In conjunction with shown in Fig. 2, Fig. 5 and Fig. 6, stuffing-box 1 connects crankcase 30, sets that there are three be used in the crankcase 30
With crosshead cooperation guiding cavity 31, described three be oriented to cavitys 31 between with air guide runner 32 be interconnected.
Three of the prior art are oriented to cavity 31 and are independent from each other, when crosshead travels forward, crosshead and oil sealing
Between can form certain pressure, the presence of pressure makes oil sealing have the risk of abjection.When crosshead moves backward, crosshead and oil
Region between envelope can form certain vacuum, and the presence of vacuum can be such that oil seal lip slightly opens, and suck air, the sky of sucking
Gas can quickly mix with lubricating oil in crankcase that lubricating oil is made to generate a large amount of bubbles, influence the lubricating quality of lubricating oil.
After three guiding cavitys 31 are got through with air guide runner 32, since three crossheads are in motion process, at one ten
Prefix is while travelling forward, and also there are one crosshead is moved backward, in this way since crosshead moves back and forth
The positive pressure and negative pressure of generation can mutually be circulated by air guide runner, are in normal pressure to make positive pressure and negative-pressure balancing, greatly reduced
The probability described above happened.
Preferred embodiment is connected between each two adjacent guiding cavity 31 with two air guide runners 32 being mutually parallel, is made
Pressure Fast-Balance.
More there are the scheme of choosing, each two adjacent two air guide runners 32 being oriented between cavity 31 to be respectively communicated with two phases
The top and bottom of adjacent guiding cavity 31.Air guide runner 32 in the present embodiment also has the function of another, due to air guide
After guiding cavity 31 is interconnected by runner 32, three lubricating oil being oriented in cavitys 31 can mutually circulate, and be exchanged with each other, from
And make crosshead sufficient lubrication.It is from top to bottom lubricated oil positioned at 31 bottom of cavity and top air guide runner 32 is oriented to
It exchanges comprehensively, so that lubricating oil is exchanged abundant.
Connection three is oriented to the air guide runner 32 at 31 top of cavity in coaxial arrangement, is connected to three and is oriented to 31 bottom of cavity
Air guide runner 32 is in coaxial arrangement.
It when making air guide runner 32, can drill in crankcase side wall, make three to be oriented to cavity 31 and be connected to, using
When, the hole month of crankcase side wall is blocked with plug.
The operation principle of the utility model is：
Clear water valve seat 8 connects clear water pipeline, and when plunger 100 draws water along the axial retrogressing of stuffing-box 1, clear water steel ball 11 is in column
It fills in suction lower compression clear water spring 10 to decline, and enters in clear water spring base channel 13,12 channel of clear water valve base channel
It is opened, clear water with pressure is successively by clear water valve base channel 12, clear water spring base channel 13, into after water ring 7 and clear water runner 6
It enters in the gap between 4 inner wall of plunger 100 and baffle ring, the surface of plunger 100 is rinsed during entrance, rinse
Impurity afterwards is stored in precipitation tank 14.
When plunger 100 pushes forward water outlet, positive pressure is formed to the water in stuffing-box, on the one hand the water of positive pressure pushes clear water
Steel ball 11 blocks clear water valve base channel 12 upwards, on the other hand rinses the impurity in precipitation tank 14, impurity is led from precipitation tank
Go out, is exported from the water outlet of pump together with water.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although stuffing-box 1, main water seal 2, secondary water seal 3, baffle ring 4, clear water check valve 5, clear water stream is used more herein
Road 6, into water ring 7, clear water valve seat 8, clear water spring base 9, clear water spring 10, clear water steel ball 11, clear water valve base channel 12, clear water bullet
Spring abutment channel 13, main water seal washer 15, secondary water seal positioning sleeve 16, secondary water seal positioning seat 17, spring base 18, compresses precipitation tank 14
