Abstract
The utility model relates to a low-noise air pump used in hospitals. The low-noise air pump is characterized in that a single-phase electric motor is adopted, a flywheel is mounted before an eccentric shaft, double connecting rods are connected onto the eccentric shaft through two bearings, double die pieces form two air cylinders symmetrically arranged at 180 degrees, the bearings on the eccentric shaft are symmetrically arranged on the two sides of the axial line of the electric motor, a rubber cushioning pad is arranged on a base of the air pump, and a sound deadening shield is arranged outside the pump in a matched manner. The utility model has the benefits as follows: about two thirds of electric energy can be saved under identical output air pressure and flow; the air pump operates steadily, has small shock and low noise; the noise of the air pump operating normally can reach below 57.5 decibels; the air pump conforms to departmental standard requirements of medical instruments and can be placed in a sickroom without additionally building a pump house; and the installation and use are convenient.
Description
Technical field
The low noise air pump that uses in the hospital that the utility model medical system is used.
Background technique
Not having the clean pressurized air of oil for obtaining, adopt piston type the oil gas pump to be arranged through the filter oil filtering system usually, is a kind of revolving blade air pump, but the mortgage air temperature rise of this pump output is higher and contain mist of oil, and the low pressure temperature of output is lower.Yet it is a kind of single connecting rod but the pump of diaphragm, single cylinder, and reaching the output rated pressure is 0.5 kilogram every square centimeter, and rated flow is that need to adopt power be that 2.2 kilowatts motor drives to the pressurized air of 0.5 cubic metre of per minute.General individual event motor power (output) is below 0.75 kilowatt, can only adopt three phase motor to match with compressor pump for this reason.This installation to the user brings many inconvenience.And because the power consumption of power is many, the colleague, must dispose equilibrium block and overcome the centrifugal force that eccentric shaft produces for center of gravity and the electrical axis that makes eccentric shaft overlaps owing to have only single connecting rod on the eccentric shaft on motor main shaft.But it is steady inadequately that pump still turns round when work, and vibrations are big, noise is big, installs so pump does need to connect pump house in addition when medical equipment use, and the user uses inconvenience, the cost of investment height.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the low noise air pump that uses in a kind of hospital is provided, it is 0.5 kilogram every square centimeter in the output rated pressure, and 0.5 cubic metre of 0.75 kilowatt of wasted work rate only then can adopt the individual event motor during flow per minute.This low pressure does not have the oil gas pump can save energy consumption.The utility model is to carry out like this, single phase motor connects the 220V power supply, drives the eccentric shaft rotation after startup, drives two connecting rods by two bearings that are installed on the eccentric shaft, pressing plate is fastened on small end, and the canvas filler rubber diaphragm is fastened between two block pressur plates and moves reciprocatingly with connecting rod.Make symmetrically arranged two cylinders of 180 degree finish an air inlet and exhaust when eccentric shaft whenever circles, each cylinder intake and exhaust each by the control of diaphragm type suction valve and outlet valve, pressurized gas by about two end caps be pooled to pump housing top and export by the gas transmission joint.A flywheel has been installed before eccentric shaft, has been increased the inertia of eccentric shaft running, reduced energy consumption, reduced vibrations.
Bimodulus sheet pump provided by the utility model connects two positions of bearings of two connecting rods and eccentric shaft.Can be the symmetrical both sides at the motor main shaft line, such two cylinders be exhausts simultaneously, can make the pump running steadily, and vibrations reduce.The position of two bearings also can be the homonymy at the motor main shaft line, and the air intake-exhaust of such two cylinders is to intersect to carry out.For the air pump noise in operating is reduced, can on the air pump base, rubber anti-vibration mounting be set, air pump is loaded onto supporting silencer cover outward, and ventilating fan is arranged on the cover, helps the air pump heat radiation.
The beneficial effects of the utility model are, the utility model can save about 2/3 under same output pressure and flow, and this air pump running steadily, shake little, noise is low, the noise of air pump when running well can reach below 57.5 decibels, meets the ministry standard requirement of medical apparatus, can enter the ward, need not to build in addition pump house, easy to install.

Fig. 2 illustrates to sectional structure for the utility model A-A.
Embodiment
With reference to description of drawings the utility model is done following concrete detailed description; As shown in drawings, individual event motor 13 connects the 220V ac power supply, start and drive eccentric shaft 3 rotations, by bearing 5 drive link 6 of installing, the position of two bearings is in the symmetrical both sides of motor main shaft center line, two cylinder 16 air intake-exhausts are carried out simultaneously, between two block pressur plates that canvas filler rubber diaphragm 7 is fastened on and connecting rod joins, reciprocating with connecting rod, cylinder intake has 8 controls of diaphragm type air valve, exhaust is by 9 controls of diaphragm type air valve, volume of cylinder increases when diaphragm 7 moves right, and pressure reduces, and washes suction valve 8 inflow cylinders open from the air that suction port 15 enters, when diaphragm 7 during to left movement volume of cylinder reduce, pressure increases.Pressurized gas just close suction valve 8 and push open outlet valve 9 by about two end caps 10 and 1 be pooled to the pump housing 4 tops, by 12 outputs of gas transmission joint, in order to reduce power, increase the inertia motion of eccentric shaft, a plate-like flywheel 2 has been installed, again in order to make air pump when work reduce vibrations and noise before eccentric shaft.The air pump base has rubber anti-vibration mounting 14, and air pump has supporting silencer cover 11 outward, and air pump of the present utility model can adopt the part manufacturing process manufacturing in addition of common machinery by the accompanying drawing structure.
Claims (1)
1. the low noise air pump that uses in the hospital, comprise the pump housing, end cap, eccentric shaft, connecting rod, canvas filler rubber diaphragm, suction valve, outlet valve, suction port, gas transmission joint, it is characterized in that adopting the individual event motor, a flywheel is installed before the eccentric shaft, connect double link, symmetrically arranged two cylinders of bimodulus sheet composition 180 degree by two bearings on the eccentric shaft, two bearings on the eccentric shaft are in the both sides of motor axis symmetry, the base of air pump is provided with rubber anti-vibration mounting, and pump has supporting silencer cover outward.
