high performance brushless diaphragm pump with PWM adjustable speed
pumps are used in many industrial and scientific processes including composite plastic moulding processes, production of most types of electric lamps, vacuum tubes, and CRTs where the device is either left evacuated or re-filled with a specific gas or gas mixture, semiconductor processing, notably ion implantation, dry etch and PVD, ALD, PECVD and CVD deposition and so on in photolithography, electron microscopy, medical processes that require suction, uranium enrichment, medical applications such as radiotherapy, radiosurgery and radiopharmacy, analytical instrumentation to analyse gas, liquid, solid, surface and bio materials, mass spectrometers to create a high vacuum between the ion source and the detector, vacuum coating on glass, metal and plastics for decoration, for durability and for energy saving, such as low-emissivity glass, hard coating for engine components (as in Formula One), ophthalmic coating, milking machines and other equipment in dairy sheds, vacuum impregnation of porous products such as wood or electric motor windings, air conditioning service (removing all contaminants from the system before charging with refrigerant), trash compactor, vacuum engineering, sewage systems, freeze drying, and fusion research. In the field of oil regeneration and rerefining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. Especially in the field of transformer maintenance, vacuum pumps play an essential role in transformer oil purification plants which are used to extend the lifetime of transformers in the field.
adjustable speed pump's parameter and features
mini pump has the following advantages:
compact structure, maintenance free
oil free,low power consumption, corrosion resistance
high pressure,high flow, low noise
long life and other characteristics
Our company offers multiple component configurations allowing pump to be used for either vacuum operation, pressure operation, or alternating vacuum and pressure operations.The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliable, highly efficient.
Its flow can deliver up to 3 L/min and 18L/M.
Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V .
When you choose pump, you can tell me the pump's voltage you need.
We can do it for you.
You can choose pump according to our model.
In addition,it can be mounted in any position.
Special requirements for materials about adjustable speed brushless pump
All materials comply with environmental standards.
Motors comply with EMC.
pump material is nonflammable or any fire should be fully extinguish within 30
seconds under 10 seconds of ignition test.
environmental testing requirements about adjustable adjustable speed pump
|Number||Item||Test conditions and requirements||Remarks|
|1||Steady-state heat and wet||60%rh||High humidity can affect the electrical performance of the motor|
|2||Temperature Shock||The pump was placed at -20 ℃ environment ,after 1h immediately placed at + 70 ℃ ± 3 ℃ environment for 1h.This is for 1cycle. After 50 cycles was returned to room temperature.0.5h later,pumping power test is conducted. The pump should be able to work properly; fasteners should not loose , in working condition pump’s body should not be leakage when block pump’s outlet.||too high temperature affect pump’s parameters, life and electrical performance|
|3||High temperature test||Pump is at 70 ℃ ± 3 ℃ environment for 48h. Then take it out. After 0.5hours later, at room temperature power pump. Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change.|
|4||Low temperature test||For 72 hours,pump is at -20 ℃ environment. Then take it out. Power the pump and test it.( when testing the pump,pump’s body can not have ice ). Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change.||In too low temperature,motor cannot be started
Electrical Performance about adjustable speed pump
10MΩ / between wire and frame measurements , 500VDC / min
|2||Dielectric strength||5mA Max/between wire and frame measurements 500 VAC/min
adjustable speed pump's dimension
Unlabeled tolerance is ± 0.1mm.
Outlet:OD 5mm, silicone hose suggestion:ID 3.5mm
Materials:pump body: PC/PPS, diaphragm: EPDM
Because we use imported ball bearing,the pump’s performance is stable and high.
The membrane is made by EPDM and pump's body is made by special PC/PPS which make pump well endurance and strong chemical resistance.
External PWM speed control principle
1, control board wiring diagram:
2, external use PWM speed control principle:
Description: 1, the external PWM signal by a small MOS tube or after the transistor processing, received a speed adjustment (such as above).
2, the frequency of PWM signal can be adjusted by 100HZ-1KHZ, and the change of speed regulation 0-6V can be realized by adjusting the duty ratio.. When the duty cycle is 100% (i.e., total height), the speed regulation is 0V, and the time ratio is 0 (i.e., the total low), the speed regulation is 6V, and the speed is at full speed.
