How to check the quality of the Brake Vacuum Pump?

Pulished on Nov. 14, 2019

Brake pumps are divided into master pumps and sub-pumps. First of all, check the sub-pump. Generally, the fault of the sub-pump is oil leakage. As long as there is no oil leakage, there is generally no problem. Then there is the master pump. When you step on the brake pedal, keep the pedal should not fall down. If it falls, the master pump will be relieved. After the flame is turned off, the brakes will be increased continuously. The brakes will increase. It will be harder. When the brakes are applied and the engine is started, the brakes will soften back to the position. This is the way the main vacuum pump works normally. The pump is better. The jack is checked. The wheel, one person turns, one person can brake to know if the pump is good or bad. A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physicochemical method to evacuate a pumped container to obtain a vacuum. In general, a vacuum pump is a device that uses various methods to improve, create, and maintain a vacuum in an enclosed space. According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely, a gas trap pump and a gas transfer pump. It is widely used in metallurgy, chemical, food, electronic coating, and other industries. The vacuum booster is an important part of the brake system. Its performance and damage to components will directly affect the safety of the car. Therefore, the performance and failure of the vacuum booster should be checked in time, and the Vacuum Brake Booster Kits should be properly adjusted for repair or replacement.

Next, as an EV Brake Booster Vacuum Pump Supplier, share with you how to check the brake vacuum pump:

1. Turn off the fire and step on the brakes.

2, then step on the brakes and fire to see if the brakes go down.

Common brake vacuum pump failures and troubleshooting methods are as follows:

(1) The maximum vacuum of pump extraction is low, and the pump extraction time is prolonged. The cause of the failure is insufficient lubrication and lubricating fluid; air leakage from the suction line; wear of parts; increased leakage through the gap. Trouble diagnosis and troubleshooting: Check the viscosity of the lubricating oil. If it is not qualified, replace the oil of suitable viscosity; check whether the pipeline is leaking. If it leaks, replace the leaking parts; check the parts for wear and tear, if there is wear Repair or replace new parts; check lubricant pressure and meet specified requirements.

(2) The pump does not hold pressure and leaks. Cause: The leak of the seal ring is diagnosed and eliminated: Check the seal for wear and elasticity. If there is wear, replace the seal.

(3) Leakage at each interface Cause: The connector is loose or the seal is damaged. Trouble diagnosis and troubleshooting: Check if the connector is loose. If it is loose, add sealant to tighten the joint; if the seal is damaged, replace it with a new one.
