Abstract

The invention discloses a self-lubricating plunger pump. The plunger pump comprises a pump body and a power mechanism connected with the pump body; two symmetrical plunger assemblies are arranged in the pump body; the two plunger assemblies are arranged in two pressure chambers respectively, one ends of the two pressure chambers communicate with the water inlet and outlet valve, and the other endsof the two pressure chambers penetrate into the position of a movable bearing, and the water inlet and outlet valve is connected with a pressure regulating valve; and the plunger assemblies compriseplunger inserted into the pressure chambers, wherein wool felts are arranged on the plungers in a sleeving mode, water seals and oil seals are arranged on the two sides of the wool felts, the outer rings of the water seals abut against and are fastened on the inner walls of the pressure chambers, the oil seals abut against the wool felts and are fastened on the inner walls of the pump body, and the wool felts are filled with machine oil. The self-lubricating plunger pump has the advantages that butter-free and self-lubricating are reliazed, structure is compact, installation is convenient, size is small, weight is light and the like.

Description

technical field [0001] The invention is a self-lubricating plunger pump. Background technique [0002] Ordinary plunger pumps are mostly lubricated with butter in the oil cup structure. The pump body is heavy and the installation space of the water inlet pipe is narrow. Inlet and outlet valves cause sticking, rendering the valve ineffective. [0003] Therefore, there are grease-free plunger pumps on the market. Usually, ordinary grease-free plunger pumps use ceramic plungers and cloth V-shaped water seals, which are kept sealed by the strong pressure of the V-shaped cloth water seals on the plungers. This pump has the disadvantages of heavy load, easy wear and tear and leakage. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a self-lubricating plunger pump, which can realize that butter does not need to be added regularly during the spraying operation, so as not to bring the butter into the liquid and spray it ...
