Because of the high uniformity of the temperature field due to its own circulating system, cryogenic coolant circulating pumps are increasingly used in cryogenic coolant circulating pumps. The Sino-brand DL series cryogenic coolant circulating pump adopts an air-cooled totally-enclosed compressor refrigeration and microcomputer intelligent control system to provide low-temperature circulating cooling water (liquid) flow or low-temperature constant-temperature water (liquid) flow to meet the use of cooling water and low temperature Liquid to cool or thermostatic instruments, widely used in petroleum, chemical, pharmaceutical, life sciences, metrology, light industry, and scientific research and other fields.
What are the precautions for using a cryogenic coolant circulating pump?
[1] Liquid medium (pure water, alcohol, and antifreeze solution) should be added to the tank before using the low temperature coolant circulating pump. The medium liquid surface should not pass through the cooling coil in the tank and should be less than 20mm below the table.
[2] Power: 220V 50Hz, power supply power should be greater than the total power of the instrument, the power supply must have a good "grounding" device;
[3] Avoid acid-base substances entering the tank to corrode coils and liners.
[4] The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument.
[5] Always observe the level of liquid in the tank. When the liquid level is too low, add liquid medium in time.
[6] When the operating temperature of the low-temperature coolant circulating pump is low, care should be taken not to open the upper cover and not to enter the tank in order to prevent frostbite;
[7] After use, all switches are turned off and the power is turned off.
[8] During the external circulation of the liquid, the customer should pay special attention to the firmness of the outlet pipe to prevent it from falling off to prevent the liquid from leaking out.
[9] The instrument should be cleaned regularly. If it is not used for a long time, empty the media in the tank and clean it to keep the work table and the operation panel clean;
The GYQS1500E Road Sweeper is mainly applied to get rid of the solid foreign matters such as the bleeding cement and soil clod on the pavement path of road and bridge, and brush the dust away, as well as clean adhesive layers. Its nylon brush is alternative for routine road cleaning.

Performance
1. The streamlined cabin of the road sweeper owns strong and stable structure, good sealing and sound insulation performance, equipped with integrated overhead air conditioner, makes a comfortable and safe operation environment.
2. This machine is regular tricycle structure of automated ground drive, which concentrates mechanical unit, electrical unit and hydraulic unit all in one, with features of novel, brief, light and flexible structure.
3. Key parts of hydraulic unit are all from the famous manufacturer in the world, such as complete hydraulic transmission, brushing and traveling of infinite variable speed.
4. Hydraulic swing device can swing no more than 15 degrees to left and right and shoot out the collected matters directionally.
5. Optional side brush is easy to be installed and detached, for sweeping the dead corners formed by curbstones and road barriers.
6. Hydraulic lifting device and adjustor will get the brush holder within the upper and lower limits, and freely adjust the sweeping force.
7. Hydraulic steering system is flexible and convenient.
8. The air inlet of engine air filtering system is highly mounted with pre-filter, and the dry and wet composite desert air filter with two-stage filtration keeps the engine longer service life.
9. Steel brush of the road sweeper is made by special processing technology, which will effectively brush the impurities on the pavement powerfully, with advantages of high level of mechanization and good brushing performance.
10. Dash panel with brush pushing-down scale indicator on the right side can show the brush pushing-down scale value and contact face area with ground for a better work of the brush.
11. Strong wind produced by blower system will blow the impurities and dust away directionally to improve the pavement cleanness and effectively improve working efficiency, which provide reliable safeguards for the next construction procedure, especially for the construction technology which requires high viscosity.
12. The electrical control system of the road sweeper applies components meeting the standard of automobile industry; electrical master control box with optimized circuit protects the electrical components if any faults and makes itself easy to repair and maintain.
