Description
Technical field
The utility model relates to a kind of four cylinder slurry pump, belongs to the slurry pump technical field.
Background technique
Slurry pump is the equipment for slurry transportation, is widely used in the engineerings such as mine, geological drilling, colliery, railway, expressway, water conservancy and hydropower, bridge, tall building, foundation stabilization.Slurry pump commonly used is piston type or plunger type, its structure comprises the pump housing and power mechanism, drives crank up by power mechanism, and bent axle drives piston again or plunger moves reciprocatingly in cylinder sleeve, under the alternating action of suction valve and expulsion valve, realize the purpose of force feed mud.Press the cylinder number classification of pump, have at present single cylinder, twin-tub, three cylinders and five cylinders etc. to plant pattern, but do not have four cylinder slurry pump.
Fig. 1 and Fig. 2 have provided the structure of existing double cylinder slip pump, comprise pump head 1, in connect 5 and power mechanism.Piston 15 is installed in the pump head 1, and is provided with slurry intake channel 2 and pulp passage 4, slurry intake channel 2 and pulp passage 4 are arranged in parallel, and both height are identical, are positioned on the same level face, are provided with one-way valve 3 on slurry intake channel 2 and the pulp passage 4.Power mechanism comprises the driving mechanism (motor not shown in FIG. in motor and the casing 8, motor, pump head 1 and casing 8 are installed on the support), motor is connected with driving mechanism by the band transmission, the band transmission drives transmission shaft 10 by passive belt wheel 14 and rotates, in the passive belt wheel 14 clutch can be installed, transmission shaft 10 rotates by primary gear speed reducing driving belt dynamic crankshaft 11, two connecting rods 9 are installed on the bent axle 11, two connecting rods 9 are connected with crosshead 12 in casing 8 interior two clutch release slave cylinders respectively, crosshead 12 is connected with guide rod 7, guide rod 7 again with pull bar 6 in connect for 5 interior connections, piston 15 to-and-fro motion that pull bar 6 drives in the pump heads 1 are finished into slurry and pulp.Also be provided with on the pump head 1 and be with manometric air chamber 13.
Because the slurry intake channel 2 in the above-mentioned double cylinder slip pump pump head 1 is identical with the height of pulp passage 4, this is just so that the distance between slurry intake channel 2 and the pulp passage 4 is larger, piston 15 is between slurry intake channel 2 and pulp passage 4, also just increased the volume of pump head 1, this just needs to increase a guide rod 7, also make simultaneously pump head 1 must by in connect 5 and be connected with casing 8, the volume and weight of whole like this slurry pump is just larger.And the bent axle of existing double cylinder slip pump is cast, and weight is difficult for greatly producing and processing.The structure of one-way valve 3 as shown in Figure 3 on slurry intake channel 2 and the pulp passage 4, on spherical cap 16, by valve pin 18 seal ring 17 to be installed to form, spherical cap 16 moves up and down in the valve seat orifice of pump head 1 to be realized opening and closing, seal by seal ring 17 when closing, but seal ring 17 damages easily, lose seal action, need often to change.
Triplex mud pump and five cylinder mud pump structures and two cylinder slurry pump are basic identical, just increase the quantity of connecting rod on the quantity of clutch release slave cylinder and the bent axle in casing.Such as Chinese patent literature CN2004200174132 disclosed a kind of " five cylinder mud ", have five rod journals on its bent axle, a connecting rod is housed on each rod journal, five connecting rods respectively reach the pump head that links to each other by a crosshead and a cylinder body and link.Chinese patent literature CN2009101172451 discloses a kind of " horizontal multi-cylinder single-action reciprocating type piston mud pump ", the horizontal six cylinder single-action reciprocating piston mud pumps of its first mode of execution, six cylinder single-action reciprocating piston mud pumps are in series the first bent axle and second bent axle of adjacent triplex mud pump by bent axle spindle nose, bindiny mechanism, any one off-centre on the first bent axle turn and the second bent axle on the angle of any one off-centre between turning be 0 °～60 °; The horizontal nine cylinder single-action reciprocating piston mud pumps of the second mode of execution, nine cylinder single-action reciprocating piston mud pumps are in series the bent axle of adjacent three triplex mud pumps by bent axle spindle nose bindiny mechanism, and nine off-centre of the bent axle of three series connection turn along the circumferential direction and evenly distribute.
The larger flow oscillation that existing triplex mud pump exists and the problem of pressure surge, slurry pump adopts more clutch release slave cylinder can improve discharge capacity, but according to existing structure, the above slurry pump volume and weight of three cylinders is very large, and cost is high, transportation inconvenience.
Chinese patent literature CN2006101706991 discloses " a kind of disc type multi-cylinder slurry pump ", its a plurality of clutch release slave cylinders radially and being installed on the base of being uniformly distributed along the circumference, the piston push rod end of each this clutch release slave cylinder is rotationally connected towards the center and by turning rolls and roller, and each this roller contacts with the side face of an eccentric disc.According to the scheme of this slurry pump, can make four cylinder slurry pump, but clutch release slave cylinder adopts circle distribution, complex structure, precision prescribed is high, has equally the large problem of volume and weight.
