Abstract
The utility model belongs to the control technique field of pneumatic pump automatic operating, is specifically related to a kind of pneumatic pump automatic controller.Mainly comprise pneumatic pump and fluid pneumatic control valve, it is characterized in that described fluid pneumatic control valve connection control device, described controller pulls valve built with hand, and hand is pulled valve and connected the ball float fluctuated with water level by rocking bar.When ball float rises to high water level, conducting hand pulls valve, and fluid pneumatic control valve is opened, and pneumatic pump ventilation runs; Along with the operation of pump, water level decreasing, ball float also declines thereupon, and when dropping to low water level, the gravity of ball float is closed hand and pulled valve, cuts off fluid pneumatic control valve, makes pneumatic pump out of service.The utility model achieves the unmanned management that pneumatic pump runs; Whole device need not electricity consumption, safe and reliable and cost is low in inflammable and explosive environment; Easy to install.
Description
Technical field
The utility model belongs to the control technique field of pneumatic pump automatic operating, is specifically related to a kind of pneumatic pump automatic controller.
Background technique
In industries such as China's energy, chemical industry, coals, using in a large number take pressurized gas as the pneumatic pump such as diaphragm pump, pneumatic pump of power, and these instances disable use electric power, and this brings a difficult problem with regard to the control for pump.Use artificial valve opening, close the operation that valve carrys out control pump, waste manpower; If be just difficult to realize manual control in the place of remoter building site or danger; If pneumatic pump is used for the operating mode of unattended duty, also can operating even if water drains pump always, waste a large amount of energy.
Summary of the invention
In order to overcome the deficiency of the necessary manual control of pneumatic pump, the utility model provides a kind of control gear of automation, makes pump can identify high water level and low water level, reaches the change according to water level, the object of automatic turn on pump, termination of pumping.
Pneumatic pump automatic control device of the present utility model, by the change of ball float perception water level, thus controls the switch of pneumatic pump.Not only avoid the anhydrous idle running of pump, and save the manpower of part.
The utility model solves the technological scheme that its technical problem adopts: pneumatic pump automatic control device, comprise pneumatic pump and fluid pneumatic control valve, it is characterized in that described fluid pneumatic control valve connection control device, the airtight cavity of described controller pulls valve built with hand, and hand is pulled valve and connected the ball float fluctuated with water level by rocking bar.
Usually, the rocking bar place that described palm valve connects with ball float arranges corrugated sealing ring.
Described fluid pneumatic control valve is by tracheae connection control device.
Described palm valve adopts two-bit triplet plunger-type structure.
Device of the present utility model, when using, also comprises the component such as the different tracheae of the air filter known by this field, threeway, outlet pipe, suction sleeve, caliber.
This device runs like this: when ball float rises to high water level, conducting hand pulls valve, and fluid pneumatic control valve is opened, and pneumatic pump ventilation runs; Along with the operation of pump, water level decreasing, ball float also declines thereupon, and when dropping to low water level, the gravity of ball float is closed hand and pulled valve, cuts off fluid pneumatic control valve, makes pneumatic pump out of service.
Compared with prior art, the utility model tool has the following advantages:
The utility model achieves the unmanned management that pneumatic pump runs; Whole device need not electricity consumption, safe and reliable and cost is low in inflammable and explosive environment; Easy to install.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment installs connection schematic diagram (in figure, pneumatic pump is for membrane pump with pneumatic drive); Fig. 2 is that embodiment's high water level work Time Controller inner float ball and hand pull valve phase diagram; Fig. 3 is that embodiment's low water level termination of pumping Time Controller inner float ball and hand pull valve phase diagram.
In figure: 1-air filter, 2-threeway, 3-fluid pneumatic control valve, 4-outlet pipe, 5-pneumatic pump, 6-suction sleeve, 7-φ 6 tracheae, 8-φ 8 tracheae, 9-φ 4 tracheae, 10-ball float, 11-hand pull valve, 12-controller.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
Embodiment: pneumatic pump automatic control device, mainly comprise pneumatic pump 5 and fluid pneumatic control valve 3, its main feature is fluid pneumatic control valve 3 connection control device 12, and controller 12 pulls valve 11 built with hand, and hand is pulled valve 11 and connected the ball float 10 fluctuated with water level by rocking bar.
As shown in Figure 1, whole device connects by this figure, and controller 12 is placed under water.What hand pulled valve 11 employing is two-bit triplet plunger-type structure, is connected with fluid pneumatic control valve 3 by φ 6 tracheae; Connected with threeway 2 by φ 8 tracheae; By the exhaust when commutating of φ 4 tracheae.When water level rises, ball float 10 rises thereupon, when reaching high water level, the plunger that the buoyancy of ball float 10 pulls hand to pull valve 11 by coupling rod moves upward, and when reaching the state as Fig. 2, pressurized gas are connected by φ 6 tracheae and fluid pneumatic control valve 3, fluid pneumatic control valve 3 is opened, and pneumatic pump 5 is started working.Along with the operation of pump, water level constantly declines, ball float 10 declines thereupon, when reaching low water level, the plunger that the gravity of ball float 10 pulls hand to pull valve 11 by coupling rod moves downward, and the pressurized air now in confined space is discharged by φ 4 tracheae, when reaching the state as Fig. 3, pressurized gas are cut off, and fluid pneumatic control valve 3 cuts out, and pneumatic pump 5 quits work.
Controller 12 in embodiment; consider presumable various foreign material in water; hand being pulled valve 11 is placed in an airtight cavity; avoid the function of the pollution effect valve of water body; ball float 10 extends, and ball float 10 and hand are pulled between valve 11 and connected by rocking bar, and ball float rocking bar place arranges special corrugated sealing ring; do not affect the function sent out when valve rod is shaken, hand can be protected again to pull valve member.
