The slurry pump is characterized in that the outline of the cam forms a correction curve shape of a constant speed spiral line. The slurry pump can relieve processing and installation accuracy, reduce machine volume and weight, and enhance the performance index of operation under the premise of generating large slurry discharge amount with uniform flow quantity.
Description
The utility model relates to a kind of mortar pump, especially the mutual-inverse type mortar pump.
At present, mortar pump with top standard, master-slave mode normally, be that piston cylinder is divided into working piston cylinder and compensating piston cylinder, cam adopts circle wide, the compensation cam adopts the correlation function curve, and discharge pipe only directly links to each other with a valve chamber of a pump head, and transmission line adopts the motor--shaft joint--Placement of clutch--speed reducer--working spindle.These characteristics can satisfy the big and flow advantage of uniform of plasma discharge amount, but, the plasma discharge flow of above-mentioned mortar pump is determined by clutch release slave cylinder, and less than the clutch release slave cylinder flow, adopt the mortar pump of this structure, when flow was big, the physical dimension of piston cylinder was very big, very high to the processing and the installation precision requirement of cam in addition, the kind of drive of mortar pump has increased the weight of the weight and the cost of machine greatly.
The purpose of this utility model provides a kind of can the generation under big plasma discharge amount and the uniform prerequisite of flow, can alleviate processing and installation precision, reduces the machine volume and weight, thereby improves the mortar pump of service behaviour index.
The technical solution of the utility model is: a kind of mortar pump, form by motor, belt wheel, retarder, working spindle, cam, piston cylinder, rocking arm, pump head and piston, pump head is made up of two valve chambers, pulp-absorbing pipe and plasma discharge hole, pump head is connected with piston cylinder by valve chamber, motor drives retarder Control work motion of main shaft by belt wheel, working spindle is characterized in that by cam and the plasma discharge of rocking arm driven plunger described cam profile is the fair curve shape of constant velocity spiral.The work section of described cam is a constant velocity spiral, and changeover portion adopts fair curve.Two valve chamber structures of pump head are identical, and two valve chambers directly link to each other with pulp-absorbing pipe, discharge pipe respectively.Two valve chambers are provided with two valve balls up and down.The Placement of transmission line is that motor links to each other with retarder by belt wheel, and retarder links to each other with working spindle.Piston mechanism is that two pistons of two identical cam mechanism parallel waies are formed, and two pistons are arranged according to certain phase angle.
Working principle of the present utility model is: a kind of mortar pump, form by motor, belt wheel, retarder, working spindle, cam, piston cylinder, rocking arm, pump head and piston, pump head is made up of two valve chambers and plasma discharge hole, pump head is connected with piston cylinder by valve chamber, motor drives retarder Control work motion of main shaft by belt wheel, working spindle is characterized in that by cam and the plasma discharge of rocking arm driven plunger described cam profile is the fair curve shape of constant velocity spiral.The work section of described cam is a constant velocity spiral, and changeover portion adopts fair curve.Therefore, the requirement on machining accuracy to cam reduces.The Placement of transmission line is that motor links to each other with speed reducer by belt wheel, and speed reducer links to each other with main shaft.Like this, just, simplified transmission line, reduced machine weight and cost satisfying under the situation of work requirements.Piston mechanism is that two pistons of two identical cam mechanism parallel waies are formed, and two valve chamber structures of pump head are identical, and two valve chambers directly link to each other with pulp-absorbing pipe, discharge pipe respectively, and two valve chambers are provided with two valve balls up and down.Like this, two-piston can alternation, and the mortar pump flow is formed by stacking by two-piston cylinder flow, is different from the characteristics of the discharge rate of normal sands stock pump by the working pump decision, and under equal operating mode, described mortar pump significantly reduces than the physical dimension of normal sands stock pump.
