The invention discloses a plunger type motor pump, and belongs to a plunger pump. The problems of weak strength and low overall power density of a cylinder of the conventional plunger motor pump are solved. According to the plunger type motor pump, a motor stator is assembled in a housing. The two ends of the cylinder are supported in the centers of a left end cover and a right end cover respectively. A motor rotor is sleeved on and fixedly connected with a lug boss on the middle part of the cylinder. N plunger cavities are reserved in each of the left and right end faces of the lug boss of the cylinder. A plunger piston shoe component is arranged in each plunger cavity. Suction and forcing valve components are arranged in correspondence to each plunger piston shoe component on the lug boss of the cylinder. A left swash plate is fixed on the inner side of the left end cover, and a right swash plate is fixed on the inner side of the right end cover. The plate surfaces of the left and right swash plates are parallel. Every two coaxial plunger piston shoe components are pressed against each other through a support rod, and piston shoe heads at the two ends are pressed on the plate surfaces of the left and right swash plates respectively. Reverse thrust generated between the plunger piston shoe components at the two ends and the swash plates and hydraulic acting force in the cylinder are transmitted through the support rods, and internal reacting force is fully utilized, so that the number of the parts is decreased, the overall strength of the pump is strengthened, and the internal space utilization rate of the cylinder is increased.

The invention discloses sand painting performance equipment. The sand painting performance equipment comprises a sand table, wherein an acquisition layer is arranged on the painting surface of the sand table, and a matrix circuit is arranged in the acquisition layer and comprises a signal output end, a signal receiving end and a detection point; horizontal wires of the matrix circuit are connectedwith the signal output end correspondingly, vertical wires of the matrix circuit are connected with the signal receiving end correspondingly, or each horizontal wire of the matrix circuit is connected with the signal receiving end correspondingly, and each vertical wire of the matrix circuit is connected with the signal output end correspondingly; and detection points are arranged at the intersections of the horizontal wires and the vertical wires of the matrix line, each detection point comprises two sets of detection heads, and the two sets of detection heads are connected with the horizontal wires or the vertical wires of the matrix line correspondingly. According to the sand painting performance equipment, a projected image in the sand painting performance does not show hands of a producer, so that the aesthetic feeling of work is improved; and the size of the sand table can be made larger, so that a larger exertion space is provided for the producer.
