The specific embodiment

As depicted in figs. 1 and 2, the utility model chain type oil pump comprises power section 11 and host machine part, host machine part comprises body 1, main shaft 2, drive sprocket 3, chain 4, counterweight 9, sucker rod 6, upper stroke switch 7, lower stroke switch 8, upper stroke switch 7 and lower stroke switch 8 are installed on the body 1, power section 11 is installed on the body 1, the output shaft of power section 11 links to each other with main shaft 2 by shaft coupling 12, drive sprocket 3 is installed on the main shaft 2, chain 4 is meshed with drive sprocket 3, one end of chain 4 links to each other with counterweight 9, and the other end links to each other with sucker rod 6.Chain 4 is the identical smart roller chains of the double short pitch that is launched into in-line of two equal in length, specification.Lifting force difference according to oil pumper can be designed to one or more.The utility model is designed to two.In order to increase the distance between chain 4 and the body 1, can on the body 1 of each drive sprocket 3 below tiltedly, a lazy sprocket wheel 5 be installed.For the convenient stroke of regulating, can on body 1, fix a standpipe 10, upper stroke switch 7 and lower stroke switch 8 are installed on the standpipe 10, like this by upper and lower slip upper stroke switch 7/ lower stroke switch 8, can regulate the stroke of oil pumper.Oil pumper also comprises the chain oil supply system, the chain oil supply system comprises oil storage tank 81 and the oil supply pipe 82 that is installed on the body 1, and oil supply pipe 82 links to each other with oil pump 83, and body 1 top is provided with oil groove 84, oil supply pipe 82 feeds in the oil groove 84, has oil outlet 85 on the oil groove 84 directly over the chain 22.After starting oil pump 83, the oil in the oil storage tank 81 is sent in the oil groove 84 by oil supply pipe 82, gives chain 22 fuel feeding equably by oil outlet 85 then.

As shown in figures 1 and 3, power section 11 comprises motor 31 and speed changer 32, and motor 31 is common electric machines, and motor 31 oppositely starts after each stroke finishes all will stop again, promptly stops continually, starts.Motor 31 adopts Frequency Converter Control to start, and has under long start-up time and the less acceleration, and each parts such as protection motor 31, speed changer 31, chain 4, sucker rod 6 are not hit.

Speed changer 32 has two kinds of output speeds, and when electromagnetism or hydraulic controlled clutch 13 joints, the gearbox output speed is low speed (being used to the stroke of pumping); When electromagnetism or hydraulic controlled clutch 14 joints, the output speed of speed changer 32 helps improving oil yield efficiency like this for high speed (being used for the oil return stroke).Motor 31 slows down through speed changer 32 by electromagnetism or hydraulic controlled clutch 13/14 again, is passed to shaft coupling 12, drives main shaft 2 and rotates, and drive sprocket 3 drives chain 4 and pumps up and down.

Motor 31, hydraulic pressure or

electromagnetic clutch
