2, since Stuffing box in be added with spacer ring, so the front have only 3 the circle packing seals, very easily cause the sealing bad, can form medium and be leaked to the spacer ring place, and then cause medium to flow in the cooling medium, pollute simultaneously.
3, because neutral position adopts in the Stuffing box is spacer ring, its cooling medium heat-absorbent surface is too small, in the time of can causing the pump head medium temperature too high, is difficult for cooling, forms the cooling illusion.
4, the inlet and outlet connectors of cooling medium causes and takes over and very inconvenience of maintenance in the carriage the inside, and the maintenance difficulty is high.
In view of the deficiency of above-mentioned filler cooling structure, therefore a kind of heat radiation good cooling results is proposed, there is not the medium pollution of leakage, overhaul Stuffing box cooling structure easily.
The model utility content
To the above-mentioned deficiency that existing technology exists, the purpose of the utility model just is to provide a kind of heat radiation good cooling results, places the leakage medium and pollutes, and overhauls combined stuffing case cooling structure easily.
To achieve these goals, the technological scheme of the utility model employing is such: a kind of combined stuffing case cooling structure comprises pump head, plunger, Stuffing box and support carriage; Said Stuffing box is sleeved on the plunger; Between pump head and support carriage, be provided with the transition body, this transition body is set on the Stuffing box, in the transition body, is provided with the cooling channel; The import of this cooling channel is positioned at an end of transition body, and outlet is positioned at the other end of transition body.
Further, also be processed with one around the Stuffing box circular groove in one week at the Stuffing box outer wall, said transition body is positioned at ring slot outside, and with the circular groove sealing, makes and form sealing cooling chamber between circular groove and the transition body; This cooling chamber is communicated with the interior cooling channel of transition body.
Further, also be provided with the O-ring seals groove, the O-ring seals that matches is housed in the O-ring seals groove in the circular groove both sides.
Compared with prior art, the advantage of the utility model is: simple in structure, practical, the heat radiation good cooling results is avoided polluting because of revealing medium, and maintenance is convenient.

Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
Embodiment: referring to Fig. 1 and Fig. 2, a kind of combined stuffing case cooling structure comprises pump head 1, plunger 2, Stuffing box 3 and support carriage 4; Said Stuffing box is sleeved on the plunger; Between pump head and support carriage, be provided with transition body 5, this transition body is set on the Stuffing box, in the transition body, is provided with the cooling channel; As preferably, said cooling channel is the single cycle cooling channel; The import 6 of this cooling channel is positioned at an end of transition body, and outlet 7 is positioned at the other end of transition body.Utilize the transition body that high temperature pump head and support carriage are separated respectively, in the practical operation, between them through pin 10 location, thereby be implemented in the effect of cooling Stuffing box when the transition body cooled off.
Also be processed with one around the Stuffing box circular groove 8 in one week at Stuffing box 3 outer walls, said transition body is positioned at ring slot outside, and with the circular groove sealing, makes and form sealing cooling chamber between circular groove and the transition body; This cooling chamber is communicated with the interior cooling channel of transition body.Thereby reach the cooling filler and prevent the phenomenon of the high thermal energy conduction of pump head to support.
Also be provided with O-ring seals groove 9 in circular groove 8 both sides, the O-ring seals that matches is housed in the O-ring seals groove.
In the actual production process; In order to simplify transition body and pump housing cooling recirculation system; Cut down finished cost, the bolt hole that is connected usefulness with support carriage, pump head is arranged on the transition body, and the tapped hole that directly links to each other of filler casing and transition body; Can not only effectively solve the connectivity problem between them like this; But also effectively avoided the support carriage directly to link to each other with the pump housing and simultaneously prepared filler casing connecting through hole and the complex stress condition that causes on the transition body with transition body, transition body, and also that the transition body is the complicated tensile stress state that receives changes comparatively single compression chord state into, and this can effectively improve the working life of part in hot environment.And transition body and pump head, support carriage can guarantee the concentricity of Stuffing box in the transition body through finger setting.Cooling in it communicates with Stuffing box cooling chamber, so more helps the cooling of Stuffing box and transition body.
