BRY Air-cooled heat pump

Description of BRY type air-cooled heat pump

BRY type air-cooled heat pump is suitable for conveying not weak corrosive, high temperature liquid containing solid particles, suitable temperature - 20 ~ + 350 ℃, can also according to user needs, choose different material flow components, handle liquid is corrosive or other special performance.

USES:

Petroleum and chemical industry, textile printing and dyeing industry, dye industry, wood processing, plastic and rubber processing industry, food industry, paper printing and other industries.

Structural features:

The pump is sealed with soft packing and has good thermal adaptability.

No additional cooling equipment, low operating cost.

Performance advanced efficiency, small volume, low noise, long - term stable operation.

BRY pump for axial suction, foot support structure, BRYG for the pipeline type.

1. Methods to reduce the sealing temperature of hot oil pump:

(1) domestic pump in a sealed cavity around a cooling jacket, with cold water for cooling, can make the seal chamber temperature down to 200-250 ℃.

(2) of single end face seal, the injection flush, SZ - 360 water ring type vacuum pump clean from the outside world, the temperature about 100 ℃ wax (generally don't use diesel, because diesel is finished), both to reduce the temperature, and improved working conditions, is effective.

(3) use cold water on the outside of the gland;

In addition to lowering the temperature, it can also prevent the clogging of the downpipes.

2. Sealing structure for heat pump:

(1) single end face seal: adopt injection flush, engineering plastic diaphragm pump rinses minus two line wax oil is about 100 ℃, pressure is higher than sealed cavity * * 0.05 0.05 Mpa.

Hot water (soft water) is used on the outside of the gland for rapid cooling.

You can use one cycle (ten months).

(2) metal corrugated pipe machine seal: compact structure and convenient installation. In the case of the same auxiliary system, the service life is 2**3 times that of the ordinary seal.

(3) double-end machine seal: adopt circular washing and external cooling, the service life is 1.5-2 times that of single end surface.

(4) the friction pair is hard to hard (YG6/YG8, SiC/SiC, etc.), and the heat pump has good effect on the medium with high viscosity, small amount of solid particles or the medium with crystallization.
