For solving the problems of the technologies described above, the utility model provides a kind of casing of hydraulic pump of insulation, it is characterized in that: this casing of hydraulic pump, by pump case, is incubated sleeve, electric heating coil, seal ring a, seal ring b, seal ring c and Conduits composition, wherein:
The left side of pump case is provided with the sleeve of ear, and the inner chamber I of sleeve is communicated with the inner chamber II of pump case.
Insulation sleeve is provided with through hole I, through hole II, through hole III; Form the cavity of similar sleeve-shaped between insulation sleeve and sleeve, cavity can be in communication with the outside by through hole II or through hole III.
At the left end of insulation sleeve, insulation sleeve is connected by Spielpassung with sleeve, and is sealed by seal ring a; At the right-hand member of insulation sleeve, insulation sleeve and pump case are fixed by screw and are connected, and at the junction plane place of the two, are sealed by seal ring c.
Electric heating wire snare is rolled on the excircle of insulation sleeve, and is connected with ABAP Adapter through Conduits; Conduits through through hole I, and is sealed by seal ring b.
The Spielpassung type of described insulation sleeve and sleeve is H7/h6, is conducive to being incubated the location of sleeve on sleeve, facilitates installation and removal simultaneously.
At the junction plane place of described insulation sleeve and pump case, insulation sleeve is Ra0.8 with the surface roughness of pump case, and this is conducive to the close contact of the junction plane being incubated sleeve and pump case, and then better realizes sealing under the effect of seal ring c.
Described insulation sleeve is provided with stiffening rib, at minimizing lagging barrel thickness, and then when reducing this casing of hydraulic pump weight, can greatly improves the intensity of casing of hydraulic pump like this.
The beneficial effects of the utility model are: first this casing of hydraulic pump and other component of oil hydraulic pump are assembled into oil hydraulic pump, then electric heating coil is connected with extraneous power supply, now electric heating coil will produce heat, so just ensure that the liquid be positioned in oil hydraulic pump inner chamber can not be frozen in, and then ensure the normal use of oil hydraulic pump; Simultaneously by regulating the change of extraneous source current, the temperature just in adjustable oil hydraulic pump inner chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the casing of hydraulic pump of a kind of insulation of the utility model.
Fig. 2 is the structural representation of the utility model insulation sleeve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.For sake of convenience, " left side " hereinafter, a left side for " right side " and accompanying drawing itself, right direction is consistent, but does not play restriction effect to structure of the present utility model.
Fig. 1 shows the casing of hydraulic pump of a kind of insulation disclosed in the utility model, and composition graphs 2 is known, and this casing of hydraulic pump is by pump case 1, and be incubated sleeve 2, electric heating coil 3, seal ring a4, seal ring b5, seal ring c7 and Conduits 6 form, wherein:
The left side of pump case 1 is provided with the sleeve 1.1 of ear, and the inner chamber I1.2 of sleeve 1.1 is communicated with the inner chamber II1.3 of pump case 1; Insulation sleeve 2 is provided with through hole I2.1, through hole II2.2, through hole III2.3; Form the cavity 9 of similar sleeve-shaped between insulation sleeve 2 and sleeve 1.1, cavity 9 can be in communication with the outside by through hole II2.2 or through hole III2.3.At the left end of insulation sleeve 2, insulation sleeve 2 is connected by Spielpassung with sleeve 1.1, and is sealed by seal ring a4; At the right-hand member of insulation sleeve 2, insulation sleeve 2 and pump case 1 are fixed by screw and are connected, and at the junction plane place of the two, are sealed by seal ring c7.Electric heating coil 3 cover is rolled on the excircle of insulation sleeve 2, and is connected with ABAP Adapter through Conduits 6; Conduits 6 through through hole I2.1, and is sealed by seal ring b5.
In the utility model, described insulation sleeve 2 is H7/h6 with the Spielpassung type of sleeve 1.1.This be conducive to being incubated sleeve 2 on sleeve 1.1 location, the installation and removal of convenient insulation sleeve 2 simultaneously.At the junction plane place of described insulation sleeve 2 with pump case 1, insulation sleeve 2 is Ra0.8 with the surface roughness of pump case 1, and this is conducive to the close contact of the junction plane being incubated sleeve 2 and pump case 1, and then under the effect of seal ring c7, better realize sealing.Described insulation sleeve 2 is provided with stiffening rib 8, at minimizing insulation sleeve 2 thickness, and then when reducing this casing of hydraulic pump weight, can greatly improves the intensity of casing of hydraulic pump like this.
