Background technique
Transfer pump is in weaving, brewage, the all trades and professions such as chemical industry are used extensively, and of a great variety, at present, the conveying of slurry is mostly to adopt plunger pump or reciprocating pump, especially in textile industry, use general, one end of this type of transfer pump middle pump body is enclosed construction, form active chamber with plunger or piston, when plunger wherein or piston are to a lateral movement, when active chamber space is increased, in active chamber, form negative pressure, feed check valve is opened, and discharging one-way valve is closed, slurry is in feed check valve enters active chamber, when plunger or piston transfer to while moving to opposite side, active chamber space diminishes, produce working pressure, feed check valve is closed, discharging one-way valve opens, slurry transfers out through discharging one-way valve under the pressure of pump, the every to-and-fro motion of plunger or piston once like this, slurry is just exported once, that is to say, slurry is interrupted output, as want continuous operation, must be to adopt twin-tub or multi-cylinder to realize.But it is evident that, twin-tub or multicylinder pump complex structure, volume is large, and cost is high.
Model utility content
For the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to provide a kind of single-cylinder dual-action slurry transfer pump, it not only can realize with simplex pump the conveying of slurry, and can in a back and forth movement of piston, realize twice slurry and carry.
In order to solve the problems of the technologies described above, a kind of single-cylinder dual-action slurry transfer pump of the present utility model, comprise the pump housing, the piston matching with pump housing endoporus, described piston is separated into front active chamber and two active chambers of rear active chamber by pump housing endoporus, described front active chamber is connected with front feed check valve and front discharging one-way valve, described rear active chamber is connected with rear feeding one-way valve and rear discharging one-way valve, on described piston, be fixed with piston rod, this piston rod passes one end of the pump housing and is dynamically connected with this end sealed sliding.
In said structure, because described piston is separated into front active chamber and two active chambers of rear active chamber by pump housing endoporus, except the pump housing the same as the common pump housing is enclosed construction and forms active chamber with piston nose in piston nose, the pump housing is equally also enclosed construction at piston rear end, and forms active chamber with piston rear end.Again because described front active chamber is connected with front feed check valve and front discharging one-way valve, described rear active chamber is connected with rear feeding one-way valve and rear discharging one-way valve, front active chamber and rear active chamber all can be realized charging, compression, the work cycle of discharging, when piston moves from front to back, front active chamber space becomes the large negative pressure that produces, front feed check valve is opened under the effect of negative pressure, slurry is inhaled into front active chamber, and front discharging one-way valve is closed under the effect of negative pressure, now, front active chamber is in charging working state, meanwhile, rear active chamber space diminishes, produce working pressure, rear feeding one-way valve is closed under the effect of working pressure, rear discharging one-way valve is opened under the effect of working pressure, slurry under the pressure of pump through after discharging one-way valve transfer out, now, rear active chamber is in discharging state, when piston arrives rearmost position then by after while travelling forward,, active chamber is in charging working state, front active chamber is in discharging working state, like this, no matter piston is in proal state or the state in moving backward, there is the output of slurry, thereby realize twice slurry in a back and forth movement of piston, carry, again owing to being fixed with piston rod on described piston, this piston rod passes one end of the pump housing and is dynamically connected with this end sealed sliding, piston moves through piston rod transmission, the connecting rod that transmits piston movement in original technology is moved to outside the pump housing, avoided a difficult problem that is difficult to greatly sealing because of link motion scope between connecting rod and the pump housing of the rear active chamber of formation, straight reciprocating motion driven plunger by piston rod is carried out straight reciprocating motion, piston rod passes one end of the pump housing and is dynamically connected and has guaranteed the sealing effect of rear active chamber in piston rod working procedure with this end sealed sliding.
A kind of preferred implementation of the present utility model, described front feed check valve and rear feeding one-way valve are arranged in parallel; Described front discharging one-way valve and rear discharging one-way valve are arranged in parallel.Adopt this mode of execution, after front feed check valve is in parallel with rear feeding one-way valve, can be connected to same slurry source, after front discharging one-way valve is in parallel with rear discharging one-way valve, slurry can be transported in same materials pipeline, can make like this slurry in same slurry source be pumped into continuously in materials equipment, and pipeline jointing construction is succinct.
Another kind of preferred implementation of the present utility model, described piston rod and straight line movement driving mechanism are in transmission connection.Adopt this mode of execution, the transmission of piston rod is machine power transmission, and straight-line motion mechanism can be the connecting rod by motor-driven, also can be by motor reciprocating rotation, to be carried out the pinion and rack of transmission, can also be the driving mechanism of being realized by the piston movement of oil hydraulic cylinder or pneumatic linear actuator, these straight-line motion mechanisms all can be realized the continuous operation of transfer pump easily.
Another preferred implementation of the present utility model, described piston rod and described pump housing one end are dynamically connected by stuffing seal sealed sliding.Adopt this mode of execution, seal arrangement manufacture is simple, convenient filling, good sealing effect.
