Piston and pressure cylinder section of thick bamboo tip contact have become mechanical spacing, in order to prevent that the piston from assaulting pressure cylinder section of thick bamboo tip, add the blotter at the piston tip, prevent to assault the mechanical fault who arouses, have increased the work efficiency of compression medium simultaneously, maximize medium flow.
Description
Technical Field
The utility model relates to a gaseous booster pump technical field especially relates to a floating piston for gaseous booster pump.
Background
For the gas booster pump, traditional extremely poor piston is mechanical fastening connection with the piston rod, the axiality of piston and the cylinder of contact is the difficult problem of processing assembly always, piston and piston rod that the centering is not good still can produce the eccentric wear to the cylinder, the partial wear of cylinder and piston seal has been aggravated, leakage quantity has been increased, make the performance index decline of gas booster pump, still can lead to cylinder and piston strain in actual production, piston rod and piston seal assembly wearing and tearing, the unit produces aspects such as vibration. Due to uneven stress, even the extremely bad piston is sheared off or the piston rod is broken off, which causes great accidents. Meanwhile, the product has high failure rate, the production efficiency is influenced, and the maintenance cost is greatly improved.
When the traditional piston rod and the piston move repeatedly in the cylinder barrel, mechanical limit can be set in the set stroke range, the piston is prevented from impacting the end part of the cylinder barrel, and the piston and the end part of the cylinder barrel generate gaps, so that a medium cannot be compressed to the maximum extent.
SUMMERY OF THE UTILITY MODEL
The utility model provides a floating piston for gas booster pump to solve the above problems.
In order to solve the technical problem, the technical scheme of the utility model is that: the floating piston for the gas booster pump comprises a piston rod, a piston and a buffer pad, wherein a hemispherical head is arranged at the end part of the piston rod and is in floating connection with a groove arranged at one end part of the piston; a one-way piston seal is arranged between the piston and the supercharging cylinder barrel, the other end of the piston is sequentially connected with a gland and a cushion pad through screws, and a wear-resistant belt is arranged between the gland and the supercharging cylinder barrel.
Furthermore, the diameter of the hemispherical head is larger than that of the groove port.
Furthermore, the hemispherical head is in floating connection with a groove arranged at one end of the piston by a thermal expansion method.
Furthermore, a spacer bush is arranged between the piston and the one-way piston seal.
The utility model discloses make gaseous booster pump in the course of the work, piston and piston rod, piston and cylinder automatic centering have avoided the friction phenomenon, have alleviateed the degree of difficulty of manufacturing, processing and assembly, have also reduced cost of maintenance simultaneously, have improved manufacturing and production efficiency.
