Solve above-mentioned technical problem, the utility model discloses a technical scheme as follows:
the utility model provides a can keep balanced three hair style diaphragm reciprocating pump of lubricating oil, its includes three crankcase, is equipped with the oil drain port respectively in the bottom of three crankcase, and three hair style diaphragm reciprocating pump still includes circulating oil pipe, is equipped with three interface on the circulating oil pipe and is connected with the oil drain port of three crankcase respectively, still is equipped with lubricating oil discharge port on circulating oil pipe, is equipped with the ooff valve in lubricating oil discharge port department.
The three crankcases are communicated with each other through the circulating oil pipe, so that lubricating oil in the three crankcases is balanced with each other.
Furthermore, a port of the circulating oil pipe is used as a lubricating oil discharge port, a switch valve is arranged at the port, a right-angle joint is installed at the other end of the circulating oil pipe, two three-way joints are installed in the middle of the circulating oil pipe, the other port of the right-angle joint and the third port of the two three-way joints are used as three interfaces, and the three interfaces are respectively connected with oil discharge ports of three crank cases through three straight pipes. The circulating oil pipe is simple in structure and convenient to install.
Further, the three straight pipes are all in the vertical direction. The vertical straight pipe enables the lubricating oil to flow more smoothly.
Further, an end cover is arranged at the lubricating oil discharge port. The end cap prevents dust from entering the lubricant outlet port.
Furthermore, the straight pipe is connected with the right-angle joint and the three-way joint through threads, so that the threads are connected more firmly, and the assembly and disassembly are simple.
Furthermore, the circulating oil pipe is made of stainless steel.
Further, the on-off valve is also made of stainless steel.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses a circulating oil pipe connects three crankcase for lubricating oil in the crankcase communicates each other, and lubricating oil pressure is automatic to be balanced between three crankcase, and under the pressure effect, lubricating oil passes through circulating oil pipe circulation that flows, thereby eliminates three hair style diaphragm reciprocating pump because of the unbalanced problem that produces the oil leak of pressure, has also avoided lubricating oil to leak to the base like this, influences the environment.
2. The circulating oil pipe is formed by mutually assembling the three-way joint, the right-angle joint and the straight pipe, so that the circulating oil pipe is simple in structure, convenient to install and low in cost.
3. An end cover is arranged at the lubricating oil discharge port to prevent dust from entering the lubricating oil discharge port.
