How do diaphragm pumps work?
The pump is driven by AC or DC motors.
In front of the motor is a valve assembly containing two to five valve chambers. Behind each valve chamber there is a diaphragm located in the lower pump housing. When the motor shaft rotates, the internal cam located behind the diaphragm pushes the diaphragm forward, then pushes back in a continuous sequence, creating a suction. When the suction is formed, the fluid enters the outlet through various valve cavity check valves through the inlet.
The flow rate is determined by several factors, including the number and size of the pump chamber, cam offset, operating pressure, fluid viscosity garden type 12V 40psi self-suction pump battery-driven pump

BOJIN’s miniature DC diaphragm pump combines the advantages of self-priming pump and chemical pump. It is made of a variety of corrosion-resistant imported materials. It has self-priming function, thermal protection, stable operation, long-term continuous idling, long-term continuous load operation, small volume, small current, high pressure, low noise and long service life. With the advantages of exquisite design, good quality and low price, it has the properties of oil resistance, heat resistance, acid resistance, alkali resistance, corrosion resistance and chemical resistance. The pump body is separated from the motor, and there are no mechanical parts and no wear in the pump body.
The pump has its own pressure relief overflow circuit. Turn on the power supply, turn on the water switch, the pump starts to work; turn off the water switch, the pump continues to work, the liquid in the pump body began to automatically reduce pressure reflux, the pressure in the pipe will not increase, will not suffocate the pipe.
One, four characteristics:
1, pressure: generally can reach 4-6Kg
2, power consumption is small: only 1.4-2.4A.
3, long life: the life of the motor is more than 5 years.
4. Corrosion resistance: the diaphragm used is made up of a variety of imported materials. It has the properties of oil resistance, heat resistance, acid resistance, alkali resistance, corrosion resistance and chemical resistance.
Two, technical indicators:
Voltage: 6V12V 24V48V60V
Current: 1.4-2.4A or so
Maximum pressure: 0.6Mpa
General pressure: 0.3-0.4 Mpa
Maximum flow rate: 3L/min
Appearance size: 160X100X60mm
The maximum suction distance is 2 meters and the lift can reach 80 meters high.
Three, usage:
1. the direction of the arrow on the pump is the outlet.
2. wires do not divide the positive and negative poles.
3. pumps can be placed in any direction.
Four, use matters needing attention
1, do not soak in water.
2, pressure adjustment screws can not be adjusted at will. Before leaving the factory, the pressure has been adjusted, if arbitrarily adjusted, easy to adjust the pressure of reflux, easy to burst out of the water pipe. 3, the inlet must be installed with filtering devices, and can not enter impurities. Otherwise, it is easy to plug the pump, resulting in pressure drop or even no water.
Five, common failures and Troubleshooting:
1, electricity, pumps do not rotate. Check whether the wire behind the motor is falling off.
2. The water pump turns and sprinkled, but the amount of fog is small and the pressure decreases. Open the pump and check whether there is any blockage in the pump cavity. Whether the motor bracket is loose or not, tighten the screws.  Note that inlet and outlet valves can not be reversed.
3. After half a year or a year, the pressure decreases and the volume of spray is small. Turn on the pump, tighten the motor bracket screw; change the direction of the small die in the cavity up and down, or replace the small grinding plate.
Six, scope of use:
Vehicle cleaning, ship, beverage, carpet cleaning, floor cleaning, water purification and water treatment equipment.
One, the electric sprayer that produces agriculture uses, also can be changed into electric sprayer by hand pressure sprayer (install miniature water pump directly on hand pressure sprayer, match a battery or portable light can).
2. Water for food, washing, bathing, toilet and flushing of vehicles, ships, yachts and boats in use.
Three, food, beverage processing and processing equipment, to achieve the transfer of liquid food, distribution, filling and so on.
Four, family water supply. For example, water-saving toilets, water saving toilet, electric toilet, water pipe pressurization system.
Five, solar energy industry.
Six, water purification industry. For example, purification equipment, water treatment equipment, water dispenser, pure water machine and so on. It can be used for soft towel machine, water dispenser, Coke machine, juice machine, dishwasher, disinfector, solar energy bonsai, automobile glass washing and other production enterprises.
Seven. Other equipment and systems that require liquid transfer, injection and even metering. For example, garbage truck, sprinkler, carpet cleaning equipment, ground cleaning equipment, vehicle cleaning equipment, road construction equipment, dishwasher, medical equipment, chemical equipment, chemical equipment, chemical prevention equipment, disinfection equipment, cooling system, pressurization system, etc.
