Abstract
The invention discloses a reciprocating plunger pump which comprises a power end machine body, a hydraulic end pump body and a seal box body. The reciprocating plunger pump is characterized in that an insulation board with a through hole is arranged on the hydraulic end pump body and located between the power end machine body and the hydraulic end pump body, the seal box body penetrates through the through hole, a cooling cavity is formed in the insulation board, connected with a cooling water circulator through a pipeline and provided with a cooling cavity water inlet and a cooling cavity water outlet, the cooling cavity water inlet is communicated with a water outlet of the cooling water circulator, and the cooling cavity water outlet is communicated with a water inlet of the cooling water circulator. The reciprocating plunger pump has the advantages that when the reciprocating plunger pump works, heat exchange between the hydraulic end pump body and the power end machine body is blocked by the insulation board, heat is conducted to the cooling water circulator through cooling water in the insulation board for cooling treatment, the cooled cooling water enters the insulation board again for circulation cooling, and heat conducted to the power end machine body is greatly reduced.
Description
Technical field
The present invention relates to a kind of reciprocating pump, especially a kind of reciprocating plunger pump.
Background technique
At the reciprocating plunger pump for boiler feed water, because the temperature of fed sheet of a media is higher, can reach 120 ℃ ~ 150 ℃, high like this temperature will be directly passed to the power end fuselage of reciprocating plunger pump by parts such as the fluid end pump housings, will directly make the lubricating oil temperature in power end fuselage raise rapidly, lubricating oil viscosity reduces, and causes relevant movement parts to burn to death, damage; At present, the air quantity generally producing by the fan blade rotation in fan blade belt pulley reduces the temperature of power end fuselage, but cooling-down effect is limited, cannot reach actual cooling requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide the reciprocating plunger pump that a kind of cooling-down effect is good.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of reciprocating plunger pump, comprise power end fuselage, the fluid end pump housing and sealed letter body, the described fluid end pump housing is provided with the thermal baffle with through hole, described thermal baffle is between described power end fuselage and the described fluid end pump housing, described sealed letter body is through described through hole, the inside of described thermal baffle is provided with cooling chamber, described cooling chamber is connected with cooling water circulation machine by pipeline, described cooling chamber is provided with cooling chamber water intake and cooling chamber water outlet, described cooling chamber water intake is communicated with the water outlet of described cooling water circulation machine, described cooling chamber water outlet is communicated with the water intake of described cooling water circulation machine.
Described cooling chamber water intake and described cooling chamber water outlet are positioned at the same side of described thermal baffle.The cooling water that makes to enter in cooling chamber is fully taken away heat.
Between described cooling chamber water intake and described cooling chamber water outlet, be provided with manger board, cooling chamber described in described manger board is positioned at and described cooling chamber water intake and the described close side of cooling chamber water outlet, described manger board flows out from described cooling chamber water outlet through the longest flow process after the current of described cooling chamber inside are entered by described cooling chamber water intake.The setting of manger board can guide the cooling water entering in cooling chamber to circulate by certain direction, takes away fast and fully heat, has increased the intensity of thermal baffle simultaneously.
In described power end fuselage, be provided with U-shaped cooling tube, described U-shaped cooling tube comprises at least one section of U-shaped body, between cooling water circulation machine described in described U-shaped body is arranged on and described cooling chamber, one end of described U-shaped body is communicated with the water outlet of described cooling water circulation machine by water pipe, and the other end of described U-shaped body is communicated with described cooling chamber water intake.To the heat entering in power end fuselage, carry out cooling.
Described U-shaped cooling tube comprises two sections of end to end U-shaped bodys.Increase the length of the U-shaped cooling tube in power end fuselage, improved cooling effect.
Compared with prior art, the invention has the advantages that thermal baffle is between power end fuselage and the fluid end pump housing, cooling water circulation machine is inputted cooling water in the cooling chamber water intake of thermal baffle, again from cooling chamber water outlet by water drain in cooling water circulation machine, carry out cooling, the cooling water of again processing through cooling to the input of cooling chamber water intake, water resource utilization efficiency is high, when reciprocating type plunger pump work, heat exchange between the fluid end pump housing and power end fuselage is subject to stopping of thermal baffle, and heat absorbs by the cooling water of thermal baffle inside, absorb cooling water after heat and be delivered to the cooling water circulation machine processing of lowering the temperature, cooling water after cooling is processed is again inputted cooling chamber water intake and is absorbed heat, so circulation, the heat of power end fuselage greatly reduces, effectively protected the normal lubricating oil temperature in power end fuselage.
