The invention discloses a method for rust protection of stator and rotor cores. Epoxy resin paint is sprayed on the surfaces of stator and rotor cores to be subjected to rust-proof treatment, and then solidification treatment is performed. Since the epoxy resin paint and impregnating varnish belong to paint of the same kind, and through experimental verification, a chemical reaction does not occur, cleaning of antirust paint is avoided, thereby greatly lowering the operation difficulty of rust-proof treatment, and improving the operability of a rust-proof treatment method for the stator and rotor cores.

The invention relates to an ultrasonic testing device for an aluminium alloy slab ingot. The ultrasonic testing device comprises an ultrasonic equipment support (6), a portable ultrasonic apparatus (7), a probe line (8), a water switch (11) and a pedestal (16). The ultrasonic testing device is characterized in that the pedestal comprises three support balls. The probes can divided into two types of a water-spraying type straight probe and a contact type straight probe according to functions of the probes. The ultrasonic testing device also comprises a connecting rod (9) and a steering shaft (15). With the ultrasonic testing device, conditions that a detection personnel bends down in a detecting process can be prevented through the effects of the connecting rod (9) and the steering shaft (15); fatigue of the detection personnel can be alleviated; and the ultrasonic testing device is adaptable to detection work of workpieces in different specifications. The invention also provides a method for using the ultrasonic testing device.

The invention provides an esomeprazole sodium or omeprazole sodium content determination method. The method comprises the operation steps that: a sample requiring determination is fetched; precise weighing is carried out; an alcohol-water solution is added, such that the sample is dissolved; with a potentiometric titration method, titration is carried out by using a sulfuric acid titration solution or a hydrochloric acid titration solution, such that the content of esomeprazole sodium or omeprazole sodium is obtained. Each 1mmol of H<+> is equivalent to 36.74mg of C17H18N3NaO3S. An alcohol-water volume ratio is (20-100%):(80-0%). The alcohol is ethanol or methanol. The mass volume ratio of the sample and the alcohol-water solution is 2-10mg / ml. The detection method provided by the invention has large sudden-change value, such that the method is beneficial for titration terminal determination, and the determination of the content of esomeprazole sodium or omeprazole sodium is more accurate. Also, with the method provided by the invention, precipitation is prevented, such that subsequent cleaning work is prevented, and operation is more convenient.

The invention belongs to the field of hardware for daily use, and particularly relates to a clamping fixing type towel rack. Towels can be fixedly clamped by the clamping fixing type towel rack. The clamping fixing type towel rack comprises a group of suckers. The suckers are connected with a wall, connectors are arranged on the suckers, and towel bars are arranged between the symmetrical connectors in a connected manner. The clamping fixing type towel rack is characterized in that connecting sleeves sleeve the towel bars, rotary shafts are arranged on the connecting sleeves, and rotatable compression bars are connected onto the rotary shafts. The clamping fixing type towel rack has the advantages that the towels which are suspended on the towel bars can be compressed, can be prevented from dropping due to external interference and accordingly can be prevented from being stained due to dropping.

The invention discloses a polishing head with a vacuum suction cup. According to the polishing head, a workpiece can be quickly and stably sucked, independent rotation can be realized, the rotation speed can be adjusted by a polishing machine, and the polishing pressure can be changed. The polishing head consists of the suction cup, a high-speed rotary joint, a vacuum hose and a vacuum generator which are connected in series in sequence. The suction cup is formed by two schemes: 1, the suction cup comprises a disk face, a disk bottom, a vacuum tube, bolts for connecting the disc face with the disc bottom, and pressing blocks of different masses, wherein the pressing blocks of different masses are combined to adjust the polishing pressure on the workpiece; 2, the suction cup comprises a disc face, a disc bottom, a positioning shaft, a vacuum tube, a positioning cylinder, a spring, a pressure regulating nut, a retainer, a limiting rack and a retainer end face ring, wherein the polishing pressure acting on the workpiece is changed by compressing the spring through the pressure regulating nut. The polishing head can be a substitute for the conventional methods for adhering the workpiece through substances such as glue and soluble wax, and is low in cost and easy to operate, and the machining efficiency and the machining precision can be improved. The polishing head can be combined with a rotary swing gravity type grinding and polishing machine for use.

The invention discloses a spraying structure of a sink dishwasher. The spraying structure comprises a dynamic spraying arm and at least one static spraying arm, wherein the dynamic spraying arm is arranged at the bottom of a sink body of the sink dishwasher for rotatable spraying; the at least one static spraying arm is arranged on the side wall of the sink body of the sink dishwasher for static directional spraying; at least one group of first spraying units is arranged on the dynamic spraying arm; at least one group of second spraying units is arranged on the static spraying arm; a pressurizing opening and a steam generating opening are formed in the static spraying arm. The invention provides the spraying structure which has the benefits that in combination with dynamic and static spraying, washing dead corners are covered, the washing effect is improved, and the problem of cleaning of tableware on a second shelf is solved; as the pressurizing opening is formed, the coverage area ofa spraying opening is enlarged, so that the spraying increased, and the washing time is shortened; water is turned into a form of water mist, so that scouring and soaking functions are realized; as the steam generating opening is formed, steam is sprayed from multiple steam outlets in the lower part, so that soaking and disinfecting functions are realized.
