How does the diaphragm pump work
The pump is driven by an ac or dc motor
At the front of the motor is a valve assembly containing two valve pump cavities. Each chamber has a diaphragm behind it, located in the lower pump housing. As the motor shaft rotates, the internal CAM behind the diaphragm pushes the diaphragm forward, and then back in a continuous sequence, creating a suction. When this suction is formed, the fluid passes through the inlet and enters the outlet through various valve cavities
The flow rate is determined by several factors, including the number and size of the pump chamber, CAM offset, operating pressure, and fluid viscosity
Bojin 3206diaphragm pump USES the high quality of the permanent magnet motor, new materials, copper lines, more than 30 pump accessories are all made of high quality accessories, exquisite workmanship and complete testing equipment, standardized management, peers, repair rate is the lowest, perennial support related industry factory, the product quality is very good, through the European CE certification, ROHS certification, SGS certification, and exported to Europe, North America and other regions. Welcome friends from all walks of life to consult and cooperate regularly.
Bojin miniature dc diaphragm pump combines the advantages of self-priming and chemical pumps. It is made of imported corrosion-resistant materials. It is characterized by self-starting, 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. The products are of exquisite design, good quality and low price, and have properties such as oil resistance, heat resistance, acid and alkali resistance, corrosion resistance and chemical resistance. Pump body separated from motor, no mechanical parts, no wear.
The smart pump used by the car washing machine has its own pressure switch. As long as the water gun does not spray water, the water motor will not work, which not only saves water and electricity, but also avoids the loss of the machine.
The direction of the water outlet of the intelligent pump is divided into right and left water outlets.
1. Four features:
1. High pressure: generally up to 10Kg(only 5-6kg for similar products);
2. Small power consumption: only 4-5a.
3. Long service life: motor life is more than 5 years.
4. Corrosion resistance: the diaphragm is made of a variety of imported materials. It has properties of oil resistance, heat resistance, acid and alkali resistance, corrosion resistance and chemical resistance.
2. Technical indicators:
Power: 100 watts
Voltage: 12 v / 24 v
Maximum pressure :1.1mpa
General pressure: 0.8-0.9mpa
Maximum flow :8L/min
External size :180X100X70mm inspiratory distance is 1-3 meters, and the lift is up to 80 meters high.
1. The direction of the arrow on the pump is the exit.
2. The wire did not separate the positive and negative poles.
3. The pump can be placed in any direction.
Notes for use
Don’t soak in water.
2. Pressure adjustment screw cannot be adjusted at will. Before delivery, the pressure has been adjusted, such as arbitrary adjustment, reflux pressure easy to adjust, easy to burst water pipe.
3. Filter device must be installed at the entrance, and no impurities shall be entered. Otherwise, it is easy to block the pump, resulting in pressure drop or even no water.
V. common faults and troubleshooting
1. Electricity and pump do not rotate. Check the wire on the back of the motor.
2. The pump turns and sprays, but with less fog and less pressure. Open the pump and check if the pump chamber is blocked. If the motor bracket is loose, tighten the screw. Note that the inlet and outlet valves should not be reversed.
3. After half a year or a year, the pressure decreases and the spray volume is small. Open the pump and tighten the motor support screw; Change the upper and lower direction of the die in the cavity, or change the grinding plate.
Vi. Scope of use:
It is widely used in general industrial equipment, pharmaceutical equipment, chemical equipment, agriculture (lawn and garden), tourist vehicles, special vehicles, ships, beverage, automobile cleaning, carpet cleaning, ground cleaning, water purification and water treatment equipment.
Electric sprayers for agriculture production can also be changed into electric sprayers by hand pressure sprayers (to install mini pump directly on hand pressure sprayers, with batteries or hand lamp).
2. Water used for food, washing, bathing, toilets and flushing toilets for vehicles, boats, yachts and boats in use.
Food and beverage processing and processing equipment to realize liquid food delivery, distribution, filling, etc.
Household water supply. For example, water saving toilet, water saving toilet, electric toilet, water pipe pressurization system.
V. solar industry.
Water purification industry. For example, purification equipment, water treatment equipment, water fountains,
