Description
Technical field:
The utility model ultrahigh pressure liquid-ring isothermal compressor relates to the rear bearing field of components that is installed on the ultrahigh pressure liquid-ring isothermal compressor rear pump cover with the rear bearing parts.
Background technique:
Needing specialized designs to have in ultrahigh pressure liquid-ring isothermal compression can be to being installed at centrifugal pan, bearing bonnet, inside cap and the seal ring that roller bearing in the rear bearing body and single-row radial ball bearing carry out axially locating, and need design that link is arranged, pump shaft above-mentioned part connected into rear bearing parts single piece, so that can be bearing in the bearing of ultrahigh pressure liquid-ring isothermal compressor with the rear bearing parts.
Summary of the invention:
The purpose of this utility model provides a kind of ultrahigh pressure liquid-ring isothermal compressor rear bearing parts, add inside cap and centrifugal pan, bearing bonnet respectively in the medial and lateral that are installed in the rear bearing body on the rear pump cover, to reach the purpose that the roller bearing installed and single-row radial ball bearing are carried out axially locating in the rear bearing body.
A kind of ultrahigh pressure liquid-ring isothermal compressor rear bearing parts, it is made up of rear bearing body, bearing bonnet, roller bearing, centrifugal pan, single-row radial ball bearing, inside cap, spacer and seal ring, rear bearing body, bearing bonnet and rear pump cover link into an integrated entity by bearing bonnet connecting bolt, and rear bearing body and inside cap link together by the inside cap connecting bolt; Roller bearing that is equipped with in the rear bearing body and single-row radial ball bearing are sleeved on the pump shaft, are set with centrifugal pan on the pump shaft on roller bearing right side, are set with seal ring on the pump shaft in inside cap left side; Centrifugal pan is installed on the pump shaft by centrifugal pan pump shaft set screw; Between rear bearing body and rear pump cover, be lined with spacer.
The utility model ultrahigh pressure liquid-ring isothermal compressor is installed on the pump shaft with the rear bearing parts, be used for an end of supporting pump shaft, an end that is pump shaft rotates in roller bearing and single-row radial ball bearing, and roller bearing and single-row radial ball bearing are positioned at the rear bearing body.
The rear bearing body is positioned between bearing bonnet and the rear pump cover, bearing bonnet, rear bearing body and rear pump cover link into an integrated entity by bearing bonnet connecting bolt, and between rear bearing body and rear pump cover, be lined with spacer, so that adjust the gap between rear bearing body and the rear pump cover.
On the pump shaft on roller bearing right side centrifugal pan is installed, centrifugal pan is installed on the pump shaft by centrifugal pan pump shaft set screw, and centrifugal pan can prevent that roller bearing from making axial float in the rear bearing body.
The inside cap that is installed in the single-row radial ball bearing left side is sleeved on the pump shaft, enters into the single-row radial ball bearing in the rear bearing body to prevent dust, and single-row radial ball bearing and roller bearing internal diameter equate, be sleeved on the pump shaft side by side.
On the pump shaft in inside cap left side, be set with seal ring.
Have the bearing support oil duct in the rear bearing body, lubricant oil is lubricated roller bearing in the rear bearing body and single-row radial ball bearing by the bearing support oil duct.
The utility model ultrahigh pressure liquid-ring isothermal compressor links into an integrated entity each part by connecting bolt with the rear bearing parts, and after seal ring is installed, can make roller bearing and single-row radial ball bearing operation reposefully under airtight state in the rear bearing body, its advantage is to operate steadily reliably, and mounting connection structure is simple.
