Description

Revolvingly driven pumps charastised by no contact between transmission component and fluid

The utility model relates to the revolvingly driven pump that a kind of dirivig member does not contact with fluid, it mainly is the cushion that is coated by the annular orbit inboard, cooperate the roller in the central rotary seat, when rotary seat rotates, push cushion by roller, and can between cushion and annular orbit, produce a pull of vacuum, make fluid carry along annular orbit and cushion, and do not contact with any drive mechanism or parts, can be in order to carry various fluids of different nature.

Existing pump is of a great variety, wherein exhausted major part all can make the fluid that is transferred contact with dirivig member or piston etc., thereby can't apply to have the bigger fluid of rodent strong acid, highly basic or friction, otherwise very easily cause the damage of its dirivig member, thereby make the user when selecting pump for use, be subjected to multiple restriction.

In being seen on the market pump at present, can provide dirivig member not contact with conveyance fluid, the diaphragm type pneumatic pump is only arranged, this kind pump is that vibration diaphragm and the many group one-way valves in the utilization pressurized gas proportioning pump that air compressor provided comes convection cell to carry, though this kind structure can provide a conveying effect that does not contact with fluid, but it still must consider the runner material in its pump inside when utilization, because in this type of pump design, though its vibration diaphragm can allow drive gadget not contact with fluid, but being still with metal, makes its runner, that is in the delivery stroke of its convection cell, fluid is the runner of contact equivalent length (comprising that its one-way valve partly) in this kind pump still, thereby it the time still is subjected to many restrictions in utilization, if desire to carry more special chemical fluid with it, then its runner still has the possibility that weathers.

Can be learnt if further analyze then again, general membrane pump all is to cooperate air compressor to carry out work, thereby must have air compressor in the place of its utilization, otherwise just can't provide its suitable power, but air compressor is bulky, must be moved at any time, thereby the fixed position that this type of oscillatory type pneumatic pump mostly applies in the factory or pipeline disposes, and can't be moved utilization at any time according to user's needs, moreover, the price of air compressor itself is promptly quite high, if for the power of a pump is provided, and purchase an air compressor separately, the user is also caused meaningless economic burden, so existing pump has its improved necessity in fact.

This creator is because existing various types pump all can't provide preferable effect, be that some design can make its dirivig member contact with fluid and can't be in order to carry more special fluid, and some design must be subject to its power source and can't widely use, actively studied improvement, after constantly attempting and testing, developed the utility model of true tool practical effect finally.

Primary and foremost purpose of the present utility model is to use annular orbit to cooperate cushion, and carry out the conveying of fluid with the roller on the central rotary seat, thereby the equal and fluid isolation of the whole parts that can guarantee pump, and make fluid only flow at annular orbit and cushion intercropping, thereby can apply to the conveying of various special fluids, and unexpected fluid exerts an adverse impact to parts.

Another purpose of the present utility model is that its rotary seat drives with a rotatingshaft, thereby can cooperate various rotating power source to use, and it is convenient and much economical to use motor driven will cooperate an air compressor to move after all in various environment.

Another purpose of the present utility model is to simplify the overall structure of pump, and makes cost extremely low, and its each member all can be changed easily simultaneously, even partly member damages, also can change easily, seemingly not commonly use pump and can't keep in repair at all, scrap in case fault is promptly accused by the user.

A purpose more of the present utility model is its deft design, thereby various models can be arranged, and volume size arbitrarily can be made into size as the palm even, is beneficial to the user and settles utilization, even can portably use.Moreover, the utility model even can cooperate a joystick to drive its rotatingshaft, and can when needed it be carried, and when not having power, drive with manpower, as when automobile gasoline is used up, can utilize the utility model to extract easily, and need not inhale to such an extent that all be gasoline in one's mouth with siphon principle by water pipe.

The revolvingly driven pump that dirivig member of the present utility model does not contact with fluid, the annular orbit inboard is coated with one deck cushion, on the annular orbit of nearly cushion end position, be respectively equipped with access hole, and in annular orbit, be assembled with a rotary seat by the rotatingshaft drive, on rotary seat, be assembled with the rollers of many group compressing cushions;

Rotate by rotatingshaft driven rotary seat, make roller that cushion is pressed to the annular orbit inboard, partly then can produce a pull of vacuum thus by the elasticity pop into position of itself at the cushion of not pushed down, fluid is sucked by a side access hole, and by discharging in the opposite side access hole;

One side of annular orbit is provided with a breach, and be assembled with fixed base, fixed plate and two pressing plates in this indentation, there, extend a fixing bolt on this fixed base, and be provided with a perforation in being fixed in, it cooperates hold-doun nut to be assembled in the breach side of annular orbit, and the end clips of cushion is established between the breach that is fixed in pressing plate and annular orbit;

The annular orbit side is provided with the recessed edge of ring-type, and is provided with flange with matching in the cushion side.
