Motor pump can reduce splashed a small amount of water (to be dry after use), can not directly facing the motor pump water, the motor pump is prohibited in the water;

3) motor pump can not be placed in a humid place for a long time;

4) Do not disassemble the machine or adjust the pressure setting screws by yourself. (Adjust the pressure setting screws without authorization, which may be fatal to the pump).

5) It is forbidden to use the machine without connecting the filter. The best filter density is more than 80 meshes (impurities will cause damage to the pump).

6) The diameter of the spray hole must meet the specified value, otherwise the motor pump will be damaged (see Table 1 for details);

7) household only, not for commercial use (to avoid overheating and reduce the service life, if possible, the conditions recommended intermittent work);

8) Please confirm the power supply before use, the power supply parameters should be consistent with the motor pump input parameters (see Table 1);

9) It is recommended that the matching power cord be not thinner than 0.75 square (copper wire) and the length should be about 2.5 meters. If you really need to lengthen, you need to lengthen the diameter of the bold at the same time, otherwise it will be due to the power line pressure drop is too large, resulting in reduced output performance of the motor pump (the thicker the better, the shorter the better, the length can be enough) ;

10) It is recommended that the inner diameter of the outlet pipe should not be less than 5.5, and the length should not exceed 10 meters (not too long and too fine, otherwise it will affect the pressure flow and the effect of the gun.) The thicker the better, the shorter the better.

11) It is recommended that the inlet pipe diameter is not less than 6, the length of the inlet pipe should not exceed 1.5 meters when taking water (the thicker the better, the shorter the better, enough for it)

12) Tap water and other pressure sources, you can properly lengthen the inlet pipe, water pressure should not exceed 0.2MPA (2 kg force)

13) In winter, after use, it is necessary to drain the water in the pump and the pipe, otherwise it is easy to freeze the pump;

14) 220V mains power supply, the power adapter connected to the power circuit must be equipped with earth leakage protection;

15) When the power cord is damaged, please carry out maintenance or replacement by professional personnel.

16) Battery power supply, beware of battery power loss;

17) Disconnect the motor pump and the power supply when not in use for a long time or suspended.
