Abstract
Provided is an air case for a mud pump. The air case not only satisfies the high elasticity requirement, but also guarantees that when the air case is use, balanced bag operation is maintained. The air case comprises a bag, which is made of rubber materials and has an inwardly-recessed bottom surface. A balance plate is arranged in the bag, and is fixedly connected on the inner bottom surface of the bag. The balance plate added in the bag achieves the balance effect and has the function like a 'piston' as well. When high-speed high-frequency pressure fluctuation occurs, due to the arrangement of the balance plate, the bag is divided into two working chambers, so as to stabilize the air case deforming rate, to avoid too large an impact force applied to the bottom of the air case, to guarantee the working efficiency all the time and to achieve the effect of balancing the integral bag. The air case, which is sensitive in deformation, rapid in deformation response and slow in deformation speed, avoids common damage of the case (bag) bottom and therefore has a greatly prolonged service lifetime.
Description
Technical field
The utility model relates to the improvement to the slurry pump air tank.
Background technique
For pressure and the flow oscillation that reduces drilling mud pump, air tank is installed on discharge pipe usually, can make slurry pump reach best suction effect, be widely used in oil, in the pressure duct that chemical industry is carried, it can balance slurry pump high pressure fluid peak value, play steady pressure, the effect of reducing the loss.
For keep-uping pressure and discharge capacity stable, its underpart capsule (basis) is known from experience to-and-fro motion to air tank, with the volume of change external cavity at work.At the volley, because it is big to be communicated with the mud pressure fluctuation of cavity, the situation that the bottom utricule is patted the cavity bottom surface often appears, and often occur rapidly, the beating state of high frequency.This can cause the utricule middle part fatigue fracture to occur on the one hand, can occur the utricule bottom on the other hand and cause breakage because of intensity.
For pursuing the working life of air tank utricule, need its material is carried out high elasticity and the adaptive improvement of high-temperature, this can cause the reduction of utricule bulk strength, occurs the situation of utricule work unbalance loading distortion at work.
The model utility content
The utility model provides a kind of requirement that can adapt to high elasticity at above problem, can guarantee in the time spent slurry pump air tank of utricule maintenance work balance again.
The technical solution of the utility model is: comprise the utricule of rubber material inner bottom surface indent, utricule inside is provided with balance plate, and described balance plate is fixedly connected on the inner bottom surface of described utricule.
The inner bottom surface central position of described utricule is embedded with nut, and described balance plate is connected on the inner bottom surface of described utricule by the screw that is connected with described nut.
The diameter of described balance plate is slightly less than the utricule internal diameter, makes the slit between balance plate and the utricule inwall form the damping air vent.
Described balance plate body is that hard material is made, and the balance plate edge is provided with the soft shirt rim of a circle, and described soft shirt rim contacts the inwall of described utricule; Described balance plate is provided with at least one spilehole that plays damping function.
The utility model is set up a balance plate in utricule, its effect is when work, has both played balanced action, plays similar " piston " again.Occurring rapidly, when high-frequency pressure fluctuates,, will form two active chambers in the utricule owing to its existence, the rate of deformation of energy stable air bag, bigger impact force is born in unlikely air tank bottom, and the efficient can guarantee at every turn to work the time, and utricule integral body is played balanced action.Air tank of the present utility model distortion sensitivity is good, be out of shape corresponding soon, but strain rate is mild, has avoided the situation of bag (capsule) body bottom frequent " hitting mashed ", has prolonged the working life of air tank greatly.

Embodiment
The utility model is as shown in Figure 1: comprise the utricule 1 of rubber material inner bottom surface indent, utricule 1 inside is provided with balance plate 4, and described balance plate 4 is fixedly connected on the inner bottom surface of described utricule 1.
The inner bottom surface central position of described utricule 1 is embedded with nut 5, and described balance plate 4 is fixedly connected on the inner bottom surface of described utricule 1 by the screw 2 that is connected with described nut 5.For guaranteeing to connect effect, can set up pressing plate (playing the pad effect).
The diameter of described balance plate 4 is slightly less than utricule 1 internal diameter, makes the slit between balance plate 4 and utricule 1 inwall form the damping air vent.
Another mode of execution of the present utility model is as shown in Figure 2: described balance plate 4 bodies are that hard material is made, and balance plate 4 edges are provided with the soft shirt rim 6 of a circle, the inwall of the described utricule 1 of described soft shirt rim 6 contacts; Described balance plate 4 is provided with at least one spilehole that plays damping function 7.Being equivalent to like this provides a buffer area to distortion.
