Embodiment:
As shown in Figure 1-Figure 3: by pump, be arranged on the constant temperature pump that heating equipment in the pump case and motor are formed, be made up of pump case (1), impeller (2), stator (3), electric heating tube (6), pressure control switch (8), temperature control element (9), plastic junction box (7), pump cover (10), motor (20) etc., heating equipment is made up of electric heating tube (6), the plastic junction box (7) that metal abaculus (20) are set, pressure control switch (8) and at least one temperature control element (9) etc.
As shown in Figure 3, the water inlet flow channel (15) and the stator (3) that are arranged in the pump case (1) are divided into two cavitys that are interconnected (15) and pressure chamber (16) to pump case (1), impeller (2) is installed near in the cavity (15) of motor, and electric heating tube (6) is arranged in the pressure chamber (16) that directly is communicated with water outlet (13).
As shown in Figure 3, it is parallel with electrical axis that the water intake (12) of pump case (1) is arranged on the front of pump case (1), and the end face that the water outlet (13) of pump case (1) is arranged on pump case (1) is vertical with electrical axis.
As Fig. 2 and shown in Figure 4, heating equipment is made up of electric heating tube (6), the plastic junction box (7) that metal abaculus (20) are set, pressure control switch (8) and at least one temperature control element (9) etc.Pressure control switch (8) and temperature control element (9) are fixedly mounted in the plastic junction box (7) that metal abaculus (20) are set, the surface of the metal abaculus (20) in temperature control element (9) and the plastic junction box (7) contacts, liquid in the surface of metal abaculus (20) and the pump case directly contacts, because the speed of metal conduction heat energy is fast, temperature control element (9) can detect the true temperature of the liquid in the pump case (1) effectively.The base (71) of pressure control switch (8) is the some of plastic junction box (7), the one side of the film (81) of decomposition pressure control switch (8) communicates with pump case pressure chamber (17), when the fluid pressure in the pump case (1) increases to setting pressure, film (81) action is connected pressure control switch (8).
As shown in Figure 2, the bottom surface that plastic junction box (7) is connected with pump case (1) has breach (73), and the liquid that spills because of the seal ring ageing failure can be discharged outside the plastic junction box (7).
