Plunger pump with good heat dissipation effect

Abstract

The invention discloses a plunger pump with a good heat dissipation effect. The plunger pump comprises a pump body base, a plunger pump body, a cooling water tank, a buffer water tank, a water inlet cooling heat dissipation assembly and a water outlet cooling heat dissipation assembly. The cooling water tank is arranged above the plunger pump body, the buffer water tank is arranged on one side ofthe cooling water tank, cooling pipes are arranged on the side wall of the cooling water tank, the water pump is arranged in the buffer water tank, the water outlet end of the water pump penetrates through the buffer water tank and then is provided with the water inlet cooling heat dissipation assembly, and the water outlet cooling heat dissipation assembly is arranged on one side of the water inlet cooling heat dissipation assembly. According to the plunger pump with the good heat dissipation effect, by arranging the cooling water tank, the buffer water tank and the water inlet cooling heat dissipation assembly, firstly cooling water can be conveyed through the cooling pipes to dissipate heat of the surface of the plunger pump body, the multiple sets of cooling pipes are tightly attachedto the surface of the plunger pump body, the heat dissipation efficiency is high, then the cooling pipes are used for conveying the cooling water to dissipate heat the interior of the plunger pump body, and the heat dissipation effect can be effectively improved.

Description

technical field [0001] The invention relates to the field of plunger pumps, in particular to a plunger pump with good heat dissipation effect. Background technique [0002] The plunger pump is a reciprocating motion driven by the eccentric rotation of the crankshaft. Its suction and discharge are all one-way valves. The one-way valve and the water seal form a closed space. When the plunger is pulled outward, the atmospheric pressure in the working chamber decreases, the outlet valve closes, and the pressure in the working chamber is lower than the atmospheric pressure, which means that the inlet valve opens and the liquid enters the working chamber; when the plunger is pushed inward, the pressure in the working chamber is greater than the external atmospheric pressure, which means The inlet valve is closed, the outlet valve is opened, and the liquid is discharged. In this way, the plunger pump completes a complete single working cycle through one revolution of the crankshaft...

AI Technical Summary

Problems solved by technology

[0003] When the plunger pump is working, the crankshaft rotates at high speed in the plunger pump synchronously with the supporting power mechanism, and the plunger reciprocates at high speed through the connecting rod mechanism, which will generate a lot of heat during this period. The existing technology uses aluminum Alloy material is used as the material of the crankcase and many heat sinks are designed on the crankcase to eliminate these effects, but sometimes the plunger pump is prone to heat up to over 100 degrees Celsius, causing damage to the oil seal and oil viewing window, and leakage of lubricating oil, resulting in Piston pumps are sometimes damaged, and the cooling fins on the crankcase have been used for a long time in the plunger pumps, and dirt is easy to accumulate, which is difficult to remove, resulting in limited heat dissipation
