Description
Technical field
This utility model relates to a kind of high oil field water injection equipment, especially a kind of plunger type water injection pump.
Background technology
The oil field big flow reciprocating note water pump of prior art, power end many employings eccentric wheel structure, general bent axle passes through
Toggle is connected with fluid end, thus drives the plunger of fluid end to do straight reciprocating motion.As shown in Figure 1, Figure 2, Fig. 3 institute
Showing, wherein bent axle 2 is connected with plunger by crankshaft-link rod assembly, and bent axle 2 is placed in pump by crankshaft-link rod assembly with plunger etc.
In body 1, owing to the reciprocating motion of plunger and the rotation of bent axle 2 all can cause pump housing inner chamber 11 temperature to raise, when temperature is high to one
Can cause plunger locking when determining degree, pump quits work.
The cooling body of prior art water injecting pump is to set water inlet and outlet on a sidewall of the pump housing, is returned by copper pipe
The cavity 11 of the road 5 approach pump housing, the inside cavity part for the pump housing is lowered the temperature.But prior art defect is, as 5 plungers, 7 plungers etc. are big
The water injecting pump of type, the installation in copper pipe loop 5 is inconvenient；Secondly because the motion such as bent axle produces stronger vibrations so that copper pipe returns
Easily rupturing with the connection bearing 63 of the pump housing 1 at water inlet, outlet in road 5, once the water in copper pipe loop 5 enters the pump housing 1
Cavity, pump can be directly resulted in and scrap.
So, if any the temperature solved in the control pump housing, it is ensured that pump normally works, and becomes the skill that industry is urgently to be resolved hurrily
Art problem.
Utility model content
This utility model purpose is to provide a kind of simple in construction, and installs convenient, can effectively control again pump body temperature
Water injecting pump.
Goal of the invention of the present utility model is achieved in that
A kind of plunger type water injection pump, connects assembly including the pump housing, bent axle, plunger and bent axle.It is provided with cavity in the described pump housing；
Described bent axle is placed in described cavity, and the actuating unit outside cavity connects；Described plunger moves reciprocatingly in described cavity；
Described bent axle connects assembly and connects described bent axle and described plunger respectively；The described pump housing is provided with cooling body, described cooling body
It is fixed at the bonnet of the described pump housing；Described cooling body is provided with water inlet and outlet.
In such scheme, described cooling body is cooling water tank, and at the bonnet of the described pump housing, a fixed cover plate, described cold
But water tank is fixed on described cover plate, and cooling water tank is provided with water inlet and outlet.
In such scheme, described cooling body is cooling water tank, at the bonnet that described cooling water tank is fixed on, and cooling water tank
It is provided with water inlet and outlet.I.e. cooling water tank is both as the cooling body of cavity described in the pump housing, again as the bonnet of the pump housing.
In such scheme, described cooling body is cooling circuit, on the bonnet medial wall that described cooling circuit is fixed on, cold
But loop is fixed with bonnet by fixture.Owing to cooling circuit is in cavity, the most attractive in appearance；On the other hand, due to cooling
Loop is to be attached on the sidewall of bonnet so that cooling circuit is when vibrations, and cooling circuit is transported merit with bonnet entirety, reduced back
The risk of road fracture.The preparations such as wherein cooling circuit can use copper pipe, stainless steel tube.
This utility model has the advantage that
1, this utility model due to cooling body be cooling water tank time, owing to cooling body is installed on outside the pump housing, more existing
It is convenient that technology is installed, and water can be avoided to enter cavity, decrease the probability that pump is scrapped.
2, when cooling body of the present utility model is cooling water tank, owing to cooling water tank is installed at pump housing bonnet, it is logical
The contact area crossing whole bonnet is lowered the temperature to the pump housing, and cooling water tank is big with contact area in the pump housing, and cooling rate is fast.
3, cooling circuit of the present utility model attaches when being fixed on bonnet medial wall, be given a shock wait act on time, cold
But loop with bonnet associated movement, thus can disperse stress, reduces cooling circuit in water inlet or the connection of outlet
The risk of bearing's fracture.
