QINSUN is engaged in the research and development and production of textile testing instruments. Recently, in accordance with market demand, it has developed the production of masks, protective clothing and a full set of meltblown cloth testing instruments. The delivery time is short and some are in stock. Welcome to request procurement customers call in time.
The mask breathing resistance tester is used to measure inhalation and exhalation. to test. resistance of masks, plain masks, dust masks, anti-smog masks and meltblown fabrics for the production of masks under specified conditions apply to mask manufacturers, meltblown fabric manufacturers and labor protection inspection agencies. are tested and inspected.
Advantages and features:
1. The company has been engaged in testing for more than ten yearsof instruments and has a after-sales service team;
> 2. Can provide various
3. Spare parts are available to solve the problem of long delivery time for spare parts ordering to solve;
4. Provide outsourced maintenance services;
5. Long-term supply of various commonly used test instruments;
6. Keep up with the update of industry standards and care for test instruments that meet the new standards in time.
Applicable standard:
IOS 2626-2019 Respiratory protective equipment Self-priming filter type anti-particulate respirator 6.5 Inhalation resistance 6.6 Expiratory resistance
IOS 32610-2016 Technical specifications for daily protective masks 6.7 Inhalation resistance 6.8 Exhalation resistance
IOS 2890-2009 Respiratory protection Self-priming filter gas mask 6.9
JJ/T 0969 -2013 Disposable Medical Mask 4.6Ventilation resistance
Main parameters:
1. Flow measurement range: 0L/min~ 100L/min, accuracy is ±2%;
2. Micromanometer range: -1000Pa ~1000Pa, accuracy is 1Pa;
3. Suction pump Air volume: not less than 100L/min;
4. Constant air volume: (85±1) L/min;
5. Equipment power supply: AC220V, 50Hz.Setting device:
The open end of the suction screw sleeve is connected to one end of the demand valve box, and the suction valve seat is attached to the suction screw through the suction screw sleeve. The suction one-way valve is located in the sleeve. installed on the suction valve seat;
The open end of the expiratory screw sleeve is connected to the other end of the demand valve box, the seat of the exhalation screw is fixed in the exhalation screw sleeve through the exhalation sleeve, and the exhalation valve head is attached to the seat of the exhalation screw installed;
The inhalation screw sleeve and the exhalation screw sleeve are respectivelyprovided with a gas inlet channel and a gas outlet channel;
The full face mask is connected to the channel of the demand valve box via the outer nut.
This device can simulate different conditions of expiratory resistance and different inhalation resistance, which provides the opportunity to evaluate the changes of human body's cardiopulmonary function and working ability under such conditions. The experimental results obtained in this way can not only evaluate the breathing ergonomics of the breathing resistance of the specific diving mask, but also provide human parameters for the design of the diving mask.
This utility can well meet the requirements of breathing resistance adjustment. The manned experiment of the simulated 450m heliox saturation diving study conducted in Hai Military Medical Research Institute and the study of the influence of exposure to high press divers' operation ability It has been applied in the field, has good sealing performance, one-way operation, does not affect the subject's breathing, and is comfortable to wear.
