Problems solved by technology

Packing is an important sealing part in reciprocating pumps. The plunger reciprocates through the packing box. Due to the high-frequency reciprocating motion of the plunger, the packing will gradually wear out, affecting the sealing effect. In severe cases, even leakage accidents may occur
Therefore, the packing needs to be fastened in a timely manner, but at present, the packing is mainly fastened manually. The problems of the manual fastening method are: time-consuming and labor-intensive, high labor intensity, and poor fastening effect

Embodiment Construction

[0021] The specific implementation of the automatic packing tightening device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] For ease of description, the end of the connection mechanism close to the ratchet mechanism is defined as the "front end", and the end of the connection mechanism away from the ratchet mechanism is defined as the "rear end".

[0023] Such as figure 1 with figure 2 As shown, the automatic packing tightening device of the present invention includes: a ratchet mechanism and a driving mechanism for driving the ratchet mechanism. Wherein, the driving mechanism includes a connecting rod 1 connected with the power device. The ratchet mechanism includes a rocker 21 , a ratchet 3 hinged on the rocker 21 and a ratchet 4 engaged with the ratchet 3 . Such as image 3 As shown, the first end of the rocker 21 is provided with a connection hole 211, and the hinge shaft passes through the connectio...

Abstract

The invention discloses an automatic packaging fastening device. The automatic packaging fastening device comprises a plurality of ratchet mechanisms which are driven by a driving mechanism. The driving mechanism comprises a connecting rod connected to a power device. Each of the ratchet mechanisms comprises a rocker, a pawl hinged to the rocker and a ratchet wheel engaged to the pawl; the first end of each of the rockers is connected to the connecting rod and a hollow disc is fixed at the second end of each of the rockers; each of the ratchet wheels comprises a mounting end and a ratchet end, the mounting end is rotatably mounted in the hollow disc, the ratchet end is engaged to the pawl, and the ratchet wheel is fixedly connected to a pressing cap of a packing box. According to the automatic packing fastening device disclosed by the invention, the ratchet mechanisms are driven by the driving mechanism to drive the pressing cap to be screwed in a single direction, so that the packing is automatically compressed; the device is simple in structure, stable and reliable to work and convenient to mount and maintain, and automatic control and intelligent control are realized.

Description

technical field [0001] The invention relates to the field of pumps, in particular to an automatic packing tightening device, which can automatically tighten the sealing packing of a plunger pump. Background technique [0002] The existing plunger-type reciprocating pump has the advantages of high pressure, large flow, high volumetric efficiency, adjustable flow, stable and reliable operation, etc., and is widely used in various processes of oil production processes in oil fields, and is an essential and important equipment for oil production processes . Packing is an important sealing part in reciprocating pumps. The plunger reciprocates through the packing box. Due to the high-frequency reciprocating motion of the plunger, the packing will gradually wear out, affecting the sealing effect, and even leakage accidents may occur in severe cases. Therefore, the packing needs to be fastened in good time, but at present, the packing is mainly fastened manually. The problems of th...
