Abstract
The utility model provides an underflow pump, belonging to the field of the pump. The underflow pump is provided with a machine frame, the middle position of the machine frame is connected with a cleaning water tank, and one end of the machine frame is connected with a sucking and discharging device. A material cylinder is connected between the cleaning water tank and the sucking and discharging device, and the other end of the cleaning water tank is connected with a main cylinder. The sucking and discharging device comprises a bunker, a discharging oil cylinder, a sucking oil cylinder and a sucking valve, the bunker is positioned at the upper side of the machine frame, and the upper end of the bunker is connected with the sucking oil cylinder. One end of the sucking oil cylinder is connected with the sucking valve, the side surface of the bunker is connected with the discharging oil cylinder, and the end of the discharging oil cylinder is connected with a discharging valve. The underflow pump has the advantages of simple structure, convenient maintenance, difficult damage, high reliability and good sealing performance, the sucking and discharging valves adopt the conical valve structure, and the opening and closing of the valve can be finished by a hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of underflow pump.
Background technique
At present, the pumping underflow all adopts diaphragm pump to finish basically, and diaphragm pump mainly partly is made up of motor, speed reducer, connecting rod, piston, piston cylinder, barrier film, the pump housing, suction pellet valve, hydraulic system etc.During work, the motor drives connecting rod will rotatablely move and convert the straight line motion of piston to, an airtight hydraulic pressure cavity is arranged between piston and barrier film, by hydraulic system hydraulic pressure cavity is filled with hydraulic oil, promote the barrier film evagination by hydraulic oil during piston-advance, slurry is sent the pump housing, when piston retreats, the hydraulic pressure cavity internal pressure reduces and forms parital vacuum, the barrier film indent, and outside slurry enters the pump housing by the suction ball valve.Diaphragm pump relies on the evagination of barrier film and indent to realize suction, discharge by suction, discharge ball valve, complex structure, and difficult in maintenance, barrier film is easy to breakage under the effect of alternating force, in case and the barrier film breakage, cause the dual pollution of slurry and hydraulic oil; Suction, blow-off valve adopt ball-valve structure, and valve seat is easy to damage, change barrier film, valve seat difficulty during maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of: underflow pump simple in structure, easy to maintenance.
The purpose of this utility model be this realize: this underflow pump has a frame, be connected with the cleaning water tank in the intermediate portion of frame, end in frame is connected with suction, material discharge device, be connected with the material cylinder cleaning between water tank and suction, the material discharge device, be connected with master cylinder at the other end that cleans water tank.
Suction, material discharge device are made of hopper, discharge oil cylinder, suction oil cylinder and material sucking valve, hopper is positioned at frame top, is connected with the suction oil cylinder in the hopper upper end, is connected with material sucking valve at an end of suction oil cylinder, be connected with the discharge oil cylinder in the hopper side, be connected with blow-off valve in the end of discharge oil cylinder.
Beneficial effect: owing to adopt such scheme, the intermediate portion of underflow pump frame is connected with the cleaning water tank, end in frame is connected with suction, material discharge device, be connected with the material cylinder cleaning between water tank and suction, the material discharge device, be connected with master cylinder at the other end that cleans water tank, simple in structure, be convenient to maintenance, reached the purpose of this utility model.Advantage: simple in structure, easy to maintenance, inhale blow-off valve and adopt cone valve structure, the unlatching of valve, close by oil hydraulic cylinder and finish, not fragile, reliability height, good seal performance.

Fig. 2 is the plan structure figure of Fig. 1.
Fig. 3 is the side-looking structural drawing of Fig. 1.
Embodiment
Embodiment 1: this underflow pump has a frame 1, be connected with cleaning water tank 3 in the intermediate portion of frame 1, end in frame 1 is connected with suction, material discharge device, be connected with material cylinder A4 and material cylinder B9 between water tank 3 and suction, the material discharge device side by side cleaning, be connected with master cylinder A2 and master cylinder B8 side by side at the other end that cleans water tank 3.
Inhale, material discharge device is by hopper 5, discharge oil cylinder A7 and discharge oil cylinder B11, suction oil cylinder A12 and suction oil cylinder B14, material sucking valve A13 and material sucking valve B15 and blow-off valve A6 and blow-off valve B10 constitute, hopper 5 is positioned at frame 1 top, be connected with suction oil cylinder A12 and suction oil cylinder B14 in hopper 1 upper end, end correspondence at suction oil cylinder A12 and suction oil cylinder B14 is connected with material sucking valve A13 and material sucking valve B15, be connected with discharge oil cylinder A7 and discharge oil cylinder B11 in hopper 5 sides, be connected with blow-off valve A6 and blow-off valve B10 in the end correspondence of discharge oil cylinder A7 and discharge oil cylinder B11.
During work, master cylinder A2 advances, and master cylinder B8 retreats simultaneously, and suction this moment oil cylinder A12 drives material sucking valve A13 and closes, and suction oil cylinder B14 drives material sucking valve B15 and opens; Discharge oil cylinder A7 drives blow-off valve A6 and opens, discharge oil cylinder B11 drives blow-off valve B10 and closes, material cylinder A4 communicates with discharge gate and carries out discharge, discharge gate is between discharge oil cylinder A7 and discharge oil cylinder B11, material cylinder B9 communicates with material sucking port and carries out suction work, and material sucking port is between suction oil cylinder A12 and suction oil cylinder B14; When master cylinder A2 advance put in place after, control system is sent signal, the hydraulic oil trend converts master cylinder B8 to and advances in the controlled hydraulic system, and master cylinder A2 retreats, suction this moment oil cylinder A12 drives material sucking valve A13 and opens, suction oil cylinder B14 drives material sucking valve B15 and closes, and discharge oil cylinder A7 drives blow-off valve A6 and closes, and discharge oil cylinder B11 drives blow-off valve B10 and opens, material cylinder A4 communicates with material sucking port and carries out suction, and material cylinder B9 communicates with discharge gate and carries out discharge.So circulation just can be finished the pumping work of slurry.
The pumping solid content is not more than 70% various water-based slurries, oil base slurry and chemical industry slurry.This pump discharge pressure is not more than 25MPa, and this pump adopts two master hydraulic cylinders to drive two material cylinders.Four times oil hydraulic cylinder drives suction material spool, finishes the work of suction material by the sequence of movement of six oil hydraulic cylinders of PLC control.
