Abstract
The invention provides a chemical centrifugal pump, and relates to a pump, in particular to the chemical centrifugal pump. The chemical centrifugal pump comprises a bearing box body, wherein a cooling water jacket is fixedly connected with the back end of the bearing box body in a sealed way, and is covered at the outer side of a bearing in a matched way, the lower end of the side wall of the cooling water jacket is provided with a cooling water inlet, and the upper end of the side wall of the cooling water sleeve is provided with a cooling water outlet. Through the arrangement, the chemical centrifugal pump has the advantages that the temperature rise of the bearing can be effectively reduced, so the bearing cannot be easily locked or damaged, and the service life of the pump is prolonged.
Description
Technical field
The present invention relates to a kind of pump, particularly a kind of chemical centrifugal pump.
Background technique
Existing chemical centrifugal pump, during the higher material of its delivery temperature, can cause in bearing housing lubricant oil temperature rise higher, and bearing is prone to locking, damages phenomenon.
Summary of the invention
The object of the invention be to provide a kind of good heat dissipation effect, long service life chemical centrifugal pump.
The present invention includes bearing housing, the cooling jacket of fixing and be tightly connected in the rear end of described bearing housing, described cooling jacket coordinates the outside that covers in bearing, in the lower end of the sidewall of described cooling jacket, cooling water intake is set, and in the upper end of described cooling jacket sidewall, coolant outlet is set.
The present invention passes through in the rear end of bearing housing, and the arranged outside cooling jacket corresponding to bearing, can effectively reduce the temperature rise of bearing like this, makes bearing be difficult for locking, damage, and extend the working life of pump; The centrifugal pump that is arranged so that of cooling jacket can more than 400 material of delivery temperature.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
In figure, 1, bearing housing, 2, cooling jacket, 3, cooling water intake, 4, coolant outlet.
Embodiment
