According to the device, the mounting frame is designed to be telescopic; drilling height can bechanged at any time; scale marks are arranged on the mounting frame, so that specific drilling height is changed according to the change of the scale marks; and reading is convenient.

The invention relates to an undercurrent external heat exchanger of a circulating fluidized bed, which comprises a feeding vertical pipe, a feeding chamber, a heat exchanging chamber, a coiled pipe heating surface arranged in the heat exchanging chamber, an inlet header, an outlet header, a first partition wall, a second partition wall, an overflow chamber, an ash returning pipe, and an undercurrent hole; wherein a row of undercurrent holes are arranged at the lower part of the first partition wall between the feeding chamber and the heat exchanging chamber so that both of the upper part and the lower part of the heat exchanging chamber are supplemented by high temperature circulating ash, thus improving the flowing and heat exchanging condition of a dead zone in the heat exchanging chamber; and the upper rand lower temperature gradient of the heating exchanging chamber decreases, which is beneficial to the mixing of the circulating ash; the integral heat exchanging performance of theheat exchanging chamber is enhanced; a walling is arranged next to a side wall; the bend part of the coiled pipe heating surface is buried in the waling, not only bears the support and fixes the coiled pipe and heat exchanger, reduces the vibration of the heat exchanger, but also protects the bend of the heat exchanging surface of the coiled pipe not to be corroded by the circulating ash. The technical solution of the invention is easily realized and beneficial to solve the problems of heat transmission, vibration and abrasion of the external heat exchanger.

The invention discloses a transmission protection device of a screw reinjection pump in a same-well injection-production unit. The device is composed of a middle transmission shaft, sealed cavities of bearings, spline shaft transmission pairs, universal coupling type transmission shafts and flow guide covers. The middle transmission shaft is borne by a rolling bearing and a thrust bearing, the spline shaft transmission pairs are arranged in the sealed cavities and connected with the middle transmission shaft, and the universal coupling type transmission shafts are connected with the middle transmission shaft. The transmission protection device can effectively offset upward axial force of the screw reinjection pump, and therefore impact of the upward axial force on a power device of the same-well injection-production unit is avoided, and violent vibration formed by the eccentric motion, relative to the axes of the flow guide covers, of the screw reinjection pump through the axial force is obviously reduced. The transmission protection device enables the unit to stably run for 360 days, and the protection device conforms to index requirements of the application of an oil field.

The invention provides an automatic closing water-saving valve arranged on a faucet. The automatic closing water-saving valve comprises a shell, a bearing, a control rod, a sleeve part and a water inlet seat. When the automatic closing water-saving valve is opened, the control rod can slowly move down due to gravity and a slight water pressure until an upper abut-against part of the control rod seals up a bearing rod hole; then water flowing into a space between the bearing and the sleeve part from a sleeve hole of the sleeve part is gradually accumulated to squeeze the sleeve part upwards and enable the sleeve part to be deformed, so that the sleeve part seals up the water inlet seat to stop the water flow, and thus, an automatic closing effect is achieved. The deformation process of the sleeve part is progressive, and thus, the sleeve part has an effect of buffering to turn off water, so that water hammer sound is avoided. Moreover, the water pressure is not directly acted to the control rod, and thus, a force which needs to be applied when the control rod is operated is small.

The invention discloses a motor. The motor comprises a shell, a stator and a rotor, wherein the stator is arranged in the shell; the rotor is arranged in shell; a base is arranged below the shell; thebase comprises a buffering device and a brake device; the brake device comprises a control component and a slide component; the buffering device comprises a support sleeve and a support convex column; the support sleeve sleeves the support convex column; and the support sleeve can sleeve the support convex column, and play a role in supporting the motor. When the motor works, strong vibration isgenerated, the vibration is transferred to the base in order to drive the whole motor to vibrate, and the support sleeve and the support convex column on the base cooperate with each other to relievethe vibration of the motor and play a role in buffering, so that the working stability of the motor is improved.
