Embodiment 1

[0027] figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 with Image 6 The structure of the reciprocating four-cylinder mud pump of the present invention is given, including a slurry suction channel 1, a steel ball check valve 2, a plunger cavity 3, a slurry discharge channel 4, a double-ended stud 5, a cylinder head screw 6, and a bolt 7. , Plunger 8, box 9, sealing ring 10, linear bearing 11, liner 12, cylindrical pin 13, flat-bottomed follower 14, needle bearing 15, eccentric cam 16, deep groove ball bearing 17, cam support Shaft 18, box cover 19, bearing end cover 20, bearing cover 21, spherical roller bearing 22, center bearing cover 23, key 24, sleeve 25, coupling 26, drive motor 27, ball valve seat 28, steel The ball 29, the ball valve cover 30. As shown in the figure, the cam support shaft 18 is fixed in the bearing housing hole of the box 9, the output shaft of the drive motor 27 is connected to the cam support shaft 18 through a coupling 26 to realize movement a...

Embodiment 2

[0036] Such as Figure 7 Shown: The difference between this embodiment and the first embodiment is that the outer surface of the outer ring of the needle roller bearing 15 adopts a cylindrical surface and a plane combination design, and a hydrostatic oil chamber (not shown in the figure) is opened on the plane to roll The two parallel planes on the outer surface of the needle bearing 15 are directly matched with the corresponding planes of the flat-bottomed follower 14 to form a surface contact hydrostatic lubrication cam pair. The liner 12 is removed so as to be suitable for high-power and heavy-duty applications.

[0037] The operation process of the four-cylinder mud pump of the present invention is as follows: The power of the constant torque variable frequency speed regulating motor is directly input to the cam support shaft 18 through the coupling 26 and runs, and the four eccentric wheel cams 16 on the cam support shaft 18 drive The four flat-bottomed followers 14 push the...

Abstract

The invention provides a reciprocating four-cylinder slurry pump. The reciprocating four-cylinder slurry pump comprises four single-cylinder pump head systems, a flat-bottom driven part eccentric wheel type disk cam plunger driving system and an eccentric wheel type cam supporting and transmission system. Each single-cylinder pump head system is provided with a slurry suction channel, a slurry discharge channel, two steel ball one-way valves and a plunger cavity. Four flat-bottom driven part eccentric wheel type disk cam mechanisms are adopted for the plunger driving system. Plungers are fixedly connected with flat-bottom driven parts. The flat-bottom driven parts directly drive the plungers to conduct reciprocating motion. Four eccentric wheel type cams are evenly mounted on a cam supporting shaft in the eccentric wheel type cam supporting and transmission system at the interval of 90 degrees. The reciprocating four-cylinder slurry pump is compact in structure, light in weight, low in vibration and noise, convenient to maintain, high in mechanical efficiency and reliability and small in flow rate and pressure pulsation, and the cam supporting shaft is small in stress.

Description

Technical field [0001] The invention belongs to the technical field of mud pumps, in particular to a reciprocating four-cylinder mud pump. Background technique [0002] Mud pumps are equipment used for mud transportation and are widely used in mines, geological drilling, coal mines, railways, highways, water conservancy and hydropower, bridges, high-rise buildings, foundation reinforcement and other projects. Commonly used mud pumps are piston type or plunger type. Its structure includes a pump body and a power mechanism. The power mechanism drives the crankshaft to rotate, and the crankshaft drives the piston or plunger to reciprocate in the cylinder liner. The suction valve and the discharge valve Under the alternating action of the pressure, the purpose of pressing the mud is realized. According to the number of reciprocating mud pump cylinders, there are currently several types, such as single cylinder, double cylinder, three cylinder and five cylinder. According to the work...
