Embodiment Construction
[0026] see figure 1 and figure 2 , The motor 1 of the present invention is installed on the motor bracket 2, and is connected to the central shaft 17 through a transmission mechanism, and the eccentric disc 18 is mounted on the central shaft 17. A plurality of working cylinders 8 are radially and evenly distributed on a base 10 along the circumference. The piston push rod 23 end of each working cylinder 8 faces the center and is connected to the roller 13 through the roller bracket 12. Each roller 13 In contact with the peripheral surface of the eccentric disc 18, the roller frame 12 is installed on the slideway of the upper plate 11 of the base. The upper and lower ends of the central shaft 17 are rotatably supported between the base 10 and the motor bracket 2 through upper and lower centering discs 20 and 21 respectively. The inlet of each working cylinder 8 is connected to the low-pressure pipeline 28 through a water supply valve box 7 and the low-pressure valve 26 respe...

Disclosed is a disc-type multi-cylinder slime pump. A motor thereof is mounted on a motor bracket and connected with a central shaft via a transmission mechanism, and an eccentric disc is mounted on the central shaft; a plurality of working cylinders are mounted on a base equispacedly along the circumference in a radial direction, the end of a push rod of each working cylinder is directed towardsthe center and connected with rollers via a roller frame, and each of the rollers contacts the circumference surface of the eccentric disc; the inlet of each working cylinder is connected with a valveand a low-pressure pipeline respectively via a water inlet valve box, and the outlet of each working cylinder is connected with the valve and a high-pressure pipeline via a drainage valve box. The invention effectively improves the stability of pressure in operation and prolongs the service life; working cylinders can be maintained or changed without stopping the pump, thus drilling speed can bemultiplied, one pump can achieve the function of two pumps, energy is saved, consumption is reduced, drilling cycle is shortened, and cost of drilling engineering is lowered. The invention is an up-to-date and ideal equipment for drilling engineering.
Description
technical field [0001] The invention relates to a disc type multi-cylinder mud pump. It belongs to the construction equipment of oil drilling engineering. Background technique [0002] There are many types of mud pumps for existing oil drilling, which are divided into double action and single action according to the working state, and divided into two cylinders and three cylinders according to the number of working cylinders. But the basic structure is reciprocating. The driving method is the bellcrank structure, and the disadvantages are: [0003] 1. The number of cylinders is small, the wave peak is high, and the pump pressure stability is poor, so there must be an air bag to adjust; [0004] 2. Heavy weight; [0005] 3. The processing and assembly requirements are strict, and the assembly is difficult; [0006] 4. The service life of wearing parts is short, and the repairs are more difficult, and the pump must be stopped for repairs. Contents of the invention [0...
