Pump vacuum furnace temperature is too high

Pump vacuum furnace temperature is too high

Will inevitably be vacuum furnace in the process of using all kinds of fault, pump vacuum furnace temperature is too high? Under the vacuum furnace manufacturers sent gold to share it with a solution.
(1) check the thermostat setting of the temperature control pump is in accordance with the regulations. If not, should be reset.
(2) pump cooling water flow rate of solid scale or other dirt jam for smaller. Lead to rising pump Yun. Because oil pump must have certain viscosity to ensure the sealing of pump. The viscosity is too small, the sealing performance variation. And pump oil viscosity with temperature rise and fall. The sealing of pump, oil saturation vapor pressure increases, vacuum degree reduced. Solution is to dredge waterways. Increase the flow of cooling water, the temperature of the oil pump shall not exceed 0 ℃ o l e., it is about 0 ℃.
(3) components assembly is undeserved, cause wear and tear, should be reassembled.

Vacuum quenching furnace water quenching method

Vacuum quenching furnace water quenching method

Everyone at the time of vacuum quenching furnace of water quenching, must operate in accordance with the requirements! The following is the vacuum quenching furnace water quenching in detail:
Quenching furnace body is made up of steel and steel plates welded together, the inner wall of the furnace lining is made of stainless steel plate connected to the furnace shell into a whole, within the furnace andfurnace sandwich filling aluminum silicate refractory fibre and used as heat insulation. The oven door design at the bottom of the furnace body, that is to say into or out from the bottom of pass in and out of the artifact. The furnace under the mouth open, oven door closed action with the method of mechanical transmission, through the motor, reducer, chain wheel, chain, guide rails, etc. Heating elements with high resistance alloy resistance band, through a dedicated link arrangement on both sides of the tank, insulation and bladder.
The ventilator is composed of blower and wind deflector, blower motor electrical chain, with the heating element only when the blower after connect to electricity, heating element which can guarantee the heating element can work under the condition of the ventilation and circulation. The charging basket and in and out of the skip by steel welded together, and make adjustment level of center of gravity, lifting up and down. This furnace is equipped with baskets and furnace to ensure that users can work in a timely manner. Feed, feed baskets on the car, pull and push, into the furnace bottom, furnace door open and Yang machine work, hook on the chain, the charging basket hanging charging, shut down the stove for heating. Discharge, open the oven door, turn Yang motor, the charging basket into a pool of water quenching process, and then the material basket on car of the water surface, chain hook, Yang machine upgrade, pull the car out, aging treatment.
At the bottom of the furnace body is equipped with a pool of water, so that the workpiece in this short time into the pool. Control part adopts thyristor, digital readout of temperature control and alarm, etc. Electric furnace in the oven door closing mechanism and loading lifting structure with limited position switch, this switch contact control cabinet power supply, when the workpiece rose to the highest point, turn on the oven door closed power supply, and the contact element power supply. When the oven door to open, to cut off the heating element power, lifting mechanism and connected power supply, quenching furnace decreased artifact for water quenching.

Excellent performance of vacuum furnace

Excellent performance of vacuum furnace

The pressure inside the chamber of a stove or furnace smoke into industrial furnace is lower than the atmospheric pressure. Vacuum furnace heating power, the heated surface oxidation, no decarburization, small deformation, the mechanical performance is good. Use the vacuum furnace smelting metal to remove impurities, less finished pinhole, segregation of small, good quality. Vacuum furnace is suitable for the high quality, high purity, refractory metal melting and heating, such as tungsten, molybdenum, tantalum, niobium, titanium, heat-resistant alloy steel smelting and magnetic materials, electrical materials of high strength steel, stainless steel, tool steel and die steel, heat treatment.
Before and after vacuum furnace appeared in the 1930 s. In 1927 the United States made electrical material vacuum annealing furnace. Vacuum since 1953 arc furnace power consumption in industry have been used for melting titanium sponge. Before and after the '50 s vacuum induction furnace is widely applied in industry. In 1960 the United States developed oil quenching vacuum furnace.

The basic principle of the vacuum furnace and performance advantages

The basic principle of the vacuum furnace and performance advantages

1.1 the principle of vacuum furnace and structure
Mainly by the furnace, smoke tube, heating coil and a chimney. Using the negative pressure of steam heat exchange technology, the runtime will be used as heat medium of the liquid level control between the smoke and fire tube and the heating coil, the pressure in the furnace is made by high temperature exhaust gas pressure, operation and control the negative pressure condition. Full combustion of fuel burner, heating tube and the fire heat pipe is passed to the pot shell intermediate medium water, boiling water is heated by the liquid into gas phase evaporation, water vapor gradually filled with gas phase space of the furnace body, because the coil is the heating medium and the tube wall temperature is lower than the steam temperature, so that the vapor in the outside wall of the condensing coil, and the heat transfer medium to coil. After the condensation water in gravity whereabouts backwater space. Cycling heat process was realized. To take the negative pressure of heating furnace operations, mainly considering the security issue, the normal pressure will cause the high temperature furnace flue gas leakage, heat loss increase, not only will cause the destruction of the stove itself and the harm to personal safety.
1.2 the advantages of vacuum furnace
(1) safe and reliable, energy saving water. Negative pressure, can be exempt from explosion hazard.
(2) the furnace combustion, the system is not easy to scale. Using pipe, corrugated pipe do itself as a thermal compensation device, with self-cleaning heat bilges cold shrink role, is not easy to scale.
(3) high thermal efficiency, environmental protection and energy saving. Adopts the design of positive pressure combustion type, ensure high efficiency heat transfer, fuel efficiency as high as more than 99%, compared with the traditional boiler, fuel can save about 17%; Low nitrogen oxide and carbon monoxide generation makes flue gas emissions clean, no pollution to the environment.
(4) the fuel adaptability is extensive, natural gas is a plus.
(5) the high degree of automation control, the user can on-demand configuration.

Installation of tubular vacuum furnace

Installation of tubular vacuum furnace

1. vacuum furnace Please read this manual carefully before installation
2. Be careful when installation, can't touch quartz tube, parts clean up first
Assembly sequence: external pressure ring 1 from quartz tube into the first, then 1 set of silicone rubber o-rings into, again to set into the internal pressure ring, silicone rubber o-rings then 2 sets into; Strike two silicone rubber circle to the right position, go up to 2 sets of external pressure ring. (note: at this time should adjust within two silicon rubber o-rings and pressure ring position, make the quartz tube end not on outer pressure ring end face, the 2 mm gap) should be reserved.
After installed the diagram below, the appropriate pressure, no card.
The M5 * 30 with inner hexagon spanner socket head cap screw screwing in; (note: before screwing in the tag, again on the threaded hole, screwing should be one by one, each bolt screwing in 90 degrees, so the three screws tighten. Absolutely can't tighten a screw to spin again after another two, to ensure that the three screws evenly at the same time below after tightening the screw assembly of air inlet pipe, valve and pressure gauge assembly: installed at one end, and then insert the quartz tube furnace lining, the quartz tube at the other end also according to the above method to install. After installation of both sides, adjust the quartz tube in the center of the furnace body, then good trachea, the installation is complete.
