A rotating union communicates with a rotor member and is operable with either compressible or incompressible coolant media that enters the union through a media inlet. The union includes a housing having a counterbore and a tubular carrier member axially moveable in the housing. The union includes a primary seal assembly having a rotating seal member mounted to the rotor member and a non-rotating member mounted to the carrier member and a secondary seal member positioned about the carrier member. The range of the balance ratio of the primary seal assembly is disclosed when the primary seal assembly has imposed upon it a closing force, an opening force or no force.

The invention discloses a method for treating coked wastewater through aerobic and synchronous nitrification and denitrification. Firstly, through culture of nitrobacteria, water comes out from an aerobic pool; NH3-N is less than 1 mg / l; secondly, the volume of sludge is improved so as to increase the volume of sludge of the aerobic pool to 50 to 80 percent; and finally the concentration of dissolved oxygen is reduced; and the concentration of the dissolved oxygen of the aerobic pool is reduced from 3 to 6 mg / l to 1 to 3 mg / l. Mass experiment results show that by a method of reducing the concentration of the dissolved oxygen and improving the volume of the sludge of the aerobic pool, the sludge surface has nitrification reaction in an aerobic state; as the inside of the sludge has thickerfloccule, the dissolved oxygen can not penetrate to the inside of the sludge, and the sludge is in an anaerobic state to form denitrification reaction; the removing rate of ammonia nitrogen reaches over 95 percent; the removing rate of total nitrogen reaches 70 percent around; and the method reduces investment, reduces energy consumption and keeps the stable quality of outlet water.

A filter element has a preferably multilayer structure of a pleated filter medium (3) with a plurality of individual filter pleats (5, 7). Due to an alternating sequence of filter pleats (5) with a first pleat height (h1) and filter pleats (7) with a second pleat height (h2), more effective filter surfaces are available than with filter pleats with a uniform pleat height. Upon throughflow by a fluid to be filtered, a lower surface load for the filter medium (30 and lower passage speed of the fluid are present during filtration. A static loading of the filter medium (3) during operation of the filter is then reduced. A hydraulic circuit has such a filter element (1).

Conductor thermal stripping pliers relate to electric heating tools and are special tools for stripping thermoplastic plastic sheaths. It is widely used in thermal stripping of wire insulation in aerospace, military and industrial industries. In the present invention, a heat pipe type heating structure is arranged in the stainless steel tweezers profile product, the front end is a blade for stripping wires, and a U-shaped resistance wire is arranged in the heat pipe at the blade, and the U-shaped structure is used to replace the original I-shaped structure at the blade. Resistance wire, thus doubling the effective power accordingly. In the supporting part, the original single-strand resistance wire is changed into double-strand parallel connection, the surface area of ​​the resistance wire in this part is doubled, the surface load is reduced by half, and the effective resistance and reactive power loss are reduced by half, and the hot and cold joints are moved into the The body meets the technical requirements of the heat pipe. As a result, the reactive power loss of the product is reduced, and the performance is obviously greatly improved.

The invention discloses a full-automatic electric heater for a water tank. The full-automatic electric heater comprises U-shaped electrical heating components, a controller, a protection cover, a radiating protection sleeve, a flanged connecting piece and a first temperature measuring device. The controller is mounted in the protection cover. An opening is formed in one end of the protection cover. One end of the radiating protection sleeve is connected with the opening, and the other end of the radiating protection sleeve is connected with the flanged connecting piece. The port of each U-shaped electrical heating component is connected with the flanged connecting piece. The first temperature measuring device is mounted in parallel with the U-shaped electrical heating components, and is at a certain height. The U-shaped electrical heating components and the first temperature measuring device are electrically connected with the controller. The full-automatic electric heater has the advantages of being convenient to disassemble and assemble, long in service life and compact in space.

The invention relates to the technical field of treatment of textile printing and dyeing wastewater, in particular to a combined process for treating textile printing and dyeing wastewater, comprising the steps such as neutralizing, coagulating and precipitating, filtering with an O / A combined biofilter, activating with an active enzyme promoter, adsorbing with a constructed wetland tank, precipitating, sterilizing, and discharging; the combined process provided by the invention has good wastewater purifying effect and enables continuous treatment of batch production wastewater.

The invention provides a high-safety electric heater, which includes an electric heating assembly and an electric heating tube shield. The electric heating assembly includes a fixing flange and 18 U-shaped tubes. The fixing flange is also provided with a temperature sensor. The electric heating tube shield includes a wiring shield and a protective cover. The present invention can make the U-shaped tube shorter when the diameter is constant, and can choose a smaller container after being shortened. Due to the distribution of the U-shaped tube The number of roots is more, the heat dissipation area is increased, the surface load will be lower, and the service life will be longer; the wiring shield and the cover are formed by the mold at one time, which greatly shortens the working hours of the original metal processing, and the material is made of insulating and high temperature resistant materials. , the insulation performance has been greatly improved. There is also a temperature sensor jack on the inner wall of the wiring shield, so that the wire of the temperature sensor will not come into contact with the high-voltage part of the heater, ensuring safety without affecting Cover installation and removal.

The invention provides a bogie hearth for a bogie hearth type resistance furnace. The bogie hearth for the bogie hearth type resistance furnace is formed by cast iron which is used for bearing workpieces, a fire-proof layer, a first thermal insulation layer, a second thermal insulation layer, a base plate layer, a heating element, a thermal preservation brick and a bogie hearth body which are arranged from top to bottom sequentially; the base plate layer is formed by a plurality of strip-shaped furnace bottom plates in a splicing mode; the furnace bottom plates are made of heat resisting steel; splicing positions of the adjacent furnace bottom plates are in hasp modes; splicing positions of the furnace bottom plates are provided with thermal expanded and cold contracted gaps; the heating element is bent to be in a wave band shape through belts; the heating element is fixed on the thermal preservation brick. The bogie hearth for the bogie hearth type resistance furnace has the advantages of guaranteeing the furnace bottom temperature; improving the surficial area of the heating element, reducing the surface load of the heating element and prolonging the service life of the heating element due to the fact that the heating element is arranged on bogie hearth; meanwhile avoiding short circuit due to the fact that oxidized iron sheets fall on the heating element and improving the production safety due to the furnace bottom plates.
