Abstract
The utility model discloses a flanged high-pressure pump. The flanged high-pressure pump comprises a pump body, an inlet end, an outlet end, a rotor and vanes, wherein the pump body is provided with the inlet end and the outlet end, the rotor is arranged in the pump body, and the vanes are arranged on the rotor; and a bushing is arranged outside the rotor, the rotor is in transmission connection with a motor through a rotor shaft, a front graphite bearing and a rear graphite bearing are mounted on the rotor shaft, a locating pin is arranged at the upper ends of the front and rear graphite bearings, a rear retaining ring and a rear cover plate are mounted at the rear end of the rear graphite bearing, vane thimbles matched with the vanes are arranged at one sides of the vanes, a mechanical sealing member and a sealing member friction disc are further arranged on the rotor shaft, an L-shaped ring, an O-shaped ring and a front clamping spring are arranged on the sealing member friction disc, a deep-groove ball bearing is sleeved at the outlet end of the rotor shaft, a flange is arranged outside the deep-groove ball bearing, and an O-shaped ring is cushioned between the rear cover plate and the rear graphite bearing. The flanged high-pressure pump has the beneficial effects that the structure is more reasonable, the difficulty of design is low, the production cost is low, the noise and vibration are little, and the sealing performance is better.
Description
Technical field
The utility model relates to a kind of water pump, relates in particular to a kind of high-pressure water pump.
Background technique
At present, the common water pump that uses in market can not bear higher pressure, can not be applicable in the hyperbaric environment especially, like this so that Applicable scope dwindle, and work the time very large noise and vibration can occur, so that machine is easy to damage, reduced the operating life of high-pressure service pump, also formed noise pollution etc.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of flanged high-pressure service pump.
To achieve these goals, technical solution adopted in the utility model is:
A kind of flanged high-pressure water pump, comprise the pump housing, the upper inlet of the pump housing and outlet end, rotor and epitrochanterian blade in the pump housing, rotor is provided with a lining outward, rotor is connected with motor-driven by rotor shaft, front graphite bearing and rear graphite bearing are installed on the rotor shaft, front graphite bearing and rear graphite bearing upper end are provided with a locating stud, rear graphite bearing rear end is equipped with rear back-up ring and back shroud, side at blade is provided with the blade thimble that matches with blade, also be provided with mechanical sealing element and Sealing friction disk on the rotor shaft, the Sealing friction disk is provided with L shaped circle, O shape circle and front jump ring, rotor shaft outlet end cover has a deep groove ball bearing, and deep groove ball bearing is provided with flange outward.
Be lined with O shape circle between described back shroud and the rear graphite bearing.
The beneficial effects of the utility model: structure is more reasonable, design difficulty is little, and cost of production is low; Noise and vibration is little, has improved the working life of machine; Sealability is better.
