This precision testing instrument applies grease to a stainless steel plate and sprays it with water at specified test temperature and pressure. After 5 minutes, the percentage of grease lost in the spray is measured to evaluate water spray resistance. The system features a magnetic pump for circulating cooling medium, insulation-sleeved circulation pipes, an acrylic spray chamber for easy observation, and a precision pressure gauge for accurate spray pressure monitoring.

Frequently Asked Questions
What is this equipment used for?
This instrument evaluates the ability of grease to adhere to metal surfaces when subjected to direct water spray. It measures the percentage of grease lost during spraying to assess water spray resistance.
What standards does it comply with?
The instrument complies with SH/T 0643-97 and ASTM D4049 standards.
How does the test work?
Grease is applied to a stainless steel plate and sprayed with water at specified test temperature and pressure. After 5 minutes, the percentage of grease lost in the spray is measured.
What is the temperature control?
Temperature is controlled at 38±0.5°C using a digital PID temperature controller.
What is the working water pressure?
Working water pressure is 40psi ±1psi, controlled via bypass valve adjustment.
What type of nozzle is used?
The instrument uses a precision nozzle with stainless steel construction and diameter of Φ3.18mm.
How is cooling achieved?
Refrigeration is provided by a compressor with external circulation of cold bath. The magnetic pump circulates cooling medium through insulation-sleeved circulation pipes.
What is the spray chamber made of?
An acrylic spray chamber is installed for easy observation, complemented by a precision pressure gauge for spray pressure display.
